Abstract

The invention discloses a magnetic grinding device suitable for smoothing the inner surface of a non-magnetic workpiece, capable of efficiently finishing the inner hole of the non-magnetic workpiece, the inner surface of a porous circular tube, the inner surface of a thin tube, the inner surface of a square tube, and the inner surfaces of multiple groups of thin tubes. The ground is smooth. The device includes: a main shaft motor, a main shaft, a chuck, a workpiece, a coil, a magnetic pole, a magnetizer, a magnetic abrasive, a tailstock, a base, a pad, a support and an enameled wire, and the main shaft motor and the main shaft are fixed on the support; The enameled wire is wound into two coils, and the two coils wrap the workpiece; the two magnetic poles are connected through a magnetic conductor; the pad, support and tailstock are fixed on the bottom plate by bolts. The invention reduces the roughness value of the inner surface after finishing and removes burrs, and the invention also has the advantages of improving surface residual stress, increasing surface fatigue strength and the like.

Description

technical field [0001] The invention relates to a smoothing device for polishing and deburring the inner surface, in particular to a magnetic grinding device suitable for smoothing the inner surface of a non-magnetic workpiece. Background technique [0002] With the development of manufacturing technology, the requirements for the inner surface quality of pipe fittings are getting higher and higher in hydraulic, biomedical, nuclear industry, aviation and other fields. In hydraulic pipelines and components, slight burrs or roughness values ​​on the inner wall surface will affect the stability and transmission efficiency of liquid transmission, which will increase the maintenance frequency of hydraulic systems, reduce reliability, and even lead to early damage to hydraulic components. Thus affecting the overall performance; in addition, the presence of burrs on the inner wall will also pollute the purity of the internal transmission liquid; the micro-cracks on the inner surfac...
