摘要(Abstract):

飞机的除漆、再涂装,是其大修的重要环节。传统工艺都是采用化学工艺:即用脱漆剂腐蚀除漆。为了改变传统化学工艺的腐蚀、污染和人工作业的缺点,笔者研究了物理工艺,即采用200MPa、250kW的超高压旋转水射流,借助六轴机器人配置平面清洗器对飞机大表面和小曲面除漆作业。飞机的涂装层极其薄而致密,采用水射流除漆面对的矛盾是:均匀除去漆层而不损伤飞机铝合金表面。要做到这一点就必须试验得出最优化工况,即超高压参数下的除漆效率和不损伤表面的横移速度。本项试验横移速度约2m/min,除漆效率30~40m2/h,除漆有效面积达到85%~90%。执行机构的不重复、不遗漏是机器人示教编程的基本要求。物理除漆工艺即将运用于飞机维修,它将面临因水射流对飞机表面的打击安全检测的应用许可验证。
The paint removal and recoating are the very important process in airplane maintenance. The traditional technology is to use the chemical way corroding the paint with paint remover. For changing the defects,corrosion & pollution & manual working,of the traditional technology,the physical process which removes the paint of airplane with 200MPa /250kW high pressure rotary water jet though the plane cleaner installed on the six axis robot is studied. The paint layer of airplane is very thin and close. The contradiction of water jet paint removal is to remove the paint layer evenly and not damage the surface of airplane. In order to solve the contradiction,the best working condition must be reached through tests. The paint removal efficiency with ultra-high pressure and move speed of not damaged to the surface. The move speed of this test is about 2m / min,and the paint removal efficiency is 30 ~ 40m2/ h,and the paint removal active area is 85% ~ 90%. No-repeat and no-omit are the based requests of the robot program. The physical pant removal technology will be applied in airplane maintenance,and will face the safety detection of application permission.
