Detailed Description

The utility model will be described in further detail with reference to the drawings and the detailed description.

As shown in fig. 2-4, this embodiment provides a caliper spring detection tool, which comprises a base 1, a detection table 2, a simulation block 3 and a compactor 4, wherein the detection table 2 is arranged in the middle of the base 1, two compactors 4 are respectively arranged on the left side and the right side of the detection table 2, and the simulation block 3 is used for being clamped between four elastic clamping hooks 51 above a caliper spring 5 shown in fig. 1 so as to simulate the assembly form of the spring. The action structure of the compactor 4 is the same as that of a conventional quick clamp, and comprises a mounting seat 41, a pressing arm 42, a linkage arm 43, an operation arm 44 and a pressing piece 45, wherein the pressing arm 42 and the linkage arm 43 are respectively and rotatably connected to the mounting seat 41, the operation arm 44, the pressing arm 42 and the linkage arm 43 are respectively and rotatably connected, the pressing piece 45 is arranged on the pressing arm 42, and the pressing arm 42 is pulled to rotate along a rotating connection point of the pressing arm 42 and the mounting seat 41 by rotating the operation arm 44, so that the pressing piece 45 swings to realize pressing or lifting actions, and the structure has the function of keeping a pressing state. The two compactors 4 press down the simulation block 3, so that the caliper spring 5 to be tested is extruded between the detection table 2 and the simulation block 3 to be in a compressed state for detection.

Specifically, as shown in fig. 1, the support point of the lower end of the caliper spring is two support legs 52 far apart, that is, the portion between the two support legs 52 does not contact the detection table 2, so that in consideration of cost and weight, we design the detection table as two separated tables 21 to provide sufficient support positions for the two support legs, respectively.

In addition, when the spring receives the compression force, there is a possibility of displacement, so in order to avoid this situation, two guide rods 211 are respectively arranged on the two sub-platforms 21, and corresponding guide holes 31 are arranged on the analog block 3, so as to ensure that the horizontal position of the analog block is stable, i.e. the spring (center) cannot be displaced, during the pressing process, thereby ensuring the stability of the compression form of the spring. Meanwhile, in order to ensure that the position of the compactor 4 acting on the analog block 3 is accurate, so as to ensure the balance of the downward pressing acting force, the springs need to be accurately placed, therefore, by arranging the reference barrier strips 212 on the same side of the two sub-tables 21, one edge of the springs is placed along the reference barrier strips, the position accuracy of placing the springs each time can be ensured, and of course, when the guide structure collides with the reference barrier strips, the assembling position between the analog block and the springs can be adjusted, so that the requirements of two structures can be met simultaneously.

In order to control the accuracy of the compression amount of the spring, two pressing positioning rods 213 are provided on each of the sub-tables 21, for limiting the pressing amplitude of the analog block, that is, controlling the compression amount of the spring. Meanwhile, in order to facilitate adjustment of the height of the pressing positioning rod 213 so as to meet different detection requirements, the pressing positioning rod 213 is in threaded connection with the sub-table 21, and up-down adjustment can be achieved by rotating the pressing positioning rod so as to change the maximum pressing amplitude of the analog block, namely, the compression amount of the spring.

Correspondingly, the pressing piece 45 of the pressing device 4 needs to have an up-down adjusting function, so that the pressing piece 45 specifically includes a threaded rod 451, a pressing head 452 disposed at the lower end of the threaded rod 451, and two positioning nuts 453 disposed on the threaded rod 451, and the pressing arm 42 is provided with a bar-shaped adjusting hole 421, the threaded rod 451 passes through the adjusting hole 421, and the fastening installation is achieved by using the upper positioning nut 453 and the lower positioning nut 453; and the up-down position of the threaded rod 451, that is, the up-down position of the pressing head 452, can be adjusted by up-down adjustment of the two positioning nuts 453 to fit the pressing positioning rod 213 while maintaining an appropriate pressing force. In addition, the position of the threaded rod 451 can be adjusted along the length direction of the adjusting hole 421 to adjust the acting point of the pressing head 452 on the analog block 3, so as to ensure the stability of the pressing force. Further, the pressing piece 25 further includes two limiting gaskets 454 disposed between the positioning nut 453 and the pressing arm 42, and limiting portions 4541 configured on two opposite sides of the pressing arm and cooperating with the two sides of the pressing arm are disposed on two sides of the limiting gaskets 454, so as to avoid rotation of the limiting gaskets, and thus rotation of the screw in a positioning state is avoided.

And then the operation arm of the compactor is rotated to enable the pressing arm to swing, the pressing piece presses down the simulation block, and the spring is compressed. And then, the corresponding size index of the compressed spring can be detected, and the detection is finished by only loosening the compactor and taking down the spring.

The foregoing is merely a preferred embodiment of the present utility model, which is based on one implementation of the overall concept of the present utility model, and the scope of the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the technical scope of the present utility model should be covered by the scope of the present utility model.
