Description

Technical Field

[0001] The utility model relates to a stainless steel pipe inner wall polishing device, in particular to a stainless steel pipe inner wall polishing device, belonging to the technical field of polishing. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface.

[0003] When polishing stainless steel pipe fittings, the polishing equipment drives the polishing head to rotate so that the polishing head fits against the inner wall of the stainless steel pipe fittings and polishes them to make the inner wall of the stainless steel pipe smooth and flat.

[0004] In the prior art, when polishing stainless steel pipe fittings, the stainless steel pipe fittings are placed on left and right support rollers, the stainless steel pipe fittings are squeezed and fixed by an extrusion wheel, and then the polishing head is adjusted to fit the inner wall of the stainless steel pipe fittings. The stainless steel pipe fittings and the polishing head are rotated for polishing. However, when polishing, the polishing head needs to be adjusted to squeeze the stainless steel pipe fittings. When the flatness of the inner wall of the stainless steel pipe fittings is poor, the position of the polishing head needs to be continuously adjusted to ensure that the inner wall of the stainless steel pipe fittings is completely flat, which affects the polishing efficiency. Therefore, we propose a stainless steel pipe inner wall polishing device. Utility Model Content
