Workpiece.With three anti-pawls are changed on three claws, for installing the workpiece being relatively large in diameter.Easily worn and torn with scroll chuck and led
The precision reduction of processing workpiece is caused, and axiality is poor, clamping thin-walled parts are yielding, in addition in turning easily due to Cutting Force
Degree causes workpiece to depart from greatly.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of fixture, and the fixture clamping precision is high, and axiality is high,
Processing thin-walled parts are unlikely to deform and clamping great efforts.
Technical solution of the present utility model is to provide a kind of fixture with following structure, including flange and connection
In the circular pedestal in flange one end, pedestal is made up of elastomeric material, and described pedestal middle part is provided with the shape of deformation in the axial direction
Change portion, described deformations side is provided with least two circumferentially spaced corpus unguis, and described deformations axial direction is received
Make corpus unguis enlarged-diameter or diminution to active force deformation.
Preferably, described pedestal includes the fixed part being connected with flange, and described deformations are arranged in fixed part.
Preferably, described deformations include being arranged on the step-like annulus that outer is connected with fixed part.
Preferably, also including with pedestal away from corpus unguis side be connected to drive the drive rod of pedestal deformation.
Preferably, described pedestal is removably connected with connecting rod, is provided with what is slided for drive rod in described connecting rod
Chute.
Preferably, described deformations are provided with the projection corresponding with corpus unguis, and described projection is detachably connected with corpus unguis.
Preferably, described corpus unguis is both connected on an annular ring.
Preferably, described corpus unguis cross section is sector.
Preferably, described pedestal by elastic steel into.
After using above structure, fixture of the present utility model, compared with prior art, with advantages below:By flange
Fixed round base, pedestal deformations deformation in the axial direction described under external force, due to for round base and along axle
Line is acted on, and makes deformations deformation uniform, even if corpus unguis high precision, axiality in clamping is high, and processing thin-walled parts are difficult
Deformation, forms larger dynamics, it is ensured that the stability of clamping additionally by pedestal deformation energy in less stroke.

Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Refer to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, fixture of the present utility model, including flange 1 and be connected to flange
The circular pedestal 2 in 1 one end, pedestal 2 is made up of elastomeric material, and the described middle part of pedestal 2 is provided with the deformation of deformation in the axial direction
Portion 21, the described side of deformations 21 is provided with least two circumferentially spaced corpus unguis 3, the described axial direction side of deformations 21
Make the enlarged-diameter of corpus unguis 3 or contracting to by active force deformation, round base 2 is fixed by flange 1, it is described under external force
The deformation in the axial direction of deformations 21 of pedestal 2, due to being acted on for round base 2 and along axis, makes the deformation of deformations 21 uniform, i.e.,
Open corpus unguis 3 or close up uniform, high precision, axiality are high when making clamping, and processing thin-walled parts are unlikely to deform, and lead in addition
Cross the deformation energy of pedestal 2 and larger dynamics is formed in less stroke, it is ensured that the stability of clamping.Described pedestal 2 is by elasticity
Steel is made, and with linear deformation quantity, and physical life is long.
Described pedestal 2 includes the fixed part 22 being connected with flange 1, and described deformations 21 are arranged in fixed part 22,
It is connected with flange 1 by fixed part 22, realizes the fixation of pedestal 2, during by axial force, deformations 21 prolongs axial direction on pedestal 2
Deformation, and because described deformations 21 include being arranged on the step-like annulus 23 that outer is connected with fixed part 22, by setting
Step-like annulus 23 can change the deformation quantity of deformations 21, realize that pedestal 2 realizes more effective uniform deformation, and the present embodiment
In the cross sectional shape of step-like annulus 23 be trapezoidal, more conducively one deformation in direction.
Fixture also include with pedestal 2 away from the side of corpus unguis 3 be connected to drive the drive rod of the deformation of pedestal 2, described base
Seat 2 is removably connected with connecting rod 5, and the chute 51 slided for drive rod is provided with described connecting rod 5, can by connecting rod 5
The fixation of connecting rod 5 and pedestal 2, the driving pedestal 2 for enabling drive rod to stablize, it is ensured that stress equalization and shape are realized in dismounting connection
Become uniform.
Described deformations 21 are provided with raised 24 corresponding with corpus unguis 3, and described projection 24 detachably connects with corpus unguis 3
Connect, the deformation quantity of corpus unguis 3 can be changed by raised 24 convenient installations and raised 24 width and height, realize to the difference of corpus unguis 3
The design of deformation quantity.Described corpus unguis 3 is both connected on an annular ring 4, is realized multiple unification Fast Installations of corpus unguis 3 and be can guarantee that
The accurate installation site of corpus unguis 3.The described cross section of corpus unguis 3 is sector, not only can guarantee that outer ring and workpiece be stably connected with and
