Abstract

The invention discloses a hydromagnetic grinding device of ceramic ball surface, which comprises the following parts: case, magnet assembly, floating board, bearing, rotary-shaped tray, guide ring, abrasion wheel and ceramic ball placing space, wherein the magnet assembly is composed of each permanent magnet with cross N and S polarity arrangement on the bottom of case, which connects the floating board through elastic connection part in the internal wall of case; the bearing is fixed on the floating board with rotary-shaped tray on the top of bearing; the guide ring is set in the case; the abrasion wheel is set on the top of case to be driven, whose lower surface, internal side of guide ring and conical face of rotary-shaped tray form the ceramic ball placing space; the magnetic fluid is charged in the inner cavity of case.

Description

technical field [0001] The invention relates to surface finishing equipment, in particular to ceramic ball surface grinding equipment, in particular to a magnetic fluid grinding device for ceramic ball surface grinding. Background technique [0002] In recent years, with the advancement of science and technology, the use environment and conditions of rolling bearings have become more and more diverse. At present, ceramic ball bearings with excellent properties such as wear resistance, heat resistance, and corrosion resistance are being developed, and silicon nitride (Si 3 N 4 ) The study of the load characteristics of the base ceramic material shows that silicon nitride is very suitable as a rolling bearing material. However, due to the poor processing technology of ceramic materials, the efficiency of processing ceramic balls with traditional grinding methods is low and the processing cost is high. [0003] Magnetic fluid is a colloidal suspension formed by dispersing na...
