Abstract

The invention provides an aero-engine double-right-angle support assembly welding positioning device and method. The technical problems that an existing aero-engine double-right-angle support assembly deforms in welding and is low in efficiency are solved. According to the welding positioning device, a simple and effective clamping mode is adopted, sheet metal parts are transversely positioned and longitudinally clamped, tubular positions of all parts are axially clamped, part positioning points are increased, through one-time clamping, it is guaranteed that the coaxiality reference of the parts is not changed, part welding deformation is improved, automatic transfer welding of thin-wall parts is achieved, and multi-shape parts are clamped, positioned and welded at a time; the working efficiency is greatly improved, the form and location tolerance requirement is met, the problem of welding deformation of thin-walled pipes containing double right-angle sheet metal parts is effectively solved, and the working reliability of the engine boundary layer header pipe left support and the engine boundary layer header pipe right support is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and in particular relates to a welding positioning device and method for a double right-angle support assembly of an aero-engine, and is particularly suitable for clamping and centering when welding multi-shaped thin-walled tubular parts. Background technique [0002] Stainless steel is widely used in the aviation field due to its good material properties; thin-walled parts are widely used in the aviation field due to their light weight, material saving, and compact structure. [0003] In order to ensure the welding strength, stainless steel thin-walled parts are often welded by argon arc welding. However, when this method is used for direct welding, the deformation is large, which affects the subsequent assembly and use, and may easily cause aeroengine failure. At present, although the deformation can be reduced by post-welding shape correction, this method will cause damage to th...
