Abstract

The invention relates to the technical field of machining, and discloses magneto-rheological polishing equipment. The magneto-rheological polishing equipment drives a variable amplitude rod and a magnet to do reciprocating rectilinear motion synchronously, ultrasonic waves and magneto-rheological polishing are combined for polishing the surface of a workpiece, and the magneto-rheological polishingequipment has the advantages of being good in controllability, high in material removal rate and free of sub-surface damage; the ultrasonic waves enable the variable amplitude rod to generate high-frequency vibration, the vibration frequency is up to 20 Khz, and compared with a traditional magneto-rheological polishing technology, the polishing efficiency is greatly improved; and the high-frequency vibration of the variable amplitude rod enables the magneto-rheological polishing solution to form flexible polishing heads with certain removal capacity around the variable amplitude rod, the operation is simple, and the composite motion of the workpiece and the flexible polishing heads enables the uniformity of the polishing surface to be better. The polishing equipment has the advantages ofbeing simple and compact in structure, uniform in polishing and the like.

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...
