A positioning base 6 is fixedly installed on the outer wall of the rotating block 3. A guide rod 7 is fixedly connected to the top of the positioning base 6. One end of the laser welding device body 4 is movably installed on the outer wall of the guide rod 7.

[0027] The specific configuration and function of this embodiment are described in detail below. The specific shape of the rotating block 3 is a hexagon, and three positioning bases 6 are arranged at equal intervals on its edge. The guide rod 7 is installed on the top of the positioning base 6 to determine the specific position of the laser welding device body 4. When in use, the object is on the fixed component 5, and the laser welding device body 4 surrounds the fixed component 5.

A positioning groove 59 is provided on the surface of the positioning block 51 to determine the rotation plane of the rotating block 3 to avoid the problem of misalignment. When it is necessary to adjust the position or direction of the laser welding device body 4, the reduction motor 56 drives the docking gear 57 to push the internal gear ring 8 on the side of the rotating block 3, thereby driving the rotating block 3 to rotate, thereby achieving the purpose of adjusting the position of each laser welding device body 4.

[0029] Embodiment 2
