1. An apparatus for performing assembly operations on workpieces, comprising:
- a bed defining a support surface extending along an X-axis, and workpiece supports adapted to support a workpiece in a position spaced from the support surface with opposite first and second longitudinal edges of the workpiece extending generally parallel to the X-axis and a width of the workpiece extending generally parallel to a Y-axis orthogonal to the X-axis;
at least first and second positioners each supporting and positioning a C-frame having a pair of spaced legs adapted to support tooling for operating upon the workpiece when the workpiece is positioned between the legs, each positioner comprising a platform operable to travel along the support surface of the bed in a direction parallel to the X-axis and a carriage on which the respective C-frame is mounted and which is supported on the platform of said positioner so as to be movable relative thereto, the first positioner being arranged to carry its respective C-frame adjacent the first longitudinal edge of the workpiece such that free ends of the legs extend toward the opposite second longitudinal edge of the workpiece, the second positioner being arranged to carry its respective C-frame adjacent the second longitudinal edge of the workpiece such that free ends of the legs extend toward the first longitudinal edge of the workpiece, the carriages and positioners being configured such that the positioners can pass by each other as they travel along the bed parallel to the X-axis, and wherein the C-frame of each positioner is releasably retained on the respective carriage thereof; and
a frame changer operable to remove the C-frame from the carriage of one of the positioners, transport a replacement C-frame from a service station proximate the bed to said carriage and install the replacement C-frame into said carriage, and transport the removed C-frame to the service station such that service can be performed thereon.

Abstract
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.
