Description

Technical Field

[0001] This invention relates to the field of workpiece support technology for laser cutting robots, specifically a support mechanism based on a cutting robot. Background Technology

[0002] A laser cutting robot is a modern processing equipment that uses a high-energy-density laser beam as a cutting tool. Its working principle is to generate a laser by a laser generator, which is focused into an extremely small spot by an optical system, causing the material in the irradiated area to melt, vaporize or reach the ignition point instantly. The molten residue is then completely blown away by a synchronously jetted high-speed airflow, thereby achieving precise cutting of the workpiece.

[0003] In the existing technology, in the process of batch processing of profiles by laser cutting robots, in order to ensure processing accuracy, it is generally necessary to use a limiting support mechanism to reliably position and fix the profiles, so as to effectively suppress the vibration or displacement that may occur in the profiles during processing, and ensure the consistency and stability of the forming quality of the same batch of profiles during continuous processing.

[0004] However, the support mechanisms used to support and limit profiles in traditional laser cutting processes have the following problems: 1. In existing technologies, the profile support mechanisms equipped on laser cutting robots can usually only provide effective support for profiles with a limited number of cross-sectional shapes and fixed specifications. When facing the processing needs of profiles with different cross-sectional shapes and multiple specifications, special tooling must be changed to achieve the limiting support of different profiles. This not only significantly extends the production preparation time and reduces the overall utilization efficiency of the equipment, but also makes it difficult for the entire cutting and processing system to adapt to the production requirements of small batches and rapid switching of multiple varieties; 2. In existing technologies, when performing multi-face cutting on profiles with complex cross-sections such as U-shaped steel and H-shaped steel, since these profiles usually need to be cut in different spatial orientations such as the web and flanges, the existing support mechanisms can generally only fix the profile in a single processing state. This means that when changing the processing surface, the fixture may need to be changed again, which not only interrupts the continuous laser cutting process and shortens the effective working time of the equipment, but also further affects the overall cutting and processing efficiency. Summary of the Invention

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1 A support mechanism 4 based on a cutting robot includes a base plate 1 and a laser cutting device 5 disposed on the outside of the base plate 1. The laser cutting device 5 consists of a drive assembly for vertical, horizontal, and rearward and left-right conveying and adjustment, and a laser cutting emitter mounted on the drive assembly. An adjustment mechanism 2 is disposed on the upper side of the base plate 1, and a conversion mechanism 3 and a support mechanism 4 are disposed on the adjustment mechanism 2.

[0037] Please see Figure 1 and Figure 2 The adjustment mechanism 2 includes a support adjustment part 21 disposed on the upper side of the base plate 1 for front-to-back movement adjustment, a lifting adjustment part 22 disposed on the support adjustment part 21 for up-to-down movement adjustment, and a limit adjustment part 23 disposed on the lifting adjustment part 22.

[0038] Please see Figure 2 and Figure 3 The support adjustment part 21 includes a fixed platform 211 symmetrically fixed on the upper side of the rear end of the base plate 1. A guide rail 212 extending forward and backward is symmetrically fixed on the upper side of the base plate 1 and in front of the fixed platform 211. An electric slider 213 that moves forward and backward is slidably arranged on the guide rail 212.

[0039] Please see Figure 2 , Figure 3 and Figure 4 The lifting adjustment unit 22 includes fixed frames 221 that are symmetrically distributed front and back and fixedly mounted on the upper sides of two fixed platforms 211 and two electric sliders 213 respectively. Support platforms 222 are fixedly mounted on the upper side of the opposite end of the two fixed frames 221, and cylinders 223 are fixedly mounted on the lower side of the opposite end of the two fixed frames 221.

[0040] Please see Figure 2 , Figure 3 and Figure 4 The limiting adjustment part 23 includes a limiting frame 231 fixedly installed at the telescopic end of the cylinder 223 and moving up and down. The lower side of the limiting frame 231 is symmetrically fixed with guide rods that are slidably connected to the corresponding fixed frame 221. The limiting frame 231 is provided with a limiting slide groove 232 that runs through the front and back. The upper end of the opposite side of the two limiting frames 231 is fixedly provided with a damping pad 233.

