[0022] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model.

[0023] A chuck laser tube cutting machine consists of a bed, a chuck structure that reciprocates along the length of the bed, and a laser cutting assembly 500 mounted on the bed. The chuck structure clamps and advances the tube, allowing a high-energy laser beam emitted by the laser cutting assembly 500 to process and cut the tube. However, in traditional tube cutting machines, the front and rear chucks are prone to collision during high-speed movement. This not only reduces the positioning accuracy of the cut but may also damage the chuck drive mechanism in severe cases.

[0024] Therefore, this utility model proposes an automatic material receiving and pipe cutting machine, referring to... Figures 1-5It includes a frame 100, a first guide rail 110, a gantry frame 120, a second guide rail 130, a front chuck assembly 200, a collision avoidance assembly 300, a rear chuck assembly 400, and a cutting assembly 500. The first guide rail 110 is mounted on the frame 100, the gantry frame 120 is mounted on the frame 100, and the second guide rail 130 is mounted on the side of the gantry frame 120 and perpendicular to the first guide rail 110. The cutting assembly 500 is mounted on the side of the gantry frame 120 and perpendicular to the first guide rail 110. The guide rail 130 is slidably connected. The front chuck assembly 200 and the rear chuck assembly 400 are slidably disposed on the first guide rail 110. The front chuck assembly 200 is disposed on one side of the cutting assembly 500. The anti-collision assembly 300 includes a base 310 and a buffer block 320. The base 310 is disposed on the rear chuck assembly 400. The end face of the base 310 facing the cutting assembly 500 is a limiting surface. The buffer block 320 is disposed on the limiting surface.

[0025] The frame 100 provides a stable mounting base; the first guide rail 110 provides guidance for the reciprocating movement of the front chuck assembly 200 and the rear chuck assembly 400 along the length of the bed; the second guide rail 130 provides guidance for the cutting assembly 500 to slide in a direction perpendicular to the pipe axis; the front chuck assembly 200 and the rear chuck assembly 400 cooperate to realize operations such as pipe conveying and positioning, facilitating the cutting assembly 500 to cut the pipe; the base 310 of the anti-collision assembly 300 is set on the rear chuck assembly 400, and its limiting surface cooperates with the buffer block 320. When the rear chuck assembly 400 accidentally moves at high speed towards the front chuck assembly 200, the buffer block 320 can contact the front chuck assembly 200 first. Through the buffering effect of the buffer block 320, the impact force generated by the collision is absorbed, protecting the chuck assembly. This utility model effectively avoids collisions between the front and rear chucks during high-speed movement by setting up an anti-collision component 300, ensuring cutting positioning accuracy, reducing the risk of damage to the chuck drive mechanism caused by collisions, improving the overall stability and service life of the equipment, and thus enabling stable and efficient cutting of pipes, improving processing quality and production efficiency.

[0026] During operation, the pipe is first clamped by the front chuck assembly 200 and the rear chuck assembly 400. Then, the cutting assembly 500 moves to the appropriate position under the guidance of the second guide rail 130 and uses its emitted high-energy laser beam to cut the pipe. Throughout the process, the front chuck assembly 200 and the rear chuck assembly 400 need to reciprocate along the first guide rail 110 to adjust the position of the pipe. When the rear chuck assembly 400 moves closer to the front chuck assembly 200, the buffer block 320 of the anti-collision assembly 300 will be the first to contact the object that may collide. The buffer block 320 is made of an elastic material, which can absorb and buffer the impact force generated by the collision through its own elastic deformation at the moment of contact. This gradually reduces the kinetic energy of the rear chuck assembly 400, preventing it from having a hard collision with the front chuck assembly 200 or other components. This protects the chuck assembly and related drive mechanism, ensuring that the entire pipe cutting machine can work continuously and stably, achieving efficient and precise cutting of the pipe. It should be noted that, in the initial state, the distance between the limiting surface and the end face of the front chuck assembly 200 facing the rear chuck assembly 400 is less than the maximum movable distance of the rear chuck assembly 400 on the first guide rail 110, to ensure the effective implementation of the anti-collision function. The front chuck assembly 200 and the rear chuck assembly 400 are existing technologies, and their specific structures and working principles will not be described in detail.

