In one possible implementation of the invention, the tool holding device is connected in the connecting state with exactly one tool holder base insert. In this embodiment, it is provided that the two rail wing sections of the tool holder device engage in the two rail sections of the tool holder base insert. Due to the plate-shaped design of the tool holder base insert a secure, tilt-proof and comfortable attachment of the tool holder device is achieved. In an alternative embodiment of the invention, the tool holding device is connected in the connecting state with two, in particular exactly two, tool holder base inserts. In this embodiment, at one end portion of the tool holding device with a rail wing portion of the tool holder means is given a connection with one of the tool holder base inserts and at the other end portion with the other rail blade portion a further connection with the other tool holder base insert. In this embodiment, it is possible to provide tool holding devices which extend across a width in the transverse direction over exactly two toolholder base inserts or, if there are clearances between the toolholder base inserts, extend over a greater width. In a preferred embodiment of the invention, the tool holder assembly comprises a plurality of structurally and / or functionally different tool holder devices and a plurality of tool holder base inserts, which are each identical in construction. With this set of tool holding devices and tool holder base inserts, it is possible to populate and customize a breadboard in a desired manner, in particular, the tool holder assembly comprises the breadboard. The tool holder assembly may be formed, for example, as a tool cart, wherein the hole grid plate is arranged on a front side of the tool carriage and secured thereto. The tool holder inserts can be optionally placed on the breadboard. In particular, the tool holder inserts make it possible to form rows and columns and to arrange the tool in any desired manner, in particular in a more visually ordered manner.

Particularly preferably, the tool holder device and / or the tool holder base insert are designed as a plastic part, in particular in each case as a one-piece plastic part, in particular a plastic injection-molded part.

It is preferred that the Entformungsrichtung for the tool holder base insert is aligned perpendicular or substantially perpendicular to the mounting plane and / or the surface extension of the breadboard. Thus, the Entformungsrichtung is rectified rasterwand with a plug of the tool holder base insert in the hole. In contrast, it is preferred that the Entformungsrichtung the tool holder means is oriented perpendicular or substantially perpendicular to the Entformungsrichtung for the tool holder base insert and / or rectified to the mounting direction. Thus, the Entformungsrichtung is oriented to the mounting direction and on the other hand in many cases rectified to a loading direction for equipping the tool holding device with tools. In a preferred embodiment of the invention, the or one of the tool holder devices is designed as a forceps holding device, wherein the forceps holder means one or more receptacles for a first pliers leg of a pair of pliers and cheek sections, which for guiding a second pliers leg of the same pliers in the transverse direction offset from each other on the pliers holding device are arranged. By the cheek sections is achieved that the pliers, in particular the second pliers limb, can not swing freely and can penetrate into the gripping area of an adjacent tool holder. On the other hand, it is achieved by the cheek sections that the pliers are easy to grip and easy to put down.

The tool holder base insert has a support surface, wherein the tool holder base insert in the assembled state rests with the support surface on the perforated grid plate, in particular on a front side of the perforated grid plate.

In a preferred embodiment, the disk interface has at least one hook device, wherein the hook device projects beyond the bearing surface in a plug-in direction of the tool holder base insert into the perforated grid plate, in particular perpendicular to the bearing surface. The at least one hook means, some or all of the hook means is arranged relative to the support surface so that the hook means in the assembled state of the tool holder base insert can each pass through one of the receiving holes and project on the opposite side. If one looks more closely at the hook device, then it has one

Hook legs and a hook head, wherein the hook head is arranged on the hook leg. In particular, the longitudinal extension of the hook head is aligned perpendicular to the longitudinal extent of the hook leg. In particular, these form a reversed L-shaped hook in a side view. Together, the hook leg and hook head form a plate receiving portion for receiving a portion of the plate body, namely a plate edge portion facing the receiving hole into which the hook means is inserted. The hook device thus surrounds the Recording hole forming edge plate area. The hook leg forms a positive contact surface for the plate edge region and extends in particular perpendicular to the support surface. Over the contact surface, the tool holder base insert can be supported on the perforated grid plate, in particular on the facing plate edge region, in a loading direction. For example, if the breadboard is a vertically arranged breadboard, the loading direction is directed from top to bottom so that the hook means is opened downwardly and / or in the loading direction. The hook device lies with the contact surface on the plate edge area. The hook head engages over the plate edge region in the loading direction, so that the plate edge region is arranged between the hook head and the bearing surface.

