Assembling method of aero-engine

Abstract

The invention discloses an assembling method of an aero-engine. The assembling method of the aero-engine includes steps as follows: step 1: a core engine is assembled; adjustable clamping and connecting devices are utilized during mounting; assembling requirements of the whole engine and engines in different outer diameters can be met simultaneously through clamping and connection of an intermediate case and an auxiliary assembling platform; step 2: a conveying assembly is assembled, a core engine combined unit is used as a base, low-voltage components such as a fan and the like are butt-jointed to high-voltage components of the core engine according to a vertical assembling scheme, and a diffuser, a thrust cylinder, a nozzle and the like are mounted according to a horizontal assembling scheme; step 3: a final assembly is assembled, an accessory gearbox, external accessories, pipelines and cables are mounted according to a horizontal assembling scheme. According to the assembling method of the aero-engine, through application of the adjustable clamping and connecting devices, adjusting operations for three spatial attitudes including vertical lifting, pitching overturning and axisrotation which are required during assembly of the aero-engine can be integrated into one organic connection whole.

Description

Technical field [0001] The invention relates to the field of aeroengines, in particular to a method for assembling aeroengines. Background technique [0002] The aero engine is a highly complex and precise assembly with large outer dimensions and weight, and a variety of procedures. During the assembly process, the engine assembly attitude is adjusted to meet the operability and carry out the transfer and external assembly between the large engine units. Complete machine assembly tasks such as pipeline installation. When designing the assembly process of the whole machine, the reasonable and pleasant design of posture adjustment, as well as the engine assembly process with different operation functions have an important influence on the scientific research production efficiency and the utilization of auxiliary resources. [0003] The existing technical solution is a separate assembly in which the core engine assembly, transfer assembly and final assembly assembly processes of the ...

AI Technical Summary

Problems solved by technology

[0004] Although the existing technical solutions can realize the assembly task of the complete aircraft engine, due to the single adjustment attitude and limited controllable operation, the connection between the assembly and installation of the large parts of the complete aircraft is poor; the process is complicated and the operability is poor; the ratio of resource requirements is guaranteed Many, such as assembly benches, operating sites and other shortcomings
