Description

Shell bearing press mounting fixture

Technical field

The utility model is related to a kind of fixture, especially a kind of shell bearing press mounting fixture.

Background technology

Currently, bearing press mounting is usually using distance controlling compression distance and pressing force between tooling and equipment, the two it Between be firm docking without automatically correcting and buffer.There is unstability to part and equipment, so that equipment is worked overloadingly for a long time and be easy to make Forming apparatus failure-frequency increases, and part is be easy to cause since the lengthy pressure effect of excess load can increase inside parts stress It part crack and bursts apart.

Utility model content

For overcome the deficiencies in the prior art, a kind of press fitting stabilization is provided, accurate positioning, press-loading device and component are harmless Shell bearing press mounting fixture.

The purpose of utility model is achieved through the following technical solutions：A kind of shell bearing press mounting fixture, including fixture bottom Seat is equipped with limit shaft in the fixture base, compressed spring and shell locating piece is cased on the limit shaft, in the limit The upper end of position axis has been connected by screw bearing outer ring positioning core axle, and circular cone is equipped in the upper end of the bearing outer ring positioning core axle Roller bearing outer ring.

The utility model has the characteristics that compared with prior art：

Simple in structure, easy to use, part is in and automatically corrects state during being pressed using telescopic spring performance guarantee, Press fitting process part qualification rate is improved, the failure rate of equipment is reduced.

Description of the drawings：

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the stereogram of the utility model；

Figure label：1- fixture bases, 2- limit shafts, 3- compressed springs, 4- shell locating pieces, 5- bearing outer ring locating cores Axis, 6- taper roll bearings outer ring.

Specific implementation mode：

In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further It is described in detail, which is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.

As Fig. 1-2 shows a kind of specific implementation mode of shell bearing press mounting fixture of the utility model：Including fixture bottom Seat 1 is equipped with limit shaft 2 in the fixture base 1, compressed spring 3 and shell locating piece 4 is cased on the limit shaft 2, The upper end of the limit shaft 2 has been connected by screw bearing outer ring positioning core axle 5, in the upper of the bearing outer ring positioning core axle 5 End is equipped with taper roll bearing outer ring 6.

The utility model is simple in structure, easy to use, and part is in certainly during being pressed using telescopic spring performance guarantee Dynamic correcting state, secondly shell axially position, part are in suspension self-centering to process of press in bearing outer ring axially position first Automatic rebounding is exited bearing outer ring locating core by state, the effect part when being depressed into dead point equipment and exiting due to compressed spring Axis, the utility model are conducive to improve press fitting process part qualification rate, reduce the failure rate of equipment.

The another statement of applicant, the utility model illustrate the implementation method and dress of the utility model by above-described embodiment Structure is set, but the utility model is not limited to the above embodiment, that is, does not mean that the utility model has to rely on above-mentioned side Method and structure could be implemented.Person of ordinary skill in the field is it will be clearly understood that any improvement to the utility model, to this reality With the addition of novel selected implementation method equivalence replacement and step, the selection etc. of concrete mode, the utility model is all fallen within Within protection domain and scope of disclosure.

The utility model is not limited to the above embodiment, it is all using structure similar with the utility model and its method come real All modes of existing the utility model aim, both are within the protection scope of the present invention.
