Automated spar assemby tool

摘要

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.
