[0014] Optionally, an infrared sensor is fixedly installed on the front of the screw seat, and a receiving plate is fixed on the cutting table at the position corresponding to one end of the ball screw.

[0015] Optionally, an air outlet is provided on one side of the rear end of the cutting table, and a movable frame is fixed to the long pipe at the position corresponding to the air outlet, the movable frame sliding along the inner side of the air outlet.

[0016] The technical solution provided in this disclosure may include the following beneficial effects:

[0017] This invention uses a motor to drive the first bidirectional screw to rotate, and the moving frame moves along the cutting table in a threaded engagement with the first bidirectional screw, thereby changing the distance between the two telescopic frames and adjusting it according to the width of the building pipe. The motor drives the ball screw to rotate, and the screw seat moves along the moving notch in a threaded engagement with the ball screw, thereby adjusting the position of the laser cutting device. Based on the high-precision movement of the ball screw, the laser cutting device is moved to the accurate cutting position of the building pipe.

[0018] When the vertical plate position is adjusted by the moving component, the bottom of the vertical plate slides along the side rail. The second screw is driven to rotate by the motor inside the vertical plate. The horizontal frame moves vertically in the threaded engagement with the second screw, so that the horizontal frame contacts the top of the building pipe. The telescopic frame contacts both sides of the building pipe, thereby limiting the building pipe and positioning the laser cutting device.

[0019] This invention utilizes a long tube to drive a fan. Hot air, dust, and debris generated during cutting are drawn away from the wrapping frame composed of a telescopic plate, insert plate, and elastic cloth. The debris then enters the hollow cylinder through a flexible hose, where it is filtered. Finally, it is discharged through the long tube and a movable frame via an air outlet. During this process, the position of the wrapping components changes as the cutting position shifts. The flexible hose connecting the long tube and the telescopic plate moves along the inside of the long tube, maintaining communication within the wrapping frame. Gas is released through the air vents in the hollow cylinder connected to the flexible hose. Dust and other debris are moved by the traction of the hose, and the scraper moves along the inside of the hollow cylinder to clean the inner wall of the hollow cylinder. After the cutting is completed, the wrapping component and the laser cutting device move to one end. At this time, the hose is pulled out to the maximum length, so that the hollow cylinder squeezes the baffle and opens the slag discharge port. The scraper will discharge the impurities cleaned inside the hollow cylinder from the slag discharge port. The first spring can keep the baffle blocking the hollow cylinder, and the second spring can assist the hose to be sent into the hollow cylinder. The insertion interface of the telescopic plate at the upper end can wrap around the two sides of the laser cutting device to reduce the opening within the wrapping range.

[0020] This invention allows for adjustment of the lateral and longitudinal positions of the telescopic frame via a movable component, with the laser cutting device moving synchronously. A second bidirectional screw inside the horizontal frame is driven by a motor, and the extended end of the telescopic plate engages with the threaded second bidirectional screw, allowing adjustment of the positions of the telescopic plates on both sides of the building pipe. Furthermore, by moving the insert plates at the top and bottom of the telescopic plate, an elastic cloth is wrapped around the cutting position of the building pipe. The elasticity of the cloth allows it to deform according to the contour of the building pipe, thus wrapping the entire cutting area.

[0021] The sliding frame of this invention can be moved and pulled out along the sliding table, thereby facilitating the insertion or removal of building pipes from the outside of the cutting table. A third bidirectional screw driven by a motor moves two vertical frames along the sliding frame. The distance between the two vertical frames is adjusted according to the length of the building pipe, allowing the rotating shaft at the top of the rotating frame and the electric push rod to insert into both ends of the building pipe. The electric push rod extends, working in conjunction with the extrusion plate to support the inner walls of both ends of the building pipe, thus maintaining the stability of the building pipe after installation. Based on the radius of the building pipe, a roller contacts the bottom of the building pipe. The roller slides along the sliding groove, facilitating the subsequent rotation by the drive motor and the rotation of the building pipe. The contact between the roller and the bottom of the building pipe assists in its rotation.

