Abstract
The invention relates to a six-jaw independent chuck, which comprises a chuck body, six jaws, six lead screws and six chuck posts, wherein the six jaws are connected with the chuck body through jaw chutes; the six lead screws are arranged in the chuck body through thread connection, and are positioned with the chuck body through the six chuck posts; two ends of each of the six lead screws are provided with threads and correspondingly connected with the six jaws in an engagement mode; the six jaws are uniformly distributed at an interval of 60 degrees along the chuck body; and the chuck body is provided with the jaw chutes. The six-jaw independent chuck has a simple, compact and rational structure; and compared with a common four-jaw independent chuck, the six-jaw independent chuck has the advantages of rational structure, remarkable improvement of carrying capacity, capacity of clamping a workpiece more than two times heavier than the conventional workpiece, and high-speed heavy load of a large-sized workpiece.
Description
Technical field
The present invention relates to a kind of six-jaw independent chuck, specifically, be a kind of independent chuck of improvement with the matching used frock of lathe.
Background technology
Existing independent chuck mostly is chuck, and four claws are uniform by 90 °, during holding workpiece, have the problem that the monolithic claw bears the workpiece total weight on the extreme position, make four-jaw chuck only can use under the low speed light condition.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, can have two to bear the total weight of workpiece at an arbitrary position, can guarantee the six-jaw independent chuck of high-speed overload running with upper clipping claw thereby provide a kind of.
According to technical scheme provided by the invention, six-jaw independent chuck comprises chuck body, six claws, six roots of sensation screw mandrel and six roots of sensation card posts, six claws are connected by the claw chute with chuck body, six roots of sensation screw mandrel is located in the chuck body with being threaded, locate by six roots of sensation card post between described six roots of sensation screw mandrel and the described chuck body, screw thread is made at six roots of sensation screw mandrel two, with six corresponding being connected with a joggle of claw.
Described six claws are uniform by 60 degree along described chuck body.Be shaped on the claw chute on the described chuck body.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Contrast common four-jaw chuck, six-jaw independent chuck is rational in infrastructure, and bearing capacity obviously improves, and maximum grip workpiece weight can realize the high-speed overload load of large-scale workpiece more than twice.
Description of drawings
Fig. 1 is a structural front view of the present invention.
Fig. 2 is a structure cutaway view of the present invention.
The specific embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
Fig. 1～shown in Figure 2, comprise chuck body 4, six claws 1, six roots of sensation screw mandrel 3 and six roots of sensation card posts 2, six claws 1 are connected by claw worker chute with chuck body 4, six roots of sensation screw mandrel 3 is located in the chuck body 4 with being threaded, locate by six roots of sensation card post 2 between described six roots of sensation screw mandrel 3 and the described chuck body 4, screw thread is made at six roots of sensation screw mandrel 3 two, with six claws, 1 corresponding being connected with a joggle.
Described six claws 1 are uniform by 60 degree along described chuck body 4.Be shaped on the claw chute on the described chuck body 4.
The present invention adopts after the said structure, no matter which angle chuck body rest on, guarantee that all at least two claws are bearing the all-mass of workpiece, the bearing capacity of chuck obviously improves, maximum grip workpiece weight also increases substantially, and can realize the high-speed overload running of large-scale workpiece.
