Abstract
The utility model provides a flexible three -jaw anchor clamps belongs to mechanical technical field. It is inaccurate that it has solved current three -jaw fixture, presss from both sides the problem of warping with the work piece easily. This flexible three -jaw anchor clamps includes the clamping jaw of setting on the chuck that chuck and three circumference are even, and circular through -hole has been seted up at the chuck middle part, and the clamping jaw includes connecting seat, chuck and two rocker pieces, sets up the slide that can supply the connecting seat radially to slide on the chuck, and through reference column swing joint between the middle part of chuck and the connecting seat, two rocker pieces are the articulating in the both ends of chuck of symmetry respectively, and the inner middle part of chuck is provided with the buffering post. The utility model has the advantages of the clamp force is even, and the location is accurate, and the work piece warp for a short time.
Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of fixture, more particularly to a kind of flexible Three-jaw fixture.
Background technology
Three-jaw fixture is the most general a kind of fixture for machining the various parts of clamping, and the fixture is easy to use, using wide
General, Three-jaw fixture is mainly made up of chuck and clamping jaw, is applied on clamping jaw by mechanical force or hydraulic coupling, produces and clamps and loosen
Action is realized the clamping of workpiece and is unloaded.
Often be may require that in industrial processes at present will need the to be processed of annular workpiece or tubular
Part is fixed, and is fixed by Three-jaw fixture, and each clamping jaw is adjusted by screw rod
The dynamics for clamping is saved, is fixed yet with each clamping jaw, and excircle of workpiece is generally irregular blank or rough turn face, institute
To be difficult to make three clamping degrees of clamping jaw keep unification, this results in workpiece discontinuity in each direction, holds very much
Easily workpiece is set to shift or deform.
The content of the invention
The purpose of this utility model is directed to the above-mentioned problems in the prior art, there is provided a kind of clamping force is uniform,
Accurate positioning, workpiece deforms small flexible Three-jaw fixture.
The purpose of this utility model can be realized by following technical proposal：A kind of flexible Three-jaw fixture, including chuck and
Three circumferentially uniform clamping jaws being arranged on chuck, described chuck middle part offers manhole, it is characterised in that described
Clamping jaw include connecting seat, chuck and two rocker pieces, offered on described chuck and be available for the connecting seat radially slideway that slides,
It is flexibly connected by locating dowel between the middle part of described chuck and connecting seat, what two described rocker pieces were respectively symmetrically is hinged
In the both ends of chuck, the inner middle part of described chuck is provided with bumper post.
In above-mentioned a kind of flexible Three-jaw fixture, the inner face of described bumper post under the state that is compacted is justified with chuck
More than the distance between rocker piece inner face and chuck center of circle, described bumper post is not compacted under state the distance between heart
The distance between inner face and the chuck center of circle are less than the distance between rocker piece inner face and chuck center of circle.This distance and position sets
Put and may be such that workpiece before being clamped, bumper post first touches workpiece, plays cushioning effect, prevents workpiece from deforming.
In above-mentioned a kind of flexible Three-jaw fixture, the inner face of described rocker piece is arc surface, described bumper post
Inner face also be arc surface.
In above-mentioned a kind of flexible Three-jaw fixture, the material of described bumper post is rubber or nylon.Such material can
Prevent workpiece from occurring abrasion in clamping process.
Compared with prior art, this flexible Three-jaw fixture passes through being flexibly connected between chuck and connecting seat, and in chuck
Upper setting bumper post, makes it have uniform force, accurate positioning, the advantages of workpiece deformation is small.

Specific embodiment
The following is specific embodiment of the utility model and with reference to accompanying drawing, further is made to the technical solution of the utility model
Description, but the utility model is not limited to these embodiments.
As shown in figure 1, this flexible Three-jaw fixture includes chuck 1 and three circumferentially uniform clamping jaws being arranged on chuck 1
2, the middle part of chuck 1 offers manhole 3, and clamping jaw 2 includes connecting seat 4, chuck 5 and two rocker pieces 6, offered on chuck 1
The slideway 7 for being available for the radial direction of connecting seat 4 to slide, is flexibly connected between the middle part of chuck 5 and connecting seat 4 by locating dowel 8, and two are floated
What motion block 6 was respectively symmetrically is articulated with the both ends of chuck 5, and bumper post 9 is provided with the middle part of the inner of chuck 5, and bumper post 9 is being pressed
The distance between inner face and the center of circle of chuck 1 under tight state are more than the distance between the inner face of rocker piece 6 and the center of circle of chuck 1,
The distance between the inner face that bumper post 9 is not compacted under state and the center of circle of chuck 1 are justified less than the inner face of rocker piece 6 with chuck 1
The distance between heart, the inner face of rocker piece 6 is arc surface, and the inner face of bumper post 9 is also arc surface, the material of bumper post 9
It is rubber or nylon.
The operation principle of this flexible Three-jaw fixture is as follows：Round piece to be processed is put into fixture, by applying
Hydraulic coupling makes connecting seat 4 drive clamping jaw 2 radially-inwardly to clamp workpiece and fix, due to being activity company between chuck 5 and connecting seat 4
Connect, can make workpiece positioning more precisely and stress in each direction all keeps uniform, and clamp when chuck 5 on
Bumper post 9 can first contact workpiece, play a part of buffering, prevent workpiece occur in clamping process deformation.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement or using similar to described specific embodiment
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although more having used chuck 1, clamping jaw 2, manhole 3, connecting seat 4, chuck 5, rocker piece 6, slideway herein
7th, the term such as locating dowel 8, bumper post 9, but it is not precluded from using the possibility of other terms.It is used for the purpose of using these terms
More easily describe and explain essence of the present utility model；Being construed as any additional limitation is all and this practicality
What new spirit was disagreed.
