Description
Technical field
The utility model relates to a kind of rear pull type chucks, more particularly to a kind of three jaw self-centering rear pull type chucks.
Background technique
In the prior art, for the turnery processing of some easily-deformable aluminum component shell class products, standard rear pull type card is used
Disk folder holds workpiece blank outer circle, be easy to cause the deformation of workpiece, and the precision that product is not achieved in the hole or outer circle after leading to processing is wanted
It asks.
Utility model content
The utility model is directed to above-mentioned defect existing in the prior art, provides a kind of three jaw self-centering rear pull type chucks,
To solve that workpiece is be easy to cause to deform, the problems such as required precision is not achieved in the hole of processing.
In order to reach above-mentioned technical purpose, the utility model uses following technical scheme:
A kind of three jaw self-centering rear pull type chucks, including clamp body, pedestal, pull rod, drive disk, component pull rod and clamping jaw；
Clamp body and pedestal are connected by screw to；One end of drive disk passes through adapter connecting rod, the other end interlocking point of drive disk
Power pull rod, component pull rod pass through connection axis connection clamping jaw.
Component pull rod is equipped at three as a further improvement of the utility model,.
Clamping jaw is equipped at three as a further improvement of the utility model,.
Clamping jaw is elastic material as a further improvement of the utility model,.
The angle between clamping jaw is into 20-60 ° as a further improvement of the utility model,；It is preferred that angle is 30 °.
Clamping jaw two sides are respectively equipped with positioning seat as a further improvement of the utility model,.
Positioning seat is the inclined plane shape matched with clamping jaw as a further improvement of the utility model,.
Compared with prior art, the utility model has the following beneficial effects:
1, clamping jaw retaining part will not cause workpiece to have any deformation clamping force is excessive, and the product after processing can be with
Reach cutting precision requirement to greatest extent.
2, it in clamping process while automatic capturing workpiece centre, drives workpiece to be adjacent to positioning support face backward, guarantees three
Point location it is accurate and reliable.
3, elastic clamping jaw, clamping opening can automatically return to original state during loosening.

Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Referring to attached drawing 1-3, the present embodiment provides a kind of three jaw self-centering rear pull type chucks, including clamp body 1, pedestal 2, drawing
Bar 3, drive disk 4, component pull rod 5 and clamping jaw 6；Clamp body 1 and pedestal 2 are connected by screw to；One end of drive disk 4 passes through switching
First 8 connecting rod 3, the other end of drive disk 4 rabbet component pull rod 5, and component pull rod 5 connects clamping jaw 6 by connecting shaft 9.
Component pull rod 5 is equipped at three；Clamping jaw 6 is equipped at three；Clamping jaw 6 is elastic material；Angle 7 between clamping jaw 6 is
30°；6 two sides of clamping jaw are respectively equipped with positioning seat 10；Positioning seat 10 is the inclined plane shape matched with clamping jaw 6.
Working principle: 3 stress of pull rod moves downward, and drives drive disk 4, three punishment power pull rod 5 of the connection of drive disk 4, component
Pull rod 5 pulls elastic clamping jaw 6 by coupling spindle 9, and clamping jaw 6 moves simultaneously to the left, the clamping opening under the effect of 10 double inclined plane of positioning seat
It shrinks, to clamp workpiece, in clamping process, since clamping jaw 6 is to move synchronously at three, it is possible in automatic capturing workpiece
The heart drives workpiece to move to the left in 6 clamping process of clamping jaw, guarantees 3 points of workpiece and is adjacent to positioning surface, final to realize workpiece positioning
It clamps.Elasticity clamping jaw 6 in clamping process, under the action of double inclined plane, shrink to realize the positioning to workpiece by clamping opening at three
And clamping action, original state can be automatically returned to by loosening rear clamping opening.
Compared with prior art, self-centering rear pull type chuck provided in this embodiment has the advantage that the 1) clamping of clamping jaw 6
Position will not cause workpiece to have any deformation clamping force is excessive, and the product after processing can reach cutting to greatest extent
Required precision；2) it in clamping process while automatic capturing workpiece centre, drives workpiece to be adjacent to positioning support face backward, guarantees three
Accurate and reliable 3) the elastic clamping jaw 6 of point location, clamping opening can automatically reply cause original state during loosening.
Specific embodiment of the utility model is described in detail above, but it is merely an example, this is practical new
Type is not restricted to particular embodiments described above.To those skilled in the art, any pair of the utility model carries out
Equivalent modifications and substitution also all among the scope of the utility model.Therefore, in the spirit and model for not departing from the utility model
Lower made equal transformation and modification are enclosed, should all be covered in the scope of the utility model.
