[0002] Laser cutting is a processing method that uses a high-power-density laser beam as a heat source. Through computer-aided design and computer-aided manufacturing technologies, according to the designed cutting trajectory, the workpiece to be processed reaches surface melting, evaporation or decomposition under the irradiation of the laser beam, thereby forming a cut. The laser plate cutting machine can focus the laser beam emitted by the laser into a light spot with a high power density, irradiate it on the surface of the plate, quickly heat the material to the melting point or boiling point, and blow away the molten or vaporized material through the high-pressure gas coaxial with the beam, thereby achieving the purpose of cutting.

[0003] In the cutting process of the existing laser plate cutting machine, the metal plate is directly placed on the plate cutting machine, and the flying objects generated during the cutting process of the metal plate pose a threat to the operator. Therefore, it is necessary to provide a laser plate cutting machine with an anti-deviation function to solve the above technical problems. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a laser plate cutting machine with an anti-deviation function.

Detailed Implementation Manner

[0019] The present utility model will be further described below in conjunction with the accompanying drawings and the implementation manner.

[0020] Please refer to Figures 1 to 4 , a laser cutting machine for plates with an anti-deviation function, including a tabletop 1. On both sides of the top of the tabletop 1, sliding channels 2 are symmetrically arranged. A chute 18 is provided in the sliding channel 2. A base 3 and a first sliding seat 4 are arranged on the chute 18. The base 3 can move horizontally inside the chute 18 above the first sliding seat 4. A threaded hole is provided in one of the first sliding seats 4, and a first threaded rod 5 is connected in the threaded hole. One end of the first threaded rod 5 far from the threaded hole is provided with a first motor 13. The transmission shaft of the first motor 13 is in transmission connection with the first threaded rod 5, and the first motor 13 is fixed on one side of the sliding channel 2;

[0021] Two symmetrically distributed limiting grooves 16 are provided on the tabletop 1. Limiting blocks 10 are arranged in the limiting grooves 16. A clamping plate 9 is connected to the top of the limiting block 10. Baffles 17 are connected to both ends of the clamping plate 9. A threaded groove is provided through the limiting block 10, and a double-headed threaded rod 15 is installed in the threaded groove. One end of the double-headed threaded rod 15 close to the first threaded rod 5 is connected with a second motor 14. The transmission shaft of the second motor 14 is in transmission connection with the double-headed threaded rod 15. A driving box is installed below the tabletop 1. The driving box is a box structure with a detachable bottom through screws. The motor 2 is installed on the inner side wall of the driving box, and an opening communicating with the limiting groove 16 is also provided in the driving box. The limiting block 10 extends into the driving box, and the end of the double-headed threaded rod 15 far from the second motor 14 is connected to the inner box wall of the driving box far from the second motor 14 through a bearing.

[0022] In the specific implementation process, adjust the position and width of the clamping mechanism according to the size of the plate to be cut. By starting the first motor 13 to drive the first threaded rod 5 to rotate, the base 3 and the first sliding seat 4 are moved to a suitable position in the chute 18. Then start the second motor 14 to drive the double-headed threaded rod 15 to rotate, and adjust the positions of the limiting block 10 and the clamping plate 9 to clamp the plate. Once the plate is firmly clamped, the laser cutter head can be started for cutting operations.

[0023] It should be noted that: The tabletop 1 serves as the working platform of the entire laser cutting machine for supporting and fixing the plate to be cut. The sliding channels 2 are symmetrically arranged on both sides of the top of the tabletop 1, and the internally opened sliding grooves 18 are used to guide the horizontal movement of the base 3 and the first sliding seat 4, enabling the cutting mechanism to flexibly adjust its position in the horizontal direction to adapt to plates of different sizes.

[0024] It should be noted that: When the first threaded rod 5 rotates, the first sliding seat 4 connected thereto and the base 3 thereon will move along the sliding groove 18, thereby adjusting the position of the cutting mechanism. The top of the limit block 10 is connected to the clamping plate 9, and the clamping plate 9 is used to directly clamp the plate, ensuring the stability of the two clamping plates 9 in the vertical direction and allowing the clamping height of the clamping plate to be changed by adjusting the position of the limit block 10.

[0025] It should be noted that: When the second motor 14 drives the double-headed threaded rod 15 to rotate, the two limit blocks 10 will move towards the center or towards both sides simultaneously, thereby adjusting the clamping width of the clamping plate to adapt to plates of different widths.

[0026] Reference Figure 1 and Figure 2 As shown in the figure, a laser cutting machine with an anti-deviation function is provided. An installation box 21 is provided on one of the bases 3. An installation block 19 is provided on one side of the installation box 21 close to the tabletop 1. The installation blocks 19 are symmetrically distributed relative to the tabletop 1. The other installation block 19 is fixedly connected to one of the bases 3 far from the first threaded rod 5. A second threaded rod 7 is rotatably connected between the two installation blocks 19. A third motor 12 is provided inside the installation box 21. The transmission shaft of the third motor 12 is in transmission connection with one end of the second threaded rod 7. A second sliding seat 8 is connected to the second threaded rod 7. The second sliding seat 8 is threadedly connected to the second threaded rod 7. The laser cutter head 11 is installed at the bottom of the second sliding seat 8.

