Description

Technical Field

[0001] The invention relates to the technical field of laser welding and cutting, in particular to a three-dimensional multi-axis laser cutting and welding device. Background Art

[0002] The laser cutting device is mainly composed of a laser generator, an optical path system, a control system, a motion system, and an auxiliary gas system. The inclination angle of the existing laser welding and cutting device is often difficult to adjust, and it is troublesome to cut materials of different shapes. It requires manual assistance in cutting, which is time-consuming and labor-intensive. It is not suitable for cutting materials of different shapes, which greatly affects the cutting efficiency of the laser welding and cutting device and has poor practicality.

[0003] The Chinese patent with the announcement number "CN216966658U" discloses a laser welding and cutting device with multi-angle adjustment, including a cutting machine body, a cutting device, a first movable rod, a second movable rod and a limit adjustment mechanism. The above device adjusts the angle of the cutting device by setting a limit adjustment mechanism. When cutting materials of different shapes, the screw cap of the limit adjustment mechanism rotates to drive the threaded vertical rod, the threaded vertical rod drives the rotating horizontal axis to rotate, and the rotating horizontal axis drives the cutting device to rotate at a certain angle to adapt to the cutting of materials of different shapes;

[0004] Although the above-mentioned device can assist in adjusting the angle, in actual application, it can only simply adjust the angle in one direction. In the actual processing process, the processing parts usually faced are extremely complex. If the parts need to be cut or welded in another direction, it is obviously impossible to achieve three-dimensional adjustment. In addition, there are obvious differences between laser welding heads and laser cutting heads. First of all, laser welding requires the material to be locally heated to the melting point and fused, so the requirements for the energy distribution and power density of the light spot are very different from those of laser cutting. Welding usually requires a wider and more uniform energy distribution to form a good weld, while laser cutting uses a high-energy-density concentrated light spot to quickly melt and vaporize the material, thereby achieving material separation. Cutting requires a high concentration of light spot energy to achieve the purpose of quickly and accurately cutting the material. It can be seen that laser welding and laser cutting cannot share a laser head. Therefore, the above-mentioned equipment cannot perform laser welding or laser cutting according to actual needs. It obviously has certain defects and deficiencies, so it needs to be improved. Summary of the invention

[0037] The working principle of the present invention is as follows: by setting the rotation displacement mechanism 2 and the linear displacement mechanism 3 to cooperate with each other, the present device can be operated by starting the third motor 332 during use. When the third motor 332 is running, it will drive the one-way screw rod 333 to rotate. With the help of the rotation of the one-way screw rod 333, the sliding sleeve 334 can be assisted in sliding and displacing on one side of the top frame 32. As the sliding sleeve 334 slides, the movable frame 41 will be driven to slide and displace horizontally. The sliding displacement of the movable frame 41 can further assist in driving the welding and cutting mechanism 4 to move horizontally. At this time, if the fourth motor 23 is started, the fourth The motor 23 drives the transmission gear 24 to rotate the gear ring 22, and the rotation of the gear ring 22 can drive the support rod 31 to rotate. In this way, not only the lateral displacement direction of the linear displacement mechanism 3 can be changed, but also the rotary displacement mechanism 2 and the linear displacement mechanism 3 cooperate with each other, and the welding and cutting mechanism 4 can be adjusted and rotated during use, and its linear displacement can be further adjusted on the basis of rotation. In this way, the device located at the top of the clamping mechanism 5 can be flexibly adjusted, and the whole can adapt to the welding process in any direction of the top of the clamping mechanism 5, and the adaptability of the overall welding process is significantly enhanced;

[0038] By setting up the clamping mechanism 5, the device can place the product to be processed on the inner side of the clamping frame 524 during use. Since the clamping frame 524 is L-shaped, the product to be processed can be stably clamped and installed inside the clamping frame 524. At this time, the top of the ball 527 is in close contact with the bottom of the product, and the inner side of the conveying crawler 525 is in close contact with both sides of the product. During this period, by starting the fifth motor 53, the fifth motor 53 can drive the driving gear 54 to rotate. Since the driving gear 54 and the driven gear 55 are meshed and connected, as the fifth motor 53 drives the driving gear 54 to rotate, the driving gear 54 can then drive the driven gear 55 to rotate. The rotation of the driven gear 55 can drive the bidirectional screw rod 522 inside the guide rail 521 to rotate, and the rotation of the bidirectional screw rod 522 can The guide rail 521 is provided with a plurality of support members 524, each of which is provided with a plurality of support members 526, and each of which is provided with a plurality of support members 527.

[0039] By setting the welding and cutting mechanism 4, the device can flexibly adjust the position of the welding and cutting mechanism 4 by starting the rotation displacement mechanism 2 and the linear displacement mechanism 3 during use, so that the device as a whole can flexibly adjust the position and direction required for welding. After the adjustment is completed, the first motor 42 can be started to drive the first cylinder 43 to rotate. At this time, the angle of the overall welding processing of the device can be further adjusted. By starting the first cylinder 43, the first cylinder 43 can drive the welding and cutting assembly 44 to approach the product to be processed. At this time, the conveying crawler 525 drives the product to move. The rotation displacement mechanism 2 and the linear displacement mechanism 3 can drive the welding and cutting mechanism 4 to move, so that the device as a whole can flexibly perform linear cutting or rotation cutting. During the processing, if it is necessary to change the cutting to welding, it is only necessary to start the second cylinder 443. The second cylinder 443 drives the sliding frame 444 to slide on the inner side of the rail frame 442. The displacement of the sliding frame 444 can drive the sliding hole 445 and the sliding rod 446 inside it to move horizontally. Due to the guide assembly 449 The setting is that during the lateral displacement of the sliding frame 444, the slider 4492 slides along the guide frame 4491. The slider 4492 can be guided by the guide frame 4491, which can cause the sliding frame 444 to slide up and down inside the sliding hole 445. The guide frame 4491 is set in a V shape. When the laser cutting head 448 is located in the middle of the guide frame 4491, the laser cutting head 448 is located at the bottom. It can be driven by the second cylinder 443 to push the laser cutting head 448 to move. At this time, laser welding The head 447 is guided by the guide frame 4491 and moves to the bottom. At this time, the laser welding head 447 can be adjusted to move to the bottom in the middle, so that during use, the position of the laser cutting head 448 and the laser welding head 447 can be flexibly adjusted. The sliding hole 445 and the sliding rod 446 can assist in reinforcing the guide, so that the position of the laser welding head 447 and the laser cutting head 448 can be flexibly adjusted, so that the entire device can perform laser welding processing or laser cutting processing, which can further improve the overall adaptability of the equipment.
