摘要：A method and system for automatically attaching a sub-assembly such as astrut to a main assembly such as a vehicle body frame in a production line. The methodinvolves the steps of moving the sub-assembly including a separable engagement meansto a predetermined location of the main assembly, anchoring the engagement means ofthe sub-assembly to a positioning part located at the predetermined location of the mainassembly so as to temporarily attach the sub-assembly to the main assembly, moving anautomatic fastening tool to the opposite side of the predetermined location of the mainassembly to which the sub-assembly is attached and tightening fasteners in theautomatic fastening tool onto the sub-assembly so as to permanently attach the sub-assembly to the predetermined location of the main assembly. The engagement meanscan then be removed. Since the sub-assembly is temporarily attached to the

predetermined location of the main assembly, the tightening operation of a fastener issimplified and can be carried out at a different working station, in addition to variousother advantages.
