Abstract
The utility model discloses a kind of elastic collar expanding device, comprise pushing sleeve and tapered plug, pushing sleeve is cylindrical and its bottom has counterbore for holding tapered plug, and counterbore top middle portion has through hole, and tapered plug is held greatly and is installed on down in counterbore.This device is by the relative motion of pushing sleeve and tapered plug, make elastic collar tapered beyond the Great Wall from small end to the mobile expanding realizing elastic collar of large end, to reach the object in the collar groove that arbitrary dimension, arbitrary shape, elastic collar that hardness level is different to be loaded on axle, compared to traditional expanding manually, the utility model has that structure is simple, easy and simple to handle, expanding efficiency is high, precision is high and the advantage such as applied widely.
Description
Technical field
The utility model relates to the assembly tool of a kind of axle with outer elastic collar, is specifically related to a kind of elastic collar expanding device.
Background technology
In the assembling process of axle with outer elastic collar, often all need first will again collar to be enclosed within groove that axle is offered after the opening swell of elastic collar, in prior art, the general elastic collar expanding device used is generally that traditional clamp are by collar opening swell, but the scope of application of this clamp is limited, when the diameter of elastic collar is excessive or too small, time in the too high situation of hardness, traditional clamp are also inapplicable, this is because the opening dimension of traditional clamp is limited, its opening part then cannot be made to open completely for the elastic collar that diameter is excessive, cause assembling difficulty, and can cause because clamp own dimensions is excessive for the elastic collar that diameter is too small cannot the problem of expanding, and the elastic collar of high rigidity can cause expanding difficulty because its rigidity is too high, cannot ensure that elastic collar maintains expanding state, and then cause assembling, in addition, carry out expanding mainly rely on the experience of operating personnel to operate with traditional clamp to elastic collar, error is comparatively large, and cannot ensure the accuracy after assembling, also need manpower and the time of at substantial, efficiency is very low, meanwhile, can spend due to elastic-restoring force when manual expanding for the too high collar of consistency and elasticity and cause greatly collar easily to come off the situation of resilience, there is larger potential safety hazard.
Utility model content
The utility model aims to provide a kind of elastic collar expanding device, the problem that error is large, precision is low, human time consumes greatly, potential safety hazard is large existing when adopting clamp to carry out expanding to elastic collar to solve in prior art.
The utility model is achieved by following technical solution:
A kind of elastic collar expanding device, comprises pushing sleeve and tapered plug, and described pushing sleeve is cylindrical and its bottom has counterbore for holding tapered plug, and counterbore top middle portion has through hole, and described tapered plug is held greatly and is installed on down in counterbore.
Described tapered plug top middle portion is connected with columniform boss, and this boss is through described through hole.
The external diameter of described tapered plug outside diameter >=need the be socketed axle of elastic collar.
Described tapered plug end diameter < is by the internal diameter of expanding elastic collar.
The beneficial effects of the utility model are:
Compared with prior art, the elastic collar expanding device that the utility model provides, by the relative motion of pushing sleeve and tapered plug, make elastic collar tapered beyond the Great Wall from small end to the mobile expanding realizing elastic collar of large end, to reach object arbitrary dimension, arbitrary shape, elastic collar that hardness level is different be loaded in the collar groove of shaft forgings, compared to traditional expanding manually, the utility model has that structure is simple, easy and simple to handle, expanding efficiency is high, precision is high and the advantage such as applied widely.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model;
Fig. 2 is the top view of pushing sleeve in the utility model;
Fig. 3 is the A-A sectional view of Fig. 2;
In figure: 1-pushing sleeve, the tapered plug of 2-, 3-boss, 4-through hole, 5-counterbore.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but described in required protection domain is not limited to;
As Figure 1-3, the elastic collar expanding device that the utility model provides, it comprises pushing sleeve 1 and tapered plug 2, and described pushing sleeve 1 is cylindrical and its bottom has counterbore 5 for holding tapered plug 2, counterbore 5 top middle portion has through hole 4, and the large end of described tapered plug 2 is installed in counterbore 5 down.To the elastic collar of expanding be needed to be enclosed within tapered plug 2 from small end, then pushing sleeve 1 is enclosed within tapered plug 2 outside, promote pushing sleeve 1 and can drive elastic collar on tapered plug 2 from small end to holding movement greatly, realize the expanding of elastic collar.
For the ease of being exited from pushing sleeve 1 by tapered plug 2, tapered plug 2 top middle portion is connected with columniform boss 3, and this boss 3, through described through hole 4, promotes boss 3 and tapered plug 2 can be realized to exit from pushing sleeve 1.
In order to ensure that the elastic collar after expanding can be enclosed within axle, the external diameter of described tapered plug 2 outside diameter >=need the be socketed axle of elastic collar.
In order to realize elastic collar to be enclosed within tapered plug 2, tapered plug 2 end diameter < is by the internal diameter of expanding elastic collar.
During use, the elastic collar that need assemble is enclosed within tapered plug 2 from the little conical surface end of tapered plug 2, the large end of tapered plug 2 is fixed on the shaft end that need be socketed elastic collar, then pushing sleeve 1 is enclosed within tapered plug 2 outside, then on pushing sleeve 1, axial force is applied, elastic collar is from the small end of tapered plug 2 to holding movement greatly under the effect of pushing sleeve 1, and namely moving process realizes the expanding of elastic collar, and last elastic collar departs from from tapered plug 2 and is enclosed within axle.
