technical field

The invention relates to the field of inspection tools, in particular to a detection device for a driven disk shock absorber.

Background technique

Now the production of driven plate shock absorbers for automobile clutches is widely produced by punching machines, and the precision requirements for workpieces are very high in production. In particular, the most difficult thing to guarantee for stamped parts is the flatness requirement, and for automobile clutch driven plate shock absorbers There are very few special inspection tools for flatness.

The existing patent 205537396 discloses a special inspection tool for the driven plate shock absorber of automobile clutch, which consists of a dial indicator, a table frame, a guide rail, a detection platform, a shaft sleeve, a workpiece, a positioning block, a positioning column, a positioning pin and other auxiliary mechanisms The device can only detect the size and position of four holes at a time. Although the dial indicator can slide on the guide rail, it can only slide in a straight line, so the measured area only includes the rectangle that the dial indicator passes through in a straight line. The area does not completely cover the entire shock absorber, and to measure the flatness of all positions on the shock absorber, it is necessary to disassemble and install the shock absorber again, which is more cumbersome.
