The invention discloses an auxiliary walking device for rehabilitation training and core component assembling equipment thereof, and belongs to the technical field of rehabilitation training. The auxiliary walking device comprises symmetrically arranged guide rails, the guide rails are supported by supporting columns, supporting bottom rings are movably arranged on the guide rails on the two sides, the supporting bottom rings on the two sides are of arc-shaped structures and can be in butt joint, and rotating rings are movably arranged on the supporting bottom rings; the rotating ring is of an arc-shaped structure, a telescopic column is arranged on the upper surface of the rotating ring, a supporting part is arranged at the top end of the telescopic column, a pull rod is hinged to the telescopic column, one end of the pull rod is connected with a pull wire, a supporting rod is arranged on the outer side of the rotating ring, a liftable connecting column is arranged on the supporting rod, and a roller is arranged at the bottom of the connecting column and located in a guide groove of the guide rail. The top of the connecting column is connected with the stay wire. And in addition, transfer of the supporting bottom ring, butt joint of the supporting bottom ring and the rotating ring and discharging after butt joint can be achieved through the assembling equipment, a transfer device in the middle can be greatly simplified, continuous and rapid production is achieved, the equipment cost can be reduced, and the production efficiency can be improved.
