Description

Technical Field

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

[0002] The clamping and welding limit of sheet metal parts are usually achieved by fixtures or molds. Fixtures usually consist of clamping devices and positioning devices, which are used to fix and position the sheet metal parts to be welded. Their design usually takes into account the accurate positioning and limit requirements of welding to ensure the correct position and stability of the sheet metal parts during welding. The design of the fixture may also include the function of realizing welding angle and weld width control. In terms of molds, in mass production, molds may be used to clamp sheet metal parts before welding.

[0003] The traditional sheet metal welding limiter usually consists of three main mechanisms: a positioning device, a clamping device, and a welding mold. The positioning device includes a positioning pin, a positioning block, and a positioning hole to ensure that the sheet metal can be accurately positioned in the appropriate position during welding. The clamping device fixes the sheet metal through a clamp to ensure that it maintains a stable position during the welding process. In large-scale production, a welding mold may be used to maintain the locking state of the sheet metal to ensure that the position is accurate and stable during the welding process.

[0004] However, the clamping device structure in the traditional sheet metal buckling welding limit structure is relatively simple, and sometimes it is unable to effectively fix the sheet metal. This results in displacement or instability of the sheet metal during welding due to lack of stable clamping, which leads to reduced welding quality and even welding deviation or poor welding. Therefore, a sheet metal buckling welding limit structure is proposed to solve the above problems. Summary of the invention
