The polishing structure 4 is fixedly installed on one side of the base plate 101.

[0051] Specifically, the outer diameter size of the stainless steel pipe to be polished is adjusted by sliding the dynamic limiting side plate 201 on the upper surface of the base plate 101, and the distance between the dynamic limiting side plate 201 and the fixed limiting side plate 301 is adjusted to adapt to the actual size of the pipe. During work, the pipe is inserted from the end of the base plate 101 without the polishing structure 4, and the pipe is driven to move by the conveying belt 102. During the movement, the limiting wheels 202 abut against one side surface of the pipe, and the auxiliary balls 303 abut against the other side surface of the pipe to limit the position of the pipe in the front-rear direction. It should be noted that the maximum diameter of the pipe cannot exceed the radius of the limiting wheel 202. When the limiting wheel 202 abuts against the pipe, the force applied is downward at an angle to provide certain limitation in the up-down direction of the pipe. The limiting wheels 202 rotate synchronously to rub the pipe to rotate during the movement of the pipe, so that the position of the pipe to be polished is changed at any time when the polishing structure 4 polishes the side surface of the pipe.
