Abstract
An automatic nut screwing device includes a positioning mold plate, a screw shaft, driving gear elements having driving gears, and transmission screwing elements having transmission screw gear units, bolt heads and bolt bodies. The transmission screw gear unit engages an upper out surface of the bolt head. The bolt head of each transmission screw element is fixed with the positioning mold plate. The shaft engaging portion engages with the transmission screw gear unit. The transmission screw gear unit engages with the driving gears such that the transmission screw gear unit is driven to rotate by the shaft engaging portion. A nut socket placing element has nut sockets when the screw shaft is axially rotated to enable the shaft engaging portion of the screw shaft to drive the transmission screw elements, thereby successively rotating elements that result in screw body being rotated to screw with the nut.
