Description

Technical Field

[0001] The utility model relates to the technical field of sinker processing, and particularly relates to a chamfering mechanism for sinker processing. Background Art

[0002] After the sinker is processed and formed, chamfering processing needs to be carried out on its periphery. However, since the sinker is a special-shaped part, the existing chamfering devices cannot process it. Therefore, it is often processed one by one by manually pressing one hand and holding a grinding chamfering machine with the other hand. This processing method has a relatively low processing efficiency. Moreover, due to the small volume of the sinker, there are safety hazards in the processing method of pressing one hand and holding a grinding chamfering machine with the other hand. Therefore, it is particularly important to design a chamfering mechanism for sinker processing to solve the above problems. Summary of the Invention

Through the three chamfering grinding discs arranged, three sinkers in the three grinding stations can be chamfered simultaneously, greatly improving the processing efficiency.
