In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, also not within the protection scope of the utility model.

[0055] Please refer to the drawings in the description Figures 1-8 The utility model provides a kind of automatic butt welding device for building steel bar:

[0056] Bottom support and mounting frame:

[0057] The bottom support 1 is designed as a sturdy platform to support the entire device operation. Three mounting frames 2 are distributed at the center and both ends of the bottom support 1, ensuring that the reinforcement can be stably sent from both sides to the center welding position while maintaining the symmetry and balance of the overall structure.

[0058] Reinforcement conveying mechanism:

[0059] Each reinforcement conveying mechanism 3 is designed to improve conveying efficiency and accuracy:

[0060] Feeding tooth roller 31: It has high load capacity to accommodate steel bars of different diameters, ensuring smooth advancement of the steel bar during conveying.

[0061] Clamping tooth roller 32: It is designed in pairs with the feeding tooth roller 31 above and below, capable of clamping the steel bar between the clamping tooth roller 32 and the feeding tooth roller 31, ensuring the precise position of the steel bar during conveying to the welding point.

[0062] Drive motor 33: It can operate continuously to drive the feeding tooth roller 31 to rotate, thereby ensuring the power of the steel bar feeding.

[0063] Pressing assembly 34: Its design ensures that the clamping tooth roller 32 applies uniform pressure during steel bar transmission, avoiding displacement or rotation of the steel bar during clamping.

[0064] Positioning and welding mechanism:

[0065] The key to the design of the center welding mechanism 4 is to improve welding accuracy and efficiency:

[0066] Synchronous cylinder 41: It is used to accurately control the movement of the end positioning and clamping block 42, and the synchronous operation of the cylinder ensures that the end positioning and clamping block 42 is stably clamped on the two steel bars to be welded, thereby improving the welding quality.

[0067] End positioning and clamping block 42: It has specially designed grooves that not only help fix the steel bar but also provide a welding space for the welding assembly 43 at the center position, ensuring stable positioning.

[0068] Welding assembly 43:

[0069] Fixed ring 431 and driven tooth ring 432: This design allows the driven tooth ring 432 to rotate stably and accurately during welding, and the welding gun head 433 mounted on the driven tooth ring 432 can uniformly weld around the steel bar, ensuring the uniformity and strength of the welding.

[0070] Drive gear 434 and reduction motor 435: The reduction motor 435 provides the necessary torque, which is transmitted through the precise meshing of the drive gear 434 and the driven tooth ring 432, ensuring smooth welding process. This design also helps to reduce mechanical wear and noise.

[0071] Steel bar guide pipe 5:

[0072] To ensure that the steel bars sent by the two steel bar conveying mechanisms 3 can be smoothly and accurately guided to the positioning and welding mechanism 4.

[0073] Working principle

[0074] Steel bar loading and conveying:

[0075] Two steel bars are conveyed to the center through the two steel bar conveying mechanisms 3. The feeding tooth roller 31 pushes the steel bars forward, and the clamping tooth roller 32 clamps the steel bars to ensure that they do not rotate or displace during the conveying process.

[0076] Steel bar positioning and preparation for welding:

[0077] The steel bars are conveyed to the center welding mechanism 4, and after the two steel bar ends are aligned, the end positioning and clamping block 42 controlled by the synchronous cylinder 41 tightly clamps the two steel bar ends.

[0078] Welding process:

[0079] The driven tooth ring 432 in the welding assembly 43 starts to rotate through the driving of the reduction motor 435 and the drive gear 434, ensuring smooth progress of the welding process.

[0080] The welding gun head 433 rotates stably with the driven tooth ring 432, performing annular welding around the steel bars, ensuring the uniformity and strength of the welding.
