Abstract
The utility model relates to a dresser for grinding an abrasion wheel arc. Through one revolving platform and two moving platforms, the outer contour of a dressing abrasion wheel and the outer contour of a bearing inner ring to be machined can be completely coincident, and only one reference plane is needed. Thus, the dressing abrasion wheel can grind two roller paths of the bearing inner ring simultaneously, and the problems that bottom diameters of double roller paths, radii of curvatures of the double roller paths and roller path positions of grinded finished channels can not be guaranteed, production requirements can not be met, the overall quality of self-aligning roller bearings is seriously influenced when two reference planes are used for grinding the two roller paths are solved.
Description
Technical field
The utility model relates to a kind of grinding equipment, specifically a kind of corrector of grinding wheel circular arc.
Background technology
Rolling bearing is that the sliding friction between the axle of running and axle bed is become to rolling friction, thereby reduces the mechanical organ of a kind of precision of friction loss.Wherein self-aligning roller bearing, in occupation of 70 percent share in bearing industry is produced, is therefore carried out self-aligning roller bearing extremely important.In process of production, the quality of mill processing directly affects total quality and the life-span of bearing.Because the inner ring raceway of self-aligning roller bearing is two symmetrical semi arches designs, if with conventional method for grinding, just can not carry out grinding to two raceways simultaneously, can only first grind a raceway and change again another raceway of face grinding, this will do two datum levels, to processing, bring very large difficulty.Because the depth of parallelism of two datum levels starting is difficult to guarantee, so two raceways with these two datum level grindings, at the bottom of two raceways of grinding finished product raceway groove out, footpath, the radius of curvature of two raceways, raceway position are all difficult to guarantee, do not reach Production requirement, have a strong impact on the total quality of self-aligning roller bearing.
Summary of the invention
The purpose of this utility model is to provide a kind of corrector of grinding wheel circular arc, and by emery wheel is revised, making to revise emery wheel can carry out grinding to two of bearing inner race raceways simultaneously, solves the not accurate problem with two datum level grindings.
For achieving the above object, the utility model provides a kind of corrector of grinding wheel circular arc, comprises emery wheel, and described emery wheel is placed on a feeding platform, and described feeding platform one end is equipped with feed mechanism, and the other end connects an interlock controlling organization; Described interlock controlling organization comprises revolving dial, is equipped with single-revolution bent axle on described revolving dial, and described revolution bent axle inner ring outer side center is equipped with a form of a stroke or a combination of strokes mould, and revolving dial is driven and carried out gyration by turning motor; Described revolving dial below is equipped with transverse shifting platform and vertically moves platform, described transverse shifting platform and vertically move platform and do respectively corresponding mobilely by transverse mobile motor and longitudinal mobile motor, and described longitudinal mobile motor, transverse mobile motor and turning motor are all electrically connected and accept its control with numerical control device implementation; When static, the centerline of described emery wheel and form of a stroke or a combination of strokes mould is on same straight line, and emery wheel controlled and to be carried out gyration by emery wheel electric rotating machine, and described emery wheel electric rotating machine is electrically connected and accepts its control with numerical control device implementation.
The diamond pen that utilization is arranged on revolution bent axle is made circular arc corrector, emery wheel is modified to the two arc structures identical with inside race, then removes grinding bearing inner ring raceway with correction emery wheel; Below revolving dial, adopt two mobile motors, utilize digital control system to control two-axle interlocking, very fast realization revised.
Further improvement of the utility model is: described turning motor, longitudinal mobile motor, emery wheel electric rotating machine and transverse mobile motor are servomotor, make control rate, and positional precision is all very accurate, receives signal reaction quick.
Further improvement of the utility model is: described form of a stroke or a combination of strokes mould is diamond pen, and wearability is good, and intensity is high, easy to use, does not need tough mill and overhauls, and guarantees precision and the surface smoothness of processing parts.
Feature of the present utility model is that two raceways are carried out to grinding simultaneously, in production process above, only need do a datum level, just can carry out two raceway grindings together, through repeatedly practice, out footpath, the radius of curvature of two raceways, the requirement that raceway position reaches production completely at the bottom of two raceways of finished product of grinding, effect is very good.
