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.

Turret index system

A machine tool is illustrated having a workpiece support table on which a workpiece is moved by an automatically controlled workpiece gripper movable in the X and Y directions. Movement of the gripper in at least the X direction is controlled in reference to a base line which is set within the automatic control in response to abutment of the workpiece edge against a table supported stop, the stop being movable against a spring from a rest position through a first or base line set in position in response to abutment by the moving edge of the workpiece carried by the gripper. Movement of the stop through the first position automatically sets the base line within the automatic control.

Automatic side gauge for machine tool workpiece control and method

A turret punch machine is disclosed having upper and lower turrets each equipped to carry a plurality of tools. The turrets carry a plurality of modules projecting from a central turret section in spoke-like fashion. The modules on the upper turret are each adapted to carry one or more punching tool assemblies and the modules on the lower turret are each adapted to carry one or more die tools. The modules are attached to and rotate with the turret by interfitting connections adjacent the modules' inner peripheries, the modules being easily detachable from the turrets to allow quick tool and/or module change.

Modular turret punch press

A worktable for use in association with machine tools is illustrated which has a section including a side edge of the worktable hingedly connected to the table supporting member whereby the section is tiltable under power to automatically unload a workpiece from the table. The invention is shown in connection with a workpiece gripping and moving carriage which moves the workpiece relative to the machine tool and, after completion of machining, moves the workpiece to a position on the tip table section. Control members prevent actuation of the tip table until after the workpiece gripper has deposited the workpiece on the tip table clear of the machine tool and then withdrawn to a position fully out of contact with the workpiece.
