Abstract

The utility model relates to an assembly fixture which comprises a fixture body, a slider and a cylinder. The slider can slide vertically in the fixture body, the lower end of the slider can extend out of the fixture body, the cylinder is arranged on the lower surface of the slider, the diameter of the cylinder is smaller than that of the lower surface of the slider, the fixture body is hollow, a circular hole communicated with the inside of the fixture body is arranged at the lower end of the fixture body, slide grooves are symmetrically arranged on the inner surface of the fixture body, the slider is 'T'-shaped, a 'longitudinal' portion of the 'T'-shaped slider is positioned in the circular hole, two ends of a 'transverse' portion of the 'T'-shaped slider are positioned in the slide grooves, and a compression spring is arranged between the top of the slider and the inner top of the fixture body. The assembly fixture is simple and convenient to operate and high in assembly efficiency, the labor cost is equivalently reduced, a bearing assembled by the aid of the assembly fixture is good in sealing effect, and the assembly quality is improved.

Description

A kind of assembling jig

Technical field

The utility model relates to a kind of assembling jig, particularly a kind of assembling jig for running in bearings and seal cover.

Background technology

Bearing is to work the parts of fixing and reducing the load coefficient of friction in mechanical transmission course, and bearing can be applied in the different fields.For the bearing of low noise, high-seal, its serviceability requires to forbid leakage of oil and gas leakage, this be need to be between the inner ring of bearing and outer ring the fitting tight lid.It is at present general that what adopt is the assembling that the mode of manually beaing seal cover realizes seal cover and bearing, such assembling mode, efficiency of assembling is low, break-in has increased cost of labor, and because artificial operation is skimble-scamble, the sealing effectiveness of the bearing that therefore assembles alternates betwwen good and bad, and has affected assembly quality, can not satisfy client's requirement.

The utility model content

The utility model purpose is that the assembling jig that a kind of efficiency of assembling is high, assembly quality is high is provided in order to overcome the deficiencies in the prior art.

For achieving the above object, the technical solution adopted in the utility model is: a kind of assembling jig comprises clamp body, gliding mass and cylinder; Described gliding mass can slide up and down in clamp body and clamp body can be stretched out in the lower end; The lower surface of described gliding mass is provided with cylinder; The diameter of described cylinder is less than gliding mass lower surface diameter.

Preferably, described clamp body is hollow form; Described clamp body lower end has the circular hole that communicates with clamp body inside; The inner surface of described clamp body is arranged with chute; Described gliding mass is " T " font; "T"-shaped " l " section of described gliding mass is in the circular hole; The two ends of "-" section of described gliding mass " T " are in the chute.

Preferably, be provided with Compress Spring between the top of described gliding mass and the clamp body inner tip.

Because the utilization of technique scheme, the utility model compared with prior art has following advantages:

Assembling jig of the present utility model, in the process of using, seal cover can be enclosed within the bottom of gliding mass, the inner ring of bearing entangles the cylinder of gliding mass lower surface, and directly the fixture under pressure body just can have been realized the assembling between seal cover and bearing, and is easy to operate, efficiency of assembling is high, break-in has reduced cost of labor, and the good sealing effect of the bearing that assembles out, has increased assembly quality; And owing to be provided with Compress Spring between the top of gliding mass and the clamp body inner tip, can in the process of fitting tight lid, play a kind of effect of buffering, bearing is contacted with the rigidity of clamp body, become the buffering contact, avoid the damage of clamp body to bearing.

Description of drawings

Below in conjunction with accompanying drawing technical solutions of the utility model are described further:

Accompanying drawing 1 is the structural representation of assembling jig of the present utility model;

Structural representation when accompanying drawing 2 is assembling jig assembling original state of the present utility model;

Structural representation when accompanying drawing 3 is assembling jig assembling completion status of the present utility model;

Wherein: 1, clamp body; 2, gliding mass; 3, cylinder; 4, circular hole; 5, chute; 6, Compress Spring; 7, bearing; 8, seal cover.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Described in the utility model a kind of assembling jig as shown in Figure 1 comprises clamp body 1, gliding mass 2 and cylinder 3; The lower surface of described gliding mass 2 is provided with cylinder 3; The diameter of described cylinder 3 is less than gliding mass 2 lower surface diameters; Described clamp body 1 is hollow form; Described clamp body 1 lower end has the circular hole 4 that communicates with clamp body 1 inside; The inner surface of described clamp body 1 is arranged with chute 5; Described gliding mass 2 is " T " font; Described gliding mass 2 "T"-shaped " l " sections are in the circular hole 5; The two ends of "-" section of described gliding mass 2 " T " are in the chute 5; Described gliding mass 2 can slide up and down in clamp body 1 and clamp body 1 can be stretched out in the lower end; Be provided with Compress Spring 6 between the top of described gliding mass 2 and clamp body 1 inner tip.

Described in the utility model a kind of assembling jig shown in accompanying drawing 2,3, the diameter of described cylinder 3 equals the diameter of bearing 7 inner rings; The diameter of described gliding mass 2 ends equals the diameter of seal cover 8; In use, seal cover 8 can be enclosed within the bottom of gliding mass 2, the inner ring of bearing 7 entangles the cylinder 3 of gliding mass 2 lower surfaces, directly the fixture under pressure body just can have been realized the assembling of 7 on seal cover 8 and bearing, easy to operate, efficiency of assembling is high, and break-in has reduced cost of labor, and the good sealing effect of the bearing that assembles out has increased assembly quality; And owing to be provided with Compress Spring 8 between the top of gliding mass 2 and clamp body 1 inner tip, can in covering 8 process, fitting tight play a kind of effect of buffering, bearing 7 is contacted with the impact of clamp body 1, become the buffering contact, avoided the damage of 1 pair of bearing 7 of clamp body.

Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