Furthermore, the tool holder base insert comprises at least one securing device, which is arranged in the assembled state of the tool holder base insert in one of the receiving holes, in particular such that the securing device engages in or engages through the receiving hole. The securing device serves to secure the tool holder base insert in a form-locking manner against displacement relative to the perforated grid plate counter to the loading direction. Thus, the tool holder base insert is positively secured in the loading direction by the positive contact surface of the hook leg and against the loading direction by the securing device.

Optionally, in addition, it is proposed that the tool holder base insert has a main body section and a securing section. Of the

Basic body section defines the support surface and carries the at least one hook device. The securing section, in contrast, carries the securing device. The main body portion and the securing portion are arranged to be movable relative to one another, wherein the securing means is elastically deflectable relative to the hook means against the insertion direction, in particular in a straight line or in a pivoting movement. For a deactivation of the securing device, this is deflected relative to the at least one hook device against the insertion in a Entsicherungsposition. For activation of the safety device is preferably provided that this automatically and / or elastically returns to the securing position.

It is a consideration of this embodiment that a tool holder base insert can be created by the use of a security device which is deflectable in a direction opposite to the insertion direction and thus deactivated, which is very insensitive to lateral loads. In a preferred embodiment of the invention, the main body portion and the securing portion are connected to each other via a pivot joint. The pivot axis is particularly preferably arranged parallel to the support surface. The pivot joint allows the pivoting of the securing device relative to the hook device. Characterized in that the pivot axis is arranged parallel to the support surface, the movement of the securing device against the insertion direction is made possible as a pivoting movement.

In a preferred embodiment of the invention, the securing portion is formed as a U-shaped securing bracket, which surrounds the body portion at least in sections and is connected at the free ends via the pivot joint with the base body portion. In particular, the pivot joint forms two pivot sections. In the embodiment as a U-shaped securing bracket, the securing portion can be operated particularly easily by a user, since the connecting leg of the two free legs is easy to grip. For example, it is possible to disassemble the

To pull tool holder base insert on the securing bracket, thereby elastically deflecting and deactivating the securing device against the insertion direction, so that the tool holder base insert can be disassembled. Particularly preferably, the base body portion is T-shaped, wherein the standing leg of the "T" between the legs of the "U" of the securing bracket is arranged. Particularly preferably, the end region of the upright leg of the "T" is designed as a first operating region, wherein the assembly can be effected by pressure loading on the first operating region. In this embodiment the tool holder base insert presents itself as an easy-to-use, shapely and / or compactly designed workshop component.

In a preferred development of the invention, the tool holder base insert has at least two of the hook devices. The hook heads of the at least two hook devices are arranged to be compatible with an imaginary positioning hole grid. The Positionierlochraster corresponds in the pitch of the plate hole grid and is used in the present description as a first auxiliary construction.

The hook legs of the at least two hook devices are arranged to be compatible with an imaginary fixing hole grid. The grid dimension of Fixierlochrasters corresponds to the grid dimension of the plate hole grid, wherein the Fixierlochraster represents a second auxiliary construction. In particular, the hook heads may be arranged in the positioning hole grid and / or the abutment surfaces of the hook legs in the Fixierlochraster. The Positionierlochraster is offset from the Fixierlochraster in a mounting direction of the tool holder base insert. When mounting the tool holder base insert in the perforated grid plate, it is initially positioned in a positioning position such that the hook heads of the at least two hook devices are arranged in the receiving holes. In the positioning position, the plate-hole grid forms the positioning-hole grid. In a subsequent step, the tool holder base insert is moved in the mounting direction to achieve a fixing position, wherein the hook legs are arranged in the plate hole grid and these bear against the bearing surfaces in the loading direction at the plate edge regions. In the fixing position, the plate-hole grid forms the fixing-hole grid. Due to the sliding movement in the assembly direction, the tool holder base insert is transferred from the positioning position into the fixing position. Particularly preferred are the at least two hook means, some

Hook means, preferably all hook means, the same orientation, so that the tool holder base insert in the insertion direction in the hole grid plate can be inserted and subsequently moved in the mounting direction, wherein the hook means engage over the plate edge regions.

