Abstract

The invention discloses an apparatus suitable for efficient fitting of a non-magnetic conductive workpiece inner surface, wherein the apparatus provided herein is capable of effectively fitting an inner hole of a non-magnetic conductive workpiece, an inner surface of a multi-hole round pipe, an inner surface of a small pipe, an inner surface of a square pipe and an inner surface of a multi-group small pipe; the apparatus provided herein comprises a main shaft motor, a main shaft, a clamp disc, a workpiece, coils, magnetic poles, a magnetic conductor, a magnetism grinding material, a tail base, a base, a spacer, a support and a varnished wire; the main shaft motor and a main shaft are fixed on the support; the varnished wire is wound into two coils; the workpiece is covered by the two coils; two magnetic poles are provided; the two magnetic pole are connected by the magnetic conductor; and the spacer, the support and the tail base are fixed on a base plate through bolts. According to the invention, the roughness value of the inner surface after being fitted is reduced; burrs are removed; and the apparatus provided herein also has the advantages of improving the residual stress on the surface and improving the fatigue strength of the surface.

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...
