[0022] The present invention provides a fully automatic laser cutting and welding device. It has the following beneficial effects:

[0023] 1. The present invention drives the driving shaft to rotate through a servo motor, and further realizes the automatic feeding effect of the tubular workpiece through the synchronous rotation of multiple dividing plates and the cooperation of the first feeding port and the second feeding port, which can greatly reduce manual intervention, speed up the production rhythm and improve the overall work efficiency.

[0024] 2. The present invention can quickly adapt to workpieces of different specifications by adding a fixed self-check, thus reducing the adjustment time. Secondly, the fixed component can clamp the workpiece more stably, and the stable clamping can ensure the accuracy during the cutting or welding process, reduce the risk of workpiece deformation or dislocation, and thus improve product quality.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example:

[0037] Please refer to the attached Figure 1 - Attachment Figure 8 The embodiment of the present invention provides a fully automatic laser cutting and welding device, including: a body 1, which serves as a support carrier of the entire device, and a plurality of mechanisms are arranged inside the body to ensure the normal operation of the laser welding:

[0038] A welding assembly, which is mounted on the inner top wall of the body 1 and is used for laser cutting and welding of workpieces;

[0039] Specifically, the component not only has a high-power laser source, but also is equipped with an intelligent control system to adjust the laser parameters in real time to ensure the consistency of welding quality and workpiece.

[0040] A driving assembly, which is installed outside the welding assembly and is used to move the welding assembly;

[0041] Specifically, the drive assembly is located outside the welding assembly, and the electric guide rail is used to drive the movement of the welding assembly, which can achieve rapid positioning and switching, greatly improving production efficiency. In addition, the drive assembly can ensure that it remains stable when processing complex workpieces.

[0042] A fixing assembly, which is arranged inside the machine body 1 and is used to clamp and fix the workpiece;

[0043] Specifically, the fixing assembly can adapt to workpieces of different shapes and sizes, effectively preventing displacement during the welding process, thereby improving processing accuracy and safety.

[0044] The automatic loading assembly starts the driving motor 503 to rotate the driving shaft 512, and further drives the multiple dividing plates 513 to rotate synchronously. At this time, the tubular workpiece located on the outer surface of the support frame 2 enters the cavity between the two dividing plates 513 through the first feeding port 505 under the action of gravity, and is discharged at the second feeding port 511 as the dividing plates 513 rotate. After that, the workpiece is transported by the unloading plate 515 and lands on the outer surface of the placing plate 514. In this way, automatic loading is realized, which can greatly reduce manual intervention, speed up the production rhythm, and improve the overall work efficiency;

[0045] In addition, by starting the servo motor 506, the swing plate 509 is driven to rotate, which drives one end of the traction rod 508 to swing. Under the traction force of the traction rod 508, the two movable plates 510 are driven to rotate, so that the mounting block 507 moves along the inner wall of the slide groove 501, and then drives the two positioning plates 502 to move synchronously, thereby ensuring that the loading assembly set by the present invention can load tubular workpieces of the same length, which greatly improves the flexibility of use of the device.

[0046] Specifically, this component can quickly and accurately deliver raw materials to the processing area, reducing manual intervention, optimizing the production process, and significantly improving overall work efficiency.

[0047] The automatic feeding assembly includes a support frame 2, which is fixedly mounted on the outside of the machine body 1, and a servo motor 506 is installed inside the support frame 2. The output end of the servo motor 506 is fixedly connected to a swing plate 509, and the outer eccentric part of the swing plate 509 is rotatably connected to two traction rods 508. The other end of the traction rod 508 is rotatably connected to a moving plate 510, and the top of the moving plate 510 is fixedly connected to two mounting blocks 507. The upper surface of the support frame 2 is provided with two slide grooves 501, and the top of the mounting block 507 is fixedly connected to a positioning plate 50 2. A mounting cylinder 504 is fixedly connected to one side of the support frame 2, a driving motor 503 is installed outside the mounting cylinder 504, a driving shaft 512 is fixedly connected to the output end of the driving motor 503, a plurality of dividing plates 513 are fixedly connected to the outer surface of the driving shaft 512, a first feeding port 505 is opened on one side of the outer surface of the mounting cylinder 504, a second feeding port 511 is opened on the other side of the outer surface of the mounting cylinder 504, a placing plate 514 is fixedly installed on the inner side of the body 1, and a discharge plate 515 is fixedly connected to the output end of the second feeding port 511.

[0048] Specifically, expand in sections.

[0049] The driving assembly includes two first electric guide rails 401, both of which are fixedly mounted on the inner wall of the body 1, a first electric slider 402 is installed outside the first electric guide rails 401, a second electric guide rail 403 is installed between the two first electric sliders 402, and a second electric slider 404 is installed outside the second electric guide rail 403.

[0050] Specifically, the first electric guide rail 401 provides a smooth linear motion track, so that the first electric slider 402 can slide freely thereon, thereby achieving efficient positioning and movement. The second electric guide rail 403 installed between the two first electric sliders 402 further enhances the flexibility of the structure, allowing the second electric slider 404 to be accurately adjusted at different positions.

