Description

Technical Field

[0001] The invention relates to the technical field of laser cutting machines, in particular to a laser cutting machine capable of adjusting multiple angles. Background Art

[0002] Laser cutting machine is a highly integrated device integrating optics, mechanics and electronics. It mainly uses a high-power density laser beam to scan the surface of the material to melt or vaporize the material, and then uses high-pressure gas to blow the molten or vaporized material away from the cut, thereby achieving the purpose of cutting the material. In the automotive manufacturing, aerospace, machinery manufacturing and other industries, it is often used to cut various metal materials, usually requiring cutting of metal sheets, pipes, etc., and then used to make precision parts.

[0003] When processing a curved pipe, a traditional laser cutting machine usually needs to place the curved pipe on a table first, fix the block on the table with bolts, and make multiple blocks press against the curved pipe. When fixing or replacing curved pipes with different radii, the bolts need to be turned repeatedly, which is cumbersome and inefficient. The bent pipes to be processed are often directly fixed on the table through a block. However, during the laser cutting process, since the shapes or sizes of the processed bent pipes are different, when the cutting angle of the bent pipe needs to be adjusted, the bent pipe needs to be removed from the table, adjusted, and then fixed, which results in a cumbersome operation process and poor flexibility. During cutting, the laser cutting head is usually driven by a driving component to move horizontally or vertically, thereby achieving cutting of different positions of the bent pipe. However, when it is necessary to cut the side of the bent pipe or other special angles, it is necessary to repeatedly manually adjust the position of the laser cutting head or the bent pipe, which has poor flexibility, resulting in low cutting efficiency and poor practicality.

[0023] like Figure 2-Figure 4As shown, a laser cutting machine with multiple angle adjustments described in the present invention includes an operating table 1, a rotating structure 2 installed on the operating table 1, a fixed structure 3 provided on the rotating structure 2, a clamping structure 4 connected to the fixed structure 3, a movable structure 5 installed on the operating table 1, an adjustment structure 6 provided on the movable structure 5, and a connecting structure 7 matched with the adjustment structure 6; the fixed structure 3 includes four mounting blocks 301 and a guide rod 302 fixedly connected between two adjacent mounting blocks 301, the rotating structure 2 is matched with a mounting block 301, two driving frames 303 are slidably connected between the two guide rods 302, the bottom surface of the driving frame 303 is fixedly connected with a first connecting frame 304, and the ends of the two driving frames 303 are fixedly connected with a connecting block 305, the rotating structure 2 is provided with two hydraulic cylinders 306, the telescopic ends of the two hydraulic cylinders 306 are respectively fixedly connected to the two connecting blocks 305, and the first connecting frame 304 is matched with a clamping structure 306. The two drive frames 303 are symmetrically arranged, and the drive frames 303 and the first connecting frame 304 are both in a "U"-shaped structure. The four fixing blocks 402 are in contact with the bent pipe 9. After the adjustment of the clamp angle is completed, the bent pipe 9 needs to be fixed on the turntable 208 through the clamp 9, and the bent pipe 9 is placed at the center of the turntable 208. At this time, the two hydraulic cylinders 306 on both sides simultaneously drive the two drive frames 303 to slide toward the center position through the connecting block 305 until the drive frames 303 bring The first connecting frame 304 at the bottom is moved to a suitable position. At the same time, since the two ends of the driving frame 303 are respectively slidably connected with the two guide rods 302, and the guide rods 302 are fixed on the turntable 208 through the mounting blocks 301, the stability of the driving frame 303 during the sliding process is improved, and the firmness is enhanced. At the same time, the two hydraulic cylinders 306 drive the two first connecting frames 304 to continue to move toward the center position until the four fixing blocks 402 clamp the bent pipe 9. At this time, the fixation of the bent pipe 9 is completed, and the firmness is strong.

