[0024] The structure provided by the utility model is explained and illustrated in detail below in conjunction with the accompanying drawings of the specification.

[0025] refer to Figures 1 to 6 As shown, the present embodiment specifically discloses an angle positioning welding tool, including a base plate 1 for placing a workpiece 100 to be welded, at least two slide bars 2 are penetrated on one side of the base plate 1, the base plate 1 can slide up and down along the slide bar 2 and be fixed by a locking member 3, in the present embodiment, the locking member 3 is a top screw, which is convenient for adjustment, in some other embodiments, the locking member 3 can also be a structure such as a clamp, which can limit the base plate 1 from sliding on the slide bar 2 when clamped, and the base plate 1 can slide up and down on the slide bar 2 after loosening, and the top of the slide bar 2 is commonly connected with a scale plate 4 for measuring angles, it can be understood that an angle scale is engraved on the scale plate 4, and a positioning pin 5 is connected to the scale plate 4 through a fixing member 6, the side of the positioning pin 5 is against one of the flanges of the workpiece 100 to be welded, and loosening the fixing member 6 can adjust the indication angle of the positioning pin 5 on the scale plate 4.

[0026] In this embodiment, the workpiece 100 to be welded is a transition joint of a generator set, which includes a joint pipe 110, a first flange 120 connected to one end of the joint pipe 110, and a second flange 130 connected to the other end of the joint pipe 110. There is a certain angle difference between the first flange 120 and the second flange 130. When in use, one of the flanges can be welded and fixed to the joint pipe 110 first, and then placed on the base plate 1, and then the tip of the locating pin 5 is pointed to the required angle according to actual needs, and then the fixing member 6 is tightened to fix the pointing angle of the locating pin 5. In this embodiment, the fixing member 6 is a knurled bolt for easy screwing. In some other embodiments, the fixing member 6 can also be a hexagonal bolt, a round head bolt, a cross-slot bolt, etc. After adjusting the pointing angle of the locating pin 5, the other unconnected flange can be pressed against one side of the locating pin 5, and then welding can be performed. The transition joints of the generator set can be welded in batches, and the overall specific welding efficiency is high, which is conducive to realizing the advantages of industrial processing, and the consistency of the workpiece after welding is good.

[0027] Continue to combine Figure 5 As shown, the positioning pin 5 includes an indicator plate 51 and a support plate 52 vertically connected to the indicator plate 51. A triangular indicator portion 53 is formed at one end of the indicator plate 51. The indicator portion 53 indicates on the angle scale line of the scale plate 4. The support plate 52 abuts against the side wall of one of the flanges of the workpiece 100 to be welded. The indicator portion 53 is triangular, and its tip indicates the angle more accurately. The support plate 52 vertically connected is arranged on one side of the indicator plate 51 to facilitate the positioning of the flange, increase the contact area between the positioning pin 5 and the flange, and increase the stability of the flange during welding.
