Abstract (en)

A screwing device with which fixing elements having a respective generated surface, in particular polygonal nuts, can be screwed onto studs. The screwing device can be driven electrically or pneumatically and comprises an exchangeable magazine which is provided in the screw axis and from which the individual nuts can be brought to a work station by means of a tool in the form of three arms. In this position, the polygonal nut and tool are positively fixed before the rotational movement is transmitted. The force is transmitted from the motor via a driving unit to the lifting cylinder and to the mouth-piece fixed thereon. <IMAGE>
