Description

Technical Field

[0001] This invention relates to the field of metal pipe processing equipment technology, specifically a pipe lifting and unloading device for a laser pipe cutting machine. Background Technology

[0002] In the field of modern industrial processing, laser cutting technology has become a core means of metal pipe processing and is widely used in many industries such as automobile manufacturing and aerospace. This has placed higher demands on the precision, efficiency and safety of pipe cutting.

[0003] Currently, the existing lifting and feeding equipment of the laser tube cutting machine for metal tubes has many shortcomings: the feeding process lacks stable support and a precise feeding mechanism, which easily causes tube deviation and affects the cutting accuracy; the clamping components have poor flexibility and cannot be adapted to tubes of different lengths and placement angles, and most of them are rigid clamps, which are easy to scratch the surface of the tubes. At the same time, it is difficult to solve the problems of material jamming and deviation caused by tube eccentricity and bending.

[0004] Dust, intense light, and harmful gases generated during the cutting process can easily spill out, threatening the safety of operators and contaminating the laser cutting head, affecting processing accuracy. In addition, finished pipes are often dropped directly during unloading, which can easily cause surface scratches, and twisting and jamming can easily occur during transportation, reducing processing efficiency and the yield of qualified products.

[0005] Therefore, there is an urgent need for a lifting and unloading device that can achieve precise feeding, flexible clamping, safety protection, and stable unloading, and adapt to diverse processing needs, so as to solve the above-mentioned defects of the existing technology. Summary of the Invention

[0007] To achieve the above objectives, the present invention provides the following technical solution: a tube lifting and unloading device for a laser tube cutting machine, comprising a machine tool, a cutting head, a tube support bracket, an automatic feeding component, and an auxiliary placement component. The machine tool serves as the core support of the device, and its top is provided with a V-shaped feeding groove adapted to the tube. Wear-resistant and anti-slip pads are embedded in the groove to stably support metal tubes of various specifications. The built-in servo feeding mechanism enables uniform and precise feeding of the tube. The cutting head compartment is fixedly installed in the upper middle part of the machine tool. It integrates a laser cutting head and cooling pipes. The laser cutting head can move up and down and left and right along the slide rail inside the cutting head compartment. In conjunction with the feeding action of the machine tool, it can complete complex processing such as opening, cutting and beveling of the pipe, and adapt to the diverse processing needs of pipes of different specifications. The internal structure of the cutting head chamber is fully enclosed and protected. The side walls of the chamber are made of double-layer soundproof and dustproof panels, and the opening is equipped with elastic sealing strips, which can effectively prevent dust, strong light and harmful gases generated during the cutting process from escaping. This not only ensures the personal safety of the operators, but also prevents dust from adhering to the surface of the laser cutting head and affecting the cutting accuracy. The top of the pipe support bracket is equipped with a buffer pad to bear the weight of the pipe and the slight vibration during processing, effectively buffering the transmission of vibration and ensuring that the overall equipment does not deviate or shake, providing stable auxiliary support for the automatic feeding component. The automatic feeding component is used to automatically receive and transport the finished pipe after cutting, so as to prevent the finished pipe from falling directly and causing surface scratches. A sliding rod is fixedly connected to the inner side of the machine tool, and an auxiliary placement component is movably connected to the outer surface of the sliding rod. The auxiliary placement component can slide freely along the sliding rod to adapt to the clamping requirements of pipes of different lengths. The auxiliary placement component is used to solve the problems of jamming and deviation caused by pipe eccentricity and bending during pipe feeding or unloading. Through the flexible clamping design of the pipe, combined with the built-in pressure sensor to provide real-time feedback of clamping force, it can automatically adjust the clamping force to avoid scratches on the pipe surface caused by rigid limit and protect the appearance quality of the pipe. The auxiliary placement component includes a driving component and a fixing component. The driving component is used to drive the entire auxiliary placement component to rotate smoothly to adapt to the pipe clamping requirements at different placement angles. The fixing component is connected and installed on the top of the driving component. When the driving component rotates, it will drive the fixing component to rotate synchronously. By using the forward extension and folding contraction action of the fixing component, the pipe can be quickly grabbed and the placement position can be adjusted, so as to achieve precise alignment and stable clamping of the pipe, and further improve the efficiency and stability of feeding and unloading.

