Problems solved by technology
[0003] However, the rotation accuracy of the grinding wheel dresser of the machine tool is not high at present, because the two ends of the rotary shaft mainly rely on the conical surface for positioning and rotation, and after repeated friction between the conical surfaces, the contact surface wears out after a period of time, and the accuracy will decrease. Lost, the shape of the trimmed grinding wheel does not meet the process requirements, and the bearing groove processed by this grinding wheel does not meet the process requirements

A new grinding wheel dresser rotary device includes a rotation shaft, a gasket, a bearings a, a housing, a spring, a sleeve, and a bearing b; the bearing a and the bearing b sleeve the outside of the rotation shaft, the housing 4 is arranged on the outside of the bearing a and the bearing b, the inner side of the housing is equipped with a projection, one end of the projection is close to one end of the bearing a; the outer side of the rotation shaft is provided with the sleeve, one end of the sleeve n is close to one end of the bearing b, and the spring is arranged between the projecting portion and the sleeve. The new grinding wheel dresser rotary device is simple in structure, and easy to process, has a significant positive effect on the grinding wheel dresser trimming during the grinding process of the bearing channel, the service life of the new grinding wheel dresser rotary device can be extended, and the accuracy of the trimmed arc is ensured, and the productivity is increased.
Description
technical field [0001] The invention belongs to the field of bearing processing, and in particular relates to a novel turning device of a grinding wheel dresser. Background technique [0002] It is known that the grinding of the bearing groove is a crucial process in the production and processing of the bearing, and the grinding shape of the groove, that is, the groove shape, is one of the key factors affecting the quality of the groove grinding, but The groove shape is not stable in production and processing, and the factor affecting the groove shape is the dressing shape of the grinding wheel, that is, the higher the precision of the grinding wheel dresser on the machine tool, the higher the shape accuracy of the dressing wheel is. [0003] However, the rotation accuracy of the grinding wheel dresser of the machine tool is not high at present, because the two ends of the rotary shaft mainly rely on the conical surface for positioning and rotation, and after repeated fricti...
