The invention relates to a method and to an installation for fitting nuts to a sheet-metal workpiece, by punching the nuts thereinto. In order to provide a rational and flexible nut punching system which can be readily adapted to serve mutually different workpieces, it is proposed in accordance with the invention that the workpiece is securely positioned in a fixture; that a portable nut punching tool is fitted to a tool attachment provided on the wrist of an industrial robot; that the robot positions the nut punching tool sequentially in pre-determined locations on the workpiece to which nuts are to be fitted; and that the nut punching tool is activated in such locations so as to punch nuts securely into the sheet-metal workpiece. |
