[0027] Please refer to Figure 1 and Figure 2 As shown, a three-way flange pipe welding tool comprises:

[0028] A workbench 1 is used to carry a workpiece to be processed, and a flange end of a main pipe section 2 of the workpiece to be processed is placed on the workbench 1;

[0029] A top positioning mechanism 3 is constructed on the top surface of the workbench 1 and is used to position the other flange end of the main pipe section 2 of the workpiece to be processed;

[0030] The main pipe section 2 of the workpiece to be processed is clamped between the workbench 1 and the top positioning mechanism 3;

[0031] The branch pipe positioning mechanism 4 is constructed on the top surface of the workbench 1, and is constructed with a bearing plate 42 set at an angle to the top surface of the workbench 1, the bearing surface of the bearing plate 42 faces between the top positioning mechanism 3 and the workbench 1, and the bearing plate 42 is used to receive the flange end of the branch pipe section of the workpiece to be processed.

[0032] In this way, when in use, the flanges of the main pipe are positioned and installed on the top surface of the workbench 1 and the bottom surface of the top positioning mechanism 3, and then the main pipe is placed between the upper and lower flanges, so as to perform stable welding. After the main pipe is installed, the flanges of the branch pipes to be connected are placed on the bearing plate 42 and fixed to the bearing plate 42, so as to use the angle of the bearing plate 42 to fix the installation angle of the branch pipes, and then complete the welding positioning of the branch pipes and the main pipes. This effectively increases the dimensional stability of the three-way flange pipe during the welding process, while avoiding the displacement deformation between the flange and the pipe body during the welding process, and avoiding the displacement deformation between the branch pipe and the main pipe, thereby improving the accuracy of the welding operation.

[0033] Furthermore, the top surface of the workbench 1 is constructed with a first main pipe positioning mechanism 6, which is arranged just below the top connection end of the top positioning mechanism 3, and is composed of a number of positioning bolts 7 corresponding to the through holes of the flange.

[0034] In this way, the lower flange of the main pipe is locked and positioned by using the positioning bolts 7 on the first main pipe positioning mechanism 6 .

[0035] At the same time, the top positioning mechanism 3 includes a first support plate 31 installed on the top surface of the workbench 1, the first support plate 31 is vertically arranged, and a horizontal abutment plate 32 is installed on the top side of the first support plate 31, and the bottom surface of the horizontal abutment plate 32 is used to abut the top flange of the main pipe section 2.

[0036] Specifically, the bottom surface of the horizontal abutment plate 32 is constructed with a second main pipe positioning mechanism 8, which includes a bolt positioning portion 81 and a horizontal gasket 82. The bolt positioning portion 81 is composed of a plurality of positioning bolts 7 that match the through holes of the top flange of the main pipe section 2. The horizontal gasket 82 is provided with bolt through holes and is fitted with the bottom surface of the horizontal abutment plate 32 through the positioning bolts 7.

[0037] In this way, the bolt positioning part 81 in the second main pipe positioning mechanism 8 is used to lock and fix the top flange of the main pipe, and the horizontal gasket 82 is used to connect the top of the main pipe with the horizontal abutment plate 32. After the welding is completed, the positioning bolt 7 is taken out and the horizontal gasket 82 is taken out, so that there is a gap between the top of the main pipe and the horizontal abutment plate 32, which facilitates the removal of the main pipe from between the workbench 1 and the top positioning mechanism 3, avoiding a lot of wear between the top of the main pipe and the horizontal abutment plate 32.

[0038] Furthermore, in order to improve the stability of the first support plate 31 during the positioning process, a reinforcing rib plate 9 is installed on the side of the first support plate 31 .

[0039] Furthermore, as for the branch pipe positioning mechanism 4, the branch pipe positioning mechanism 4 includes a second support plate 41 installed on the top surface of the workbench 1, the second support plate 41 is vertically arranged, the top side of the second support plate 41 is set as an inclined structure, the top side of the second support plate 41 is installed with the bearing plate 42 that is angled with the horizontal plane, and the bearing plate 42 is configured with a branch pipe fixing mechanism 10 on one side facing between the workbench 1 and the top positioning mechanism 3;

[0040] The branch pipe fixing mechanism 10 includes a branch pipe positioning portion 101 and an inclined gasket 102 . The branch pipe positioning portion 101 is composed of a plurality of positioning bolts 7 matching the through holes of the branch pipe flange portion. The inclined gasket 102 is provided with bolt through holes and is fitted with the bearing plate 42 through the positioning bolts 7 .

[0041] In this way, the flange of the branch pipe is locked and fixed by the bolts of the branch pipe positioning part 101. Similar to the above, the inclined gasket 102 is used to connect the branch pipe flange part and the bearing plate 42. After welding is completed, the inclined gasket 102 is removed to avoid a large amount of wear on the flange of the branch pipe and the bearing plate 42.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
