Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, in particular to a hull component processing numerical control laser cutting device. Background Art

[0002] In the shipbuilding industry, the machining accuracy of hull components directly impacts the overall performance and safety of a vessel. CNC laser cutting equipment, with its high precision and efficiency, has become a core component of hull component processing. CNC laser cutting uses a high-energy-density laser beam to instantly melt or vaporize the material being cut, enabling precise machining of complex hull components.

[0003] In actual production, existing CNC laser cutting equipment has significant drawbacks. For example, the patent application CN119897618A, titled "Upper Slide Suspended Hull Metal Laser Cutting Equipment," solves the problem of transporting hull metal steel plates. However, the metal debris, slag, and other waste generated during laser deck cutting are easily scattered and scatter. The equipment lacks an efficient collection device. While some equipment features simple debris collection mechanisms, these only collect a small amount of debris located in a fixed area, making it difficult to address debris dispersion caused by airflow disturbances and changes in cutting direction during the cutting process. Furthermore, the debris collection components of most equipment are difficult to clean, requiring shutdown and disassembly, which not only reduces production efficiency but also increases maintenance costs. Furthermore, uncollected debris accumulates on the workbench, affecting the accuracy of subsequent cutting operations and potentially causing secondary splashing due to laser beam irradiation, posing a threat to operator safety and hindering the cleanliness of the production workshop. Therefore, a CNC laser cutting system for processing hull components is provided that effectively collects debris, improves collection efficiency, facilitates cleaning and maintenance, and ensures cutting accuracy and production safety.

The cutting gun 15 is a prior art and will not be described in detail; the barrel cover 16 is sleeved on the cutting gun 15, and the barrel cover 16 is provided. When the cutting gun 15 is working, it can prevent the debris from splashing to the outside, so that the debris is collected in the barrel cover 16 and falls onto the deck 3 under the action of gravity. The barrel cover 16 can also collect the smoke generated during cutting to reduce air pollution. Through the collection device, the debris remaining on the deck 3 can be collected after cutting. The three-claw frame 30 serves as a mounting support for the drive disk 34 and the sweeper 46. When the L-shaped seat 14 moves, it can drive the collection device, bucket 29, collection box 27 to move synchronously, and the bucket 29 can contact the upper end surface of the deck 3, that is, move along the upper end surface of the deck 3.

[0035] The upper ends of the machine tool 1 are both slidably connected to first support seats 5, and the first support seats 5 are each provided with a first motor 6. The output end of the first motor 6 is fixedly connected to a first spur gear 7. The machine tool 1 is also provided with a first spur rack 8 meshing with the first spur gear 7. The cutting frame 4 is fixedly connected to the two first support seats 5.

[0036] like Figure 1-Figure 3 As shown, the first support seat 5 is connected to the upper end of the machine tool 1 by sliding the guide rail and the slider back and forth, that is, the first support seat 5 can move back and forth on the upper end surface of the machine tool 1, that is, the limited cutting frame 4 can only move back and forth; the first motor 6 is fixed to the first support seat 5 by bolts. The function of the first motor 6 is to provide rotational force for the first spur gear 7. The motor is existing technology and will not be described in detail; through the engagement of the first spur gear 7 and the first spur rack 8, when the first motor 6 is started, it can drive the first support seat 5 and the cutting frame 4 to move forward or backward, that is, drive the cutting gun 15 to move forward and backward; the first motor 6 can be set as one or two. When one is set, it can also drive the first support seat 5, the cutting frame 4, etc. to move forward and backward, but the stability is poor and the cost is relatively low. It is selected according to needs.

[0037] The cutting frame 4 is slidably connected to a second support seat 10, and a second motor 13 is provided on the second support seat 10. The output end of the second motor 13 is fixedly connected to a second spur gear 11, and a second spur rack 12 meshing with the second spur gear 11 is fixedly connected to the cutting frame 4. The L-shaped seat 14 is installed on the second support seat 10.

