Furthermore, the driving unit 103 can be a steering gear or a servo motor, which can drive the rack structure 102 to move back and forth (the driving unit 103 can also be a cylinder or a hydraulic cylinder, which directly drives the rack structure 102 to move along the slide rail), and then the outer ring portion 301 of the transmission gear 30 is rotated, so that the power frame 40 and the rotating shaft 20 installed on the outer ring portion 301 are rotated synchronously, so that the rotating shaft 20 and the power frame 40 can be linked to achieve the effect of grinding the workpiece with high efficiency and high quality.

[0045] like Figure 6 As shown, the transmission gear 30 in this embodiment is a gear with a bearing in the middle, so that the transmission gear 30 is divided into an annular ring structure of the inner ring part 302, the outer ring part 301 has an annular structure of outer ring teeth, and the middle part is connected by a bearing. Therefore, the power frame 40 can be bolted to the outer ring part 301, and the convex ring 201 on the rotating shaft 20 is bolted to the power frame 40 to achieve the purpose of synchronous rotation with the outer ring part 301. Then the inner ring part 302 is locked on the frame body 10 to complete the fixed installation.
