DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] One of the purposes of the present invention is to Figure 1-Figure 8 As shown, a laser cutting device for aluminum alloy door and window production is provided, including a machine body 100, a workbench 101 is provided on the surface of the machine body 100, symmetrically movable laser cutting machines 102 are provided on both sides of the top of the machine body 100, a servo rotating table 200 is provided at the center of the surface of the machine body 100, a support frame 201 is provided on the top of the servo rotating table 200, threaded holes are provided on both sides of the top of the support frame 201, a roller rod 202 is provided at the bottom of the support frame 201, a meshing gear 203 is provided on the surface of the output shaft of the servo rotating table 200, and a The limiting assembly 300 is used to fix and limit the aluminum material placed on the surface of the roller rod 202. Adjusting assemblies 400 are provided on both sides of the workbench 101. The adjusting assemblies 400 are used to push the aluminum material placed on the surface of the support frame 201 so that the two sides of the aluminum material are symmetrical with the center of the servo rotating table 200. Blocking assemblies 500 are provided on both sides of the meshing gear 203. The blocking assemblies 500 are used to block the waste materials dropped during the laser cutting of the aluminum material to prevent the waste materials from rolling off the surface of the workbench 101 and causing harm to the operators: When cutting aluminum materials, a meshing gear 203 is provided on the output shaft surface of the servo rotating table 200 to rotate, and the meshing gear 203 rotates to drive the rack to rotate. When the first rack segment 501 drives the second rack segment 502 to move horizontally, the second rack segment 502 drives the rotating gear 503 provided on both sides to rotate. During the rotation of the rotating gear 503, the baffle 504 provided on the surface of the rotating rod is driven to rotate, so that the baffle 504 at the cutting end forms an enclosure for the waste falling area, and the waste is blocked by the baffle 504 when rolling on the surface of the workbench 101, thereby avoiding the waste from falling and causing harm to the operator, thereby improving the safety of the cutting operation.

[0023] Considering that when the aluminum material is placed on the surface of the roller rod 202, when the placement position of the aluminum material is offset, when the surface is laser cut at a 45° angle by moving the laser cutting machine 102, it is easy to cause a large angle error, which affects the later welding of the aluminum material. Therefore, the limiting component 300 includes a three-way pipe 301 arranged inside the support frame 201, and water is placed inside the three-way pipe 301. Both sides of the three-way pipe 301 penetrate the side walls of the support frame 201 and push plates 303 are slidably arranged at the ends. A pressing plate 302 is provided on the top of the three-way pipe 301. By pressing the pressing plate 302, the water squeezes the push plate 303, and the push plate 303 slides on the inner wall of the three-way pipe 301. A reset spring 304 is provided between the three-way pipe 301 and the push plate 303. By pressing the pressing plate 302, the inside of the three-way pipe 301 is The water squeezes the push plate 303, and the two sides of the aluminum material placed on the surface of the roller rod 202 are adjusted and fixed by the push plate 303, and the push plate 303 is stopped from being pressed. The push plate 303 is reset by the force of the reset spring 304, and the aluminum material is placed on the surface of the roller rod 202. The water inside the three-way pipe 301 is squeezed to both sides by the pressure by pressing the pressure plate 302. The water squeezes the push plate 303 to move it on the inner wall of the three-way pipe 301. During the relative movement of the push plate 303, the positions of the two sides of the aluminum material placed on the surface of the roller rod 202 are adjusted to be parallel to the horizontal line. When the support frame 201 is rotated 45° by the servo rotating table 200, the aluminum material can be accurately cut, thereby improving the efficiency of the later processing of aluminum doors and windows.

