Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts tooling, and specifically relates to a welding tooling positioned by an electromagnet. Background Art

[0002] In modern industrial production, welding, as a key connection technology, is widely used in many fields such as machinery, electronics, automobiles, aerospace, etc. In order to improve the welding efficiency and accuracy, the design of positioning welding tooling becomes particularly important. Among them, a common tooling design idea is to inlay strong magnet blocks on the tooling positioning blocks, and use the magnetic force of permanent magnets to adsorb parts, so as to achieve the precise clamping and positioning of parts. However, although this design improves the welding convenience and efficiency to a certain extent, there are still many problems to be solved in the existing positioning welding tooling.

[0003] 1. Problem of iron powder adsorption. During the welding process, high temperature will cause the metal surface to oxidize, evaporate or sputter, forming fine iron powder particles. Due to the strong adsorption force of the permanent magnet, these iron powder particles are extremely easy to be adsorbed on the tooling positioning block and the part surface. As time goes by, the iron powder accumulates continuously, and will gradually form protrusions on the tooling surface, seriously affecting the dimensional positioning accuracy of the parts. In addition, these iron powder particles are also difficult to clean thoroughly, further increasing the maintenance cost and operation difficulty.

[0004] 2. Problem of magnetic force control. Most of the existing positioning welding tooling uses permanent magnet blocks with fixed magnetic force, and the flexible control of magnetic force cannot be realized. During the welding process, once the magnetic force is turned on, it is difficult to adjust its magnitude or turn it off according to needs, which is not conducive to the precise control of automatic welding jigs. Especially in scenarios where parts need to be frequently replaced or the welding position needs to be adjusted, the fixed magnetic force design is particularly inconvenient, restricting the flexibility and automation degree of the welding process.

[0005] 3. Problem of insufficient magnetic force intensity. Although the permanent magnet block has a strong adsorption force, in some special working conditions, its magnetic force intensity may not meet the requirements of precise part positioning. Especially in occasions that require high-precision welding, such as the aerospace and precision instrument fields, the magnetic force of the permanent magnet block may not be sufficient to ensure the close fit between the positioning surface and the part, thus affecting the welding quality and stability. In addition, with the extension of the service time and the change of the working environment, the magnetic force of the permanent magnet block may gradually weaken, further reducing the positioning accuracy.

[0006] To sum up, although the existing positioning welding tooling improves the welding convenience and efficiency to a certain extent, there are still problems such as iron powder adsorption, inconvenient magnetic force control and insufficient magnetic force intensity. In order to solve these problems, it is necessary to develop a new type of positioning welding tooling to improve the welding quality and efficiency by realizing the precise clamping and positioning of parts.
