It has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, low processing costs, etc. It will gradually improve or replace traditional metal cutting process equipment. Fully automatic laser tube cutting machines are widely used in metal processing, machinery manufacturing, automobile manufacturing, aerospace, shipbuilding and other fields.

With the continuous advancement of technology and the continuous development of the market, fully automatic laser tube cutting machines will develop in the direction of higher power, higher precision and more intelligence. The following problems exist in the existing technology:

[0003] Existing fully automatic laser pipe cutting machines do not have a horizontal positioning component for the cutting head, so it becomes very difficult to achieve precise adjustment of the cutting head in the horizontal direction. When cutting pipes, one may only be able to rely on rough estimation and manual adjustment of the position of the cutting head. This method has large errors and it is difficult to accurately position the cutting head at the specific position where the pipe needs to be cut, resulting in a significant decrease in cutting accuracy, which cannot meet high-precision cutting requirements and increases the scrap rate. In addition, since the existing device cannot dynamically adjust the distance between the cutting head and the pipe to be cut in real time, when it is necessary to switch from segmented cutting to different types of cutting operations such as fine engraving, the fixed cutting head spacing cannot adapt to the new cutting requirements, which limits the functional scalability of the equipment and increases the complexity and cost of operation. At the same time, the lack of real-time dynamic adjustment capability will significantly reduce the overall cutting efficiency. Utility Model Content

[0024] like Figure 3 、 Figure 4 、 Figure 5As shown, the cutting head horizontal positioning assembly 2 includes a fixed frame 21, a gantry 29 and a fixed frame 292. The left and right sides of the bottom of the gantry 29 are fixedly connected to the roller group 27. The left and right sides of the top of the fixed frame 10 are fixedly connected to the slide rail 26. The outer walls of the left and right slide rails 26 are movably connected to the left and right roller groups 27 respectively. The upper left side of the fixed frame 21 is fixedly connected to the motor 22. The output end of the motor 22 passes through the interior of the fixed frame 21 and is fixedly connected to the pulley 23. The inner of the fixed frame 21 A pulley 24 is rotatably connected to the lower part, and a belt is provided on the outer wall of the pulley 24 and the pulley 1 23. The right side of the pulley 24 is fixedly connected to a rotating shaft 1 that passes through the outer wall of the right side of the fixed frame 1 21. The right end of the rotating shaft 1 is fixedly connected to a gear 1 25. A rack 20 is fixedly connected to the upper left wall of the fixed frame 10, and the top of the rack 20 is meshed with the gear 1 25. The right side of the fixed frame 1 21 is fixedly connected to an L-shaped fixing plate 1 28, and the right side of the L-shaped fixing plate 1 28 is fixedly connected to the bottom of the left wall of the gantry 29.

[0025] like Figure 3 、 Figure 4 、 Figure 5 As shown, the front side of the gantry 29 is fixedly connected to a guide rail 291, and the outer wall of the guide rail 291 is slidably connected to a slider 1 290. The rear side of the gantry 29 is fixedly connected to a rack 296. The right side of the rear side wall of the fixed frame 292 is fixedly connected to a motor 293. The output end of the motor 293 passes through the interior of the fixed frame 292 and is fixedly connected to a pulley 3 294. The left side of the interior of the fixed frame 292 is rotatably connected to a pulley 4 295. The pulley 4 295 and the pulley 3 The outer wall of 294 is provided with a belt, and the front side of pulley four 295 is fixedly connected to the rotating shaft two that passes through the front side wall of the fixed frame two 292, and the front side of the rotating shaft two is fixedly connected to the gear two 297 that is meshed with the rack two 296, and the front side of the fixed frame two 292 is fixedly connected to the L-shaped fixing plate two 298, and the front sides of the slider one 290 and the L-shaped fixing plate two 298 are fixedly connected to the fixing seat 299, and the PLC controller 12 is electrically connected to the motor one 22 and the motor two 293 respectively.

[0026] When the laser cutting head 391 needs to be adjusted forward and backward in the horizontal direction, the PLC controller 12 will issue a command to start the motor 1 22. The output end of the motor 1 22 drives the pulley 1 23 to rotate. Since the pulley 1 23 and the pulley 2 24 are connected by a belt, the pulley 2 24 will also rotate with the pulley 1 23. When the pulley 2 24 rotates, the rotating shaft 1 fixed on its right side also rotates, thereby causing the gear 1 25 fixed on the right end of the rotating shaft 1 to start rotating. During the rotation of the gear 1 25, according to the gear and the gear According to the meshing transmission principle of the strips, the fixed frame 21 will move back and forth in the horizontal direction along the slide rail 26. At the same time, the right side of the fixed frame 21 is fixedly connected to the bottom of the left wall of the gantry 29 through the L-shaped fixed plate 28. Therefore, when the fixed frame 21 moves horizontally, the gantry 29 will also move back and forth in the horizontal direction. The left and right sides of the bottom of the gantry 29 are movably connected to the slide rail 26 through the roller group 27, ensuring the smooth movement of the fixed frame 21 and the gantry 29, thereby driving the cutting head to achieve preliminary positioning in the horizontal direction.

