摘要：

为解决飞机数字化装配中难以对机身大部件增加辅助固持并保持大部件位姿不变的技术难题,提出一种基于气浮和万向球座的大部件位姿跟随固持方法,并设计制造称之为随动定位器的专用柔性工装.结合某工程,进行定位器关键参数的分析计算和相关工艺试验研究,并对油压波动、相关零件磨损对锁紧力的影响以及芯轴自由端关键参数选择与入位可靠性问题进行了研究.结果表明,在芯轴角度偏差较小时,随动定位器可以在确保大部件位姿不被破坏的情况下,实现芯轴的小阻力自适应入位,并可以根据选定的工作油压和配合间隙可靠固持大部件,其性能可以满足工程要求.
Abstract:

In order to keep and fasten reliably the adjusted posture of large components such as fuselage in aircraft digital assembly, a new adaptive posture following and keeping fixture of large components, based on the principle of aerostatic bearing and universal ball joint, was proposed, and a new flexible fixture called posture following and keeping fixture was developed. The influences of pressure fluctuation and component abrasion on axial clamping force, and the relationship between the reliability level of the mandrel adaptively introducing into the thin-wall barrel and the structure and dimension of the mandrel free end were studied. The theoretic analysis and experiments results show that this method is feasible and reliable for posture following and keeping in relation to different kind of conditions and parameters, and the mandrel can adaptively introduce into the thin-wall barrel on condition that the angle deviation of the mandrel is small．
