Projection Nut Feeding Device

摘要

A projection nut feeding device ensuring that a threaded hole in a projection nut accurately coincides with an electrode guide pin. The front end of a feed rod ( 6 ) is provided with a projecting piece ( 31 ) for supporting a multi-sided projection nut ( 1 ) from below in such a manner that the projecting piece ( 31 ) is in intimate contact with the outer side surfaces ( 35 ) of the nut ( 1 ). The inner side of the projecting piece ( 31 ) is formed with crossed support surfaces ( 37 ) for supporting the outer side surfaces ( 35 ) of the nut ( 1 ). The corner lines ( 38 ) in the place where the two support surfaces ( 37 ) cross each other is arranged to be directed to the underside of the feed rod ( 6 ).
