Abstract
The utility model relates to a force-strenthening mechanism for a pneumatic fixture, which comprises a cylinder, a piston rod, first hinge rods, rollers, second hinge rods, slide rods, force output pieces and return springs, wherein one end of each slide rod is connected with the corresponding force output piece through a wedge; the force output pieces are provided with the return springs; the cylinder is provided with the piston rod; the piston rod is hinged with the first hinge rods; one end of each roller is connected with the corresponding first hinge rod, and the other end of each roller is connected with the corresponding second hinge rod; and the second hinge rods are hinged with the other ends of the slide rods. The structure of the product is simple and compact, the force strenthening factor is large, and meanwhile, the double sides of a work piece can be symmetrically clamped by the pneumatic fixture through utilizing single input force, so the problems that as the system pressure in the pneumatic fixture cannot be over high, the clamping force of the fixture is limited, and the like are solved.
Description
Technical field: the utility model relates to a kind of air-actuated jaw force-increasing mechanism.
Background technology: the working media of air-actuated jaw is the compressed air of cleaning, its advantage is can not be easy to generate pollution as hydraulically operated fixture, the piston movement speed of air-actuated jaw is significantly higher than hydraulically operated fixture simultaneously, therefore production efficiency is higher, but in air-actuated jaw,, thereby cause the system pressure P can not be too high because gas very easily leaks, general P=0.4～0.7MPa, so the chucking power of air-actuated jaw is restricted.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of air-actuated jaw force-increasing mechanism is provided, and it has mainly solved in air-actuated jaw because system pressure can not be too high, and the chucking power of anchor clamps such as is restricted at problem.The purpose of this utility model is achieved in that the air-actuated jaw force-increasing mechanism is made of: cylinder, piston rod, first toggle, roller, second toggle, slide bar, power output, back-moving spring.Slide bar one end of two symmetries is connected with the power output by wedge, on the power output back-moving spring is housed, piston rod is housed on the cylinder, the piston rod and first toggle are hinged, roller one end is connected with first toggle, the other end is connected with second, and the other end of second toggle and slide bar is hinged.This product structure is simply compact, and the reinforcement coefficient is big, can utilize single input power simultaneously, realizes that air-actuated jaw carries out the process that the bilateral symmetry clamps to workpiece, has solved in the air-actuated jaw because system pressure can not be too high, and the chucking power of anchor clamps such as is restricted at problem.
