Abstract
A handling tool for reorienting a workpiece in an interior of a CNC machine has a gripper assembly connected to a turret in the interior of the CNC machine. The gripper assembly is movable between closed and open positions to grip and release the workpiece and is rotatable about a longitudinal axis to reorient the workpiece in the interior of the CNC machine.
Claims17
A handling tool for reorienting a workpiece in an interior of a CNC machine comprising:
- a gripper assembly connected to a turret in the interior of the CNC machine, the gripper assembly movable between closed and open positions to grip and release the workpiece and rotatable about a longitudinal axis to reorient the workpiece in the interior of the CNC machine;
- and
- a handling tool drive shaft connected to a turret drive member, the handling tool drive shaft operable to rotate the gripper assembly about its longitudinal axis upon rotation of the handling tool drive shaft in a first direction and to move the gripper assembly between open and closed positions upon rotation of the handling tool drive shaft in a second direction.
A machine tool comprising:
- a machine cabinet defining a machine interior;
- a tool turret positioned in the machine interior;
- a rotatable workpiece spindle positioned in the machine interior;
- a gripper assembly rotatably mounted to the tool turret, the gripper assembly movable between closed and open positions to grip and release the workpiece and rotatable to reorient the workpiece in the interior of the machine tool;
- a handling tool shaft connected to and rotatably driven by a turret spindle drive motor, the gripper assembly movable between the open and closed positions and rotatable about a longitudinal axis upon rotation of the handling tool shaft;
- first and second drive gears rotatable with the handling tool shaft;
- first and second follower gears rotatably engaged by the first and second drive gears respectively;
- and
- a linear actuator in contact with a sloped face of the second follower gear.