[0038] like Figure 2 and 4 - Figure 5 As shown, the second support seat 10 is connected to the cutting frame 4 by sliding left and right through guide rails and sliders, that is, the second support seat 10 is limited to move left and right on the cutting frame 4; the second motor 13 is fixed to the second support seat 10 by bolts, and the function of the second motor 13 is to provide rotational force for the second spur gear 11; when the second motor 13 is started, it can drive the second spur gear 11 to rotate, and when the second spur gear 11 rotates, it will drive the second support seat 10, L-shaped seat 14, cutting gun 15, etc. to move left or right through engagement with the second spur rack 12.

[0039] The L-shaped seat 14 is slidably connected to the second support seat 10 . The second support seat 10 is further provided with a telescopic cylinder 9 . The L-shaped seat 14 is arranged at the telescopic end of the telescopic cylinder 9 .

[0040] like Figure 4 As shown, the L-shaped seat 14 can be slidably connected to the front end of the second support seat 10 up and down, and the telescopic cylinder 9 can drive the L-shaped seat 14 to move up and down, that is, drive the collecting device, cutting gun 15, etc. to move up and down. The telescopic cylinder 9 can be a pneumatic cylinder, a liquid cylinder, or an electric cylinder. The telescopic cylinder 9 is an existing technology and will not be repeated.

[0041] The cutting gun 15 is fixedly connected to the L-shaped seat 14, and the barrel cover 16 is sleeved on the outer surface of the cutting gun 15. The L-shaped seat 14 is fixedly connected to the reinforcement seat 56, and the barrel cover 16 is fixedly connected to the reinforcement seat 56. The lower end of the barrel cover 16 is fixedly connected to a round base 17, and the inner wall of the lower end of the round base 17 is provided with a plurality of rolling balls 18. The upper end of the L-shaped seat 14 is also provided with an air pump 19 and a collection tank 20. The air inlet of the air pump 19 is connected to the barrel cover 16 pipe, and the air outlet of the air pump 19 is connected to the collection tank 20 pipe.

[0042] like Figure 4 and Figure 6-Figure 7 As shown, the cutting gun 15 is fixedly connected to the L-shaped seat 14 through the support seat, that is, when the L-shaped seat 14 moves up and down or moves left and right, it can drive the cutting gun 15 to move up and down or left and right; the barrel cover 16 is sleeved on the outer surface of the cutting gun 15, and the barrel cover 16 is fixedly connected to the reinforcement seat 56. When the L-shaped seat 14 and the cutting gun 15 move up and down or move left and right, the corresponding barrel cover 16 can move up and down or left and right synchronously with the L-shaped seat 14; the installation and shape of the barrel cover 16, the round base 17, and the ball 18 are as shown Figure 7 As shown, the ball 18 can roll on the inner wall of the round base 17. When in use, the telescopic cylinder 9 is controlled to work so that the L-shaped seat 14, the barrel cover 16, the cutting gun 15, etc. move downward synchronously. When the barrel cover 16, the round base 17, the ball 18, etc. move downward to the specified position, that is, when the ball 18 contacts the upper end surface of the deck 3, the telescopic cylinder 9 is controlled to stop moving and the cutting gun 15 is started. Then, the deck 3 can be cut by moving left and right and forward and backward. During cutting, the debris and smoke can be collected to prevent the debris from splashing and reduce the leakage of smoke. When the barrel cover 16 moves, the contact between the ball 18 and the deck 3 can reduce the friction between the deck 3. At this time, the debris will fall to the upper end surface of the deck 3 under the action of gravity. Since the ball 18 is round, the base does not directly contact the deck 3, that is, there is a certain gap at the lower end of the barrel seat to allow the debris to flow out. When the barrel cover 16 continues to follow the cutting gun 15 to cut and move, the debris will gather and remain in the path position passed by the barrel cover 16, which can be more conveniently collected when the collection device is working. The air pump 19 and the collection tank 20 are installed and shaped as shown in the figure. Figure 6 or Figure 7 As shown, the air pump 19 can extract the flue gas in the cylinder cover 16 and transport it to the collection tank 20 when working. The collection tank 20 is filled with activated carbon, solution, etc., which can purify the flue gas and then discharge it to the outside. The air pump 19 and the collection tank 20 are both existing technologies and will not be repeated here.

