[0002] Laser tube cutting machines are high-efficiency devices used for cutting metal tubes, widely applied in various industrial processing fields such as automobile manufacturing, building structures, and furniture manufacturing. Traditional laser tube cutting machines typically feature multiple independent lifting and straightening devices to support and correct the tube's position, ensuring processing accuracy. However, because these lifting and straightening devices require separate installation and are numerous (generally 5-6 or more), assembly and debugging become difficult, leading to improper installation or insufficient accuracy, causing the equipment to fail to meet operational requirements. The large number of independent devices, complex structure, and numerous similar components pose a risk of mixed installations and increase the difficulty of later maintenance and debugging, affecting equipment stability and production efficiency. Multiple independent devices require more components and cylinders, increasing production costs. Furthermore, the dispersed structure during operation results in a slower response speed, making it difficult to meet high-efficiency processing demands. Utility Model Content

[0024] Please refer to the following: A laser tube cutting machine with an integrated auxiliary feeding, lifting, and correction device. Figure 1-4The device includes a pipe cutting machine body 100, which is used to cut pipes. The pipe cutting machine body 100 includes a frame 110 and two lifting and correction devices 200 disposed on the frame 110. The number of lifting and correction devices 200 is not limited to this embodiment. Generally, the frame 110 serves as the fixed base of the pipe cutting machine body 100. The pipe cutting machine body 100 is also provided with a feeding device for feeding materials, a fixing chuck for clamping and fixing pipes, and a cutting head for cutting pipes. These devices are usually connected to the frame 110. The lifting and correction device 200 includes a vertically movable base 210 and a lifting component and a correction component mounted on the base 210. The lifting component lifts the pipe to be processed, while the correction component clamps the pipe to correct its position. Traditional laser pipe cutting machines typically have multiple independent lifting and correction devices. However, due to issues with the number and accuracy of these devices, the final product often fails to meet requirements, affecting assembly efficiency and posing assembly risks. Currently, to ensure convenient loading and clamping and cutting accuracy during equipment operation, the total number of lifting and correction devices required is generally [number missing]. Five to six units are needed to meet the work requirements. The disadvantages of this solution are: due to the large number of units, the assembly requirements are high, and debugging and maintenance are difficult; the number of parts is large and similar, which poses a risk of mixed assembly; the cost is too high and the response speed is slow. The lifting and correction device 200 of this utility model has both lifting and correction functions, which is convenient for installation and debugging and reduces the later maintenance cost; the base 210 is equipped with a first cylinder 211 at the bottom, and the base 210 moves up and down by the drive of the first cylinder 211; the first cylinder 211 simultaneously drives the lifting component and the correction component installed on the base 210 to move up and down, reducing the use of cylinders and reducing production costs.

[0025] Furthermore, the lifting and correction device 200 is provided with a fixed plate 220 connecting the frame 110. The cylinder body of the first cylinder 211 is vertically fixed on the fixed plate 220, and the push rod of the first cylinder 211 is connected to the base 210. The fixed plate 220 is fixedly connected to the horizontal tube of the frame 110 by screws. The fixed plate 220 is provided with a horizontally extending plate structure. The cylinder 211 is fixed on the plate structure. The base 210 is located above the plate structure and is connected to the push rod of the cylinder 211. When the push rod of the cylinder 211 extends or retracts, it drives the base 210 to move up and down. The vertically arranged first cylinder 211 ensures that the lifting component and the correction component can move up and down simultaneously to lift and correct the position of the pipe to be processed, which is convenient for further processing. The lifting and correction device 200 is provided with a guide device on each side of the first cylinder 211. The number of guide devices is not limited to this embodiment. The guide device includes a guide sleeve 221 fixed on the fixed plate 220 and a guide rod 222 connected to the base 210. The guide rod 222 is embedded in the guide sleeve 221. The guide device is a piston structure. Its function is to ensure that the fixed plate 220 and the base 210 maintain parallel and stable movement during the pushing process of the first cylinder 211, and to prevent the base 210 from shifting, tilting or swaying due to uneven thrust during the up and down movement, which may lead to a decrease in processing accuracy, and to ensure that the base 210 moves stably along the predetermined path.

