When the sheet metal is laser-cut, the grinding device can automatically switch to the corresponding grinding mode (front or back of the sheet metal) according to the position and state of the sheet metal. Through the cooperation of the limiting device and the movable sleeve, the rotation and movement of the grinding disc are precisely controlled, avoiding manual operation, improving production efficiency and processing quality, and thus solving the problem in the background technology that additional manual or mechanical processing is required to remove burrs, which increases production costs and time.

[0015] Third, this invention, through the installation of a cleaning device, utilizes the linkage of a rack, pinion, rotating rod, and pusher block to automatically remove debris generated during the grinding process by pushing it to the waste inlet, thus avoiding the time waste and inconvenience of manual waste removal. Furthermore, this cleaning process is linked to the grinding process, ensuring that the equipment can operate continuously and efficiently without being affected by the accumulation of waste.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example 1

[0032] See Figures 1-6This embodiment provides an automated adjustable laser cutting machine, including a housing 1, a grinding device 2 mounted on the housing 1, and a connecting plate 21. A gantry crane rail conveyor body 5 is mounted on the top of the housing 1. The main function of the gantry crane rail conveyor body 5 is to drive the laser cutting head or the grinding device 2 to move back and forth along the rail. It can position the laser cutting head at different workpiece positions for precise cutting, and simultaneously, in conjunction with the grinding device 2, deliver the workpiece to the grinding area for further processing. This design ensures coordinated operation of all stages in the cutting and grinding process through the precise cooperation between the motor 28 and the rack 212. The bottom of the connecting plate 21 is fixedly connected to the connecting block 22, and the back of the connecting block 22 is rotatably connected to the first rotating rod 23 via a bearing. The back of the first rotating rod 23 is fixedly connected to the rotating block 24, and the back of the rotating block 24 is rotatably connected to the limiting rotating rod 25 via a bearing. The outer wall of the limiting rotating rod 25 is slidably connected to the movable sleeve 26, and the outer wall of the movable sleeve 26 is fixedly fitted with a grinding disc 27. The grinding disc 27 enhances the grinding effect through the linkage between the rotating block 24 and the limiting rotating rod 25. The design of the movable sleeve 26 allows the grinding disc 27 to adapt more flexibly to different workpiece shapes and sizes. By adjusting the rotation angle and pressure, it maximizes the removal of burrs and irregular surfaces. A motor 28 is fixedly connected to the front of the rotating block 24. A limiting rod 25 extends forward through the rotating block 24, with the extended end of the motor 28 fixedly connected to the extended end of the limiting rod 25. A first rotating rod 23 extends forward through the connecting block 22, with a counterweight slide rail 210 fixedly connected to its front. The counterweight slide rail 210 is cast in one piece, improving overall integrity. It has no internal interfaces, allowing for direct installation, facilitating manufacturing and maintenance. It reduces the number of parts and steps in the assembly process, lowering assembly costs and time, and reducing connection points and joints, thus reducing costs. The risk of loosening or failure between parts is reduced, the overall structural strength and stability of the components are enhanced, and the long service life of the product is improved. The counterweight slide rail 210 is slidably connected to the outer wall of the counterweight block 211, the first rotating rod 23 is fixedly sleeved with the first sprocket 29, the connecting plate 21 is fixedly connected to the front of the support plate 213, the inner wall of the housing 1 is provided with the first slide groove 214, the inner wall of the first slide groove 214 is slidably connected to the rack rod 212, the rack rod 212 and the first sprocket 29 mesh with each other, the inner wall of the rack rod 212 is slidably connected to the outer wall of the support plate 213, and the bottom of the rotating block 24 is fixedly connected to the laser cutting head. This laser cutting machine is not limited to laser cutting function, but also realizes an integrated processing solution by adding grinding, deburring, cleaning and other functional modules. In particular, the grinding section employs a complex transmission mechanism and rotation control system, enabling the equipment to not only perform efficient cutting but also automatically carry out subsequent finishing as needed, significantly improving the efficiency of the production line and the quality of the workpieces. Through the grinding device 2 on the housing 1 and the gantry crane rail conveying device body 5, the automatic adjustment and conveying of the laser cutting head are realized.The grinding device 2 is designed to allow for surface treatment of the cut workpiece to remove burrs and improve surface quality. A rack block is fixedly connected to the middle of the rack 212. The addition of the rack block enhances the meshing effect between the rack 212 and the first spur gear 29, improving transmission stability and accuracy. The design focus of the grinding device 2 is to precisely control the movement trajectory of the grinding disc 27 and to perform surface treatment on the workpiece according to its position and cutting state. Through the linkage between the rotating block 24 and the limiting rod 25, the grinding disc 27 can perform fine grinding on the workpiece surface, removing burrs and irregular surfaces from the cutting process and improving the surface quality of the workpiece.

