Plane magnetic grinding machining assembly line and machining method for inner surface of elbow

Abstract

The invention relates to plane magnetic grinding machining assembly line and machining method for an inner surface of a elbow. The assembly line is characterized in that a feeding station, a machiningstation and a discharging station are connected through a plurality of conveying belts, and grinding material filling devices are arranged on the two sides of the side, close to the machining station, of a feeding conveying belt, and grinding material filling rotary magnetic discs are arranged at the bottom of part, below grinding material discharging ports at the bottoms of the grinding materialfilling devices, of the feeding conveying belt; and the machining station is provided with a plurality of magnetic grinding machines and two mechanical arms; the tail end of a discharging conveying belt is also provided with a stainless steel wire mesh conveying belt and an grinding material collecting conveying belt, the grinding material collecting conveying belt is arranged below the stainlesssteel wire mesh conveying belt, and a grinding material collecting rotary magnetic disc is arranged at the bottom of the grinding material collecting conveying belt. According to the assembly line and the method, grinding and polishing of the inner wall of the elbows with irregular cross sections, the inner wall of the elbows with variable diameters and the inner wall of the welded elbows is realized, the line production of magnetic grinding machining on the inner surface of the elbow is also realized, so that the batch machining of workpieces is facilitated, and the production efficiency isimproved.

Description

technical field [0001] The invention relates to the technical field of magnetic grinding processing, in particular to a magnetic grinding processing line and a processing method for the inner surface of a planar elbow. Background technique [0002] Bends are often used in the industrial, medical and aviation fields, and the inner wall of the bend is required to be smooth and clean, free of cracks, processed textures and weld residues. However, the traditional processing technology is difficult to realize the processing of the inner surface of the elbow, especially the inner surface polishing treatment of the cast reducing elbow and the welding reducing elbow. [0003] In recent years, the polishing of the inner surface of the elbow has been achieved through the magnetic grinding process. Since the magnetic force lines can penetrate the workpiece like X-rays, the abrasive can be adsorbed on the inner surface of the workpiece, thereby realizing the processing of the inner cav...
