Problems solved by technology

[0002] When the aero-engine is assembled, it is necessary to check the gap between the rotor and the stator of the axial flow compressor. Usually, the rotor and the stator of the axial flow compressor are installed on the engine for inspection. When the rotor and the stator are found to be When the clearance of the stator does not meet the technical requirements, the rotor and stator of the axial flow compressor need to be removed for disassembly and troubleshooting, which affects the assembly cycle of the engine
[0003] Especially for an axial-flow compressor, the split stator casing is positioned at the inner seam and has an interference fit, so it cannot be directly installed on an aero-engine

Abstract

The invention relates to an axial-flow compressor unit body component assembling device and method. According to the technical scheme, the axial-flow compressor unit body component assembling device comprises a base and a centering mechanism, wherein the base comprises a disc, supporting legs, a first positioning semiring, a second positioning semiring and a positioning sleeve, the supporting legs are arranged below the disc, and the first positioning semiring, the second positioning semiring and the positioning sleeve are arranged on the disc; the centering mechanism comprises a hollow shaft and a positioning cover, the hollow shaft is arranged in the center of the positioning cover, and the outer edge of the positioning cover is provided with a positioning edge. According to the technical scheme, conformity between axial clearance and radial clearance between a rotor and a stator of an axial-flow compressor and technical requirements can be check in advance, the axial-flow compressor is installed on an aircraft engine in the mode of an axial-flow compressor unit body component, the number of times for repeated assembly is reduced, and the assembly period of the aircraft engine is shortened.

Description

technical field [0001] The invention relates to an assembling device and an assembling method, in particular to an assembling device and an assembling method of an axial-flow compressor unit body assembly. Background technique [0002] When the aero-engine is assembled, it is necessary to check the gap between the rotor and the stator of the axial flow compressor. Usually, the rotor and the stator of the axial flow compressor are installed on the engine for inspection. When the rotor and the stator are found to be When the clearance of the stator does not meet the technical requirements, the rotor and the stator of the axial flow compressor need to be removed for disassembly and troubleshooting, which affects the assembly cycle of the engine. [0003] Especially for an axial-flow compressor, the split stator casing is positioned at the inner seam and has an interference fit, so it cannot be directly installed on an aero-engine. Contents of the invention [0004] The inven...
