Description
Technical field
The present invention relates to a kind of bearing inner race raceway superfinishing equipment, especially a kind of Use Adjustment method adopting spiral way to carry out the Superfinishing machine of superfinishing.
Background technology
The mode of Lapping Boll processing, as shown in Figure 1, bearing inner race is fixed on the main shaft of Lapping Boll machine, and rotates with main shaft, and the oilstone of two pieces of different qualities of the channel location at bearing inner race diametric(al) two ends carries out microstoning.Wherein, one block of oilstone carries out screw (angle of oscillation speed omega, point-to-point speed ν synthesizes), and oilstone pressure Ρ, another block oilstone carries out oscillating motion (angle of oscillation speed omega).For the mode realizing Lapping Boll processing adopts bearing inner race raceway Lapping Boll machine as shown in Figure 2.
After making bearing inner race raceway superfinishing, there is high geometric accuracy, high roughness and low percent ripple.During superfinishing, the bearing inner race raceway center of curvature must be made consistent with the swing centre of gyration of oilstone swinging head.Namely the swing centre of gyration of the bearing inner race raceway center of curvature, oilstone swinging head (is called for short three center superpositions) together with oilstone arc surface center superposition.If oilstone swings the centre of gyration and bearing inner race raceway center of curvature malalignment error can cause bearing inner race raceway error in geometrical form sharply to increase when 0.2-0.35mm, 7-15 micron can be reached.Therefore, need a kind of Use Adjustment method of bearing inner race raceway Lapping Boll machine, make the swing centre of gyration of the bearing inner race raceway center of curvature, oilstone swinging head together with oilstone arc surface center superposition.
Summary of the invention
The present invention is a kind of Use Adjustment method that will provide bearing inner race raceway Lapping Boll machine, the method makes the swing centre of gyration of the bearing inner race raceway center of curvature, oilstone swinging head together with oilstone arc surface center superposition, and ensure that the swing centre of gyration of oilstone swinging head and oilstone arc surface center superposition coaxiality error are less than 2 microns, greatly reduce superfinishing rear bearing inner ring raceway error in geometrical form.
For achieving the above object, technical scheme of the present invention is: a kind of Use Adjustment method of bearing inner race raceway Lapping Boll machine, concrete steps are: before adjustment oilstone swinging head position, first with measurer check and correction, oilstone is adjusted to the swing centre of gyration of stone swinging head, then, unload oilstone swinging head, fixing needing the bearing inner race of superfinishing to be arranged on bearing inner race rotating driving device and centralizer, replacing with the adjusting pole that amesdial is housed the oilstone swinging head unloaded is arranged on the swinging axle of space connecting-rod vibration wig-wag, and make gage outfit and the bearing inner race raceway contact of the amesdial on it, before regulating support, rear position adjustments screw rod 2, make the gage outfit of amesdial along the axially micro-movement of bearing inner race raceway, and stop at the minimum place of amesdial reading, at this moment the vertical axis of swinging axle and bearing inner race raceway vertical axis coincide, gyroscopic pendulum moving axis makes the gage outfit of amesdial move along the whole shape face of bearing inner race raceway center cross-sectional again, regulate the upper of space connecting-rod vibration wig-wag simultaneously, upper/lower positions adjusting screw(rod), till the pointer of amesdial swings within the scope of 0-0.005mm, now, the horizontal axis of swinging axle overlaps with bearing inner race raceway horizontal axis, namely three centers are aimed at complete, finally, unload adjusting pole, load onto oilstone swinging head.
The invention has the beneficial effects as follows: the method can make the swing centre of gyration of the bearing inner race raceway center of curvature, oilstone swinging head easily together with oilstone arc surface center superposition, and ensure that the swing centre of gyration of oilstone swinging head and oilstone arc surface center superposition coaxiality error are less than 2 microns, greatly can reduce superfinishing rear bearing inner ring raceway error in geometrical form, improve bearing inner race raceway superlinishing surface roughness, reduce percent ripple.
