[0002] Stainless steel pipe is a long steel strip with a hollow cross-section and no seams around it. It is a steel pipe that is resistant to corrosion by weak corrosive media such as air, steam, and water, and chemically corrosive media such as acids, alkalis, and salts. The usual way to polish stainless steel pipes is mechanical polishing, where a throwing rod is inserted into the pipe to drive a flap wheel or a homemade abrasive belt wheel to rotate at high speed, and polishing is performed along with the rotation of the steel pipe itself, while the throwing rod is slowly moved forward while rotating.

[0003] At present, when polishing the inner wall of a stainless steel pipe, it is not possible to accurately adjust according to the diameter of the stainless steel pipe, so that different polishing wheels need to be replaced for polishing. Although the inner wall of stainless steel pipes of different diameters can be polished after replacing the polishing wheel, the polishing efficiency is greatly reduced due to the complexity of replacement and the need to customize matching polishing wheels, which seriously affects the production and processing of stainless steel pipes.

[0027] The polishing mechanism 2 includes a telescopic sleeve 21, a plug-in slot 22 is provided inside the telescopic sleeve 21, a telescopic rod 23 is plugged inside the plug-in slot 22, one end of the telescopic rod 23 is connected to a support plate 24, a motor bracket 25 is installed on one side of the support plate 24, a rotating motor 26 is installed inside the motor bracket 25, an output end of the rotating motor 26 is connected to a rotating shaft 27 extending from the other side of the support plate 24, and one end of the rotating shaft 27 is sleeved with a polishing wheel 28;

The support plate 24 can facilitate the installation of the rotating motor 26 through the motor bracket 25 to ensure stability during the polishing process. The rotating motor 26 drives the rotating shaft 27 to drive the polishing wheel 28 at one end to rotate, so as to extend into the interior of the stainless steel pipe to polish it.

[0029] In order to facilitate the adjustment of the thickness of different steel pipe walls during polishing, a plug-in column 29 is also connected to one end of the telescopic rod 23, and an adjustment groove 211 is opened on the surface of the support plate 24. One end of the plug-in column 29 inserted into the adjusting groove 211 is screwed with a limiting bolt 210. The adjusting groove 211 opened on the surface of the support plate 24 can be adjusted to the position of the plug-in column 29, and it can be locked and fixed to the surface of the support plate 24 by the limiting bolt 210.

[0030] As an improvement of the above technical solution, a driving mechanism for driving the telescopic rod 23 to telescope and adjust is arranged at one end of the telescopic sleeve 21, which can be freely adjusted inward and outward when polishing the inside of the stainless steel pipe to ensure the polishing efficiency.