[0024] Specifically, Figure 2-Figure 4As shown, the clamping structure 4 includes four connecting rods 401 and a fixing block 402 fixedly connected to the end of the connecting rod 401, two connecting rods 401 are provided on the two first connecting frames 304, two sliding grooves 403 are provided on the first connecting frame 304, the connecting rod 401 and the sliding groove 403 are slidably connected, a guide frame 404 is fixedly connected to the first connecting frame 304, one end of the connecting rod 401 away from the fixing block 402 is slidably connected to the guide frame 404, two limiting rings 406 are threadedly connected to the guide frame 404, the limiting ring 406 and the end of the connecting rod 401 are in conflict with each other, a tension spring 405 is fixedly connected between the ends of two adjacent connecting rods 401, and the guide frame 404 is in a "U" shape. Then it is necessary to adjust the guide frame 404 according to the needs of the invention. The radius of the curved pipe is adjusted to adjust the positions of the four fixed blocks 402. First, the four limit rings 406 are rotated in sequence to the end positions of the guide frame 404. At this time, under the resetting action of the tension spring 405, the connecting rod 401 drives the four fixed blocks 402 to move to the center position of the turntable 208. Then, the bottom of the curved pipe 9 is aligned with the center of the four fixed blocks 402 and inserted downward, so that the four connecting rods 401 move to both sides along the slide groove 403 until the bottom of the curved pipe 9 is located between the four fixed blocks 402. Then, the four limit rings 406 are rotated in reverse in sequence to make the limit rings 406 contact the ends of the connecting rods 401, thereby driving the inclined surfaces of the four fixed blocks 402 to press against the curved pipe 9. At the same time, it is convenient to adapt to curved pipes 9 of different radii by adjusting the positions of the four fixed blocks 402, which is highly practical.

[0025] Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the rotating structure 2 includes a base 201 and a central shaft 202 fixedly connected to the center of the base 201, the operating table 1 is fixedly connected to the base 201, the top of the central shaft 202 is fixedly connected to the first gear 203, the central shaft 202 is rotatably connected to a docking block 204, the interior of the docking block 204 is rotatably connected to a rotating shaft 205, the rotating shaft 205 is fixedly connected to a second gear 206, the second gear 206 is meshed with the first gear 203, a turntable 208 is engaged with the docking block 204, the turntable 208 is rotatably connected to the base 201, the inner wall of the turntable 208 is slidably connected to the rotating shaft 205, a driving hole 207 is opened on the top surface of the rotating shaft 205, the docking block 204 is a hexagonal structure, four mounting blocks 301 are fixedly connected to the turntable 208, and two hydraulic cylinders 306 are fixedly connected to the turntable 208; before cutting the bent pipe 9, It is necessary to preliminarily adjust the angle of the turntable 208 and the clamp on the operating table 1 according to factors such as the cutting shape and direction, thereby avoiding the need to significantly adjust the angle of the cutting head 8 during cutting and improving the cutting efficiency. It is only necessary to first engage the turntable 208 with the clamp installed on the hexagonal docking block 204, then insert the hexagonal wrench into the driving hole 207, and rotate the hexagonal wrench, thereby driving the rotating shaft 205 to rotate inside the docking block 204, and at the same time, the rotating shaft 205 drives the second gear 206 to rotate. Since the second gear 206 and the first gear 203 are meshed with each other, during the process of rotating the hexagonal wrench, the rotating shaft 205 drives the docking block 204 to make a circular motion around the central axis 202. At this time, the turntable 208 drives the clamp to rotate a certain angle, which is beneficial to the subsequent cutting of the curved pipe 9 and avoids significantly adjusting the angle of the cutting head 8. At the same time, after the turntable 208 is removed from the base 201, it is convenient to add lubricating oil to the internal parts, which is highly practical.

[0026] Specifically, Figure 1 , Figure 6-Figure 8 and Fig.10As shown, the mobile structure 5 includes a mounting frame 501 and a first guide rail 502 fixedly connected to the top surface of the mounting frame 501, the mounting frame 501 is fixedly connected to the edge of the operating table 1, the side of the mounting frame 501 is fixedly connected to the second guide rail 503, a first mounting plate 504 is slidably connected between the first guide rail 502 and the second guide rail 503, a first motor 508 is fixedly connected to the back side of the first mounting plate 504, a third gear 506 is fixedly connected to the output shaft of the first motor 508, a first rack 507 is fixedly connected to the top surface of the mounting frame 501, and the third gear 506 and the first rack 507 mesh with each other The mounting frame 501 is equipped with a first drag chain 505; in the process of cutting the curved pipe 9 by the cutting head 8, the cutting head 8 realizes lateral movement through the first mounting plate 504 and the mounting frame 501, and the first motor 508 located on the back side of the first mounting plate 504 drives the third gear 506 to rotate. Since the third gear 506 is engaged with the first rack 507, the first mounting plate 504 is driven to move laterally between the first guide rail 502 and the second guide rail 503, thereby realizing the lateral movement of the cutting head 8, and the power cord on the first motor 508 runs through the first drag chain 505, avoiding the problem of multiple power cords being entangled with each other, and the practicability is strong.

