As the stainless steel welded pipe continues to move, the grinding assembly 55 can continue to grind and shape each position of the stainless steel welded pipe.

[0021] like Figure 2 As shown, as a preferred embodiment of the present invention, the driving assembly 54 includes: a wheel frame 541, which is fixedly mounted on the inner wall of the support ring 51, and a first power member 542 is mounted on the wheel frame 541, and the output shaft of the first power member 542 is fixedly connected to a driving gear 543, and the driving gear 543 is rotatably arranged in the wheel frame 541; a gear ring 544, which is fixedly mounted on the outer wall of the rotating ring 53 and meshes with the driving gear 543.

[0022] When controlling the rotation of the grinding assembly 55, turn on the first power component 542, which is specifically a motor. The output shaft of the first power component 542 drives the driving gear 543 to rotate in the wheel frame 541. The rotation of the driving gear 543 drives the gear ring 544 and the rotating ring 53 to rotate. The rotation of the rotating ring 53 can drive the grinding assembly 55 to rotate close to the outer surface of the stainless steel welded pipe.
