The coaxial locating mould of the multiple holes of the machine component is applicable to coaxial assembly and welding of the multiple holes of the machine component, can guarantee concentricity and location accuracy of the multiple holes of the machine component, and has the advantages of being simple in structure, convenient to operate, easy to assemble and disassemble, non-deformable, long in service life, high in production efficiency and low in cost, causing no damage on welding parts, having no environmental requirement and the like.
Description
Technical field
The utility model relates to the positioning clamping fixture of assembling and welding use, is a kind of mechanical component porous coaxial positioning mold.
Background technology
In a lot of occasions, to mechanical component with holes, no matter be assembling, or welding has axiality requirement, generally every have axiality to require to assembly parts, capital adopts an axis in tandem in mechanical component porous, locate the axiality problem solving in coaxial assembling and welding process, so in practical operation locating shaft and hole be subtract poor cooperation will be gapped, because the gapped displacement that mechanical component will produce different directions in assembling and welding process, locating shaft is clamped and made dismounting difficulty, when dismounting, need to firmly impact or push up pressure could release axis, in operating process, can produce certain noise, labour intensity is large, inefficiency, coaxial precision also cannot guarantee.
Summary of the invention
Technical problem to be solved of the present utility model is, a kind of axiality and positioning precision that can guarantee mechanical component porous is provided, simple to operate, easily fills, tears open, indeformable mechanical component porous coaxial positioning mold.
The technical scheme that solves its problem employing is, a kind of mechanical component porous coaxial positioning mold, its special character is: it comprises the locating shaft that is vertically two halves, on the locating shaft of described two halves, be provided with the angle of wedge, on the locating shaft of described two halves, be nested with at least two swelling devices, the sympodium pull bar that the locating shaft of described two halves arranges by its axle head, connecting pin is connected with sympodium positioning clamp nut, the structure of described swelling device is, comprise the positioning framework on the locating shaft that is placed on two halves, be contained in positioning framework and contact the tapered bar coordinating with the locating shaft angle of wedge of two halves, be threaded with positioning framework and push up the jackscrew of pressing tapered bar.
The angle that the angle of wedge is set on the locating shaft of described two halves is 12 ° ~ 18 °.
Mechanical component porous coaxial positioning mold of the present utility model is applicable to coaxial assembling and the welding of mechanical component porous, can guarantee axiality and the positioning precision of mechanical component porous, have simple in structurely, simple to operate, easily fill, tear open, indeformable, do not damage weldment, long service life, does not have environmental requirement, production efficiency is high, low cost and other advantages.
Accompanying drawing explanation
Fig. 1 is that mechanical component porous coaxial positioning positioner structure master looks schematic diagram;
Fig. 2 is A-A cross-sectional schematic in Fig. 1;
Fig. 3 is the local enlarged diagram of C in Fig. 1.
In figure: 1 resilient sleeve, the locating shaft of 2 two halves, 3 connecting pins, 4 sympodium pull bars, 5 sympodium positioning clamp nuts, 6 tapered bars, 7 postings, 8 jackscrews, 9 angles of wedge, 10 frames, 11 mechanical components.
The specific embodiment
The utility model is described in further detail to utilize the drawings and specific embodiments below.
With reference to Fig. 1-3, mechanical component porous coaxial positioning mold of the present utility model, comprise the locating shaft 2 that is vertically two halves, on the locating shaft 2 of described two halves, be provided with the angle of wedge 9, on the locating shaft 2 of described two halves, be nested with at least two swelling devices, the sympodium pull bar 4 that the locating shaft 2 of described two halves arranges by its axle head, connecting pin 3 and sympodium positioning clamp nut 5 are connected.The structure of described swelling device is, comprises the positioning framework 7 on the locating shaft 2 that is placed on two halves, is contained in positioning framework 7 and contact the tapered bar 6 coordinating with the locating shaft angle of wedge 9 of two halves, is threaded and pushes up the jackscrew 8 of pressure tapered bar 6 with positioning framework 7.
The angle that the angle of wedge 9 is set on the locating shaft 2 of described two halves is 12 ° ~ 18 °.In addition, different according to the aperture of required coaxial positioning, be also provided with several resilient sleeve 1 that internal diameter is identical, external diameter is different, resilient sleeve 1 is axially cutting open a seam.The diameter of the locating shaft 2 of two halves should conform to mechanical component Kongzui minor diameter, Quenching Treatment hardness HRC38-41, and linearity should be less than axiality.
Use mechanical component porous coaxial positioning mold, while being used for regulating a plurality of mechanical components 11 with frame 10 welding during axiality: two ends sympodium positioning clamp nut 5 is tightened and made the locating shaft 2 of two halves merge one diameters to diminish immediately, through each mechanical component 11, need coaxial hole, in operating process, the symmetrical place in two ends and interval at the locating shaft 2 of two halves loads onto swelling device, adjust behind position at the uniform jackscrew 8 that screws each swelling device, in the angle of wedge 9 of the locating shaft 2 of the moving tapered bar 6 jacking two halves of jackscrew 8 pushing, the locating shaft 2 of two halves is opened, while eliminates in the gap of the strength control Xia Jiangge hole contact-making surface of the locating shaft 2 of two halves, reach coaxial object.Use the different resilient sleeve 1 of external diameter by the size adjustment in mechanical component 11 apertures unanimously, uniform the tightening afterwards of each jackscrew 8 just can be carried out single stepping at any time.In the time of need to dismantling, each jackscrew 8 is unclamped and drive tapered bar 6 to fall back on initial position ，Jiang two ends sympodium positioning clamp nut 5 to tighten the locating shaft 2 of two halves is integrally combined again, in one end arbitrarily, extract out.
The utility model is not limited to this specific embodiment, the enlightenment that those skilled in the art obtain according to the utility model, need not just can, by changing size, the length of locating shaft diameter, assembling mode and the posting portion of one fill mode, just can realize effect of the present utility model through creative work.
