Abstract
Different car body parts needed for a complete main body are preworked at a subassembly station and then are releasably attached to corresponding jig units, each unit having a universal frame on which is mounted a set of special jigs conforming to the kind and type of car body being produced. Each jig unit is moved by an independent conveyor to a main assembly station where it is transferred to a corresponding positioning device. Each positioning device then moves its respective jig unit from a first position to a second position predetermined so as to place the different body parts in proper juxtaposed relation for welding by automatic welding devices. Upon welding, the jig units are released from all of the body parts except the under body, are retracted by their respective positioning devices, and are transferred back to their individual conveyors for return to the subassembly station. The completed car body is moved to a succeeding work station, where the under body jig unit is released and returned to the subassembly station.