[0027] When the laser cutting head 391 needs to be adjusted left and right in the horizontal direction, the PLC controller 12 will control the motor 293 to start. After the motor 293 is started, its output end drives the pulley 3 294 to rotate, and through the belt transmission, the pulley 4 295 also rotates. When the pulley 4 295 rotates, the rotating shaft 2 rotates accordingly, and then drives the gear 2 297 fixed to the front side of the rotating shaft 2 to rotate. Since the gear 2 297 and the rack 2 296 are meshed and connected, during the rotation of the gear 2 297, the fixed frame 2 292 will rotate according to the meshing transmission principle of the gear and the rack. , it moves horizontally left and right along the gantry 29. When the fixed frame 292 moves, the L-shaped fixed plate 298 connected thereto drives the fixed seat 299 to move left and right. At the same time, the guide rail 291 and the slider 1 290 make the fixed seat 299 more stable during the left and right movement. Through the provided cutting head horizontal positioning component 2, the horizontal position of the laser cutting head 391 can be accurately adjusted, thereby ensuring the accuracy of the cutting path, improving the cutting accuracy, making the finished size of the cut pipe more in line with the design requirements, and reducing the generation of waste due to cutting position deviation.

[0028] like Figure 6As shown, the real-time dynamic cutting head spacing adjustment component 3 includes a motor three 31, which is fixedly connected to the top of the fixed seat 299. The upper and lower inner walls of the fixed seat 299 are rotatably connected with screws 32. The top of the screw 32 passes through the top of the fixed seat 299 and is fixedly connected to the output end of the motor three 31. The upper and lower inner walls of the fixed seat 299 are fixedly connected with sliding rods 393 on both sides. The outer walls of the left and right sliding rods 393 are slidably connected with two sliders 2 34. The front sides of the four sliders 2 34 are fixedly connected with a lifting plate 35. The outer wall of the screw 32 is threadedly connected with a nut 33 fixedly connected to the rear side wall of the lifting plate 35.

[0029] like Figure 6 As shown, the front side of the lifting plate 35 is fixedly connected to two left and right symmetrical side plates 36, the left side wall of the left side plate 36 is fixedly connected to a motor four 37, the opposite surfaces of the left and right side plates 36 are rotatably connected to a worm 38, the left end of the worm 38 passes through the left side wall of the left side plate 36 and is fixedly connected to the output end of the motor four 37, the lower part of the worm 38 is meshed with a worm gear 39 rotatably connected to the lifting plate 35, the front side of the worm gear 39 is fixedly connected to two upper and lower symmetrical connecting blocks 390, the interior of the upper and lower connecting blocks 390 is fixedly connected to a laser cutting head 391, the bottom of the lower connecting block 390 is fixedly connected to a laser ranging sensor 392, and the PLC controller 12 is electrically connected to the motor three 31, the motor four 37, and the laser ranging sensor 392 respectively.

[0030] When it is necessary to adjust the distance between the laser cutting head 391 and the pipe to be cut, the PLC controller 12 will control the motor three 31 to start according to the information feedback from the laser ranging sensor 392. After the motor three 31 is started, it drives the screw 32 to rotate. When the screw 32 rotates, the nut 33 will move up and down along the screw 32. Since the nut 33 is fixedly connected to the lifting plate 35, and the lifting plate 35 slides on the slide rod 393 through the slider 2 34, the lifting plate 35 will move up and down along the slide rod 393 as the nut 33 moves, thereby realizing the preliminary spacing adjustment of the cutting head in the vertical direction.

[0031] When further fine-tuning of the angle or position of the laser cutting head 391 is required, the PLC controller 12 controls the motor 4 37 to start. After starting, the motor 4 37 drives the worm 38 to rotate, and the rotation of the worm 38 drives the worm gear 39 to rotate. When the worm gear 39 rotates, the connecting block 390 rotates accordingly, thereby changing the position and angle of the laser cutting head 391 and the laser ranging sensor 392, thereby achieving real-time dynamic adjustment of the distance between the laser cutting head 391 and the pipe to be cut, as well as the cutting angle. Throughout the cutting process, various components work together. Through the precise control of the PLC controller 12, the position, distance, and angle of the laser cutting head 391 are continuously adjusted, thereby achieving accurate and efficient cutting of the pipe. The real-time dynamic cutting head distance adjustment component 3 is provided, so that the device can perform fine engraving or localization on the pipe surface, thereby flexibly meeting these diverse cutting requirements and enhancing the functional versatility of the fully automatic laser pipe cutting machine. At the same time, reasonable adjustment of the distance between the laser cutting head 391 and the pipe to be cut can allow the laser energy to act more fully on the pipe, accelerate the cutting speed, and thus improve the overall cutting efficiency.

