Abstract

The utility model relates to a box chuck, which comprises a box chuck body (1) and jaws (2). The box chuck is characterized in that the jaws (2) are arranged on two bevel gears of the box chuck body (1) respectively, portions of the jaws (2) contacting with a workpiece to be processed are arc-shaped, and the axis of the workpiece to be processed corresponds to that of the box chuck body (1) after the workpiece to be processed is clamped in the jaws (2). By the aid of the box chuck, a bent pipe workpiece is clamped conveniently and firmly when being processed as stress is even, the shortcoming of difficulty in clamping the bent pipe workpiece during processing is overcome effectively, the operating efficiency and the qualification rate of a turning lathe are improved greatly during processing, and more benefits are created for enterprises.

Description

A kind of two-jaw(ed)chuck

Technical field

The utility model relates to a kind of two-jaw(ed)chuck, particularly a kind of two-jaw(ed)chuck of bent pipe processing usefulness.

Background technology

In the prior art, when processing some bent pipe workpiece (for example Fig. 4), with two pawls of standard, three-jaw and four paws dress all are difficult to clamping.When machined into, will have a strong impact on the efficient and the qualification rate of processing.

The utility model content

To the deficiency that exists on the prior art, the utility model provides a kind of two-jaw(ed)chuck that is applicable to the processing of bent pipe workpiece.

To achieve these goals, the utility model is to realize through following technical scheme:

A kind of two-jaw(ed)chuck comprises two-jaw(ed)chuck body and claw, it is characterized in that: on two umbrella teeth of two-jaw(ed)chuck body claw is set respectively; Said claw and workpiece to be machined contact portion are circular arc, and after workpiece to be machined was clamped in the claw, the axle center of workpiece to be machined was corresponding with the axle center of two-jaw(ed)chuck body.

Above-mentioned a kind of two-jaw(ed)chuck is characterized in that the used material of claw is a cast iron materials.

Above-mentioned a kind of two-jaw(ed)chuck is characterized in that described claw and being connected of umbrella tooth is to be fixedly connected perhaps to removably connect separately.

Above-mentioned a kind of two-jaw(ed)chuck; It is characterized in that the said claw and the mode of removably connecting of umbrella tooth separately are; Be provided with and corresponding slide rail of claw and chute in umbrella tooth inside, be provided with retention device, can not skid off the umbrella tooth when claw is slided at an end of slide rail and chute.

The beneficial effect that the utility model compared with prior art has is: after adopting this two-jaw(ed)chuck; The bent pipe workpiece is adding man-hour; Because stressed even, convenient mounting and clamping is firm, effectively solves the bent pipe workpiece and adds the shortcoming that is difficult to clamping man-hour; Add the operating efficiency and the qualification rate that have improved lathe man-hour greatly, for enterprise creates bigger benefit.

Vertical view when Fig. 5 uses for the utility model.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with the specific embodiment, further set forth the utility model.

Like Fig. 1, shown in 2,3, a kind of two-jaw(ed)chuck comprises two-jaw(ed)chuck body 1 and claw 2, it is characterized in that: on two umbrella teeth 3 of two-jaw(ed)chuck body 1 claw 2 is set respectively; Said claw 2 is a circular arc with the workpiece to be machined contact portion.The material of claw 2 is to be processed by cast iron materials; Claw 2 is with being connected of umbrella tooth 3 is to be fixedly connected perhaps to removably connect separately; Card, 2 with the mode of removably connecting of umbrella tooth 3 separately be to be provided with in umbrella tooth 3 inside and claw 2 corresponding slide rail and chutes; End at slide rail and chute is provided with retention device, can not skid off umbrella tooth 3 when claw 2 is slided.

As shown in Figure 4, be a kind of sketch map of common bent pipe workpiece, its two ports are circular.

As shown in Figure 5; Sketch map during for two-jaw(ed)chuck processing bent pipe workpiece 3; The circular arc contact-making surface of claw 2 and the body of bent pipe workpiece 3 adapt, and after bent pipe workpiece 3 was clamped in the claw 2, the axle center of processed bent pipe workpiece 3 was corresponding with the axle center of two-jaw(ed)chuck body 1.

More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
