Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and in particular to an auxiliary device of a laser cutting head. Background Art

[0002] The laser cutting head is an important component of the laser cutting machine. It is mainly used to focus the high-energy laser beam on the surface of the material, thereby achieving precise cutting of various materials.

[0003] A laser cutting head usually consists of the following main components: Laser source: a device that generates a laser beam. Common laser sources include CO2 lasers and fiber lasers. Focusing lens: a lens that focuses the laser beam onto the surface of the cutting material, usually made of high-quality optical glass. Jet system: During the cutting process, gas (such as oxygen, nitrogen or air) is usually injected to help remove the slag produced by the cutting and provide a good cutting effect. Positioning system: used to adjust the position of the laser head to ensure the accuracy of the cutting path. Cooling system: prevents the laser cutting head from overheating and ensures the stable operation of the equipment.

[0004] Laser cutting heads are an indispensable tool in modern manufacturing technology. Their efficient and precise cutting capabilities have led to their widespread use across multiple industries. As technology continues to advance, laser cutting heads will continue to evolve, pushing the manufacturing industry to new heights.

[0005] When processing new energy vehicle parts, when underwater cutting is required for aluminum alloy battery shell processing, the water film can reduce the reflectivity to below 20% and quickly remove the cutting heat. When existing laser cutting heads are used for cutting underwater, there is no water-free space. The water and turbidity in the water will refract and scatter the propagation of the laser, resulting in laser energy loss and thus reduced cutting efficiency.

[0006] In summary, the prior art lacks a technology for waterless assisted cutting with a laser cutting head. Summary of the Invention

[0031] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0032] As Figures 1-9 shown, an auxiliary device for a laser cutting head includes a semi-circular cover A1. A semi-circular cover B2 is movably inserted on one side of the semi-circular cover A1. Sealing covers 3 are installed at both ends of the semi-circular cover A1 and the semi-circular cover B2. Two mounting mechanisms 4 are symmetrically and slidably arranged in the semi-circular cover A1 and the semi-circular cover B2. A connection mechanism 5 is rotatably connected to the semi-circular cover B2. A protective cover 6 is slidably arranged in the semi-circular cover A1. A laser cutting head 7 is arranged in the protective cover 6. A drainage and air guide seat 8 is fixedly connected to one side of the semi-circular cover A1. A sealing gasket is connected to the side surface of one end of the semi-circular cover A1, the semi-circular cover B2 and the sealing cover 3.

[0033] As Figure 3 shown, a plurality of jacks 301 are opened on the sealing cover 3, and a sealing strip 302 is fixedly connected to the bottom of the sealing cover 3.

[0034] As Figure 4 、 Figure 5As shown, the installation mechanism 4 includes an arc-shaped frame 401. The arc-shaped frame 401 is slidably fitted with the inner wall of the semi-circular cover A1. A threaded rod 402 is penetratingly and threadedly connected to the arc-shaped frame 401. The threaded rod 402 is rotatably connected to the inner wall of the semi-circular cover A1. One end of the threaded rod 402 is fixedly connected with a universal joint 403. The other end of the universal joint 403 extends to the outside and is fixedly connected with a knob 404. Rotating the universal joint 403 connected to the knob 404 causes the universal joint 403 to drive the connected threaded rod 402 to rotate, causing the threaded rod 402 to drive the arc-shaped frame 401 to move downward.

[0035] A plurality of insertion rods 405 are fixedly connected to the arc-shaped frame 401. The insertion rods 405 are slidably fitted with the inner wall of the semi-circular cover A1. The insertion rods 405 are inserted into the insertion holes 301. A limiting rod 406 is slidably fitted inside the insertion rod 405. The top end of the limiting rod 406 is in movable contact with the outer wall of the sealing cover 3. One end of the limiting rod 406 is fixedly connected with a spring 407. The other end of the spring 407 is fixedly connected with the inner wall of the insertion rod 405. The bottom end of the limiting rod 406 is fixedly connected with a conical head 408. The conical head 408 is in sliding contact with the inner wall of the semi-circular cover A1. When the conical head 408 is not in contact with the inner wall of the semi-circular cover A1, under the action of the spring 407, the limiting rod 406 will be driven out. Then when the insertion rod 405 moves downward, the sealing cover 3 will be driven by the limiting rod 406 to press on both ends of the semi-circular cover A1 and the semi-circular cover B2 for connection.

[0036] As Figure 6 shown, connection grooves 101 are formed on both sides of the semi-circular cover A1. Limiting grooves 102 are formed inside both the semi-circular cover A1 and the semi-circular cover B2. Arc-shaped racks 103 are fixedly connected inside both the semi-circular cover A1 and the semi-circular cover B2. Connecting rods 104 are fixedly connected to both ends of the semi-circular cover A1. The connecting rods 104 are slidably fitted with the semi-circular cover B2. Align the connecting rods 104 on the semi-circular cover A1 with the semi-circular cover B2 and put the semi-circular cover A1 and the semi-circular cover B2 together.