[0043] The inner wall of the L-shaped seat 14 is rotatably connected to a transmission cylinder 24, a support frame 25 is fixedly connected to the lower end of the transmission cylinder 24, a worm gear 23 is fixedly connected to the upper end of the outer surface of the transmission cylinder 24, and a third motor 21 is also provided on the L-shaped seat 14, and the output end of the third motor 21 is fixedly connected to a worm 22 that meshes with the worm gear 23; a flattening roller 26 is provided on one side of the lower end of the support frame 25.

[0044] like Figure 7 As shown, the support frame 25 is rotatably connected to the inner wall of the L-shaped seat 14 through the transmission cylinder 24, that is, the support frame 25 can rotate and move at the lower end of the L-shaped seat 14; the third motor 21 is fixed to the L-shaped seat 14, and the function of the third motor 21 is to provide a rotating force for the worm 22. The outer surface of the worm 22 is also rotatably connected to the bearing seat. The limited worm 22 can only rotate on the L-shaped seat 14. When the worm 22 rotates, it can drive the transmission cylinder 24 to rotate and the support frame 25 to rotate and move, that is, according to the cutting gun 15 The direction of movement of the support frame 25 and the collecting device is adjusted. Even if the collecting device is always at the rear end of the cutting gun 15, it is convenient to collect the debris after cutting. The flattening roller 26 is always at the front end of the cutting gun 15, and can squeeze the deck 3 before cutting to prevent the unevenness of the deck 3 from causing cutting errors. In addition, under the engagement of the worm wheel 23 and the worm 22, it has a self-locking function, that is, when the worm 22 does not rotate, the corresponding support frame 25 and the flattening roller 26 will not rotate or move; one side of the lower end surface of the support frame 25 is fixed to There is a U-shaped seat, and the flattening roller 26 is rotatably connected to the U-shaped seat. When the L-shaped seat 14 moves up and down, it can drive the support frame 25, the flattening roller 26, etc. to move up and down synchronously. When the L-shaped seat 14 moves downward to the specified position, that is, after the ball 18 contacts the upper end surface of the deck 3, the flattening roller 26 can contact the upper end surface of the deck 3. When the L-shaped seat 14 and the cutting gun 15 move to cut, the flattening roller 26 can be driven to move synchronously, that is, the flattening roller 26 can flatten the deck 3 before cutting, thereby improving the cutting accuracy. The flattening roller 26 A rubber surface is also provided on the outer surface. When the flattening roller 26 contacts the deck 3 and rotates and moves, the rubber surface can remove dust from the upper end surface of the deck 3 before cutting, and remove impurities on the upper end surface of the deck 3. Dust or impurities on the upper surface of the deck 3 may affect the focusing and energy transfer of the laser beam, resulting in deviation in the cutting position or uneven cutting surface. Dust removal can ensure that the laser beam acts accurately on the surface of the metal part, improve the cutting accuracy and quality, make the cutting edge smoother and neater, and reduce the generation of burrs and defects.

