  • Rotary turret head apparatus
    Publication number: 20020083567
    Abstract: A rotary turret head apparatus for installing a fastener such as a rivet. The rotary turret head apparatus has a plurality of machining and fastener installation tools disposed perpendicular to the axis of rotation of the turret. The individual tools are independently powered and the entire turret head apparatus is fed toward the workpiece by a single actuator mechanism such as a roller screw or hydraulic cylinder thereby eliminating the need for a separate actuating mechanism for each tool and eliminating the need for engagement of each tool with a central actuating mechanism.
