Being accurately positioned for part is realized with plane and two pitses positioning method, blank is also in the majority with the rib pin taper pin and round pin of floating when positioning,
Claw makes concentric mechanism by oneself in Milling Machining using very few.
The content of the invention
To solve the problem of prior art is present, the present invention provides a kind of self-centering claw directional manual milling drill jig.Should
Fixture solves the problem of blank excircle orientation centering is inaccurate, efficiency is low on Milling Machining center well, in addition also well
The cylindrical positioning of different size range parts is taken into account, while realizing the orientation requirement of Milling Machining.
To achieve the above object, the present invention uses following technical scheme：
A kind of self-centering claw directional manual milling drill jig, including chuck body；Card is provided with described chuck body
Three claws being centrosymmetrically arranged are provided with disk body, chuck body, each claw is bolted an extension arm, lengthened
Arm outer end is anti-pawl；Three claws are connected with the mandrel wedge shape being arranged on inside chuck body, and mandrel center connects with screw rod one end
Connect, the screw rod other end stretches out chuck body and is connected with handle, and screw rod is threadedly coupled with the centre bore of chuck body.
Described mandrel is round table-like, and claw inner end structure matches with round table-like.
It is additionally provided with described chuck body for the angular block and pushing block positioned of part, block and pushing block
It is oppositely arranged, and block and pushing block are arranged in corresponding support using hinging manner；Tune is provided with block and pushing block
Save bolt.
Described extension arm is U-shape structure, and U-shape structure with claw while fix, and another side inwall is provided with anti-skid structure.
Described claw and extension arm is arranged in the guide groove in chuck body.Three guide grooves are mutually 120 ° of distributions.
The rotary pressure plate of fixed workpiece upper end is additionally provided with described chuck body.
The present invention compared with prior art, with advantages below：
The fixture promote close or move back to center with the wedge-shaped claw being connected of mandrel by adjusting the lifting of mandrel
Go out to carry out the three-jaw positioning of part, and by designing extension arm, can be very good to solve blank on Milling Machining center cylindrical fixed
While the problem of position centering is inaccurate, efficiency is low, the cylindrical positioning of different size range parts is also well taken into account, simultaneously
Realize the orientation requirement of Milling Machining.
Further, traditional claw chuck for being usually used in lathe positioning clamping is passed through and improved by the present invention, and increases angular
Position block, realizes the cylindrical part of large scale and clamps and process in the supercentral positioning of Milling Machining, be follow-up claw self-centering
The design popularization and application of milling drill jig provide good mentality of designing and reference.

Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings：
Shown in below figure 1 and Fig. 2, a kind of self-centering claw directional manual milling drill jig of the invention, including chuck body 9；
Three claws 22 for being provided with and being centrosymmetrically arranged on chuck body 1, chuck body 1 are provided with described chuck body 9, each card
Pawl 22 connects an extension arm 23 by bolt 8, and the outer end of extension arm 23 is anti-pawl；Three claws 22 are with being arranged on chuck body 1
The internal wedge shape connection of mandrel 15, the center of mandrel 15 is connected with the one end of screw rod 21, and the other end of screw rod 21 stretches out chuck body 1 and handle
18 are connected, and screw rod 21 is threadedly coupled with the centre bore of chuck body 1.Mandrel 15 is round table-like, the inner end structure of claw 22 and round platform
Shape matches.It is additionally provided with for the angular block 25 and pushing block 10 positioned of part, block 25 and pushes away in chuck body 9
Block 10 is oppositely arranged, and block 25 and pushing block 10 are arranged in corresponding support using hinging manner；Block 25 and pushing block 10
On be provided with regulating bolt.Extension arm 23 is that part is placed in U-shape structure, U-shape structure.Claw 22 and extension arm 23 are respectively provided with
In guide groove in chuck body 9.Three guide grooves are mutually 120 ° of distributions.
Four rotary pressure plates 3 for being used to fix workpiece upper end are additionally provided with chuck body 9.Four rotary pressure plates 3 are uniform
Pressing plate on distribution, rotary pressure plate 3 is pushed down by spring.
The course of work of the present invention is mainly rotation handle 18, and by screw rod 21, transmission belt moving mandrel 15 moves up and down, with core
The claw 22 of axle wedge shape connection is simultaneously close or exit to center, realizes that the positioning of part is clamped and release.To claw in design
Part is improved, and couples an extension arm 23 by bolt 8, and need to only change extension arm 23, without changing core component
Mandrel 15 and claw 22, just can meet the cylindrical positioning of different large scale scope parts, simple to operate, the fixture scope of application
Extensively, scalability is strong.It is angular to part to position by installing position block 25 and pushing block 10 in chuck body 9, prevent zero
Part is rotated, and block 25 and pushing block 10 are coupled using hinging manner, facilitate part to load and unload.
The application method of the present invention is as follows：
