ABSTRACT:
A turret indexing system for a turret punching machine having a plurality of equally spaced tool punching stations carried on the turrets which may be rotatably positioned to place selected punching tools in register with a punching ram. Turret indexing is accomplished with a pneumatic cylinder driven reciprocating drive arrangement utilizing a pneumatically actuated clutch to drive the turrets through a one direction, incremental indexing rotation which is equivalent to one tool punching station spacing. A shot pin arrangement is effective to lock the turrets in an operating position and provide small corrective repositioning of the turrets, when required, to precisely position the turrets relative to the punching ram. A control system provides an automatic sequenced cycling of the indexing system to position each required punching tool in an accurate punching position.
