Detailed Implementation Modes

[0022] The present utility model provides a pipe cutting machine. To make the purpose, technical solution and effects of the present utility model clearer and more definite, the following further elaborates on the present utility model by way of examples with reference to the attached drawings. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the protection scope of the present utility model.

[0023] In this article, the X-axis direction is the left-right direction, the Y-axis direction is the front-back direction, and the Z-axis direction is the up-down direction.

[0024] Please refer to Figures 1-3 Figures 1-3 , the present utility model provides a pipe cutting machine, which includes a horizontal chassis 1, a fixed chuck assembly 2 and a gantry 3 arranged at the top of the front end of the horizontal chassis 1, a laser cutting assembly arranged on the gantry 3 and movable along the X-axis and Z-axis, and a movable chuck assembly 4 slidably arranged on the horizontal chassis 1 back and forth. A clamping support mechanism 5 and a variable-diameter wheel support mechanism 6 are arranged on the horizontal chassis 1. The clamping support mechanism 5 is used for clamping the pipe to make the pipe centered, the variable-diameter wheel support mechanism 6 is used for supporting the pipe, the laser cutting assembly is used for laser cutting the pipe. A vertical plate 7 is arranged at the front end of the horizontal chassis 1 and below the fixed chuck assembly 2. An air extraction and dust removal port 71 is opened on the vertical plate 7, and the air extraction and dust removal port 71 is connected to a vacuum cleaner.

[0025] In practical applications, the vacuum cleaner can be hidden inside the horizontal chassis 1. Placing the vacuum cleaner inside the horizontal chassis 1 reduces the additional floor area. For a production workshop with limited space, this can make more efficient use of the floor space and optimize the workshop layout. In addition, the distance between the vacuum cleaner and the air extraction and dust removal port 71 is shortened, reducing the length of the pipeline. This not only simplifies the installation process but also may reduce the suction loss and improve the dust removal efficiency.

[0026] Compared with the prior art, by connecting the air extraction and dust removal port 71 arranged at the front end of the horizontal chassis 1 to the vacuum cleaner, the metal dust generated during the laser cutting process can be effectively collected and processed, significantly reducing the dust concentration in the workshop, improving the working environment of workers, and reducing health risks.

[0027] Preferably, the air extraction and dust removal port 71 is a round hole. The round-hole cross-section air extraction and dust removal port 71 can provide a more uniform air flow distribution, reduce air flow dead angles, ensure that dust approaching from all directions can be effectively captured, and improve the air extraction efficiency. Most commercial vacuum cleaner interfaces are designed to be round. Using the round air extraction and dust removal port 71 can be directly connected without a special adapter, simplifying the installation process.

[0028] Specifically, the fixed chuck assembly 2 includes a fixed chuck body 21 and two first position-adjusting feet 22 arranged at the bottom of the fixed chuck body 21. There is a first adjusting block 23 fixed on the horizontal chassis 1 beside the two first position-adjusting feet 22. Each first adjusting block 23 is provided with a first pushing screw (not shown in the figure) facing the corresponding first position-adjusting foot 22. The first position-adjusting foot 22 is provided with a first elongated hole 221 extending in the left-right direction. The first position-adjusting foot 22 is connected to the threaded hole on the horizontal chassis 1 through a first locking screw (not shown in the figure) passing through the first elongated hole 221. When adjusting the left-right position of the fixed chuck body 21, loosen the first locking screw, and by turning the first pushing screws on both sides of the fixed chuck body 21, the first position-adjusting feet 22 in contact therewith are pushed, thereby driving the fixed chuck body 21 to move left and right for fine adjustment. Since the first position-adjusting foot 22 is provided with the first elongated hole 221, the lateral fine adjustment of the fixed chuck body 21 is achieved. Once the position adjustment is completed, tighten the first locking screw to engage it with the threaded hole on the horizontal chassis 1, thereby fixing the position of the first position-adjusting foot 22, and further locking the final position of the fixed chuck body 21.

[0029] By finely adjusting the fixed chuck body 21, it is ensured that the center line of the pipe is accurately aligned with the cutting path of the laser cutting assembly, improving the cutting accuracy and the finished product rate.

[0030] In this embodiment, the horizontal chassis 1 is provided with a Y-axis rack 81 extending in the front-rear direction and two Y-axis guide rails 82 extending in the front-rear direction. The moving chuck assembly 4 includes a slide plate 41, a moving chuck body 42 arranged on the slide plate 41, and a moving drive motor 43. The output end of the moving drive motor 43 is provided with a Y-axis gear meshing with the Y-axis rack 81. The slide plate 41 is slidably connected to the Y-axis guide rail 82 through a Y-axis slider 83. The combination of the Y-axis guide rail 82 and the Y-axis slider 83 provides stable support and guidance. Even in the case of high-speed movement or heavy load, the smooth operation of the moving chuck assembly 4 can be maintained, reducing shaking and vibration, and improving the reliability and durability of the equipment.

