Technical Field

[0001] This utility model relates to the field of large-size special pipes, specifically a laser CNC machining technology and equipment for large-size special pipes. Background Technology

[0002] In the field of laser CNC machining of large-size special pipes, due to the large volume, heavy weight and diverse specifications of the pipes, the machining process faces many technical challenges. Large-size special pipes are processed before use, such as cutting.

[0003] During the processing of existing large-size special pipelines, due to their large size, they need to be rotated while being processed. The pipeline's transport and circumferential rotation mostly rely on independent equipment, requiring frequent manual switching of support and clamping devices. This not only makes the process connections cumbersome but also easily affects the processing accuracy due to positioning deviations. At the same time, the existing fixing mechanisms are difficult to adapt to the stable clamping of pipelines with different inner diameters. Hard contact clamping can easily damage the inner wall, while flexible clamping often causes slippage due to insufficient friction, affecting the stability of transport or rotation.

[0004] Therefore, it is necessary to design a new type of laser CNC machining technology and equipment for large-size special pipes to solve the above problems. Utility Model Content

Above the machining table are multiple rollers (first and second) for supporting the large-size special pipes. When the multiple rollers (first) support the large-size special pipe, the large-size special pipe can move radially.

Multiple rollers 12 can be raised and lowered by hydraulic rod 19, and multiple rollers 23 can be raised and lowered synchronously by hydraulic rod 20.

[0027] Specifically, one end of the processing table 1 is provided with a bracket 11, one side of the bracket 11 is provided with a push plate 12, the processing table 1 is provided with a moving groove 13, one side of the bracket 11 is provided with a hydraulic rod 14 for driving the push plate 12 to move, the push plate 12 is provided with a fixing component, the bracket 11 is fixedly connected to one end of the processing table 1, the moving groove 13 is opened on the processing table 1, the push plate 12 is slidably connected to the moving groove 13, the hydraulic rod 14 can be directly purchased from the market, the extension and retraction of the hydraulic rod 14 can drive the push plate 12 to move, and the push plate 12 can facilitate the transportation of pipelines.

[0028] The fixing assembly includes a positioning rod 15 rotatably mounted on a push plate 12. The positioning rod 15 has multiple storage slots 16, and a half-gear 17 is rotatably connected to each storage slot 16. A top rod 18 is fixedly connected to each half-gear 17. The positioning rod 15 has a sliding groove 19 inside, and a sliding strip 20 inside the sliding groove 19. The sliding strip 20 has multiple racks 21, which mesh with the half-gear 17. One side of the sliding strip 20 has an internally threaded sleeve 22, and one end of the sliding strip 20 is rotatably connected to a screw 23, which is screwed into the internally threaded sleeve 22. The end of the top rod 18 has a rubber sleeve 27. The positioning rod 15 is rotatably connected to the push plate 12 via a bearing. The storage slots 16 are located on the outer side of the positioning plate, and the multiple storage slots 16 are evenly arranged on the circumferential surface of the positioning rod 15. The preferred number of storage slots is... The system consists of three components: a half-gear 17 rotatably connected to the inside of the receiving groove 16; a push rod 18 fixedly connected to the half-gear 17; a sliding groove 19 formed inside the positioning rod 15; a sliding strip 20 slidably connected inside the sliding groove 19; a rack 21 formed on the sliding strip 20 and meshing with the half-gear 17; an internally threaded sleeve 22 fixedly connected to one end of the sliding strip 20; and a screw 23 rotatably connected to one end of the sliding strip 20. The screw 23 is screwed to the internally threaded sleeve 22. The rotation of the screw 23 can drive the sliding strip 20 to move through the internally threaded sleeve 22. The movement of the sliding strip 20 can drive the push rod 18 to rotate through the rack 21 and the half-gear 17. A rubber sleeve 27 wraps around the end of the push rod 18. When multiple push rods 18 are opened, the rubber sleeve 27 can abut against the inner wall of the pipe. The friction between the rubber sleeve 27 and the inner wall of the pipe will keep the positioning rod 15 relatively fixed to the pipe, facilitating the movement or rotation of the pipe.

[0029] Based on the above embodiments, specifically, a gear ring 24 is fixedly connected to the positioning rod 15, a motor 25 is provided on one side of the push plate 12, and a drive gear 26 is provided at the output end of the motor 25. The drive gear 26 meshes with the gear ring 24, and the gear ring 24 is fixedly connected to one end of the positioning rod 15. The motor 25 can be purchased directly from the market, and the drive gear 26 is fixedly connected to the output shaft of the motor 25. The motor 25 can drive the positioning rod 15 to rotate through the drive gear 26 and the gear ring 24, which facilitates the rotation of the pipeline.

[0030] Working principle: Before use, the hydraulic rod 10 lowers multiple rollers 3, which then support the large-sized special steel pipe. During use, the large-sized special steel pipe to be processed is placed on the rollers 2, allowing it to move laterally. The positioning rod 15 is then inserted into the pipe, and the screw 23 is rotated. This rotation drives the slide bar 20 through the internal threaded sleeve 22, which in turn drives the multiple half-gears 17 to rotate synchronously. The rotation of the half gear 17 opens the push rod 18, and the multiple push rods 18 can provide internal support for the pipeline. At this time, the positioning rod 15 is fixed to the large-size special pipeline. When the pipeline needs to be transported, the push plate 12 is moved by the hydraulic rod 14. The movement of the push plate 12 can drive the large-size special pipeline to move. When the pipeline needs to be rotated, the toothed ring 24 is rotated by the motor 25 and the drive gear 26 on it. The rotation of the toothed ring 24 can drive the pipeline to rotate through the positioning rod 15, which facilitates the processing of large-size special pipelines.
