Description

Technical Field

[0001] This utility model relates to the field of tank production technology, and in particular to an automatic clamping and rotating equipment for tank welding. Background Technology

[0002] During the tank manufacturing process, the tank body needs to be welded to form a single unit. Traditional welding fixtures require manual installation and adjustment. Due to the large size and heavy weight of the tanks being welded, the entire adjustment process is very cumbersome. Furthermore, traditional welding methods can only clamp and support the tank body, making it impossible to rotate it while welding to achieve circumferential welding, thus resulting in welding difficulties and low welding efficiency.

[0003] Patent CN120080091A discloses a hydraulic welding support fixture, including a base platform. A placement groove is formed at the center of the top of the base platform, and a worktable is movably arranged inside the placement groove. An inner cavity is formed directly below the placement groove, and a drive cylinder is installed inside the inner cavity. A first clamping mechanism is provided on the surface of the worktable. Support frames are fixedly installed on the top of the base platform and on both sides of the placement groove. A second clamping mechanism is provided on the surface of the support frames near their bottom ends, and a third hydraulic mechanism is installed at the top of the support frames. Although this equipment can clamp and position tanks of different models for welding, the large size of the tanks makes it difficult to place them on the fixture. Furthermore, the welding cannot be performed while rotating, requiring manual adjustment and resulting in low efficiency. Utility Model Content
