There are several types of front-mounted pneumatic chucks, but the principle of the general high-speed and thorough claw type is as follows: the chuck and the cylinder block are integrated into one, and the compressed air enters the one-way valve from the air distribution ring through the air inlet of the cylinder block and is injected In the inner cavity of the cylinder, pull the piston and drive the jaws to clamp the workpiece. After clamping, the reversing valve is disconnected and is in a pressure relief state. The air pressure in the cylinder is sealed by the one-way valve to maintain the pressure, and the sealing ring on the air distribution ring is loosened , Separated from the cylinder, so that the chuck can run at high speed when the machine tool is started. This kind of chuck can be used for pipe thread turning, welding and cutting equipment, and of course some are used for work turntables. Because of its large stroke, it has a wide range of applications.