[0031] Similarly, the movable chuck assembly 4 further includes two second adjusting feet 44 provided at the bottom of the movable chuck body 42. A second adjusting block 46 fixed to the slide plate 41 is provided beside the two second adjusting feet 44. Each second adjusting block 46 is provided with a second push screw facing the corresponding second adjusting foot 44. The second adjusting foot 44 is provided with a second long hole 45 extending in the left-right direction. The second adjusting foot 44 is connected to a threaded hole on the slide plate 41 through a second locking screw passing through the second long hole 45. When adjusting the left-right position of the movable chuck body 42, loosen the second locking screw, and by turning the second push screws on both sides of the movable chuck body 42, the second adjusting feet 44 in contact therewith are pushed, thereby driving the movable chuck body 42 to move left and right. Because the second long hole 45 is provided on the second adjusting foot 44, the lateral fine adjustment of the movable chuck body 42 is enabled. Once the adjustment is completed, by tightening the second locking screw to engage with the threaded hole on the slide plate 41, the position of the second adjusting foot 44 is fixed, and thus the final position of the movable chuck body 42 is locked.

[0032] Perform fine adjustment of the movable chuck body 42 in the left-right direction to ensure that the movable chuck body 42 is coaxially aligned with the fixed chuck body 21, improving the machining accuracy.

[0033] Specifically, the laser cutting assembly includes an X-axis rack 91 and an X-axis guide rail 92 provided on the top beam of the gantry 3, an X-axis slide table 93 slidably connected to the X-axis guide rail 92 through an X-axis slider, an X-axis driving motor 94 provided on the X-axis slide table 93, a Z-axis linear module 95 provided on the X-axis slide table 93, and a laser cutting head 96 provided on the slide table of the Z-axis linear module 95. The output end of the X-axis driving motor 94 is provided with an X-axis gear meshing with the X-axis rack 91. The laser cutting head 96 can not only move horizontally in the X-axis direction through the X-axis driving motor 94 and the X-axis gear-rack system, but also move vertically in the Z-axis direction through the Z-axis linear module 95. Such three-dimensional movement ability ensures that the laser cutting head 96 can accurately cut the pipe according to the preset path, meeting the processing requirements of various complex shapes and sizes.

[0034] A receiving auxiliary bracket 11 is connected to the front end of the horizontal chassis 1, and the receiving mechanism is installed on the receiving auxiliary bracket 11. One end of the receiving auxiliary bracket 11 is fixedly connected to the front end of the horizontal chassis 1, and the other end extends forward, thus enclosing a blanking area. The receiving mechanism can flexibly receive and place the cut pipe section, avoiding possible damage when the pipe section directly falls to the ground or a hard surface, and protecting the integrity and appearance quality of the product.

[0035] Please refer to Figure 5, specifically, the variable-diameter wheel support mechanism 6 includes a mounting plate 61 fixed on the horizontal chassis 1, a first lifting cylinder 62 arranged upward on the fixed seat, a receiving frame 63 drivingly connected to the first lifting cylinder 62, a support shaft 64 fixed on the receiving frame 63, a variable-diameter wheel 65 rotatably arranged on the support shaft 64, and a locking structure 66 for fixedly locking the variable-diameter wheel 65. According to the diameter of the pipe to be processed, the support contact surface of the variable-diameter wheel 65 is rotated and adjusted. After the adjustment is completed, the variable-diameter wheel 65 is locked by the locking structure 66. The first lifting cylinder 62 drives the variable-diameter wheel 65 on the receiving frame 63 to rise. When the pipe is being cut, the variable-diameter wheel 65 can effectively support the pipe, reduce the swing of the pipe in the up-down, left-right directions, and improve the cutting accuracy.

[0036] Please refer to Figure 4 , specifically, the clamping support mechanism 5 includes a T-shaped plate 51, two clamping blocks 52 symmetrically arranged left and right and slidably arranged on the T-shaped plate 51, a clamping drive cylinder 53 for driving the two clamping blocks 52 to approach or separate from each other, and a lifting assembly for driving the T-shaped plate to move up and down. Specifically, the output end of the clamping drive cylinder 53 drives the corresponding clamping block 52 to move through two pull rods 58. The lifting assembly includes a lifting seat 54 and a second lifting cylinder 55 arranged upward on the lifting seat 54. The end of the piston rod of the second lifting cylinder 55 is fixedly connected to the T-shaped plate 51. A support 56 is provided on the horizontal chassis 1. The lifting seat 54 is vertically slidably arranged on the support 56. A height-adjusting screw 57 pressing against the support 56 is arranged on the lifting seat 54. By turning the height-adjusting screw 57, the initial height of the lifting seat 54 and the mechanism arranged on the lifting seat 54 can be adjusted, and the adjustment is flexible.

[0037] When the second lifting cylinder 55 extends, it drives the clamping blocks 52 on the T-shaped plate 51 to rise as a whole; when the piston rod of the clamping drive cylinder 53 contracts, the pull rods 58 drive the two clamping blocks 52 to approach each other, thereby clamping the pipe; by the extension of the clamping drive cylinder 53, the pull rods 58 drive the two clamping blocks 52 to separate from each other, thereby loosening the pipe. The loosening or clamping of the pipe is realized by the extension or contraction of the clamping drive cylinder 53, and the follow-up clamping of the pipe is realized.
