Vernier caliper is used very extensive in compared with precision measurement, but vernier caliper itself adopts the materials such as stainless steel to make, be easy to expand with heat and contract with cold because of temperature variation, the precision that impact is measured, so in a lot of laboratories, need the equipment that vernier caliper precision is detected, equipment need to have the features such as miniaturization, precision be high, easy to use concurrently simultaneously.
Utility model content
The technical problems to be solved in the utility model is: a kind of miniaturization and vernier caliper detector easy to use are provided, have solved in present many laboratories, generally lack the problem of vernier caliper dedicated test correcting device.
The utility model solves the technical scheme that its technical matters adopts:
An interior clamped-in style vernier caliper detector, comprises two groups of vernier caliper fixed mechanisms and measuring basis assembly, and described vernier caliper fixed mechanism relative measurement fiducial is symmetrical arranged;
Described vernier caliper fixed mechanism comprises slide rail, tooth bar fixed mechanism and claw fixed mechanism;
Described tooth bar fixed mechanism is fixed on slide rail, described tooth bar fixed mechanism comprises two symmetrically arranged tooth bar fixed claws in relative slide rail middle part, on described tooth bar fixed claw, be provided with a straight-line groove, on one of them side of described straight-line groove, be provided with a hold-down bolt, described hold-down bolt is flexibly connected with fixed claw;
Described claw fixing structure comprises two symmetrically arranged fixed claws of relative slide rail middle part mirror image, described fixed claw and slide rail are slidably connected, in described fixed claw, be processed with open slot, described open slot is strip, the openend of described open slot arranges in opposite directions, a described fixed claw dorsad side of open slot is also rotatably connected to a housing screw, described housing screw is flexibly connected by screw thread with tooth bar fixed claw, the start direction of described housing screw is parallel with straight-line groove, and described fixed claw is also slidably connected with slide rail;
Described measuring basis assembly comprises reference block, described reference block is cylindrical, at the center of reference block, be provided with columniform through hole, on described slide rail, be provided with fixed block, the fixed block of described two groups of vernier caliper fixed mechanisms is inserted in the cylindrical hole of reference block.
As further innovation of the present utility model, between described fixed block and columniform through hole, be interference fit.
As further innovation of the present utility model, on the movable end of described hold-down bolt, be also provided with clamping piece, described clamping piece and hold-down bolt are rotationally connected.
The beneficial effects of the utility model are:
1, the utility model, by a reference block, by vernier caliper is contrasted between two, is exactly the detection realizing vernier caliper very easily, and mounting blocks is prompt, simple in structure.
2, reference block adopts interference fit, has improved stability.
3, because can there is certain stress deformation in the claw of vernier caliper, so adopting open slot to be fixed, the utility model reduced the amount of floating being out of shape, improved degree of accuracy.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, the utility model is a kind of interior clamped-in style vernier caliper detector, mainly comprises two groups of vernier caliper fixed mechanisms and measuring basis assembly, and vernier caliper fixed mechanism relative measurement fiducial is symmetrical arranged;
Wherein vernier caliper fixed mechanism comprise that vernier caliper fixed mechanism comprises slide rail 1, tooth bar fixed mechanism and claw fixed mechanism;
Tooth bar fixed mechanism comprises two relative slide rail 1 symmetrically arranged tooth bar fixed claws 6 in middle part, tooth bar fixed claw 6 is fixed on slide rail 1 by screw symmetry, the top of tooth bar fixed claw 6 is provided with a straight-line groove 5, in the upper side of straight-line groove 5, be provided with a hold-down bolt 2, on the movable end of hold-down bolt 2, be also provided with clamping piece, clamping piece and hold-down bolt 2 are rotationally connected, and hold-down bolt 2 is flexibly connected with fixed claw 4;
Claw fixing structure comprises two symmetrically arranged fixed claws 4 of relative slide rail 1 middle part mirror image, fixed claw 4 is slidably connected with slide rail 1, in fixed claw 4, be processed with open slot 7, open slot 7 is strip, according to the claw profile of vernier caliper, process, the openend of open slot 7 arranges in opposite directions, a fixed claw 4 dorsad side of open slot 7 is also rotatably connected to a housing screw 3, housing screw 3 is flexibly connected by screw thread with the bottom of tooth bar fixed claw 6, and the start direction of housing screw 3 is parallel with straight-line groove 5;
Measuring basis assembly comprises reference block, reference block 9 is cylindrical, at the center of reference block, be provided with columniform through hole, on slide rail 1, be provided with the fixed block 8 of taper, the fixed block 8 of two groups of vernier caliper fixed mechanisms is inserted in the cylindrical hole of reference block, between fixed block 8 outer walls and columniform through hole, is interference fit;
In the time will measuring, the measuring claw of two vernier calipers is snapped into respectively on the both sides of reference block, fixed claw 4 covers are received on measuring claw simultaneously, then with tooth bar fixed mechanism, tooth bar is fixed, screw subsequently housing screw 3, claw is pressed on reference block, now contrast the own size A according to reference block, obtain the registration X of first vernier caliper, the registration of second vernier caliper is Y, if vernier caliper has error, X is not equal to Y, now can judge the coefficient (general A can diminish gradually along with the wearing and tearing of using) that X and Y depart from according to size A, if depart from excessive one vernier caliper, can think the problem vernier caliper that error is larger, can pull down departing from excessive vernier caliper, changing another vernier caliper contrasts again.The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on instructions, must determine its technical scope according to claim scope.
