[0002] As Figure 1-2 shown, the workpiece includes an inner sleeve and an outer cover. A gap is formed on one side of the outer cover. The outer cover first covers the inner sleeve and then the two are assembled by welding. Before welding, the outer cover needs to be sleeved on the inner sleeve and fixed before the welding operation can be carried out. The traditional way to position the two is to manually use pliers to clamp them. However, since the wall thicknesses of both the outer cover and the inner sleeve are very thin, deformation of the outer cover and the inner sleeve is likely to occur during the clamping process, resulting in scrapping of the welded workpiece. Moreover, the method of manually operating the pliers for fixation is very slow, leading to low production efficiency. Summary of the Utility Model

[0023] Embodiment

[0024] Refer to Figure 1-4As shown in the figure, the utility model discloses a welding positioning tooling, which includes a bottom plate 10. A fixing block 101, a moving block 102, a pressing rod 103 and a pushing rod 104 are installed on the bottom plate 10. Specifically, a positioning block in a concave shape is installed on the bottom plate 10. Upper stoppers and lower stoppers are respectively arranged at both ends of the positioning block along the length direction. Through holes for the pushing rod 104 to pass through are formed in the upper stoppers, and square holes for the pressing block 1032 to pass through are formed in the lower stoppers. The moving block 102 and the fixing block 101 are placed inside the positioning block. The fixing block is fixed on one side, and the moving block 102 is movably arranged on the other side. Notches are formed on the side surfaces of the fixing block 101 and the moving block 102 facing each other. When the moving block 102 abuts against the fixing block 101, the two notches form a groove with an upward opening, and the workpiece 20 is fixed in the groove, and the end face of the workpiece 20 to be welded faces upward.

[0025] Refer to Figure 1-4 As shown in the figure, one end of the pressing rod 103 is hinged to the bottom plate 10. A cam 1031 is arranged at the end of the pressing rod 103 hinged to the bottom plate 10, and the cam 1031 abuts against the moving block 102. Specifically, a pressing block 1032 is installed at the end of the pressing rod 103. When the workpiece 20 needs to be positioned, the pressing rod 103 is rotated so that the pressing block 1032 presses the workpiece 20 in the groove. At the same time, the rotating pressing rod 103 drives the cam 1031 to rotate and push the moving block 102, that is, the workpiece 20 is pressed in two directions perpendicular to each other on the same plane. Further, the pressing rod 103 extends further outwards to be provided with a handle 106. Rotating the handle 106 drives the pressing rod 103 to rotate around the hinge point, making the operation more convenient and improving the positioning efficiency.

[0026] Refer to Figure 1-4 As shown in the figure, the pushing rod 104 is connected to the pressing rod 103, and the pushing rod 104 is movably placed between the fixing block 101 and the moving block 102.
