Vibrating magnetic needle and magnetic particle composite grinding device

Abstract

The invention relates to a vibrating magnetic needle and magnetic particle composite grinding device which comprises a machine base, a machine cover, a grinding mechanism, a vibrating mechanism and agrabbing mechanism. The machine cover is arranged above the machine base; the grinding mechanism is arranged in the machine base and the machine cover; the grabbing mechanism is arranged on the top part of the machine cover; and the vibrating mechanism arranged on the outer side of the machine base is connected with the grinding mechanism. The grinding mechanism comprises a grinding barrel, a magnetic pole disc and a rotary motor; the grinding barrel is arranged above an upper plane of the machine base; the magnetic pole disc is arranged under the upper plane of the machine base and is drivenby the rotary motor so as to rotate; the magnetic pole disc comprises a rotary plate and magnetic pole pillars; a plurality of magnetic pole pillars are arranged on the rotary plate; and magnetic poles of each two adjacent magnetic pole pillars are opposite. According to the vibrating needle and magnetic particle composite grinding device provided by the invention, a rotating magnetic field is formed in the grinding barrel, magnetic needles and magnetic abrasive particles are subjected to the vibration composite movement of the magnetic field and the grinding barrel, and workpieces and mixed abrasive materials form high-speed and multi-angle impact, so that bulges, edges, burs and the like produced after complicated workpiece processing can be high-efficiently removed, and the grinding efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of polishing, in particular to a vibrating magnetic needle composite magnetic particle grinding device. Background technique [0002] With the continuous advancement of science and technology, straight pipes and bent pipes of various materials and diameters, complex parts such as 3D printing, and workpieces that need to be processed on designated parts are constantly being used in machinery, aviation, medicine and other industries. In these fields, the requirements for surface quality and material removal are getting higher and higher. The traditional magnetic needle grinding method uses the workpiece and the magnetic needle to be placed in the grinding barrel, and the magnetic pole plate under the barrel rotates to make the non-magnetic workpiece and the rotating The magnetic needle forms a lag, so as to realize the surface processing of the workpiece and remove its surface material. This processing method...

AI Technical Summary

Problems solved by technology

This processing method is inefficient and the complexity of the processed parts is limited, especially the designated part of the workpiece cannot be processed. Since the magnetic needle is only subjected to rotational motion during processing, the magnetic needle collision motion is single and the efficiency is low.