[0041] The cylinder 223 can drive the corresponding limit frame 231 to move up and down for adjustment; the electric slider 213 can drive the front fixed frame 221 to move back and forth along the guide rail 212 for adjustment, and the fixed frame 221 will then drive the corresponding cylinder 223 and the limit frame 231 to move back and forth synchronously for adjustment.

[0042] Please see Figure 1 and Figure 2 The conversion mechanism 3 includes a conversion limiting part 31 disposed on the limiting adjustment part 23 for converting and adjusting the support and limiting of profiles with different cross sections and specifications. The limiting adjustment part 23 is provided with a driving adjustment part 32 for driving the conversion limiting part 31 to move and adjust, and a driven conversion part 33 for synchronously converting and adjusting the support and limiting of the profile with the conversion limiting part 31. The conversion limiting part 31 and the driven conversion part 33 are jointly provided with a docking adjustment part 34 to ensure that the two are adjusted synchronously.

[0043] Please see Figure 2 , Figure 4 and Figure 5 The conversion limiting part 31 includes multiple limiting platforms 311 that are evenly arranged on the left and right sides in front of the rear limiting frame 231 and on the upper side of the corresponding support platform 222. Each limiting platform 311 has a wedge-shaped block structure and multiple balls are evenly rolled on its lower side. The two adjacent limiting platforms 311 are symmetrically distributed. A sliding frame 312 that is slidably connected to the corresponding limiting slide groove 232 is fixedly arranged on the rear side of the limiting platform 311. A threaded groove 313 that runs through the left and right sides is opened at the rear end of the sliding frame 312.

[0044] Please see Figure 2 , Figure 5 and Figure 6The drive adjustment unit 32 includes a motor 321 fixedly mounted on the right side of the rear limit frame 231 via a support 1. A rotating shaft 322 is symmetrically mounted on the rear side of the rear limit frame 231 via a support 2. The right rotating shaft 322 is fixedly connected to the drive end of the motor 321. A plurality of threaded rods 323 are symmetrically distributed between the two rotating shafts 322. The threaded rods 323 correspond to the limit platform 1 311 and are threadedly connected to the corresponding threaded grooves 313.

[0045] When the limiting platform 311 needs to be moved left or right for adjustment, the motor 321 drives the corresponding rotating shaft 322 to rotate in a specific direction. The rotating shaft 322 then drives each threaded rod 323 to rotate synchronously. The threaded rods 323 then drive the sliding frame 312 and the limiting platform 311 to move left or right along the corresponding limiting groove 232 through the helical transmission with the corresponding threaded groove 313. Since the adjacent threaded rods 323 are symmetrically distributed, by driving each threaded rod 323 to rotate forward or in reverse by the motor 321, two adjacent limiting platforms 311 on the vertical plane can move synchronously relative to each other, that is, two adjacent limiting platforms 311 on the inclined plane can move synchronously away from each other; or two adjacent limiting platforms 311 on the inclined plane can move synchronously relative to each other, that is, two adjacent limiting platforms 311 on the vertical plane can move synchronously away from each other.

[0046] Please see Figure 2 and Figure 7 The driven conversion part 33 includes a second limiting platform 331 with the same shape as the first limiting platform 311 and corresponding to the first limiting platform 311, which is provided on the rear side of the front limiting frame 231. Multiple balls are also evenly rolled on the lower side of the second limiting platform 331. The balls can greatly reduce the frictional resistance between the first limiting platform 311 and the second limiting platform 331 and the upper surface of the corresponding support platform 222. A second sliding frame 332 that is slidably connected to the corresponding limiting slide groove 232 is fixedly provided on the front side of the second limiting platform 331.

