The invention relates to the technical field of aerospace, in particular to an on-orbit service tool fixing device which comprises a base, a limiting mechanism, a locking piece and a hot work cutter, the limiting mechanism is arranged on the base, the tool is limited on the base by being connected with the tool, and the limiting mechanism comprises a fixed limiting part and a movable limiting part; the movable limiting part is used for enabling the tool to be detachably connected with the base; the locking piece is arranged on the base and is connected with the fixed limiting part, so that the fixed limiting part is limited on the base; the hot working cutter is arranged on the base and used for disconnecting the fixed limiting part and the locking piece. The tool is rigidly supported through the fixed limiting part, the tool is supported in a floating mode through the movable limiting part, the movable limiting part buffers the upward impact load in the launching stage for the fixed limiting part, it is ensured that the fixing device can bear the vibration impact load in the upward movement process, and meanwhile the number of hot work cutters needed by a single tool is reduced; and the condition of shortage of electrical interface resources of the spacecraft is relieved.

    本申请涉及航空航天技术领域,尤其涉及在轨服务工具固定装置,装置包括基座、限位机构、锁固件和火工切割器,限位机构设置于基座上,通过与工具连接使工具限位于基座上,限位机构包括固定限位部和活动限位部,活动限位部用于使工具与基座可拆卸连接;锁固件设置于基座上,通过与固定限位部连接使固定限位部限位于基座上;火工切割器设置于基座上,用于断开固定限位部与锁固件之间的连接。本申请通过固定限位部对工具刚性支撑,通过活动限位部对工具浮动支撑,活动限位部为固定限位部缓冲发射阶段的上行冲击载荷,确保固定装置可承受上行过程中振动冲击载荷,同时减少单个工具所需要的火工切割器的数量,缓解了航天器电接口资源紧张的状况。
