Stainless steel pipes are an environmentally friendly pipe with advantages such as heat resistance, wear resistance, and corrosion resistance. They are often widely used in various fields. Stainless steel pipes are divided into seamed steel pipes and seamless steel pipes. After the seamless stainless steel pipes are formed and cut, they need to be ground and polished by a stainless steel pipe polishing machine to make the surface of the stainless steel pipe smooth and flat. The automatic polishing machine is a fully automatic surface polishing equipment for workpieces. Its working principle is to drive the polishing head to rotate at high speed through a motor, so that the polishing head drives the polishing auxiliary materials to fully contact the object to be polished. It is suitable for fully automatic polishing of metal workpieces, such as surface gloss and burr removal. This type of equipment is relatively simple to operate, with low operator skill requirements, which can improve production efficiency, reduce labor intensity, save production costs, improve product quality, and reduce product quality differences.

[0003] The existing device mainly polishes the outer wall of the steel pipe by fitting an arc-shaped polishing plate to the outer wall of the steel pipe. The existing technology is similar to a reciprocating automatic polishing device and a polishing method for stainless steel pipe processing. The structure of patent number CN113458959A includes a working platform and a stainless steel pipe body, the stainless steel pipe body is fixedly arranged on the working platform, and a polishing mechanism is arranged outside the stainless steel pipe body. In the present invention, the structure of the existing polishing device is improved, and the improved polishing device adopts an assembled structure, which can realize the convenient installation of the stainless steel pipe, so that in the actual polishing process, it can not only have the effect of convenient operation, but also improve the polishing efficiency. However, there are still areas that can be optimized in the device.

[0004] The existing device mainly drives the polishing component to polish the outer wall of the steel pipe through a reciprocating transmission component, which makes it difficult for some devices to drive the polishing machine to rotate and move along the outer wall of the steel pipe, so as to facilitate the polishing machine to continuously and comprehensively polish the outer wall of the steel pipe. Secondly, the moving path of some polishing machines is fixed, which makes it difficult for some devices to adjust the number of turns of the spiral path of the polishing machine according to the roughness of the outer wall of the steel pipe, thereby causing some devices to waste resources due to excessive polishing. Finally, some devices are mainly equipped with corresponding arc polishing plates according to the specifications of the steel pipe, which makes it difficult for some polishing components to fully fit on the outer walls of steel pipes of different specifications, thereby causing some devices to find it difficult to comprehensively polish the outer wall of the steel pipe body, reducing the working efficiency and practicality of the device.