[0026] Furthermore, the lifting assembly includes a shaft frame 230 and a variable diameter wheel 231 rotatably mounted on the shaft frame 230. The shaft frame 230 is located on the base 210 on the side away from the correction assembly. The shaft frame 230 is provided with a rotating shaft 232 for connecting the variable diameter wheel 231. Outwardly extending rods are formed on both sides of the shaft frame 230. The two ends of the rotating shaft 232 are connected to the rods on both sides. The variable diameter wheel 231 is sleeved on the rotating shaft 232 to achieve rotation. During the loading or cutting process of the laser cutting machine, the tube often needs to be rotated for positioning. The rotation of the variable diameter wheel 231 can be synchronized with the tube. The variable diameter wheel 231 can adapt to tubes of different diameters or shapes, improving processing accuracy and efficiency. When the lifting and correction device 200 lifts the tube, the variable diameter wheel 231 can adjust the support position according to the diameter of the tube, stabilizing the center of gravity of the tube and improving the stability of the lifted tube.

[0027] Furthermore, the correction component is located on one side of the lifting component on the base 210. The correction component and the lifting component are located on opposite sides of the base 210 to avoid mutual interference and ensure that the lifting and correction device can simultaneously lift and correct the position of the pipe. The correction device includes two horizontally sliding clamps 240 and one or more second cylinders 250 that can drive the clamps 240 to slide horizontally. The base 210 is provided with a horizontal slide rail 212. The chuck 240 includes a slider 241 and a rotatable guide cylinder 242 on the slider 241. The chuck 240 can slide horizontally through the slider 241 and the slide rail 212. The top of the second cylinder 250 is connected to a drive block 260. Two connecting rods 261 are hinged on the drive block 260 and respectively connected to the two chucks 240. When the drive block 260 moves up and down, it can drive the chuck 240 to slide inward or outward. The two connecting rods 261 are rotatably connected to the slider 241. The lower ends of the two connecting rods 261 are connected to the drive block 260, and the upper ends extend outward and are connected to the slider 241. When the drive block 261 moves up and down, the two connecting rods 261 drive the two sliders 241 to move simultaneously toward each other or away from each other to clamp and correct the pipe. The guide cylinder 242 is vertically mounted on the top of the slider 241. The guide cylinder 242 includes a central support column and an outer columnar roller. The roller part can rotate horizontally in the longitudinal direction. The second cylinder 250 is vertically fixed on the base 210, which has a downwardly extending part. The base 210 has a "T" structure. The slide rail 212 is connected to the upper outer side of the base 210. The second cylinder 250 is fixedly connected to the lower outer side of the base 210. The push rod of the second cylinder 250 faces upward and is connected to the drive block 260 to ensure that the chuck 240 can be driven to move. The lifting and correction device 200 lifts the pipe through the variable diameter wheel 231 on the lifting assembly. The correction assembly clamps the pipe through two chucks 240 to correct the position of the pipe so that the chuck of the pipe cutting machine body 100 can then clamp and cut the pipe. The structure of the guide cylinder 242 allows the chuck to slide horizontally after clamping the pipe. When the chuck rotates while holding the pipe, the second cylinder 250 drives the chuck 240 to move outward and release the pipe. Before cutting, the chuck 240 clamps the pipe again to ensure stable cutting. The pipe cutting machine body 100 is equipped with a control system, which is connected to each lifting and correction device 200. This allows the pipe cutting machine body 100 to control the operation of the lifting and correction devices 200, the cutting head, the chuck, and other components through the control system. After reading the specifications of the loaded pipe, the pipe cutting machine body 100 can control the clamping force of the chuck 240 to avoid clamping too tightly or too loosely during the cutting process, thus ensuring the cutting accuracy of the pipe.
