[0031] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0032] Example 1

[0033] refer to Figures 1 to 3This embodiment discloses an automated steel bar welding device, including a protective box 1, a rotating mechanism 3 and an air cooling device 4. Through holes 105 for the steel bars to be welded are provided on both sides of the protective box 1. Clamping mechanisms 2 are also provided on both sides of the protective box 1. The two sections of steel bars to be welded pass through the through holes 105 on both sides respectively and are fixed by the clamping mechanism 2 so that the parts of the steel bars to be welded are placed in the protective box 1. The clamping mechanism 2 can be arranged on both sides inside or outside the protective box 1, preferably inside the protective box 1 to make the structure more compact. The rotating mechanism 3 is arranged in the protective box 1, and a welding head 7 is connected to the rotating mechanism 3. The rotating mechanism 3 can drive the welding head 7 to rotate around the axis of the steel bars to be welded. An air cooling device 4 is also provided at the same time. The air cooling device 4 is connected to the protective box 1 and is used to cool the air in the protective box 1.

[0034] The automated steel bar welding device of this embodiment can play a role in preventing wind, sand and fire by placing the welded steel bars in a protective box 1 for welding; by arranging a rotating mechanism 3 in the protective box 1 and connecting the welding head 7 to the rotating mechanism 3, the position of the welding head 7 can be automatically adjusted in the box, thereby welding the entire circumference of the steel bar and improving the welding efficiency; at the same time, the air in the box is cooled by the air cooling device 4, thereby improving the welding quality.
