Cabin assembling and welding tool for casting lap joint thin-wall skin structure

Abstract

The invention provides a cabin assembling and welding tool for a casting lap joint thin-wall skin structure. The cabin assembling and welding tool comprises a supporting frame, a fixed blocking disc assembly, a movable blocking disc assembly, a front base, a rear base, pull rods and a holding ring assembly. The supporting frame is located at the bottom of the assembling and welding tool and bearsall tool components on the supporting frame. The fixed blocking disc assembly and the movable blocking disc assembly are installed at the front end and the rear end of the supporting frame respectively and limit the space positions of a front end frame and a rear end frame. The upper molded surfaces of the front base and the rear base and the inner molded surface of the holding ring assembly forma complete cabin outer molded surface which surrounds the skin of a cabin and the outer molded surface of a casting. The pull rods enable the matching end faces of all assemblies of the cabin to be tightly attached. The cabin assembling and welding tool can achieve accurate assembling of the cabin of the casting lap joint thin-wall skin structure before welding, deformation of an assembling body in the whole welding process is effectively controlled, the design requirement of the cabin is met, a machining procedure after welding does not need to be supplemented any more, the manufacturing costis reduced, and the production period is shortened.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a welding tool for a cabin with overlapping thin-walled skin structures of castings. Background technique [0002] Due to the needs of the industry, the processing and manufacturing of cabin products is a key research and development project. Such as figure 1 As shown, the frame of this type of product is mainly composed of cabin castings, end frames on both sides and thin-walled skins, assembled and welded, and a storage space is formed between the castings and the upper thin-walled skins. The overall welding of the cabin has both longitudinal welds and circumferential welds. The welds are long and irregular. The welding sequence, weld distribution and stiffness of each part will directly affect the welding quality. At present, in the manufacture of cabin products, the cabin castings and end frames are assembled and welded into components, and then the thin-walled...
