Description
Technical field
The invention belongs to and be combined in or be disposed at or be exclusively used in relevant work operative turntable of lathe or rotating disk field specially, be specifically related to a kind of liquid dipping numerical control turning table.
Background technology
In fields such as machine-building, accurate detections, often need some can be operated in whirligig in the liquid environment, as the cutting fluid environment of machining, the water environment of Ultrasonic Detection etc., this just requires this device to have excellent sealing performance.If protection is not in place, will cause component of machine and motor to damage.
The structure great majority that numerical control liquid soaks the turntable product are to adopt servomotor to drive the structure of turntable rotation to liquid level bottom transferring power from liquid level top by worm gear, worm screw or synchronous band.The manufacturing process complexity of this numerical control rotating platform is had relatively high expectations to manufacture level.At present the level of this series products differs bigger, and its reason just is the difference of manufacturing capacity and level, most critical be that the manufacture difficulty of key components and parts such as worm gear, worm screw, synchronous pulley is big and technology is complicated; Because driving-chain is longer, and the transmission accuracy of turntable is subjected to very big influence because of the accuracy of manufacture of crucial driving member, precision is difficult to improve on the other hand.
Summary of the invention
The purpose of this invention is to provide a kind of liquid dipping numerical control turning table.Liquid dipping numerical control turning table can satisfy on the engineering of various liquid environments is used user demands such as good seal to rotary part, high accuracy, reliable operation preferably, and manufacturing process is simple, driving-chain is short, barrier propterty is good.
The present invention adopt servomotor directly the mode of driving drive turntable, only some is immersed in the liquid medium liquid dipping numerical control turning table when working in using system, guarantee the liquid medium turntable inside of not bleeding by dynamic and static sealings at different levels and discharge opeing two-stage safeguard procedures, avoid turntable machinery and electric component produced and destroy.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of liquid dipping numerical control turning table is provided, includes turntable seat, pressure ring, rotating shaft, pressurizing nut, pressing spring, turret supports ring, motor cabinet, servomotor and O RunddichtringO, bearing, bearing (ball) cover.Turntable seat profile is made up of two different cylinders of diameter up and down, and cylindrical portions may evenly is provided with several tapped through holes and a screwed hole above the turntable seat, is provided with two bearings in the turntable seat.The turntable seat is fixedly installed on the turret supports ring, rotating shaft is arranged on the center of turntable seat and turret supports ring, be provided with top bearing cover and lower bearing end cap between turntable seat and the rotating shaft, top bearing cover is connected with the turntable seat by screw respectively with the lower bearing end cap.Servomotor is fixed on the motor cabinet by screw, and motor cabinet is fixedly connected on the turntable seat by screw.The motor shaft of servomotor is connected with rotating shaft by shaft coupling, rotating shaft is by two bearings that are arranged in the turntable seat, and by the servomotor driven rotary, the nut that is arranged on the rotating shaft is tightened by screw thread and rotating shaft, prevents the axial float of rotating shaft.Cylindrical portions may is provided with belt groove above in the turntable seat, is connected with discharge opeing on the screwed hole that is provided with in the ring-shaped groove and connects mouth.Be provided with the O RunddichtringO between rotating shaft and the top bearing cover, be provided with the O RunddichtringO between rotating shaft and the lower bearing end cap, be provided with the O RunddichtringO between turret supports ring and the rotating shaft, be provided with pressure ring between turntable seat and O RunddichtringO, pressure ring directly contacts with the O RunddichtringO.Equally distributed tapped through hole is provided with pressurizing nut on the turntable seat, is provided with pressing spring in the pressurizing nut, and pressing spring supports pressure ring.Described turntable seat, turret supports ring, pressure ring and rotating shaft are coaxial setting.Described O RunddichtringO is supported by pressure ring, and pressure ring is supported by pressing spring.The number of the tapped through hole that evenly is provided with on the described turntable seat is 3～8.
The rotating shaft of liquid dipping numerical control turning table of the present invention by be installed in the turntable seat two bearings and by the servomotor driven rotary, two bearings are by the turntable seat and the metal (upper end cap is spacing and the location, rotating shaft axially and radially spacingly realize by nut and bearing.Work top and rotating shaft are made as one, and the upper surface of rotating shaft is work top, can be used for clamping workpiece.
Liquid dipping numerical control turning table of the present invention is by realizing that to the gap between parts in the turntable dynamic and static sealing constitutes the one-level protection with the sealing ring sealing.Anti-leak movable sealing between inner rotating shaft of turntable and the turret supports ring and rotating shaft and bearing the grease lubrication movable sealing between the end cap are up and down all realized by the O RunddichtringO; Contact-making surface anti-leak static seal also adopts the O RunddichtringO between the work tank base plate in turret supports ring and the using system, thereby has guaranteed that liquid does not bleed in the turntable.In order to reduce because anti-leak dynamic seal ring wearing and tearing cause the generation of the bad and leakage situation of sealing property between the rotation composition surface, by pressure ring sealing ring is applied precompression with equally distributed several pressing spring, and the elasticity of utilizing pressing spring self adaptation in to a certain degree guarantees the sealing property between sealing ring and rotating shaft rotation composition surface, the size that can regulate precompression by the adjusting pressurizing nut.
