Universal space docking mechanism with large tolerance

The invention discloses a universal space docking mechanism with a large tolerance. The universal space docking mechanism comprises a docking finger mechanism, a closing mechanism, a docking mechanismbase, a driving motor I, a driving motor II and a main driving lead screw, wherein the closing mechanism is connected to the docking mechanism base through the docking finger mechanism; the driving motor I and the driving motor II are arranged in a cavity of the docking mechanism base; and the driving motor I and the driving motor II are connected to the docking finger mechanism through the maindriving lead screw. The universal space docking mechanism with the large tolerance can simultaneously capture and dock a plurality of targets, and can reduce the relative position and attitude accuracy during docking at the same time so as to increase the tolerance of the docking. 本发明公开了种通用型大容差空间对接机构，包括：对接手指机构、收拢机构、对接机构基座、驱动电机Ⅰ、驱动电机Ⅱ和主驱动丝杠；收拢机构通过对接手指机构与对接机构基座连接；驱动电机Ⅰ和驱动电机Ⅱ设置在对接机构基座的腔体内，通过主驱动丝杠与对接手指机构连接。本发明能够同时对多种目标进行抓捕对接，同