Figure 9 As shown, the fourth motor 31 is fixed at the center of the three-claw frame 30, and the three-claw frame 30 is fixed to the collection box 27 by bolts. The collection box 27 is fixed to the lower end of the support frame 25 by a support column, which is equivalent to the collection box 27 being fixed to the lower end of the support frame 25. When the support frame 25 rotates and moves, it can drive the collection box 27 to rotate and move, thereby adjusting the direction of the collection device; the collection box 28 can be slidably connected to the lower end of the collection box 27 back and forth, and there is a certain friction between the collection box 28 and the collection box 27, so that the collection box 28 is fixed to the lower end of the collection box 27 under normal conditions, and can move with the collection box 27 to collect debris. When the collection box 28 is pushed forward or backward, the collection box 28 can be separated from the collection box 27, that is, the collection box 28 is removed for disassembly and replacement; the installation and shape of the drive disk 34, the drive pin 35, and the first sleeve 36 are as shown Figure 11 and Figure 12 As shown, when the driving disk 34 rotates, the driving pin 35 can move in a circular motion, and the driving pin 35 is rotatably connected to the inner wall of the driving disk 34, which is equivalent to the first sleeve 36 being hinged on the driving disk 34, that is, when the driving disk 34 rotates, the driving pin 35 and the first sleeve 36 can move in a circular motion, and the first sleeve 36 can flip on the driving disk 34, and the two do not affect each other; the long guide rod 45 is rotatably connected to the inner wall of the first sleeve 36, and can drive the long guide rod 45 to swing when the first sleeve 36 moves in a circular motion; a brush is provided at the bottom of the sweeper 46, and the brush has a certain elasticity. When the brush is squeezed, it can bend, and when the squeezing disappears, it can recover under the action of its own elasticity; as shown Figure 14-15As shown, the square slider 54 is connected to the inner wall of the first extension plate 32 and the support sleeve 55 plays a supporting role for the ball cage universal joint 47. The upper end of the ball cage universal joint 47 is rotatably connected to the inner wall of the support sleeve 55, and the lower end is fixed to the long guide rod 45. Through the arrangement of the long guide rod 45, the support sleeve 55 and the square slider 54, it is equivalent to the long guide rod 45 being hinged to the lower end of the support sleeve 55, that is, the long guide rod 45 can swing left and right at the lower end of the support sleeve 55, and when the driving disk 34 rotates, the sweeper 46 can move in an elliptical trajectory, and when the ball cage universal joint 47 rotates, the long guide rod 45 can be driven to rotate and the sweeper 46 can swing; when the fourth motor 31 is started When the driving disc 34 is rotated, the driving pin 35 and the first sleeve 36 are moved in a circular motion. When the first sleeve 36 moves in a circular motion, the long guide rod 45 is driven to move. Since the upper end of the long guide rod 45 is hinged on the square slider 54 and the support sleeve 55, the upper end of the long guide rod 45 can drive the square slider 54 and the support sleeve 55 to move up and down. The middle part of the long guide rod 45 will follow the circular motion of the first sleeve 36 and swing. The lower end of the long guide rod 45 will drive the sweeper 46 to move in an elliptical trajectory. When the sweeper 46 moves in an elliptical trajectory, it can sweep from bottom to top along the upper end surface of the bucket 29, thereby pushing the debris on the bucket 29 out. When the sweeper 46 moves to the uppermost end of the bucket 29, the driving disc 34 continues to drive the sweeper 46 so that the sweeper 46 continues to move upward while resetting toward the head of the bucket 29. When the sweeper 46 moves toward the head of the bucket 29, the sweeper 46 will also move upward so that the brush is out of contact with the upper end surface of the bucket 29 and moves away from it, that is, it can prevent the brush from pushing back the debris when the sweeper 46 moves toward the head of the bucket 29. When the sweeper 46 moves to the head position of the bucket 29, it can move downward and upward again to push the brush back again. The debris on the movable bucket 29 falls into the collection box 27; during cleaning, through cooperation with the intermittently rotating ball cage universal joint 47, when the sweeper 46 sweeps from bottom to top along the upper end surface of the bucket 29, the ball cage universal joint 47 will not rotate. When the brush of the sweeper 46 breaks contact with the bucket 29 and moves to reset toward the head of the bucket 29, the corresponding ball cage universal joint 47 can rotate back and forth. When the ball cage universal joint 47 rotates back and forth, it can drive the long guide rod 45 to rotate back and forth. When the long guide rod 45 rotates back and forth, it can drive the sweeper 46 to swing back and forth. When the sweeper 46 swings, it can throw off the debris adhering to the upper end of the sweeper 46 under the action of inertia.