It is particularly preferred that the at least one securing device is arranged to be compatible with the fixing hole grid and / or incompatible with the positioning hole grid. Compatible means in particular that the securing device etc. fits into the corresponding grid and / or is arranged in the receiving holes. Incompatible means, in particular, that the securing device etc. does not fit into the corresponding grid and / or is arranged outside, in particular shifted, to the receiving holes. In particular, the tool holder base insert is designed so that in the arrangement of the tool holder base insert in the positioning position, the securing device is elastically deflected relative to the hook device against the insertion direction and is in particular inevitably in the armed position. Only after the transfer of the tool holder base insert into the fixing position can the transition of the securing device into the securing position take place.

The securing device is particularly preferably designed such that it rests in the positioning position of the tool holder base insert on the perforated grid plate, in particular on a front side of the perforated grid plate and is inserted into the corresponding receiving hole only after transfer of the tool holder base insert into the fixing position or elastically snaps. In order to simplify the insertion into the corresponding receiving hole is proposed to introduce a control slope on the securing device. The control slope is arranged on the securing device such that the edge region of the perforated grid plate can slide in the receiving hole during insertion of the securing device. Due to the control slope is at a pressure load perpendicular to the breadboard on the tool holder base insert the safety device and thus the

Tool holder base insert shifted in mounting direction. In particular, the control slope thus forms an auxiliary gear section for mounting the tool holder base insert. In a particularly preferred embodiment of the invention, the securing device is designed as a web section, wherein the web section can be positively supported with a web end counter to the loading direction on the plate edge region. Thus, the fixing position of the tool holder base insert is fixed to the web end opposite to the loading direction and on the other by the contact surface of the hook leg in the loading direction. Optionally, in addition, it can be provided that the web portion can also be supported with the other web end in the loading direction on the plate edge region. However, since this can lead to an over-definition of the tool holder base insert, it is more preferred that in the loading direction, the web end is set back slightly relative to the contact surface. It is particularly preferred that the securing device and one of the hook devices are arranged in the assembled state of the tool holder base insert and / or in the fixing position in a common receiving hole. Alternatively or additionally, the securing device and the hook device are positioned in the Justierlochraster in a common receiving hole. This positioning has the advantage that the bilateral positive support of the securing device, in particular the web end, and the hook leg, in particular the contact surface, takes place within a very small area, so that no tilting or other disturbances can occur. Further, the number of required receiving holes for mounting the tool holder base insert is reduced, so that more of the tool holder base inserts or the tool holder base inserts can be arranged closer to each other on the breadboard, since no separate receiving hole for the securing device must be kept free. One aspect relates to a method for assembling the at least one

