Description

Technical Field

[0001] The utility model relates to the technical field of automatic height adjustment, in particular to a height adjustment device for a flame cutting machine. Background Art

[0002] The height adjustment device on the flame cutting machine plays an important role in improving cutting quality and efficiency. It ensures the optimal distance between the cutting gun and the workpiece during the flame cutting process by accurately adjusting the distance from the cutting gun to the workpiece, thereby avoiding the reduction of cutting quality or material waste caused by improper distance. The height adjustment device can not only sense the height change of the workpiece surface and adjust the cutting gun position, but also adapt to workpieces of different shapes and thicknesses to achieve efficient and accurate cutting. Therefore, the height adjustment device is an indispensable part of the flame cutting machine, which ensures the stability and reliability of the cutting process and improves the overall production efficiency.

[0003] The existing height adjustment device includes a height adjustment ring, which is installed on the flame cutting machine. At the same time, the height adjustment ring is connected to a capacitor height controller, which can accurately measure the distance from the height adjustment ring to the cutting gun or the workpiece through the capacitor on the height adjustment ring. In this way, the capacitor height controller can maintain a stable height between the cutting gun and the workpiece, thereby ensuring that the flame cutting machine performs accurate and smooth cutting operations.

[0004] However, in actual operation, when the flame cutting machine is cutting and perforating, a large amount of cutting slag splashes often occur, and these splashing cutting slags often adhere to the height adjustment ring, thus affecting the normal operation of the height adjustment ring and even causing it to fail. Summary of the invention

[0005] The utility model aims at solving the problem that when a flame cutting machine is cutting and perforating, splashing cutting slag may cause failure of a height adjustment ring, and provides a height adjustment device for a flame cutting machine, which can prevent splashing cutting slag from causing failure of the height adjustment ring when the flame cutting machine is cutting and perforating.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is a height adjustment device for a flame cutting machine, including a mounting frame, the mounting frame can be fixed on the flame cutting machine, a cylinder is fixed on the mounting frame, a connecting block is fixed on the piston rod of the cylinder, a height adjustment ring is fixed on the connecting block, and a capacitor height controller is connected to the height adjustment ring. By controlling the extension and retraction of the piston rod of the cylinder, the lifting and lowering of the height adjustment ring can be controlled. After the capacitor height controller adjusts the height of the cutting gun through the capacitor on the height adjustment ring, the height adjustment ring is raised by controlling the cylinder, and then the flame cutting machine is controlled to cut and perforate. At this time, the splashing cutting slag will not adhere to the height adjustment ring, and will not cause the height adjustment ring to fail.

[0007] Preferably, the mounting frame comprises a fixing plate, the fixing plate is arranged in a Z shape, and a fixing hole is arranged on the fixing plate. By installing bolts in the fixing holes, the mounting frame can be firmly fixed on the flame cutting machine to ensure the stability and safety of the operation.

[0008] Preferably, two fixing holes are provided, and the two fixing holes are evenly distributed along the horizontal direction. The two fixing holes can more effectively enhance the stability of the mounting frame.

[0009] Preferably, the fixing hole is set in an oblong shape, and the length direction of the fixing hole is parallel to the horizontal direction. The fixing hole is set in an oblong shape, which allows the position of the mounting frame to be easily fine-tuned during the installation process, thereby ensuring the accuracy of the installation.

[0010] Preferably, a U-shaped groove plate is fixed on the fixing plate, and the cylinder body of the cylinder is fixed in the groove of the U-shaped groove plate. The U-shaped groove plate can effectively provide protection for the cylinder to prevent it from being damaged by external factors.

[0011] Preferably, the telescopic direction of the piston rod of the cylinder is parallel to the vertical direction. Through precise control, it is ensured that the cylinder can stably realize the vertical lifting action of the height adjustment ring, ensuring the accuracy and reliability of the operation.

