Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing auxiliary tools, in particular to a cylinder welding tool suitable for special-shaped end covers. Background Art

[0002] In the process of mechanical production and processing, it is often necessary to weld the cylinder and the end cap. In the prior art, the two are generally fixed separately by hanging, and then manually aligned and welded. The manual operation method is often difficult to ensure stability, resulting in difficulty in ensuring the consistency and accuracy of welding quality during the welding process. In addition, for some cases where end caps need to be welded at both ends of the cylinder, manual operation is difficult to ensure the symmetry of the end caps on both sides.

[0003] Chinese patent document CN213196327U discloses a welding fixture for pipe end caps, including a base plate, a support plate and a mounting ring are arranged on the base plate, and the end caps are positioned by using a plurality of positioning structures evenly arranged on the outer wall of the suction cup. When in use, the push rod is first pulled to extend the first spring, and then the end cap is placed between the clamps, and then the push rod is released. Under the action of the first spring, the push rod drives the clamp to move, and the end cap is clamped by the clamp. The above technical solution can avoid the defects of low stability and difficult welding quality caused by manual positioning, but the clamp in the technical solution is arranged around the outer circumferential wall of the suction cup. Therefore, when the shape of the end cap is irregular, the clamp cannot fix it, so manual positioning is still required. For irregular-shaped end caps, when the end caps at both ends of the cylinder are required to be symmetrical with each other, the efficiency and accuracy of manual positioning are obviously more difficult to meet the processing requirements.

[0004] Therefore, there is an urgent need for a welding tool that can clamp and position end covers of irregular shapes. Utility Model Content
