[0002] In the process of the vigorous development of the modern packaging machinery industry, welding, as a key process for connecting and assembling mechanical parts, the performance of its device is directly related to the quality, production efficiency and reliability of the entire packaging machinery. The first problem of the traditional packaging machinery welding device is poor clamping adaptability. Packaging machinery is composed of a large number of mechanical parts of different sizes and shapes, such as various rod parts, block structures and parts with special curved surfaces or tapers. The clamping mechanism of the traditional welding device often adopts a design of fixed size or limited adjustment range, which is difficult to quickly and accurately adapt to the clamping requirements of such diversified parts. When facing mechanical parts of different specifications, manual replacement of clamping tools or tedious temporary adjustment is often required, which not only consumes a lot of time and labor cost, but also easily leads to insecure clamping or position deviation of the parts due to improper adjustment, thereby affecting the welding quality, increasing the scrap rate and seriously restricting the standardization and scaling process of packaging machinery production.

[0003] The above information disclosed in the background of the application is only used to increase the understanding of the background of the application, and therefore, it can include prior art known to those skilled in the art. CONTENT OF THE UTILITY MODEL
