Description

Technical Field

[0001] This utility model relates to the field of flame cutting machine technology, and more specifically, to a height-adjustable flame cutting machine. Background Technology

[0002] Flame cutting works on the principle of metal combustion at high temperatures. Using fuels such as acetylene, a mixture of gas and oxygen is ignited in a nozzle to create an extremely high-temperature flame, reaching temperatures of up to 3300°C (6000°F), sufficient to melt or oxidize most metals. During flame cutting, the metal workpiece is placed on a worktable according to a pre-designed template or computer-aided design (CAD) file. The operator uses a handheld cutting nozzle to focus the flame onto the metal surface and then controls the nozzle's movement to cut the metal along a pre-defined contour. Because the metal oxidizes at high temperatures, and oxygen is simultaneously supplied through the cutting nozzle, the metal surface is oxidized and melted, ultimately forming the desired cut shape.

[0003] Patent CN214558110U discloses a flame cutting machine, including a moving trolley and a torch assembly. The moving trolley includes an active part and a driven part that are hinged together. The active part is equipped with a drive assembly and track wheels. The track wheels are located on both sides of a track and are driven synchronously by the drive assembly. The drive assembly includes a servo motor, which is connected to the track wheels via a matching worm gear and a worm wheel. The torch assembly is mounted on the active part via an adjustment frame. By using a trolley structure with a central hinge, the moving trolley can adapt to pipes of different diameters. Combined with the structure of synchronous drive by dual active wheels, the driving torque is large and the operation is smooth. The use of a servo motor in the drive motor ensures constant torque transmission and eliminates slippage caused by its own weight during upward or downward movement.

[0004] Although this device offers many benefits, it still has the following drawbacks: While the flame cutting machine can eliminate slippage caused by its own weight during upward or downward movement, the varying thicknesses and shapes of workpieces mean that the cutting flame cannot be maintained at the optimal position on the workpiece surface. Inappropriate distance between the cutting flame and the workpiece surface can lead to rough and uneven cut surfaces, such as excessive trailing, backward offset of the cut lines with varying degrees of concavity, or excessive lead-out of the cut lines on the upper half and lower edge of the cut surface. This not only affects the appearance quality of the workpiece but may also impact the processing results of subsequent steps. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] A height-adjustable flame cutting machine includes a base plate 1, four symmetrically distributed support seats 10 fixedly connected to the top of the base plate 1, an operating table 2 fixedly connected to the top of the four support seats 10, a mounting frame 9 above the operating table 2, and a flame cutting machine body 4 inside the mounting frame 9. It also includes:

[0029] The height adjustment components, which consist of four sets and are located inside the corresponding support bases 10, are used to adjust the height of the mounting bracket 9, thereby adjusting the height of the flame cutting machine body 4.

[0030] Two sets of drive components, each located on the outer surface of two support bases 10 on the same side, are used to drive the height adjustment components, thereby adjusting the flame of the flame cutting machine body 4 by adjusting the height of the mounting bracket 9.

[0031] Furthermore, the height adjustment assembly includes a guide rail 3, a connecting block 11, and a guide column 14. The support base 10 has two symmetrically distributed guide columns 14 internally connected. The top of the two guide columns 14 is fixedly connected to the connecting block 11. The top of the two connecting blocks 11 on the same side is fixedly connected to the guide rail 3. The mounting bracket 9 is slidably connected to the two guide rails 3. In this way, the connecting block 11 will move up and down along the guide column 14, thereby driving the guide rail 3 and the mounting bracket 9 to move up and down, ultimately realizing the adjustment of the height of the flame cutting machine body 4.

