Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and more specifically, to a laser cutting device integrating a double crossbeam moving mechanism. Background Technology

[0002] Traditional laser cutting devices mostly use single-beam moving mechanisms, which have limited load-bearing capacity and are prone to vibration or deformation during high-speed movement, making it difficult to meet the high-precision cutting requirements of large-size plates (such as large-format metal plates) or thick materials. Currently, double-beam moving mechanisms have been gradually applied in the field of laser cutting, but they still face problems such as insufficient synchronous control accuracy of the beam, long-term stability decline due to guide rail wear, and difficulty in balancing mechanism size and processing flexibility. These issues are driving related technologies to continuously iterate towards servo drive optimization, lightweight material application, and intelligent error compensation.

[0003] Utility model patent CN215658486U discloses a dual-laser-head beam cutting mechanism, including a gantry frame, a laser cutting mechanism mounted on the gantry frame, and a pressure roller mechanism. The laser cutting mechanism includes a set of laser cutters and a drive module that drives the laser cutters to move perpendicular to the feeding direction. The pressure roller mechanism consists of two sets, installed at the same height between a set of positioning seats. Its structure includes an upper pressure roller and a lower pressure roller. The lower pressure roller is positioned and installed, while the upper pressure roller is movably installed, and buffer components are provided at both ends. This dual-laser-head beam cutting mechanism is applied to the cutting of sheet metal coils. By utilizing the positional movement of the dual laser cutters, the sheet metal coils are cut in the feeding direction, enabling the sheet metal coils to be cut into different widths. Combined with a traditional shearing machine, the sheet metal parts are cut into different lengths, achieving the purpose of rapid material feeding. The overall structure has strong adaptability.

[0004] Although the dual-laser-head beam cutting mechanism offers convenient material feeding, high speed, and strong overall structural adaptability, it still suffers from the following problems in practical use: the laser cutter's movement is relatively simple, and for cutting complex shapes or irregular graphics, multiple adjustments and repositioning may be required, resulting in poor flexibility and difficulty in achieving efficient and precise cutting. Therefore, we propose a laser cutting device integrating a dual-beam moving mechanism. Utility Model Content

[0005] Given the lack of flexibility in existing technologies, there is a need to provide a laser cutting device with an integrated double-beam moving mechanism.

[0006] In a first aspect, this application provides a laser cutting device with an integrated double-beam moving mechanism, including a base, a side plate fixedly connected to the top surface of the left end of the base, support plates fixedly connected to the top surfaces of both the front and rear ends of the base, a first crossbeam fixedly connected between the two support plates, a first adjusting component installed on the top surface of the first crossbeam, the first adjusting component including a first slider, the first slider and the first crossbeam being slidably connected, a second crossbeam fixedly connected to the bottom surface of the first slider, a second adjusting component installed on the bottom surface of the second crossbeam, the second adjusting component including a lead screw and a second slider threadedly connected to the lead screw, the lead screw being rotatably inserted into the second crossbeam, the second slider and the bottom surface of the second beam being slidably connected, a cylinder fixedly connected to the bottom surface of the second slider, the telescopic rod of the cylinder facing downwards and a laser cutter fixedly connected to the end of the rod.

The width of the gear groove is greater than the tooth tip circle diameter of the gear, and the size of the guide rail groove is adapted to the size of the guide rail. In this configuration, the gear groove protects the gears, reducing wear on the gears and rack caused by dust and debris; the precise fit between the guide rail groove and the guide rail reduces frictional loss between the slider and the guide rail, thereby extending the overall service life of the first adjustment component and reducing the maintenance cost of the device.

[0013] According to the technical solution provided in the embodiments of this application, a second motor is fixedly installed on the right side wall of the second crossbeam, and the output shaft of the second motor is coaxially connected with the lead screw.

[0016] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Please see Figures 1-4 A laser cutting device integrating a double crossbeam moving mechanism includes a base 1. A side plate 11 is fixedly connected to the top surface of the left end of the base 1. Support plates 12 are fixedly connected to the top surfaces of both the front and rear ends of the base 1. A first crossbeam 2 is fixedly connected between the two support plates 12. A first adjusting component 3 is installed on the top surface of the first crossbeam 2. The first adjusting component 3 includes a first slider 33, which is slidably connected to the first crossbeam 2. A second crossbeam 4 is fixedly connected to the bottom surface of the first slider 33. A second adjusting component 5 is installed on the bottom surface of the second crossbeam 4. The second adjusting component 5 includes a lead screw 51 and a second slider 52 threadedly connected to the lead screw 51. The lead screw 51 is rotatably inserted into the second crossbeam 4. The second slider 52 is slidably connected to the bottom surface of the second crossbeam 4. A cylinder 53 is fixedly connected to the bottom surface of the second slider 52. The telescopic rod of the cylinder 53 faces downward and a laser cutter 6 is fixedly connected to the end of the rod.

[0018] In this embodiment, as Figure 2 As shown, the first adjustment component 3 also includes a rack 31 and a guide rail 32. Both the rack 31 and the guide rail 32 are fixedly connected to the top surface of the first crossbeam 2. The guide rail 32 provides precise guidance for the sliding of the first slider 33 along the first crossbeam 2, avoiding deviation or jamming during the sliding process of the first slider 33, ensuring the straightness of the movement, which directly affects the path accuracy of laser cutting. The first slider 33 has a through groove 331 for accommodating the passage of the first crossbeam 2, which increases the contact area between the first slider 33 and the first crossbeam 2, improves the stability during the sliding process, and reduces cutting errors caused by vibration.

