摘要
在对惯性约束核聚变(ICF)靶支撑定位功能分析的基础上,设计并制造了一套用于靶精密定位机器人系统,主要包括靶库机构、换靶机构、送靶机构和6自由度精密并联机器人机构,论述了各部分的工作原理和组成。系统在末端采用并联机器人来实现对靶的精密定位,测试了靶场环境下系统的运动指标。测试结果显示:系统可在真空条件下实现对靶的精确定位、换靶、送靶工作,靶定位精度达到μm级,定位时间随精度的提高而延长。
Based on the function analysis of target positioner for inertial confinement fusion, a kind of ICF target positioning robot system is designed to realize the adjustment and the alignment of a target. The robot system includes a target storage subsystem, a target exchange subsystem, a target transport subsystem and a 6-degree of freedom precision parallel robot subsystem, the structure and principle of every subsystem are dissertated. The system realizes micro scale position by parallel structure which is in the front of the system, and has the advantages of low mass, high stiffness, small cone angle, small volume and high precision. The robot system can position a target into a very small micro scale scope around the center of the target chamber whose diameter is several meters, the precision of the position reaches micro scale. Motion parameter of the positioning robot system has been tested. Experiment proves that the robot system has realized precision target position and target exchange on the condition of vacuum.
