Description

Pneumatic vise

Technical field

The present invention relates to the technical field of vise, specifically a pneumatic vise.

Background technique

Pneumatic vise, also known as: pneumatic flat-nose vise, pneumatic vise, pneumatic bench vise, etc., is a fast fixture suitable for mass production and processing such as biaxial compound machines, CNC machining centers, milling machines, drilling machines, etc. Existing technology In the process, the pneumatic vise is used to quickly fix the workpiece, but when the workpiece needs to be rotated to adjust the processing surface, the pneumatic vise needs to be loosened to adjust the workpiece, and then the pneumatic vise is used to clamp the workpiece. The operation is more cumbersome. This will affect the processing efficiency of the workpiece.

For example, the patent publication number CN215093036U is a new type of pneumatic vise. This new type of pneumatic vise solves the problem of a small clamping range of traditional pneumatic vise. It also has both force-increasing and self-locking functions, improving the convenience of use. There is a problem that when the workpiece needs to be rotated to adjust the processing surface, the pneumatic vise needs to be loosened to adjust the workpiece, and then the pneumatic vise is used to clamp the workpiece. The operation is relatively cumbersome, which will affect the processing efficiency of the workpiece.

For example, the patent publication number CN115853852A is specifically a Power pneumatic vise, which belongs to the field of mechanical processing tools. It uses multiple cylinders to ventilate in series, pull the piston backward, and use the connecting block to drive the screw rod, so that the movable jaws are driven by the screw rod. Clamping allows the workpiece to be quickly and automatically clamped during machining. It uses standard pneumatic control components, which not only has low energy consumption, but also uses a clever combination of control valves and pneumatic circuits. Single or multiple cylinders work in series to achieve convenient control and It has the functional requirements of reducing costs, having a wide range of adjustable clamping force, and meeting the clamping needs of most products. When the workpiece needs to be rotated to adjust the processing surface, the pneumatic vise needs to be loosened to adjust the workpiece, and then reused. The operation of pneumatic vise to clamp the workpiece is relatively cumbersome, which will affect the processing efficiency of the workpiece.
