The invention relates to an electrode assembly for nut projection welding. The electrode assembly comprises an upper electrode, a lower electrode installation base, a working spring, a lower electrodeand a positioning pin, wherein the upper electrode is connected to a welding machine air cylinder; the lower electrode installation base is disposed under the upper electrode, and a positioning groove is formed in the lower electrode installation base; the working spring is disposed in the positioning groove; the lower electrode is disposed on the lower electrode installation base; the positioning pin comprises a connecting end and a positioning end, the connecting end is connected to the working spring, and the positioning end passes through the lower electrode and extends out upwards; a to-be-welded board is penetrated by the positioning pin by a reserved hole formed in the board and is placed under the lower electrode; and a positioning bulge is disposed on the positioning end, and a to-be-welded nut is placed on the positioning bulge. In comparison with the prior art, the electrode assembly provided by the invention has the beneficial effects that through design of the positioningpin, a nut thread area and a working area on edges of threads are protected; and adhesion influences of splashing and spreading of liquefied metal on the nut thread area and the working area on the edges of the threads can be avoided.
Description
technical field [0001] The invention relates to an electrode assembly, in particular to an electrode assembly for nut projection welding. Background technique [0002] With the rapid development of the automobile industry, the demand for high efficiency and individualization is becoming more and more obvious. In the automobile manufacturing process, welding nuts using projection welding technology can accurately locate the welding position of the nuts and improve welding quality. Correspondingly, carbon dioxide gas shielded welding is more It can reduce the harm of harmful gases to the human body, so projection welding is widely used in the automotive industry, but welding defects caused by various factors in the welding process also have a great impact on the production environment. [0003] The welding slag of the projection welding nut has become a defect that is difficult to solve in the welding process. The welding slag is easy to damage the thread, which brings difficu...
