Abstract

The invention relates to a bearing ring grinding equal-high rotary table, which comprises a driving motor fixed on one side of the top end face of a chassis of the table, wherein the output shaft of the driving motor is fixed with a driving wheel; a bearing block is fixed on the other side of the top end face of the chassis of the table; the top end part of the bearing block is fixed with a bearing end cover; a bearing is arranged in the bearing block; a rotating spindle is arranged in the bearing block rotationally through the bearing; the bottom end part of the rotating spindle is fixed with a driven wheel; a synchronous belt is arranged on the driving wheel and the driven wheel; the top end part of the rotating spindle is fixed with a sucker connecting bottom plate; a distance is spaced between the bottom end face of the sucker connecting bottom plate and the top end face of the bearing end cover; and a permanent magnet sucker is fixed on the sucker connecting bottom plate. The bearing ring grinding equal-high rotary table can realize equal-high inner and outer rings of the bearing, and achieve the effects of coping the protrusion of the bearing and realizing equal height; and the coping operation is simple and the dimension is easy to control.

Description

technical field [0001] The invention relates to a bearing processing equipment, in particular to a bearing ring grinding contour rotary workbench. Background technique [0002] Bearing width tolerance, according to GB / T307.1 standard, such as 6204 bearings, width tolerance is 14 0 / -0.12. Grinding tolerance is 14 0 / -0.25. Grinding tolerance, the difference between the inner and outer rings is 0.25mm, and the existing double-face grinder and surface grinder can meet the process requirements of the parts. The precision requirements for bearings used in precision machine tools are relatively high, and the height difference between the inner and outer rings of the bearings is required to be no more than 0.002, which cannot be met by using the current double-end grinding machine. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a bearing that can realize the contour of the inner and outer ri...
