Description
Technical field
The utility model belongs to the steel ball press fitting work of technical field of bearings more particularly to a kind of precision corner touching ball bearing
Dress.
Background technique
Do not have lock ball function due to retainer pocket Kong Weizhi pocket hole for the accurate angular contact ball bearing in straight pocket hole,
It is generallyd use when assembling hot pressing and steel ball is sticked to bearing inner race channel with vaseline or butter and is temporarily fixed at retainer
On inner ring, then heats bearing outer ring and carry out hot pressing assembly.Since the adhesive property of vaseline and butter is not strong, for slightly big
The steel ball of any can not be stable be sticked in bear inner ring grooved railway, be easy to fall off, retightened again after falling off, assembly efficiency is extremely low,
And vaseline or butter must be cleaned up after assembling, increased extra workload, spend the time longer.
Summary of the invention
In order to solve the problems, such as background technique, the purpose of the utility model is to provide a kind of precision corners to touch ball bearing
Steel ball press-mounting tool.
In order to realize above-mentioned purpose of utility model, the utility model uses technical solution as described below:
A kind of steel ball press-mounting tool of precision corner touching ball bearing, including pedestal, spring, supporting block and sliding mandrel, branch
Bracer is fixedly connected on base upper surface, and supporting block has axial central through hole, and central through hole is up-small and down-big ladder
Hole, sliding mandrel are fitted in the central through hole of supporting block, and the step surface of annular, sliding are equipped on the periphery of sliding mandrel
The small diameter bore for being located at part and central through hole above step surface on mandrel is equipped with, and sliding mandrel is upper below step surface
Part and the large diameter hole of central through hole are equipped, and axial blind hole is equipped at the center of sliding mandrel lower end surface, is set in blind hole
It is equipped with spring, lower spring end stretches out blind hole and is resisted against on the upper surface of pedestal；The upper end of mandrel is slided equipped with pyramidal
Bulb is filled, fills and is evenly distributed on the circular conical surface in bulb equipped with several sliding slots, generatrix direction of the sliding slot along dress bulb opens up.
Further, the dress bulb is structure as a whole with sliding mandrel.
Further, the hole face of the small diameter bore of the central through hole upper end of supporting block raises upward to form the limit of annular
Portion.
Further, it is evenly distributed on the lower end surface of supporting block equipped with several threaded holes, certainly by soket head cap screw
It is lower and upper being fixedly connected for realization pedestal and supporting block in threaded hole is bolted in after pedestal.
Due to the adoption of the above technical scheme, the utility model has following superiority:
The present apparatus is not required to vaseline or butter stationary balls, save the cost during filling ball；Present apparatus structure is simple,
Design rationally, can be recycled, assembly cost is low；It is easy to operate when use, can one man operation, high production efficiency.

Specific embodiment
The technical solution of the utility model is described in further detail with reference to the accompanying drawings and embodiments.
As shown in Figure 1,2,3, 4, a kind of steel ball press-mounting tool of precision corner touching ball bearing, including pedestal 1, spring 3, branch
Bracer 4 and sliding mandrel 5, are evenly distributed equipped with several threaded holes on the lower end surface of supporting block 4, pass through soket head cap screw 2
It passes through to be bolted in after pedestal from bottom to top and realizes being fixedly connected for pedestal 1 and supporting block 4 in threaded hole；Supporting block 4 has axial
Central through hole, central through hole be up-small and down-big stepped hole, sliding mandrel 5 be fitted in the central through hole of supporting block 4, in cunning
The periphery of moving mandrel 5 is equipped with the step surface of annular, slides part and the central through hole being located above step surface on mandrel 5
Small diameter bore is equipped, and the large diameter hole for sliding the part and central through hole being located at below step surface on mandrel 5 is equipped, in slide cores
It is equipped with axial blind hole at the center of 5 lower end surface of axis, spring 3 is provided in blind hole, 3 lower end of spring stretches out blind hole and is resisted against bottom
On the upper surface of seat 1；The upper end for sliding mandrel 5 is equipped with pyramidal dress bulb, and the dress bulb is integrated with sliding mandrel 5
Structure is filled and is evenly distributed on the circular conical surface in bulb equipped with several sliding slots 11, and generatrix direction of the sliding slot 11 along dress bulb opens up.
The hole face of the small diameter bore of the central through hole upper end of supporting block 4 raises upward to form the limiting section 10 of annular.
In specific application, pedestal, supporting block, spring and sliding mandrel are installed in place first, spring 3 has centainly at this time
