Research on the assembly method of missile based on laser scanning

The final assembly is the final and core link in the production process of the missile, and its assembly accuracy directly determines the production efficiency and quality of the product. However, the assembly of most cabins at present mainly relies on human visual inspection or with the help of measuring tools to ensure assembly accuracy, which results in poor assembly gap uniformity and low production efficiency. Aiming at the lateral assembly of small-diameter missiles, this paper proposes a method for measuring the deviation of missile assembly based on laser scanning. This method can measure the attitude deviation in the other 5 degrees of freedom except the roll angle, and finally carry out the missile assembly experiment. The experimental results show that the use of this measurement method can successfully complete the assembly of a cabin with a diameter of 160mm and a docking gap of only 0.2 mm.
