Pipe upper end；The center jumper bar is through to flat sleeve bottom from flat sleeve upper end；The elastomeric element is enclosed within flat sleeve pipe
Lower end, positioned at the top of the slab construction of flat sleeve pipe.
Further, the flat sleeve pipe middle part is cased with pad, and elastomeric element is located at the flat board of pad and flat sleeve pipe
Between structure.
Further, the elastomeric element be spring, and spring drift more than external conical sleeve pyramidal structure height.
Further, the pyramidal structure of the external conical sleeve lower end is conical structure.
Further, the center jumper bar bottom is pyramidal structure.
Further, the center jumper bar top is provided with the flat board vertical with center jumper bar.
Beneficial effect of the present invention：
1st, it is close to the edge of axle using the pyramidal structure of external conical sleeve lower end, while under the flat sleeve pipe at external conical sleeve center
The slab construction at end is close to axial end, and flat casing shoe center is axial end center needs perforating position, localization method
It is simple accurate, substantially reduce the workload and error of manual measurement positioning.
2nd, the pyramidal structure of external conical sleeve lower end can be designed according to the cross sectional shape of axle, thus it is different to various cross sections, but
It is the axle of symmetrical structure, all can accurately punches, versatility is high.
3rd, flat sleeve upper end is arranged to hollow tubular structure, center jumper bar therethrough, the perforating to center jumper bar
It is oriented to, while flat casing shoe is provided with slab construction, is close to the end face of axle, it is ensured that is during the jumper bar perforating of center steady
It is qualitative, it is to avoid sidesway occurs during the jumper bar perforating of center, the precision of perforating is improve.
Brief description of the drawings
Accompanying drawing 1 is overall structure sectional view of the present invention；
In accompanying drawing：1 be external conical sleeve, 2 be flat sleeve pipe, 3 centered on jumper bar, 4 be elastomeric element, 5 be pad, 6 be flat board,
7 is axle.
Specific embodiment
In order that those skilled in the art more fully understand technical scheme, with reference to accompanying drawing of the invention,
Clear, complete description is carried out to the technical solution of the utility model, based on the embodiment in the application, ordinary skill
Other similar embodiments that personnel are obtained on the premise of creative work is not made, should all belong to the application protection
Scope.
A kind of axle drilling device, is positioned by external conical sleeve and flat sleeve pipe in the end face of axle, and device is lain in
On the end face of axle, external conical sleeve is pushed, external conical sleeve inwall is fitted with axle edge, it is ensured that the concentricity of centre punch and axial plane,
Finding axial end accurately needs punch position, while elastomeric element is pressurized, forces the slab construction of flat sleeve pipe to be fitted with axial end, protects
The perpendicularity of centre punch and axial end is demonstrate,proved, then has applied impulsive force by center jumper bar, completed the perforating to axle, the device knot
Structure is simple, easy to operate, accurate positioning, high working efficiency.
The invention will be further described with preferred embodiment below in conjunction with the accompanying drawings.
Embodiment one：
As shown in figure 1, a kind of axle drilling device, including upper end in the tapered structure in cylindrical structure lower end external conical sleeve 1,
Bottom is provided with slab construction top in the flat sleeve pipe 2 of cylindrical structure, highly more than the center jumper bar 3, bullet of flat sleeve pipe 2
Property part 4, the cylindrical structure outside diameter of the flat sleeve pipe 2 is slightly less than the interior circular diameter of the upper end cylindrical structure of external conical sleeve 1, outward
The upper end of tapered sleeve 1 is enclosed within the upper end of flat sleeve pipe 2, and can be slided up and down along the cylindrical structure of flat sleeve pipe 2；The center jumper bar 3
The bottom of flat sleeve pipe 2 is through to from the upper end of flat sleeve pipe 2, external tapered sleeve 1 slides up and down on the outside of the cylindrical structure of flat sleeve pipe 2
With guide effect, the up and down motion of the cylindrical structure hollow structure inside of flat sleeve pipe 2 to center jumper bar 3 also has guiding to make
With, and the slab construction of flat sleeve pipe 2 is bonded to each other with all end faces, it is ensured that external conical sleeve 1 and the end face of 3 relative axle of center jumper bar 7
Perpendicularity, it is ensured that on the basis of the accurate positioning of external conical sleeve 1, it is ensured that the perforating of center jumper bar 3 is accurate；4 sets of the elastomeric element
In the lower end of flat sleeve pipe 2, positioned at the top of the slab construction of flat sleeve pipe 2, external conical sleeve 1 is lain on the end face of axle 7, pushed
External conical sleeve 1, makes the inwall of external conical sleeve 1 be fitted with axle edge, while elastomeric element 4 is compressed, further forces the flat of flat sleeve pipe 2
Hardened structure is brought into close contact with the end face of axle 7, it is ensured that during perforating, the stability of whole device.
Embodiment two：
As shown in figure 1, a kind of drilling device according to illustrated by embodiment one, the middle part of flat sleeve pipe 2 is cased with
Pad 5, elastomeric element 4 is located between pad 5 and the slab construction of flat sleeve pipe 2, and the edge of pad 5 is close to external conical sleeve 1 and bores
The top of shape structure, when pushing external conical sleeve 1, external conical sleeve 1 applies pressure by pad 5 to elastomeric element 4, receives elastomeric element 4
Power is uniform, is difficult skew, and elastomeric element 4 is given the slab construction of the bottom of flat sleeve pipe 2 by suffered pressure transmission, makes itself and axle
More closely, additionally, the elastomeric element 4 could be arranged to elastic caoutchouc sleeve, preferred forms are spring to the laminating of 7 end faces,
The stability of spring will get well relative to elastic caoutchouc sleeve, and spring drift more than external conical sleeve 1 pyramidal structure height
Degree, so as to ensure that spring is in compressive state, but bullet all the time when the pyramidal structure of external conical sleeve 1 is in contact with the end surface side of axle 7 edge
The coefficient of elasticity of spring can not be too big, it is to avoid external conical sleeve pushes relatively difficult, or is easily upspring after pushing, and causes device unstable
Fixed, spring is compressed to most short length also can not be too short, it is to avoid external conical sleeve 1 also not with the end contact of axle 7, spring cannot be after
It is continuous to be compressed by.
Embodiment three：
As shown in figure 1, a kind of axle drilling device according to illustrated by embodiment two, the taper of the lower end of the external conical sleeve 1
Depending on shape of cross section of the structure according to axle 7, as long as shape symmetrical centered on the cross section of axle 7, the device all can be set phase
Corresponding pyramidal structure, but because the axle 7 of cylinder is the most commonly used, so corresponding pyramidal structure is generally also configured as conical knot
Structure；The bottom of center jumper bar 3 is pyramidal structure, into sharp tip-shape, is conducive to the end face perforating of axle 7；In punching, need
The bottom of Yao centers jumper bar 3 applies an impulsive force, and the diameter of center jumper bar 3 is too small, and the hammer for applying impulsive force is easily beaten
Partially, cause the discontinuity of center jumper bar 3, the top of center jumper bar 3 is set into the flat board 6 vertical with center jumper bar 3, increase impact
The lifting surface area of power, can make the balance of the perforating of center jumper bar 3 more preferable.
Below the present invention is described in detail, the above, only the preferred embodiments of the invention, when can not
Limit the scope of the present invention, i.e., it is all to make impartial change and modification according to the application scope, all should still belong to covering scope of the present invention
It is interior.
