AI Technical Summary

Technical Problem

The existing support brackets used for fighter jet fuselage maintenance easily obstruct the parts to be inspected, requiring repeated disassembly and adjustment, which affects maintenance efficiency and support stability. Furthermore, the fuselage angle curvature is difficult to match, posing a safety hazard.

Method used

The system employs a staggered support mechanism and an auxiliary support mechanism, including a horizontal staggered component, a sliding guide component, an arc-shaped clamping angle, and a vertical lifting component, to achieve the forward and backward staggered movement of the load-bearing bracket and the fitting of the arc-shaped clamping angle. Friction is reduced through worm gear transmission and guide rollers to ensure that the bracket fits tightly with the machine body.

Benefits of technology

The parts to be inspected can be exposed without repeated disassembly and assembly, reducing frictional resistance, ensuring a tight fit between the bracket and the machine body, improving maintenance efficiency and safety, preventing machine body shaking, and enhancing operational reliability.
