Title:
WELDING CONTROLLING METHOD FOR PROJECTION NUT AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JP3650931
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a safety countermeasure in case of a finger put by a guide rod in feeding a projection nut into an electrode by passing through a guide rod of a feeding rod in a state of skewering after stopping the projection nut at a prescribed position.
SOLUTION: The guide rod 17 of the feeding rod 6 is constituted so as to make relative displacement. For the relative displacement, the guide rod 17 is made to insert into the rod part 16 in a state capable of to-and-fro movement, and when the finger is put, the guide rod 17 is made to retreat relatively to avoid an injury. At the same time, by making the signal obtained by the relative displacement a trriger, the advancing of an electrode 2 is made to stop.