[0047] Please see Figure 2 and Figure 7 The docking adjustment part 34 includes a docking link 341 that is symmetrically fixed on the front side of the rear limiting frame 231 and slides through the front limiting frame 231. A docking link 342 that slides through the corresponding limiting platform 231 and sliding frame 232 is fixed on the front side of the limiting platform 311.

[0048] When the threaded rod 323 drives the corresponding limiting platform 311 to move left and right for adjustment, the limiting platform 311 drives the corresponding docking link 342 to move and adjust synchronously. The docking link 342 then drives the corresponding limiting platform 331 and the sliding frame 332 to move and adjust synchronously left and right along the corresponding limiting groove 232.

[0049] When the cylinder 223 moves the limiting frame 231 up and down, the connecting rod 341 ensures that the two limiting frames 231 move up and down synchronously. At the same time, the connecting rod 342 further ensures that the limiting platform 311 and the limiting platform 331, which move up and down synchronously with the corresponding limiting frame 231, also move up and down synchronously. This ensures the stability and consistency of the limiting platform 311 and the limiting platform 331 in supporting and limiting the profile. When the electric slider 213 moves the front limiting frame 231 and each limiting platform 331 on it back and forth, the front limiting frame 231 slides back and forth along the connecting rod 341, and the limiting platform 331 slides back and forth synchronously along the corresponding connecting rod 342.

[0050] When supporting and limiting the circular tube, the motor 321 drives the threaded rod 323 to rotate in a directional manner, causing the two adjacent limiting platforms 311 on the inclined surface to move synchronously relative to each other by a certain distance. The limiting platform 331, under the action of the connecting rod 342, moves synchronously and adjusts until the front and rear ends of the circular tube can be stably placed in the V-shaped grooves formed by the two adjacent limiting platforms 311 and 331 respectively. Thus, the corresponding limiting platforms 311 and 331 can temporarily limit the front and rear ends of the circular tube, and the corresponding support platform 222 provides stable support for the limiting platforms 311 and 331. Then, the electric slider 213 drives the front fixing frame 221 and limiting frame 231 to move backward until the damping pads 233 on the front and rear limiting frames 231 stably press and adhere the corresponding ends of the circular tube, thereby synchronously and stably supporting and fixing multiple circular tubes (e.g., Figure 10 (As shown).

[0051] When supporting and limiting the square tube, first place the square tube between two adjacent limiting platforms 311 and corresponding limiting platform 331 on the vertical plane, and place both ends of the square tube on the corresponding support platforms 222. Then, drive the threaded rod 323 to rotate in a direction via motor 321, causing the two adjacent limiting platforms 311 on the vertical plane to move synchronously relative to each other a certain distance. Simultaneously, drive the front fixing frame 221 and limiting frame 231 to move synchronously backward a certain distance via electric slider 213, until the damping pads 233 on the front and rear limiting frames 231 stably and firmly press the corresponding ends of the square tube. Furthermore, the corresponding limiting platforms 311 and 331 simultaneously and stably press the left and right sides of the square tube through the vertical section, thereby synchronously and stably supporting and fixing multiple square tubes (e.g., Figure 11 (As shown).

[0052] When supporting and limiting the T-shaped steel, the threaded rod 323 is first driven by the motor 321 to rotate in a directional manner, causing the two adjacent limiting platforms 311 and their corresponding two limiting platforms 331 on the vertical plane to move synchronously relative to each other a certain distance until the vertical section of the T-shaped steel can be stably inserted between the two adjacent limiting platforms 311 and 331 on the vertical plane. The two support platforms 222 then stably support the lower end of the vertical section of the T-shaped steel. Then, the limiting frame 231 and the corresponding limiting platforms 311 and 331 are driven by the cylinder 223 to move upward until the upper end of the corresponding limiting platform 311 and 331 is about to connect with the horizontal section of the corresponding T-shaped steel. The contact allows the limiting platform 311 and the limiting platform 331 to stably and temporarily limit the vertical section of the T-shaped steel. Then, the motor 321 drives the two adjacent limiting platforms 311 and 331 on the vertical surface to move synchronously relative to each other. At the same time, the electric slider 213 drives the front fixing frame 221 and the limiting frame 231 to move backward synchronously until the damping pads 233 on the front and rear limiting frames 231 stably and firmly press the corresponding ends of the T-shaped steel. The corresponding limiting platforms 311 and 331 simultaneously and stably press the left and right sides of the vertical section of the T-shaped steel through the vertical section, thereby synchronously and stably supporting and fixing multiple T-shaped steels (such as...). Figure 12 (As shown).