[0033] In practical use, the above-mentioned equipment is used so that the gantry crane track conveying device body 5 drives the connecting plate 21 to move back and forth, the connecting plate 21 drives the connecting block 22 to move to the left, and the plate is cut by the laser cutting head. The driver 61 drives the top moving plate to move along the trajectory of the connecting block 22. When the gantry crane track conveying device body 5 drives the rack block at the top of the first spur gear 29 to mesh, there are only four rack blocks at the top of the rack rod 212. The first spur gear 29 drives the first rotating rod 23 to rotate, and the first rotating rod 23 drives the counterweight slide rail 210 to rotate. The heavy slide rail 210 drives the counterweight block 211 to descend, the first rotating rod 23 drives the rotating block 24 to rotate, the rotating block 24 drives the grinding disc 27 to descend, the starting motor 28 drives the limit rotating rod 25 and the movable sleeve 26 to rotate, the movable sleeve 26 drives the grinding disc 27 to rotate, and the rack rod 212 slides on the inner wall of the first slide groove 214 and slides on the outer wall of the support plate 213, so that the rack rod 212 always follows the movement of the connecting block 22, so that the connecting block 22 can perform laser cutting work on the right side of the box 1 and grind and deburr the plate on the left side of the inner wall of the box 1. Example 2

[0034] See Figures 1-9Based on Embodiment 1, a limiting device 3 is provided on the housing 1. The limiting device 3 includes a telescopic rod 32, which is fixedly connected to the front of the inner wall of the housing 1. A limiting ridge 38 is fixedly connected to the top of the telescopic rod 32. A telescopic sleeve 33 is slidably connected to the outer wall of the telescopic rod 32. The telescopic sleeve 33 is cast in one piece, which improves the overall integrity. It has no internal interfaces and can be directly installed, which facilitates production and maintenance. It reduces the number of parts and steps in the assembly process, reduces assembly costs and time, reduces connection points and joints, reduces the risk of loosening or failure between parts, and enhances the overall integrity. The structural strength and stability of the components enhance the product's long-term service life. A first limiting block 34 is fixedly connected to the front of the telescopic sleeve 33. A connecting rod 35 is fixedly connected to the top of the first limiting block 34, and a second limiting block 36 is fixedly connected to the bottom of the connecting rod 35. A third sliding groove 37 is provided on the left side of the inner wall of the housing 1. A constraint rod 31 is fixedly connected to the back of the connecting plate 21. A first limiting plate 39 is fixedly connected to the right side of the movable sleeve 26, and a second limiting plate 310 is fixedly connected to the left side of the movable sleeve 26. The components include a telescopic rod 32 and a limiting ridge 38, used for precise grinding of the sheet metal after laser cutting to ensure grinding accuracy. The second limiting block 36 is slidably connected to the inner wall of the third sliding groove 37. The constraint rod 31 extends movably through the housing 1 to the left and is slidably connected to the top of the connecting rod 35. The design of the constraint rod 31 allows the second limiting block 36 to slide freely on the inner wall of the housing 1, improving grinding accuracy. The second limiting block 36 fits into the second limiting plate 310. The addition of the limiting device 3 significantly improves the ability to precisely grind the cut workpiece. The telescopic rod 32 and the limiting ridge 38, through the telescopic sleeve 33, cooperate with the first limiting block 34 and the second limiting block 36 to ensure that the workpiece remains in the required position and horizontal line during laser cutting and grinding, avoiding uneven grinding caused by changes in workpiece position. The design of the constraint rod 31 and the connecting rod 35 further enhances the control of the workpiece position, making the entire grinding process more precise.

