PARTS FEEDING DEVICE FOR SPOT WELDING MACHINE

摘要

PURPOSE:To smooth and surely transfer a part by striking a guide member against the vertical wall of a part placing part by moving upto the closest position of a stationary electrode with placing the part on a part holding part. CONSTITUTION:Both the main and sub guide members 16, 17 are moving to the part of a part placing part 12 with placing a part 27 on a part holding part 24 without changing the relative position, because the main guide member 16 transmits the force being to the left part via a spring 21 by pushing to the left side the sub-guide member 17 by a piston rod 19, when a work cylinder 18 is driven. And when the tip part of the main guide member 16 collide with the vertical wall of the part placing part 12, the sub-guide member 17 transfers the part 27 onto the part placing part 12 wit its tip with compressing the spring 21 this time to make the state of clamping the part 27. Then, when a mobile electrode 30 is descended to the place where a worker is holding a steel plate 29, it comes into contact with the part 27 and the spot welding is completed with the pressurizing and electrification being performed.
