The invention relates to an on-orbit butt joint filling mechanism, and belongs to the technical field of aerospace. The mechanism is composed of a server side and a satellite side, electro-hydraulic double-medium butt joint is adopted, a floating butt joint technology is adopted, the capacity of tolerance adjustment, automatic centering, automatic recovery, connector locking, connector sealing and rapid disconnection of other five freedom degrees except the butt joint direction is achieved, and metal hard pipelines can be driven to be in butt joint. The mechanism is light in weight, simple and compact in structure and high in tolerance adjusting capacity, adopts a high-reliability dual-motor backup driving mode, and has very high practicability.

    本发明是一种在轨对接加注机构,属于航空航天技术领域。本发明的机构由服务端和卫星端两部分组成,为电液双介质对接,采用浮动对接技术,拥有除对接方向外其他五个自由度的容差调整、自动对中、自动回复、接口锁紧、接口密封及快速断接能力并且可以带动金属硬质管路进行对接。该机构重量轻、结构简单紧凑,容差调整能力大且采用可靠性高的双电机备份驱动方式,具有很强的实用性。
