Technical field
The present invention relates to a kind of assembly tool and installation method thereof, particularly a kind of shaft block ring erecting tools and installation method thereof.
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 is generally used 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.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of shaft block ring erecting tools and installation method thereof 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 invention is: the tapering point angle [alpha] of described tapered sleeve is 2～18 °.
Further technical scheme of the present invention 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 invention 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.
Another technical scheme of the present invention is: a kind of installation method of shaft block ring, and the method comprises the following steps:
A1. prepare: be ready to shaft block ring erecting tools, this erecting tools comprises: comprise pressure cylinder, tapered sleeve;
A2. place tapered sleeve: tapered sleeve is placed on to one end of the axle of shaft block ring to be installed, and the location structure of tapered sleeve is arranged in the centre bore of axle or on axle head;
A3. place shaft block ring: shaft block ring is nested with on the tapering point of tapered sleeve;
A4: press-fit: depress 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.
Further technical scheme of the present invention is: in steps A 4 press-fits, the described pressure cylinder of depressing is by manually directly exerting pressure with hand.
Further technical scheme of the present invention is: in steps A 4 press-fits, the described pressure cylinder of depressing is to exert pressure by the piston rod of hydraulic cylinder.
Owing to adopting said structure, the present invention's shaft block ring erecting tools and installation method thereof compared with prior art, have following beneficial effect:
1. reduce labour intensity:
Because shaft block ring erecting tools of the present invention 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 present invention, 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 invention is tapered sleeve and pressure cylinder form, easy to operate, does not need operator to have higher skill and experience, and operator is not almost required.
3. simple and reliable for structure, cost is low,
Because shaft block ring erecting tools of the present invention only comprises tapered sleeve and pressure cylinder, its structure is very simple, and cost is lower; In addition, the tapering point angle [alpha] of tapered sleeve of the present invention 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 invention is easy, operator is not almost required, and simple and reliable for structure, cost is low, can promote it on a large scale and 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 in each.
