[0028] The working principle is as follows: The workpiece is placed on the transfer inclined rack 2 and can move smoothly as the previous workpiece is transferred. During the transfer, the first motor 6 works, the first lead screw 4 rotates, and the slide 5 slides to approach the workpiece. Then, the limit rod 10 is controlled to move by the pick-and-place cylinder 9. The limit rod 10 passes through the inner side of the workpiece from the area where the transfer groove 3 is located.

The support fixed shaft 21 on the positioning mechanism releases the fixation of the outer side of the workpiece. Through radial adjustment, the support fixed shaft 21 is transferred to the inner side of the workpiece to support and fix the workpiece from the inner side. Then the electromagnetic sliding clamp rod 27 releases the clamping of the outer side of the workpiece, and by adjusting the radial position of the grinding wheel 34, the outer side of the workpiece is processed.

[0031] After the processing is completed, the clamping mounting frame 43 on the side of the workpiece moves, that is, the moving electric cylinder 42 controls the clamping mounting frame 43 to move so that the workpiece is located inside the clamping mounting frame 43.
