Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to a stable clamping and guiding mechanism of a laser cutting machine for steel pipe processing. Background Art

[0002] In the laser cutting process of steel pipes and other steel structures, a stable and accurate clamping and guiding mechanism is crucial. With the continuous advancement of industrial manufacturing technology, laser cutting is widely used in the processing of various metal materials due to its high precision and high efficiency. However, for special steel structure materials such as steel pipes, there are some unique technical challenges when performing laser cutting.

[0003] The outer ring and horizontal position cutting of steel pipes are important links in the laser cutting process. Although the existing clamping structure can clamp and rotate the steel pipe, in actual operation, it is often impossible to ensure that the steel pipe can be quickly and stably moved and adjusted in the horizontal direction while rotating. This problem seriously affects the accuracy and efficiency of laser cutting, increases the error rate in the processing process, and may even lead to cutting failure, resulting in material waste and increased production costs.

[0004] In addition, the existing clamping mechanism is often not designed to take into full consideration factors such as the change in steel pipe size and the vibration generated during processing, which further affects the stability and accuracy of laser cutting. Especially when cutting slender steel pipes, the existing support device is difficult to effectively support the pipes because the pipes tend to sag under their own gravity, causing the cutting trajectory to deviate from expectations, further reducing the cutting accuracy.

[0040] A placement opening 22 is provided at one end of the fixture housing 11, a movable opening 23 penetrating the fixture housing 11 is provided at one side of the top, and a rectangular outer frame 18 is provided outside the fixture housing 11 and near the movable opening 23;

[0041] A clamping module 14 is arranged inside the fixture housing 11. The clamping module 14 includes two horizontal and symmetrically arranged horizontal guide frames 19 and two vertical and symmetrically arranged vertical guide frames 20. The two horizontal guide frames 19 are arranged near the placement opening 22, and the two vertical guide frames 20 are arranged near the movable opening 23. Both sides of the two horizontal guide frames 19 are slidably connected to the inner wall of the fixture housing 11, and both sides of the two vertical guide frames 20 are slidably connected to the inner wall of the rectangular outer frame 18. A bidirectional driving module 12 is arranged on one side of the fixture housing 11 and on the top of the rectangular outer frame 18. The output end of the bidirectional driving module 12 is respectively connected and matched with the side walls of the two adjacent horizontal guide frames 19 or the two vertical guide frames 20.

[0042] A plurality of guide rollers 33 are rotatably connected inside the two horizontal guide frames 19 and the two vertical guide frames 20. A steel pipe 7 is horizontally arranged inside the clamp housing 11. The steel pipe 7 is located between the two horizontal guide frames 19 or the two vertical guide frames 20. A positioning assembly connected to the inner wall of the clamp housing 11 is provided at one end of the steel pipe 7. The output end of the positioning assembly is detachably connected to the outer ring of the steel pipe 7.

[0043] According to the above embodiment, the working process of the stable clamping and guiding mechanism is as follows: First, the steel pipe 7 is placed in the clamping module 14 through the placement port 22 of the clamp housing 11. Then, the positioning component positions and firmly connects the steel pipe 7 to ensure the accuracy of its position. Subsequently, the bidirectional driving module 12 is started to drive the horizontal guide frame 19 and the vertical guide frame 20 to stably clamp the steel pipe 7 through the guide rollers 33 inside them. When the steel pipe 7 is firmly clamped, the rotating motor 16 starts to work, and drives the clamp housing 11 and the steel pipe 7 to rotate as a whole through the mounting plate 10 and the mounting frame to meet the laser cutting requirements of the outer ring of the steel pipe. At the same time, the CNC machine tool 9 accurately controls the horizontal movement of the mounting plate 10, the rotating motor 16, the clamp housing 11 and the steel pipe 7 through the horizontal moving component, thereby realizing accurate cutting of the horizontal position of the steel pipe. During the cutting process, the adjusting cylinder 21 can fine-tune the position of the clamp housing 11 and the steel pipe 7 according to the cutting requirements to ensure the accuracy of the cutting. The entire machining process is carried out in a closed machine tool cover 1, which effectively isolates the machining area. At the same time, the configuration of the conical cover 2 and the connecting pipe can timely remove the smoke and dust generated during the machining process and maintain the cleanliness of the machining environment.

