Redundant drive six-degree-of-freedom posture adjusting table with branches containing closed loops

The invention discloses a redundant drive six-degree-of-freedom posture adjusting table with branches containing closed loops, and relates to the technical field of posture adjusting tables. The redundant drive function is achieved, and the performance of the parallel mechanism can be improved. The six-degree-of-freedom posture adjusting table comprises a fixed base, a moving platform and three system branch chains which are evenly distributed between the fixed base and the moving platform in the circumferential direction. The system branch chain comprises a core branch chain, a main branch chain, an auxiliary branch chain and a connecting frame. The core branch chain comprises a first linear driving device and a connecting platform, and the connecting platform is arranged at the fixed end of the first linear driving device; the two ends of the first linear driving device are hinged to the moving platform and the connecting frame correspondingly. The auxiliary branch chain comprises a second linear driving de
