A kind of clamping jaw of dimensions may be only available for warp in thin-wall part or differ within the scope of ± 1.5mm through size with clamping jaw outside, guarantor
Card thin-wall part can come into full contact with clamping jaw, and protection thin-wall part will not be crushed and be deformed by clamping jaw, influence machining accuracy.
Preferably, the clamping jaw is consistent with the quantity of collet, if there are three the folder points on collet, corresponding clamping jaw is equipped with three
It is a.
Preferably, the fixing seat of the clamping jaw is outstanding is equipped with limited block.
Preferably, the fixing seat is equipped at least two through-holes, enhances fixing intensity of the clamping jaw on collet, prevents from pressing from both sides
It is displaced between pawl and collet.
It can be with the utility model has the beneficial effects that devise a kind of dedicated clamping jaw of thin-wall part, between clamping jaw and thin-wall part
Realize face contact, during clamping processing, clamping jaw will not be caused to crush and be deformed to the forming surface of thin-wall part, will not influence
The roughness and precision on surface, the design of clamping jaw taper and cooperate the steel of 30CrMnSIA material that can allow clamping jaw and thin-walled
Clamping force between part reaches maximization, will not be displaced during thin-wall part reprocessing；In addition, the clamping jaw of the utility model
For the thin-wall part of flow line production, the thin-wall part for clamping different specification size, guarantee pair are corresponded to the clamping jaw of different size
Thin-wall part realizes full-enclosed clamping or stretching；Trial effect is good on lathe, the fixing end surfacing of forming thin-walled part
Smooth, without any bad destruction, deformation is greatly reduced.

Specific embodiment
It should be pointed out that the fixture that the utility model is previously mentioned is turning attachment, turning attachment itself has clamping and unclamps
Power, the utility model by be exactly turning attachment itself power be clamped work.
As shown in Fig.1 and Fig.2, a kind of to contain soft pawl, including chuck 1, collet 2, clamping jaw entirely for the novel of clamping thin-wall part
3；The collet 2 is equidistant to be mounted on chuck 1, and fixture is formed；It is characterized in that being detachably and fixedly provided with folder on the collet 2
Pawl 3；The clamping jaw 3 is integrally machined by fixing seat 3-1 and arc clamp arm 3-2, is equipped with and is used for and collet on fixing seat 3-1
The fixed through-hole of 2 phases；As shown in figure 3, the arc outer surface clamp arm 3-2 on the clamping jaw 3 is pyramidal structure, taper be 0≤α≤
0.5 °, thin-wall part not only more easily can be clamped or be removed by pyramidal structure, moreover it is possible to be enhanced between clamping jaw 3 and thin-wall part
Tensile force；Arc clamp arm 3-2 inner surface on the clamping jaw 3 is wide-mouth structure, and wide-mouth angle is 0-0.3 ° (containing zero degree), accordingly
, the design structure of wide-mouth is not only convenient for the installation and removal of thin-wall part, additionally it is possible to enhance being engaged between collet 2 and thin-wall part
Power；The inner wall of the clamping jaw 3 is outstanding at fixing seat 3-1 to be equipped with chuck 3-3；When being clamped fixed to thin-wall part,
It limits pipe fitting and extend into the length in clamping jaw 3；The material of the collet 2 is 30CrMnSIA, and the steel is in stress with certain
Deformability, when pipe fitting is mounted on clamping jaw 3, during being clamped to thin-wall part, the deformability which has can
Pipe fitting is wrapped entirely and is firmly engaged, the clamping force that thin-wall part molded surface is subject to is uniformly and to act on the stress surface on pipe fitting big
(thin-wall part is that packet is fixed entirely by clamping jaw 3).
Further, the clamping jaw 3 is equipped at least one specifications and models, is matched for different size of thin-wall part
Replacement, a kind of clamping jaw 3 of specifications and models are only used for a kind of thin-wall part of specification, guarantee that thin-walled material can sufficiently connect with clamping jaw 3
Touching, protection thin-wall part will not be crushed by clamping jaw 3, influence machining accuracy；During clamping jaw 3 are installed, clamping jaw 3 and collet 2
Quantity is consistent, if there are three the folder points on collet 2, there are three corresponding clamping jaw 3 is set；The fixing seat 3-1 and collet of the clamping jaw 3
Outstanding at 2 interfaces to be equipped with limited block 4, enhancing clamping jaw 3 is fixed on the fixing intensity on collet 2, prevents in processing thin-wall part
When be displaced, influence machining accuracy；The fixing seat 3-1 is equipped at least two through-holes, enhances clamping jaw 3 in collet 2
On fixing intensity, prevent from being displaced between clamping jaw 3 and collet 2.
Such as Fig. 4, shown in Fig. 5, the utility model devises a kind of full double team pawl 3, passes through the arc clamp arm 3-2 of pyramidal structure
Thin-wall part is fixed, thin-wall part can be firmly fixed on lathe by full packet, then be processed；The clamping jaw 3 of the utility model
Particularly suitable for batch production, the specification of thin-wall part is consistent, after the thin-wall part completion of processing with a batch specification, replaces clamping jaw 3, into
The thin-wall part of row next group specification is processed；Pay special attention to, the specification of the utility model clamping jaw 3 need to be matched with thin-wall part specification
(inner surface or the taper of outer surface and the inner hole or outer diameter of thin-wall part of 3 arc clamp arm 3-2 of clamping jaw matches).
