DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.
[0027] Please refer to Figure 1 to Figure 3 The present embodiment provides a valve body welding tool, comprising a tooling table 1, a valve body bracket 3, a flange bracket 5 and a rotation and limit assembly; the tooling table 1 is provided with a flange positioning groove 2; the rotation and limit assembly is installed on the tooling table 1, and is provided with a first rotation axis 9 and a second rotation axis 11 located directly below the first rotation axis 9, and the first rotation axis 9 is parallel to the second rotation axis 11; the valve body bracket 3 is detachably installed on the second rotation axis 11 and is located directly above the flange positioning groove 2; the flange bracket 5 is detachably installed on the first rotation axis 9 and is located directly above the valve body bracket 3.
[0028] The method of using the valve body welding tooling described in this embodiment is as follows:
[0029] 1) Place the lower flange in the flange positioning groove 2, place the upper flange in the flange support 5, place the valve body vertically between the lower flange and the upper flange, and fix the valve body with the locking screws on the valve body bracket 3.
[0030] Note: The assembly clearance between the flange and the valve body before welding is generally 1 to 3 mm. In special circumstances, in order to ensure the welding quality and welding operability, the clearance shall not exceed 5 mm at most; therefore, when processing this tooling, in order to flexibly adjust the clearance according to the actual production conditions, the bottom depth of the flange positioning groove 2 can be processed to 5 mm, and then equipped with a number of 0.5 mm and 1 mm thick gaskets, and the assembly clearance between the flange and the valve body can be flexibly adjusted by adding or subtracting gaskets. That is, if there is a large gap between the upper and lower ends of the valve body and the lower flange and the upper flange, gaskets can be placed in the flange positioning groove 2, and the lower flange and the valve body can be slightly raised together, so that the valve body and the flange are in good contact, and then the valve body can be fixed by the valve body bracket 3.
[0031] 2) Unlock the rotation and limit assembly. Under the rotation of the first rotation shaft 9 and the second rotation shaft 11, the flange support 5 and the valve body bracket 3 can both rotate, and then the valve body and the upper flange are adjusted to be horizontal, so that the valve body and the flange are in a weldable posture, and then the rotation and limit assembly is used to keep the flange support 5 and the valve body bracket 3 in the current posture;
[0032] 3) Weld the upper flange to the upper end of the valve body and the lower flange to the lower end of the valve body;
[0033] 4) Remove the flange support 5 and the valve body bracket 3, and take out the entire welded valve body.

The conical pin 15 holes of the first rotating shaft 9 and the second rotating shaft 11 are precisely matched with the conical pin 15 of the anti-rotation structure through the adjusting bolt 10 to achieve locking and unlocking operations. The lubricating oil film reduces friction, ensures smooth adjustment, improves operation convenience and assembly accuracy, and significantly improves the stability and efficiency of welding operations.
[0037] In this embodiment, the first rotating shaft 9 is radially equipped with a locking screw 13, and the second rotating shaft 11 is radially equipped with a locking screw 2 12. The locking screw 13 and the locking screw 2 12 are used to respectively assist in tightening the two tapered pins 15. The additional locking measures improve the stability of the assembly process, reduce the risk of loosening and displacement, and further improve the welding accuracy and safety.
[0038] In this embodiment, the flange support 5 is provided with a through hole having a diameter larger than the diameter of the flange to be welded, and the through hole can be detachably mounted with the annular flange support plate 6. The upper flange can be supported by the annular flange support plate 6, and after the annular flange support plate 6 is removed and the upper flange is disassembled from the first rotating shaft 9, the flange support 5 can be removed from above, and the upper flange passes through the through hole during the process.
[0039] In this embodiment, the flange support 5 is detachably mounted on the first rotating shaft 9 via a first connecting assembly 8. The first connecting assembly 8 includes two connecting plates respectively welded to the first rotating shaft 9 and the flange support 5, and fixing screws connecting the two connecting plates.
