Abstract

The utility model provides an installation tool of a shaft check ring, and relates to an assembly tool. The installation tool comprises a pressing cylinder and a tapered sleeve, a round straight hole for press fitting is formed in the lower end of the pressing cylinder, the upper end of the tapered sleeve is a tapered end, the maximum diameter of the tapered end is slightly smaller than the inner diameter of the round straight hole of the pressing cylinder, and the lower end of the tapered sleeve is provided with a locating structure matched with a shaft of the shaft check ring to be installed. The angle alpha of the tapered end of the tapered sleeve ranges from 2 degrees to 18 degrees; the locating structure is a locating shaft, and the locating shaft is arranged in a central hole of the shaft of the shaft check ring to be installed during press fitting; alternatively, the locating structure is a locating hole, and the locating hole is formed in the shaft end of the shaft of the shaft check ring to be installed during press fitting. By means of the installation tool, the shaft check ring does not need to be opened, operation force is reduced, labor intensity is lowered, the operation method of the installation tool is simple and convenient to implement, and the installation tool is simple and reliable in structure, low in cost and convenient to popularize and use.

Description

Shaft block ring erecting tools
Technical field
The utility model relates to a kind of assembly tool, particularly a kind of shaft block ring erecting tools.
Background technology
Shaft block ring mainly divides three classes at present: circlip for shaft, axle are with flattening elastic spring, axle-steel silk back-up ring.Wherein circlip for shaft generally uses Circlip tongs to install, and axle is generally installed with sharp screwdriver or nipper plier with flattening elastic spring, axle-steel silk back-up ring.Below this two kinds of existing defects of method and deficiency will be discussed in detail: one, above two kinds of installation methods all need operator to strut back-up ring by larger power, effort; Two, for using and flatten elastic spring, axle-steel silk back-up ring by sharp screwdriver or nipper plier installation shaft, because elastic spring elasticity is less and itself does not have impetus, in installation process, very easily cause back-up ring disconnection or erecting tools to skid, need operator to have higher skill and experience could be competent at the work that elastic spring is installed.
Utility model content
The technical problems to be solved in the utility model is: a kind of shaft block ring erecting tools that skill and experience can more laborsaving installation shaft block ring that do not need is provided.
The technical scheme solving the problems of the technologies described above is: a kind of shaft block ring erecting tools, comprise pressure cylinder, tapered sleeve, described pressure cylinder lower end band is useful on the circular straight hole press-fiting, described tapered sleeve upper end is tapering point, the maximum gauge of tapering point is slightly less than the internal diameter of the circular straight hole of pressure cylinder, and tapered sleeve lower end is with the location structure matching with the axle of shaft block ring to be installed.
Further technical scheme of the present utility model is: the tapering point angle [alpha] of described tapered sleeve is 2~18 °.
Further technical scheme of the present utility model is: described location structure is locating shaft, and while press-fiting, this locating shaft is arranged in the centre bore of axle of shaft block ring to be installed.
Further technical scheme of the present utility model is: described location structure is locating hole, and while press-fiting, this locating hole is arranged on the axle head of axle of shaft block ring to be installed.
Owing to adopting said structure, the shaft block ring erecting tools of the utility model compared with prior art, has following beneficial effect:
1. reduce labour intensity:
Because shaft block ring erecting tools of the present utility model comprises tapered sleeve and pressure cylinder, wherein pressure cylinder lower end band is useful on the circular straight hole press-fiting, and tapered sleeve upper end is tapering point; While press-fiting, tapered sleeve is placed on shaft block ring to be installed axle one end and have good positioning, then shaft block ring is nested with on the tapering point of tapered sleeve, finally depress again pressure cylinder, shaft block ring is slided on the axle of shaft block ring to be installed under the conical surface of tapered sleeve, and be finally stuck in the draw-in groove of this axle.Therefore, the utility model, without strutting shaft block ring, has reduced operation firmly, also greatly reduces labour intensity.
2. method of operating is easy:
What adopt due to shaft block ring erecting tools of the present utility model is tapered sleeve and pressure cylinder form, easy to operate, does not need operator to have higher skill and experience, to almost not requirement of operator.
3. simple and reliable for structure, cost is low,
Because shaft block ring erecting tools of the present utility model only comprises tapered sleeve and pressure cylinder, its structure is very simple, and cost is lower; In addition, the tapering point angle [alpha] of the utility model tapered sleeve is 2~18 °, due to when this tapering, can make the shaft block ring internal diameter gliding along the conical surface of this tapering point slowly increase gradually, the phenomenon of rupture easily having produced while having avoided shaft block ring amplification excessive, therefore, its structure is reliable.
4. be convenient to promote the use of:
Because method of operating of the present utility model is easy, to almost not requirement of operator, and simple and reliable for structure, cost is low, can promote it on a large scale, in each, the shaft block ring enterprise of (comprising that circlip for shaft, axle are with flattening elastic spring, axle-steel silk back-up ring) need to be installed.
Below, the technical characterictic of the shaft block ring erecting tools to the utility model is further described in conjunction with the accompanying drawings and embodiments.
Accompanying drawing explanation
Fig. 1: the structural representation of the shaft block ring erecting tools of the utility model.
Each label in figure is as follows:
1-pressure cylinder, the circular straight hole of 101-, 2-tapered sleeve, 201-tapering point, 202-location structure,
3-shaft block ring, 4-axle.
The specific embodiment
Embodiment mono-:
A kind of shaft block ring erecting tools, comprise pressure cylinder 1, tapered sleeve 2, described pressure cylinder 1 lower end band is useful on the circular straight hole 101 press-fiting, described tapered sleeve 2 upper ends are tapering point 201, these tapering point 201 angle [alpha] are 15 °, the maximum gauge of tapering point 201 is slightly less than the internal diameter of the circular straight hole 101 of pressure cylinder 1, be the maximum gauge of described tapering point 201 than the little 1~3mm of internal diameter of the circular straight hole 101 of pressure cylinder 1, tapered sleeve lower end is with the location structure 202 matching with the axle 4 of shaft block ring 3 to be installed.Described location structure 202 is locating shaft, and while press-fiting, this locating shaft is arranged in the centre bore of axle 4 of shaft block ring 3 to be installed.Described shaft block ring 3 comprises that circlip for shaft, axle are with flattening elastic spring, axle-steel silk back-up ring.
As the one conversion of the present embodiment one, tapering point 201 angle [alpha] of described tapered sleeve 2 also can increase or reduce, and generally get any number in 2~18 °, as 2 °, 5 °, 10 °, 12 °, 13 °, 14 °, 16 °, 17 °, 18 °.
As another conversion of the present embodiment one, described location structure 202 can also be locating hole, and while press-fiting, this locating hole is arranged on the axle head of axle 4 of shaft block ring 3 to be installed.