[0032] Furthermore, the height adjustment assembly also includes a first link 13, a connecting seat 15, and a second link 17. The second link 17 is rotatably connected to the outer surface of the connecting block 11, and the first link 13 is rotatably connected to the end of the second link 17. The first link 13 and the second link 17 are arranged in a V-shape. The connecting seat 15 is fixedly connected to the inner wall of the support base 10. The connecting seat 15 is rotatably connected to the end of the first link 13. The rotation of the rotating block 16 will drive the first link 13 to move. Since the first link 13 and the second link 17 are arranged in a V-shape, and they are rotatably connected to each other and to the connecting block 11 and the connecting seat 15, the movement of the first link 13 will drive the second link 17 and the connecting block 11 to move together.

[0033] Furthermore, a rotating block 16 is rotatably connected to the inner wall of the support base 10. The rotating block 16 is rotatably connected to the outer surface of the first connecting rod 13. Therefore, when the pulley 7 rotates, the rotating block 16 will also rotate.

[0034] Furthermore, the drive assembly includes a mounting plate 5, a drive motor 6, pulleys 7, and a belt 8. Pulleys 7 are rotatably connected to the outer surfaces of both support bases 10, and a belt 8 is sleeved between the two pulleys 7. The mounting plate 5 is fixedly connected to the outer surfaces of both support bases 10, and the drive motor 6 is fixedly mounted on the outer surface of the mounting plate 5. The output end of the drive motor 6 passes through the mounting plate 5 and is fixedly connected to the adjacent pulley 7. The two pulleys 7 are fixedly connected to corresponding rotating blocks 16. The outer surfaces of both support bases 10 are rotatably connected to pulleys 7, and these two pulleys 7 are connected by a belt 8 to form a transmission system. The mounting plate 5 is also fixedly connected to the outer surfaces of both support bases 10, and the drive motor 6 is fixedly mounted on the outer surface of the mounting plate 5. The output end of the drive motor 6 passes through the mounting plate 5 and is fixedly connected to the adjacent pulley 7. Therefore, when the drive motor 6 is working, it can drive this pulley 7 to rotate, and then drive the other pulley 7 to rotate via the belt 8.

[0035] Furthermore, the top of the operating table 2 is provided with four symmetrically distributed slots 12, which are used for the corresponding connecting blocks 11 to move up and down.

[0036] Furthermore, gaps are provided on both sides of the outer surfaces of the four support seats 10 to provide space for the first link 13 and the second link 17 to rotate.

[0037] Working Principle: When the operator needs to use the height-adjustable flame cutting machine, the drive assembly starts working when the height of the flame cutting machine body 4 needs to be adjusted. Pulleys 7 are rotatably connected to the outer surfaces of both support bases 10. These two pulleys 7 are connected by a belt 8, forming a transmission system. Mounting plates 5 are also fixedly connected to the outer surfaces of the two support bases 10. A drive motor 6 is fixedly mounted on the outer surface of the mounting plate 5. The output end of the drive motor 6 passes through the mounting plate 5 and is fixedly connected to the adjacent pulley 7. Therefore, when the drive motor 6 works, it can drive this pulley 7 to rotate, which in turn drives the other pulley 7 to rotate via the belt 8. Since the two pulleys 7 are respectively fixedly connected to corresponding rotating blocks 16, when the pulleys 7 rotate, the rotating blocks 16 will also rotate accordingly. The movement of the first link 13 will cause the second link 17 to move. Since the first link 13 and the second link 17 are arranged in a V-shape and are rotatably connected to each other and to the connecting block 11 and the connecting seat 15, the movement of the first link 13 will cause the second link 17 and the connecting block 11 to move together. In this way, the connecting block 11 will move up and down along the guide column 14, thereby causing the guide rail 3 and the mounting bracket 9 to move up and down, ultimately achieving the adjustment of the height of the flame cutting machine body 4. In order to ensure that the connecting block 11 can move up and down smoothly, four symmetrically distributed slots 12 are provided on the top of the operating table 2. These four slots 12 are used for the corresponding connecting blocks 11 to move up and down. The outer surfaces on both sides of the four support seats 10 are provided with gaps, which provide reserved space for the first link 13 and the second link 17 to rotate.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
