The inner sides of the two component guide plates 31 are both beveled, and the tops of the inner sides of the left and right sets of expansion rods 33 are fixedly connected with columnar cross-link rods 35. The inner ends of the left and right sets of columnar cross-link rods 35 are fixedly connected to the front and rear sides of the outer sides of the two expansion plates 2115. The tops of the two component guide plates 31 are both provided with bottom limit control components 36, and the two bottom limit control components 36 each include two stop blocks 361. The outer sides of the two sets of stop blocks 361 are both the outer tops of the two component guide plates 31. The opposite beveled surfaces are both in contact with the outer tops of the two component guide plates 31. The tops of the left and right sets of stop blocks 361 are fixedly connected to columnar bottom limit plate push rods 362. The tops of the left and right sets of columnar bottom limit plate push rods 362 extend through the four through slots 216 defined in the bottom plate 215 to the top of the bottom plate 215 and are fixedly connected to C-shaped bottom limit plates 363. The outer walls of the left and right sets of columnar bottom limit plate push rods 362 are both sleeved with springs 364 on one side of the bottom of the bottom plate 215. When performing the laser cutting operation on steel, the first step is to place the steel to be cut on the upper surface of the two C-shaped bottom limit plates 363. Then, the operator will start the two-way hydraulic push rod 2113 located on the inner wall of the front side of the inverted L-shaped hydraulic push rod connecting plate 2112. When the two-way hydraulic push rod 2113 is activated, its left and right ends will synchronously push the two L-shaped horizontal push plates 2114 to move to both sides. As the L-shaped horizontal push plates 2114 move, they will drive the expansion plates 2115 and the U-shaped expansion plates 2116 to slide in the guide top plate groove 2110 of the guide top plate 219 and gradually expand to both sides. In this process, the columnar horizontal push rod 2117 and the hinged push block 2118 will also move accordingly, and then through the transmission action of the V-shaped rotating short rod 221, the T-shaped pressure block 222 and the columnar pressure rod 223 will move downward, and finally be pressed down by the lower pressure plate 224 and tightly attached to both sides of the steel. At the same time, as the expansion plate 2115 moves outward, they will also drive the component guide plate 31 and the expansion vertical rod 33 to move outward through the columnar cross tie rod 35, so that the expansion vertical rod slider 34 will slide in the cross bar guide groove 213. Since the outer top and inner side of the component guide plate 31 are both beveled surfaces, as the component guide plate 31 moves outward, its beveled surface will contact the two sets of stop blocks 361 and push them to move upward. Subsequently, through the action of the two sets of columnar bottom limit plate push rods 362, the two sets of C-shaped bottom limit plates 363 are pushed to move toward the top. In this way, through the clamping of the two lower pressure plates 224 and the two bottom limit control assemblies 36 The four sides of the steel are firmly fixed. Next, the laser cutting head control board 2120 will start, driving the laser cutting head 2121 to descend and start precise laser cutting of the steel. The moving path of the laser cutting head 2121 can be controlled by a preset program to ensure the accuracy and efficiency of the cutting. As the two component guide plates 31 move outward, gaps will be exposed on their inner sides. The cut components will slide to the top of the conveyor table 1 through the guiding effect of the inner beveled surfaces of the two component guide plates 31. Finally, the two conveyor tables 1 will convey the cut components to the designated position, completing the entire laser cutting process.

[0022] Working principle of the present invention: In the initial stage of the steel laser cutting operation, the steel to be cut is placed on the upper surface of the two C-shaped bottom limit plates 363. Then, the operator will start the bidirectional hydraulic push rod 2113 located on the inner wall of the front side of the inverted L-shaped hydraulic push rod connecting plate 2112. Once the bidirectional hydraulic push rod 2113 is activated, its left and right ends will synchronously push the two L-shaped horizontal push plates 2114 to move to both sides. As the L-shaped horizontal push plates 2114 move, they will drive the expansion plate 2115 and the U-shaped expansion plate 2116 to move in the guide top plate groove 2119 of the guide top plate 219. 10 and gradually expand to both sides. In this process, the columnar horizontal push rod 2117 and the hinged push block 2118 will also move accordingly, and then through the transmission action of the V-shaped rotating short rod 221, the T-shaped pressure block 222 and the columnar pressure rod 223 will move downward, and finally press down and cling to both sides of the steel through the lower pressure plate 224. At the same time, as the expansion plate 2115 moves outward, they will also drive the component guide plate 31 and the expansion rod 33 to move outward through the columnar horizontal tie rod 35. In this way, the expansion rod slider 34 will be in the horizontal The rod slides in the guide groove 213. Since the outer top and inner side of the component guide plate 31 are beveled surfaces, as the component guide plate 31 moves outward, its beveled surfaces will contact the two sets of stop blocks 361 and push them upward. Subsequently, the two sets of columnar bottom limit plate push rods 362 push the two sets of C-shaped bottom limit plates 363 to move toward the top. In this way, the four sides of the steel are firmly fixed by the clamping of the two lower pressure plates 224 and the two bottom limit control assemblies 36. Next, the laser cutting head control board 2120 will be started. The laser cutting head 2121 is driven down to start precise laser cutting of the steel. The moving path of the laser cutting head 2121 can be controlled by a preset program to ensure the accuracy and efficiency of the cutting. As the two component guide plates 31 move outward, gaps will be exposed on their inner sides. The cut components will slide to the top of the conveyor table 1 through the guidance of the inner beveled surfaces of the two component guide plates 31. Finally, the two conveyor tables 1 will convey the cut components to the designated position, completing the entire laser cutting process.
