Thereafter, the front cover shell 24 is plugged into the U-shaped frame 2 to protect the grinding disc 22, the tripod 9 and other parts.

[0033] Working principle: By starting the electric push rod 8 to push the tripod 9 inward, the gear can be clamped by the pressure head 11 on the tripod 9. When clamping, the suction cup 10 on the tripod 9 can firmly suck the gear, which enhances the stability of the tripod 9 clamping the gear, making it less likely for the gear to shake during grinding, reducing the probability of errors in grinding, and improving the accuracy of gear grinding.
