Work fixture

Technical Field

The utility model relates to a production technical field especially relates to a frock clamp.

Background

In the manufacturing, traditional frock clamp adopts scissors formula anchor clamps, and scissors formula's anchor clamps can produce certain corner at the in-process of centre gripping, and then produce corresponding shear stress, and simultaneously, the range of stretching of its jack catch of traditional scissors formula anchor clamps is less relatively, can not carry out the clamping to the great article of size and specification.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a problem among the above-mentioned background of effectual solution has proposed a frock clamp, and concrete technical scheme is as follows:

a tool clamp comprises a clamping jaw (1), a slide way (2) in sliding fit with the clamping jaw (1) and a driving device; the driving device comprises connecting rods (3) respectively hinged with the two clamping jaws (1), the two connecting rods (3) are respectively hinged at two ends of a driving rod (4), the two connected connecting rods (3) are parallel to each other, and a driving motor is installed in the center of the driving rod (4) in a matched mode;

the connecting rods (3) are symmetrically arranged at two ends of the clamping jaw (1) and the driving rod (4) in parallel;

the driving rod (4) is rotatably connected with a fixed plate (5) fixed at the center of the slide way (2), and the driving rod (4);

the utility model has the advantages that the device drives the two claws to move oppositely through the rotation of the driving rod, thereby realizing the clamping; and the clamping jaw arranged on the slideway can move transversely to remove the shearing force of the corner, so that the clamping space of the clamping jaw is increased.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural diagram of the present invention.

In the figure: clamping jaw 1, slide 2, connecting rod 3, actuating lever 4, fixed plate 5.

Detailed Description

The technical scheme of the patent is further explained in detail by combining the specific embodiment;

a frock clamp comprises a clamping jaw 1, a slideway 2 in sliding fit with the clamping jaw 1 and a driving device; drive arrangement includes with two clamping jaw 1 articulated connecting rod 3 respectively, connecting rod 3 symmetry parallel arrangement is at the both ends of clamping jaw 1 and actuating lever 4, and two connecting rods 3 articulate respectively at the both ends of actuating lever 4, and two connecting rods 3 after connecting are parallel to each other, 4 central cooperations of actuating lever installation driving motor, actuating lever 4 rotates with fixed plate 5 of fixing at slide 2 center to be connected, actuating lever 4.

The device drives the two claws to move oppositely through the rotation of the driving rod, so as to realize clamping; and the clamping jaw arranged on the slideway can move transversely to remove the shearing force of the corner, so that the clamping space of the clamping jaw is increased.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the invention.
