The invention discloses a high-rigidity connected allomorphic spatial docking mechanism, which is divided into an active end and a passive end and adopts allomorphic design, namely docking ports of the active end and the passive end are consistent in configuration. The butt joint port comprises a guide cone, a butt joint cone, a V-shaped groove, a V-shaped block and a central boss; the guide cone and the butt-joint cone are located in the center of the mechanism; the three groups of V-shaped grooves and V-shaped blocks are uniformly distributed at intervals in a circumferential array; the central boss is used as an axial displacement positioning structure; and the overall structure of the butt joint port has relatively strong geometric symmetry. The guiding cone-butt joint cone in the center of the butt joint mechanism enables the butt joint mechanism to have good tolerance performance. The circumferential V-shaped groove-V-shaped block enables the positioning precision to be high; the geometric symmetry of the interface is beneficial to establishment of a structure analysis equation and construction of an interface performance optimization function; due to structural redundancy caused by different-body isomorphic butt joint, the connection rigidity is enhanced, and the loading capacity of the mechanism is improved.
本发明公开了一种高刚度连接的异体同构式空间对接机构,该对接机构分为主动端和被动端,采取异体同构设计,即主动端和被动端对接口构型一致。对接口包括导向圆锥、对接圆锥、V型槽、V型块和中央凸台;导向圆锥和对接圆锥位于机构中央;3组V型槽和V型块周向阵列均匀间隔分布;中央凸台作为轴向位移定位结构;对接口整体结构具有较强的几何对称性。上述对接机构中央的导向圆锥‑对接圆锥使其具备较好的容差性能;周向V型槽‑V型块使其具备较高的定位精度;对接口几何对称性有利于建立结构解析方程,构造接口性能优化函数;异体同构式对接带来的结构冗余增强了其连接刚度,提高了机构的负载能力。
