The 180 degree rotating pneumatic cylinder drives the compression plate to rotate 90 degrees through the piston rod, and then moves and compresses the workpiece. The principle of action is to process a 90 degree spiral groove on the piston rod, install a fixed guide pin on the cylinder body, and insert the spiral groove. When the piston pushes the piston rod forward, under the positioning guidance of the pin, the composite movement of movement and rotation is completed, thus completing the clamping guidance this process.
