The invention provides a reinforcement principle non-redundant drive six-degree-of-freedom spacecraft docking and attitude adjusting system. The system comprises four supporting plates; the branch chain assembly comprises a first branch chain, a second branch chain, a third branch chain and a fourth branch chain; and a spacecraft cabin section is mounted at the top of the attitude adjusting table. The mechanism has the beneficial effects that the moving directions of the second moving pair P2 and the third moving pair P3 in each branch chain are perpendicular to each other and are parallel to the posture adjusting table, the included angles between the two moving pairs and the first main moving direction and the second main moving direction are both 45 degrees, and the included angle between the first moving pair P1 of each branch chain leg of the initial posture and the supporting plate is alpha (alpha is smaller than 90 degrees); when the three moving pairs on the branch chains are driving pairs, the driving force in the first main movement direction and the second main movement direction is increased through the arrangement mode, and the requirement for large loads of docking and attitude adjustment of the spacecraft is met.

    本发明提供了一种增力原理非冗余驱动六自由度航天器对接调姿系统,包括:4个支撑板;支链组件,所述支链组件包括第一支链、第二支链、第三支链、第四支链;调姿台,所述调姿台顶部安装航天器舱段。本发明有益效果:本发明的各支链中第二移动副P2和第三移动副P3运动方向彼此垂直并平行于调姿台,且此两移动副与第一主运动方向和第二主运动方向夹角均为45°,初始位姿每条支链腿的第一移动副P1与支撑板夹角为α(α<90°),支链上三个移动副为驱动副时此种布置方式使得第一主运动方向和第二主运动方向驱动力增大,达到航天器对接调姿大负载的要求。
