Design and Key Process of Integration System of Engine Assembly and Inspection

The integration system of engine assembly and inspection is introduced. A new technology of aerostatic bearing, which is the core part of the system, is developed. By using a large-scale optical processing machine tool, an optical aerostatic working surface is obtained, and a high-precision aerostatic rotary table is manufactured. On this basis, the integration system of engine assembly and inspection with high precision, high reliability, high usability and high customizable characteristics is developed, which breaks through the bottleneck of domestic aeroengine assembly process and equipment manufacturing technique. According to the assembly experiment of the compressor rotor, the accumulative radial runout error of the multi-stage assembly body is reduced by 46%, and the accumulative coaxiality error is reduced by 30%, which verifies the effectiveness of the assembly system and the assembly process.