Tool holder base insert on the breadboard of the toolholder assembly. The method comprises placing the tool holder base insert on the perforated grid plate in the positioning position, the at least one hook device with the hook head each being inserted into a receiving hole of the perforated grid plate. The at least one securing device, however, stands on the breadboard. In a subsequent step, the securing device is deflected into the releasing position, which can be implemented, for example, by a pressure load on the basic body section, in particular on the first operating area, the hook heads dipping further into the receiving holes, but the securing device on the front side of the perforated grid plate positive fit. In a subsequent step, the tool holder base insert is displaced relative to the hole grid plate in the mounting direction, so that the plate edge portions of the plate body of the grid plate can enter into the plate receiving portions of the hook means. This sliding movement can be supported by the control slope or bevels of the fuse elements, as they slide during insertion or immersion along the edge regions of the perforated plate grid along, while moving the tool holder base insert in the mounting direction. In a subsequent step, the securing devices snap into the receiving holes and move into the securing position, so that the tool holder base insert is in the fixing position in the perforated grid plate in the mounted state. Upon release of the tool holder base insert, the securing portion is raised manually, so that the securing device is transferred from the securing position to the releasing position. Subsequently, the tool holder base insert is transferred from the fixing position into the positioning position and can be removed from the perforated grid plate. Particularly preferably, the securing portion has a second operating area for manual lifting, wherein the second operating area is arranged so that the tool holder base insert is pushed in the disassembly direction or at least loaded. Both the mounting and the demounting of the tool holder base insert can each be done with a simple hand movement. In one possible implementation of the invention, the tool holder base insert is designed as a base tool holder base insert, which has at least or exactly four hook devices and has at least or exactly two securing devices. It is preferably provided that the hook devices are arranged in a square pattern and / or in a 2x2 matrix. Particularly preferably, the two securing devices are arranged in the manner of a clip around two of the hook devices within a row, preferably around the two hook devices which are down in the loading direction. It is further preferred that the pivot axis is arranged between, in particular centrally between the two rows of the 2x2 matrix.

In another embodiment of the invention, the tool holder base insert is designed as a supplementary tool holder base insert which has at least or exactly two hook devices and comprises at least or exactly one securing device. It is particularly preferably provided that the hook devices are arranged one above the other in the loading direction and the securing device is positioned next to the lower hook device in the loading direction. It is particularly preferably provided that the mounting direction for the rectified for the tool holder base insert and for the tool holder device, parallel or identical and optionally complementary rectified, is parallel or identical to the loading direction in an advantageous embodiment of the invention, the

Tool holder base insert at least one mechanical plug-in interface for a further tool holding device, wherein the plug-in interface, e.g. is formed as a passage opening. For example, the passage opening may have a circular cross-section, so that a round material, such as a rod, can be introduced.

Another object relates to the use of the tool holder assembly as previously described in the tool holder assembly as previously described has been described, in particular for sliding on at least one of the tool holder base inserts and / or for holding at least one tool. Further features, advantages and effects of the invention will become apparent from the following description of preferred embodiments of the invention and the accompanying figures. Showing:

The receiving holes 4 are square in plan view and have for example a size of 9.2 millimeters x 9.2 millimeters. The receiving holes 4 are distributed in a grid having a transverse direction Q and a longitudinal direction L, wherein the distance between the individual receiving holes 4 in the transverse direction Q or in the longitudinal direction L in each case 38.1 millimeters is. The plate body has, for example, a thickness of less than 2 millimeters.

The tool holder base insert 3 is formed as a one-piece plastic injection molded part and can be divided into two different sections as part of its function. A main body portion 5 is T-shaped in plan view from the front, wherein the transverse or Q extending leg of the "T" extends in the extension in the longitudinal direction L to about 50 percent of the total length of the tool holder base insert 3. Further, the Tool holder base insert 3 has a securing portion 6 which is U-shaped The U-shaped securing portion 6 is opened to the main body portion 5 and surrounds the standing leg of the T-shaped main body portion 5. Specifically, the securing portion 6 forms a securing bracket U-shaped securing portion 6 are integrally formed on the transverse leg of the T-shaped main body portion 5, wherein the transition between the securing portion 6 and the base body portion 5 forms a pivot joint 7, which defines a pivot axis S. The pivot axis S is aligned parallel to the breadboard 2 t and is also located approximately in the middle in the direction of the longitudinal extension L of the tool holder base insert 3. The encompassed by the U-shaped securing portion 6 portion of the base body portion 5 forms a first operating area 19, which for easy identification by a user a corrugation or other friction-increasing Structure has. During assembly of the tool holder base insert, the user presses on the first operating area 19.

By engaging on the lying leg of the U-shaped securing portion 6, the securing portion 6 can be pivoted about the pivot axis S and deflected relative to the base body portion 5. To facilitate engagement, the securing portion 6 may have a recess as a second operating area 20. The tool holder base insert 3 is in

Top view rectangular to square. The surface extension is dimensioned so that immediately adjacent to the tool holder base insert 3 in the adjacent tooling holes 4, a tool holder base insert 3 can be mounted without line or gap between them.

