By controlling the cutting angle and depth, the groove cutting can meet different process requirements and is suitable for scenes requiring groove processing such as pipelines and welding joints. At the same time, this auxiliary bed lifting structure can ensure that the movable bed entering the main bed is at the same height in the hollow bed every time. Such a structure breaks the traditional design of replacing the bed by stacking up and down. Such a design can shorten the stroke of the laser cutting head each time it goes down to cut the plate, avoid the problem of the laser cutting head shaking due to excessive stroke in the Z direction, and greatly improve the stability and precision of laser cutting. At the same time, this structure further improves the overall height of the plate cutting bed. When the laser cutting head moves horizontally to the two sides for cutting, due to the small downward stroke, the swing angle of the laser head will be larger, and it will not interfere with the two side beams of the hollow bed, which can increase the cutting angle and improve the cutting flexibility; the beam device 31 includes a beam body 311, a second rack 312 is fixedly connected to one side of the upper end of the beam body 311, an upper end slide rail 313 is fixedly connected to one side adjacent to the second rack 312, and a side end slide rail 314 is fixedly connected to one side of the lower end of the beam body 311. The existence of the upper end slide rail and the side end slide rail helps to provide a guiding effect, ensuring that the device can move smoothly during operation, reducing swinging or irregular movement, thereby improving precision and stability;The lateral movement mechanism 32 includes a T-shaped back plate 321, a third rotating motor 322 is fixedly connected to one side end of the T-shaped back plate 321, a second rotating gear 323 is provided at the output end of the third rotating motor 322, a fourth rotating motor 324 is provided at the adjacent end of the third rotating motor 322, a third rotating gear 325 is provided at the output end of the fourth rotating motor 324, an upper end slider 326 is fixedly connected to the back of the lower end of the T-shaped back plate 321, a side end slider 327 is fixedly connected to one side of the lower end of the T-shaped back plate 321, both ends of one side of the T-shaped back plate 321 are fixedly connected to second slide rails 328, a plurality of second slide rails 329 are slidably connected to the second slide rails 328, and the upper end slider 326 is fixedly connected to the back of the lower end of the T-shaped back plate 321. 26 is assembled and connected with the upper end slide rail 313, the side end slider 327 is assembled and connected with the side end slide rail 314, and the second rotating gear 323 is assembled and connected with the second rack 312. Through the multi-point support of the T-shaped back plate, the slide rail and the slider, the overall motion trajectory is more stable, reducing the error caused by structural deviation. The precise matching of the slide rail and the slider effectively reduces the vibration and friction during the movement, improves the accuracy of the movement, and is particularly suitable for high-precision cutting, positioning and processing work; the Z-direction moving mechanism 33 includes a second fixed plate 331, and an anti-collision block 332 is arranged at one end of the second fixed plate 331, and sliders are arranged at both ends of one side of the second fixed plate 331. The fixing groove 333, the adjacent end of the slider fixing groove 333 is provided with a third rack 334, the third rack 334 is assembled and connected with the third rotating gear 325, the slider fixing groove 333 is fixedly connected with the second slider 329, and the Z-direction moving mechanism realizes high-precision and stable Z-direction movement through the coordinated action of key components such as the second fixing plate, the anti-collision block, the slider fixing groove, the third rack and the second slider; the groove swing axis cutting mechanism 38 includes a fixing frame 381, and a first swing motor reducer 382 is provided on one end of the fixing frame 381, and a U-shaped rotating shaft 383 is connected to the output end of the first swing motor reducer 382, ​​and a fixed connection is provided on one side of the U-shaped rotating shaft 383 It is connected to the second swing motor reducer 384, and the output end of the second swing motor reducer 384 is fixedly connected to the laser cutting head 385. Through the cooperation of the first swing motor reducer and the second swing motor reducer, combined with the U-shaped rotating shaft, precise angle adjustment can be achieved, so that the laser cutting head can flexibly swing in multiple directions, thereby ensuring high precision and high quality during the groove cutting process. The use of the swing motor reducer can effectively reduce the change in cutting accuracy caused by the fluctuation of the power system. Through the fine control of the reducer, the laser cutting head can run stably at the required angle and speed, avoiding cutting errors caused by system instability. ;

[0019] During operation, the main structure of the lifting bed 11 is driven to lift by the servo electric cylinder 1132. The fixed feet 1131 and the protective cover 1134 ensure the stability of the equipment during the lifting process. The servo electric cylinder 1132 provides high-precision and high-efficiency power output to ensure the long-term stable operation of the lifting system. The guide rail system of the bed can be assembled with the lower bed guide rail 114 or the upper bed guide rail 115 through the lifting mechanism 113. The mobile bed transposition traction mechanism 222 is connected to the upper bed. The upper movable bed 13 and the lower movable bed 12 can be dragged to the hollow bed 2 by the traction chain 2225 through the positioning pin 2221 of the upper bed and the traction pin 2222 of the lower bed to ensure accurate docking after the bed is lifted and lowered. The upper movable bed 13 and the lower movable bed 12 can be dragged to the hollow bed 2 by the traction chain 2225 through the positioning traction member 2226 on the rotating sprocket 2224. The upper movable bed 13 and the lower movable bed 12 can be dragged to the hollow bed 2. This device ensures that each bed is on the same horizontal line when entering the hollow bed 2, and shortens the distance with the laser cutting head, ensuring that the laser head will not be affected by the travel of the line during each downward cutting stroke. The large range causes the laser cutting head to shake, resulting in affected accuracy. The laser cutting device is located on the hollow bed 2, and realizes complex spatial movement through the beam device 31, the lateral moving mechanism 32 and the Z-direction moving mechanism 33. Limited position fixing seats 34 are arranged on both sides of the beam device, which are connected to the first rack 215 through the first rotating gear 36 to drive the beam to move along the X-axis. The Z-direction moving mechanism 33 is connected to the third rotating gear 325 through the second fixed plate 331 and the third rack 334 to realize the fine lifting and lowering of the laser cutting head and ensure the precise focusing of the laser beam. The groove swing axis cutting mechanism 38 is controlled by a motor so that the laser cutting head can swing during the cutting process to meet the cutting requirements of different groove angles. The laser cutting head 385 is driven by the first and second swing motors, and works in coordination with the second swing motor reducer 384 through the U-shaped rotating shaft 383, and can change the cutting angle and position as needed. Through this process, the laser head can accurately cut on the surface of the material with high cutting accuracy and smooth edges.
