PURPOSE:To facilitate the positioning of the fastener tightening device with respect to a main body and simplify incorporating process by a method wherein an engaging member, engaging with an incorporated component, and a guide member, engaging self-centripetally with a positioning part formed on the main body, are provided in the device. CONSTITUTION:An adaptor bracket 18, connected to the arm of the robot, is attached to the lower surface of a base plate 11 for the supporting unit M of a nut tightening unit N while a movable plate 12 is attached to the upper surface of the plate 11 through a floating mechanism 19. The supporting unit M consists of a floating amount set mechanism 14, setting the floating amount of the plate 12, the engaging member 16, engaging with an engaging hole, and the guide member 17, engaging with the positioning hole self-centripetally. The member 17 is energized by air through a piston 52 and the guide taper part 42a of a guide 42 is fitted into the positioning hole 3 under moving self-centripetally to stop the robot under this condition. |
