Abstract

The invention discloses an automatic rotary welding device for a bent pipe fitting. The automatic rotary welding device comprises a supporting mechanism, pull rod assemblies and a rotary positioning mechanism, wherein the pull rod assemblies are arranged on the supporting mechanism, and the rotary positioning mechanism is arranged between the pull rod assemblies and the supporting mechanism. The rotary positioning mechanism comprises a support, a rotary assembly, a driving assembly and a pipe fitting centering assembly, wherein the support is arranged on the supporting mechanism, the rotary assembly is rotationally connected with the support, the driving assembly is arranged on the supporting mechanism and used for driving the rotary assembly to rotate, the pipe fitting centering assemblyis arranged on the rotary assembly, and the positioning center of the pipe fitting centering assembly and the center of the rotary assembly are located on the same central axis. The device is reliableto use and convenient to operate, the specific rotary positioning mechanism is designed according to the characteristics of complex space bending of an aero-engine, the pipeline can automatically rotate when the complex space bending of the aero-engine and pipelines with different diameters are welded, manual argon arc welding is located at a flat welding position, the number of times of arc starting and stopping is one, and the welding effect is effectively improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing aero-engine components, in particular to an automatic rotary welding device for curved pipe fittings. Background technique [0002] There are many external pipeline parts of the engine, and the pipeline structure is complex. Most of the pipelines are curved in space, so it is difficult to realize automatic welding. Pipes and pipe joints need to be welded by hand. The diameter of the pipeline welding structure ranges from Φ6mm to Φ72mm, and the thickness of the pipe wall is 1mm. The welds need to be welded on one side and formed on both sides. went well. Argon arc welding is used for the welding of pipe and pipe structure. Since there is no suitable welding equipment, multi-stage welding can only be used for welding. There are many welding joints, and defects are prone to appear at the start and end of the weld seam, resulting in a low welding pass rate. Contents of the invention [0003]...
