Abstract
The utility model discloses a kind of CNC machine three-jaw positioning chuck, including chuck, three claws being arranged on chuck, described claw includes that a clamping block and a fixed block, the outer wall both sides of described clamping block respectively arrange two slide blocks；The lower surface opening of described fixed block, opening inwall correspondence slide position offers chute, and clamping block is movably installed in the chute that fixed block opening is offered by the slide block of both sides；Clamping block lower surface protrudes from fixed block, runs through fixed block and clamping block is provided with two positioning screws outside fixed block, and the other end of positioning screw passes through nut check.This utility model is adding man-hour, when workpiece is pulled out one section in chuck by needs, need to unclamp claw, without from new definition, as long as pull-out positioning screw, now clamping block just can be relatively fixed block and seesaws, after material pull-out certain length, locking positioning screw rod can complete front and back to fix again, simple and convenient, improves work efficiency.
Description
Technical field
This utility model relates to a kind of CNC machine three-jaw positioning chuck.
Background technology
Circular bar workpiece is typically by three-jaw Self-position chuck clamping, and centering is fast, can effectively play bar
Rock.But, adding man-hour, after bar is fixed gripping, if bar length is inadequate, needing to draw
Go out bar, it is common practice that unclamp scroll chuck, then pulled out by bar.The drawback of this mode is to weigh
New cutter positioning, and bar probably produces and rocks, and the most repeatedly clamps, until bar exists
Do not rock during rotation, and clamping expends strength, uses inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is to provide one can complete work without unclamping scroll chuck
The regulation of part length, and can the CNC machine three-jaw positioning chuck of workpiece of clamping triangle class.
This utility model is achieved through the following technical solutions: a kind of CNC machine three-jaw positioning chuck,
Including chuck, three claws being arranged on chuck, described claw includes a clamping block and a fixed block, institute
The outer wall both sides stating clamping block respectively arrange two slide blocks；
The lower surface opening of described fixed block, opening inwall correspondence slide position offers chute, clamps block
It is movably installed in the chute that fixed block opening is offered by the slide block of both sides；
Clamping block lower surface protrudes from fixed block, runs through fixed block and clamping block is provided with two and determines outside fixed block
Position screw rod, the other end of positioning screw passes through nut check.
As preferred technical scheme, the bottom surface of described clamping block offers more than one draw-in groove, respectively blocks
Groove is arranged side by side.
As preferred technical scheme, the length of described clamping block is more than the length of fixed block, the two of clamping block
End stretches out in the both sides of fixed block respectively, and workpiece is installed between three pieces of clamping blocks and compresses.
As preferred technical scheme, described clamping block and curved of work piece interface.
As preferred technical scheme, described clamping block extends transversely through and is provided with more than one through hole, location
Screw rod is through through hole to the other end of fixed block.
The beneficial effects of the utility model are: this utility model is adding man-hour, when needs by workpiece in chuck
When pulling out one section, need to unclamp claw, without from new definition, as long as pull-out positioning screw, now clamp
Block just can be relatively fixed block and seesaw, and after material pull-out certain length, locking positioning screw rod can be complete again
Fix before and after one-tenth, simple and convenient, improve work efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below by right
In embodiment or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that below,
Accompanying drawing in description is only embodiments more of the present utility model, for those of ordinary skill in the art,
On the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of embodiment 1 of the present utility model；
Fig. 2 is the structural representation of embodiment 2 of the present utility model.
Detailed description of the invention
All features disclosed in this specification, or disclosed all methods or during step, except mutually
Beyond the feature repelled mutually and/or step, all can combine by any way.
Any feature disclosed in this specification (including any accessory claim, summary and accompanying drawing), removes
Non-specifically describes, all can be by other equivalences or have the alternative features of similar purpose and replaced.That is, unless
Narration especially, each feature is an example in a series of equivalence or similar characteristics.
Embodiment one
Including chuck, three claws being arranged on chuck 1, described claw includes that a clamping block 6 and is solid
Determining block 3, the outer wall both sides of described clamping block 6 respectively arrange two slide blocks 5；The lower surface opening of described fixed block 3,
Opening inwall correspondence slide position offers chute, and clamping block 6 is movably installed in by the slide block 5 of both sides
In the chute that fixed block 3 opening is offered；Clamping block 6 lower surface protrudes from fixed block 3, and fixed block 3 is outside
Running through fixed block and clamping block is provided with two positioning screws 4, the other end of positioning screw 4 is locked by nut 2.
The length of clamping block 6 stretches out in fixed block 3 respectively more than the length of fixed block 3, the two ends of clamping block 6
Both sides, workpiece is installed between three pieces of clamping blocks and compresses, owing to the length of clamping block is more than the length of fixed block
Degree, therefore can relatively pull out longer distance by clamping block, complete the regulation of bar length.
Clamping block 6 and curved of work piece interface, owing in arc surface, therefore can fit tightly with bar,
Clamping effect is more preferable.
Clamping block 6 extends transversely through and is provided with more than one through hole, and positioning screw is through through hole to fixed block
The other end.This through hole is mainly used for the interspersed use in positioning screw location, after Workpiece length has regulated,
Can complete in positioning screw is inserted into through hole again to fix,
Embodiment two
Owing to offering draw-in groove 7 in clamping block 6 bottom surface, therefore the three of the workpiece of triangle angle can be snapped into
In the draw-in groove of three clamping blocks, complete the clamping of the workpiece of special shape.
The beneficial effects of the utility model are: this utility model is adding man-hour, when needs by workpiece in chuck
When pulling out one section, need to unclamp claw, without from new definition, as long as pull-out positioning screw, now clamp
Block just can be relatively fixed block and seesaw, and after material pull-out certain length, locking positioning screw rod can be complete again
Fix before and after one-tenth, simple and convenient, improve work efficiency.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is also
It is not limited to this, any change expected without creative work or replacement, all should contain in this practicality new
Within the protection domain of type.Therefore, protection domain of the present utility model should be limited with claims
Protection domain is as the criterion.