[0027] Specifically, Figure 1 and Figure 6-Figure 10As shown, the adjustment structure 6 includes a third guide rail 601 and four sliders 602 slidably connected to the third guide rail 601, two third guide rails 601 are fixedly connected to the first mounting plate 504, a connecting plate 603 is fixedly connected between the four sliders 602, a second motor 604 is fixedly connected to the connecting plate 603, a fourth gear 605 is fixedly connected to the output shaft of the second motor 604, a second rack 606 is provided between the two third guide rails 601, the second rack 606 is fixedly connected to the first mounting plate 504, the fourth gear 605 is meshed with the second rack 606, a second drag chain 607 is installed on the connecting plate 603, a second connecting frame 608 is fixedly connected to the connecting plate 603, a hydraulic rod 609 is fixedly connected to the interior of the second connecting frame 608, a telescopic end of the hydraulic rod 609 is fixedly connected to the second mounting plate 610, and the second The mounting plate 610 is slidably connected to the second connecting frame 608; when the cutting head 8 needs to move up and down during cutting, the second motor 604 fixed on the connecting plate 603 drives the fourth gear 605 to rotate. Since the fourth gear 605 is meshed with the second rack 606 on the first mounting plate 504, the connecting plate 603 and the inner slider 602 are driven to move up and down along the two third guide rails 601. At this time, the cutting head 8 can be moved up and down for cutting, which has strong flexibility. The power cord connected to the second motor 604 runs through the second drag chain 607, and the second drag chain 607 has a strong protection ability for the power cord. When the cutting head 8 needs to move forward and backward, since the second connecting frame 608 installed on the connecting plate 603 is provided with a hydraulic rod 609 inside, the telescopic end of the hydraulic rod 609 drives the second mounting plate 610 to move forward and backward, and then the second mounting plate 610 drives the cutting head 8 to move forward and backward for cutting, which is easy to operate.

[0028] Specifically, Figure 1 , Figure 6 , Figure 8 and Fig. 9As shown, the connecting structure 7 includes a first support frame 701 and a third motor 702 fixedly connected to the first support frame 701, the first support frame 701 is fixedly connected to the side wall of the second mounting plate 610, the second support frame 703 is fixedly connected to the output shaft of the third motor 702, the fourth motor 704 is fixedly connected to the second support frame 703, the output shaft of the fourth motor 704 is fixedly connected to a fixing frame 705, the end of the fixing frame 705 is a "U"-shaped structure, and the cutting head 8 is fixedly connected to the fixing frame 705; when cutting the special angle of the curved pipe 9, the third motor 702 installed on the first support frame 701 drives the second support frame 703 to rotate 360 ​​degrees in the horizontal direction, and at the same time cooperates with the fourth motor 704 on the second support frame 703 to drive the fixing frame 705 and the cutting head 8 to rotate 360 ​​degrees in the vertical direction. At this time, the cutting angle of the cutting head 8 is effectively increased, thereby improving practicality.