[0038] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0039] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown in the embodiment of this disclosure, a high-precision laser cutting device for municipal engineering is proposed, comprising: a cutting table 1, wherein a movable cavity 11 is formed on the top surface of the cutting table 1; a clamping assembly 5, wherein the clamping assembly 5 includes a sliding frame 52, wherein the sliding frame 52 is disposed at the top center of the cutting table 1, wherein two vertical frames 53 are symmetrically slidably connected inside the sliding frame 52, and three sets of electric push rods 55 are rotatably mounted on the top of the vertical frames 53 via a rotating shaft, wherein an extrusion plate 56 is rotatably mounted on the extended end of the electric push rods 55; a building pipe 12, wherein the building pipe 12 is located between the two vertical frames 53; and a lifting assembly 4, wherein the lifting assembly 4 includes a vertical plate 41, wherein vertical plates 41 are provided on both sides of the cutting table 1. 1. A horizontal frame 43 is slidably installed on the surface of the vertical plate 41; a wrapping component 3, the wrapping component 3 includes a telescopic frame 31, telescopic frames 31 are provided on both sides of the building pipe 12, insert plates 33 are slidably inserted into the top and bottom of the telescopic frame 31, elastic cloth 34 is slidably extended from both sides of the telescopic frame 31, and the elastic cloth 34 wraps around the surface of the building pipe 12, a long pipe 36 is provided at the bottom of the telescopic frame 31, and the long pipe 36 slides along the inside of the moving cavity 11, and a flexible hose 39 is slidably inserted into one end of the long pipe 36; a moving component 2, two moving frames 22 are symmetrically slidably installed on the top of the cutting table 1, and the bottom of the telescopic frame 31 slides along the surface of the moving frame 22.

[0040] When using the device, the building pipe 12 is installed inside the clamping assembly 5. The positions of the wrapping assembly 3 and the laser cutting device 61 are adjusted according to the width and height of the building pipe 12 by the moving assembly 2 and the lifting assembly 4. As the building pipe 12 rotates, the laser cutting device 61 cuts the surface of the building pipe 12. The wrapping assembly 3 wraps around the cutting area and sucks away the debris and dust generated during cutting, so as to avoid affecting the surrounding cutting environment and improve cutting efficiency.

[0041] like Figure 2 and Figure 3 As shown, in some embodiments, the moving component 2 further includes: a first bidirectional screw 21, a ball screw 23, a screw seat 24, and a moving notch 25. The first bidirectional screw 21 is rotatably mounted on the front outer wall of the cutting table 1 via a bearing seat, and the front end of the moving frame 22 is threaded onto the surface of the first bidirectional screw 21. The ball screw 23 is rotatably mounted on the side of the cutting table 1 via a bearing seat, and a screw seat 24 is threaded onto the surface of the ball screw 23. The cutting table 1 has a moving notch 25 at the top corresponding to the screw seat 24, and the screw seat 24 is fixedly connected to the bottom of the vertical plate 41 through the moving notch 25. An infrared sensor 26 is fixedly mounted on the front of the screw seat 24, and a receiving plate is fixedly mounted on one end of the cutting table 1 corresponding to the ball screw 23.

[0042] Understandably, by driving the first bidirectional screw 21 to rotate via a motor, the moving frame 22 moves along the cutting table 1 in a threaded engagement with the first bidirectional screw 21, thereby changing the distance between the two telescopic frames 31 and adjusting it according to the width of the building pipe 12. By driving the ball screw 23 to rotate via a motor, the screw seat 24 moves along the moving notch 25 in a threaded engagement with the ball screw 23, thereby adjusting the position of the laser cutting device 61. Based on the high-precision movement of the ball screw 23, the laser cutting device 61 is moved to the accurate cutting position of the building pipe 12.

