Abstract

This invention discloses a laser processing system for aerospace composite materials, relating to the field of aerospace manufacturing technology. The system includes a processing table, an adjustment mechanism, a processing mechanism, and an ultrasonic vibration mechanism. The processing table includes a worktable for providing space for material placement. The invention provides a mounting position for the ultrasonic vibrator via a mounting sleeve, and a telescopic assembly is symmetrically mounted on the mounting sleeve. A telescopic plate is telescopically connected to the inner side of the telescopic assembly, and a vibration ring is mounted at the bottom. This facilitates the generation of high-frequency vibration by the ultrasonic vibrator, which is then transmitted through the mounting sleeve, telescopic assembly, and telescopic plate to the vibration ring. The vibration ring fits snugly against the processing location, allowing for simultaneous high-frequency vibration operation during processing. This helps reduce the material's hardness and viscosity, promotes the removal of slag and fumes, reduces heat accumulation, and improves processing quality and efficiency.
