Technical Field

[0001] This utility model belongs to the field of compressor parts manufacturing technology, and in particular relates to a pipe welding machine for compressor parts manufacturing. Background Technology

[0002] Welding is an essential step in the production of compressor parts. As the core component of nitrogen generators and oxygen filling machines, compressors contain many metal pipes and structural parts that need to be connected. The quality of the connection of these pipes and parts directly affects the performance, reliability and service life of the compressor.

[0003] Traditional welding machines present operational inconveniences when welding pipes. Traditional welding equipment often struggles to stably fix and position the pipes, making welding difficult and prone to deviations during the welding process, thus affecting the welding quality. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a pipe welding machine for the production of compressor parts, which solves the problem of inconvenience in the operation of traditional welding machines when welding pipes. Traditional welding equipment often has difficulty in stably fixing and positioning pipes, making it inconvenient to weld pipes, which leads to deviations during the welding process and affects the welding quality.

[0005] To achieve the above objectives, the main technical solutions adopted by this utility model include:

A rotating ring is rotatably mounted inside the vertical frame. A servo cylinder is fixedly mounted on the inner surface of the rotating ring. The welding head is mounted on the telescopic end of the servo cylinder. Movable clamping assemblies are provided on both sides of the vertical frame. Each movable clamping assembly includes a vertical plate, which is fixedly mounted on the top surface of the base. Multiple guide rods are fixedly mounted between the vertical plate and the base. Movable frames are slidably mounted on the multiple guide rods. An opening is provided in the movable frame. An upper servo hydraulic cylinder is fixedly mounted on the top surface of the opening.

A lower servo hydraulic cylinder is fixedly mounted on the bottom surface of the opening. A lower clamp is fixedly mounted on the telescopic end of the lower servo hydraulic cylinder. A lower V-groove is provided on the bottom surface of the lower clamp.

[0007] Furthermore, a crown gear is fixedly provided at one end of the rotating ring.

[0008] Furthermore, a frame is fixedly provided on the outer surface of the upright, a second servo motor is fixedly provided on the frame, and a drive gear is fixedly provided on the drive end of the second servo motor, the drive gear meshing with the crown gear.

[0021] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-3 As shown, this utility model provides a pipe welding machine for compressor parts production, including a base 1 and a welding head 21. A stand 2 is fixedly mounted on the top surface of the base 1. A rotating ring 3 is rotatably mounted inside the stand 2. A servo cylinder 20 is fixedly mounted on the inner surface of the rotating ring 3. The welding head 21 is installed at the telescopic end of the servo cylinder 20. Movable clamping assemblies are provided on both sides of the stand 2. The movable clamping assemblies include a vertical plate 8, which is fixedly mounted on the top surface of the base 1. Multiple guide rods 5 are fixedly mounted between the vertical plate 8 and the base 1. Movable frames 9 are slidably mounted on the multiple guide rods 5. An opening 15 is opened in the movable frame 9. An upper servo hydraulic cylinder 14 is fixedly mounted on the top surface of the opening 15. An upper clamp 16 is fixedly mounted on the telescopic end of the upper servo hydraulic cylinder 14. An opening is opened on the bottom surface of the upper clamp 16. The upper V-groove 17 has a lower servo hydraulic cylinder 11 fixedly mounted on the bottom surface of the through-hole 15. The lower servo hydraulic cylinder 11 has a lower clamp 12 fixedly mounted on its telescopic end. The bottom surface of the lower clamp 12 has a lower V-groove 13. One end of the rotating ring 3 is fixedly mounted with a crown gear 4. The outer surface of the upright frame 2 is fixedly mounted with a frame 19. The frame 19 is fixedly mounted with a second servo motor 18. The drive end of the second servo motor 18 is fixedly mounted with a drive gear 22, which meshes with the crown gear 4. The bottom surface of the movable frame 9 is fixedly mounted with a rack 7. A worm gear 6 is rotatably mounted between the upright frame 2 and the upright plate 8. The worm gear 6 meshes with the rack 7. The upright plate 8 is fixedly mounted with a first servo motor 10. The drive end of the first servo motor 10 is fixedly connected to one end of the worm gear 6. The worm gear 6 has self-locking properties.

[0023] In use, the two pipes to be welded are placed in the movable clamping assembly, specifically between the upper clamp 16 and the lower clamp 12. The upper servo hydraulic cylinder 14 extends to move the upper clamp 16 downward, and the lower servo hydraulic cylinder 11 extends to move the lower clamp 12 upward, thereby clamping the pipes. The upper V-groove 17 and the lower V-groove 13 facilitate the clamping of the pipes.

[0024] Starting the first servo motor 10 drives the worm gear 6 to rotate. The rotation of the worm gear 6 drives the rack 7 to move laterally. The lateral movement of the rack 7 drives the pipe to move laterally, moving the end of the pipe to be welded into the rotating ring 3 so that the two pipes to be welded are connected. The self-locking performance of the worm gear 6 positions the rack 7, thereby positioning the pipe.

[0025] The extension of the servo cylinder 20 can drive the welding head 21 closer to the part of the pipe to be welded. The second servo motor 18 can be started to drive the drive gear 22 to rotate. The rotation of the drive gear 22 can drive the crown gear 4 to rotate. The rotation of the crown gear 4 can drive the welding head 21 to revolve around the pipe, which facilitates the welding of the pipe.

Any modifications, alterations, substitutions, and variations made by those skilled in the art to the above embodiments are within the scope of the present invention.