[0051] A connecting frame 405 is welded on the top of the second electric slider 404. Two cylinders 406 are fixedly connected to the outer surface of the connecting frame 405. The output ends of the two cylinders 406 are respectively fixedly connected to a laser cutting gun 407 and a laser welding gun 408.

[0052] Specifically, both the laser cutting gun 407 and the laser welding gun 408 are equipped with a high-power laser source, specifically a fiber laser or a carbon dioxide laser, and a suitable wavelength and power are selected according to the requirements of cutting and welding. The laser cutting gun 407 and the laser welding gun 408 are internally provided with a precise optical path system, including a lens and a reflector, for focusing the laser beam. The system is an existing mature technology product, which is well known to those skilled in the art, and therefore will not be repeated here.

[0053] The fixed component includes a two-way guide rail, which is fixedly installed on the inner side of the body 1. Two mounting plates 301 are installed on the top of the two-way guide rail. The outside of the mounting plate 301 is fixedly connected to an electric telescopic rod 305, and the output end of the electric telescopic rod 305 is fixedly connected to a driving block 306. The outside of the mounting plate 301 is movably connected to a mounting disk 307 through a bearing, and the inside of the mounting disk 307 is rotatably connected to a plurality of swing rods 308. The inner side wall of the mounting plate 301 is provided with a plurality of limit grooves 302, and the inside of the limit grooves 302 is slidably connected to a movable block 304, and the outside of the movable block 304 is fixedly connected to a clamping plate 303.

[0054] Specifically, by starting the electric telescopic rod 305, the electric telescopic rod 305 drives the driving block 306 to move, so that the mounting plate 307 rotates, and at this time, one end of the swing rod 308 located on the outer surface of the mounting plate 307 swings, and under the traction of the swing rod 308, the movable block 304 is driven to move along the inner wall of the limit groove 302, so that multiple movable blocks 304 are driven to move synchronously. Until the inner wall of the clamping plate 303 contacts the outer surface of the workpiece, the clamping function is realized, and the precision in the cutting or welding process can be ensured through stable clamping, and the risk of deformation or dislocation of the workpiece can be reduced, thereby improving product quality.

[0055] The number of the plurality of movable blocks 304 corresponds to the number of the clamping plates 303 , and the plurality of movable blocks 304 are respectively connected to the outer portion of the swing rod 308 at the corresponding position for rotation.

[0056] Specifically, the number of the plurality of movable blocks 304 corresponds to the number of the clamping plates 303. This one-to-one design ensures that each clamping plate 303 can effectively control the corresponding workpiece. The movable blocks 304 are connected to the external rotation of the swing rod 308 to achieve precise operation of the clamping plates 303. Specifically, when the swing rod 308 rotates, it will be directly transmitted to the corresponding movable blocks 304, so that the clamping plates 303 can achieve the required clamping or releasing action. This design not only improves the stability and accuracy of clamping, but also can complete the rapid replacement of multiple workpieces in a short time, significantly improving production efficiency.

[0057] The cross section of the mounting block 507 is set to be square, and the outside of the mounting block 507 is slidably connected to the inner wall of the slide groove 501, which can ensure that the mounting block 507 can move along the inner wall of the slide groove 501.

[0058] The plurality of limiting grooves 302 are centrally symmetrically arranged along the perpendicular midline of the mounting plate 301 , and the outer surface of the clamping plate 303 is arranged as an arc surface.

[0059] Specifically, the central symmetric arrangement ensures that the force distribution of the clamping plate 303 is more uniform when clamping the workpiece, reducing the deformation or loosening of the workpiece due to uneven force. In addition, the design of the limit groove 302 can also effectively prevent the clamping plate 303 from shifting during the working process, thereby maintaining the accuracy of the clamping position and ensuring the consistency of each processing.

[0060] The outer surface of the dividing plate 513 is slidably connected to the inner wall of the mounting tube 504 , and the driving block 306 is rotatably connected to the outer side of the mounting disk 307 .

[0061] In the fully automatic laser cutting and welding equipment, the outer surface of the material dividing plate 513 is slidably connected to the inner wall of the mounting cylinder 504. This design ensures that the material can move smoothly during the transmission process, reduces friction and wear, and improves the overall stability of the system. The driving block 306 is connected to the outer side of the mounting plate 307 by rotation, so that the driving block 306 can flexibly adjust its position.

[0062] A rubber pad is provided on the inner side of the positioning plate 502 , and the lower surface of the positioning plate 502 is in contact with the upper surface of the support frame 2 .

[0063] Specifically, the inner side of the positioning plate 502 is equipped with a rubber pad. This innovative design not only enhances the stability of positioning and reduces the impact of vibration on processing accuracy, but also protects the surface of the workpiece to avoid scratches or damage during processing. The lower surface of the positioning plate 502 fits tightly with the upper surface of the support frame 2, making the entire structure more solid and providing a reliable foundation for laser cutting and welding. This multiple design optimization improves the reliability and processing efficiency of the equipment, laying a solid foundation for achieving efficient automated production.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
