ABSTRACT:
A car body side aperture assembly system for welding together multiple component parts of side apertures for different vehicle bodies at successive framing and respot welding stations. Overhead conveyor carriers each with laterally spaced racks for supporting loosely mounted component parts for left and right side apertures move into station position over selectively positioned framing station fixtures for accurately locating the component parts in required relation. Programmable robot welders produce different pretack welds at successive framing stations as well as respot welds at intermediate stations as required for different side apertures. The system includes means for selectively shuttling framing station pallets each with outwardly expandable fixtures having tooling for locating the multiple component parts of a particular side aperture at each framing station. Side aperture components exposed outwardly of both carrier and locating fixture provide optimum flexibility and accessability for robot welders located on either side of the framing station.
