Workpiece preset jig arrangement in a welding apparatus

摘要

A workpiece preset jig arrangement for a welding apparatus. The welding apparatus has an apparatus body, a welding jig mechanism on the body and clamps on the welding jig mechanism for clamping plural component parts for constituting a workpiece so that the workpiece may be welded to another workpiece by the welding jig mechanism. The preset arrangement includes a preset arrangement body positioned adjacent the welding apparatus body, a preset jig mechanism provided on the arrangement body, and preset clamps mounted on the preset jig mechanism for clamping the plural component parts. The preset jig mechanism is moveable between a set position facing the welding jig mechanism and a preset position away from the set position and the welding jig mechanism. The set position is such that the plural component parts may be transferred from the preset jig mechanism to the welding jig mechanism simply by releasing the clamps on the preset jig mechanism and engaging the clamps on the welding jig mechanism. The present jig mechanism provides an apparatus for preassembling the plural component parts while the welding jig mechanism is engaged in welding previously preassembled component parts.