[0047] A small spur gear 48 is fixed to the upper end of the outer surface of the ball cage universal joint 47, and a small spur rack 49 is meshed on the outer surface of the small spur gear 48 and slidably connected to the square slider 54. Long pins 50 are fixed to both sides of the small spur rack 49, and guide plates 51 are fixed to the end surfaces of both sides of the first extension plate 32. The guide plates 51 are provided with a wave groove 52 and a straight groove 53 that match the long pin 50.

[0048] like Figure 14-15 As shown, the small straight rack 49 can slide left and right on the square slider 54. When the small straight rack 49 moves left and right, it can drive the small straight gear 48 and the ball cage universal joint 47 to rotate back and forth through engagement with the small straight gear 48, that is, drive the sweeper 46 to swing forward and backward; when the square slider 54 moves from top to bottom, it can drive the small straight rack 49, the small straight gear 48, the ball cage universal joint 47, the long pin 50, etc. to move from top to bottom. When the long pin 50 moves from top to bottom, it can engage with the wave groove 52, and the long pin 50 can move downward while oscillating back and forth left and right, that is, the corresponding small spur gear 48 will oscillate back and forth left and right, and when the small spur gear 48 oscillates back and forth left and right, it can drive the sweeper 46 to swing back and forth left and right. When the square slider 54 moves downward to make the long pin 50 enter the inner wall of the straight groove 53, the long pin 50 continues to follow the square slider 54 to move downward, and the long pin 50 no longer moves back and forth left and right, and under the meshing of the straight groove 53, the small spur rack 49 can be in the middle position, and the corresponding sweeper 46 is in the position as shown in FIG. Figure 9 or Figure 11 As shown, it is in a state of being parallel to the bucket 29, that is, the upper end surface of the bucket 29 can be fully cleaned at this time; through the mutual cooperation of the wave groove 52, the straight groove 53 and the long pin 50, when the sweeper 46 is out of contact with the bucket 29 and resets toward the head of the bucket 29, the long pin 50 can engage with the wave groove 52, and the engagement with the wave groove 52 can make the sweeper 46 oscillate and swing. When the sweeper 46 moves from bottom to top along the upper end surface of the bucket 29, the long pin 50 can engage with the straight groove 53, and at this time the sweeper 46 can be limited and fixed to swing, that is, the sweeper 46 can remain parallel to the bucket 29, thereby cleaning the debris on the upper end surface of the bucket 29.

[0049] The three-claw frame 30 is provided with a second extension plate 33, and the second extension plate 33 is rotatably connected to a third spur gear 39. A grinder 44 is provided at the lower end of the third spur gear 39. A third spur rack 38 slidably connected to the second extension plate 33 is meshed on the outer surface of the third spur gear 39. A first connecting rod 37 is hinged on the third spur rack 38, and the upper end of the first connecting rod 37 is rotatably connected to the driving pin 35.

[0050] like Figure 12As shown, the third spur rack 38 can slide back and forth on the second extension plate 33. When the driving disk 34 rotates, the driving pin 35 can move in a circle. The upper end of the first connecting rod 37 can move in a circle. The lower end of the first connecting rod 37 drives the third spur rack 38 to move back and forth left and right. When the third spur rack 38 moves back and forth left and right, it can drive the third spur gear 39 to rotate. When the third spur gear 39 rotates, it can drive the grinder 44 to rotate back and forth forward and reverse. After the grinder 44 contacts the deck 3, it can grind the cut deck 3. The grinder 44 is a prior art and will not be described in detail.

