Abstract

The invention relates to a grinding wheel arc corrector. The outer contour of a correcting grinding wheel is made completely consistent with that of a bearing inner race to be machined through a revolving platform and two mobile platforms, besides, only one reference surface needs to be machined, and then the correcting grinding wheel can grind two rollaway nests of the bearing inner race at the same time. Therefore, the problems that when two reference surfaces are used for grinding the two rollaway nests, the bottom diameter of double rollaway nests of ground finished grooves, the curvature radius of the double rollaway nests and the positions of the rollaway nests can not be guaranteed, production requirements can not be met, and the overall quality of a self-aligning roller bearing is seriously affected are solved.

Description

A kind of corrector of grinding wheel circular arc
Technical field
The present invention relates to a kind of grinding equipment, specifically a kind of corrector of grinding wheel circular arc.
Background technology
Rolling bearing is that the axle of running and the sliding friction between axle bed are 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, is therefore carried out self-aligning roller bearing extremely important in bearing industry is produced.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 the semi arch design of two symmetries, 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 all are 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 object of the present invention is to provide a kind of corrector of grinding wheel circular arc, by emery wheel is revised, making to revise emery wheel can carry out grinding to two raceways of bearing inner race simultaneously, solves the not accurate problem with two datum level grindings.
For achieving the above object, the invention provides a kind of corrector of grinding wheel circular arc, comprise emery wheel, 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 the 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 the 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 all are electrically connected and accept its control with the 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 controls and to carry out gyration by the emery wheel electric rotating machine, and described emery wheel electric rotating machine is electrically connected and accepts its control with the numerical control device implementation.
The diamond pen that utilization is arranged on the revolution bent axle is made the circular arc corrector, emery wheel is modified to the two arc structures identical with inside race, then removes the grinding bearing inner ring raceway with the correction emery wheel; Adopt two mobile motors below revolving dial, utilize digital control system to control two-axle interlocking, the very fast realization revised.
Further improvement of the present invention 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, receive signal reaction quick.
Further improvement of the present invention 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.
Characteristics of the present invention are that two raceways are carried out to grinding simultaneously, in production process in front, 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 fully at the bottom of two raceways of finished product of grinding, effect is very good.

Drawing reference numeral: self-aligning roller bearing inner ring 1, turning motor 4, longitudinal mobile motor 5, transverse mobile motor 6, slew gear 7, longitudinal moving mechanism 8, transverse moving mechanism 9, revolving dial 10, transverse shifting platform 11, diamond pen 12, revolution bent axle 13, vertically move platform 14, emery wheel 15, feed mechanism 16, feeding platform 17, emery wheel electric rotating machine 18.
The specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is described in further detail, this embodiment is only for explaining the present invention, to this, practical protection domain does not form restriction.
Referring to accompanying drawing 1, during grinding self-aligning roller bearing inner ring 1, be that grinding be take the axis of self-aligning roller bearing inner ring 1 and is the symmetrical outline be comprised of two radius R, need to make the outline of emery wheel 15 adaptive with it, two reference axis that must be able to realize diamond pen 12 control that simultaneously links, it not only requires the Origin And Destination coordinate position of moving component, and requires to control speed and the displacement of whole process every bit.
By reference to the accompanying drawings 2, the present invention proposes a kind of corrector of grinding wheel circular arc, comprise emery wheel 15, described emery wheel 15 is placed on a feeding platform, and described feeding platform one end is equipped with feed mechanism 16, and the other end connects an interlock controlling organization.Described interlock controlling organization comprises revolving dial 10, passes through fixedly single-revolution bent axle 13 of two slew gears 7 on described revolving dial 10, and described revolution bent axle 13 inner ring outer side center are equipped with a form of a stroke or a combination of strokes mould, and revolving dial 10 is driven and carried out gyration by turning motor 4; Described revolving dial 10 belows are equipped with transverse shifting platform 11 and vertically move platform 14, described transverse shifting platform 11 with vertically move platform 14 and be fixedly connected with motor with longitudinal moving mechanism (8) by transverse moving mechanism (9) respectively, do corresponding the movement and pass through respectively transverse mobile motor 6 with longitudinal mobile motor 5, and described longitudinal mobile motor 5, transverse mobile motor 6 and turning motor 4 all are electrically connected and accept its control with the numerical control device implementation.Described form of a stroke or a combination of strokes mould is diamond pen 12, 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.