[0027] In the specific implementation process, first, according to the size and cutting requirements of the plate to be cut, the plate is clamped by adjusting the position and width of the clamping mechanism. Then, the third motor 12 is started to drive the second threaded rod 7 to rotate, so that the second sliding seat 8 moves along the second threaded rod 7 to a suitable cutting starting position. Next, according to the cutting path and speed requirements, the laser cutter head 11 is controlled to emit a laser beam for cutting operations. During the entire cutting process, the position and moving speed of the laser cutter head 11 are precisely controlled by the control system to ensure the cutting quality and efficiency. The control system can be set above and on the side of the tabletop 1.

[0028] It should be noted that: The installation box 21 is arranged on a base 3 and fixed by bolts, and is used to install and fix the motor three 12, the central control device and the storage battery. The switch and the output end of the central control device are connected to the input ends of the motor one 13, the motor two 14, the motor three 12 and the laser cutter head 11 through wires. The central control device is electrically connected to the storage battery. A sleeve is provided on the fixing rod 20, and the power cord of the laser cutter head 11 is connected to the installation box 21 through the inside of the sleeve. A part of the power cord is reserved inside the sleeve. When the laser cutter head 11 moves to the maximum range away from the installation box 21, the reserved power cord in the sleeve ensures that it can move within the maximum range. The wire of the motor one 13 passes through the side of the sliding channel 2 and is connected to the central control device. The power cord of the motor two 14 passes through the hole reserved under the table top 1 and is connected to the central control device. The installation block 19 is connected to the threaded rod two 7 in a rotational connection manner, providing a stable support and a rotational basis for the threaded rod two 7.

[0029] It should be noted that: One end of the threaded rod two 7 is connected to the transmission shaft of the motor three 12 and is driven by the motor three 12 to rotate. When the threaded rod two 7 rotates, the slide block two 8 threadedly connected to it will move along the threaded rod two 7, thereby driving the laser cutter head 11 to make precise adjustments in the horizontal direction.

[0030] Reference Figure 3 As shown, a laser plate cutting machine with an anti-deviation function includes fixing rods 20 provided on both the upper and lower sides of the threaded rod two 7 on the installation block 19.

[0031] In the specific implementation process, ensure that the installation block 19 is firmly fixed on the base 3. Then, pass the threaded rod two 7 through the through hole of the installation block 19, and install the fixing rods 20 on its upper and lower sides. The fixing rods 20 can be connected to the installation block 19 and the threaded rod two 7 through bolts to ensure its stability and reliability.

[0032] It should be noted that: The setting of the fixing rod 20 increases the support points of the threaded rod two 7, making the threaded rod two 7 more stable when rotating and bearing the weight of the slide block two 8 and the laser cutter head 11 thereon. This helps to reduce errors caused by vibration or imbalance and improve the cutting accuracy.

[0033] Reference Figure 4 As shown, a laser plate cutting machine with an anti-deviation function includes that two adjacent baffles 17 on the clamping plate 9 are distributed in a staggered manner, and the outer side surface of one baffle 17 can be attached to the inner side surface of another adjacent baffle 17.

[0034] In the specific implementation process, the baffles can be effectively docked by the clamping and moving closer and farther away of the two clamping plates 9.

[0035] It should be noted that: The staggered baffle design has a certain flexibility and can adapt to plates of different sizes and shapes.

[0036] Reference Figure 1 As shown, a laser cutting machine for plates with an anti-deviation function includes a top plate 6 provided on a base 3. The top plate 6, the table top 1, and the clamping plate 9 are made of alloy steel sheet metal parts.

[0037] It should be noted that: Alloy steel is a kind of steel made by adding an appropriate amount of one or more alloying elements on the basis of ordinary steel. It has higher strength and rigidity and can withstand greater loads and impact forces. In a laser cutting machine for plates, the top plate 6, the table top 1, and the clamping plate 9, as key load-bearing components, need to have good rigidity and stability to ensure the smooth progress of the cutting operation.

[0038] Reference Figure 4 As shown, a laser cutting machine for plates with an anti-deviation function includes that the outer side of the baffle 17 away from the table top 1 is made of transparent tempered glass.

[0039] It should be noted that: The transparent tempered glass material allows the operator to clearly observe the state of the plate during the laser cutting process, including the cutting path, cutting depth, and whether the plate deviates, etc.

[0040] The working principle of a laser cutting machine for plates with an anti-deviation function provided by the present utility model is as follows:

[0041] Sliding channels 2 are provided on both sides of the top of the table top 1, and chutes 18 are opened inside. The base 3 horizontally moves in the chute 18 through the first sliding seat 4, realizing the flexible adjustment of the cutting mechanism in the horizontal direction. By driving the first threaded rod 5 to rotate through the first motor 13, the first sliding seat 4 and the base 3 are driven to move in the chute 18 to the required position, realizing the precise positioning of the cutting mechanism;

[0042] Limit blocks 10 in symmetrically distributed limit slots 16 on the table top 1 are connected to the second motor 14 through a double-headed threaded rod 15. When the second motor 14 works, the double-headed threaded rod 15 rotates, driving the two limit blocks 10 to move towards the center or towards both sides simultaneously, thereby adjusting the clamping width of the clamping plate 9 to adapt to plates of different widths;

[0043] An installation box 21 is provided on a base 3, and a third motor 12 and a second threaded rod 7 are installed inside. The third motor 12 drives the second threaded rod 7 to rotate, driving the second sliding seat 8 to move along the second threaded rod 7, thereby adjusting the cutting starting position of the laser cutter head 11. The laser cutter head 11 emits a laser beam for cutting operations according to the preset cutting path and speed requirements.

[0044] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
