[0035] The reciprocating grinding mechanism is installed on the frame a1, and the reciprocating grinding mechanism includes a reciprocating cylinder 16, a connecting frame b17, two connecting frames a11 and two groups of friction parts. The two groups of friction parts are arranged above the transmission belt a3, and there is a spacing between the two groups of friction parts.

At this time, the workpiece flips 180 degrees, and the original bottom surface flips upward, and the polishing of the last surface of the workpiece is realized by the set rotating polishing component b.
