Title:
SUPPLY DEVICE FOR PROJECTION NUT
Document Type and Number:
Japanese Patent JP3306579
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain smooth operation without interfering protrusions for welding each other, when a supply rod is advanced, by forming a recessed part to receive a projection nut at a tip part of a supply rod as opening downward, arranging a regulating face to set a up/down position of the projection nut and a vertical wall to set a center position at the recessed part and shifting a height position positioned by the regulating face more upward than a protrusion for welding of a succeeding projection nut.
SOLUTION: When a control pin 17 is retreated and a nut 12 is slid on a bottom plate of a supply tube 6 to reach an opening part 8, attraction force of a magnet attraction means 15 is applied to the nut, the nut is brought into contact with both the regulating wall 10 and the vertical wall, a vertical direction and a center position of the nut 12 is set at a right relative position against the recessed part 9 of a supply rod 1. Because the attracted position is higher than the nut on the succeeding bottom plate 7, the protrusions 13 for welding are not interfered each other.
