The invention belongs to the technical field of
aviation accessory production, and particularly relates to a
welding machining system and method for assembling a combined
aviation aluminum shell. The inner supporting plate bending
assembly and the inner supporting plate punch forming
assembly are jointly used for conducting
punching machining on the upper side and the lower side of the joint, a protruding plate which is folded inwards is formed in the
punching forming process, and the inner supporting plate bending
assembly is used for bending the protruding plate to form an inner supporting plate; the inner side and the outer side of the joint can be welded at the same time through the joint
welding assembly; by means of the inner supporting plate
punching assembly, an installation hole facilitating installation of a threading plate through a bolt can be formed and machined in the inner supporting plate, in this way, main components of the combined type
aviation aluminum shell can be reliably clamped, and reliable anti-deformation supporting is provided in the
trepanning and
welding process; two sides of the weld are uniformly heated, and
internal stress is relatively balanced, so that deformation is reduced, and the overall quality of the weld is improved.
