Abstract

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 device with the two ends hinged to the connecting platform and the connecting frame respectively. The main branch chain comprises a third linear driving device with the two ends hinged to the telescopic end of the first linear driving device and the motion platform correspondingly. The connecting frame is connected to the fixed base. The performance of the six-degree-of-freedom posture adjusting table is improved.

Description

technical field [0001] The present application relates to the technical field of attitude adjustment platforms, in particular to a redundantly driven six-degree-of-freedom attitude adjustment platform with branches and closed loops. Background technique [0002] In recent years, with the deepening of relevant theories of parallel mechanisms and the continuous expansion of application fields, parallel mechanisms have been widely used in virtual axis machine tools, micro-motion consoles, and various motion simulators. Compared with the series mechanism, the parallel mechanism has the following characteristics: compact structure; high rigidity; strong bearing capacity; small influence of cumulative error and high precision; the driving device can be placed on the fixed platform or close to the fixed platform. The position is beneficial to reduce the motion load, the system has low inertia and good dynamic response. Most of the existing six-degree-of-freedom attitude control pl...
