Abstract
The utility model discloses an abrasive wheel arc trimming device mounted on a numerical control bearing grinding machine, which comprises a frame and a servo motor mounted in the frame. The frame is fixedly connected onto a feeding rack of the numerical control bearing grinding machine, a rotary shaft is vertically arranged in the frame and transversely provided with a mounting hole, an abrasive wheel cutting tool is arranged in the mounting hole, a driving gear is disposed on the upper portion of the mounting hole and meshed with a rack arranged at the top of the abrasive wheel cutting tool which is capable of horizontally sliding in the mounting hole. The abrasive wheel arc trimming device is low in input cost, high in automation level and capable of precisely trimming abraded formed arc abrasive wheels by the aid of an existing numerical control bearing grinding machine, and production cost is reduced.
Description
Technical field
The utility model relates to wheel dresser, especially a kind of abrasive wheel grinding wheel arc trimming device of installing in the numerical control bearing grinder.
Background technology
In the precise finiss process of ball bearing, the ball raceway groove of bearing outer ring inwall is to use moulding arc diamond wheel grinding.The moulding arc diamond wheel cuts with the ball raceway groove of its small sand grains thing to said bearing outer ring inwall, and the sand grains thing is rust or come off gradually, causes the grinding face precision to reduce, and influences the quality of ball bearing.For guaranteeing the grinding accuracy of bearing outer ring inwall ball raceway groove, need in time to change worn out moulding arc diamond wheel, the expensive moulding arc diamond wheel of frequent replacing, production cost strengthens.
The utility model content
The purpose of the utility model is: the abrasive wheel grinding wheel arc trimming device in the numerical control bearing grinder of installing that a kind of input cost is low, automaticity is high is provided; Can utilize existing numerical control bearing grinder; Accurately the worn out moulding arc diamond wheel of finishing reduces production costs.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
A kind of abrasive wheel grinding wheel arc trimming device of installing in the numerical control bearing grinder of the utility model; Comprise frame, be contained in the servomotor in the said frame, said frame is fixedly connected on the feeding frame of numerical control bearing grinder; Vertically be provided with gyroaxis in the frame; Along laterally being provided with installing hole, in said installing hole, be provided with the emery wheel cutting tool on the said gyroaxis, be provided with driven wheel on the top of said installing hole; Through said driven wheel and the engagement that is located at the tooth bar at emery wheel cutting tool top, this emery wheel cutting tool can horizontal slip in said installing hole.
Said emery wheel cutting tool is made up of penholder and the diamond pen that is used for the trimming wheel arc surface that is arranged at this penholder left part.
Said servomotor is electrically connected with the control system of numerical control bearing grinder, and is in transmission connection respectively at gyroaxis and driven wheel through transmission mechanism.
Compared with prior art the beneficial effect of the utility model is: owing to adopt technique scheme, said frame is fixedly connected on the feeding frame of numerical control bearing grinder, vertically is provided with gyroaxis in the frame; Along laterally being provided with installing hole, in said installing hole, be provided with the emery wheel cutting tool on the said gyroaxis, be provided with driven wheel on the top of said installing hole; Through said driven wheel be located at the engagement of the tooth bar at emery wheel cutting tool top, this emery wheel cutting tool can horizontal slip in said installing hole, this structure; The emery wheel cutting tool is loaded on the feeding frame of numerical control bearing grinder, can realize moving forward and backward, and the emery wheel cutting tool is loaded on the gyroaxis; Gyroaxis drives through servomotor; Can realize revolution of 0-130 degree and move left and right, utilize the accurate control of existing numerical control bearing grinder, can make the emery wheel cutting tool finishing point of moulding arc diamond wheel aimed at forever the center of circle of moulding arc diamond wheel; Make the circular arc radian of finishing more accurate; The moulding arc diamond wheel is repeatedly used repeatedly, improve the utilization rate of moulding arc diamond wheel, reduce production costs; Owing to utilized existing numerical control bearing grinder, the utility model input cost is low, automaticity is high.
Description of drawings
Fig. 1 is the structural representation of the utility model;
