Abstract

The invention relates to the technical field of mechanical processing, and discloses a magnetorheological polishing equipment. The magnetorheological polishing equipment drives a horn and a magnet to perform synchronous reciprocating linear motion, and combines ultrasonic and magnetorheological polishing on the surface of a workpiece. Polishing has the advantages of good controllability, high material removal rate, and no subsurface damage; ultrasonic waves can cause the horn to vibrate at high frequencies, with a vibration frequency as high as 20Khz. Compared with traditional magnetorheological polishing technology, it has greatly improved Polishing efficiency; the high-frequency vibration of the horn causes the magnetorheological polishing fluid to form a flexible polishing head with certain removal capabilities around the horn. The operation is simple, and the composite motion of the workpiece and the flexible polishing head makes the polishing surface more uniform. . This polishing equipment has the advantages of simple structure, compactness, and uniform polishing.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a magnetorheological polishing device. Background technique [0002] Titanium alloy tubes have the characteristics of high pressure resistance and corrosion resistance, and are widely used in aerospace, medical, military and other fields. Restricted by the use environment, the surface roughness requirements inside the pipe fittings are very high. On the one hand, it is to ensure the smooth transportation of gas or liquid in the pipe, to avoid the surge phenomenon caused by the uneven inner surface of the pipe, and on the other hand, to avoid the surface defects caused by the pipe wall. pollution and corrosion, and improve the service life of pipe fittings. Titanium alloy pipes are mainly processed by two processes: hot extrusion by press and cross-rolling perforation. Affected by the processing technology, the surface of the inner wall is often accompanied by surfa...
