Abstract
The utility model relates to a no axial displacement bipyramid elastic fixture, including the external diameter from a left side to part anchor clamps body, abutment sleeve that four ladders reduce in proper order on the right side, prop set, cone, end cover and pull rod, the utility model discloses a removal of lathe piston drives the axial displacement of pull rod, and the axial displacement of pull rod drives the axial displacement of cone, and the axial displacement of cone turns into the radial movement who props the cover, realize the clamp of cylinder jacket tight with unclamp, the size of anchor clamps is according to the hole of cylinder liner and confirm. These anchor clamps extensive application at present is to the semifinishing of cylinder jacket to great improvement semifinishing's precision.
Description
Technical field
This utility model relates to a kind of fixture, is specifically related to a kind of without moving axially bipyramid spring chuck.
Background technology
The frock that cylinder jacket semifinishing at present is used is single cone inner support clamp or shaftless to displacement self-centering fixture.The feature of single cone inner support clamp is that fixture can produce with pull bar and moves axially, workpiece also creates with fixture and moves axially simultaneously, now cylinder jacket adds and cannot accomplish man-hour to be accurately positioned, operative employee can only be leaned on to observe with eye, therefore end face allowance must be the biggest, otherwise there will be the situation that end face processing is non-round, use this fixture the highest to the skill set requirements of operative employee.It is that fixture is without realizing clamping in the case of moving axially without moving axially the feature of self-centering fixture, this fixture is capable of being accurately positioned of workpiece, reduce allowance and to operative employee according to lazyness, but this fixture is point and absorption surface, easily cause the deformation of workpiece, design this fixture in order to solve problem above.
Utility model content
In order to overcome the defect of prior art, this utility model provides a kind of without moving axially bipyramid spring chuck.
Based on above-mentioned purpose, this utility model adopts the following technical scheme that:
A kind of without moving axially bipyramid spring chuck, chuck body, abutment sleeve, support set, cone, end cap and pull bar that four ladders are sequentially reduced is divided from left to right including external diameter；Chuck body axially inside direction is provided with the movable chamber movable for pull bar, the outer wall of chuck body is designated as the first end difference, the second end difference, the 3rd end difference and fourth order ladder portion the most successively, it is arranged with abutment sleeve on 3rd end difference of chuck body, the fourth order ladder portion of chuck body is arranged with cone and support set the most successively；On the periphery of support set, the most uniform some spring grooves, are provided with spring in spring groove, the right-hand member of abutment sleeve and support set apical grafting, between abutment sleeve and chuck body, are all connected by securing member between abutment sleeve and support set；End cap is fixed on the right side of cone by securing member, and the middle part of end cap is provided with through hole；Pull bar sequentially passes through end cap and chuck body from right to left, and the left end of pull bar stretches out outside chuck body.
This utility model is moved axially by the mobile drive pull bar of lathe piston, pull bar move axially moving axially of band movable cone, moving axially of cone is converted into moving radially of support set, it is achieved the clamping of cylinder jacket with unclamp, the size of fixture determines according to the endoporus of cylinder sleeve.This fixture has been widely applied in the semifinishing of cylinder jacket at present, and is greatly improved semi-finished precision.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of without moving axially bipyramid spring chuck, chuck body 1, abutment sleeve 7, support set 2, cone 3, end cap 5 and pull bar 6 that four ladders are sequentially reduced is divided from left to right including external diameter；Chuck body 1 axially inside direction is provided with the movable chamber movable for pull bar, the outer wall of chuck body 1 is designated as the first end difference, the second end difference, the 3rd end difference and fourth order ladder portion the most successively, it is arranged with abutment sleeve 7 on 3rd end difference of chuck body 1, the fourth order ladder portion of chuck body 1 is arranged with cone 3 and support set 2 the most successively；The most uniform some spring grooves on the periphery of support set 2, are provided with spring 4, the right-hand member of abutment sleeve 7 and support set 2 apical grafting, between abutment sleeve 7 and chuck body 1, are all connected by securing member between abutment sleeve 7 and support set 2 in spring groove；End cap 5 is fixed on the right side of cone 3 by securing member, and the middle part of end cap 5 is provided with through hole；Pull bar 6 sequentially passes through end cap 5 and chuck body 1 from right to left, and the left end of pull bar 6 stretches out outside chuck body 1.
During use, pull bar 6 in this fixture is linked on the main shaft piston of lathe by a big pull bar, chuck body 1 is connected with lathe ring flange by seam and six screws, abutment sleeve 7 is fixed in chuck body 1 by the screw of four M3, support set 2 is fixed on abutment sleeve 7 by four M3 screws, and three springs are assembled in the spring groove of support set 2, and cone 3 is assembled in support set 2, and it is fixed together with chuck body 1 by the screw of a M10, prevents radial rotating.End cap 5 is fixed in cone 3 by the screw of four M5, and pull bar 6 is linked together by nut with end cap 5.
When lathe piston is moved to the left, driving big pull bar to be moved to the left, now the pull bar 6 in chuck body 1 is moved to the left with big pull bar, and cone 3 is moved to the left under the drive of end cap 5 simultaneously, support set 2 starts outside spreading due to the extruding of cone 3, it is achieved the purpose of clamping workpiece.
When needing to unclamp after cylinder jacket is processed, lathe piston moves right, and big pull bar and pull bar 6 move right with piston, support set 2 under the elastic force effect of spring 4 to retraction, cone 3 by support set 2 be pressed against move right, the final purpose realizing unclamping workpiece.