[0043] like Figure 2 and Figure 4 As shown, in some embodiments, the lifting assembly 4 further includes: a side rail 42, a slide block 44, and a second screw 46. The cutting table 1 is fixed to the inner wall of the bottom of the two vertical plates 41 with the side rail 42, and the bottom of the vertical plates 41 slides along the side rail 42. The two ends of the horizontal frame 43 are fixed with slide blocks 44, and the slide blocks 44 slide along the surface of the vertical plates 41. The second screw 46 is rotatably installed inside the vertical plate 41 on one side of the horizontal frame 43, and the slide block 52 at one end of the horizontal frame 43 is threaded onto the surface of the second screw 46.

[0044] Understandably, when the moving component 2 adjusts the position of the vertical plate 41, the bottom of the vertical plate 41 slides along the side rail 42. The second screw 46 is driven to rotate by the motor inside the vertical plate 41. The horizontal frame 43 moves vertically in the threaded engagement with the second screw 46, so that the horizontal frame 43 contacts the top of the building pipe 12. In conjunction with the telescopic frame 31, it contacts both sides of the building pipe 12, thereby limiting the building pipe 12 and positioning the laser cutting device 61.

[0045] like Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the wrapping assembly 3 further includes: a telescopic plate 32, a slag discharge port 37, a movable frame 38, a limiting plate 310, a driving fan 312, a hollow cylinder 313, and a hollow cylinder 316. The outer ends of the two insert plates 33 are fixed with the telescopic plate 32, and both sides of the telescopic plate 32 are fixedly connected to the outer side of the elastic cloth 34. The bottom of the long tube 36 corresponding to the end through which the flexible hose 39 protrudes is provided with a slag discharge port 37, and the other end of the long tube 36 is rotatably mounted with a driving fan 312. The long tube 36 has a hollow cylinder 313 inside, and the hollow cylinder 316 is slidably installed inside the hollow cylinder 313. The other end of the flexible hose 39 is fixedly connected to the inside of the hollow cylinder 316, and air outlets 317 are equidistantly provided on the outer surface of the hollow cylinder 316. The long tube 36 is fixed with a limiting plate 310 on one side of the slag discharge port 37, and the flexible hose 39 slides through the limiting plate 310. The outer end of the tube 39 is inserted into the bottom of the telescopic plate 32. A scraper 315 is fixed at the end of the hollow cylinder 316 away from the hose 39, and the scraper 315 slides along the inner wall of the hollow cylinder 313. A second spring 314 is fixed between the scraper 315 and the hollow cylinder 313. A baffle 318 is provided at the end of the hollow cylinder 313 corresponding to the slag discharge port 37, and the baffle 318 slides along the inside of the long tube 36. A first spring 311 is fixed between the long tube 36 and the baffle 318. A top frame 6 is fixed at the top of both ends of the horizontal frame 43, and a laser cutting device 61 is fixed at the bottom of the middle position of the top frame 6. An insertion interface 35 is opened on the top plate 33 of the telescopic frame 31 corresponding to the position of the laser cutting device 61. An air outlet 13 is opened on one side of the rear end of the cutting table 1, and a moving frame 38 is fixed on the long tube 36 corresponding to the position of the air outlet 13. The moving frame 38 slides along the inner side of the air outlet 13.

