Resistance welding electrode capable of conducting locating

Abstract

The invention provides a resistance welding electrode capable of conducting locating. The resistance welding electrode capable of conducting locating is suitable for sheet metal, the lap joint sizes are identical, the number of the production steps can be reduced, and labor intensity can be relieved. The resistance welding electrode capable of conducting locating comprises an upper electrode body and a lower electrode body assembly. The upper electrode body is located above the lower electrode body assembly and can move vertically relative to the lower electrode body assembly. The lower electrode body assembly comprises a lower electrode body, a locating block and a shaft pin, the lower electrode body is arranged on the locating block through the shaft pin, the locating block is provided with a first locating groove, a second locating groove, a flow channel, an electrode hole and a plurality of fixing holes, the first locating groove and the second locating groove are located in the two side surfaces of the locating block, the fixing holes are formed in the upper surface of the locating block, the electrode hole is formed in one end of the locating block, the flow channel is located in the locating block, the first locating groove inclines downwards, and the second locating groove inclines upwards. By the adoption of the resistance welding electrode capable of conducting locating, the product quality is improved, the production cost and the labor intensity are lowered, and production efficiency is improved.

Description

technical field [0001] The invention relates to a resistance welding electrode, in particular to a positionable resistance welding electrode. Background technique [0002] At present, resistance welding has become an important connection method between metal components, mainly by applying pressure through electrodes between the combined workpieces, and welding by using the resistance heat generated by the current passing through the contact surface of the electrodes and the adjacent area. There are four main methods of resistance welding: spot welding, seam welding, projection welding and butt welding, among which spot welding and seam welding are more commonly used, while butt welding and projection welding have requirements on the parallelism and roughness of the welding surface of the workpiece. Higher, in the actual production process, the work efficiency is lower. "Spot welding", as the name suggests, is a small local welding. After welding, a welding spot is formed on...

Problems solved by technology

However, in the actual production process, it was found that there was a deviation in the diameter of the cylinder, which affected the next capping process, so that the upper and lower caps of the cylinder did not match the diameter of the cylinder, whether large or small, thus affecting the airtightness of the container. The reasons are: (1), the marking line is not accurate; (2), when the two welding surfaces overlap to form a lap joint, the marking line cannot be completely aligned for spot welding
