Description

Technical Field

[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 flat surface. It is a modification process on the surface of a workpiece using polishing tools and abrasive particles or other polishing media; polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but is intended to obtain a smooth surface or mirror gloss, and is sometimes used to eliminate gloss (matte).

[0003] Chinese patent application No. 201520805692.7 discloses a steel pipe inner wall polishing device, including a frame mechanism and a polishing mechanism, the frame mechanism includes a support arm, a pulley frame, a guide rail, a walking pulley, a telescopic sleeve, an adjustment member and a cantilever, the support arm includes at least two, the support arm is fixed on the lifting mechanism, the pulley frame is fixedly connected to the support arm through a perforation, and walking pulleys are respectively provided at both ends of the pulley frame; the polishing mechanism includes a support seat, a motor, a buffer, a polishing wheel, a grinding wheel ring and a polishing brush, and the support seat is connected to the head of the cantilever;

[0004] The above-mentioned steel pipe inner wall polishing equipment polishes the inner wall of the steel pipe by means of polishing parts such as a polishing wheel and a polishing brush; however, the above-mentioned steel pipe inner wall polishing equipment does not have parts for fixing the steel pipe. When the polishing parts such as a polishing wheel and a polishing brush of the steel pipe inner wall polishing equipment polish the inner wall of the steel pipe, the steel pipe will be subjected to a large friction force. Under the influence of the friction force, the steel pipe will rotate synchronously with the polishing wheel and the polishing brush, thereby causing the steel pipe inner wall polishing work to be unable to proceed normally.