[0053] When supporting and limiting the horizontal web of an H-beam, the threaded rod 323 is first rotated directionally by motor 321, causing the two adjacent limiting platforms 311 and their corresponding two limiting platforms 331 to move synchronously and backwards a certain distance until the H-beam can be placed outside the corresponding limiting platforms 311 and 331, and the vertical flanges of the H-beam can fit against the vertical sections of the corresponding limiting platforms 311 and 331. Thus, the front and rear ends of the H-beam web can be temporarily limited by the corresponding limiting platforms 311 and 331, and the corresponding support platform 2... 22 provides stable support for limiting platform 1 311 and limiting platform 2 331. Then, motor 321 drives two adjacent limiting platforms 1 311 and two limiting platforms 2 331 on the inclined plane to move synchronously in opposite directions. At the same time, electric slider 1 213 drives the front fixing frame 221 and limiting frame 231 to move synchronously backward until the damping pads 233 on the front and rear limiting frames 231 stably and tightly adhere and press the corresponding ends of the H-beams. The corresponding limiting platforms 1 311 and limiting platforms 2 331 synchronously and stably adhere and press the inner side of the vertical flange of the H-beams through the vertical section, thereby synchronously and stably supporting and fixing multiple H-beams (e.g. Figure 13 (As shown).

[0054] The above-described operation method enables the rapid adjustment and conversion of the structure to adapt to the limiting support of various cross-sectional shapes such as round tubes, square tubes, T-shaped steel, and H-shaped steel. It can also adapt to different specifications and sizes of profiles under the same cross-sectional type, thereby significantly reducing the need for frequent changes of special tooling in traditional processing, greatly shortening the preparation time when changing products, effectively improving equipment utilization efficiency and production continuity, and enabling the entire laser cutting processing system to quickly adapt to the manufacturing needs of multiple varieties and small batches.

[0055] When supporting and limiting the horizontal flange at the top of an H-beam, first place the H-beam between two adjacent vertical limiting platforms 311 and corresponding limiting platform 331. Then, place the two ends of the horizontal flange at the bottom of the H-beam on the corresponding support platforms 222. Next, drive the threaded rod 323 to rotate in a directional manner via motor 321, causing the two adjacent vertical limiting platforms 311 to move synchronously relative to each other. Finally, drive each limiting platform 311 and limiting platform 331 upward via cylinder 223. Simultaneously, the electric slider 213 drives the front fixing frame 221 and the limiting frame 231 to move backward synchronously until the damping pads 233 on the front and rear limiting frames 231 stably and tightly press the corresponding ends of the H-beams. At the same time, the corresponding limiting platforms 311 and 331 simultaneously and stably press the left and right sides of the vertical web of the H-beams through the vertical section, and the upper ends of the limiting platforms 311 and 331 are about to contact the horizontal flange at the upper end of the H-beams, thereby synchronously and stably supporting and fixing multiple H-beams (e.g. Figure 14 (As shown).

[0056] The above-mentioned operation method can also be used to flexibly adapt to the positioning requirements of complex cross-section profiles such as H-beams under different processing conditions by quickly adjusting and converting the structure. This achieves stable limiting support and laser cutting processing of multiple processing surfaces of the same profile, effectively avoids production interruptions caused by changing fixtures in traditional processing, and further significantly improves the overall processing efficiency of complex cross-section profiles.