[0044] The stable clamping and guiding mechanism of the technical solution has shown significant beneficial effects on the technical problems in the steel pipe laser cutting process. First, the movement of the horizontal guide frame 19 and the vertical guide frame 20 is precisely controlled by the bidirectional drive module 12, so as to realize the fast and stable clamping of the steel pipe 7, ensure the stability of the steel pipe during rotation and horizontal movement, thereby greatly improving the accuracy and efficiency of laser cutting. This improvement not only significantly reduces the processing error rate, but also effectively avoids the cutting failure caused by unstable clamping, reduces material waste, and reduces production costs. Secondly, the mechanism has excellent adaptability, can flexibly cope with steel pipes of different sizes, and can achieve rapid positioning and fixation through positioning components, further improving production efficiency. In addition, considering the problem that the slender steel pipe may sag due to its own gravity during processing, the mechanism effectively prevents the deviation of the cutting trajectory through precise clamping and adjustment functions, and ensures the cutting accuracy of the slender steel pipe. Finally, the design of the machine tool cover 1 and the conical cover 2 not only protects the processing environment, but also reduces the health risks of the operator by timely removing smoke and dust, and improves the comfort and safety of the working environment. In summary, this technical solution has achieved remarkable results in improving the accuracy, efficiency and operating environment of steel pipe laser cutting, and has made important contributions to the technological progress of the steel pipe processing industry.

[0045] Example 2, refer to Figure 1-10 The horizontal moving assembly includes two symmetrically arranged pushing cylinders 13, one end of the pushing cylinder 13 is fixedly connected to the side wall bolts of the CNC machine tool 9, the output end of the pushing cylinder 13 is connected to a connecting bracket 17, and the end of the connecting bracket 17 away from the pushing cylinder 13 is connected to the side wall of the mounting plate 10.

[0046] Two first moving grooves 24 are formed on both sides of the fixture housing 11 , and two second moving grooves 38 are formed symmetrically on the top and bottom of the rectangular outer frame 18 .

[0047] The rectangular outer frame 18 is made of metal, and two inner walls of the rectangular outer frame 18 are fixedly connected to the side walls of the fixture housing 11 by bolts.

[0048] The bidirectional drive module 12 includes a bidirectional screw rod 34 and a drive motor. Both ends of the bidirectional screw rod 34 are rotatably connected to a fixed plate, and the fixed plate is connected to the side wall of the fixture housing 11 or the rectangular outer frame 18. A driven gear plate 36 is sleeved at the center of the outer ring of the bidirectional screw rod 34. The drive motor is arranged on one side of the driven gear plate 36 and is connected to the side wall of the fixture housing 11 or the rectangular outer frame 18 through a mounting seat 37. The output shaft of the drive motor is transmission-connected to a driving gear plate 35 that is meshed with the driven gear plate 36 through a latching tooth.

[0049] According to the above embodiments, the stable clamping and guiding mechanism of the laser cutting machine for steel pipe processing has been further refined and optimized. The working process is as follows: when the fixture housing 11 and the steel pipe 7 therein need to be moved, the horizontal moving component starts to work. The push cylinder 13 is started, and the mounting plate 10 and all the components thereon are pushed to move horizontally through the connecting bracket 17. This design makes the movement smoother and more precise, ensuring the accuracy of laser cutting. At the same time, the fixture housing 11 and the rectangular outer frame 18 provide a stable sliding path for the horizontal guide frame 19 and the vertical guide frame 20 through the moving groove 1 24 and the moving groove 2 38. Under the control of the bidirectional drive module 12, the bidirectional screw 34 rotates, and the horizontal guide frame 19 and the vertical guide frame 20 are accurately driven to move inside the fixture housing 11 and the rectangular outer frame 18 through the meshing transmission of the driven gear plate 36 and the driving gear plate 35, thereby realizing stable clamping of the steel pipe 7. In this process, the drive motor provides power to ensure the accuracy and rapidity of the clamping action. Overall, the refined design of the moving and clamping mechanism makes the laser cutting process of steel pipes more efficient and precise.

