The further construction features of the present invention includes:
1. all of support of this fixture all adopts plane and two pits to position, and both ensure that positioning precision, connects convenient and reliable again;
2. this fixture utilizes two V-blocks (11) to position, and improves the rigidity of location clamping;
3. be attached by studs (7) between piston rod (7) and the wedge (10) of hydraulic cylinder, easy to connect reliably, it is also possible to be suitably adjusted;
4. wedge (10), connecting rod 1(12) between be connected to connection sheet (15), when hydraulic cylinder piston rod (7) is retracted, can pull connect sheet (15), it is ensured that fixture reliable reset;
5. connecting rod 1(12), connecting rod 2(13) and bearing pin (14) between all circumferentially positioned employing square opening realize, it is ensured that the reliable delivery of clamping force.
Compared with prior art, the invention have the advantages that
1. the location of fixture and the power source of clamping are from hydraulic cylinder, are advantageously implemented location and the automatization of clamping, and the power that simultaneously clamps on also is easily controlled;
2. it is attached by connection sheet between wedge and connecting rod, it is ensured that when wedge retreats, can pass through to connect sheet drivening rod and rotate counterclockwise, it is achieved thereby that the reset operation of clamping;
3., by square bearing pin transmission moment of torsion between connecting rod, it is ensured that the reliability of transmission, decrease part, simple in construction simultaneously.

Detailed description of the invention
The present invention realizes location and the clamping of workpiece to be machined 16 by the thrust of hydraulic cylinder and V-block 11. During work, hydraulic oil enters from the fuel feed hole of cylinder bottom 6, piston rod 7 is promoted to stretch out, piston rod 7 is connected with wedge 10 by studs 9, wedge 10 stretches out to the left under the promotion of piston rod 7, the slope driving first connecting rod 12 of wedge 10 turns clockwise, and under the effect of bearing pin 14, drives second connecting rod 13 together to turn clockwise, thus workpiece to be machined 16 is pressed on V-block 11, it is achieved that location and clamping.
After removing hydraulic coupling, under the effect of back-moving spring, piston rod 7 retreats, wedge 10 is driven to move right, owing to being attached by connection sheet 15 between wedge 10 and first connecting rod 12, in the process that wedge 10 moves right, first connecting rod 12 will be forced to rotate counterclockwise, it is achieved thereby that the automatically reseting of fixture.
The operating process of the present invention is as follows:
Clamp operation
Piston rod 7 is under the effect of hydraulic oil, to left movement, is connected by studs 9 between wedge 10 and piston rod 7, then wedge 10 also under the effect of piston rod 7 to left movement. Wedge 10 promotes first connecting rod 12 to rotate counterclockwise around bearing pin 14, under the effect of bearing pin 14, drives second connecting rod 13 to turn clockwise, then clamping workpiece 16.
Loosening operation
After removing hydraulic coupling, under the action of the spring, piston rod 7 retreats, and pulls wedge 10 to move right. Wedge 10 pulls connection sheet 15 together to move right. Then under the effect connecting sheet 15, first connecting rod 12 turns clockwise, and loosens workpiece.
