The sliding groove 27 is a curved surface structure, and the distance from the middle part of the curved surface to the two sides of the curved surface to the surface of the clamping plate 24 is gradually reduced, so that when the shaft part is fixed to rotate, the rubber pad 25 is connected with the shaft more tightly, and the shaft part is prevented from rotating.
The working principle is as follows: firstly, the clamping device for detecting the strength of the automobile shaft parts is installed and used at the position, and the clamping device for detecting the strength of the automobile shaft parts is used according to the following operation modes:
according to the figures 1-10, the length of the shaft part to be detected is observed, and then the distance between the clamping tables 2 is adjusted by sliding the clamping tables 2 on the supporting seat 1;
after the distance between the clamping tables 2 is adjusted, the shaft parts penetrate through 2 clamping tables 2, and then the shifting rod 8 is driven to rotate through the sleeve 9, so that the rotating ring 7 is driven to rotate;
when the rotating ring 7 rotates, the second extrusion block 15 on the inner side can be driven to move, so that the support rod 16 is extruded gradually;
when the lower end of the support rod 16 slides on the second extrusion block 15, the connecting teeth 20 slide on the positioning teeth 21, so that the reverse rotation of the rotating ring 7 can be avoided;
when the support rod 16 is extruded by the second extrusion block 15, the compression spring 29 arranged between the support rod 16 and the inner side of the through hole is compressed, so that the second extrusion block has elastic potential energy for resetting;
the supporting rod 16 is extruded by the second extrusion block 15, so that the clamping plates 24 can be close to each other, and then the supporting rod is contacted with the shaft parts through the rubber pads 25 on the surfaces of the sliding pieces 30 on the clamping plates 24, so that the shaft parts can be clamped and fixed conveniently;
then, the strength of the shaft parts can be detected through a torque force testing machine;
in the detection process, the shaft part has a rotating trend, and the shaft part drives the rubber pad 25 to also have a rotating trend, so that the sliding part 30 has a trend of moving in the sliding groove 27, but because the distance from the middle part of the sliding groove 27 to the two sides of the axis of the through groove 17 is gradually reduced, when the sliding part 30 slides in the sliding groove 27, the sliding part 30 can gradually approach the shaft part, so that the rubber pad 25 is in closer contact with the shaft part, the shaft part is prevented from rotating, and the stable strength detection of the shaft part is facilitated;
after the shaft part is detected to be finished, the supporting disc 3 is rotated, the first extrusion block 4 on the supporting disc 3 extrudes the pressure bearing rod 5, so that the mounting ring 14 is driven to move, the rotating ring 7 and the sliding block 13 synchronously move until the connecting teeth 20 and the positioning teeth 21 are completely separated, and then the shifting lever 8 can be reversely pushed, so that the clamping of the shaft part is released;
finally, the support plate 3 is rotated reversely, so that the first pressing block 4 on the support plate 3 gradually reduces the pressing on the pressure rod 5, thereby the sliding block 13 is reset under the action of the compression spring 29, so that the mounting ring 14 and the rotating ring 7 are reset, and what is not described in detail in this specification belongs to the prior art known by those skilled in the art.