[0050] First, by introducing the horizontal moving assembly composed of the push cylinder 13 and the connecting bracket 17, the smooth and precise horizontal movement of the clamp housing 11 and the steel pipe 7 is achieved, which greatly improves the accuracy and operating efficiency of laser cutting. Secondly, the moving groove 1 24 and the moving groove 2 38 opened on the clamp housing 11 and the rectangular outer frame 18 provide a stable guide for the clamping frame, ensuring the stability and reliability of the clamping process. Furthermore, the bidirectional screw 34 and the gear plate transmission system in the bidirectional drive module 12 not only provide a powerful driving force, but also ensure the fine control of the clamping action, thereby effectively responding to the challenges brought by the size change and processing vibration of the steel pipe. Especially when cutting slender steel pipes, this optimized design can significantly reduce the cutting deviation caused by the sagging of the pipe, and further improve the cutting accuracy. Finally, the rectangular outer frame 18 made of metal material enhances the rigidity and durability of the overall structure, providing a guarantee for long-term stable operation. In summary, the optimized design of Example 2 shows significant advantages in improving the stability, accuracy and durability of steel pipe laser cutting.

[0051] Example 3, refer to Figure 1-10 The movable groove 1 24 and the movable groove 2 38 have the same size. The centers of both sides of the two horizontal guide frames 19 and the top and bottom centers of the two vertical guide frames 20 are connected with movable blocks 31. The movable blocks 31 slide in coordination with the movable groove 1 24 and the movable groove 2 38. One end of the movable block 31 close to the bidirectional screw rod 34 is connected with a threaded sleeve that is threadedly connected to the bidirectional screw rod 34.

[0052] The inside of the moving groove 1 24 and the moving groove 2 38 are both connected with a guide rod 32 , and one end of the guide rod 32 passes through the adjacent moving block 31 through a sliding sleeve.

[0053] The positioning assembly includes a positioning cylinder 15 connected to the inner wall of the fixture housing 11, one side of the positioning cylinder 15 is connected to a cover plate, one side of the cover plate is provided with a plurality of slide grooves 29, the interior of the slide groove 29 is slidably connected with a clamping block 27, one end of the clamping block 27 extends to the interior of the positioning cylinder 15, one side of the extended end of the clamping block 27 is elastically connected to the inner wall of the positioning cylinder 15 through a compression spring 28, and the other side is connected to a magnet plate 26, a mounting column 30 is connected to the center of the bottom of the inner cavity of the positioning cylinder 15, one end of the mounting column 30 is connected to the side wall of the cover plate, and the outer ring of the mounting column 30 is connected to a plurality of electromagnets 25, and the plurality of electromagnets 25 are magnetically matched with the adjacent magnet plates 26;

[0054] A mounting groove 5 is provided on the inner wall of the conical cover 2 on one side close to the machine tool outer cover 1 , and a filter plate 6 is fixedly connected to the inner bolts of the mounting groove 5 .

[0055] According to the above embodiment, the specific working process is as follows: when the steel pipe 7 is placed in the fixture housing 11, the positioning cylinder 15 plays a key role. The electromagnet 25 generates magnetism after being energized, and generates magnetic attraction with the magnet plate 26 on the clamping block 27, so that the clamping block 27 is pushed toward the steel pipe 7 through the extrusion spring 28 to achieve stable clamping. This design not only ensures the accurate positioning of the steel pipe, but also provides an adjustable clamping force to adapt to steel pipes of different sizes and weights. At the same time, the horizontal guide frame 19 and the vertical guide frame 20 slide stably in the moving groove 1 24 and the moving groove 2 38 through the moving block 31, and the guide rod 32 further enhances the stability and accuracy of the sliding. The rotation of the bidirectional screw 34 drives the moving block 31 through the threaded sleeve, thereby accurately controlling the movement of the frame to achieve the clamping and release of the steel pipe. In addition, the filter plate 6 inside the conical cover 2 effectively filters the smoke generated during the processing, maintains the cleanliness inside the machine tool, and ensures the smooth progress of laser cutting.

[0056] Beneficial effects:

At the same time, this design can flexibly adapt to steel pipes of different sizes. By adjusting the current intensity of the electromagnet 25, the size of the clamping force can be controlled, thereby ensuring the stable clamping of steel pipes 7 of different specifications. Secondly, the introduction of the moving block 31 and the guide rod 32 enhances the moving stability and accuracy of the clamping frame, effectively reduces the vibration and deviation during the processing, and thus improves the accuracy and quality of laser cutting. Furthermore, the precise control of the bidirectional screw 34 makes the clamping and releasing actions faster and more accurate, further shortens the processing cycle, and improves production efficiency. Finally, the filter plate 6 in the conical cover 2 effectively removes processing smoke, protects the internal components of the machine tool, prolongs the service life of the equipment, and also improves the working environment and reduces the health risks to the operator. In summary, Example 3 significantly improves the positioning accuracy, clamping stability and processing efficiency of steel pipe laser cutting through a series of optimized designs.