[0019] Furthermore, such as Figure 2 and Figure 3As shown, a gear 34 is rotatably engaged with the top surface of the slot 331. The gear 34 meshes with the rack 31. When the gear 34 rotates, it converts the rotational motion of the gear 34 into the linear motion of the first slider 33 along the first crossbeam 2 through the meshing action with the fixed rack 31, thereby driving the second crossbeam 4 and the laser cutter 6 to move back and forth.

[0020] Furthermore, such as Figure 3 As shown, a first motor 35 is fixedly installed on the top surface of the first slider 33. The output shaft of the first motor 35 passes through the top surface of the first slider 33 and is coaxially connected to the gear 34. The first motor 35 serves as a driving component. After being powered on, the output shaft drives the gear 34 to rotate. The gear 34 drives the first slider 33 to slide along the first crossbeam 2 through meshing with the rack 31, thus realizing the forward and backward movement of the laser cutter.

[0021] It is important to note that, such as Figure 3 As shown, the first slider 33 also has a gear groove 332 and a guide rail groove 333 that communicate with the through groove 331. The width of the gear groove 332 is greater than the tip circle diameter of the gear 34. The gear groove 332 provides an independent installation space for the gear 34. The width of the groove is greater than the tip circle diameter of the gear to avoid friction and collision between the gear 34 and the inner wall of the first slider 33 when the gear rotates. At the same time, it prevents dust and debris generated during the cutting process from entering the meshing area between the gear 34 and the rack 31, ensuring smooth transmission. The size of the guide rail groove 333 is matched with the size of the guide rail 32, so that the guide rail 32 can slide in the guide rail groove 333. This increases the mating depth between the first slider 33 and the guide rail 32, prevents the first slider 33 from disengaging from the guide rail 32 during sliding, and further improves the guiding accuracy and stability of the forward and backward movement.

[0022] In this embodiment, as Figure 1 As shown, a side sliding groove 111 is provided on the right side wall of the side plate 11. The width of the side sliding groove 111 is adapted to the height of the second crossbeam 4, so that when the second crossbeam 4 moves, the left end always slides along the side sliding groove 111, avoiding the second crossbeam 4 from shifting left and right, ensuring that the second crossbeam 4 remains perpendicular to the first crossbeam 2, and thus ensuring that the movement path of the laser cutter 6 is parallel to the first crossbeam 2.

[0023] Furthermore, such as Figure 1As shown, a limiting rod 112 is fixedly connected inside the side sliding groove 111. The limiting rod 112 passes through the second crossbeam 4 and is slidably connected to it. The limiting rod 112 passes through the second crossbeam and can limit the displacement of the second crossbeam 4 in the left and right directions, so as to avoid the second crossbeam 4 from shifting to the left or right due to vibration or external force during the movement process. This further enhances the lateral guiding effect of the side sliding groove 111, ensuring that the second crossbeam 4 always moves in the front and back direction. The limiting rod 112 also forms an anti-detachment protection for the second crossbeam 4, avoiding the risk of the second crossbeam 4 detaching from the side sliding groove 111 due to the gap between the side sliding groove 111 and the second crossbeam 4 during the movement process, and ensuring that the cooperation between the second crossbeam 4 and the side sliding groove 111 is always stable.

[0024] It is worth mentioning that, such as Figure 4 As shown, a second motor 54 is fixedly installed on the right side wall of the second crossbeam 4. The output shaft of the second motor 54 is coaxially connected to the lead screw 51. After the second motor 54 is powered on, the output shaft drives the lead screw 51 to rotate. The rotational motion of the lead screw 51 is converted into the linear motion of the second slider 52 along the bottom surface of the second crossbeam 4, which in turn drives the cylinder 53 and the laser cutter 6 to move in the left and right directions.

[0025] Finally, it should be noted that the first motor 35, the second motor 54, the cylinder 53, and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0026] Working Principle: In this embodiment, the laser cutting device with integrated double crossbeam moving mechanism first drives the gear 34 to rotate via the first motor 35. Since the gear 34 meshes with the rack 31 on the top surface of the first crossbeam 2, and the first slider 33 slides along the guide rail 32 on the first crossbeam 2 via the guide rail groove 333, the first slider 33 slides along the first crossbeam 2, thereby driving the second crossbeam 4, which is fixedly connected to it, to move synchronously. The left end of the second crossbeam 4 slides in the side sliding groove 111 of the side plate 11, and the limiting rod 112 plays a limiting and guiding role in its movement. After the second crossbeam 4 moves to the target position, the second motor 54 starts and drives the lead screw 51 in the second crossbeam 4 to rotate. The second slider 52, which is threadedly connected to the lead screw 51, slides along the bottom surface of the second crossbeam 4, thereby driving the cylinder 53 fixed at its bottom and the laser cutter 6 at the end of the cylinder 53 extension rod to move to the target corresponding position. Finally, the extension rod of the cylinder 53 extends downward, driving the laser cutter 6 to approach the workpiece to be cut and complete the cutting operation.

[0027] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