[0029] When the present invention is in use, before cutting the curved pipe 9, it is necessary to preliminarily adjust the angle of the turntable 208 and the clamp on the operating table 1 according to factors such as the cutting shape and direction, thereby avoiding the need to significantly adjust the angle of the cutting head 8 during cutting and improving the cutting efficiency. It is only necessary to first engage the turntable 208 with the clamp on the hexagonal docking block 204, then insert the hexagonal wrench into the driving hole 207, and rotate the hexagonal wrench to drive the rotating shaft 205 to rotate inside the docking block 204. At the same time, the rotating shaft 205 drives the second gear 206 to rotate. Since the second gear 206 and the first gear 203 are meshed with each other, during the process of rotating the hexagonal wrench, the rotating shaft 205 drives the docking block 204 to make a circular motion around the central axis 202. At this time, the turntable 208 drives the clamp to rotate a certain angle, which is beneficial to the subsequent cutting of the curved pipe 9 and avoids significantly adjusting the angle of the cutting head 8. At the same time, after the turntable 208 is taken out from the base 201, it is convenient to add lubricating oil to the internal parts, which is highly practical. After completing the adjustment of the clamp angle, it is then necessary to fix the curved pipe 9 on the turntable 208 through the clamp, and place the curved pipe 9 at the center of the turntable 208. At this time, the two hydraulic cylinders 306 on both sides simultaneously drive the two driving frames 303 to slide toward the center position through the connecting blocks 305, until the driving frame 303 drives the first connecting frame 304 at the bottom to move to a suitable position. At the same time, since the two ends of the driving frame 303 are respectively slidably connected with the two guide rods 302, and the guide rods 302 are fixed on the turntable 208 through the mounting blocks 301, the stability of the driving frame 303 during the sliding process is improved, and the firmness is enhanced. Then, it is necessary to adjust the position of the four fixing blocks 402 according to the radius of the curved pipe 9. First, the four limit rings 406 are rotated to the end position of the guide frame 404 in sequence. At this time, when the tension spring 405 is retracted, Under the action of the positioning, the connecting rod 401 drives the four fixing blocks 402 to move to the center position of the rotating disk 208, and then the bottom of the curved pipe 9 is aligned with the center of the four fixing blocks 402 and inserted downward, so that the four connecting rods 401 move to both sides along the slide groove 403 until the bottom of the curved pipe 9 is located between the four fixing blocks 402, and then the four limiting rings 406 are rotated in the opposite direction in sequence, so that the limiting rings 406 contact the ends of the connecting rods 401, thereby driving the inclined surfaces of the four fixing blocks 402 to press against the curved pipe 9, and at the same time, the two hydraulic cylinders 306 drive the two first connecting frames 304 to continue to move toward the center position until the four fixing blocks 402 clamp the curved pipe 9, at which time the fixing of the curved pipe 9 is completed, and the firmness is strong. At the same time, it is convenient to adapt to the curved pipes 9 of different radii by adjusting the positions of the four fixing blocks 402, and it is highly practical. In the process of cutting the curved pipe 9 by the cutting head 8, the cutting head 8 realizes lateral movement through the first mounting plate 504 and the mounting frame 501. At this time, the first motor 508 located on the back side of the first mounting plate 504 drives the third gear 506 to rotate. Since the third gear 506 is engaged with the first rack 507, the first mounting plate 504 is driven to move horizontally between the first guide rail 502 and the second guide rail 503, thereby realizing the lateral movement of the cutting head 8. The power cord on the first motor 508 runs through the first drag chain 505, avoiding the problem of multiple power cords being entangled with each other, and the practicality is strong. When the cutting head 8 needs to move up and down during cutting, the second motor 604 fixed on the connecting plate 603 drives the fourth gear 60 5 rotates, and the fourth gear 605 and the second rack 606 on the first mounting plate 504 are meshed with each other, thereby driving the connecting plate 603 and the inner slider 602 to move up and down along the two third guide rails 601, and then the cutting head 8 can be moved up and down for cutting, which has strong flexibility, and the power line connected to the second motor 604 runs through the second drag chain 607, and the second drag chain 607 has a strong protection ability for the power line. When the cutting head 8 needs to move forward and backward, since the second connecting frame 608 installed on the connecting plate 603 is provided with a hydraulic rod 609 inside, the telescopic end of the hydraulic rod 609 drives the second mounting plate 610 to move forward and backward, and then the second mounting plate 610 drives the cutting head 8 to move forward and backward for cutting, which is easy to operate; When cutting the special angle of the curved pipe 9, the third motor 702 installed on the first support frame 701 drives the second support frame 703 to rotate 360 ​​degrees in the horizontal direction, and at the same time cooperates with the fourth motor 704 on the second support frame 703 to drive the fixed frame 705 and the cutting head 8 to rotate 360 ​​degrees in the vertical direction. At this time, the cutting angle of the cutting head 8 is effectively increased, and the practicality is improved.
