Abstract
The invention provides a self-closing chuck, comprising chuck body, claw. On the chuck body there are claw grooves and claws are set in claw grooves. On the claw wire coiling accepting output force of driving mechanism is set and said claw is connected with the head end face of wire coiling in screw thread. On the side face or the back face of said chuck body there is a ring tooth and a connecting plate connected with the wire coiling is set on the chuck. On the position corresponding with the ring tooth on said connecting plate tool holes are set. The wire coiling in invention is used as driving part to accept the output force of driving mechanism. In clamping operation, as the chuck body is rotated claws are driven synchronization centripetal movement to clamp workpeice tightly so that in manufacturing process the chuck body, claws and the workpeice can obtain rotary inertia with reversed direction to driving mechanism to realize self-closing. In the positive manufacturing process, workpeice is clamped tightly more and more so that the workpeice can not be loosened and the usage is more reliable and safer.
Description
Technical field
The present invention relates to a kind of chuck.
Background technology
In the prior art, chuck comprises disk body, the claw of chuck, is provided with parcel in the disk body, and the front end face of parcel is threaded with claw, and the rear end face of parcel is provided with screw thread, and in the chuck, disk body is a driving link of accepting the driving device power output.During operation, utilize the instrument with parcel rear end face threaded engagement, rotate parcel, make the claw motion that is threaded with parcel to clamp or to loosen workpiece.This chuck the time does not have self-tightening power in work, and jaw might become flexible and weakens clamping to workpiece when running into fortuitous event.
Summary of the invention
Self-energized chuck that can self-tightening when technical problem to be solved by this invention provides the work of a kind of forward.For this reason, the utility model is by the following technical solutions: it comprises disk body, claw, disk body is provided with the claw groove, claw is located in the claw groove, described chuck is provided with the parcel of accepting the driving device power output, and described claw is threaded with the front end face of parcel, and the side of described disk body or rear end face have a circle tooth, described chuck is provided with the terminal pad that links to each other with parcel, and described terminal pad is provided with tooling hole in the position with respect to a described circle tooth.Owing to adopt technical scheme of the present invention, parcel is accepted the driving device power output as driving link, thereby when clamp operation, drive claw and make synchronously entad motion clamping work pieces by rotating disk body, make that in process disk body, claw and workpiece can obtain the rotary inertia with the switched in opposite of driving device, realize self-tightening, in the forward process, workpiece is pressed from both sides tighter and tighter, and the unlikely workpiece that causes is loosening, uses more reliable and secure.

Fig. 3 is the A-A cutaway view of Fig. 2.
Fig. 4 is the B-B cutaway view of Fig. 2.
The specific embodiment
With reference to accompanying drawing.The present invention includes disk body 1, claw 2, disk body is provided with claw groove 11, claw is located in the claw groove, described chuck is provided with the parcel 4 of accepting the driving device power output, described claw is threaded with the front end face of parcel, the rear end face of described disk body has a circle tooth 12, and described chuck is provided with the terminal pad 6 that links to each other with parcel, and described terminal pad is provided with tooling hole 61 in the position with respect to a described circle tooth.
The tooth of disk body rear end face is the umbrella tooth, is provided with the instrument that cooperates with described tooth in the described tooling hole, and it is a bevel gear 5 in the present embodiment, and it is axially spacing by lining 8 at it, is provided with the handle hole of instrument at the outboard end of bevel gear, and this handle hole is the quartet connection hole.Like this, not only more convenient in operation, bevel gear is also more reliable with being connected of disk body.In the enforcement, also can consider described bevel gear 5 is not installed in the chuck, and, insert tooling hole in use and cooperate the driving disk body to rotate with the umbrella tooth of disk body as outer allotment of labor's tool that cooperates with chuck.
Described parcel is in the disk body, parcel be provided with positioning step 41, described chuck is provided with to be connected and cooperates back-up ring 3 to the parcel axial limiting with described step 41 on the disk body.Drawing reference numeral 9 is for connecting the screw of disk body and back-up ring 3.
Described terminal pad is connected with parcel by screw 7, and the pull bar 10 that is connected with driving device is installed on terminal pad, and like this, parcel is connected with driving device by terminal pad, becomes the driving link of accepting the driving device power output.
Tooth on the described disk body also can be located at the disk body side, and this tooth can be common helical teeth, also can be worm-gear toothing or arc tooth.
The front end face of parcel has the flat thread curve, and the rear end face of claw is connected with this flat thread, and claw is by disk body motion clamping work pieces in contrast to the rotation of machine tool chief axis rotation direction and entad.When driving the lathe rotation, because parcel is a driving link, disk body, claw and workpiece are Passive parts, and disk body, claw and workpiece can produce and machine tool chief axis rotates reverse rotating torque, thereby it is tighter that workpiece is held.
Claims (6)
