Problems solved by technology

[0003] At the same time, with the development of the automobile manufacturing industry, the production capacity of projection welded parts is getting higher and higher. In the past, the projection welded parts were only projected welded with nuts, bolts and plates, especially on a not too large plate at the same time. Welding multiple bolts and using separate welding, the welding efficiency is low and the labor intensity is high

Abstract

The invention relates to the technical field of electrodes, in particular to a floating simultaneous-four-point-projection-welding upper electrode structure which comprises a baseplate, shaft seats, a steering shaft seat, upper electrode head seats and an upper electrode body. Compared with the prior art, the floating simultaneous-four-point-projection-welding upper electrode structure has the advantages of simple structure, reliability in positioning, convenience in machining and high rigidity, the manufacturability problem of the projection-welding upper electrode structure is solved, welding of multiple bolts and a plate can be completed in one step, the welding process is stable and reliable, welding quality is stable, production efficiency is improved, and production cost is lowered; welding quality is guaranteed effectively, so that welding heat energy input can be lowered properly, and energy resources are saved; whenever the end face of an upper electrode head is worn, a user only needs to restore flatness of the end face, so that reusability of an upper electrode is improved, projection-welding electrode manufacturing cost is lowered, and tool maintainability is improved.

Description

technical field [0001] The invention relates to the technical field of electrodes, in particular to a floating four-point simultaneous projection welding upper electrode structure. Background technique [0002] In the current design of metal structural parts of automobiles and household appliances, direct projection welding of metal parts or nuts and bolts to another part has begun to be used, especially in the design of frame structural parts of automobiles, it has been widely used to improve production efficiency. , Reduce labor intensity. [0003] At the same time, with the development of the automobile manufacturing industry, the production capacity of projection welded parts is getting higher and higher. In the past, the projection welded parts were only projected welded with nuts, bolts and plates, especially on a not too large plate at the same time. If multiple bolts are welded and welded separately, the welding efficiency is low and the labor intensity is high....
