Abstract
The utility model discloses a self-centering chuck in which claw-claw linkage renders work piece clamping a self-centering process and enables convenient and rapid clamping and disassembly through only one adjustment. The chuck comprises a chuck body, claws and a screw rod, wherein, the screw rod is installed on the chuck body, the middle part of the screw rod is restrained by a clamp pillar positioned inside the chuck body, the claws are mounted in a chute of the chuck body and is in meshed connection with the screw rod, the claws total two, and two ends of the screw rod are opposite in spiral direction of threads and are respectively connected with the two claws in a threaded manner.
Description
Technical field
The utility model relates to machine chuck class frock technical field, is specially self-centering chuck.
Background technology
It often is four-jaw chuck that lathe is forced with chuck, each claw is respectively by a leading screw control, be independently between each claw, each clamping, discharging workpieces must be regulated screw mandrel respectively, owing to can not link between the claw, can't self-centering during holding workpiece, so clamping, more time-consuming, the effort of discharging workpieces.
The utility model content
At the problems referred to above, the utility model provides a kind of self-centering chuck, can realize interlock between each claw, can realize self-centering during clamping workpiece, once regulates and can realize clamping and unloading, and is both convenient, quick again.
Its technical scheme is such: it comprises chuck body, claw, screw mandrel, described screw mandrel is installed on described chuck body, the position, intermediate portion is by being positioned at chuck alms bowl card post location, described claw be installed in the chute of described chuck body and and be connected with a joggle with described screw mandrel, it is characterized in that: totally two of described claws, the hand of thread spiral at its two ends of described screw mandrel opposite and respectively with described two claws with being threaded.
In the said structure of the present utility model, a rhizoid bar drives two claws simultaneously, realizes interlock, can self-centering during holding workpiece, simple, quick, thus avoided existing structure, each screw mandrel is only controlled a claw, and claw can't be realized interlock, awkward shortcoming.
Description of drawings
The schematic diagram that Fig. 1 looks for master of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view and partial sectional view;
Fig. 3 is the upward view of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
See Fig. 1, Fig. 2, Fig. 3, the utility model comprises chuck body 1, claw 2,3, screw mandrel 4, screw mandrel 4 is installed on chuck body 1, the position, intermediate portion is by being positioned at chuck body 1 card post 5 location, the hand of thread spiral at screw mandrel 4 two ends is opposite, claw 2,3 be installed in the chute of chuck body 1 and respectively with the two ends of screw mandrel 4 with being threaded.Clamping or when unclamping workpiece is inserted spanner in the screw mandrel 4 end square holes and to be rotated, and drives screw mandrel 4 rotations, when screw mandrel 4 rotates, by the screw thread of the opposite rotation direction in screw mandrel 4 two, makes the synchronous forward and back of claw 2,3 interlocks, realizes clamping or unclamps workpiece.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
