[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0033] Reference Figure 1 , Figure 2 , Figure 4 This utility model provides an embodiment of a quick-installation fixture for pipe welding, comprising a base plate 1, which is the foundation of the entire fixture. A disc 2 is fixedly connected to the top of the base plate 1, serving as the rotational foundation of the entire fixture structure. The disc is a circular planar structure made of aluminum alloy, providing rotational support. A pushing assembly is fixedly connected to the front of the disc 2, comprising a circular support base 3 and a cylinder 4. The rear of the circular support base 3 is fixedly connected to the front of the disc 2, supporting the cylinder 4. The right side of the cylinder 4 is fixedly connected to the left side of the circular support base 3, providing pushing force. The cylinder 4 generates linear pushing force through compressed gas, thereby driving a rotating plate 5 to slide. The pushing assembly is slidably connected to the rotating plate 5, which slides downwards driven by the cylinder 4. The inner side of the rotating plate 5 is rotatably connected to... There is a sliding block 6. The rotating plate 5 slides and drives the sliding block 6 to slide inside the circular plate 2. The sliding block 6 is rotatably connected to a rotating shaft 7. The rotating shaft 7 is used to fix and limit the sliding range of the rotating plate 5 outside the sliding block 6. The front side of the sliding block 6 is fixedly connected to a sliding assembly, which includes a slider 8 and a groove block 9. The rear side of the slider 8 is fixedly connected to the front side of the disk 2. The slider 8 slides inside the groove block 9 under the drive of the sliding block 6. The outside of the groove block 9 is slidably connected to the inside of the slider 8, so that the slider 8 can slide in the groove block 9.

[0034] The sliding assembly is rotatably connected to a rotating wheel 10. The sliding wheel is used to affect the rotation of the pipe 16 to be welded while it is fixed. A connecting rotating rod 11 is rotatably connected to the right side of the rotating plate 15. The connecting rotating rod 11 can transmit the movement of the bottom component to the rotating plate 22. The components connected to the upper and lower sides of the connecting rotating rod 11 have the same structure. The connecting rotating rod 11 is used to transmit the power of the cylinder 4 to the upper part and can drive the three rotating wheels 10 to slide inward. A rotating plate 22 is rotatably connected to the connecting rotating rod 11 on the side away from the rotating plate 15. The rotating plate 22 is mounted on the upper front side of the disc 2 in the same way as the rotating plate 15. A connecting rotating rod 13 is rotatably connected to one side of the connecting rotating rod 11. Connecting rotating rod 13 transmits power to the follower plate 14 in the same way as connecting rotating rod 11. The bottom of connecting rotating rod 13 is rotatably connected to the follower plate 14, which transmits motion to sliding block 15, causing the rotating wheel 10 connected to its front to slide. Sliding block 15 is rotatably connected to the inner side of the follower plate 14. Sliding block 15 rotates as needed and slides in coordination with the follower plate 14 for adjustment. The inside of the disc 2 is rotatably connected to the pipe to be welded 16. The pipe to be welded 16 is the core component of the clamps. The purpose of the clamps is to ensure the correct position and angle of the pipe during the welding process. The pipe is rotated, clamped, and fixed to ensure precise welding.

[0035] Reference Figure 2 , Figure 3 , Figure 5 A support plate 17 is fixedly connected to the top of the base plate 1 to support the drive assembly. The drive assembly, including a motor 18 and an output shaft 19, is fixedly connected to the rear side of the support plate 17. The front side of the motor 18 is fixedly connected to the rear side of the support plate 17, and the output shaft 19 provides power. The rear side of the output shaft 19 is fixedly connected to the front side of the motor 18. The output shaft 19 transmits the power of the motor 18 to the semicircular block 20 and the intermittent drive plate 21, thereby realizing rotation and propulsion. The drive assembly is rotatably connected to the semicircular block 20. The function of the semicircular block 20 is to drive the motor 18 through the intermittent drive plate 21. The clamping block 22, which is transmitted to the intermittent turntable 23, clamps and rotates the pipe 16 to be welded. The rear side of the semicircular block 20 is rotatably connected to the intermittent drive plate 21. The intermittent drive plate 21 has a plate-shaped component with a protruding cylinder on its front side, which is used to periodically slide in the groove opened in the intermittent turntable 23 to push the intermittent turntable 23. The outside of the pipe 16 to be welded is rotatably connected to the clamping block 22. While the clamping block 22 is fixed, it drives the pipe 16 to be welded to rotate. The rear side of the clamping block 22 is fixedly connected to the intermittent turntable 23, which is used to adjust the pipe 16 to be welded to the appropriate position through intermittent rotation.

[0036] Reference Figure 1 , Figure 3 , Figure 4The output shaft 19 is externally rotatably connected to the inside of the support plate 17. The bottom of the intermittent turntable 23 is rotatably connected to the top of the semicircular block 20. The output shaft 19 is externally rotatably connected to the inside of the intermittent drive plate 21. The front side of the support plate 17 is rotatably connected to the rear side of the semicircular block 20. The front side of the support plate 17 is rotatably connected to the front side of the intermittent drive plate 21. The external side of the rotating shaft 7 is rotatably connected to the inside of the rotating plate 5. The inner side of the rotating wheel 10 is rotatably connected to the outer side of the pipe 16 to be welded.

[0037] Working principle: The cylinder 4 on the right side of the circular support 3 in the push assembly generates a linear pushing force through compressed gas, which pushes the rotating plate 5 to slide. This causes the sliding block 6 to drive the slider 8 on the front side to slide inwards towards the inside of the disc 2 within the sliding groove block 9. The rotating shaft 7 connected to the sliding block 6 limits the sliding range of the rotating plate 5 to ensure its stability. The movement of the rotating plate 5 is also transmitted to the rotating plate 12 through the connecting rotating rod 11. The components connected to the upper and lower sides of the connecting rotating rod 11 have the same structure. The connecting rotating rod 11 is used to transmit the power of the cylinder 4 to the upper part, and can drive the three rotating wheels 10 to slide inwards. Then, the power is transmitted through the rotating plate 12 to drive the rotating rod 2. The connecting rotating rod 2 13 drives the follower plate 14 to move, causing the sliding block 2 15 to drive the rotating wheel 10 connected to the front side to slide. Through the power output of the cylinder 4, the three rotating wheels 10 slide inwards to accurately clamp and position the pipe.

[0038] The pipe 16 to be welded is placed at the center of the disc 2. After the equipment is started, the motor 18 on the back of the support plate 17 starts to run. The power is transmitted to the semicircular block 20 and the intermittent drive plate 21 through the output shaft 19, driving the semicircular block 20, which in turn drives the intermittent turntable 23 to move. The movement of the intermittent turntable 23 causes the clamping block 22 to clamp the pipe 16 to be welded, and at the same time drives the pipe to rotate so as to adjust to a suitable welding angle. Throughout the process, the cylinder 4 and the motor 18 work together to ensure that the position and angle of the pipe are kept correct during the welding process. The fixture achieves precise positioning of the pipe through clamping, rotating and adjusting actions, providing a stable foundation for welding.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
