Abstract
A lower electrode of a spot welding machine comprises a first cylindrical part, a second cylindrical part and a third cylindrical part, which are arranged in sequence. The first cylindrical part, the second cylindrical part and the third cylindrical part are coaxial. Holes are separately formed in the centers of the first cylindrical part, the second cylindrical part and the third cylindrical part. The external diameter of the third cylindrical part is larger than the internal diameter of the second cylindrical part. The external diameter of the third cylindrical part is smaller than that of the first cylindrical part. The lower end of the third cylindrical part is chamfered. A boss is arranged above the first cylindrical part. The external diameter of the boss is equal to that of the first cylindrical part. The internal diameter of the boss is smaller than that of the first cylindrical part. A tubular KCF core is arranged on the inner circumferential surfaces of the first cylindrical part, the second cylindrical part and the third cylindrical part. The KCF core is in interference fit with the first cylindrical part, the second cylindrical part and the third cylindrical part. The lower electrode is skillful in design, firm to fix, high in insulating property, long in service life, and low in cost.