[0024] When the aluminum material is placed on the surface of the roller rod 202, when it needs to be cut, the support frame 201 is driven to rotate by the servo rotating table 200. During the rotation process, the aluminum material is subjected to the centrifugal force and its position is easily offset, resulting in the offset of the cutting position. Secondary cutting is required, which affects the cutting efficiency. Therefore, threaded rods 305 are provided on both sides of the top of the push plate 303. The threaded rods 305 are matched with the threaded holes provided on the top of the support frame 201. An elastic member 306 is provided between the threaded rod 305 and the pressure plate 302. The elastic member 306 is fixed to the contact surface of the pressure plate 302. When the adjustment component 400 completes the adjustment of the placement position of the aluminum material, the aluminum material is placed on the servo The center of the rotating table 200 is symmetrical. By pressing the pressure plate 302, the pressure plate 302 squeezes the water inside the tee pipe 301, so that the push plate 303 provided at the end of the tee pipe 301 fixes the two sides of the aluminum material. By rotating the elastic member 306, the elastic member 306 is fixed inside the threaded groove provided on the surface of the support frame 201, the position of the pressure plate 302 is fixed, and the push plate 303 keeps clamping and fixing the center of the aluminum material. When the servo rotating table 200 drives the support frame 201 to rotate to a 45° cutting angle, the push plate 303 fixes and limits the two sides of the aluminum material, thereby avoiding the position displacement of the aluminum material due to centrifugal force during rotation, thereby improving the cutting efficiency.

[0025] When the aluminum material is placed on the surface of the roller rod 202, the aluminum material is cut by moving the laser cutting machine 102. In order to improve the cutting efficiency of the aluminum material, the adjustment component 400 includes a motor 401 arranged at the bottom of the workbench 101, and the output shaft of the motor 401 is provided with a driving gear 402. Symmetrical driven gear rods 403 are provided on both sides of the driving gear 402. Symmetrical moving plates 404 are provided on the surface of the driven gear rod 403. A column 405 is provided on the inner wall of the moving plate 404. A sliding rod 406 is slidingly provided on the inner wall of the column 405. A telescopic spring 407 is provided between the column 405 and the sliding rod 406. A limiting plate 408 is provided at the end of the sliding rod 406. A guide plate is provided at the end of the column 405. The width between the guide plates is twice that between the limiting plates 408. The driving gear 402 is driven to rotate by the output end of the motor 401, and the driven gear rods 403 provided on both sides of the driving gear 402 mesh and rotate. The movable plate 404 moves relative to the movable plate 404. During the movement, the limit plate 408 first contacts one side of the aluminum material. Since the guide plate at the end of the limit plate 408 is wider, the aluminum material can automatically move between the limit plates 408, and the limit plate 408 pushes the aluminum material until the other end of the aluminum material contacts the limit plate 408. At this time, the aluminum material squeezes the limit plate 408, so that the slide bar 406 provided at the end of the limit plate 408 slides inside the column 405, and the slide bar 406 squeezes the telescopic spring 407. When the end of the aluminum material squeezes the limit plate 408 and slides to the inner wall of the movable plate 404, the motor 401 stops rotating, and the size of the aluminum material is symmetrical with the servo rotating table 200 as the center. The servo rotating table 200 drives the support frame 201 to rotate, so that the aluminum material placed on the surface of the roller rod 202 rotates to the set angle. At this time, the two sides of the aluminum material are cut in turn by the mobile laser cutting machine 102, which can improve the cutting efficiency of the aluminum material.

[0026] During the aluminum cutting process, when the aluminum cutting is completed, the waste falls from a high altitude. Since the waste has sharp edges and corners, it is easy to roll down and cause harm to the operator. Therefore, the blocking component 500 includes a rack arranged on both sides of the meshing gear 203, the rack includes a first rack segment 501 and a second rack segment 502, the first rack segment 501 meshes and rotates with the meshing gear 203, the side wall of the second rack segment 502 is provided with a rotating gear 503, the bottom of the rotating gear 503 is provided with a rotating rod, the surface of the rotating rod is provided with a baffle 504, the tooth pattern ratio of the second rack segment 502 and the first rack segment 501 is 2:1, and the baffle 504 is close to the end The part is in an arc shape. When cutting aluminum materials, a meshing gear 203 provided on the output shaft surface of the servo rotating table 200 rotates, and the meshing gear 203 rotates to drive the rack to rotate. When the first rack segment 501 drives the second rack segment 502 to move horizontally, the second rack segment 502 drives the rotating gear 503 provided on both sides to rotate. During the rotation of the rotating gear 503, the baffle 504 provided on the surface of the rotating rod is driven to rotate, so that the baffle 504 at the cutting end forms an enclosure for the waste falling area, and the waste is blocked by the baffle 504 when rolling on the surface of the workbench 101, thereby avoiding the waste falling and causing harm to the operator.

