Through through-hole is equipped in platform, skewed slot is uniformly provided on the rotary table outer wall, the tightening axle passes through through-hole from rotary table side, then
It can be locked nut check in optical axis end.
Preferably, the skewed slot face contact on the inner surface and rotary table of the tensioning hoof.
Preferably, the width and skewed slot of the tensioning hoof front end are of same size.
Be using the beneficial effect of above technical scheme: the rolling bearing inner ring or outer ring grinding attachment will commonly be put down
Key is mounted in the keyway on tightening axle outer wall, and then tightening axle is inserted into through-hole, and is connect with optical axis by general flat key,
Then then rolling bearing inner ring or outer snare are gradually tightened locking nut by spanner, make to tighten outside grinding roller
Axis pushes tensioning hoof along skewed slot toward the big end motion of rotary table by terminal pad, until locking nut is twisted it is motionless until, be tensioned at this time
Hoof driving grinding roller and rolling bearing inner ring or outer ring inner wall are tensioned, and then optical axis is clamped on clamping device, then will
Whole device is moved along lathe guide rail toward three chucking chuck end, so that the rolling bearing inner ring being tensioned or outer ring is entered three and is grabbed card
It in disk, and being clamped, then starts lathe spindle, main shaft is rotated by three chucking chuck with rolling bearing inner ring or outer ring,
After lathe spindle rotates a fixing turn, parking realizes the tension type grinding of rolling bearing inner ring or outer ring inner wall, and uses
Multiple grinding rollers will not reduce the concentricity between the cylindricity of inner wall and inner wall and outer wall, ensure that rolling after grinding
The machining accuracy of bearing.
Skewed slot face contact on the inner surface and rotary table of the tensioning hoof, the width and skewed slot width of the tensioning hoof front end
Identical, anti-rotation cutting force is strong, guarantees the stability of tensioning hoof tensioning.
