Plate gas-liquid reinforcement clamp

Abstract

The invention relates to the machining clamp field, in particular to a plate gas-liquid reinforcement clamp. The plate gas-liquid reinforcement clamp comprises a clamping jaw rod, a bar-shaped clamping jaw seat, a reinforcement hydraulic cylinder and a power cylinder, wherein the clamping jaw seat is sleeved with the middle of the clamping jaw rod and a spring, the spring is supported below the clamping jaw rod, one end of the clamping jaw rod is arranged to be a clamp jaw, the other end of the clamping jaw rod is connected with a power rod of the reinforcement hydraulic cylinder, the power cylinder is divided into a hydraulic transmission cylinder and an air pressure power cylinder, the reinforcement hydraulic cylinder is communicated with the hydraulic transmission cylinder through a hydraulic pipe, the hydraulic transmission cylinder and the air pressure power cylinder adopt a T-shaped body, and the inner diameter of the hydraulic transmission cylinder is one tenth of that of the air pressure power cylinder; a dumbbell-shaped power piston is arranged in the cylinder body, and an adjusting valve is arranged in the hydraulic transmission cylinder. The plate gas-liquid reinforcement clamp has the advantages that the pressurization effect is realized by the aid of the linkage of hydraulic pressure and air pressure, the use of a pressurization mechanical structure is reduced, the clamp structure is simple, and stable clamping force can be provided.

Description

technical field [0001] The invention belongs to the field of clamps for mechanical processing, in particular to a clamp with gas-hydraulic force boosting for a plate. Background technique [0002] At present, the existing clamps include a fixed clip body, a movable clip body, a guide rod, and a booster handle. The guide rod is equipped with a locking clip and a booster clip. The guide rod on the fixed clamp body moves to change the distance between the fixed clamp body and the movable clamp body to realize the clamping of the object. However, the object can only be clamped to a certain extent by the force handle. If further clamping is required, the user can do nothing. Especially when grinding the plate, there is a large gap between the grinding tool and the plate. The interaction force requires a large clamping force to realize the clamping of the plate, and the adjustment of the clamping force cannot be realized by using conventional clamps due to the different materials...

However, the object can only be clamped to a certain extent by the force handle. If further clamping is required, the user can do nothing. Especially when grinding the plate, there is a large gap between the grinding tool and the plate. The interaction force requires a large clamping force to achieve the clamping of the plate, and the clamping force cannot be adjusted by using conventional clamps due to the different materials of the plate.
