[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1 - 6 , the present utility model provides the following technical solutions.

[0032] Embodiment 1: To solve the problem in the prior art that it is inconvenient to stably clamp the pipeline to be welded and the pipeline is prone to shaking during the welding process. Therefore, in this embodiment, through the following technical solutions, an electric welding machine for welding an oil pipeline is provided with a base 1, a movable column 4, a support clamp 10, a fixed plate 13, a movable bracket 14, a spring 15 and a positioning plate 16. The clamping mechanism 9 includes a support clamp 10 fixedly connected to the upper end of the movable column 4, a fixed clamp 11 hinged to the upper end of the support clamp 10, and a movable roller 12 rotatably connected to the inner sides of the support clamp 10 and the fixed clamp 11. A fixed plate 13 is fixedly connected to the front side of the fixed clamp 11, and a movable bracket 14 is slidably connected to the middle of the fixed plate 13. A spring 15 is arranged between the movable bracket 14 and the fixed plate 13, and a positioning plate 16 is fixedly connected to the front end of the movable bracket 14. Moreover, the positioning plate 16 is arranged in a fitting manner with the front side of the upper end of the support clamp 10, as Figure 1 , Figure 4 , Figure 5 and Figure 6 shown. First, place the oil pipeline to be welded in the middle of the support clamp 10, then pull the movable bracket 14. The movable bracket 14 slides between the fixed plate 13. At this time, the movable bracket 14 squeezes the spring 15, causing the spring 15 to undergo elastic deformation. The movable bracket 14 drives the positioning plate 16 to move away from the fixed clamp 11. Then, turn the fixed clamp 11 downward. The fixed clamp 11 rotates with the support clamp 10. The fixed clamp 11 is clamped on the upper end of the support clamp 10. The oil pipeline is clamped and fixed by the fixed clamp 11 and the support clamp 10 to improve the stability of the oil pipeline during the welding process. Then, directly release the movable bracket 14. At this time, the spring 15 restores its elastic deformation, driving the movable bracket 14 to slide between the fixed plate 13. The movable bracket 14 drives the positioning plate 16 to move, so that the positioning plate 16 is arranged in a fitting manner with the support clamp 10, thereby facilitating the limitation between the support clamp 10 and the fixed clamp 11.

[0033] Embodiment 2: For the existing electric welding machine for oil pipeline welding, the stability of the pipeline during transportation and support is not good. Therefore, by setting a servo motor 2, a lead screw 3, a movable column 4, a movable block 5, side plates 6, a connecting frame 7 and a connecting roller 8, the movable columns 4 are respectively threadedly connected to the left and right ends of the lead screw 3. The movable columns 4 at the left and right ends move towards each other at the upper end of the base 1. The thread directions at the left and right ends of the lead screw 3 are opposite. The connecting roller 8 is rotatably connected to the middle of the connecting frame 7. The output end of the servo motor 2 is fixedly connected to the lead screw 3, and the servo motor 2 drives the lead screw 3 to rotate at the upper end of the base 1. Connecting frames 7 are fixedly connected to both the left and right sides at the upper end of the base 1. Movable blocks 5 are fixedly connected to both the front and rear ends of the movable column 4, and a left-right sliding structure is formed between the movable block 5 and the side plate 6. The side plates 6 are respectively fixedly connected to the front and rear sides at the upper end of the base 1. As Figure 1 , Figure 2 and Figure 3 shown, after the oil pipeline is clamped, the oil pipeline is in a fitting arrangement with the movable roller 12. At the same time, the oil pipeline is fittingly arranged on the upper end of the connecting roller 8. Start the servo motor 2. The servo motor 2 drives the lead screw 3 to rotate at the upper end of the base 1, so that the lead screw 3 drives the movable column 4 to move at the upper end of the base 1. Combining with the sliding between the movable block 5 and the side plate 6, the stability of the movable column 4 moving at the upper end of the base 1 is improved. The movable column 4 drives the oil pipelines on both sides to move towards the side close to the vertical central axis of the base 1. At the same time, during the movement, the oil pipeline drives the connecting roller 8 to rotate on the upper end of the connecting frame 7, so as to be able to assist in supporting the oil pipeline, and make the oil pipelines on the left and right sides be in a fitting arrangement with each other.

[0034] Embodiment 3: For the existing electric welding machine for oil pipeline welding, it is not convenient to drive the pipeline to rotate during welding to weld each position at the edge of the pipeline. Therefore, by setting movable rollers 12, the movable rollers 12 are arranged at equal angles respectively inside the support clamp 10 and the fixed clamp 11. As Figure 1 and Figure 4 shown, when the oil pipeline reaches the corresponding position, the operator welds the joint of the oil pipeline through the electric welding machine. At the same time, during the welding operation, by slowly rotating the oil pipeline, the oil pipeline drives the movable rollers 12 to rotate respectively in the movable roller 12 and the fixed clamp 11, so that the oil pipeline rotates more smoothly, and thus it is convenient to perform better welding processing on the edge of the joint of the oil pipeline.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