[0057] Please see Figure 1 and Figure 2 The support mechanism 4 includes an adjustment support part 41 that is mounted on the support adjustment part 21 and moves back and forth to support the middle part of the profile. The adjustment support part 41 is provided with a lifting support part 42 that moves up and down to support the profile.

[0058] Please see Figure 2 and Figure 8The adjustment support part 41 includes an electric slider 2 411 that is slidably mounted on the guide rail 212 and moves back and forth. The electric slider 2 411 is located behind the electric slider 1 213. The upper side of the two electric sliders 2 411 is fixedly mounted on a moving platform 412. The upper side of the moving platform 412 is evenly rotated left and right by a support 3 and multiple sets of support rollers 413 are mounted. Each set consists of multiple support rollers 413 evenly distributed back and forth. The highest point of the upper end of the support roller 413 is flush with the upper surface of the support platform 222.

[0059] When the flanges of square tubes, T-shaped steel, or H-shaped steel are stably supported and fixed by limiting platform 1 311 and limiting platform 2 331, the middle position of the fixed square tubes, T-shaped steel, or H-shaped steel can be reinforced and supported by the corresponding support rollers 413, thereby preventing the square tubes, T-shaped steel, or H-shaped steel from bending and deforming during processing. At the same time, the moving platform 412 and the support rollers 413 can be moved back and forth and adjusted by the electric slider 2 411, thereby quickly changing the support position of the support rollers 413 on the corresponding profiles.

[0060] Please see Figure 2 , Figure 8 and Figure 9 The lifting support part 42 includes a plurality of cylinders 421 that are evenly fixed on the lower side of the moving platform 412. Each cylinder 421 and each set of support rollers 413 are staggered. The telescopic end of the cylinder 421 is fixedly provided with a U-shaped lifting frame 422 that moves up and down. A support wheel 423 is rotatably provided on the U-shaped lifting frame 422.

[0061] When the web of the round tube or H-beam is stably supported and fixed by the first limiting platform 311 and the second limiting platform 331, the second cylinder 421 drives the U-shaped lifting frame 422 and the support wheel 423 to move upward until the support wheel 423 makes stable contact with the web of the round tube or H-beam, thereby preventing the round tube or H-beam from bending and deforming during processing. At the same time, the second electric slider 411 can drive the moving platform 412 and the second cylinder 421 to move back and forth for adjustment, thereby quickly changing the support position of the support wheel 423 on the corresponding profile.

[0062] When performing batch laser cutting on profiles, multiple profiles are first stably supported and fixed by limiting stage 1 311 and limiting stage 2 331. Then, the laser cutting emitter is moved and adjusted by the drive assembly of the up-down, front-back and left-right conveying adjustment on the laser cutting equipment 5 to continuously and rapidly cut the fixed profiles in batches.

[0063] It should be noted that existing technologies can also stably support and fix profiles with one or two specific cross-sectional shapes and single-size specifications using specialized support fixtures. Although this is technically easier to implement and simpler to operate, it only solves the support problem for a limited number of cross-sectional types and single-size profiles. When stably supporting and limiting profiles with multiple cross-sectional shapes and different sizes, this existing technology still requires changing and disassembling the support fixture, resulting in high initial investment costs for the support fixture, long production downtime, and low efficiency. However, in the solution of this invention, the conversion limiting part 31 and the driven conversion part 33, through structural conversion adjustment and in conjunction with the adaptive adjustment of the support mechanism 4, can achieve stable support and limiting for profiles with multiple cross-sectional shapes and different sizes. This significantly reduces the need for frequent changes of specialized tooling in traditional processing and greatly improves the production line's ability to quickly change between different cross-section profiles, providing effective technical support for multi-variety, small-batch production. Furthermore, the adjustment mechanism 2 and conversion mechanism 3 added to this solution compared to existing support tooling are all conventional mechanical components, without any high-cost precision parts. They require only a one-time investment for long-term use, thus the cost of adding these structures is low. Compared to the significant reduction in equipment and warehousing management costs and the increased production efficiency from rapid changeover, the cost of adding these structures is negligible.