[0027] In one embodiment, the buffer block 320 is made of urethane. Uric acid has excellent elasticity and cushioning properties, enabling it to absorb and buffer the impact force generated by a collision when the front chuck assembly 200 and the rear chuck assembly 400 unexpectedly approach each other at high speed and are prone to collision. This prevents hard collisions, effectively ensuring cutting positioning accuracy, guaranteeing precise pipe cutting dimensions, and improving product quality.

[0028] For situations requiring cutting at different positions along the circumference of the pipe, precise operation may be difficult, affecting cutting quality. Therefore, in one embodiment, the cutting assembly 500 includes a second slider 510, a mounting bracket 520, a third slider 530, a third guide rail 540, a laser cutting head 550, a first driving device 560, and a second driving device 570. The second slider 510 is slidably connected to the second guide rail 130. The mounting bracket 520 is disposed on the second slider 510. The third guide rail 540 is vertically disposed on the mounting bracket 520. The third slider 530 is slidably connected to the third guide rail 540. The laser cutting head 550 is disposed on the third slider 530. The first driving device 560 is disposed on the gantry frame 120 and is used to drive the second slider 510 to move along the second guide rail 130. The second driving device 570 is disposed on the mounting bracket 520 and is used to drive the third slider 530 to move along the third guide rail 540. Through the sliding connection between the second slider 510 and the second guide rail 130, and the driving action of the first driving device 560, the laser cutting head 550 can move perpendicular to the pipe axis and quickly position itself to the part of the pipe that needs to be cut. The third guide rail 540, in conjunction with the connection between the third slider 530 and the laser cutting head 550, and the driving action of the second driving device 570, allows the laser cutting head 550 to be adjusted vertically, enabling cutting at different heights of the pipe, enhancing cutting flexibility and precision. This allows for cutting tasks with various complex shapes and sizes, improving cutting efficiency. Specifically, the first driving device 560 and the second driving device 570 are one of a gear and rack mechanism, a linear motor, and a ball screw mechanism.

[0029] The slider is side-mounted, and conventional lubrication methods, where oil is applied from the end of the slider, cannot ensure adequate lubrication for the upper half. Therefore, in one embodiment, the second slider 510 has an oil injection hole 511 at its top. This hole extends downwards and connects to the sliding surface within the second slider 510 that mates with the second guide rail 130. Lubricating oil can penetrate from top to bottom through the oil injection hole 511 to the sliding surfaces of both halves, ensuring comprehensive and sufficient lubrication. Compared to traditional lubrication methods, this effectively reduces localized wear caused by lubrication dead zones, keeping the friction between the slider and the guide rail at a low level and extending their service life. Preferably, the oil injection hole 511 is connected to an external centralized lubrication system, which includes an oil pump and a distributor for injecting oil into the second slider 510.

[0030] During the cutting process, the first drive device 560 is susceptible to vibration and impact, causing the cutting trajectory to deviate. Therefore, in one embodiment, the first drive device 560 includes a first gear 561, a first rack 562, and a first motor 563. The first motor 563 is mounted on the mounting bracket 520, and the first rack 562 is mounted on the gantry frame 120 and parallel to the second guide rail 130. The first gear 561 is coaxially rotatable with the drive unit of the first motor 563, and the first gear 561 meshes with the first rack 562. The meshing transmission of the gear and rack enables backlash-free power transmission, improving the positioning accuracy of the cutting assembly 500. The gear and rack structure has high rigidity, effectively resisting vibration and impact during the cutting process and maintaining the stable operation of the cutting assembly 500, making it particularly suitable for high-speed cutting and thick-walled pipe processing.

[0031] Insufficient lubrication is prone to occur during manual lubrication intervals, leading to accelerated tooth surface wear and shortening the service life of the gear rack. Therefore, in one embodiment, the first drive device 560 further includes a felt wheel 564 and a shaft 565. The shaft 565 is mounted on the mounting bracket 520, and the felt wheel 564 is rotatable relative to the shaft 565, with the felt wheel 564 abutting against the tooth surface of the first rack 562. The felt wheel 564, abutting against the rack tooth surface, continuously releases lubricating oil, maintaining tooth surface lubrication and reducing frictional resistance. During its movement following the cutting assembly 500, the felt wheel 564 effectively adsorbs and removes metal debris, dust, and other impurities from the rack tooth surface, preventing impurities from entering the meshing area and extending the service life of the gear rack. Preferably, the felt wheel 564 is connected to an external centralized lubrication system, which includes an oil pump and a distributor for injecting oil into the felt wheel 564.

