AI Technical Summary
Existing rocket propellant tank internal support devices suffer from problems such as poor operational safety, insufficient bending and unfolding capacity, poor structural synchronization, insufficient support stiffness, and lack of automated control capabilities during the welding process, making it difficult to meet the circumferential weld requirements of large thin-walled rocket propellant tanks.
A fully automatic circumferential welded internal support unfolding fixture was designed, including a drive and transmission assembly, an axial-radial conversion assembly, a multi-branch unfolding support assembly, a combined support assembly, and a support frame. It utilizes servo motors, lead screws, wedges, multi-branch unfolding support assemblies, sensors, and control units to achieve automated unfolding, support, and retraction, providing high rigidity, uniform support, and real-time monitoring.
It improves operational safety, ensures the stability and quality of the welding process, achieves multi-point synchronous and high-rigidity support, meets the welding requirements of large thin-walled rocket propellant tanks, reduces accident risks, and improves welding efficiency.
