The invention relates to a tool for applying punched rivets, either full rivets or semi-tubular rivets. The tool having a blank holder for pretensioning assembly pieces, especially metal sheets; a rivet punch movable in an axial direction within a cylinder of the blank holder; and a die that is arranged opposite the blank holder and punch and provided with an annular prominence on an end face thereof and facing the rivet punch. A radial outside section of said end face concentrically surrounds said annular prominence, the outside section of said end face being displaceable relative to the annular prominence as a function of one of the penetration depth of the rivet into the assembly pieces and the force that the rivet punch exerts on the rivet.

Apparatus and method for positioning tooling for operation on a curved workpiece wherein a gantry beam assembly having a movable head assembly thereon carrying tooling is pivotally connected on a pivot axis to a pair of spaced apart pedestals each having a longitudinal axis disposed substantially perpendicular to the pivot axis and wherein the workpiece is supported on a fixture between the pedestals and so that the gantry beam assembly extends along the workpiece. The pivot axis of the gantry beam assembly is moved along the longitudinal axes of the pedestals, the pivot axis of the gantry beam assembly is moved along a path substantially perpendicular to the longitudinal axes of the pedestals and the head assembly is moved along the gantry beam assembly. The foregoing operations move the head assembly relative to the workpiece enabling the tooling to perform operations thereon. The gantry beam assembly is pivoted about the pivot axis and the head assembly is pivoted about an axis substantially perpendicular to the pivot axis for normalization of the head assembly relative to the workpiece. The gantry beam assembly can be tilted along a plane substantially parallel to the longitudinal axes of the pedestals to accommodate frustoconical and similar shaped workpieces. The gantry beam assembly can be provided with gimbal connections to the pedestals to provide additional degrees of freedom for operation on workpieces having compound curvatures.

The present invention relates to a tool position detection assembly that aligns a tool relative to a feature within a lap joint of a first panel and a second panel. The detection assembly includes an indexing device engageable to the feature. The indexing device includes a reflecting member having a width. The assembly also includes an end-effector movable along at least one axis parallel to the lap joint for positioning the tool. The end-effector has a dual laser device for detecting when the device is aligned with the reflecting member.

An assembly apparatus for aircraft wing panels and the like includes one or more positioners movable along a bed above which the panel is supported, each positioner carrying a tool-supporting frame on which assembly tools are mounted for performing assembly operations on the panel. The tool-supporting frame is releasable from the positioner, and the apparatus includes a frame changer that travels to the positioner, removes the tool-supporting frame, installs a replacement frame into the positioner, and carries the removed frame to a remote service station where servicing operations are performed on the frame.

A rivet coupling device 1 has a connector holder unit 250 which carries connectors 200 and a board 50. A supporting die 150 is disposed beneath the connectors 200, and an upper tool unit 92 is disposed above the connectors 200. The upper tool unit 92 can be lowered in order to couple rivets 220. In conjunction with this movement, a link mechanism 30 is actuated to move a cam plate 80, whereby the supporting die 150 is raised slightly by cam projections 148, so that the rivets 220 extending through the connector 200 are deformed between crimpers 134 on the upper tool unit 92 and the supporting die 150. Prior to rivet coupling, a slight gap is formed by the spring terminals between the board 50 and the connector 200. After rivet coupling is performed, this gap is eliminated without deforming the board 50.
