[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions 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. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] Reference Figure 1 and Figure 3 The top of the protective plate 2 is fixedly connected to the workbench 1, and an observation window 3 is arranged inside the protective plate 2. The observation window 3 is a kind of shading lens, which protects the eyes when observing welding. Threaded columns 4 are arranged on the top of the workbench 1 and on both sides of the protective plate 2. A tightening ring 5 is threadedly connected to the threaded column 4. By rotating the tightening ring 5 and the threaded connection between it and the threaded column 4, the position of the tightening ring 5 on the threaded column 4 can be adjusted, so that the welding tool can be suitable for head assemblies of different lengths. The two groups of threaded columns 4 and the tightening ring 5 are centrally symmetrically arranged on the workbench 1. The welding position remains unchanged when rotating 180°. A positioning rod 6 is also fixedly connected to the workbench 1, and a positioning ring 7 is fixedly connected to the top of the positioning rod 6. A locking mechanism 8 is arranged on one side of the protective plate 2 and above the positioning ring 7, which can well position the head assembly and facilitate subsequent welding.

[0027] Reference Figure 1 and Figure 2 A column 9 is fixedly connected to the bottom center of the workbench 1, and the bottom end of the column 9 is rotatably connected to the base 10. A driven gear 11 is fixedly connected to the column 9, and a driving motor 12 is fixedly connected to the base 10. A driving gear 13 is fixedly connected to the output shaft of the driving motor 12. The driving gear 13 is meshed with the driven gear 11. The driving motor 12 can control the stable rotation of the workbench 1, so that after welding is completed, the welded head assembly can be quickly removed, thereby increasing the welding efficiency.

[0028] Reference Figure 4 The locking mechanism 8 includes two sets of fixing rings 81, and a connecting rod 82 is fixedly connected between the two sets of fixing rings 81. Bolts 83 are threadedly connected to the interior of the two sets of fixing rings 81. The bottom ends of the two sets of bolts 83 are provided with tightening blocks 84. By rotating the bolts 83, the head assembly can be well tightened, which is convenient for subsequent welding. At the same time, the welded head assembly can be easily removed so that it can be installed and welded for the next head assembly. One side of a set of fixing rings 81 is fixedly connected with a positioning block 85, and one side of the positioning block 85 is fixedly connected to the protective plate 2. The two sets of fixing rings 81 are respectively located above the two sets of positioning rings 7, and the material of the tightening block 84 is nitrile rubber.

[0029] The implementation principle of this embodiment is as follows: when in use, the tooling is placed on one side of the welding robot, and then the head assembly is installed on one side so that the bottom of the head assembly is located on the threaded column 4, and one end is pressed against the pressing ring 5. By rotating the pressing ring 5, it can be suitable for head assemblies of different lengths. Then part of the head assembly is located on the positioning ring 7, and the pressing block 84 can be pressed against the head assembly by rotating the bolt 83. After the head assembly on one side is installed, the drive motor 12 is started, and the output shaft of the drive motor 12 drives the active gear 13 to rotate, thereby driving the driven gear 11 to rotate, so that the column 9 drives the workbench 1 to rotate, and the workbench 1 rotates 180°, so that the installed head assembly is located at the welding position of the welding robot, and another head assembly that needs to be welded is installed on the other side of the protective plate 2, which can increase the welding efficiency of the head assembly.
