Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment, in particular to a grinding equipment for pipe fittings. Background Art

[0002] There are tubular structure accessories on the auto parts. During the manufacturing process of tubular auto parts, the end face of the pipe mouth of the pipe fitting needs to be polished to make the pipe mouth smoother to facilitate the assembly of the pipe fitting.

[0003] Traditional pipe grinding is done manually using a grinding wheel grinder. When operating, the grinder can be turned on first to drive the grinding wheel to rotate at high speed. Then the worker can hold the workpiece in contact with the high-speed rotating grinding wheel. The grinding wheel will continuously rub the surface of the workpiece, causing the surface of the workpiece to peel off through friction and shearing to achieve the purpose of grinding. In this way, the pipe fittings need to be fixed by hand, which poses a great safety hazard. In addition, operational errors are prone to occur when the hands shake, affecting the grinding quality of the pipe fittings.

[0004] Therefore, grinding is currently carried out by combining a grinding wheel grinder with a clamping tool. During operation, the workpiece can be clamped and fixed by a clamp first, and then the staff can push the grinder close to the workpiece until the grinding wheel contacts the workpiece to achieve grinding. After grinding, the clamp needs to be opened manually to release the workpiece and manually unload the material. Since the workpiece is clamped in advance during the operation, the workpiece will not be displaced due to shaking during the grinding process, and it is relatively stable, thereby reducing operating errors, being safer, and improving the grinding quality of pipe fittings.
