摘要
使用基于修正雅可比旋量模型的容差分析方法,对引导锁C形闩机构中C形闩的安装位置、运动精度进行分析,与 3DCS软件结果进行对比,验证方法适用性.引用机器人运动学相关理论,将静态容差分析拓展到动态容差分析,对C形闩在运动过程中的位置精度进行分析,使用基于Taguchi的容差贡献度、灵敏度对其进行优化分析及容差设计,得出影响较大的因子.
Abstract
By the tolerance analysis method based on the modified Jacobian screw model,analyzes the installation position and motion accuracy of the C-shaped latch in the C-shaped latch mechanism of the guide lock,compares their results with the ones by 3DCS software to verify the applicability of the method.The kinematics theory of the robot is applied to extend the static tolerance analysis to the dynamic tolerance analysis,the position accuracy of the C-shaped latch in the process of motion is analyzed,and the Taguchi based tolerance contribution degree and sensitivity are used to optimize the analysis and tolerance design,obtaining the factors with greater influence.
