2, the pyramidal structure of external conical sleeve lower end can be designed according to the cross sectional shape of axle, thus different to various cross section, but be the axle of symmetrical structure, all can accurately punch, versatility is high.
3, flat sleeve upper end is arranged to the tubular structure of hollow, center jumper bar runs through wherein, the perforating of center jumper bar is led, flat casing shoe is provided with slab construction simultaneously, be close to the end face of axle, ensure that the stability during jumper bar perforating of center, avoid, during the jumper bar perforating of center, sidesway occurs, improve the precision of perforating.
Accompanying drawing explanation
Accompanying drawing 1 is overall structure sectional view of the present invention.
In accompanying drawing: 1 be external conical sleeve, 2 for jumper bar, 4 centered by flat sleeve pipe, 3 be elastomeric element, 5 be pad, 6 for dull and stereotyped, 7 be axle
Detailed description of the invention
Technical scheme of the present invention is understood better in order to make those skilled in the art; below in conjunction with accompanying drawing of the present invention; clear, complete description is carried out to technical scheme of the present invention; based on the embodiment in the application; other roughly the same embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all should belong to the scope of the application's protection.
A kind of axle drilling device, positioned at the end face of axle by external conical sleeve and flat sleeve pipe, device is lain on the end face of axle, press down external conical sleeve, fitted in external conical sleeve inwall and axle edge, ensure that the concentricity of centre punch and axial plane, find axial end accurately and need punch position, elastomeric element pressurized simultaneously, the slab construction of flat sleeve pipe and axial end is forced to be fitted, ensure that the perpendicularity of centre punch and axial end, again by applying impulsive force to center jumper bar, complete the perforating to axle, this apparatus structure is simple, easy to operate, accurate positioning, operating efficiency is high.
Below in conjunction with accompanying drawing and preferred embodiment, the invention will be further described.
Embodiment one:
As shown in Figure 1, a kind of axle drilling device, comprise external conical sleeve 1 that upper end is the tapered structure in cylindrical structure lower end, bottom be provided with slab construction top be cylindrical structure flat sleeve pipe 2, the center jumper bar 3 being highly greater than flat sleeve pipe 2, elastomeric element 4, the cylindrical structure outside diameter of described flat sleeve pipe 2 is slightly less than the interior circular diameter of external conical sleeve 2 upper end cylindrical structure, external conical sleeve 1 upper end is enclosed within flat sleeve pipe 2 upper end, and can slide up and down along the cylindrical structure of flat sleeve pipe 2; Described center jumper bar 3 is through to bottom flat sleeve pipe 2 from flat sleeve pipe 2 upper end, outside the cylindrical structure of flat sleeve pipe 2, external sliding up and down of tapered sleeve 1 has guide effect, the cylindrical structure hollow structure inside of flat sleeve pipe 2 also has guide effect to moving up and down of center jumper bar 3, and the slab construction of flat sleeve pipe 2 and all end faces bonded to each other, ensure that the perpendicularity of external conical sleeve 1 axle 7 relative to center jumper bar 3 end face, ensure on the basis of the accurate positioning of external cover 1, guarantee that center jumper bar 3 perforating is accurate; Described elastomeric element 4 is enclosed within flat sleeve pipe 2 lower end, be 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, press down external conical sleeve 1, fitted in external conical sleeve 1 inwall and axle edge, elastomeric element 4 is compressed simultaneously, forces the slab construction of flat sleeve pipe 2 and axle 7 end face to fit tightly further, ensure that in perforating process, the stability of whole device.
Embodiment two:
As shown in Figure 1, a kind of drilling device illustrated by embodiment one, described flat sleeve pipe 2 middle part cover has pad 5, elastomeric element 4 is between pad 5 and the slab construction of flat sleeve pipe 2, the edge of pad 5 is close to the top of external conical sleeve 1 pyramidal structure, when pressing down external conical sleeve 1, external conical sleeve 1 applies pressure by pad 5 to elastomeric element 4, make elastomeric element 4 uniform force, not easily offset, and suffered pressure is passed to the slab construction of flat sleeve pipe 2 bottom by elastomeric element 4, itself and axle 7 end face is made to fit tightr, in addition, described elastomeric element 4 can be set to elastic caoutchouc sleeve, preferred forms is spring, the stability of spring will be got well relative to elastic caoutchouc sleeve, and the drift of spring is greater than the height of the pyramidal structure of external conical sleeve 1, thus ensure when the pyramidal structure of external conical sleeve 1 contacts with axle 7 end surface side edge, spring is in compressive state all the time, but the coefficient of elasticity of spring can not be too large, external conical sleeve is avoided to press down more difficult, or press down and easily to be upspring afterwards, cause device unstable, spring is compressed to the shortest length also can not be too short, avoid external conical sleeve 1 also not with axle 7 end contact, spring just can not continue be have compressed.
Embodiment three:
As shown in Figure 1, a kind of axle drilling device illustrated by embodiment two, the pyramidal structure of described external conical sleeve 1 lower end is determined according to the shape of cross section of axle 7, as long as shape symmetrical centered by the cross section of axle 7, this device all can arrange corresponding pyramidal structure, but because columniform axle 7 is the most conventional, so corresponding pyramidal structure is also set to conical structure usually; Jumper bar 3 bottom, described center is pyramidal structure, becomes sharp tip-shape, is conducive to the perforating of axle 7 end face; When punching, need to apply an impulsive force in center jumper bar 3 bottom, and the diameter of center jumper bar 3 is too small, the hammer applying impulsive force easily trains off, cause center jumper bar 3 discontinuity, center jumper bar 3 top is arranged the flat board 6 vertical with center jumper bar 3, increases the lifting surface area of impulsive force, the balance of center jumper bar 3 perforating can be made better.
Below the present invention be described in detail, the above, be only the preferred embodiment of the present invention, when not limiting the scope of the present invention, namely allly does impartial change according to the application's scope and modify, all should still belong in covering scope of the present invention.
