Description

Technical Field

[0001] This utility model relates to the field of plastic parts processing technology, and in particular to a fixing structure for a plastic parts grinding fixture. Background Technology

[0002] Grinding is an important step in the processing of plastic parts. It can not only remove defects on the surface of plastic parts, but also improve the appearance quality and surface smoothness of plastic parts. In the current outsourced processing of plastic parts, the connection and fixing methods mainly rely on screw locking technology.

[0003] Specifically, the screw locking method requires a screw to be installed at each fixing point, which greatly increases the complexity of assembly. To prevent plastic parts from shifting or falling off, the screws need to be precisely aligned and tightened one by one. This step usually relies heavily on manual operation and is also cumbersome during disassembly and replacement. Furthermore, loose or missing screws may affect the polishing quality or even damage the plastic parts. Utility Model Content
