Owing to there is such problem, so be necessary to improve.
Summary of the invention
Problem to be solved in the utility model is: solve the problem that existing clamp power is inadequate.
The scheme that the utility model adopts is:
A kind of novel mechanical clamp for machining, comprise pedestal and jig arm, it is characterized in that: said jig arm comprises interior jig arm and outer jig arm, interior jig arm and outer jig arm quantity are all upper and lower two, and outer jig arm is positioned at outside jig arm; Be provided with hollow section in said pedestal, hollow section inside is provided with drive block, and drive block comprises two former and later two trapezoidal portions; Be provided with hydraulic jack in pedestal side, the piston rod of hydraulic jack is connected with said drive block; Pedestal is provided with two groups, front and back push rod, and two groups, front and back push rod can be up and down on pedestal, and the inclined-plane, outer end and the interior jig arm afterbody that match with one of them trapezoidal portion in front push rod the inner offset; Rear push rod the inner be portion trapezoidal with another match inclined-plane, offset with outer jig arm afterbody after the bifurcated of outer end, the neutral gear that said interior jig arm is formed after being positioned at rear push rod bifurcated; Be provided with upper and lower two gripper arm seats be obliquely installed in pedestal front end, said interior jig arm and outer jig arm all with gripper arm seat chain connection; Return spring is provided with between interior jig arm and pedestal.
During use, operation hydraulic jack, make piston rod layback left, drive block to left movement, trapezoidal portion, respectively with front push rod, rear push rod below inclined-plane contact, continue in the process run left at drive block, front push rod, rear push rod are ejected, interior jig arm and outer jig arm afterbody are by jack-up, and like this, jig arm and outer jig arm front end just can by Workpiece clampings, to process; After processing, operation hydraulic jack inverted running, drive block moves right, unclamp between drive block and front push rod, rear push rod, front push rod, rear push rod inside contract, and interior jig arm is rebounded rapidly and interior jig arm is unclamped under the effect of return spring, and interior jig arm external jig arm in the process of unclamping is clashed into, thus drive return, such workpiece just can take off.
The beneficial effect that the utility model produces is: have inside and outside two groups of jig arm, and often group jig arm is all upper and lower two groups, two groups of jig arm drive forward and backward push rod outwards to uphold by drive block, make jig arm action realize clamping, the interlock between each parts is effective, and clamping force is strong, return spring can order about jig arm and open shape, make workpiece convenient disassembly, thus can increase work efficiency, guarantee crudy.
