Abstract
The invention discloses an internal support special for superfinishing a bearing ring. The internal support comprises a support body, a working outer ring, a double-sleeve bearing and a locknut, wherein the outer surface of the working outer ring is a cylindrical support surface, and is flexibly contacted with the inner diameter of a workpiece; and the outer diameter of the double-sleeve bearing and the working outer ring are in interference fit, and the inner diameter of the double-sleeve bearing and a support shaft are in transitional fit. By adopting the structure, the fixed-point permanent support in the prior art is improved into the transposition rotating support, the permanence is changed into rotation, the sliding is changed into rolling, and the roughness of the inner diameter of the inner ring is reduced through rolling positioning of the double-sleeve bearing and the flexible contact of the outer ring and the workpiece, the friction between the internal support and the inner diameter of the inner ring can be radically stopped, the collision between the bearing and the internal support is reduced, and the appearance quality of the bearing is improved.
Description
Technical field
The present invention relates to a kind of bearing machining special tooling, relate in particular to a kind of special-purpose inner support of microstoning optimal design.
Background technology
For a long time, homemade taper roll bearing exists the uneven quality problems of bearing bore diameter aberration.That is: taper roll bearing ubiquity internal diameter blackout phenomenon, the taper roll bearing internal diameter aberration of current domestic Production of bearing manufacturer production is serious, though do not influence dimensional accuracy and running accuracy, but have a strong impact on the presentation quality of product, split bearing producer has descended the very big time on this problem, as: change the fulcrum material that supports, change materials such as pottery or nylon by original carbide alloy into, but just phenomenon alleviates, and can not deal with problems fully.
Summary of the invention
Purpose of the present invention overcomes in the present conical roller bearing ring processing exactly, because the problem that supporter and workpiece contact mode exist, cause the appearance qualities such as internal diameter aberration, a kind of internal support special for superfinishing bearing ring is provided, former fixed point fixed support is improved to the transposition rotary support, become and be fixed as rotation, become and slide to rolling, by double sets of bearings scroll positioning in addition outer ring and workpiece flexible contact, reduce inner ring internal diameter roughness, can stop the friction of inner support and inner ring internal diameter fully, reduce colliding with of bearing and inner support, improve the bearing presentation quality.
The objective of the invention is to be achieved through the following technical solutions, this internal support special for superfinishing bearing ring comprises supporter, work outer ring, double sets of bearings, locking nut, the outer surface of described work outer ring is the pillar support face, described pillar support face and workpiece diameter are flexible contact, described double sets of bearings external diameter and work outer ring interference fit, the internal diameter of described double sets of bearings and back shaft interference fits.
Preferably, described work outer ring is a polyamide material.
Preferably, described pair of cover bearing is deep groove ball bearing.
Preferably, described double sets of bearings external diameter is the 0.05-0.08 millimeter with the value of interference fit of work outer ring.
Preferred, described double sets of bearings external diameter is 0.06 millimeter with the value of interference fit of work outer ring.
During work, utilize the head of a bed rotating band part of starting building to rotate, in utilizing workpiece to rotate again to drive support works outer ring and workpiece synchronously to rolling, thereby avoided friction between workpiece and support.Adopt high-quality low noise deep groove ball bearing to connect and support and the outer ring interference fit, improve and support outer ring running accuracy and contact rigidity.
Beneficial effect of the present invention
1, by the fixed point sliding support of workpiece in the prior art and supporter, changing into the rolling of work outer ring cylindricality supporting surface supports, interior support and workpiece contact area have been optimized, make workpiece when the high speed load running, owing to of the effect of work outer ring cylindricality supporting surface with workpiece " the flexible contact ", make workpiece evenly stressed when microstoning, improve the superfinish quality
2, be rolling friction owing to become sliding friction, prolonged the service life of inner support, avoided bearing bore diameter aberration phenomenon, thereby improved the presentation quality of bearing.
3, adopt high-quality low noise deep groove ball bearing to connect and support and the outer ring interference fit, improve and support outer ring running accuracy and contact rigidity, improve its integrated load performance.

Fig. 2 is the schematic diagram of prior art inner support
Among the figure: 1, supporter 2, work outer ring 3, cylindricality supporting surface 4, two cover deep groove ball bearing 5, locking nut 6, fulcrum
The specific embodiment
As shown in Figure 1, this internal support special for superfinishing bearing ring comprises supporter 1, work outer ring 2, two cover deep groove ball bearing 4, locking nut 5, work outer ring 2 is polyamide material, the outer surface of work outer ring 2 is pillar support face 3, pillar support face 3 is flexible contact with workpiece diameter, two cover deep groove ball bearing 4 external diameters are 0.06 millimeter with work outer ring value of interference fit, the internal diameter of two cover deep groove ball bearings 4 and back shaft interference fits.
During work, utilize the head of a bed rotate to drive workpiece and rotate, the recycling workpiece rotates and drives inner support work outer ring 2 and workpiece synchronously to rolling, thereby has avoided the friction between workpiece and support.Adopt high-quality low noise deep groove ball bearing 4 to connect and support and work outer ring 2 interference fit, improve and support outer ring running accuracy and contact rigidity.
Fig. 2 shows the inner support of prior art, and supporter contacts with workpiece diameter by the work outer ring.
