Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a multifunctional welding positioner. Background Technology

[0002] With the rapid development of modern industrial technology, welding technology is increasingly widely used in fields such as machinery manufacturing, aerospace, and automobile manufacturing. In the manufacturing process of heavy equipment, welding long welds and circumferential welds is an indispensable step. However, traditional welding methods often require the use of overhead cranes to rotate the workpiece to find a suitable welding position. This method is not only inefficient but also poses significant safety hazards, making it difficult to ensure that the workpiece, welding machine, and welding worker are in optimal operating positions. Therefore, there is an urgent need in the market for an auxiliary device that can automatically adjust the workpiece position to achieve the ideal welding angle.

[0003] Multifunctional welding positioners have emerged to meet this need. They can use various movements such as lifting, rotating, and translating to bring a workpiece fixed on a worktable to the required welding angle. This equipment not only improves welding efficiency but also significantly reduces the labor intensity and safety risks for workers. However, existing multifunctional welding positioners still have some shortcomings in terms of functional completeness, ease of operation, and stability, making it difficult to meet the market's demand for high-quality, high-efficiency welding equipment.
