Abstract
A movable frame is supported by a counter balancing winch or a robot and carries a horizontally movable shuttle on which is mounted a motor driven drill spindle and a parallel spaced anvil both movable in a vertical direction by corresponding fluid cylinders. A clamping bushing is supported by the frame for receiving a drill bit carried by the drill spindle and then receiving a rivet carried by spring fingers on the anvil. A J-shaped or C-shaped slide member is supported by the frame for vertical movement and carries a ram which opposes the anvil when in the clamping bushing. A hydraulic cylinder is mounted on the frame and has a downwardly projecting piston rod connected to the slide member, and a clamping tool is supported adjacent the ram by a fluid cylinder within the slide member. After two or more parts are clamped between the clamping bushing and tool, a hole is drilled within the parts, a rivet is inserted into the hole by the anvil, and then the rivet is upset further by movement of the ram with the slide member. The ram and clamping tool are supported by the slide member below a reference plane define by the parts, and the other components are located above the reference plane.
