As a result, they are gradually replacing traditional metal cutting equipment. Integrated plate and tube laser cutting machines typically include a plate cutting mechanism, a tube cutting mechanism, and a laser cutting mechanism.

[0003] Patent application CN219094036U discloses a tube cutting mechanism for an integrated plate and tube laser cutting machine, including a mounting base. The top of the mounting base is provided with a movable rear chuck assembly for fixing the tube. The right end of the top of the mounting base is provided with a front chuck assembly for clamping the tube. The top of the mounting base is provided with a transverse drive assembly.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] The tube cutting mechanism of the integrated plate and tube laser cutting machine disclosed in this utility model is mainly used in the scenario of integrated plate and tube laser cutting machine.

[0024] Reference Figures 1 to 4 The tube cutting mechanism of the integrated plate and tube laser cutting machine includes: a mounting plate 1, connecting plates 2 are equidistantly arranged on the top of the mounting plate 1, a connecting block 3 is fixedly connected to one side of the connecting plate 2, a mounting frame 4 is fixedly connected to one side of the connecting block 3, a clamping assembly is provided inside the mounting frame 4, a groove 10 is opened on the top of the mounting plate 1, a lead screw 11 is rotatably connected inside the groove 10, a moving block 13 is fixedly connected to the bottom of the connecting plate 2, the inside of the moving block 13 is threadedly connected to the outside of the lead screw 11, a motor 12 is provided on one side of the mounting plate 1, one end of the output shaft of the motor 12 is fixedly connected to one end of the lead screw 11, and a support assembly is provided on the top of the mounting plate 1;

[0025] The clamping assembly includes a first fixing plate 5, which is fixedly connected to the bottom of the inner wall of the mounting frame 4. A telescopic rod 6 is provided at the bottom of the mounting frame 4, and the bottom of the output shaft of the telescopic rod 6 extends into the interior of the mounting frame 4 and is fixedly connected to a second fixing plate 7.

[0026] The second fixed plate 7 is fixedly connected to both sides of the slider 8, and the inner wall of the mounting frame 4 is provided with both sides of the sliding groove 9. The outer side of the slider 8 is slidably connected to the inside of the sliding groove 9.

[0027] Both the bottom of the first fixing plate 5 and the top of the second fixing plate 7 have arc-shaped surfaces.

[0028] In the above technical solution, considering that the device uses the front chuck assembly to fix and clamp the inserted pipe, it is inconvenient to flexibly fix the plate and limits the processing range. To solve this problem, the specific operation is as follows: Before cutting the plate or pipe, it needs to be fixed. Using the clamping assembly, when fixing the plate, first adjust the height of the support assembly to be flush with the first fixing plate 5, place the plate on the support assembly, start the motor 12 to drive the lead screw 11, and at the same time drive the moving block 13, connecting plate 2, connecting block 3 and mounting frame 4 to move, clamping the plate from both sides, with one end of the plate placed on the first fixing plate 5. Then, the telescopic rod 6 is activated to move the second fixing plate 7 downwards to press against the surface of the plate, forming a clamp for cutting. When fixing the pipe, the telescopic rod 6 is activated to make the second fixing plate 7 fit against the first fixing plate 5, so that the two fixing plates extend into the pipe opening. Then, the telescopic rod 6 is retracted to move the second fixing plate 7 upwards. Using the arc surface, the two fixing plates are spread apart, thereby fixing and cutting the pipe. This allows for flexible clamping of plates and pipes, no longer limited by a single clamping method, improving the versatility of the equipment. Providing stable clamping ensures that the cutting head is kept in the correct position, improving the accuracy and consistency of cutting.

[0029] Reference Figures 1 to 4In a preferred embodiment, the support assembly includes fixed blocks 14, which are equidistantly fixed to the top of the mounting plate 1. A sliding rod 15 is provided between one side of the fixed blocks 14, and a mounting block 16 is slidably connected to the outer side of the sliding rod 15. The bottom of the mounting block 16 is slidably connected to the top of the mounting plate 1. A threaded rod 17 is rotatably connected to the top of one mounting block 16, and a connecting rod 18 is provided to the top of the other mounting block 16. A support plate 19 is provided to the top of the mounting plate 19, and mating plates 20 are fixedly connected to both sides of the support plate 19. The outer side of the threaded rod 17 is threadedly connected to the inside of one of the mating plates 20, and the outer side of the connecting rod 18 is slidably connected to the inside of the other mating plate 20. By moving the two sets of moving blocks 13, the support distance can be adjusted, and the plate or pipe can be placed on the support plate 19. Then, the height of the support plate 19 can be adjusted by rotating the threaded rod 17, which facilitates the clamping assembly to fix it. At the same time, the plate or pipe can be supported during the cutting process, avoiding the cutting accuracy problem of the pipe during laser cutting.

[0030] Reference Figures 1 to 4 In a preferred embodiment, both the telescopic rod 6 and the motor 12 are electrically connected to an external controller;

[0031] Working principle: Before cutting sheet metal or pipe, it needs to be fixed. Using the clamping assembly, the support distance is adjusted by moving two sets of moving blocks 13 to place the sheet metal or pipe on the support plate 19. Then, the threaded rod 17 is rotated to adjust the height of the support plate 19 until it is flush with the first fixing plate 5. The sheet metal is then placed on the support plate 19. The motor 12 is started, driving the lead screw 11, which in turn moves the moving blocks 13, connecting plate 2, connecting block 3, and mounting frame 4, clamping the sheet metal from both sides. The end is placed on the first fixed plate 5, and then the telescopic rod 6 is activated to move the second fixed plate 7 downward to abut against the surface of the plate, forming a clamp for cutting. When fixing the pipe, the telescopic rod 6 is activated to make the second fixed plate 7 fit against the first fixed plate 5, so that the two fixed plates extend into the pipe opening. Then the telescopic rod 6 is retracted to move the second fixed plate 7 upward. Using the arc surface, the two fixed plates are spread out, thereby fixing and cutting the pipe.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
