[0002] Steel pipe polishing is a surface treatment process used to improve the appearance and surface quality of steel pipes, and also to increase their corrosion resistance, surface smoothness or cleanliness. In the field of automobile manufacturing, special-shaped steel pipes are often used in body frames, chassis and other parts. In order to improve the appearance quality and surface finish of the car body, special-shaped steel pipes need to be polished to ensure that their appearance meets the requirements.

[0003] After searching, the Chinese patent document announcement number: CN217225036U discloses a special-shaped steel pipe polishing device, including an L-shaped bracket, a chuck, a motor and a gearbox, the L-shaped bracket is rotatably mounted with a chuck, the left end of the L-shaped bracket is mounted with a gearbox, and the left end of the gearbox is mounted with a motor, the right end of the gearbox is connected to the chuck through a connecting shaft, the top of the L-shaped bracket is provided with a strip groove, and a screw is rotatably mounted inside the strip groove, a slider is movably mounted on the annular side of the screw, a swing rod is mounted on the top of the slider, and a polishing sheet is mounted at the rear end of the swing rod. The utility model can not only realize the rotation of the nut and the locking of the slider by rotating the rotating rod to pull the magnetic block one and squeeze the magnetic strip, but also facilitate the movement and reset of the magnetic strip through the elastic force of the spring one, and facilitate the movement of the magnetic block one to adsorb and fix the nut through the elastic force of the spring two, and can also facilitate the position of the polishing sheet by adjusting the swing rod through the design of the rotating pin and the torsion spring.

[0004] The beneficial effects of the above patent specification mention that "the rotation of the rotating rod pulls the magnetic block and squeezes the magnetic strip together to achieve the rotation of the nut and the locking of the slider. The rotating rod rotates to squeeze the round rod. The round rod is squeezed and moves downward, driving the magnetic strip to move downward. The magnetic strip moves downward and is adsorbed and fits with the bottom end of the inner wall of the strip groove to achieve the purpose of locking the slider. The rotating rod rotates and pulls the T-shaped round block upward at the same time. The T-shaped round block moves upward and drives the magnetic block to separate from the nut. Because the nut is installed inside the slider through a ball bearing, the rotation of the screw drives the nut to rotate, achieving the purpose of pausing the slider, which facilitates the suspension of the polishing sheet and facilitates the polishing of the local position of the steel pipe."
