Description

Automatic grinding device for metal parts Technical Field

[0001] The utility model relates to the technical field of parts processing, in particular to an automatic grinding device for metal parts. Background Art

[0002] Machining mainly refers to the process of changing the external dimensions or mechanical properties of parts through mechanical equipment. According to the processing method, it can be divided into cutting, pressure processing and grinding. Grinding is a type of surface modification technology, which is mainly used to obtain a specific surface roughness of the workpiece. Mechanical parts need to be polished using a grinding device. In order to improve the stability of the parts during grinding, the parts need to be fixed.

[0003] For example, patent publication number CN218312686U discloses a "mechanical parts grinding device." A worker manually rotates a turntable forward or backward, driving a threaded rod forward or backward. This in turn moves the right clamping block toward or away from the left clamping block, allowing the two clamping blocks to clamp the part. However, this method can only secure square metal parts and is incapable of positioning shafts. Furthermore, after securing, the metal parts cannot be automatically aligned, making grinding more difficult. Utility Model Content
