Description

Tubular workpiece surface machining system Technical Field The invention relates to the field of polishing equipment, in particular to a surface processing system for a tubular workpiece. Background The workpieces such as the tank body of the water storage tank and the pressure tank are generally in a tubular structure, namely, a hollow cylinder is arranged in the middle, and the cylinder is generally fixed in shape by bending a plane plate into the shape of a pipeline and then welding along the axial direction of the pipeline. The ends of the cylinder are welded with side plates (or end caps, etc.) to close the can. The structural design and the processing method enable two types of welding seams to exist on the outer surface of the workpiece, namely, an axial welding seam positioned at the middle cylinder and an annular welding seam positioned at the joint of the side plate and the middle cylinder. To improve the surface quality of the workpiece, these welds need to be polished The outer surface of the workpiece with the structure often has axial welding seams at the middle cylinder and annular welding seams at the connection of the side plates and the middle. And in order to improve the surface quality, the weld joint needs to be polished. However, since there are two different shaped (directional) welds, this requires reversing or secondary clamping of the workpiece during the grinding process to accommodate the grinding requirements of the different welds. This undoubtedly reduces the processing efficiency.
