ABSTRACT:
A workpiece inversion system for orienting a workpiece in a conventional milling machine or the like. The workpiece is securely attached to a pallet. The pallet is of uniform design to provide a standard interface for presenting the workpiece to the milling machine. The pallets are transported to the milling machine where a combination of parts senses the pallet orientation. Upon arrival to the input station the pallet mates with an inverting receptor adjacent the input station. An actuator rotates the pallet 180 degrees thereby inverting the pallet and the attached workpiece. The inverted pallet is moved onto an inverted linear actuator disposed within the volume above the milling head. The inverting receptor returns to it original position to receive another workpiece. The inverted workpiece is moved through the machining area. As machining occurs, debris dislodged by the force of forced oil lubrication and gravity will fall away from the workpiece. The pallet then passes thorough the machining area and is mated with a reverting receptor. The reverting receptor then rotates the pallet containing the workpiece 180 degrees. The pallet and workpiece are placed back in the same relative position they had when first entering the input station on the other side of the machine.
