Abstract

The invention discloses a quality control method for laser shot peening shape correction for aero-engine brackets. ; Refinement structure welding and laser shot peening shape correction; bracket assembly welding and laser shot peening shape correction; shape correction effect detection. This scheme refines the complex aero-engine bracket into three simple thinning structures, and adopts the processing sequence of segmental welding, segmental laser shot peening, final assembly welding, and final assembly laser shot peening. The laser shot peening shape correction of the structure before the final assembly welding can reduce the welding deformation of the overall structure of the bracket, so that the overall structure of the bracket is easier to correct in the laser shot peening shape correction. The invention solves the problem of deformation of the aero-engine bracket during the welding process, can accurately control the size accuracy and shape accuracy of the bracket, and has good correction effect.

Description

technical field [0001] The invention relates to the field of aviation component manufacturing, in particular to a laser shot peening quality control method for aircraft engine brackets. Background technique [0002] The aircraft engine support is a space frame structure obtained by welding hollow steel pipes. During the welding process of the support nodes, the base metal is locally heated unevenly, which is prone to welding residual stress, causing large residual deformation of the space frame structure, and the shape accuracy is low. Poor, causing the mounting bolts of the engine bracket to deviate from the installation position, which affects the subsequent assembly. At present, the method used in practical engineering applications is to increase the size, and then use machining to cut off the excess deformation. This method is time-consuming and labor-intensive, and the processing consistency is poor. [0003] At present, the existing shape correction method is to repea...
