Abstract

Apparatus for positioning tooling with respect to a workpiece such as for positioning an anvil and clamping members on the inner surface of a fuselage being riveted. The apparatus comprises a tooling head, a frame for supporting the head, a carriage for moving the frame relative to the workpiece including movement of the frame along an axis. The frame is movable radially of the axis toward and away from the workpiece for macro-movement of the head. The head is also movable relative to the frame for movement of the tooling radially of the axis toward and away from the workpiece for micro-movement of the tooling for clamping to and unclamping from the workpiece as well as to clear flange portions of stringers being riveted to the workpiece. The micro-movement of the tooling head relative to the frame is provided so as to achieve decreased production cycle time as well as reduced power expenditure for reduced cost during movement from one riveting location to another so that the riveting operation may be at reduced cost.
