Abstract

The invention discloses a butt welding device for draught fan half shells. According to the butt welding device for draught fan half shells, the structure is simple, a machine enclosure to be welded can be positioned effectively, the fluency in the welding process is good, the stability is high, and the wielding quality can be guaranteed. The welding device comprises a welding machine rotating part, a welding machine lifting part, a rotating motor and a welding gun component. The welding machine rotating part comprises a welding bottom frame, a level 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 positing welding table. The rotating motor is connected with a reducer. An output shaft of the reducer is connected with an output gear. The output gear is meshed with the welding table gear. The welding machine lifting part comprises stand pillars and a vertically-adjusting lead screw component. A horizontally-adjusting lead screw component is arranged on the main welding part. The butt welding device for draught fan half shells has the advantages that the welding gun can be aligned with a portion to be welded accurately, positioning is firmly, the welding process is continuous, a welding gun component does not move when welding is conducted, changing of welding position is realized through the rotation of the machine enclosure to be welded, the stability is good, and the welding quality is high.

Description

technical field [0001] The invention belongs to the technical field of welding devices, in particular to a fan half-shell butt 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 stabili...