[0025] Example 2: Based on Example 1, as follows Figure 3-8 As shown, the driving component 51 includes a sliding block 511. The inner groove at the bottom of the sliding block 511 is movably connected to the outer surface of the sliding rod 14.

A swing rod 522 is provided on both sides of the top of the first driving block 521, and the top two sides of the first driving block 521 are movably connected to the bottom of the swing rod 522. A telescopic rod 523 is provided on the inner side of the top of the two swing rods 522, and the inner side of the top of the two swing rods 522 is movably connected to both sides of the telescopic rod 523.

[0028] The top of the telescopic rod 523 is provided with a second driving block 524, and the top of the telescopic rod 523 is fixedly connected to the rear end of the second driving block 524. The top of the second driving block 524 is provided with a polygonal plate 525, and the top of the second driving block 524 is movably connected to the bottom of the polygonal plate 525. The first driving block 521 first drives the swing rod 522 to swing back and forth. Then the telescopic rod 523 extends and cooperates, driving the second driving block 524 to move. The second driving block 524 then drives the polygonal plate 525 to rotate, so that the clamping component 526 can flexibly change the gripping angle, which can adapt to pipes with different placement postures, realize the rapid gripping and precise alignment of pipes, and improve the feeding and unloading efficiency. The polygonal plate 525 is provided with clamping components 526 at both the top and bottom ends, and the top and bottom ends of the polygonal plate 525 are respectively connected to the inner side of the clamping component 526.

[0029] The clamping assembly 526 includes two gears 5261. Each of the outer surfaces of the two gears 5261 is provided with a first semi-circular gear 5262, and the outer surfaces of the two gears 5261 are meshed with the outer surfaces of the first semi-circular gears 5262.

The other side of each movable rod 5265 is movably connected to the outer surface of the polygonal plate 525. Each of the two clamping blocks 5264 has a flexible clamping claw 5266 on the inner side of its top. The inner side of the top of each clamping block 5264 is fixedly connected to the inner side of the flexible clamping claw 5266. Through the meshing transmission of gear 5261, first semi-circular gear 5262 and second circular gear 5263, the clamping block 5264 can be driven to open and close smoothly. Then, the flexible clamping claw 5266 on the inner side of the top of the clamping block 5264 can realize the flexible clamping of the pipe. With the pressure sensor 53 built into the auxiliary placement component 5, the clamping force is fed back in real time and the clamping force is automatically adjusted. This not only avoids the rigid limit from scratching the surface of the pipe and protecting the appearance quality of the pipe, but also solves the problems of jamming and deviation caused by pipe eccentricity and bending, and improves the clamping stability.

[0031] The automatic feeding assembly 4 includes a guide rail 41, a transmission chain 42, and pneumatic rollers 43. The transmission chain 42 drives the pneumatic roller shafts 43 to rotate synchronously, ensuring that all pneumatic rollers 43 rotate at the same speed, thus preventing the pipe from twisting or jamming during movement.

