[Abstract]:The machining area of aircraft moving wing surface is relatively wide, the task of making holes is heavy, the efficiency of making holes by hand is low, and the machining precision is difficult to guarantee, the cost of adopting special machine tools will be very high. In this context, a robotic drilling system based on air cushion transportation is proposed in this paper. The moving wing surface is divided into 14 working areas, which depend on air cushion transportation to carry out processing tasks respectively. The main contents of this paper are as follows: in chapter 1, the research background and significance of the thesis are described, and the development status of automatic hole making system in aircraft assembly is summarized, and the application technology of air cushion transportation technology in aircraft assembly is expounded. The research content of this paper is put forward. In chapter 2, the working principle of air cushion vehicle is introduced, the key technology of air cushion transportation is put forward, the technical requirements of air cushion vehicle design are put forward, and the detailed design scheme of air cushion vehicle platform is given. In the third chapter, the function and requirements of the hole making equipment based on air cushion transportation are introduced in detail. Then it introduces the key components of the hole making equipment, including the moving platform of the air cushion vehicle, the industrial robot and the knife storehouse, and emphatically introduces the hardware and software of the terminal actuator control system. At the same time, the control process of hole making process is put forward. Finally, several key techniques of hole making process are studied and analyzed. Chapter 4 mainly introduces the software component of the automatic hole making system of active wing surface. According to the different functions of each module and different technological process, the interface and operation flow of the software are introduced in detail. In chapter 5, four kinds of cutting tools (4.1mm / 5.1mm / 5.88mm and 7.88mm) were used to process carbon fiber composites and the tool wear tests were carried out at the same time. It is concluded that when the spindle speed is 10000rpm, the feed speed is 200mm / min, the hole making quality is good, there is no obvious delamination defect, and the surface roughness Ra3.2, can meet the higher precision requirement. When using cemented carbide bit, tool wear is slow, 120-150 holes can be machined. Chapter 6 summarizes the full text and looks forward to the next research direction.