[0051] The inner wall at the center of the third spur gear 39 is slidably connected to a transmission shaft 41, a grinder 44 is fixed to the lower end surface of the transmission shaft 41, a pressure pad 43 is rotatably connected to the lower end of the outer surface of the transmission shaft 41, and a first spring 42 that cooperates with the pressure pad 43 is also sleeved on the outer surface of the transmission shaft 41, and an anti-slip pad 40 is fixed to the upper end of the outer surface of the transmission shaft 41.

[0052] like Figure 11-13 As shown, the transmission shaft 41 and the third spur gear 39 are spline-connected. The transmission shaft 41 can slide up and down on the inner wall of the third spur gear 39, and when the third spur gear 39 rotates, it can drive the transmission shaft 41 and the grinder 44 to rotate; one end of the first spring 42 is fixed to the lower end surface of the second extension plate 33, and the other end is fixed to the pressure pad 43. The first spring 42 always has a downward driving force on the pressure pad 43, the transmission shaft 41, and the grinder 44. Even if the grinder 44 has a downward squeezing force during grinding, the grinding effect can be improved; the anti-slip pad 40 is provided to prevent the transmission shaft 41 from being separated from the third spur gear 39 ; During operation, controlling the L-shaped seat 14 to move downward can cause the corresponding grinder 44, bucket 29, flattening roller 26, barrel cover 16, etc. to move downward synchronously. Since the grinder 44 is in the lower end position of the bucket 29, flattening roller 26, barrel cover 16, etc. under normal conditions, the grinder 44 will first contact the deck 3. When the L-shaped seat 14 continues to move downward until the bucket 29, flattening roller 26, barrel cover 16, etc. move to contact the upper end surface of the deck 3, the second extension plate 33 will squeeze the first spring 42. At this time, the first spring 42 can have a downward driving force on the grinder 44, which can improve the grinding effect when the grinder 44 is working.

[0053] When the present invention is in use, the barrel cover 16 is provided to prevent the debris from splashing to the outside when the cutting gun 15 is working, so that the debris is collected in the barrel cover 16 and falls onto the deck 3 under the action of gravity. In addition, the barrel cover 16 can collect the smoke generated during cutting, thereby reducing air pollution. After cutting, the collection device is provided to collect the debris remaining on the deck 3. The three-claw frame 30 serves as a mounting support for the drive disc 34 and the sweeper 46. When the L-shaped seat 14 moves, it can drive the collection device and the shovel to move. The bucket 29 and the collection box 27 move synchronously, and the bucket 29 can contact the upper end surface of the deck 3, that is, move along the upper end surface of the deck 3. At this time, the bucket 29 can shovel up the debris on the deck 3, and then through the provided drive disc 34, the sweeper 46, etc., the rotation of the drive disc 34 can make the sweeper 46 move along the upper end surface of the bucket 29, and can push the debris on the bucket 29 into the collection box 27 and the collection box 28. By providing a detachable collection box 28, a new collection box can be quickly replaced when the debris in the collection box 28 is full. 28; By setting up a support frame 25 that can rotate and move, the position of the collecting device can be adjusted, and when moving and cutting, the collecting device is ensured to be always at the rear end position of the cutting gun 15, that is, after the cutting gun 15 cuts the deck 3, the collecting device can collect the debris on the deck 3; traditional vacuum-type debris collection cannot collect large pieces of debris, and this device is not affected by large and small pieces of debris and can collect them in a centralized manner, thereby avoiding their accumulation on the workbench or cutting path, preventing cutting interruptions and equipment downtime adjustments caused by debris obstruction, reducing manual cleaning time, allowing cutting operations to run continuously and efficiently, and greatly improving the processing speed of hull components; the barrel cover 16 collects debris, which helps to keep the workshop clean and tidy, reduce the metal dust content in the air, and reduce smoke leakage, improve the air quality of the workshop, and reduce the risk of operators inhaling harmful dust; the debris collected by the collecting device is convenient for unified collection, classification and recycling, thereby improving the recycling rate of metal waste and reducing the production cost of the enterprise, while complying with the concept of sustainable development and achieving efficient use of resources.