[0046] It should be noted that the horizontal and vertical positions of the telescopic frame 31 can be adjusted by the moving component 2, and the laser cutting device 61 moves synchronously. The second bidirectional screw 45 inside the horizontal frame 43 is driven by a motor, and the extended end of the telescopic plate 32 is threaded into the second bidirectional screw 45, allowing adjustment of the position of the telescopic plates 32 on both sides of the building pipe 12. Furthermore, the insertion plates 33 at the top and bottom of the telescopic plates 32 move, wrapping the elastic cloth 34 around the cutting position of the building pipe 12. The elasticity of the elastic cloth 34 allows it to deform according to the contour of the building pipe 12, thus wrapping the entire cutting area. The fan 312 driven by the long pipe 36 is turned on, and the hot air, dust, and debris generated during cutting are sucked away from the wrapping frame composed of the telescopic plate 32, insertion plates 33, and elastic cloth 34. This debris then enters the hollow cylinder 313 through the hose 39, where it filters the dust and debris before being discharged through the long pipe 36 and the moving frame 38 from the air outlet 13. During this process, the position of the wrapping component 3 also changes as the cutting position changes. This process will change. As the telescopic plate 32 moves along the long tube 36, the flexible hose 39 extends through the inside of the long tube 36, maintaining communication within the enclosure formed by the long tube 36 and the telescopic plate 32. Gas and dust are expelled through the vents of the hollow cylinder 316 connected to the flexible hose 39. The scraper 315 moves along the inside of the hollow cylinder 313, cleaning its inner wall, due to the traction movement of the flexible hose 39. After cutting, the enclosure assembly 3 and the laser cutting device 61 move to one end. When the flexible hose 39 is pulled out to its maximum length, it squeezes the baffle 318 through the hollow cylinder 316, opening the slag discharge port 37. The scraper 315 discharges the impurities inside the hollow cylinder 313 from the slag discharge port 37. The first spring 311 can keep the baffle 318 blocking the hollow cylinder 313. The second spring 314 can assist the flexible hose 39 in being sent into the hollow cylinder 313. The insertion interface 35 of the insert plate 33 at the upper end of the telescopic plate 32 can wrap around both sides of the laser cutting device 61, thereby reducing the opening within the wrapping area.

[0047] like Figure 4 and Figure 6As shown, in some embodiments, the clamping assembly 5 further includes: a slide table 51 and a third bidirectional screw 57. The slide table 51 is fixed inside the moving cavity 11 of the cutting table 1, and the slide frame 52 is slidably inserted into the top of the slide table 51. The third bidirectional screw 57 is rotatably installed inside the slide frame 52 through a bearing. The bottom of the vertical frame 53 is threaded onto the surface of the third bidirectional screw 57. A drive motor 54 is fixed to the outer end of the vertical frame 53 at one end of the slide frame 52, and the output end of the drive motor 54 is fixedly connected to the rotating shaft on which the electric push rod 55 is installed. A groove 59 is opened on the inner surface of the vertical frame 53, and a slide plate 510 is slidably installed inside the groove 59. A third spring 511 is fixed between the top of the slide plate 510 and the inner wall of the groove 59. Two rollers 58 are symmetrically rotatably installed on the outer side of the slide plate 510, and the rollers 58 are in sliding contact with the bottom of the building pipe 12.

[0048] Understandably, the sliding frame 52 can be moved and pulled out along the sliding table 51, making it convenient to insert or remove the building pipe 12 from the outside of the cutting table 1. The motor drives the third bidirectional screw 57 to move the two vertical frames 53 along the sliding frame 52. The distance between the two vertical frames 53 is adjusted according to the length of the building pipe 12, so that the rotating shaft at the top of the rotating frame and the electric push rod 55 are inserted into both ends of the building pipe 12. The electric push rod 55 extends and, together with the extrusion plate 56, supports the inner walls of both ends of the building pipe 12, thereby maintaining the stability of the building pipe 12 after installation. According to the radius of the building pipe 12, it contacts the roller 58 that contacts the bottom of the building pipe 12. The roller 58 slides the slide plate 510 along the slide groove 59, which facilitates the subsequent drive motor 54 to drive the rotation and the rotation of the building pipe 12. The roller 58 contacts the bottom of the building pipe 12 to assist its rotation.