[0035] In specific use, when the gantry crane track conveyor body 5 drives the connecting block 22, the connecting block 22 drives the constraint rod 31 to move to the left. When the second limiting plate 310 is in contact with the second limiting block 36, the second limiting plate 310 presses the second limiting block 36 to move to the back. The second limiting block 36 drives the movable sleeve 26 to move on the outer wall of the limiting rotating rod 25. The motor 28 drives the limiting rotating rod 25 to rotate, and the limiting rotating rod 25 drives the movable sleeve 26 to rotate. The movable sleeve 26 drives the grinding disc 27 to grind the back of the cut plate. When the gantry crane track conveyor body 5 drives the connecting block 22 to move to the right, and the first limiting plate 39 and the first limiting block 34 are in contact, the first limiting block 34 presses the first limiting plate 39 to move to the front. The first limiting plate 39 drives the movable sleeve 26 to move to the back. The movable sleeve 26 moves forward, the motor 28 drives the limit rod 25 to rotate, the limit rod 25 drives the movable sleeve 26 to rotate, and the movable sleeve 26 drives the grinding disc 27 to grind the front of the cut plate. When the gantry crane rail conveyor body 5 drives the connecting block 22 to move back and forth, the constraint rod 31 drives the telescopic rod 32 and the telescopic sleeve 33 to extend and retract. The telescopic sleeve 33 drives the first limit block 34 to move back and forth, and the second limit block 36 slides in the third slide groove 37 to move back and forth, so that the first limit block 34 and the second limit block 36 always maintain the same horizontal line with the connecting block 22. The operation of this equipment relies on the cooperation of the electric slide rail 62 and the driver 61 and other automated systems, which can automatically adjust the working status of the cutting, grinding, and cleaning modules according to different needs. Especially during the grinding process, the equipment automatically adjusts the pressure and rotation speed of the grinding disc 27 according to different workpiece thickness, material characteristics, cutting depth and other factors to ensure that the surface of each workpiece can achieve the best effect. Example 3

[0036] See Figures 1-11Based on Embodiment 1, a cleaning device 4 is provided on the housing 1. The cleaning device 4 includes a rack 41, which is fixedly connected to the left side of the second limiting block 36. A second rotating rod 42 is rotatably connected to the left side of the housing 1 via a bearing. A second spur gear 43 is fixedly sleeved on the outer wall of the second rotating rod 42, and the second spur gear 43 meshes with the rack 41. A third rotating rod 45 is rotatably connected to the left side of the inner wall of the housing 1 via a bearing. A fixing rod 46 is fixedly connected to the right side of the third rotating rod 45. The fixing rod 46 is cast in one piece, which improves the overall integrity. It has no internal interfaces and can be directly installed, which facilitates manufacturing and maintenance, reduces the number of parts and steps in the assembly process, and lowers costs. This design reduces assembly costs and time, minimizes connection points and joints, lowers the risk of loosening or failure between parts, enhances the overall structural strength and stability of the components, and extends the product's long-term service life. A movable rod 47 is hinged to the right side of the fixed rod 46, and a push block 49 is hinged to the bottom of the movable rod 47. A second sliding groove 48 is provided on the left side of the inner wall of the housing 1, and a slider is slidably connected to the inner wall of the second sliding groove 48. The slider is fixedly connected to the left side of the push block 49. A third rotating rod 45 extends movably through the housing 1 to the left. The outer walls of the second rotating rod 42 and the third rotating rod 45 are connected by a sprocket and chain 44. When the sprocket and chain work together, they can effectively transmit mechanical power with high transmission efficiency. The contact method between the chain and sprocket ensures the continuity of power transmission and reduces sliding friction. Therefore, under the same conditions, the efficiency of a chain drive system is usually higher than that of belt drives and other forms, and it can withstand higher loads without easily slipping. This makes the sprocket particularly excellent in some high-load, high-torque transmission applications. It is also used to clean the grinding area after grinding, remove residues, and maintain a clean working environment. The front of the housing 1 has a waste outlet 410 to facilitate the discharge of waste generated during the cutting process and keep the cutting area clean. A moving device 6 is installed on the housing 1. The moving device 6 includes an electric slide rail 62, with a driver 61 on top of the electric slide rail 62. A moving plate is fixedly connected to the top of the driver 61, and a through hole is opened on the top of the moving plate. During grinding, debris falls through the through hole. As the grinding process continues, a large amount of debris and residue is generated. This debris not only affects the operation of the equipment but may also pollute the working environment. The cleaning device 4, through the linkage of the rack 41 and the second sprocket 43, drives a series of transmission mechanisms such as the second rotating rod 42, sprocket chain 44, and third rotating rod 45, enabling the movable rod 47 and the push block 49 to effectively clean the grinding area. The push block 49 reciprocates by sliding the slider within the second slide groove 48, discharging the waste to the waste outlet 410, thereby keeping the equipment clean and the cutting area hygienic.

[0037] In practical use, when the second limiting block 36 drives the rack 41 to move backward, the rack 41 drives the second sprocket 43 to rotate, the second sprocket 43 drives the second rotating rod 42 to rotate, the second rotating rod 42 drives the sprocket and chain 44 to rotate, the sprocket and chain 44 drives the third rotating rod 45 to rotate, the third rotating rod 45 drives the fixed rod 46 to rotate, and the fixed rod 46 drives the movable rod 47 and the push block 49 to move forward. The push block 49 slides on the inner wall of the second slide groove 48 through the slider on the left side of the push block 49, so that the push block 49 reciprocates and pushes the grinding debris out of the waste port 410.

[0038] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
