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-pawl positioning clamp.
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-pawl positioning clamp
The purpose of this utility model can be realized by following technical proposal：A kind of floating Three-pawl positioning clamp, including card
Disk and three circumferentially uniform clamping jaws being arranged on chuck, described chuck middle part offer manhole, it is characterised in that
Described clamping jaw includes connecting seat, chuck and two rocker pieces, is offered on described chuck and is available for what connecting seat was radially slided
Slideway, is flexibly connected between the middle part of described chuck and connecting seat by locating dowel, and two described rocker pieces are respectively symmetrically
The both ends for being articulated with chuck, the medial extremity middle part of described rocker piece is provided with bumper post, the two ends of described rocker piece
Inside portion has raised gripping block, and the block being connected with chuck is provided between described every adjacent chuck.
In a kind of above-mentioned floating Three-pawl positioning clamp, the medial surface of described rocker piece upper clamping block is to cave inward
Arc surface, the inner face of described bumper post is also the arc surface for caving inward.
In a kind of above-mentioned floating Three-pawl positioning clamp, the inner face of described bumper post under the state that is compacted and card
More than the distance between gripping block inner face and chuck center of circle, described bumper post is not compacted state in the distance between disk center of circle
Under the distance between inner face and the chuck center of circle less than the distance between gripping block inner face and chuck center of circle.This distance and position
Setting may be such that workpiece be clamped before, bumper post first touches workpiece, plays cushioning effect, prevents workpiece from deforming.
In a kind of above-mentioned floating Three-pawl positioning clamp, the material of described bumper post is rubber or nylon.Such material
Material can prevent workpiece from occurring abrasion in clamping process.
Compared with prior art, being flexibly connected between this floating Three-pawl positioning clamp chuck and connecting seat, and be arranged on
Bumper post is set on rocker piece on chuck, uniform force, accurate positioning is 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-pawl positioning clamp includes chuck 1 and three circumferentially uniform are arranged on chuck 1
Clamping jaw 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, opened on chuck 1
The slideway 7 for being available for the radial direction of connecting seat 4 to slide is provided with, is flexibly connected by locating dowel 8 between the middle part of chuck 5 and connecting seat 4, two
What individual rocker piece 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, floats
The two ends inside portion of block 6 has raised gripping block 10, and the block 11 being connected with chuck 1 is provided between every adjacent chuck 5,
The material of bumper post 9 is rubber or nylon, and the medial surface of the upper clamping block 10 of rocker piece 6 is the arc surface for caving inward, bumper post 9
Inner face be also the arc surface that caves inward.
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 rocker piece 6
On bumper post 9 can first contact workpiece, play a part of buffering, prevent workpiece from occurring deformation in clamping process, chuck 5 is floating
The block 11 being connected in when dynamic on chuck 1 can limit the pendulum angle of chuck 5.
In order to this floating Three-pawl positioning clamp is before workpiece is clamped, bumper post 9 first touches workpiece, and its bumper post 9 is in quilt
The distance between inner face and the center of circle of chuck 1 under impaction state more than between the inner face of gripping block 10 and the center of circle of chuck 1 away from
From bumper post 9 is not compacted the distance between inner face and center of circle of chuck 1 under state less than the inner face of gripping block 10 and chuck
The distance between 1 center of circle.
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, block 11, but it is not precluded from using the possibility of other terms.Using this
A little terms are used for the purpose of more easily describing and explaining essence of the present utility model；It is construed as what any one was added
Limitation is all disagreed with the utility model spirit.
