AI Technical Summary

Technical Problem

Traditional methods for eliminating stress during milling of aircraft fuselage structural components are inefficient and resource-intensive, and are particularly ineffective for materials such as titanium alloys.

Method used

The stress relief device, which adopts a design that combines elastic support and vibration, achieves controllable vibration transmission through a combination of springs and eccentric wheels. Combined with a high-frequency vibration source driven by a motor, it uses limit blocks to constrain the vibration amplitude, and coordinates with a bidirectional lead screw and movable rod to adjust the clamping. Anti-slip sleeves enhance the clamping stability.

Benefits of technology

It effectively accelerates the stress release process, avoids structural damage, is compatible with workpieces of different sizes and complex contours, ensures clamping stability and device reliability, and enables convenient human-machine interaction control.
