The invention provides a spacecraft on-orbit six-degree-of-freedom adjusting device and a using method. The spacecraft on-orbit six-degree-of-freedom adjusting device comprises an upper adapter bracket, a lower adapter bracket and six actuating assemblies, the axes of every two actuating assemblies are symmetrically arranged in pairs according to a certain included angle; the upper end of a single actuating assembly comprises a hooke joint, the lower end of the single actuating assembly comprises a hooke joint and a rotating shaft joint, and the single actuating assembly is fixedly connected with an adjusted object through an upper adapter bracket and is fixedly connected with the fixed base through a lower adapter bracket; the six-degree-of-freedom high-precision position and posture adjustment of an adjusted object can be realized through the axial extension and retraction of the actuator positioned in the middle; the method is suitable for spacecraft components such as satellite-borne reflector antennas and space telescopes which have high requirements on pose keeping precision or orientation adjusting precision; the device has the advantage of high precision under six-degree-of-freedom large-range adjustment, is high in modularization and generalization degree, and has very high adaptability to different layout scenes.
本发明提供了一种航天器在轨六自由度调整装置及使用方法,包括上转接支架、下转接支架和六支作动组件;每两支作动组件轴线按一定夹角成对对称布置;单个作动组件上端包含一个虎克铰,下端包含一个虎克铰和旋转轴关节,通过上转接支架与被调整对象固连,通过下转接支架与固定底座固连;通过位于中间的作动器的轴向伸缩,可实现被调整对象的六自由度高精度位姿调整;适用于星载反射面天线、空间望远镜等对位姿保持精度或指向调节精度要求较高的航天器部件;本发明在六自由度大范围调整下具有高精度的优势,并且模块化、通用化程度高,对不同的布局场景具有很强的适应性。