[0027] When in use, the aluminum material is placed on the surface of the roller rod 202, and the pressure plate 302 is pressed so that the water inside the three-way pipe 301 squeezes the push plate 303, and the push plate 303 is used to adjust and fix the two sides of the aluminum material placed on the surface of the roller rod 202, and the pressing of the push plate 303 is stopped. The push plate 303 is reset by the force of the reset spring 304, and the aluminum material is placed on the surface of the roller rod 202, and the pressure plate 302 is pressed so that the water inside the three-way pipe 301 is squeezed to both sides, and the water squeezes the push plate 303 to move it on the inner wall of the three-way pipe 301. During the relative movement of the push plate 303, the position of the two sides of the aluminum material placed on the surface of the roller rod 202 is adjusted to be parallel to the horizontal line. When the support frame 201 is driven to rotate 45° by the servo rotating table 200, the aluminum material can be accurately cut, thereby improving the efficiency of the later processing of aluminum doors and windows; The aluminum material is pushed by the limit plate 408 until both sides of the aluminum material are squeezed, and the slide bar 406 provided at the end of the limit plate 408 slides inside the column 405, and the slide bar 406 squeezes the telescopic spring 407. When the end of the aluminum material squeezes the limit plate 408 and slides to the inner wall of the movable plate 404, the motor 401 stops rotating, and the size of the aluminum material is symmetrical with the servo rotating table 200 as the center. The servo rotating table 200 drives the support frame 201 to rotate, so that the aluminum material placed on the surface of the roller rod 202 is rotated to a set angle. At this time, the two sides of the aluminum material are cut in turn by the mobile laser cutting machine 102, which can improve the cutting efficiency of the aluminum material; When cutting aluminum materials, a meshing gear 203 is provided on the output shaft surface of the servo rotating table 200 to rotate, and the meshing gear 203 drives the rack to rotate. When the first rack segment 501 drives the second rack segment 502 to move horizontally, the second rack segment 502 drives the rotating gear 503 provided on both sides to rotate. During the rotation of the rotating gear 503, the baffle 504 provided on the surface of the rotating rod is driven to rotate, so that the baffle 504 at the cutting end forms an enclosure for the waste falling area, and the waste is blocked by the baffle 504 when rolling on the surface of the workbench 101, thereby avoiding the waste falling to cause harm to the operator and improving the safety of the cutting operation.

The aluminum material is adjusted twice by adjusting the assembly 400. The aluminum material is symmetrical with the servo rotating table 200 as the center. The servo rotating table 200 drives the support frame 201 to rotate, so that the aluminum material placed on the surface of the roller rod 202 rotates to a set angle. At this time, the laser cutting machine 102 is moved to cut both sides of the aluminum material in turn, which can improve the cutting efficiency of the aluminum material. S3. When the aluminum material is cut by the mobile laser cutting machine 102, the meshing gear 203 provided on the output shaft surface of the servo rotating table 200 rotates. When the meshing gear 203 rotates, it drives the blocking component 500 to rotate, so that the blocking component 500 at the cutting end forms an enclosure for the waste falling area. When the waste rolls on the surface of the workbench 101, it is blocked by the blocking component 500, thereby avoiding the waste falling to cause harm to the operator and improving the safety of the cutting operation.

9. A laser cutting method for aluminum alloy door and window production, implemented by the laser cutting device for aluminum alloy door and window production according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1, placing an aluminum material on the surface of the roller rod (202), and adjusting and fixing two sides of the aluminum material placed on the surface of the roller rod (202) by means of a limit assembly (300); S2. The aluminum material is adjusted twice by adjusting the adjustment component (400). The aluminum material is symmetrical with the servo rotating table (200) as the center. The servo rotating table (200) drives the support frame (201) to rotate, so that the aluminum material placed on the surface of the roller rod (202) rotates to a set angle. At this time, the two sides of the aluminum material are cut in sequence by moving the laser cutting machine (102), thereby improving the cutting efficiency of the aluminum material. S3. When the aluminum material is cut by the mobile laser cutting machine (102), the meshing gear (203) provided on the output shaft surface of the servo rotating table (200) rotates. When the meshing gear (203) rotates, it drives the blocking component (500) to rotate, so that the blocking component (500) at the cutting end forms an enclosure around the waste falling area. When the waste rolls on the surface of the workbench (101), it is blocked by the blocking component (500), thereby preventing the waste from falling and causing harm to the operator, thereby improving the safety of the cutting operation.
