Specific embodiment

For the ease of the understanding of those skilled in the art, the utility model is made further below with reference to embodiment Bright, the content that embodiment refers to not is the restriction to the utility model.

As shown in Figure 1 to Figure 3, a kind of compact clamping device, including mounting base 1 and the positioning table for being installed in mounting base 1 11, the mounting base 1 is installed with fixed plate 2, is opened in fixed plate 2 and interconnected limiting slot 21 and rotation slot 22, described Positioning table 11 is connected with the first clamp jaw 3 and the second clamp jaw 4, and first clamp jaw 3 includes clamping section 31, linkage portion 32 and from the limited block 33 that 32 side of linkage portion is extended, the fixed plate 2 is installed with the first of driving the first clamp jaw 3 movement Driving device 5, mounting base 1 are installed with the second driving device 6 of driving the second clamp jaw 4 movement.

The compact clamping device of the present embodiment, in actual use, first driving device 5 and the second driving device 6 start simultaneously, and the first clamp jaw 3 is because of the angle arrangement of first driving device 5 and being obliquely installed for linkage portion 32, so that being inserted in The first forward slip of limited block 33 in limiting slot 21, carries out rotational motion after slipping into rotation slot 22, so that the first clamp jaw 3 Clamping section 31 move upwards and complete opening action, and the second clamp jaw 4 is then directly pushed forward opening, and workpiece is put at this time, first Driving device 5 and the second driving device 6 are again started up, and because the shape of limited block 33 is arranged, limited block 33 can not be pulled at once In limiting slot 21, the meeting of limited block 33 first rotation, which allows limited block 33 to be aligned with limiting slot 21, can be just returned in limiting slot 21, and the The clamping section 31 of one clamp jaw 3, which then first moves downward then just to move backward, completes to fasten clamping effect, and the second clamp jaw 4 is then straight Pusher clamping is connect, 3 simple structure of the first clamp jaw, which is realized, opens snap action, and it is more that adaptability can more extensively clamp workpiece, flexibly Property height facilitate the multi-angle of workpiece to be put into, reduce cooperation and be put into the complexity of workpiece device, it is practical.

In the present embodiment, the fixed plate 2 offers the accommodation groove 23 for being connected to limiting slot 21 and is installed in accommodation groove 23 Interior elastic component 24, the elastic component 24 are connected to limiting slot 21, and the design of elastic component 24 facilitates auxiliary the first driving dress Set when 5 resets clamp and limit the motion profile of the first clamp jaw 3, preferably cause the first clamp jaw 3 to be when being pulled back be first to Movement clamps backward again for lower movement, and simple structure is realized, manufacturing cost is reduced.

In the present embodiment, the front cross sectional shape of the limited block 33 is ellipse, and ellipse preferably limits the first folder The advance of tight pawl 3 is rotated further by or rotates to be retreated again, simply cleverly completes the clamping and release movement of the first clamp jaw 3, the One clamp jaw 3 moves upwards so that opening that opening is bigger, and more convenient product is placed and taken out, and versatility is high.

In the present embodiment, the quantity of the fixed plate 2 is two or more, which is arranged in installation Seat 1, multiple settings of fixed plate 2 improve the overall stability of the first clamp jaw 3, improve clamping force, prevent from producing in process The loosening of product causes processing defect occur, improves and clamps quality.

In the present embodiment, the first driving device 5 is installed with the first drive rod 51 for being connected to linkage portion 32, this first Included angle between the center line and horizontal plane of drive rod 51 is 20~28 degree, and strength is preferably completed in the design of the angle Transmitting so that the first clamp jaw 3 obtain be pushed forward, the power of post-tensioning or rotation it is not too big, otherwise limiting slot 21 and rotation Slot 22, which constantly will appear by collision more energetically, grinds big situation, so that the subsequent pinching action of the first clamp jaw 3 is not flexible It is unstable.

In the present embodiment, second driving device 6 is installed with the second drive rod 61, which passes through positioning Platform 11 is connected to the second clamp jaw 4, and the second drive rod 61 gives the second clamp jaw 4 power directly through positioning table 11, before completion The movement with post-tensioning is pushed away, directly through manufacturing cost is reduced, the Simple Design of the second clamp jaw 4 is convenient for quick pre- folder when clamping Tightly, guarantee that the clamping positioning of the first clamp jaw 3 is more acurrate.