FIG. 2 shows a schematic side view of the tool holder base insert 3, wherein it can be seen that it has hook devices 8 which are arranged offset in height in an assembly direction M.

The hook devices 8 each have a plate receiving region 9, into which a plate edge region of the perforated grid plate 2 can be introduced, the plate edge region coming against a load direction B in a form-locking manner on a contact surface 10 for positive engagement. As a result, the tool holder base insert 3 is held positively in the loading direction B via the hook device 8. The tool holder base insert 3, in particular the base body portion 5, rests with a bearing surface 1 1 in the assembled state or in the fixing position on the front of the perforated grid plate 2 in a form-fitting manner. The hook means 8 extend perpendicularly or approximately perpendicular to the support surface 11. The contact surfaces 10 are perpendicular or substantially perpendicular to the support surface 1 1 aligned.

The hook devices 8 can each be subdivided into a hook leg 12 and into a hook head 13, their longitudinal extensions being arranged perpendicular to one another. The hook leg 12 extends perpendicular or approximately perpendicular to the support surface 1 1, the hook head 13 extends perpendicular or substantially perpendicular to the hook leg 12 and / or parallel or substantially parallel to the support surface 1 first Hook legs 12 and hook head 13 form in the side view shown an L-shaped form and form the

Plate receiving area 9. Furthermore, a securing device 14 can be seen in the side view in FIG. 2, which is designed as a web section which is integrally formed on the securing section 6. The securing device 14, in particular the web section, extends in the mounting direction M and / or load direction B and / or in the longitudinal direction L of the breadboard 2. The one end of the web section is formed as a control slope 21 whose function in connection with the figures 4 a - d is explained. The hook devices 8 and the securing devices 14 together form a plate interface for fastening the tool holder base insert 3 to the perforated grid plate 2.

FIG. 3 shows a schematic three-dimensional representation of the rear side of the tool holder base insert 3. For orientation, attention should again be drawn to the T-shaped body portion 5 and the U-shaped securing portion 6, which are connected to each other movable via the pivot joint 7. The hook devices 8 are integrally formed on the main body section 5. The support surface 1 1 is formed by various structures, such as webs, etc. on the base body portion 5, so that the base body portion 5, the support surface 1 1 defines. By contrast, the two securing devices 14 are integrally formed on the securing section 6 so that they pivot about the pivoting section 6 about the pivoting joint 7 about the pivot axis S relative to the adjacent hook means 8 in a direction perpendicular to the surface extension of the perforated grid plate 2 and / or the support surface. 1 1 can be deflected. It can also be seen in the illustration that the securing devices 14 are arranged adjacent to the hook devices 8 in the lower row, but are displaced or offset in the longitudinal direction L relative thereto.

FIG. 4 a shows a schematic sectional illustration in order to describe the mounting of the tool holder base insert 3 on or in the perforated grid plate 2. The perforated grid plate 2 is shown in triplicate in FIG. 4a, wherein the perforated grid plate 2 is designated here as 2a, b, c. The perforated grid plate 2a is oriented in an insertion direction E, which is oriented perpendicular to the surface extension of the perforated grid plate 2a, b, c and / or perpendicular to the support surface 11, spaced apart from the tool holder base insert 3. This relative positioning is also shown in FIG. 4b.

The breadboard 2b is positioned so that the tool holder base 3 is in a positioning position. In the positioning position, the hook heads 13 of the hook devices 8 are already immersed in the receiving holes 4 of the breadboard 2. In the adjustment position of the tool holder base insert 3, however, the securing devices 14 are supported on the front side of the perforated grid plate 2b. This relative position is shown in FIG. 4c.

If one looks in parallel to this Figure 5, which shows a rear view of the tool holder assembly 1, wherein the tool holder base insert 3 is in the Justierlage, it can be seen that the hook heads 13 are positively received in the longitudinal and transverse direction of the breadboard 2b. The breadboard 2b defines a positioning hole pattern relative to the tool holder base 3.

