Technical Field

[0002] Steel pipe welding refers to the process of joining steel pipes together using welding technology. It is widely used in various engineering fields, such as oil and gas transportation, building structures, and machinery manufacturing. During welding, butt-jointing calibration equipment is typically used to secure and connect multiple steel pipes.

[0003] Currently available docking calibration equipment uses a relatively fixed docking angle when docking steel pipes, making it difficult to automatically adjust the docking angle based on the location of the welding point on the steel pipe. This significantly reduces the flexibility of the docking calibration equipment. Utility Model Content

There are multiple driving wheels 9, which are located on both sides of the output end of the dual-axis motor 8, used to drive multiple electric push rods 6 to rotate synchronously, improving the stability of the steel pipe rotation adjustment. The dual-axis motor 8 is fixedly connected to the inner wall of the connecting plate 4, and the output end of the dual-axis motor 8 is rotatably connected to the inner wall of the support plate 5. The inner wall of the drive wheel 9 is fixedly connected to the output end of the dual-axis motor 8. The transmission belt 10 meshes with the inner wall of the drive wheel 9. The inner wall of the driven wheel 11 is fixedly connected to the surface of the electric push rod 6, and the inner wall of the driven wheel 11 meshes with the transmission belt 10. This is used to drive the steel pipe to rotate, which facilitates automatic adjustment of the welding angle of the steel pipe. The top surface of the base plate 1 is provided with a clamping assembly, which consists of a limiting slide groove 12, a limiting slider 13, and a second clamping plate 14. The limiting slide groove 12 is opened through the top surface of the base plate 1. The limiting slider 13 is slidably connected to the inner wall of the limiting slide groove 12. The second clamping plate 14 is fixedly connected to the top surface of the limiting slider 13. This is used to clamp and fix the steel pipe, which improves the stability of the steel pipe during welding. The top surface of the base plate 1 is provided with a support mechanism, and the bottom surface of the base plate 1 is provided with a drive assembly.

[0021] Specifically, the support mechanism consists of a fixed frame 15 and an auxiliary wheel 16. The fixed frame 15 is fixedly connected to the top surface of the base plate 1, and the auxiliary wheel 16 is rotatably connected to the inner wall of the fixed frame 15.

[0022] Specifically, the drive assembly consists of a limiting ring 17, a servo motor 18, a bidirectional threaded rod 19, and a connecting frame 20. The limiting ring 17 is fixedly connected to the bottom surface of the base plate 1.

[0023] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0024] In use: First, place the main steel pipe on top of the base plate 1 and connect it with multiple auxiliary wheels 16. The rotation of the auxiliary wheels 16 assists in rotating the main steel pipe to adjust the welding position. Start the servo motor 18 to drive the bidirectional threaded rod 19 to rotate along the inner wall of the limiting ring 17. The bidirectional threaded rod 19 is threadedly connected to the connecting frame 20, which drives the limiting slider 13 to slide longitudinally along the inner wall of the limiting groove 12. The movement of the limiting slider 13 drives the second clamping plate 14 to move longitudinally to clamp and fix the main steel pipe. Start the electric push rod 6 to push the first clamping plate 7 to move and clamp and fix the auxiliary steel pipe. Start the dual-axis motor 8 to drive the drive wheel 9 and the transmission belt 10 to rotate. The engagement of the transmission belt 10 with the driven wheel 11 drives the electric push rod 6 and the first clamping plate 7 to rotate. The rotation of the first clamping plate 7 drives the auxiliary steel pipe to rotate to adjust the welding angle. Start the linear motor 3 to drive the electric push rod 6 to move laterally through the connecting plate 4 and the support plate 5. The movement of the electric push rod 6 drives the first clamping plate 7 and the auxiliary steel pipe to move laterally, thereby adjusting the welding position.

[0025] In summary, this steel pipe weld joint calibration equipment, through a support mechanism, assists in the rotation of the main steel pipe to adjust the welding position. Activating the drive assembly drives the clamping assembly to slide longitudinally, thus clamping and fixing the main steel pipe. Activating the electric push rod 6 pushes the first clamping plate 7 to move and clamp and fix the secondary steel pipe. Activating the adjustment mechanism and linear motor 3, through the connecting plate 4, support plate 5, electric push rod 6, and first clamping plate 7, drives the secondary steel pipe to move laterally and rotate simultaneously, thereby adjusting the welding position and welding angle of the secondary steel pipe. This achieves the goal of facilitating automatic adjustment of the welding angle and welding position of the steel pipe, avoiding the problem of significantly reduced flexibility in the use of existing docking calibration equipment due to its relatively fixed docking angle. This equipment addresses the problems mentioned in the background section.
