Abstract
The utility model provides a three-jaw combination chuck which not only can realize the self-centering, but also can realize the adjustment of a single jaw aiming at the shape of workpieces, so as to ensure the clamping of irregular workpieces. The three-jaw combination chuck comprises a chuck body, three jaws and a wire coiling, wherein, the wire coiling is arranged in the chuck body, the three jaws are respectively arranged at the runner of the chuck body and are respectively meshed with the wire coiling; the wire coiling is meshed with a conical gear embedded at the chunk body. The three-jaw combination chuck is characterized in that the three jaws respectively comprise a basic jaw, screw rods are respectively arranged in the basic jaws, and top jaws are respectively arranged at the runners of the basic jaws to be meshed with the screw rods.
Description
(1) technical field
The utility model relates to the machine tooling frock, is specially three-jaw composite chuck.
(2) background technology:
Existing three-jaw composite chuck is a three-jaw self-centering chuck.It drives the parcel rotation by angular wheel, does equidistant moving thereby make three claws be driven along disk body I-shaped groove direction by the parcel flat thread, realizes three claws self-centering clamping workpiece radially.The shortcoming of this claw is exactly the workpiece that it can only effectively clamping rule, can't clamp irregular workpiece, so the scope of application is narrow.
(3) summary of the invention
At the weak point of existing common three-jaw self-centering chuck, the utility model provides a kind of three-jaw composite chuck, and it both can realize self-centering, can realize the monodactyle adjustment at the shape of workpiece again simultaneously, guarantees the clamping to irregular workpiece.
It is realized by following scheme: it comprises disk body, three claws, parcel, described parcel is installed in the described disk body, described three claws are installed on the chute of described disk body respectively and mesh with described parcel respectively, described parcel and the angular wheel engagement that is embedded in described disk body, it is characterized in that: described three claws comprise basic pawl respectively, be respectively arranged with screw mandrel in the described basic pawl, the top pawl is installed on the chute of basic pawl respectively and meshes with described screw mandrel.
The utility model adopts after the said structure, claw changes the divergence type claw of being made up of basic pawl, top pawl into, engaged transmission by three basic pawls and parcel, holding workpiece realizes self-centering, the divergence type claw is realized the independent adjustment of the basic relatively pawl of top pawl, though regular like this or irregular workpiece, all effectively clampings, and applicable scope is wider.

Fig. 1 is a front view of the present utility model
Fig. 2 is the cutaway view of the utility model left view and the schematic diagram of spanner 8.
(5) specific embodiment
See Fig. 1, Fig. 2, the utility model comprises disk body 4, three claws, parcel 3, parcel 3 is installed in the disk body 4, three claws be installed on respectively the chute of disk body 4 and respectively with parcel 3 engagements, parcel 3 and angular wheel 2 engagements that are embedded in disk body 4, three claws comprise basic pawl 5 respectively, are respectively arranged with screw mandrel 6 in the basic pawl 5, top pawl 7 is installed on the chute of basic pawl 5 respectively and meshes with screw mandrel 6, and 1 is gland.
Below in conjunction with accompanying drawing the course of work of the present utility model is described: spanner 8 is inserted in the angular wheel 2 end square holes rotate, drive parcel 3 rotations, when parcel 3 rotates, by parcel 3 flat threads, make three basic pawls interlocks, advance and retreat synchronously, self-centering clamping or unclamp workpiece.When the claw single action is adjusted: with rotating in the spanner 8 insertion screw mandrels 6 end square holes, drive top pawl 7 and move, realize the adjustment of the corresponding chuck of single claw clamping face Clamping Center along disk body 4 I-shaped groove direction straight lines.Contrast common three-jaw self-centering chuck, the three-jaw composite chuck novel structure, easy to use, be applicable to the centering clamping of complex appearance workpiece, particularly when the batch machining of eccentric work piece, utilize the characteristic of claw single action, after the single action debugging top pawl centering workpiece centre, utilize the self-centering function of this chuck, realize in batches self-centering clamping fast.
Claims (1)
1, three-jaw composite chuck, it comprises disk body, three claws, parcel, described parcel is installed in the described disk body, described three claws are installed on the chute of described disk body respectively and mesh with described parcel respectively, described parcel and the angular wheel engagement that is embedded in described disk body, it is characterized in that: described three claws comprise basic pawl respectively, are respectively arranged with screw mandrel in the described basic pawl, and the top pawl is installed on the chute of basic pawl respectively and meshes with described screw mandrel.
