An automated assembly machine for fabricating large mechanical structures including a floor assembly jig for receiving and holding parts in a desired orientation, a pair of carriages, a first drive mechanism for independently driving the carriages longitudinally, a second drive mechanism for moving the carriages vertically, a tool tray mounted on the carriages, and a plurality of tools, including a drill, a hole diameter measurement probe, a nut runner, and an electromagnetic riveter, mounted on the tool tray for lateral movement toward and away from a workpiece clamp-up position. The tools are positioned at the workpiece clamp-up position by moving one of the carriages longitudinally along the floor assembly jig and raising the other carriage to elevate the tool tray to a desired elevation. |

DETAILED DESCRIPTION We claim: 1.
An automated assembly machine for fabricating large mechanical structures from a multiplicity of individual parts, comprising: a floor assembly jig having a multiplicity of clamps for receiving and holding said parts in a desired orientation with respect to each other and in a desired position in space, clamped together in a workpiece clamp-up position, having supports and guides for supporting and guiding a pair of carriages along the length of said machine on opposite sides of said workpiece clamp-up position; a pair of carriages supported and guided on supports and guides on said floor assembly jig, said carriages being disposed on opposite sides of said workpiece clamp-up position; a first drive mechanism for independently driving said carriages longitudinally along said guides and supports; a second drive mechanism for moving said carriages vertically with respect to said floor assembly jig; a tool tray mounted on at least one of said carriages, said tool tray being mounted on a shifting mechanism for longitudinal movement on said at least one carriage relative to said floor assembly jig; a plurality of tools, including a drill, a hole diameter measurement probe, a nut runner, and an electromagnetic riveter, mounted on slides on said tool tray for lateral movement toward and away from said workpiece clamp-up position; a motive device for moving each of said tools toward and away from said workpiece clamp-up position; whereby said tools can be positioned at any desired position on said workpiece clamp-up position by moving said at least one carriage longitudinally along said floor assembly jig to a desired longitudinal position, and raising said at least one carriage to elevate said tool tray to a desired elevation, shifting said tool longitudinally along said at least one carriage to align one of said tools with the desired position, and sliding the one of said tools laterally into said workpiece clamp-up position.
2.
An automated assembly machine as defined in claim 1, further comprising: a nose on a side of said tool tray adjacent said workpiece clamp-up position, and a translating mechanism for moving said nose into said workpiece clamp-up position to engage a workpiece supported therein to clamp said workpiece while said tools perform their functions
