ABSTRACT:
A compressed air valve circuit actuated assembly for operating a rotary tool turret of a lathe is disclosed which includes an actuator movably disposed in a housing and fixedly connected through an opening to the turret. The actuator moves linearly between a recessed position, wherein a first actuator attached ring of spaced apart teeth is closely intermeshed with a second housing attached ring of identical teeth, and an advanced position wherein the rings are decoupled to permit turret and actuator rotation. A series of compressed coil springs confined between the actuator and housing biases the actuator toward the recessed position. Compressed air supplied from the circuit to a housing chamber moves the actuator to the advanced position in opposition to the springs. A cross-piston, disposed in a bore formed in a housing surface portion and movable between start and ending positions, is coupled by an indexing pin to a slot in the actuator only when the actuator is in the advanced position. The circuit actuates the cross-piston to move and, simultaneously, cause the pin to rotate the actuator through a predetermined angle while the actuator is advanced, whereafter, the circuit switches to permit the springs to return the actuator to the recessed position to decouple the pin from the slot. The circuit then return operates to return the cross-piston to the start position to complete an assembly operating cycle.
