According to the high-precision multi-stage telescopic mechanism, a base, moving seats and a construction seat are all of frame structures, the base is installed at a fixed position, the multiple moving seats are arranged on the base and sequentially connected end to end, and the construction seat is installed at the moving seat execution end away from the base; the movable seats move relative to the base and the construction seats or move relative to the base and the construction seats pairwise through transmission assemblies, and the base, the movable seats connected end to end and the construction seats are connected in series to form a tower body with the telescopic length. According to the high-precision multi-stage telescopic mechanism, long-stroke movement is achieved through the telescopic multi-stage unfolding structure, the base, the moving seat and the construction seat are all of frame nested structures, the number of layers of the nested structures can be infinitely increased to n according to the actual distance requirement, and the structure has the beneficial effects of being large in bearing capacity, high in precision and long in stroke; particularly, the mechanism has a wide application prospect in the fields of semi-physical simulation of spacecrafts, civil goods and the like in a high-precision motion control occasion.

    本发明提供了一种高精度多级伸缩机构,基座、移动座和施工座均为框架结构,基座安装至固定位置,基座上设置若干移动座,且若干移动座依次首尾相连接,远离基座的移动座执行端安装施工座,且移动座通过传动组件与基座、施工座或两两相对运动,基座、若干首尾相连接的移动座和施工座串接后构成长度可伸缩的塔体。本发明所述的一种高精度多级伸缩机构,通过可伸缩多级展开结构实现了长行程运动,基座、移动座和施工座均为框架嵌套结构,该嵌套结构层数可以根据实际距离需求无限扩展到n层,该结构具有大承载、高精度和长行程的特点,尤其使用高精度运动控制场合,该机构在航天器半物理仿真领域和民品等领域都具有广泛的应用前景。
