Deep groove ball bearing outer ring groove grinder grinding wheel dresser

Abstract

The invention discloses a grinding wheel dresser of an outer ring raceway grinder for deep groove ball bearings. The grinding wheel dresser comprises a sliding seat, an upper bracket glidingly connected below the sliding seat, a coarse-adjusting screw connected between the sliding seat and the upper bracket, a lower bracket arranged below the upper bracket, a fine adjustment device connected between the upper bracket and the lower bracket, a positioning rack detachably connected to one side of the sliding seat, a diamond stylus connected onto the lower bracket, a curvature standard block connected onto the positioning rack and opposite to the nib of the diamond stylus as well as a dial indicator connected onto the positioning rack. The curvature of the dresser can be directly and accurately set and measured; the diamond stylus can be accurately mounted in place once when mounted and replaced for the first time; the curvature of the diamond stylus is not required to be adjusted through repeated trail grinding of ferrules.

Description

technical field [0001] The invention belongs to the field of bearing processing machinery, and in particular relates to a grinding wheel dresser for a deep groove ball bearing outer ring groove grinder. Background technique [0002] combine figure 2 As shown, the distance between the diamond tip and the trimmer cylinder rotation axis (that is, the arc radius R of the diamond tip’s trimming and swinging action, referred to as the curvature of the diamond pen or the curvature of the trimmer) cannot be directly measured and positioned. Very inconvenient. Only rely on the dresser to dress the grinding wheel, and then use the grinding wheel to try to grind the workpiece groove, measure the curvature of the workpiece groove, and indirectly know the curvature of the diamond. Then adjust the position of the diamond, trim the grinding wheel, and try grinding the workpiece. Repeat this several times until the curvature is qualified before formal processing can begin. [0003] When ...

Problems solved by technology

waste time

[0005] The adjustment of the curvature of the groove is not accurate, not timely, and the fluctuation range is large, which will have a certain impact on the subsequent ultra-finishing of the raceway

[0006] Since the position of the diamond pen cannot be accurately marked, when the diamond pen is replaced, it is easy to cause the position to be lost or the curvature to change

waste time, affect efficiency
