Description

Press mounting die device of the deep groove ball bearing without crimping type shield

Technical field

The utility model is related to bearing mounting technology field, especially a kind of deep groove ball bearing press-fiting without crimping type shield Die device.

Background technology

Due to deep groove ball bearing while needing to install dust cap, dust cap is compared difficult assembling with outer ring interference fit, used The assembling mode efficiency of hand assembled is low and the unstable easy generation neglected loading phenomenon of quality.And bearing of the prior art is mostly adopted Edge-curled type dust cap is used, edge-curled type dust cap is assembled using a punching press, because this press-fit approach is to dustproof groove and crimping The Geometrical Tolerance Principle of formula dust cap is very high, and being also easy to produce edge-curled type dust cap can not be completely into dustproof groove or entering crimping after groove Formula dust cap is also easy to produce loosening, and the qualification rate of punching press assembling is low, and stress is larger in punching press assembling process, and edge-curled type is dust-proof The inside and outside lasso of lid and bearing easily deforms, and have impact on the running accuracy and service life of bearing.It is contemplated that deep-groove ball Bearing is used without edge-curled type dust cap, for being accomplished by improving press mounting die device of the prior art without edge-curled type dust cap.

Utility model content

The technical problems to be solved in the utility model is：There is provided a kind of deep groove ball bearing for the deficiency for overcoming in the prior art Press mounting die device without crimping type shield.

The utility model solves the technical scheme that its technical problem used：A kind of deep groove ball bearing is without crimping type shield Press mounting die device, the bearing includes being installed between the inside and outside circle of bearing and being only located at the dust cap of bearing side, described Press mounting die device includes upper die and lower die, and the upper mould is the frustum cone structure that bottom has step, the step inner side edge edge There is downwards centering spindle, the external diameter of the centering spindle, which is equal on the internal diameter of bearing, ledge surface, has downward boss, described convex The width of platform is more than or equal to the width for the contact surface that upper mould is contacted with dust cap, and the external diameter of step is more than the internal diameter of bearing outer ring It is described logical and less than the external diameter of bearing outer ring, the lower mould is cylindric for Intermediate Gray through hole, and with the annular groove for accommodating bearing The diameter in hole is equal to the internal diameter of bearing.

Further, the inner peripheral surface of the bearing outer ring is provided with dustproof groove, what the dust cap was contacted with dustproof groove Edge has a circle latex circle.Latex circle is set, and one prevents dust cap from being deformed when press-fiting, and two also produce dustproof groove Raw abrasion.

Further, there is annular groove in the middle of the upper surface of the latex circle.Annular groove is set, is easy to latex Circle is attached on dust cap.

Further, the top of the upper mould has contiguous block, and the contiguous block is connected with equipment upper cylinder device, institute State and pressure warner is installed on air cylinder device.Pressure warner is installed, effect is air pressure mistake proofing, is being set on air cylinder device Standby above to install pressure controller additional, when pressure anomaly (being less than) is in setting, equipment alarm is simultaneously out of service.

Further, the upper mould is screwed with contiguous block.

The beneficial effects of the utility model are：

1. on mould ledge surface on there are downward boss, i.e. confined planes, can control dust cap to push stroke true Protect dust cap installation site；

2. on mould bottom centering spindle, can prevent bearing skew dislocation；

3. increasing warning device, monitoring device atmospheric pressure state, such as air pressure are less than setting equipment will be out of service and carry out Alarm, prevents dust cap to be not installed in place.
