Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal welding, in particular to a sheet metal welding connection structure. Background Art

[0002] Sheet metal is a comprehensive cold working process for thin metal plates, including shearing, punching / cutting / combining, folding, welding, riveting, splicing, and forming (such as automobile bodies). Its most notable feature is that the thickness of the same part is consistent. The products processed by sheet metal processing are called sheet metal parts. Different industries generally refer to sheet metal parts differently, and the names are mostly used during assembly. Welding, also known as welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. The traditional way of connecting sheet metal parts is to connect the sheets together and directly connect bolts to the inside of the sheet metal. Over time, this will cause the sheet metal parts to be unstable and have poor stability.

[0003] Patent number CN217976980U, which has been published after searching, discloses a sheet metal welding connection structure, comprising a first sheet metal, a connector provided at the bottom of the first sheet metal, two first fixing blocks provided on one side of the first sheet metal, a second sheet metal provided on one side of the first sheet metal, a connecting sleeve fixedly connected to the interior of the second sheet metal, a second threaded sleeve provided inside the interior of the connecting sleeve, a second fixing block provided on both sides of the second sheet metal, a fixing plate provided on both sides of the second sheet metal, and a first bolt provided on one side of the second sheet metal. The advantages of the present invention are that the sheet metal welding connection structure is connected by the first fixing block, the second fixing block, the first fixing block, the second fixing block and the fixing plate, thereby solving the problem that the traditional sheet metal connection method is to connect the sheet metals together, which will cause the sheet metal to be unstable and have poor stability over time. However, there are still some disadvantages: the connection structure between the sheet metal parts is too cumbersome, requiring the worker to tighten the screws multiple times, which is relatively inconvenient. In addition, the existing device requires the worker to hold the sheet metal parts while welding, which is inconvenient and also poses a safety hazard. Utility Model Content
