The invention discloses an on-orbit replaceable module butt joint locking/releasing mechanism, and belongs to the technical field of spacecraft on-orbit service. The structure comprises a butt joint module, a butt joint cabin plate, a second-stage tensioning and locking mechanism and a first-stage locking mechanism. Position errors of the active end and the passive end caused by the precision of the mechanical arm are compensated in a cone-rod type butt joint mode, and tolerance connection is achieved; the SMA spring driver and the spherical lock are adopted to realize multiple repeated butt joint and unlocking processes; a two-stage tensioning and locking mechanism is added to overcome large resistance which cannot be overcome by the mechanical arm in the connecting process; the universal flange is adopted, so that the universal flange can be installed on various butt joint modules, the butt joint locking process is completed, and modularization is achieved.

    本发明公开了一种在轨可更换模块对接锁紧/释放机构,属于航天器在轨服务技术领域。结构包括对接模块、对接舱板、二级拉紧锁定机构和一级锁定机构。本发明通过锥‑杆式对接方式补偿由于机械臂精度导致主被动端位置误差,实现容差连接;采用SMA弹簧驱动器和球形锁实现多次重复对接及解锁过程;加入二级拉紧锁定机构以克服在连接过程中的机械臂无法克服的较大阻力;采用通用式法兰使其可以安装于多种对接模块上,完成对接锁定过程,实现模块化。
