The invention relates to the technical field of on-orbit maintenance mechanisms, in particular to a space camera on-orbit maintenance mechanism which comprises a base, a movable block, four roller rolling blocks, a guide check block, magnetic steel and a Hall device, the base is connected with a main optical machine structure, a square inner cavity is formed in the base, the four roller rolling blocks are fixed to the four surfaces of the square inner cavity of the base through screws, and the guide check block is connected with the magnetic steel. The movable block is arranged in the square inner cavity by being in interference fit with the roller rolling block; the guide stop block is arranged at the front end of the base and is used for guiding when the movable block is butted with the roller rolling block; the magnetic steel is arranged at the front end of the movable block, the Hall device is correspondingly arranged at the front end of the base, and the relative position relation between the movable block and the base is fed back through cooperation of the magnetic steel and the Hall device. The two-way high bearing and one-way freedom degree release device realizes two-way high bearing and one-way freedom degree release, has the advantages of high positioning precision, high repeated mounting precision, high operability, simple structure, low cost and the like, and is particularly suitable for being applied to scenes requiring high resetting precision, high bearing and one-way freedom degree release.
本发明涉及在轨维护机构技术领域,具体提供一种空间相机在轨维护机构,包括:基座、动块、滚柱滚动块、导向挡块、磁钢和霍尔器件,基座与主光机结构连接,其上开有方形内腔,四个滚柱滚动块通过螺钉固定在基座方形内腔的四个表面,动块通过与滚柱滚动块过盈配合设置在方形内腔内;导向挡块设置在基座的前端,用于在动块和滚柱滚动块对接时起导向作用;磁钢设置在动块的前端,基座的前端对应设置有霍尔器件,通过磁钢和霍尔器件的配合反馈动块与基座的相对位置关系。本发明实现了双向高承载和单向释放自由度,具有定位精度高、复装重复精度高、可操作性强、结构简单和成本低等优点,尤其适合应用在要求复位精度高、承载高、单向自由度释放的场景。