[0012] Preferably, a connecting rod is further included, the lower end of the connecting rod is fixedly connected to the height adjustment ring, and the upper end of the connecting rod is fixedly connected to the connecting block. The height adjustment ring can be raised and lowered by controlling the connecting rod, and the height adjustment ring can be flexibly adjusted to meet the height requirements of different workspaces.

[0013] Preferably, the axis of the connecting rod is parallel to the vertical direction to ensure that the height adjustment ring is lifted vertically.

[0014] Preferably, one end of the connecting block is fixedly connected to the piston rod of the cylinder, and the other end of the connecting block is fixed with a pipe clamp, which can firmly fix the connecting rod to ensure a stable and reliable connection.

[0015] Preferably, the pipe clamp includes a clamp arm 1 and a clamp arm 2, and the ends of the clamp arm 1 and the clamp arm 2 away from the connection block are both provided with fastening screw holes, and fastening bolts are installed in the fastening screw holes. By tightening the bolts in the fastening screw holes, the pipe clamp can firmly clamp and fix the connecting rod to ensure the safety and stability of the connection.

[0016] It can be seen from the above technical solutions that the advantage of the utility model is that the lifting and lowering of the height-adjusting ring can be controlled by controlling the extension and retraction of the piston rod of the cylinder. After the capacitor height controller adjusts the height of the cutting gun through the capacitor on the height-adjusting ring, the height-adjusting ring is raised by controlling the cylinder, and then the flame cutting machine is controlled to perform cutting and perforation. At this time, the splashing cutting slag will not adhere to the height-adjusting ring and will not cause the height-adjusting ring to fail. When the perforation is completed, the height-adjusting ring is controlled to return to the original height, and the height-adjusting ring can continue to control the height of the cutting gun to the workpiece in real time to ensure smooth cutting. In summary, the device can increase the height of the height-adjusting ring when the flame cutting machine is cutting and perforating, ensuring that the splashing cutting slag will not cause the height-adjusting ring to fail, and can lower the height of the height-adjusting ring after the perforation is completed, so that the height-adjusting ring can continue to control the height of the cutting gun to the workpiece in real time.

DETAILED DESCRIPTION

[0024] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0025] A height adjustment device for a flame cutting machine, such as Figure 1 As shown, it includes a mounting frame 1, which can be fixed on the flame cutting machine by bolts, a cylinder 2 is fixed on the mounting frame 1, a connecting block 3 is fixed on the piston rod 21 of the cylinder 2, a height adjustment ring 5 is fixed on the connecting block 3, and a capacitor height controller is connected to the height adjustment ring 5. The capacitor height controller is an existing device, and the capacitor height controller can measure the height from the height adjustment ring 5 to the workpiece or the cutting gun through the capacitance on the height adjustment ring 5, thereby facilitating the adjustment of the height from the cutting gun to the workpiece.

[0026] like Figure 2 As shown, in this specific embodiment, the mounting frame 1 specifically adopts the following structure: the mounting frame 1 includes a fixing plate 11, the fixing plate 11 is arranged in a Z shape, and a fixing hole 111 is arranged on the surface of the fixing plate 11 away from the cylinder 2. There are two fixing holes 111, and the two fixing holes 111 are evenly distributed along the horizontal direction. In this embodiment, the fixing holes 111 are arranged in an oblong shape, and the length direction of the fixing holes 111 is parallel to the horizontal direction. In addition, bolts are installed in the two fixing holes 111, and the fixing plate 11 can be fixed to the flame cutting machine by the bolts.

[0027] like Figure 3 As shown, a U-shaped groove plate 12 is provided on the surface of the fixing plate 11 close to the cylinder 2, the bottom of the U-shaped groove plate 12 is connected to the fixing plate 11 by welding, and the notch of the U-shaped groove plate 12 is away from the fixing plate 11. In addition, a mounting hole is provided on the U-shaped groove plate 12, and a bolt is installed in the mounting hole. The cylinder body of the cylinder 2 is fixed in the groove of the U-shaped groove plate 12 through the bolt in the mounting hole, and the piston rod 21 of the cylinder 2 faces downward, and the telescopic direction of the piston rod 21 of the cylinder 2 is parallel to the vertical direction.

