[0002] Rollers are important components in various mechanical equipment, playing a supporting and power transmission role, so that the various components in the machine can work together. After production and processing, the rollers need to be polished to improve their surface finish and effectively remove the rough parts and tiny flaws on the roller surface to make its surface smooth, thereby reducing the friction between the roller and other components during operation, improving the overall performance of the roller, and extending its service life.

[0003] When polishing a roller using polishing equipment, after placing the roller on the equipment, the polishing wheel on the polishing machine drives the roller to rotate and drives the roller to move along the equipment to complete the polishing of the roller surface. Since the rotation and movement of the roller are driven by the polishing wheel on the polishing machine using friction transmission, it is easy to make the rotation rate and movement rate uneven, affecting the polishing quality and polishing effect.

Then, according to the specifications of the roller and the polishing requirements, the assembly platform is raised and lowered along the column, and the position of the polishing machine is adjusted so that the polishing wheel of the polishing machine abuts against the roller. When it is running, the driving mechanism drives the mounting chuck to drive the roller to rotate, and the reciprocating cylinder drives the roller to move horizontally, so that the outer surface of the roller is in continuous and comprehensive contact with the polishing machine.
