Self-adaptive dismounting device for D-shaped bolt at tail end of space manipulator and working method of self-adaptive dismounting device

The invention discloses a space manipulator tail end D-shaped bolt self-adaptive dismounting device and a working method thereof, and belongs to the field of design of screwing dismounting devices for space station on-orbit services, and the space manipulator tail end D-shaped bolt self-adaptive dismounting device comprises two translation mechanisms, a rotating mechanism and a screwing mechanism; the two translation mechanisms are a transverse translation mechanism and a longitudinal translation mechanism which are perpendicular to each other; the rotating mechanism and the screwing mechanism are sequentially connected to the lower portion of the longitudinal translation mechanism. The transverse translation nut and the transverse translation lead screw are matched with the transverse translation sliding table and the transverse translation linear guide rail, and rotation of the transverse translation nut is limited through the transverse translation linear guide rail, so that the transverse translation slid