By loading the main body portion 5 in the region of the upright leg on the first operating area 19 according to arrow A in the insertion direction E is achieved that the hook means 8 of the lower row and the hook means 8 of the upper row are further performed by the receiving holes 4, at the same time the securing means 14 are deflected relative to the lower row of hook means 8 and / or relative to the adjacent hook means 8 against the insertion direction E. Once the hook heads 13 are so deeply immersed in the receiving holes 4 that the back of the breadboard 2b can retract into the receiving areas 9, the tool holder base insert 3 in the mounting direction M and / or later loading direction B relative to the breadboard 2b are moved so that the Tool holder base insert 3 is transferred to a fixing position. In particular, the insertion movement is strictly and / or exclusively parallel to the

Front of the breadboard 2 and 2a, b, c. During the transfer to the fixing position, the securing device 14 slides over the front side of the perforated grid plate 2b. Once the control slope 21 the edge of the Received receiving hole 4, the securing device 14 can slide into the receiving hole 4. By the control slope 21 of the tool holder base insert 3 is further pushed in the mounting direction M, as this translates a translation of the pressurization in the direction of E and / or perpendicular to the breadboard 2 in a translational movement in mounting direction M.

The fixing position of the tool holder base insert 3 is shown relative to the perforated grid plate 2c or in the figure 4d. In the fixing position, the hook devices 13 are supported in the loading direction B via the contact surfaces 10 of the hook legs 12 in a form-fitting manner against the edge regions of the perforated grid plate 2c. Due to the offset of the tool holder base insert 3 relative to the perforated grid plate 2b, the securing devices 14 are now brought congruently to the receiving holes 4, so that they can be inserted in the insertion direction E in the receiving holes 4. In contrast, the hook heads 13 engage over the edge areas of the plate.

This state is shown again in FIG. 6, it being apparent from the synopsis of FIGS. 4 and 6 that the securing devices 14 are positively supported at one end, in particular at the web end, against the mounting direction M and / or the direction of loading B. Thus, the tool holder base insert 3 is arranged both in and against the loading direction B and / or mounting direction M positively in the hole grid plate 2c. Against a removal of the tool holder base insert 3 against the insertion direction E is a backup on the overarching hook heads 13 and recorded in the receiving areas 9 plate edge areas of

Breadboard 2c. Thus, the tool holder base insert 3 is positively secured in each direction of movement.

When dismantling the tool holder base insert 3, the securing section 6 is opposite the main body section 5 around the

Swivel joint 7 is pivoted by a train on the second operating area 20, so that the securing device 14 is pulled out of the receiving hole 4. Due to the pulling movement on the second operating area 20 of the Tool holder base insert 3 against the mounting direction, that is pressure-loaded in a disassembly direction, so that the tool holder base insert 3 in an overall movement of the breadboard 2 is removable. This is achieved in that the pulling movement is oriented counter to the extension direction of the hook heads 13 on the hook means 8.

The position of the hole grid plate 2c relative to the tool holder base insert 3 defines a fixing hole pattern, the fixing hole pattern being disposed offset to the positioning hole pattern with respect to the tool holder base insert 3 in the mounting direction M.

As shown particularly in FIG. 6, the hook devices 8 of the upper row are formed as wide hook means 8, which are also supported in the transverse direction Q at the plate edge portions of the receiving holes 4. In contrast, the hook means 8 are formed in the lower row as narrow hook means 8, which are supported on one side only of the transverse direction Q form fit to the edge areas of the plate. On the opposite side, in contrast, one of the securing devices 14 is arranged in each case in the same receiving hole 4. By arranging both a securing device 14 and a hook device 8 in a common receiving hole 4, tilting and similar interference, which could occur when these components are arranged in different receiving holes 4, are minimized. As can be seen in particular from FIG. 3, the tool holder base insert has

3 a plurality of tubular support sections 15, which are closed in the embodiment shown in Figure 1 at the front. However, these can be opened by a separating machining, for example a hole, and thereby form plug-in interfaces for insertion of a round material, which can be designed as a tool holding device.

