Process for automatically exchanging electrode caps at weld electrode shafts, and device for carrying out the process

摘要

1. A method of automatically changing electrode caps on welding-electrode shanks secured to loom drivers or electrode holders in welding robots, the electrode cap for changing being firmly clamped and rotated and, after the electrode cap has been pulled off, the welding-electrode shank is moved to an electrode cap store where it is inserted into an electrode cap and then hammers it firm, characterized in that, in order to pull of the electrode cap, the welding-electrode shank is preventing from twisting while being rotated by the welding robot, and the welding-electrode shank of electrode cap is simultaneously pulled back.