[0032] It should be noted that the PLC controller 12, the grid plate 15, the laser cutting head 391, and the laser ranging sensor 392 are all existing technologies and will not be described in detail here; at the same time, the roller group 27 includes a horizontal plate fixedly connected to the bottom of the gantry 29 and two groups of three rollers in the front and rear that are rollingly connected to the slide rail 26. As existing technologies, they will not be described in detail here.

[0033] The following is a detailed description of the working principle of the fully automatic laser tube cutting machine.

[0034] like Figure 1-6 As shown, when the laser cutting head 391 needs to be adjusted forward and backward in the horizontal direction, the PLC controller 12 will issue a command to start the motor 1 22. The output end of the motor 1 22 drives the pulley 1 23 to rotate. Since the pulley 1 23 and the pulley 2 24 are connected by a belt, the pulley 2 24 will also rotate with the pulley 1 23. When the pulley 2 24 rotates, the rotating shaft 1 fixed on its right side also rotates, thereby causing the gear 1 25 fixed on the right end of the rotating shaft 1 to start rotating. During the rotation of the gear 1 25, according to the gear According to the meshing transmission principle with the rack, the fixed frame 21 will move back and forth in the horizontal direction along the slide rail 26. At the same time, the right side of the fixed frame 21 is fixedly connected to the bottom of the left wall of the gantry 29 through the L-shaped fixed plate 28. Therefore, when the fixed frame 21 moves horizontally, the gantry 29 will also move back and forth in the horizontal direction. The left and right sides of the bottom of the gantry 29 are movably connected to the slide rail 26 through the roller group 27, ensuring the smooth movement of the fixed frame 21 and the gantry 29, thereby driving the cutting head to achieve preliminary positioning in the horizontal direction.

[0035] When the laser cutting head 391 needs to be adjusted left and right in the horizontal direction, the PLC controller 12 will control the motor 293 to start. After the motor 293 is started, its output end drives the pulley 3 294 to rotate, and through the belt transmission, the pulley 4 295 also rotates. When the pulley 4 295 rotates, the rotating shaft 2 rotates accordingly, and then drives the gear 2 297 fixed to the front side of the rotating shaft 2 to rotate. Since the gear 2 297 and the rack 2 296 are meshed and connected, during the rotation of the gear 2 297, the fixed frame 2 292 will rotate according to the meshing transmission principle of the gear and the rack. , it moves horizontally left and right along the gantry 29. When the fixed frame 292 moves, the L-shaped fixed plate 298 connected thereto drives the fixed seat 299 to move left and right. At the same time, the guide rail 291 and the slider 1 290 make the fixed seat 299 more stable during the left and right movement. Through the provided cutting head horizontal positioning component 2, the horizontal position of the laser cutting head 391 can be accurately adjusted, thereby ensuring the accuracy of the cutting path, improving the cutting accuracy, making the finished size of the cut pipe more in line with the design requirements, and reducing the generation of waste due to cutting position deviation.

[0036] When it is necessary to adjust the distance between the laser cutting head 391 and the pipe to be cut, the PLC controller 12 will control the motor three 31 to start according to the information feedback from the laser ranging sensor 392. After the motor three 31 is started, it drives the screw 32 to rotate. When the screw 32 rotates, the nut 33 will move up and down along the screw 32. Since the nut 33 is fixedly connected to the lifting plate 35, and the lifting plate 35 slides on the slide rod 393 through the slider 2 34, the lifting plate 35 will move up and down along the slide rod 393 as the nut 33 moves, thereby realizing the preliminary spacing adjustment of the cutting head in the vertical direction.

[0037] When further fine-tuning of the angle or position of the laser cutting head 391 is required, the PLC controller 12 controls the motor 4 37 to start. After starting, the motor 4 37 drives the worm 38 to rotate, and the rotation of the worm 38 drives the worm gear 39 to rotate. When the worm gear 39 rotates, the connecting block 390 rotates accordingly, thereby changing the position and angle of the laser cutting head 391 and the laser ranging sensor 392, thereby achieving real-time dynamic adjustment of the distance between the laser cutting head 391 and the pipe to be cut, as well as the cutting angle. Throughout the cutting process, various components work together. Through the precise control of the PLC controller 12, the position, distance, and angle of the laser cutting head 391 are continuously adjusted, thereby achieving accurate and efficient cutting of the pipe. The real-time dynamic cutting head distance adjustment component 3 is provided, so that the device can perform fine engraving or localization on the pipe surface, thereby flexibly meeting these diverse cutting requirements and enhancing the functional versatility of the fully automatic laser pipe cutting machine. At the same time, reasonable adjustment of the distance between the laser cutting head 391 and the pipe to be cut can allow the laser energy to act more fully on the pipe, accelerate the cutting speed, and thus improve the overall cutting efficiency.

[0038] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
