【摘要】：飞机活动翼面加工区域比较广,制孔任务繁重,依靠手工制孔效率低下,并且加工精度难以保证,采用专用机床成本将非常高昂。在此背景下,本文提出一套基于气垫运输的机器人制孔系统,将活动翼面分为14个工作区域,依靠气垫运输,分别进行加工任务。本文研究内容如下：第1章主要阐述论文的研究背景和意义,总结了飞机装配中自动制孔系统的国内外发展现状,在阐述气垫运输技术在飞机装配中应用技术的基础上,提出了论文的研究内容。第2章主要阐述气垫车的工作原理,同时提出气垫运输的关键技术；结合本项目需求,提出气垫车设计的技术要求,并给出气垫车平台的详细设计方案。第3章首先详细介绍基于气垫运输的活动翼面制孔设备的功能以及制孔区域要求；然后介绍制孔设备的关键组成部分,包括气垫车移动平台、工业机器人以及刀库等,并着重介绍末端执行器硬件和软件两方面的控制系统组成,同时提出制孔过程控制工艺流程,最后对制孔过程的几项关键技术进行研究分析。第4章主要介绍活动翼面自动化制孔系统软件的组成部分,根据各个模块的不同功能以及不同工艺流程,对软件各个界面和操作流程分别作了详细介绍。第5章主要对碳纤维复合材料,分别用4.1mm、5.1mm、5.88mm和7.88mm四种规格的刀具进行加工试验,同时进行刀具磨损试验。得到结论：当主轴转速10000rpm,进给速度200mm/min,制孔质量良好,无明显分层缺陷,表面粗糙度Ra3.2,能够满足较高精度要求；采用硬质合金钻头进行加工时,刀具磨损较为缓慢,可以加工120-150个孔。第6章对全文进行总结,并就下一步研究方向作了展望。
[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.
