摘　　要：K型精密锁紧螺母广泛应用于需强力、安全锁紧的精密机构中,借助工业机器人进行自动化装卸,可大大减轻工人劳动强度。根据K型精密锁紧螺母结构特点及装配的工艺要求,设计了一种末端执行器机械结构,并导入ANSYS Workbench中对模型进行静力学分析、模态分析,静力分析结果表明末端执行器受到的最大应力为61.86MPa,结构强度满足要求;模态分析得出末端执行器结构的6阶固有频率和振型,与6轴电机激励频率相差较大,验证了该末端执行器工作的合理性。K-type precision lock nut is widely used in precision mechanisms that require strong and safe locking,and automatic loading and unloading with the help of industrial robots can greatly reduce the labor intensity of workers.According to the structural characteristics of the K-type precision lock nut and the process requirements of the assembly,a mechanical structure of the end effector is designed,and the static analysis and modal analysis of the model are introduced into ANSYS Workbench,and the static analysis results show that the maximum stress of the end effector is 61.86MPa,and the structural strength meets the requirements;The modal analysis shows the 6th-order natural frequency and mode shape of the end effector structure,which is quite different from the excitation frequency of the 6-axis motor,which verifies the rationality of the operation of the end effector.
