Abstract

The invention discloses a rolling-bearing magneto-rheological polishing device for high-accuracy ceramic balls. The rolling-bearing magneto-rheological polishing device comprises an inner-ring barrel(8), an outer-ring barrel (1) and a ceramic ball retainer (3) arranged between the inner-ring barrel and the outer-ring barrel (1), wherein a ceramic ball accommodating space (5) is formed in the ceramic ball retainer (3), a plurality of annular magnets (7) are arranged in the inner-ring barrel (8), location blocks (4) are arranged among the annular magnets (7), and the location blocks (4) are uniformly arranged in the inner-ring barrel (8); and the ceramic ball retainer (3) is connected with the inner-ring barrel (8) through a bolt, and concentrically arranged with the inner-ring barrel (8),and the space between the outer-ring barrel (1) and the inner-ring barrel (8) is filled with a magneto-rheological polishing liquid (2). In combination with magneto-rheological flexible polishing, thepolishing device disclosed by the invention is capable of efficiently obtaining high-quality smooth ceramic ball surfaces with both high dimension accuracy and shape accuracy.

Description

technical field [0001] The invention relates to a ceramic ball grinding and polishing device and a polishing method thereof, in particular to a processing device for precision grinding and polishing of high-precision ceramic balls in high-speed, high-precision ceramic ball bearings, which belongs to the processing technology of high-precision spherical parts. Background technique [0002] High-precision ceramic balls are widely used in ball bearings and are the key parts. At the same time, ceramic balls play a very important role in precision equipment such as roundness meters, bearings, gyroscopes, and precision measuring instruments. very important position. Precision ceramic balls have extremely high requirements on spherical deviation, ball diameter variation and surface roughness. These parameters directly affect the technical indicators of ball bearings such as motion accuracy, noise and life, and then affect the performance of equipment and instruments. [0003] Com...
