[0037] A welding mechanism 12 is provided on the main body 10, and the welding mechanism 12 is located on one side of the positioning plate 41. The welding mechanism 12 is specifically provided with two, one for preheating the welded parts and the other for welding processing of the welded parts. The welding mechanism 12 includes a welding assembly, and the welding assembly includes a welding gun 16, a connecting block 18 connected to the welding gun 16, a slide 17 slidably connected to the connecting block 18, a base plate connected to the slide 17, a moving block 22 connected to the base plate, a cylinder 19 cooperating with the moving block 22, a matching seat 20 connected to the cylinder 19, and a mounting seat connected to the matching seat 20.

A slide rail 25 is installed on the base 24, and a slider 23 is installed on the slide rail 25. The slider 23 moves along the slide rail 25 to improve the stability of the movement. The slider 23 connects the rotating member 27 and the mounting seat. When the screw 26 rotates, the moving block 22 moves up and down along the slide rail 25, and at the same time drives the welding mechanism 12 to move synchronously. The forward and reverse rotation of the servo motor 28 drives the welding mechanism 12 to swing slightly up and down, so that the flame can evenly heat the welding point, thereby improving the welding effect.

[0041] A cooling assembly is also provided on the main body 10. The cooling assembly can adopt components in the prior art, and water cooling or other components with the same effect can be used to cool the welded parts.

The drainage groove is provided with drainage holes for centralized treatment of the cooling medium. The setting of the water baffle 34 prevents the medium from splashing out of the welding station when the welded parts are cooled after completion, affecting the work of subsequent components.

[0042] The working principle of this utility model is as follows:

[0043] First, according to the actual situation of welding, the welding position of the welding mechanism 12 is adjusted through the controller 13, and the welding assembly is installed on the positioning block 37. The positioning piece 39 cooperates with the positioning block 37 to position and install the welding assembly. The controller 13 controls the rotating mechanism 11 to rotate, and the rotating mechanism 11 drives the work station plate to rotate so that the work station plate is located at the preheated welding assembly for preheating treatment. After the preheating is completed, the controller 13 controls the rotating mechanism 11 to rotate and drives the work station plate to move to the welding position. The welding position of the welding assembly is welded by the cooperation of the welding assembly, the swing assembly 15 and the adjustment assembly 32. After completion, the rotating work station plate cools the welded assembly through the cooling assembly. After cooling is completed, the material is unloaded and the above operations are repeated for welding.

[0044] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto.
