Description

Technical Field

[0001] The utility model belongs to the technical field of welding, and in particular relates to a welding positioning fixture tool. Background Art

[0002] See attached Figure 1 In actual production, the column 8 needs to be welded to the body 3. Specifically, the body 3 is a cylindrical structure with one end open and the other end closed. The closed end of the body 3 is an outwardly convex arc surface. The column 8 needs to be eccentrically welded on the arc surface. At present, the welding method for this structure is that one person holds and fixes the column 8 and positions the column 8, while another person welds. This welding method not only has low welding efficiency and poor safety, but also leads to poor welding consistency and imprecise interfaces. Utility Model Content

[0033] The end of the positioning rod 5 that cooperates with the column 8 is truncated cone-shaped, and the small end of the truncated cone faces outward, so as to facilitate the end of the positioning rod 5 to be inserted into the positioning hole I of the column 8;
