Turret positioning cylinder

The turret positioning air cylinder comprises a cylinder body, a piston rod is installed in the cylinder body, a rear end cover is installed at one end of the cylinder body, a front end cover is installed at the other end of the cylinder body, a rear air inlet hole is formed in the position, located on the rear end cover, of the cylinder body, and a front air inlet hole is formed in the position, located on the front end cover, of the cylinder body. A first inductive switch and a second inductive switch are installed on the cylinder body, and an inductive block is installed at the end, located on the rear end cover, of the piston rod. Due to the fact that the diameter of the end, located on the rear end cover, of the piston rod is larger than that of the end, located on the front end cover, of the piston rod, under the condition that air inlet pressure is the same, force generated during retraction is larger than force generated during extension, the situation that the plug pin and the pin sleeve are clamped
