Abstract

The invention discloses a grinding machine abrasive wheel dresser for the convexity of a roller bearing raceway. The dresser comprises a base fixed on a dressing feeding carriage and a diamond pen dressing an abrasive wheel to have an inward concave profile curve, wherein the base is provided with a dressing reciprocating mechanism, an axial elastic moving element and a small plunger pump valve combination element are driven by the reciprocation of the dressing reciprocating mechanism, the axial elastic moving element and the diamond pen are fixed and assembled, the small plunger pump valve combination element is arranged at one side of the dressing reciprocating mechanism and can generate displacement change through a template which leans against and is fixed on the dressing feeding carriage and has a curve profile, hydraulic transfer drives the axial elastic moving element to drive the diamond pen to move, so that the diamond pen obtains a template profile curve moving track reducedin proportion and the abrasive wheel can be dressed to have an inward concave profile curve. The grinding machine abrasive wheel dresser has advantages of simple structure, low cost and convenience in regulation, and the convexity parameters of different specifications can be obtained by replacement of templates.

Description

technical field [0001] The invention relates to the technical field of grinding machine equipment, in particular to a grinding wheel dressing device used in the inner and outer ring raceway grinding machine tools of straight raceway bearings such as cylindrical or tapered roller bearings, specifically roller bearing raceways Wheel dresser for crown grinder. Background technique [0002] The shape of the raceways of bearings such as cylindrical rollers or tapered rollers directly affects the accuracy, performance and service life of the bearings. The bearing is subjected to external force during operation, and the raceway produces elastic deformation, and a large amount of deformation will occur at both ends of the raceway, resulting in stress concentration, which will cause ring-like peeling in a symmetrical position on the circumferential direction of the bearing raceway or roller edge and fail. Therefore, effectively reducing the contact stress at the edge of the raceway...