[0032] For longer pipes, sagging may occur during the cutting process due to a lack of central support. Therefore, in one embodiment, the automatic pipe receiving and cutting machine further includes a follow-up support assembly 600. The follow-up support assembly 600 includes a fixed plate 610, a fourth slider 620, a clamping device 630, a support device 640, a second motor 650, a second gear, and a fourth guide rail 660 and a second rack arranged parallel to the fixed plate 610. The fixed plate 610 is disposed on the frame 100. The fourth slider 620 is slidably connected to the fourth guide rail 660. The second motor 650 is disposed on the fourth slider 620. The second gear is coaxially rotatably disposed with the drive unit of the second motor 650. The second rack meshes with the second gear. The second motor 650 drives the fourth slider 620 to reciprocate along the fourth guide rail 660. The support device 640 is disposed on the top surface of the fourth slider 620 and is used to support the bottom of the pipe. The clamping device 630 is disposed on the fourth slider 620 and is used to center the pipe. The support device 640 provides effective support to the bottom of the pipe at all times, preventing the pipe from sagging in the middle due to its long length during cutting and ensuring the straightness of the pipe in the horizontal direction. The clamping device 630 centers the pipe, ensuring it maintains a precise axial center position and a more accurate relative position to the cutting assembly 500, further optimizing the cutting effect and reducing cutting errors caused by pipe eccentricity. Specifically, the support device 640 and clamping device 630 are existing technologies, and their specific structures and working principles will not be described in detail.

[0033] During the cutting process, the end of the pipe may sag or bend due to its own weight. Therefore, in one embodiment, the automatic pipe receiving and cutting machine further includes a receiving assembly 700. The receiving assembly 700 includes a receiving frame 710, a flip plate 720, a first cylinder 730, and a receiving bracket 740 that can move up and down along the receiving frame 710. The first cylinder 730 is mounted on the receiving bracket 740. One end of the flip plate 720 is hinged to the receiving bracket 740, and the other end of the flip plate 720 is hinged to the drive part of the first cylinder 730. During the cutting process, the vertical movement of the receiving bracket 740 and the horizontally positioned flap 720 provide support to the bottom of the pipe, effectively counteracting the influence of the pipe's own weight and preventing problems such as sagging and deformation. This ensures that the pipe maintains good straightness and stability during cutting. When unloading, the retraction action of the first cylinder 730 drives the flap 720 to rotate downward along the hinge, using the pipe's own weight to unload the pipe, shortening the unloading time and improving production efficiency.

[0034] Sliding friction between the pipe and the flip plate 720 can cause scratches and dents. Therefore, in one embodiment, the flip plate 720 is provided with a plurality of rollers 721 spaced apart along the length of the first guide rail 110. The rolling of the rollers 721 replaces sliding friction, avoiding scratches on the pipe surface and improving the surface quality of the product; the rolling friction resistance is small, which can increase the pipe feeding speed and reduce the required driving power, thus reducing equipment energy consumption; for large-diameter or heavy pipes, the roller structure can evenly distribute the force, prevent local deformation, and ensure the geometric accuracy of the pipe.

[0035] The length of the tail material may not be sufficient for simultaneous cutting under the clamping of the front chuck assembly 200 and the rear chuck assembly 400. Therefore, in one embodiment, the receiving assembly further includes a clearance plate and a second cylinder, the second cylinder being disposed on the bottom surface of the flip plate, one end of the clearance plate being hinged to the flip plate, and the other end of the clearance plate being hinged to the drive unit of the second cylinder. When cutting long materials, the second cylinder drives the clearance plate to a horizontal position, which, together with the flip plate, supports the bottom surface of the pipe and receives the material. This increases the support area and distributes the weight of the long material more evenly, effectively preventing the long material from sagging or swaying due to insufficient support. In the tail material cutting stage, since no secondary processing is required in the pipe length processing, only the tail of the pipe needs to be cut off to meet the processing requirements. The rear chuck assembly 400 releases its clamping grip, and the front chuck assembly 200 moves the pipe closer to the receiving assembly, so that the tail of the pipe is out of the working area of ​​the cutting assembly. At the same time, the second cylinder retracts, causing the clearance plate to rotate along the hinge to avoid collision between the front chuck assembly 200 and the receiving assembly. This ensures that the cutting assembly can smoothly cut the tail material, guaranteeing the continuity and accuracy of the tail material cutting operation, reducing the risk of equipment damage, and improving the reliability of equipment operation and overall production efficiency.
