[0002] In the mechanical structure of the loader, the pin shaft is a standardized fastener, mainly used to connect various parts of the loader to form a hinge structure. The pin shaft is connected through the frame and the tool connecting head of the loader to realize reliable connection of each part. The function of the grinding device is to polish the rough outer surface of the pin shaft to ensure the surface precision of the pin shaft and improve the wear resistance of the pin shaft.

The front and rear end faces of the base are fixedly connected with a support plate through bolts. The linear array of cleaning holes in the sliding groove constitutes an automatic cleaning structure for residues in the sliding groove. During use, when the mounting seat moves, the sliding protrusions on the mounting seat can clean the residues from the cleaning holes. This solves the problem that the residues generated during grinding of the double-end pin shaft easily fall into the sliding track, causing severe abrasion and jamming of the sliding structure during sliding. This requires disassembly for maintenance or replacement, reducing processing efficiency and increasing maintenance cost. In addition, the clamping structure is prone to looseness during grinding, which may lead to reduced grinding accuracy.
