Abstract

The invention discloses a machine shell welding device, and aims at providing the device which is reasonable in structure, can effectively position a to-be-welded machine shell, is high in smoothness and stability in the welding process, and can ensure the welding quality. The machine shell welding device comprises a welding machine rotating part, a welding machine lifting part, a rotating motor and a welding gun assembly. The welding machine rotating part comprises a welding bottom frame, a horizontal positioning welding table and a welding table gear. The welding table gear is connected with a main rotating shaft. A positioning fixture is arranged on the positioning welding table. The rotating motor is connected with a speed reducer. An output shaft of the speed reducer is connected with an output gear which is meshed with the welding table gear. The welding machine lifting part comprises a stand column and a vertical adjusting lead screw assembly. A transverse adjusting lead screw assembly is arranged on the main welding part. The machine shell welding device has the advantages that a welding gun and a to-be-welded part can be accurately aligned, positioning is firm, the welding process is ceaseless, the welding gun assembly is still during welding, the welding position is changed through the rotation of the to-be-welded machine shell, stability is high, and the welding quality is high.

Description

technical field [0001] The invention belongs to the technical field of welding devices, in particular to a casing welding device. Background technique [0002] Industrial fans, especially medium and large fans, are mostly supported by metal casings. Castings can be used for low-cost ones, and sheet metal parts and forgings can be used for high-quality ones. None of them will be integrally formed, and the separate shells need to be connected together by welding to form a complete fan casing, while a large number of fan casings adopt two symmetrical (or similarly symmetrical) half-shell butt welding In the form of welding, the welding position is the circumferential butt joint edge of the two half shells. However, at present, when the casings of medium and large industrial fans are butt welded, due to their large size and inconvenient operation, there are still some problems in the uniformity and continuity of the weld seam, as well as the convenience and stability of the wel...