[0032] The working principle of this invention is as follows: Firstly, machine tool 1 is used as the core load-bearing component. The V-shaped feeding groove 11 on its top is embedded with wear-resistant and anti-slip pads 12 to stably support metal pipes of various specifications. The servo feeding mechanism 13 built into the machine tool 1 is started to achieve uniform and precise feeding of the pipe. At the same time, the buffer pad 31 on the top of the pipe support bracket 3 bears the weight of the pipe and the slight vibration during processing, effectively buffering the transmission of vibration and ensuring that the overall operation of the equipment does not deviate or shake, providing stable auxiliary support for the automatic feeding component 4. An auxiliary placement component 5 is movably connected to the outer surface of the sliding rod 14 fixedly connected to the inner side of the machine tool 1. The auxiliary placement component 5 can slide freely along the sliding rod 14 to adapt to the clamping requirements of pipes of different lengths. The auxiliary placement component 5 includes a driving component 51 and a fixing component 52. The driving component 51 is used to drive the entire auxiliary placement component 5 to rotate smoothly to adapt to the clamping requirements of pipes at different placement angles. After the motor 516 in the driving component 51 is started, it will drive the fixing plate 515 and the fixing component 52 above it to rotate smoothly. At the same time, the sliding wheel 514 at the bottom of the fixing plate 515 not only provides stable support for the fixing plate 515 and the fixing component 52, but also enhances the flexibility during rotation, avoids jamming, and ensures smooth and stable clamping action. The movable connection between the sliding block 511 and the sliding rod 14 drives the entire auxiliary placement component 5 to slide along the sliding rod 14 to adapt to pipes of different lengths. The fixing component 52 is connected to the top of the fixing plate 515 of the driving component 51. When the driving component 51 rotates, it will synchronously drive the fixing component 52 to rotate. The first driving block 521 will first perform the first step of driving, driving the swing rods 522 movably connected to its top two sides to swing back and forth. Then, the telescopic rods 523 movably connected to the top inner side of the two swing rods 522 extend and cooperate, driving the second driving block 524 fixedly connected to the top of the telescopic rod 523 to move. The second driving block 524 then drives the polygonal plate 525 movably connected to its top to rotate, so that the clamping components 526 connected to the upper and lower ends of the polygonal plate 525 can flexibly change the gripping angle to adapt to pipes with different placement postures, and realize the rapid gripping and precise alignment of the pipes. The clamping assembly 526 drives the clamping block 5264, which is movably connected to the other end of the clamping block 5264, to open and close smoothly through the meshing of the gear 5261, the first semi-circular gear 5262 and the second circular gear 5263. The other end of the movable rod 5265, which is movably connected to both sides of the clamping block 5264, is movably connected to the outer surface of the polygonal plate 525 to assist the clamping block 5264 in moving smoothly. The flexible clamping claw 5266, which is fixedly connected to the inner side of the top of the clamping block 5264, realizes the flexible clamping of the pipe. With the help of the pressure sensor 53 built into the auxiliary placement assembly 5, the clamping force is fed back in real time and the clamping force is automatically adjusted to solve the problem of jamming and deviation caused by the pipe eccentricity and bending during the pipe feeding or unloading process. At the same time, it avoids the rigid limit to scratch the surface of the pipe and protects the appearance quality of the pipe. After the pipe is fed into place, the cutting head chamber 2, which is fixedly installed in the middle of the machine tool 1, begins to work. The laser cutting head 21 integrated inside can move up and down and left and right along the slide rail inside the cutting head chamber 2. In coordination with the feeding action of the machine tool 1, it completes complex processing such as opening, cutting, and beveling of the pipe, adapting to the diverse processing needs of pipes of different specifications. The cutting head chamber 2 adopts a fully enclosed protective structure. The side wall of the chamber is made of double-layer sound insulation and dustproof plate 23. The opening is equipped with an elastic sealing strip 24 to prevent dust, strong light and harmful gases generated during the cutting process from escaping, ensuring the personal safety of the operator and avoiding dust adhering to the surface of the laser cutting head 21 and affecting the cutting accuracy. During the cutting process, the cooling pipe 22 inside the cutting head chamber 2 provides cooling for the laser cutting head 21 to ensure stable operation of the cutting head. After the pipe is cut, the automatic feeding component 4 is started. Its guide rail 41, together with the transmission chain 42, drives the pneumatic roller 43 to rotate synchronously, ensuring that all pneumatic rollers 43 rotate at the same speed. It automatically receives and transports the finished pipe, avoiding the finished pipe from falling directly and causing surface scratches. At the same time, it prevents the pipe from twisting or jamming during movement, ensuring a smooth unloading process and completing the entire process of lifting, cutting and unloading the metal pipe.
