The utility model relates to the technical field of ship transformation, in particular to a
welding tool for a shell end cover, which comprises an operation table, two groups of positioning tools are mounted on the operation table, and each positioning tool comprises two groups of supporting components and a cover pushing component opposite to the corresponding supporting component. According to the
welding tool for the shell end cover, the supporting block is matched with the V-shaped block to achieve positioning of the shell, the
kidney-shaped hole design can adjust the position of the V-shaped block and adapt to stable supporting and limiting of shells of different specifications, the spring at the cover clamping end and the push block form an elastic clamping structure, the end cover can be clamped and fixed and prevented from moving up and down, and the ejection air cylinder drives the T-shaped block and the dragging plate to move horizontally. The dragging plate is matched with the end cover, axial positioning of the end cover and the shell is achieved, the alignment precision of
welding seams is ensured, the side pressing
assembly drives a connecting rod and a U-shaped plate through a direct pushing air cylinder, a pressing head is driven to press the shell, a side pushing air cylinder synchronously applies transverse pushing force, multi-dimensional clamping is formed, the displacement risk of a workpiece in the
welding process is eliminated, and the problems of welding seam
dislocation, insufficient welding and the like are solved.
