Abstract:
A mechanism for rotary indexing a turret on a machine tool and including a rack (39) engaging a pinion operatively connected to the turret, the rack being formed on a piston (41) slidably mounted in a cylinder (42), the cylinder having means for the supply and exhaust of fluid under pressure, movement of the piston between mid-position and one end affecting single turret indexing and movement from one end to the other affecting double indexing. The ends of the cylinder contain respective further pistons (48) which regulate the stroke of the main piston (41). |