[0037] As Figure 7 shown, the connection mechanism 5 includes a universal joint group 501. The universal joint group 501 is rotatably connected to the semi-circular cover B2. Worm gears 502 are fixedly connected to both ends of the universal joint group 501. A worm wheel 503 is meshed and driven on one side of each worm gear 502. The worm wheel 503 is rotatably connected to the semi-circular cover B2. A connecting rod 504 is fixedly connected to the worm wheel 503. The other end of the connecting rod 504 is slidably fitted with the inner wall of the connection groove 101. Rotating the universal joint group 501 causes the universal joint group 501 to drive the two worm gears 502 to rotate, causing the worm gears 502 to drive the connecting rods 504 connected to the worm wheels 503 to rotate, causing the other ends of the connecting rods 504 to rotate into the connection grooves 101, realizing the connection of the semi-circular cover A1 and the semi-circular cover B2 and fixing the semi-circular cover A1 and the semi-circular cover B2 on the pipeline.

[0038] As Figure 8 shown, one end of the protective cover 6 is fixedly connected with a slider 601. The slider 601 is slidably matched with the inner wall of the limiting groove 102. The inner wall of the bottom end of the protective cover 6 is fixedly connected with a motor A 602. The output end of the motor A 602 is fixedly connected with a gear 603. The gear 603 is meshed and driven with the arc-shaped rack 103. The connected gear 603 is driven by the motor A 602 to rotate, so that the gear 603 meshes with the arc-shaped rack 103, thereby driving the slider 601 to slide in the limiting groove 102, and making the protective cover 6 rotate around the pipeline.

[0039] As Figure 8 shown, a rotating plate 701 is fixedly connected to the laser cutting head 7. One end of the rotating plate 701 is rotatably connected to the protective cover 6. One end of the rotating plate 701 is fixedly connected with a motor B 702. The motor B 702 is fixedly connected with the protective cover 6. A plurality of cameras 703 are fixedly installed on the rotating plate 701. The connected rotating plate 701 is driven by the motor B 702 to rotate, so that the laser cutting head 7 moves out. At this time, the internal situation is observed through the cameras 703.

[0040] As Figure 9 shown, a water pump 801 is fixedly installed in the drainage and air guide seat 8. The input end of the water pump 801 extends into the semi-circular cover A1 and is fixedly connected with a drain pipe 802. The output end of the water pump 801 extends outside the drainage and air guide seat 8. Two air pumps 803 are fixedly installed in the drainage and air guide seat 8. The input ends of the air pumps 803 are communicated with the inside of the semi-circular cover A1. The output ends of the air pumps 803 extend outside the drainage and air guide seat 8. During cutting, a protective gas is injected into the semi-circular cover A1 and the semi-circular cover B2 through one air pump 803, and the fume gas generated by cutting is discharged through the other air pump 803.

[0041] Working principle: When cutting an underwater pipeline, first select a suitable sealing cover 3 according to the size and shape of the pipeline. Align the sealing cover 3 with both ends of the semi-circular cover A1 and the semi-circular cover B2, so that the insertion holes 301 on the sealing cover 3 are inserted on the insertion rods 405. Then rotate the universal joint 403 connected to the knob 404, so that the universal joint 403 drives the connected threaded rod 402 to rotate, so that the threaded rod 402 drives the arc-shaped frame 401 to move downward. At this time, when the tapered head 408 does not contact the inner wall of the semi-circular cover A1, under the action of the spring 407, the limiting rod 406 is driven to move out. Then when the insertion rod 405 moves downward, the sealing cover 3 is driven by the limiting rod 406 to press on both ends of the semi-circular cover A1 and the semi-circular cover B2 for connection;

[0042] Then align the splicing rod 104 on the semi-circular cover A1 with the semi-circular cover B2, put the semi-circular cover A1 and the semi-circular cover B2 together, and then rotate the universal joint group 501 so that the universal joint group 501 drives the two worm gears 502 to rotate, and the worm gears 502 drive the connecting rod 504 connected to the worm wheel 503 to rotate, so that the other end of the connecting rod 504 rotates into the connecting groove 101, realizing the connection of the semi-circular cover A1 and the semi-circular cover B2, and fixing the semi-circular cover A1 and the semi-circular cover B2 on the pipeline;

[0043] Then use the water pump 801 to drain the water in the semi-circular cover A1 and the semi-circular cover B2 through the drain pipe 802, and then use the motor B702 to drive the connected rotating plate 701 to rotate, so that the laser cutting head 7 moves out. At this time, observe the internal situation through the camera 703. Through remote control, use the motor A602 to drive the connected gear 603 to rotate, so that the gear 603 meshes with the arc-shaped rack 103, thereby driving the slider 601 to slide in the limiting groove 102, making the protective cover 6 rotate around the pipeline, and then the laser cutting head 7 cuts the pipeline. During cutting, inject protective gas into the semi-circular cover A1 and the semi-circular cover B2 through an air pump 803, and discharge the fume gas generated by cutting through another air pump 803.
