Description

[Technical Field]

[0001] The present invention relates to the field of machining tools, and more particularly to a power-boosting air vice. [Background technology]

[0002] A vise is an auxiliary tool commonly used in the field of machining, used to clamp a workpiece. In conventional vises, the distance between the movable jaw and the fixed jaw can be adjusted by turning a screw during application, thereby clamping the workpiece. However, when the workpiece is finished being machined and needs to be replaced with a new one, the screw must be loosened, and the screw must be frequently turned manually during continuous production to remove and install the workpiece, which is inefficient and requires a lot of labor.

[0003] The feature of the power-boosting vise is that it completely eliminates the hydraulic transmission system, eliminating the problems of pressure loss due to oil leaks and the need for constant maintenance due to deterioration and wear of the oil seal, and it has fast supercharging and never loses pressure.

[0004] When a vise is in use, the movable jaw and vise base usually abut on three sides, and as the movable jaw frequently moves toward the fixed jaw, the contact surface between the end of the movable jaw closest to the fixed jaw and the vise base is damaged, causing play in the engagement between the movable jaw and the vise base.When the vise clamps a workpiece, the screw exerts force on the movable jaw, causing the movable jaw to deflect relative to the vise base, away from the side that receives the force, which interferes with the vise cover, making it difficult to clamp the workpiece and making it more likely that the workpiece will be pulled up when being processed. Summary of the Invention [Problem to be solved by the invention]

[0005] In response to the problems present in the prior art, the object of the present invention is to provide a multiplying air vise, which uses a multiplying cylinder to provide power and a screw to move the movable jaw to the fixed jaw, thereby clamping and fixing the workpiece. The multiplying cylinder is controlled by a control valve, and the screw nut moves the slider with the rotation of the screw, thereby moving the movable jaw and clamping the pipe jaw and the workpiece. This not only effectively prevents play from occurring between the movable jaw and the caliper body, but also makes the workpiece more firmly clamped, preventing it from being pulled up. [Means for solving the problem]