[0049] Working principle:

[0050] When using the device, the sliding frame 52 can be moved and pulled out along the sliding table 51, making it convenient to insert or remove the building pipe 12 from the outside of the cutting table 1. The motor drives the third bidirectional screw 57 to move the two vertical frames 53 along the sliding frame 52. The distance between the two vertical frames 53 is adjusted according to the length of the building pipe 12, so that the rotating shaft at the top of the rotating frame and the electric push rod 55 are inserted into both ends of the building pipe 12. The electric push rod 55 extends, and together with the extrusion plate 56, it supports the inner walls of both ends of the building pipe 12, thereby maintaining the stability of the building pipe 12 after installation. According to the radius of the building pipe 12, it contacts the roller shaft 58 that contacts the bottom of the building pipe 12. The roller shaft 58 slides the slide plate 510 along the slide groove 59, which is convenient for the subsequent drive motor 54 to drive the rotation and construction. The construction pipe 12 rotates, and the roller 58 contacts the bottom of the construction pipe 12 to assist its rotation, thus installing the construction pipe 12 inside the clamping assembly 5. The horizontal and vertical positions of the telescopic frame 31 can be adjusted by moving the assembly 2, and the laser cutting device 61 moves synchronously. The second bidirectional screw 45 inside the horizontal frame 43 is driven by a motor, and the extended end of the telescopic plate 32 is threaded with the second bidirectional screw 45, which can adjust the position of the telescopic plates 32 on both sides of the construction pipe 12. Then, the insert plates 33 at the top and bottom of the telescopic plate 32 move, wrapping the elastic cloth 34 around the cutting position of the construction pipe 12. The elasticity of the elastic cloth 34 can deform according to the contour of the construction pipe 12, thereby wrapping the entire cutting area. When the drive fan 312 of the long tube 36 is turned on, the hot air, dust, and debris generated during cutting are drawn away from the wrapping frame composed of the telescopic plate 32, the insert plate 33, and the elastic cloth 34. They then enter the hollow cylinder 313 through the hose 39, where the dust and debris are filtered. Finally, they are discharged through the air outlet 13 via the long tube 36 and the moving frame 38. During this process, the position of the wrapping assembly 3 changes as the cutting position changes. As the telescopic plate 32 moves, the hose 39 connecting the long tube 36 and the telescopic plate 32 extends through the interior of the long tube 36, maintaining communication between the long tube 36 and the interior of the wrapping frame composed of the telescopic plate 32. The air vents of the hollow cylinder 316 connected to the hose 39 deliver gas and dust, which are then released through the traction of the hose 39. The scraper 315 moves along the inside of the hollow cylinder 313 to clean the inner wall of the hollow cylinder 313. After cutting, the wrapping component 3 and the laser cutting device 61 move to one end. At this time, the hose 39 is pulled out to its maximum length, thereby squeezing the baffle 318 through the hollow cylinder 316 and opening the slag discharge port 37. The scraper 315 discharges the impurities inside the hollow cylinder 313 from the slag discharge port 37. The first spring 311 can keep the baffle 318 blocking the hollow cylinder 313, and the second spring 314 can assist the hose 39 to be sent into the interior of the hollow cylinder 313. The insertion interface 35 of the insert plate 33 at the upper end of the telescopic plate 32 can wrap around both sides of the laser cutting device 61 to reduce the opening within the wrapping range. When the moving component 2 adjusts the position of the vertical plate 41...The bottom of the vertical plate 41 slides along the side rail 42. The second screw 46 is driven to rotate by the motor inside the vertical plate 41. The horizontal frame 43 moves vertically in a threaded engagement with the second screw 46, bringing it into contact with the top of the building pipe 12. This, combined with the telescopic frame 31, contacts both sides of the building pipe 12, thus limiting the position of the building pipe 12 and positioning the laser cutting device 61. The first bidirectional screw 21 rotates in a motor-driven manner, and the moving frame 22 moves along the cutting table 1 in a threaded engagement with the first bidirectional screw 21, changing the distance between the two telescopic frames 31 according to the width of the building pipe 12. The ball screw 23 rotates in a motor-driven manner, and the screw seat 24 moves along the moving notch 25 in a threaded engagement with the ball screw 23, adjusting the position of the laser cutting device 61. Based on the high-precision movement of the ball screw 23, the laser cutting device 61 is moved to the accurate cutting position on the building pipe 12.
