[0002] Welding is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Modern welding utilizes a variety of energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance oil and natural gas transportation, agricultural irrigation, hydraulic engineering, and various industrial installations. Straight pipe welding is one of the most common techniques in pipe installation to extend pipe length.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1, such as Figure 1-2 As shown, this utility model provides a technical solution: a clamping fixture for robotic pipe welding, including a mounting frame 1, a movable frame 5, and a pipe body 14. A rotating shaft 4 is mounted inside the mounting frame 1 via bearings, and the movable frame 5 is mounted on the inner side wall of the rotating shaft 4. Longitudinal slide rails 6 are mounted on both side walls of the movable frame 5, and a clamping frame 7 is arranged inside the longitudinal slide rails 6 and the movable frame 5. The pipe body 14 is positioned above the clamping frame 7. A transverse slide rail 8 is mounted at the bottom of the clamping frame 7, and a clamping bracket 11 that contacts the pipe body 14 is arranged inside the transverse slide rail 8. A pressure sensor 12 that fits against the outer wall of the pipe body 14 is arranged at the top of the clamping bracket 11. The clamping frame 7 contains... An adjustment mechanism for adjusting the spacing between clamping frames 11 includes a second motor 9 and a positive and negative lead screw 10. The second motor 9 is installed on the inner wall of the clamping frame 7, and the output end of the second motor 9 is connected to the positive and negative lead screw 10 through the clamping frame 11 via a coupling. The outer wall of the positive and negative lead screw 10 meshes with the inner wall of the clamping frame 11. By starting the second motor 9, the positive and negative lead screw 10 is driven to rotate, thereby the positive and negative lead screw 10 drives the clamping frame 11 to clamp and fix the pipe body 14, so that the pressure sensor 12 comes into contact with the pipe body 14. Then, the pressure sensor 12 feeds back the information to the microcontroller 16, and the microcontroller 16 can turn off the second motor 9 to clamp and fix different pipe bodies 14.

[0019] Example 2, as Figure 1-3As shown, this utility model provides a technical solution: a clamping fixture for robotic pipe welding, including a cylinder 15 on one side of a clamping frame 7, with the output end of the cylinder 15 connected to the other side of the clamping frame 7, a caster wheel 2 at the bottom of a mounting frame 1, a first motor 3 on one side of the mounting frame 1, with the output end of the first motor 3 connected to one side of a rotating shaft 4 via a coupling, and a microcontroller 16 at the top of the first motor 3. A threaded groove is provided inside the clamping frame 11, and a positioning screw 13 penetrating the pipe body 14 is provided inside the threaded groove. After clamping and fixing two sets of pipe bodies 14, the cylinder 15 can be activated to drive the clamping frame 7 to slide within the longitudinal slide rail 6, thereby causing the clamping frame 7 to move one set of pipe bodies 14 towards the other set of pipe bodies 14, completing automatic fitting. Finally, the positioning screw 13 can be rotated and inserted into the pipe body 14, thereby fixing and clamping the pipe body 14.

[0020] Working principle: First, connect the external power supply. The operator can place the pipe body 14 above the clamping frame 7. Then, start the second motor 9 to drive the positive and negative screws 10 to rotate. The positive and negative screws 10 drive the clamping frame 11 to clamp and fix the pipe body 14. After the pressure sensor 12 contacts the pipe body 14, the pressure sensor 12 feeds the information back to the microcontroller 16. The microcontroller 16 can then turn off the second motor 9. After clamping and fixing two sets of pipe bodies 14, the cylinder 15 can be started to drive the clamping frame 7 to slide in the longitudinal slide rail 6. The clamping frame 7 then drives one set of pipe bodies 14 to fit into another set of pipe bodies 14, completing the automatic fitting. Finally, the positioning screw 13 can be rotated and inserted into the pipe body 14 to fix and clamp the pipe body 14. The operator can start the first motor 3 to drive the rotating shaft 4 to rotate. The rotating shaft 4 then drives the moving frame 5 to flip, making it easy to adjust the angle of the pipe body 14.
