Description
Technical field
The invention belongs to bearing ring processing technique field, especially relevant with a kind of thrust ball bearing ring face raceway groove methods of refining.
Background technology
The end face raceway groove of thrust ball bearing lasso is circular arc raceway groove, and end face raceway groove is circular arc line with the intersection of the longitudinal cross-section crossing ferrule central line.End face raceway groove, need through grinding to improve raceway groove precision after machining is shaped.The existing grinding machine for the grinding of thrust ball bearing ring face raceway groove, its layout is all adopt workpiece spindle device to be fixed on lathe bed end face, dresser is arranged at the position away from work spindle, grinding wheel spindle is by X axle, Y axle intersects stacked feed mechanism and drives and move on X axle and Y direction of principal axis, realize the contact grinding of emery wheel and lasso and withdrawing to move to dresser position and carry out crushing, such grinding machine makes emery wheel withdrawing far away to the distance of dresser, the non-cutting time taken is longer, thus reduction production efficiency, and the stacked feed mechanism that intersects makes feed accuracy easily produce larger accumulated error, thus reduction grinding accuracy, in order to improve the defect of above-mentioned existence, the applicant proposes a kind of thrust ball bearing ring face raceway groove method for grinding, workpiece is clamped by magnetic chuck chuck, and by work spindle driven rotary, forming grinding wheel is High Rotation Speed under grinding wheel spindle drives, and the incision end face raceway groove that advances under servo-drive, wheel dressing mechanism is arranged on emery wheel straight line withdrawing path, realize processing of advancing, straight line retreats crushing, improve crushing precision and production efficiency, but such method for grinding still exists defective for the precision bearing lasso that required precision is higher, due to emery wheel employing is symmetrical arc-shaped outer surface plate-like forming grinding wheel, the shaping bus of forming grinding wheel is that the center of circle is positioned at grinding wheel spindle to the circular arc on Central Symmetry face, grinding wheel spindle to workpiece spindle to vertical, emery wheel radial feed vertical cut incision raceway groove, emery wheel is mainly by radial and circumferential load, and due to ring raceways rotation, radius r inside raceway groove is less than outer radius R, linear velocity when then lasso rotates inside raceway groove is less than outside, contact with raceway groove bottom of trench, groove bottom line speed is not maximum, described linear velocity will not be mated, affect the form accuracy in outside in raceway groove, and then make the precision of bearing ring not reach high-accuracy requirement.
Summary of the invention
When object of the present invention is intended to overcome existing thrust ball bearing ring face raceway groove grinding, in raceway groove, the form accuracy in outside is not very high defect, provides the thrust ball bearing ring face raceway groove methods of refining that a kind of ring face channel shape precision is good.
For this reason, the present invention is by the following technical solutions: thrust ball bearing ring face raceway groove methods of refining, it is characterized in that, the lasso of thrust ball bearing with center line transversely shape clamped by the magnetic chuck chuck on work spindle, grinding knife tool adopts deflection arc-shaped outer surface plate-like forming grinding wheel, the center of circle off-axis of the deflection circular arc molding bus of forming grinding wheel is to Central Symmetry face, the deflection arc surface of forming grinding wheel is as cutwork face, lasso is driven with himself center line as pivot rotates by work spindle, the axis angle in an acute angle of axis of workpiece and grinding wheel spindle is also in the same plane, emery wheel High Rotation Speed makes the cutwork face radial feed of emery wheel cut sth. askew into raceway groove, make grinding speed maximum and channel wire speed maximum Corresponding matching, the minimum place of grinding speed and channel wire speed minimum place Corresponding matching, formed soon to soon, slow in slow differential compensation, emery wheel is subject to axis, radial direction and circumferential load, carry out accurate grinding, dresser is arranged at the side in emery wheel straight line withdrawing path, the finishing pen of dresser carries out circular arc swinging motion, the nib track of finishing pen deflects indent arc corresponding to the shaping bus of arc surface in forming grinding wheel outer surface, the cutwork face of emery wheel outer surface and the Stylus contact of finishing pen when emery wheel straight line retreats, during finishing rotation, the cutwork face on emery wheel is repaired, realize emery wheel advance processing, straight line retreats crushing, decrease crushing holding time, and while the crushing of emery wheel withdrawing, the bearing ring machined is reclaimed, send into next bearing ring to be processed, improve production efficiency.
The present invention can reach following beneficial effect: by being arranged to grinding wheel spindle to angle in an acute angle by workpiece spindle, the outer surface of plate-like forming grinding wheel is arranged to deflect circular arc, raceway groove processing is carried out to ring face, realize the cutting circle cambered surface of emery wheel and raceway groove arc surface and form linear velocity soon to soon, slow in slow differential compensation, carry out micro cutting, ensure the form accuracy in outside in ring raceways, realize accurate grinding, reach the required precision of precision bearing lasso, dresser is set by the side of the straight line reverse paths at emery wheel simultaneously, realize processing of advancing, straight line retreats crushing, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is principle schematic of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
