Abstract

The invention provides an intelligent assembly platform for a low-pressure turbine module, and is used for the assembly of the whole aeroengine. The platform comprises a base, a fan core machine attitude adjustment system and a low-pressure turbine module position adjustment system. The fan core machine attitude adjustment system is fixed on one end of the base, and a fan core machine is installedon the fan core machine attitude adjustment system. The low-pressure turbine module position adjustment system is fixed on the other end of the base, and a low-pressure turbine module is installed onthe low-pressure turbine module position adjustment system; and the low-pressure turbine module is connected with the fan core machine, the low-pressure turbine module has four degrees of freedom ofmovement, and the fan core machine has two degrees of freedom of movement. The intelligent assembly platform for the low-pressure turbine module can improve the assembly precision, reduce the damage to parts, improve the assembly efficiency and reduce the amount of assembly labor.

Description

Technical field [0001] The invention relates to the field of aero engine assembly, in particular to an intelligent assembly platform for a low-pressure turbine unit body. Background technique [0002] The main structure of a civil turbofan aeroengine includes a fan unit body, a core unit body and a low-pressure turbine unit body. It has the characteristics of complex structure, large size, high precision, and heavy weight. Among them, the low-pressure turbine unit body includes a low-pressure turbine shaft, a low-pressure turbine rotor, a low-pressure turbine casing, etc., and the weight is concentrated on the rear end, that is, the low-pressure turbine rotor / casing end. The installation of the low-pressure turbine unit body in the assembly process of the civil turbofan aeroengine is a deep hole assembly, which is difficult to assemble. [0003] The length of the low-pressure turbine shaft of a new civil turbofan aeroengine is 1900mm and the weight is 800kg. Its front end is splin...
