[0013] Compared with the prior art, the beneficial effects of the present utility model are:
[0014] For the welding device for pipeline welding, by providing the first arc-shaped slide rail and the second arc-shaped slide rail, the fixed seat is fixed to the top of the pipeline to be welded. The first driving motor drives the first displacement gear to rotate, thereby driving the first sliding block and the second arc-shaped slide rail to move. At the same time, the second driving motor drives the second sliding block and the electric push rod to move, so that the welding head moves to the bottom of the pipeline weld. The electric push rod pushes the welding head to fit with the weld for welding. Then the second driving motor reverses to drive the second sliding block and the electric push rod to move in the reverse direction, and the welding head welds the weld. When the second sliding block moves to the other end of the second arc-shaped slide rail, the first driving motor reverses, causing the second sliding block to move in the reverse direction, so that the welding head continues to weld until the welding is completed. Compared with manual welding, the working efficiency is higher.
[0015] For the welding device for pipeline welding, by providing the buffer assembly, when the electric push rod pushes the welding head to contact the pipeline, the telescopic rod pushes the piston plate to slide, thereby squeezing the buffer spring, ensuring that the welding head contacts the weld while buffering the impact force during contact. At the same time, as the welding head moves, the rollers roll, preventing damage to the welding head due to excessive friction. Description of the Drawings

Specific embodiments
[0021] 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.
[0022] Please refer to Figures 1 to 4, the present utility model provides a welding device for pipeline welding, including a fixed seat 1. A fixed bracket 2 is arranged on the top of the fixed seat 1. A connecting plate 3 is fixedly installed in the middle of the fixed bracket 2. A first arc-shaped slide rail 4 is fixedly installed at the bottom of the connecting plate 3. A first sliding block 6 is slidably connected to the front of the first arc-shaped slide rail 4. A first arc-shaped rack 5 is fixedly installed on the outer arc surface of the first arc-shaped slide rail 4. A second arc-shaped slide rail 9 is fixedly installed on the front of the first sliding block 6. A first driving motor 7 is fixedly installed on the top of the first sliding block 6. An output end of the first driving motor 7 is fixedly installed with a first displacement gear 8. The first displacement gear 8 meshes with the first arc-shaped rack 5. A second sliding block 11 is slidably connected to the front of the second arc-shaped slide rail 9. A second arc-shaped rack 10 is fixedly installed on the outer arc surface of the second arc-shaped slide rail 9. An electric push rod 14 is fixedly installed on the front of the second sliding block 11. A second driving motor 12 is fixedly installed on the top of the second sliding block 11. An output end of the second driving motor 12 is fixedly installed with a second displacement gear 13. The second displacement gear 13 meshes with the second arc-shaped rack 10. A welding head 16 is arranged at the movable end of the bottom of the electric push rod 14. By arranging the first arc-shaped slide rail 4 and the second arc-shaped slide rail 9, the fixed seat 1 is fixed to the top of the pipeline to be welded. The first driving motor 7 drives the first displacement gear 8 to rotate, thereby driving the first sliding block 6 and the second arc-shaped slide rail 9 to move. At the same time, the second driving motor 12 drives the second sliding block 11 and the electric push rod 14 to move, so that the welding head 16 moves to the bottom of the pipeline weld. The electric push rod 14 pushes the welding head 16 to fit with the weld for welding. Then the second driving motor 12 reverses to drive the second sliding block 11 and the electric push rod 14 to move in the reverse direction, and the welding head 16 welds the weld. When the second sliding block 11 moves to the other end of the second arc-shaped slide rail 9, the first driving motor 7 reverses, causing the second sliding block 11 to move in the reverse direction, so that the welding head 16 continues to weld until the welding is completed. Compared with manual welding, the working efficiency is higher.
[0023] The fixed seat 1, the first arc-shaped slide rail 4 and the second arc-shaped slide rail 9 are arranged concentrically, and limit flanges are fixedly installed at both ends of the first arc-shaped slide rail 4 and the second arc-shaped slide rail 9.
[0024] A buffer assembly 15 is arranged between the movable end of the electric push rod 14 and the welding head 16. A connecting frame 17 is fixedly installed on the outer peripheral surface of the top of the welding head 16. The connecting frame 17 is rotatably connected with rollers 18 located on both sides of the welding head 16.
[0025] The buffer assembly 15 includes a telescopic sleeve 1501 fixedly installed at the movable end of the electric push rod 14. A piston plate 1502 is slidably connected inside the telescopic sleeve 1501. A telescopic rod 1503 is fixedly installed at the bottom of the piston plate 1502. The bottom of the telescopic rod 1503 is fixedly installed with the top of the welding head 16. A buffer spring 1504 is arranged inside the telescopic sleeve 1501. The top of the buffer spring 1504 is fixedly installed with the inner top of the telescopic sleeve 1501. The bottom of the buffer spring 1504 is in tight contact with the top of the piston plate 1502. By providing the buffer assembly 15, when the electric push rod 14 pushes the welding head 16 to contact the pipeline, the telescopic rod 1503 pushes the piston plate 1502 to slide, thereby squeezing the buffer spring 1504, ensuring that while the welding head 16 contacts the weld seam, the impact force during contact is buffered. At the same time, as the welding head 16 moves, the roller 18 rolls, preventing damage to the welding head 16 due to excessive friction.
[0026] The central angles corresponding to the first arc-shaped slide rail 4 and the second arc-shaped slide rail 9 are the same, and the central angles corresponding to the first arc-shaped slide rail 4 and the second arc-shaped slide rail 9 are 180 degrees.
[0027] The two fixed seats 1 are respectively arranged at the rear side of the first arc-shaped slide rail 4 and the front side of the second arc-shaped slide rail 9.
[0028] Working principle:
[0029] Fix the fixed seat 1 to the top of the pipeline to be welded. The first driving motor 7 drives the first displacement gear 8 to rotate, thereby driving the first sliding block 6 and the second arc-shaped slide rail 9 to move. At the same time, the second driving motor 12 drives the second sliding block 11 and the electric push rod 14 to move, so that the welding head 16 moves to the bottom of the pipeline weld seam. The electric push rod 14 pushes the welding head 16 to fit with the weld seam for welding. Then the second driving motor 12 reverses to drive the second sliding block 11 and the electric push rod 14 to move in the reverse direction. The welding head 16 welds the weld seam. When the second sliding block 11 moves to the other end of the second arc-shaped slide rail 9, the first driving motor 7 reverses, causing the second sliding block 11 to move in the reverse direction, so that the welding head 16 continues to weld until the welding is completed. And when the electric push rod 14 pushes the welding head 16 to contact the pipeline, the telescopic rod 1503 pushes the piston plate 1502 to slide, thereby squeezing the buffer spring 1504, ensuring that while the welding head 16 contacts the weld seam, the impact force during contact is buffered. At the same time, as the welding head 16 moves, the roller 18 rolls, preventing damage to the welding head 16 due to excessive friction.
