The device comprises an inner magnetic pole driving device, an outer magnetic pole driving device and an axial feeding device; the pipe fitting is clamped on a machine tool, an inner magnetic pole is placed inside the pipe fitting, the inner magnetic pole driving device is connected with the inner magnetic pole, and the inner magnetic pole driving device drives the inner magnetic pole to vibrate in the axial direction of the pipe fitting; an outer magnetic pole is arranged outside the pipe fitting, the outer magnetic pole is connected with the outer magnetic pole driving device, and the outer magnetic pole driving device drives the outer magnetic pole to rotate around the axis of the outer magnetic pole; and the axial feeding device is connected with the inner magnetic pole driving device and the outer magnetic pole driving device and drives the inner magnetic pole driving device and the outer magnetic pole driving device tofeed synchronously along the axis of the pipe fitting. The magnetic grinding and polishing device and method for the inner surface and the outer surface of the pipe fitting have the advantages of simple structure and convenient operation, can realize the composite motion of the magnetic poles, improve the processing efficiency and improve the grinding and polishing quality of the inner surface and the outer surface of the pipe fitting.

Description

technical field [0001] The invention relates to the technical field of magnetic grinding and polishing of inner and outer surfaces of pipe fittings, in particular to a magnetic grinding and polishing device and method for inner and outer surfaces of pipe fittings. Background technique [0002] The commonly used processing method of pipe fittings is stamping forming, which inevitably produces many defects such as cracks and burrs on the inner and outer surfaces of the workpiece. At present, manual methods, electrolytic methods, ultrasonic methods, etc. are commonly used to eliminate defects. The manual method is time-consuming and laborious and requires the processor to have a certain technical level; the electrolysis method causes the vicinity of the workpiece burr to be electrolyzed, the surface will lose its original luster, and even affect the dimensional accuracy; for the burr visible to the naked eye, if the bond strength is large , Ultrasonic method does not work at a...

Problems solved by technology

However, due to the simple movement of the magnetic poles, the grinding efficiency is low, the grinding track is single, and new magnetic grinding textures are easily formed, thereby affecting the grinding quality of the workpiece surface