Furthermore, the tool holder base insert 3 at the transverse leg of the T-shaped main body portion 5 edge in the longitudinal direction L extending Rail sections 16 a, b, to which an attachment body, such as one of the tool holders 18 described below, can be postponed so that they form a common sliding interface. The tool holder base insert 3 shown in Figures 1 to 6 is square or nearly square in shape and exhibits a 2x2 matrix of hook means 8. This may be referred to as a base tool holder base insert. In Figures 7 and 8, a tool holder base insert 3 is shown as a supplementary tool holder base insert in front view and rear view, having only two hook means 8 superimposed in a 2x1 matrix. The tool holder base insert 3 has exactly one securing device 14, which, however, can again be introduced together with the lower hook device 8 into a common receiving hole 4. The tool holder base insert 3, which is designed as a supplementary tool holder base insert, also has a base body section 5 formed in the shape of a T and a securing section 6 formed in a U-shaped manner, so that the function is referred to the preceding description.

FIGS. 9a and 9b illustrate a tool holding assembly 1 with the breadboard 2 and a plurality of tool holding inserts 3 with different tool holders 18 to illustrate the versatility and modularity of the tool holder assembly 1. The further figures are exemplary embodiments of different tool holder devices 18 shown. The tool holding inserts 3 are arranged substantially in a row, but could also be arranged in any distribution selected by the user himself. The tool holder inserts 3 are made as follows:

The round material is e.g. made of metal, in particular of an aluminum alloy.

XIII-XV: supplementary tool holder base insert with a plastic clamping device as a tool holding device 18, wherein the clamping device has a plurality of plastic bolts which engage in the through holes 17.

In the figure, 9b different tool holder inserts 3 in the use of the rail sections 16 a, b for pushing tool holder devices 18 are shown. For illustration, Figures 10a, b show the tool holder device 18 and the tool holder base insert 3 with the tool holder 18 in detail. The tool holder device 18 is designed as a sliding cap, which can be pushed onto the trained as rail sections 16 a, b rail interface of the tool holder base insert 3 from above in the loading direction B and the tool holder base insert 3 engages positively. The tool holder device 18 may have different holding members, wherein in the examples XVI and XVII hook elements are shown. In Examples XVIII-XXI, sorting boxes for tool inserts or other small parts are shown as tool holding means 18. While in the examples XVI-XIX the tool holding device 18 designed as sliding caps are only pushed onto a single tool holder base insert 3, the tool holding device 18 of the examples XX and XXI is pushed onto two tool holder inserts 3, which are also arranged offset to one another.

FIGS. 10a, b show the tool holder device 18 in a schematic rear view and in an oblique view from the rear. The tool holder device 18 has a slide receptacle 22 into which a slide portion 23 (FIG. 3) can be inserted in the mounting direction. The slider portion 23 is formed as a free end or as a free end portion of the tool holder base insert 3.

The tool holder device 18, more precisely the slide holder 22, has two rail wing sections 24a, b, which extend in the mounting direction M or in the loading direction B. The rail sections 16 a, b (FIG. 3) each have a sliding surface 25 a, b, whereas the rail wing sections 24 a, b each have a mating sliding surface 26 a, b. The sliding surfaces 25a, b face the perforated grid plate 2 in the assembled state, whereas the counter-sliding surfaces 26a, b face away from the perforated grid plate 2. In particular, engage the rail wing sections 24a, b the

Rail sections 16 a, b in the insertion direction E, so that the rail wing sections 24 a, b and in particular the Gegengleitflächen 26 a, b between the perforated grid plate 2 and the rail sections 16a, b or the sliding surfaces 25a, b is located.

The tool holder base insert 3 further has a guide surface 27 which is formed by the front side of the tool holder base insert 3. In contrast, the tool holder device 18 comprises a counter guide surface 28, which is arranged in the slide holder 22 and the tool holder base insert 3 faces so that when mounting the tool holder 18 on the tool holder base insert 3, the counter guide surface 28 can slide on the guide surface 27 along. The counter-guide surface 28 may be formed continuously, or - as shown in Figures 10a, b - be realized only as running in the mounting direction M ribs.