[0028] like Figure 4As shown, in this specific embodiment, the connection block 3 specifically adopts the following structure: the connection block 3 is placed horizontally, one end of the connection block 3 is fixedly connected to the piston rod 21 of the cylinder 2 by bolts, and the other end of the connection block 3 is welded with a pipe clamp 31. The pipe clamp 31 includes a clamp arm 1 312 and a clamp arm 2 313, and the middle positions of the clamp arm 1 312 and the clamp arm 2 313 are both provided with arc grooves, and the two arc grooves are positioned oppositely. The ends of the clamp arm 1 312 and the clamp arm 2 313 close to the connection block 3 are both connected to the connection block 3 by welding, and the ends of the clamp arm 1 312 and the clamp arm 2 313 away from the connection block 3 are both provided with fastening screw holes 311, and the two fastening screw holes 311 are positioned oppositely and have the same size. A fastening bolt is installed in the fastening screw hole 311, and when the fastening bolt enters the two fastening screw holes 311 at the same time, the clamp arm 1 312 and the clamp arm 2 313 can be controlled to clamp inward.

[0029] A connecting rod 4 is arranged between the two arc grooves of the clamp arm 1 312 and the clamp arm 2 313 . The upper end of the connecting rod 4 is clamped and fixed by the pipe clamp 31 . The lower end of the connecting rod 4 is fixedly connected to the height adjustment ring 5 by welding, and the axis of the connecting rod 4 is parallel to the vertical direction.

[0030] The specific use process of the utility model is as follows: first, the piston rod 21 of the cylinder 2 is controlled to extend so that the height adjustment ring 5 begins to descend. The capacitance change of the height adjustment ring 5 is monitored in real time by the capacitance height controller. Once the capacitance value reaches the preset threshold, the extension action of the piston rod 21 is immediately stopped to ensure that the height adjustment ring 5 is lowered to a suitable position. Next, the height of the flame cutting machine torch is adjusted. The capacitance of the height adjustment ring 5 is also monitored by the capacitance height controller to ensure that the height between the torch and the workpiece reaches a predetermined value before the adjustment is stopped. At this time, the height from the torch of the flame cutting machine to the workpiece reaches a predetermined height.

[0031] Subsequently, the piston rod 21 of the control cylinder 2 is retracted, driving the height adjustment ring 5 to rise, so as to prevent the splashing cutting slag from adhering to the height adjustment ring 5 when the flame cutting machine is started for perforation. After the perforation is completed, the piston rod 21 of the cylinder 2 is extended again to return the height adjustment ring 5 to the initial height. Finally, the flame cutting machine is started for cutting. The cutting slag generated during the cutting process of the flame cutting machine is very small and will not affect the height adjustment ring 5.

[0032] It can be seen from the above embodiments that the beneficial effect of the utility model is that the lifting and lowering of the height adjustment ring can be controlled by controlling the extension and retraction of the piston rod of the cylinder. After the capacitor height controller adjusts the height of the cutting gun through the capacitor on the height adjustment ring, the height adjustment ring is raised by controlling the cylinder, and then the flame cutting machine is controlled to perform cutting and perforation. At this time, the splashing cutting slag will not adhere to the height adjustment ring and will not cause the height adjustment ring to fail. When the perforation is completed, the height adjustment ring is controlled to return to the original height, and the height adjustment ring can continue to control the height of the cutting gun to the workpiece in real time to ensure smooth cutting. In summary, the device can increase the height of the height adjustment ring when the flame cutting machine is cutting and perforating, ensuring that the splashing cutting slag will not cause the height adjustment ring to fail, and can lower the height of the height adjustment ring after the perforation is completed, so that the height adjustment ring can continue to control the height of the cutting gun to the workpiece in real time.
