In a preferred technical scheme, the positioning plate is inserted into the double-claw cylinder and connected with an external manipulator.

In a preferred technical scheme, the front end of the connecting plate is provided with a claw body.

In a preferred technical scheme, inclined holes for sliding insertion of the pin are respectively formed in two sides of the top surface of the positioning plate, and the lower ends of the inclined holes are communicated with the straight grooves.

In a preferred technical scheme, the inclined hole port on the top surface of the positioning plate is kept coincident with the positioning hole port on the bottom of the connecting plate.

The beneficial effects of the utility model are as follows:

1. the pin columns on two sides slide out towards the top along the inclined direction, and the two pin columns are respectively inserted into the corresponding positioning holes so as to be similar to a wedge-shaped insertion design for connecting the assembly positioning plate and the connecting plate, thereby ensuring the assembly and the fixation between the positioning plate and the connecting plate and facilitating the clamping of workpieces by the claw bodies.

2. When the claw body is replaced, the knob is reversely rotated, the control end block moves downwards, the pins on the two sides are separated from the positioning holes, and the connecting plate can be directly detached, so that the operation is convenient.

To sum up, through the quick change structure that this scheme provided, the clamping jaw that has solved different specifications changes comparatively loaded down with trivial details, influences machining efficiency's problem, with the help of wedge complex relation of connection, can accomplish clamping jaw dismouting rapidly, the dismouting process of clamping jaw is reversible completely to need not with the help of external tool, both can reduce staff's working strength, also can save time, improves whole machining efficiency.

In the figure: 1. a double-claw cylinder; 2. a positioning plate; 3. a connecting plate; 4. a claw body; 5. a straight groove; 6. a threaded column; 7. an end block; 8. a pin; 9. a connecting column; 10. positioning holes; 11. and (5) an inclined hole.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

In this embodiment, referring to fig. 1-2, a quick-change structure for a clamping jaw includes a double-jaw cylinder 1, two positioning plates 2 and a connecting plate 3, wherein the positioning plates 2 are inserted into the double-jaw cylinder 1 and connected with an external manipulator, and a jaw body 4 is disposed at the front end of the connecting plate 3.

Straight flute 5 is reserved in the inside of locating plate 2, and the bottom threaded connection of locating plate 2 has screw thread post 6, and in the top of screw thread post 6 extends to straight flute 5, the top of screw thread post 6 was connected with end piece 7 through bearing part rotation, and the lower extreme of screw thread post 6 is provided with the knob, drives screw thread post 6 through rotating this knob and rotates, and at this moment, end piece 7 of screw thread post 6 upper end does not follow the commentaries on classics.

Two connecting columns 9 are hinged to the end block 7, the connecting columns 9 are arranged on two symmetrical sides in a split mode, pin columns 8 are movably mounted at movable ends of the connecting columns 9 respectively, the end block 7 is controlled to ascend and descend in the straight groove 5 in a threaded screwing mode, the pin columns 8 on two sides are rotationally connected with the end block 7 through the connecting columns 9, inclined holes 11 for sliding insertion of the pin columns 8 are formed in two sides of the top surface of the positioning plate 2 respectively, and the lower ends of the inclined holes 11 are communicated with the straight groove 5. When the end block 7 is lifted upwards in the straight slot 5, the pins 8 on both sides can respectively extend upwards from the inclined holes 11 in an inclined direction.
