The invention discloses a quality control method for a multi-cavity complex casing, comprising the steps of: designing the process requirements for a multi-cavity complex casing based on design criteria, including benchmark system requirements, corner transition requirements, foreign matter control requirements, welding requirements, etc. ;Adopt multi-plan non-destructive inspection methods to inspect multi-cavity complex casings, reject unqualified parts, and find problems and reasons for items that do not meet the requirements of the eligibility criteria among the unqualified parts excluded in the non-destructive inspection, To provide a basis for testing the manufacturing quality and design improvement of the casing, improve the design and process requirements; carry out comprehensive test verification on the multi-cavity complex casing lubricating oil, air flow path, and casing structural strength after non-destructive inspection and feedback unqualified problems and reasons. The invention effectively eliminates various quality problems in the manufacturing process of complex casings and forms a quality control closed loop, thereby facilitating all-round control and optimization of the quality of multi-cavity complex casings and ensuring the quality requirements of complex cavity casings.
Description
technical field [0001] The invention relates to the field of manufacturing equipment, in particular to a quality control method for a multi-cavity complex casing. Background technique [0002] At present, the main function of the turboshaft engine air intake and dust prevention device is to intake air and prevent foreign objects from entering the engine, so that the engine can work stably with a long life. When used in the field, the airflow channel of the air intake dust-proof device is easy to freeze, which changes the blade-shaped flow channel and affects the dust-proof performance. The dust-proof device is integrated with the lubricating oil tank and the heat dissipation system, thereby making its internal structure very complicated. The air intake dustproof device is mainly composed of a casting casing and a sheet metal welding casing. Due to the many functions, each case has a complex internal space structure and a nearly closed cavity, hollow blades and slender pipe...