The slide receptacle 22 forms a hood, wherein the end of the hood is formed by a support region 29 to which the free end of the tool holder base insert 3, in particular of the slide portion 23, with a support portion 30 (Figure 3) rests positively. In particular, the support region 30 forms an end stop for the support region 29 in the mounting direction M and / or in the loading direction B.

In order to further improve insertion and threading, a guide wing 31, which engages behind the free end of the tool holder base insert 3 in a connecting state, extends in the transverse direction Q. The guide wing 31 is integrally formed on the tool holder device 18.

With the aim of preventing accidental release of the tool holder 18 of the tool holder base insert 3, the tool holder 18 has two locking device 32a, b, which are designed as latching hooks and which engage latching recesses 33a, b of the tool holder base insert 3 detent. The latching devices 32a, b each form a latching interface with the latching receivers 33a, b, which secures the tool holder device 18 with the toolholder base insert 3 detachably against the mounting direction. Figures 1 1 a, b, c show three states during the sliding of the tool holder device 18 on the tool holder base insert 3 along or rectified to the mounting direction M. By pushing a mounting plane ME is defined at the same time, which is rectified or parallel to the mounting direction M. Further, the mounting plane ME is rectified or aligned parallel to the front of the breadboard 2, In the figure 11a, the tool holder base insert 3 between the mating surface 28 and the mating surfaces 26a, b positively caught and thereby centered in the sliding movement. The game in the direction perpendicular to the mounting plane is large, so that the tool holder device 18 can be easily placed on the tool holder base insert 3.

In FIG. 11b, the tool holder device 18 is slid so far onto the tool holder base insert 3 that the free end of the tool holder base insert 3 is already engaged behind by the guide blade 31, thereby further centering the movement.

Upon further pushing the tool holder device 18 onto the tool holder base insert 3, the latching devices 32a, b are latched into the latching receptacles 33a, b and the connection state is reached. The mating guide surface 28 and the mating sliding surfaces 26a, b hold the tool holder base insert 3 over the guide surface 27 and the sliding surfaces 25a, b without play, almost free of play or even with a certain prestress. By engaging behind the rail sections 24 a, b behind the rail sections 23, the tool holder device 18 in a direction perpendicular to the

Surface extension of the hole grid plate 2 and / or the mounting plane positively secured.

The sliding surfaces 25a, b, Gegengleitflächen 26a, b, guide surface 27 and mating surface 28 may be sized so that in the in FIGS

1 1 a - c, the play in the direction perpendicular to the mounting plane and / or the centering becomes steadily narrower, so that a narrowing up takes place from a coarse uptake to a prestressed state. In FIG. 12, the tool holding device 18 in this case is designed as a forceps holder device in a three-dimensional representation obliquely from the front in a detailed view. Trained as a forceps holder device tool holding device 18 has two receptacles 34a, b, the receiving direction is vertically aligned and forms a receiving channel for a first leg of a pair of pliers. In the tool holder device 18 thus shown, two pliers can thus be inserted in parallel. It should be emphasized that two cheek sections 35a, b are arranged at the edge of the tool holder device 18, which extend in the plane extension approximately perpendicular to the Lochrasterpaltte 2 and / or to the mounting plane and form a lateral boundary for each second leg of the forceps. Together with the boundaries of the receptacles 34 a, b, the cheek portions 35 a, b form a U-shaped area for the second leg of the pliers. In the inserted state of the forceps, the first leg of the forceps is thus caught by the receptacle 34a, b, and the second leg of the forceps is laterally guided by the cheek portions 35a, b, so that the forceps can not oscillate or oscillate uncontrollably. In particular, this ensures that the installation space for receiving the pliers is limited to the extension in the transverse direction Q of the tool holder device 18.

It should be noted that the tool holding inserts 3 in the embodiment as a base tool holder base insert or supplementary tool holder base insert for the tool holding devices 18 in Figures 9a and 9b are each designed to be identical. In particular, these can each be made in a tool and thereby form a highly functional module mounting plate for the
