【摘要】 为提高大型部件筒体-端框对接过程中的装配精度,研究了一种大型筒体-端框对接装配位姿计算与精确调整的方法。该方法利用大型筒段装配对接面的实际测量信息,建立了大型筒段位姿的数学模型,求解出筒体动态位姿的调整参量,进而实现了对大型筒段装配位置和姿态的精确调整,提高了对接装配精度和效率。通过某大型筒体-端框对接装配中的实际运用,表明所研究的大型筒段对接装配位姿调整方法满足了这类大型部件的对接装配精度要求。更多还原

【Abstract】 To get higher assembly accuracy during the assembly process of large cylinder and end-frame, a novel posture calculation and accurate adjustment method of butt assembly is proposed in this paper. After the measurement of the butt assembly surface, a mathematical model is established to describe the posture of the large cylinder, which is used to calculate the adjustment parameters to realize the precise adjustment of the posture of the large cylinder and improvement of precision and efficiency during the assembly process. The proposed method is applied to the butt assembly process of some large cylinder and end-frame. The results indicate that this posture adjustment method of large cylinder can meet the precision requirement of butt assembly of this kind of large parts.更多还原
