It is inaccurate that it has solved current three -jaw fixture, the easy problem that the deformation appears when pressing from both sides tight work piece. This three -jaw anchor clamps float includes the clamping jaw of setting on the chuck that chuck and three circumference are even, circular through -hole has been seted up at the chuck middle part, the clamping jaw includes the connecting seat, chuck and two rocker pieces, set up the slide that can supply the connecting seat radially to slide on the chuck, 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, the medial extremity middle part of rocker piece is provided with the buffering post, the both ends inside portion of rocker piece has the tight piece of bellied clamp. 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 floating 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 floating Three-jaw fixture
The purpose of this utility model can be realized by following technical proposal：A kind of floating 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 medial extremity middle part of described rocker piece is provided with bumper post, the two ends inside portion of described rocker piece
With raised gripping block.
In a kind of above-mentioned floating Three-jaw fixture, the medial surface of described rocker piece upper clamping block is the circle for caving inward
Cambered surface, the inner face of described bumper post is also the arc surface for caving inward.
In a kind of above-mentioned floating 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 gripping block 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 gripping block 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 a kind of above-mentioned floating 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, being flexibly connected between this floating Three-jaw fixture chuck and connecting seat, and installed in chuck
On rocker piece on bumper post is set, uniform force, accurate positioning are made it have, 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 floating 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 the medial extremity middle part of rocker piece 6 is provided with bumper post 9, rocker piece 6
Two ends inside portion has a raised gripping block 10, and the material of bumper post 9 is rubber or nylon, the upper clamping block 10 of rocker piece 6 it is interior
Side is the arc surface for caving inward, and the inner face of bumper post 9 is also the arc surface for caving inward.
In order to this floating Three-jaw fixture is before workpiece is clamped, bumper post 9 first touches workpiece, and its bumper post 9 is being compacted
The distance between inner face and the center of circle of chuck 1 under state delay more than the distance between the inner face of gripping block 10 and the center of circle of chuck 1
The distance between inner face that post 9 is not compacted under state and the center of circle of chuck 1 are rushed less than the inner face of gripping block 10 and the center of circle of chuck 1
The distance between.
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, gripping block 10, but it is not precluded from using the possibility of other terms.Use these terms
Just for the sake of more easily describing and explaining essence of the present utility model；It is construed as any additional limitation all
Disagreed with the utility model spirit.
