Description

Technical Field

[0002] The installation of the guide plate and the overall flow pipe is a critical step in the engine assembly process, as their concentricity and axial positioning accuracy directly affect the engine's aerodynamic performance and operational stability. Traditional installation methods primarily rely on manual adjustment, achieving alignment of the guide plate and flow pipe through repeated hoisting, measurement, and positioning. This method suffers from the following problems:

[0003] (1) Difficulty in concentricity adjustment: Factors such as gravity deformation of the guide plate and flow tube, tooling support error and other factors cause concentricity deviation, and manual adjustment is inefficient and difficult to guarantee accuracy.

[0004] (2) Cumbersome operation: It is necessary to hoist the guide plate multiple times to match the position of the flow pipe, which is time-consuming and labor-intensive, and there are safety hazards in working at height;

[0005] (3) Lack of integrated equipment: Most existing tooling is a split structure, with concentricity detection and adjustment functions separated, making it impossible to achieve real-time monitoring and dynamic correction.
