Description
Technical field
The present invention relates to a kind of bearing inner race raceway superfinishing equipment, especially one kind are surpassed using spiral way
The use method of adjustment of the Superfinishing machine of lappingout processing.
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 with master
Axle rotates together, and the channel location at bearing inner race diametric(al) two ends carries out microstoning with the oilstone of two pieces of different qualities.
Wherein, one block of oilstone carries out screw (angle of oscillation speed omega, point-to-point speed ν synthesizes), oilstone pressure ρ, another piece of oil
Stone carries out oscillating motion (angle of oscillation speed omega).Mode for realizing Lapping Boll processing adopts bearing inner race as shown in Figure 2
Raceway Lapping Boll machine.
In order that having high geometric accuracy, high roughness and low ripple after bearing inner race raceway superfinishing
Degree.It is necessary to make the bearing inner race raceway center of curvature consistent with the swing centre of gyration of oilstone swinging head during superfinishing.I.e. axle
Hold the inner ring raceway center of curvature, the swing centre of gyration of oilstone swinging head (referred to as three together with oilstone arc surface center superposition
Center superposition).If oilstone swings the centre of gyration with bearing inner race raceway center of curvature malalignment error in 0.2-0.35mm
When bearing inner race raceway error in geometrical form can be caused to be increased dramatically, can reach 7-15 micron.Accordingly, it would be desirable to a kind of bearing inner race
The use method of adjustment of raceway Lapping Boll machine, 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.
Content of the invention
The present invention is to provide for a kind of use method of adjustment of bearing inner race raceway Lapping Boll machine, and the method makes in bearing
Enclose the raceway center of curvature, the swing centre of gyration of oilstone swinging head is together with oilstone arc surface center superposition, and ensure oilstone
The swing centre of gyration of swinging head and oilstone arc surface center superposition coaxiality error are less than 2 microns, substantially reduce superfinishing grind plus
Bearing inner ring raceway error in geometrical form after work.
For achieving the above object, the technical scheme is that a kind of using of bearing inner race raceway Lapping Boll machine is adjusted
Adjusting method, comprises the concrete steps that: before adjustment oilstone swinging head position, first with measurer check and correction, oilstone is adjusted to stone swinging head
Swing the centre of gyration, then, unload oilstone swinging head, the bearing inner race needing superfinishing is arranged on bearing inner race rotation
Fixing in driving means and centralizer, replace, with the adjustment support equipped with amesdial, the oilstone swinging head having unloaded and be arranged on sky
Between connecting rod vibrate on the swinging axle of wig-wag, and make the measurement head of amesdial thereon and bearing inner race raceway contact, adjust
Frame forward and backward position adjustments screw rod 2, makes the measurement head of amesdial move along bearing inner race raceway axial direction micro-shifting, and stops at amesdial
At reading minimum, at this moment the vertical axis of swinging axle is overlapped with bearing inner race raceway vertical axis, then gyroscopic pendulum moving axis makes thousand points
The measurement head of table moves along the whole shape face of bearing inner race raceway center cross-sectional, adjusts space connecting-rod simultaneously and vibrates wig-wag
Upper and lower position adjusting screw rod, till the pointer of amesdial swings in the range of 0-0.005mm, now, the level of swinging axle
Axis is overlapped with bearing inner race raceway horizontal axis, and that is, three center be aligneds finish, and finally, unload adjustment support, load onto oilstone pendulum
Dynamic head.
The invention has the beneficial effects as follows: the method can easily make the bearing inner race raceway center of curvature, oilstone swinging head
Swing the centre of gyration together with oilstone arc surface center superposition, and ensure the swing centre of gyration and the oilstone circle of oilstone swinging head
Cambered surface center superposition coaxiality error is less than 2 microns, and after substantially reducing superfinishing, bearing inner ring raceway geometry is missed
Difference, improves bearing inner race raceway superlinishing surface roughness, reduces percent ripple.
