Abstract

The invention relates to an easy-to-replace projection welding electrode. The easy-to-replace projection welding electrode comprises an upper electrode mounting base, an upper electrode worm, an upperfixed electrode and an upper connecting electrode. The upper electrode mounting seat is fixedly connected with the upper electrode worm, and the upper electrode worm is in transmission connection with the upper fixed electrode. An internal thread mounting hole is formed in the bottom of the upper fixed electrode, an external thread mounting table is arranged at the top of the upper connecting electrode, and the upper fixed electrode is detachably connected with the upper connecting electrode through the internal thread mounting hole and the external thread mounting table. Compared with the prior art, the method has the advantages of convenience, rapidness, high matching precision, high universality, wide application range and the like.
