Description
Technical field
The present invention relates to a kind of caliberating device of displacement meter, the Fast Calibration for guy type displacement meter, belong to instrument class.
Background technology
Guy type displacement meter is that a kind of relative displacement commonly used measures device, its range commonly used is between 5mm to 500mm, when laboratory and on-the-spot test, all need its sensitivity is checked and calibrate, especially in experimental enviroment, usually utilize and manually pull out bracing wire and utilize steel tape to carry out assisted calibration and demarcation, not only stated accuracy can't guarantee, operation is very inconvenience also.And adopt metering to carry out normal calibration with vernier caliper demarcation frame, not only cost is higher, and the adjustment and installation cycle is also longer, for displacement meter, is demarcated in working order, lacks at present also simple and effective caliberating device.
Summary of the invention
Based on the problems referred to above, the present invention proposes a kind of Quick calibration bench for draw wire type displacement meter, and its technical solution is:
Quick calibration bench for draw wire type displacement meter, it comprises base 1, equally spaced pilot hole 4, stay column 5, block 2 for the fixed displacement meter, screw 3 and displacement meter standing screw 7 for fixed displacement meter 8, have equally spaced pilot hole 4 on base 1, base 1 is provided with the block 2 of the projection of fixed displacement meter in a side of pilot hole 4, the same side of base also has screw 3 away from pilot hole 4 ends, in screw 3, be provided with for displacement meter 8 being withstood on to the displacement meter standing screw 7 on block 2, by the block 2 of projection on base 1 and the screw rod 7 be installed in screw 3, displacement meter 8 is fixed on base 1, also include a stay column 5 for being connected with displacement meter bracing wire 6 inserted in pilot hole 4, by the stay column 5 be installed in pilot hole 4, regulate the extension elongation of displacement meter bracing wire 6 to produce the displacement of determining difference.
There is an aperture described stay column 5 upper ends, pass a drag hook passed for displacement meter bracing wire 6 in hole.
The diameter of described stay column 5 is identical with the internal diameter of pilot hole 4, so that stay column 5 is gapless, is inserted in pilot hole 4.
Described stay column 5 can move up and down in pilot hole 4, to guarantee that displacement meter bracing wire 6 is in level.
Described pilot hole 4 is linearly equidistantly arranged.
Owing to adopting technical scheme as mentioned above, the present invention has following advantage: the present invention's distance between pilot hole in use is known quantity, utilize the movement of stay column between equidistant pilot hole to realize stretching out or retracting of displacement meter bracing wire measured length, can be in the situation that do not need to utilize other high-precision measuring tool (as vernier caliper etc.) to realize the quick field calibration of guy type displacement meter, and simple structure, easy to use, cost of manufacture is low.

Fig. 2 is vertical view of the present invention;
Fig. 3 is three-dimensional structure stereographic map of the present invention.
1. bases in figure, 2. block, 3. screw, 4. pilot hole, 5. stay column, 6. displacement meter bracing wire, 7. screw rod, 8. bracing wire displacement meter
Embodiment
Below in conjunction with accompanying drawing, enforcement of the present invention is further described:
This Quick calibration bench for draw wire type displacement meter is by base 1 as depicted in figs. 1 and 2, protruding block 2 on base, base is away from the screw 3 of pilot hole one side, straight equidistant pilot hole 4 on base, but gapless is inserted the stay column 5 in pilot hole, has certain-length screw rod 7 and forms.
Base 1 can adopt low carbon steel plate, corrosion resistant plate, aluminium alloys etc. carry out machine work and make, length need be greater than the work range (generally in 600mm) of guy type displacement meter, its width should slightly be wider than the width of guy type displacement meter 8, in block 2 height 5mm, clear space between block 2 and screw 3 should guarantee that guy type displacement meter 8 can be placed in therebetween, the general desirable 2-4mm of the diameter of pilot hole 4, spacing is got 10mm to 50mm according to the guy type displacement meter range, pilot hole 4 should have an aperture to equidistant arrangement stay column 5 upper ends along the length of base, pass a drag hook passed for displacement meter bracing wire 6 in hole, sewing needle that also can be with holes with an end replaces, the short steel column that also can process different length is standby.The drag hook that displacement meter bracing wire 6 can be done by thin wire is fixed on stay column 5.
The principle of work of Quick calibration bench for draw wire type displacement meter is:
Guy type displacement meter is being carried out to timing signal, at first guy type displacement meter is placed between block and screw, by rotating screw bolt, thereby its afterbody that compresses displacement meter is fixed, connect displacement meter power supply and metric data line, then the free end of displacement meter bracing wire be connected with stay column and stay column inserted in the pilot hole of correct position, utilizing multimeter or data acquisition equipment to measure the output voltage u of guy type displacement meter
1, then mobile stay column, to another pilot hole, is counted Δ according to the known displacement meter bracing wire of pilot hole spacing overhang, and then measures the displacement meter output voltage and count u
2, the sensitivity coefficient between known output voltage and Displacement Feedback value is k=Δ/(u under a proportional relationship
2-u
1).Measure and can demarcate the linearity of displacement meter in whole range ability by a plurality of pilot holes, utilize data acquisition equipment to record in the situation of displacement readings value and also can obtain very easily sensitivity amendment coefficient and zero value partially.
