A kind of fast fixture
Technical field:
The utility model relates to a kind of machining clamping device, especially a kind of fast fixture that is used for the knuckle axle journal.
Background technology:
At present, traditional knuckle mechanical processing technique adopts element location such as positioning sleeve and alignment pin more, adopt equipment such as hinge or hook-shaped pressing plate to compress, troublesome poeration has had a strong impact on the working (machining) efficiency of knuckle, waste time and energy, and the processing cost height, unsuitable industrial production in enormous quantities.
The utility model content:
The utility model provides a kind of fast fixture, and it is simple in structure, uses easy to operate, can locate fast and accurately and clamp the knuckle spindle neck, it is processed, time saving and energy saving, working (machining) efficiency is improved greatly, and production cost significantly reduces, and has solved problems of the prior art.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises a round nut, is provided with a tapered sleeve in the front side of round nut, and rear side is provided with a binding nut, and the rear end of tapered sleeve and the front end of binding nut active card respectively are contained in round nut inside; Be connected with one at the internal whorl of binding nut and tighten cover, the front end that tightens cover stretches into tapered sleeve inside, and the tapering that tightens cover front end cylindrical matches with the tapering of tapered sleeve inside taper hole, evenly is provided with the distortion groove of several U-shapeds at the front end edge circumferencial direction that tightens cover; On the tapered sleeve internal side wall, be provided with gathering sill, be fixed on and tighten the guide finger that puts and stretch in the gathering sill.
Be connected with one in the rear end of binding nut outside screw and adjust cover, put in adjustment and be provided with the fixing jackscrew that overlaps with binding nut of adjusting.
The described distortion groove that tightens the cover front end is 4~6.
The gathering sill that is provided with on the described tapered sleeve internal side wall is two, is symmetrical arranged; Symmetry is fixed on and tightens two guide fingers that put and stretch into respectively in the relative gathering sill in position.
The utility model adopts such scheme, simple in structure, easy to use, processing ease tightens cover by rotation adjustment cover through the binding nut drive and moves forward and backward, make tighten the cover front end in tapered sleeve, forms protract unclamp, after contract the clamping mode of operation, operating personnel can be located fast and accurately clamp the knuckle spindle neck, it is processed, time saving and energy saving, improve working (machining) efficiency greatly, significantly reduced production cost simultaneously.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, round nut; 2, tapered sleeve; 3, binding nut; 4, tighten cover; 5, distortion groove; 6, gathering sill; 7, guide finger; 8, adjust cover.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in FIG., the utility model comprises a round nut 1, is provided with a tapered sleeve 2 in the front side of round nut 1, and rear side is provided with a binding nut 3, and the front end of the rear end of tapered sleeve 2 and binding nut 3 active card respectively is contained in round nut 1 inside; Be connected with one at the internal whorl of binding nut 3 and tighten cover 4, the front end that tightens cover 4 stretches into tapered sleeve 2 inside, the tapering that tightens cover 4 front end cylindricals matches with the tapering of tapered sleeve 2 inner taper holes, evenly is provided with the distortion groove 5 of several U-shapeds at the front end edge circumferencial direction that tightens cover 4; On tapered sleeve 2 internal side wall, be provided with gathering sill 6, be fixed on the guide finger 7 that tightens on the cover 4 and stretch in the gathering sill 6.
Be connected with one in the rear end of binding nut 3 outside screw and adjust cover 8, on adjustment cover 8, be provided with the fixing jackscrew of adjusting cover 8 and binding nut 3.The handle that drives binding nut 3 rotations by adjustment cover 8 easy for installation on the cover 8 can adjusted.
The described distortion groove 5 that tightens cover 4 front ends is 4~6.
The gathering sill 6 that is provided with on described tapered sleeve 2 internal side wall is two, is symmetrical arranged; Symmetry is fixed on two guide fingers 7 that tighten on the cover 4 and stretches into respectively in the relative gathering sill in position 6.
During use, by round nut 1 tapered sleeve 2 being fixed on the clamp body, is 1: 8 tapering endoporus in the tapered sleeve 2, with tighten the cover 4 tapering cylindricals match, the effect one of round nut 1 is that tapered sleeve 2 is fixed on the clamp body, the 2nd, guarantee that binding nut 3 and tapered sleeve 2 internal taper holes keep concentric.When clamping the knuckle axle journal it is added man-hour, drive binding nut 3 rotations by adjusting cover 8, because tightening two guide fingers 7 of cover 4 front ends stretches in the gathering sill 6 on tapered sleeve 2 internal side wall, make binding nut 3 drive and tighten when overlapping 4 rotations, tighten the cover 4 can only along gathering sill 6 on the internal taper hole axis of tapered sleeve 2, do before and after straight line move, tighten 4~6 distortion grooves 5 that cover 4 front ends are provided with, make and tighten cover 4 when seesawing, its front end is subjected to the extruding of tapered sleeve 2 internal taper holes, tighten cover 4 endoporus and become big thereupon or diminish, thereby realize clamping or decontroling the effect of knuckle axle journal.
The utility model fast fixture, simple in structure, easy to use, processing ease tightens cover 4 by rotation adjustment cover 8 through binding nut 3 drives and moves forward and backward, make tighten the cover 4 front ends tapered sleeve 2 in, form protract unclamp, after contract the clamping mode of operation, operating personnel can be located fast and accurately clamp the knuckle spindle neck, it is processed, time saving and energy saving, improve working (machining) efficiency greatly, significantly reduced production cost simultaneously.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
