Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of assembly tooling, in particular to an aero-engine assembly tooling. BACKGROUND

[0002] In the field of aero-engine manufacturing, the assembly process is a key link to determine the performance and reliability of the engine, which has very high requirements for the stability, adaptability and operation flexibility of the tooling equipment.

[0003] However, the current tooling is mostly fixed structure, which can only realize single-angle or single-height assembly operation. The size of aero-engine parts varies greatly, and multiple postures such as horizontal and inclined need to be switched during assembly to adapt to different station requirements. Fixed tooling needs to rely on manual assistance to turn over or move, which not only increases labor intensity, but also cannot adapt to the operation habits of assembly personnel of different heights, and long-term bending or standing on tiptoe operation is easy to cause fatigue, which indirectly reduces assembly efficiency and quality stability.

[0004] The clamping point position and clamping range of the existing clamping tooling are mostly preset fixed values. For different types and structures of aero-engines (such as turbofan engines and turboprop engines), special clamping modules need to be replaced, which wastes time and has low replacement efficiency.

[0005] The core components of aero-engines (such as rotor assemblies and combustion chambers) are heavy, and the placement and preliminary positioning before assembly rely on lifting equipment and manual calibration, which is complicated and has low positioning accuracy. At the same time, the bottom supporting structure of the traditional tooling is mostly fixed support. When the engine is turned to a horizontal assembly posture, the bottom supporting part is easy to block the end interface (such as the fuel interface and the electrical interface), and the bottom supporting structure needs to be removed before the assembly can continue, which causes process interruption and prolongs the assembly cycle.

[0006] The engine assembly needs to be operated at different positions in the circumferential direction, such as bolt fastening and pipeline connection. The existing tooling mostly needs manual pushing to rotate the engine, which is labor-intensive and has high labor intensity. SUMMARY
