[0002] The support roller is an important component in the rolling mill. Its main function is to support the working roller or the intermediate roller to prevent the working roller from bending and deforming during the rolling process. The support roller mainly includes a roller body and a connecting shaft arranged on both sides of the roller body. When the connecting shaft itself is manufactured and connected to the roller body, the butt joints must be welded to ensure the stability of the entire support roller structure. After the connecting shaft is welded and fixed, a weld scar will be left at the weld seam. The weld scar will affect the flatness of the support roller surface, and the welding joint is very easy to oxidize and rust, so the weld scar needs to be polished and cleaned. At present, manual polishing is generally used during the polishing process, that is, the support roller is placed on a rotatable device, and the support roller is driven to rotate by the device, and the worker uses a grinder to polish the weld scar. Such polishing work requires workers to cooperate with the rotation frequency of the rotating equipment to perform the grinding operation.
