A collecting ring 18 is threadedly mounted on the lower end of the protective cover 16. When the flange is laser processed, debris will be generated. When the debris is sputtered, it will slide along the inner wall of the collecting ring 18 into the cavity of the protective cover 16, and then fall along the cavity of the protective cover 16 into the collecting ring 18 to be collected. This device can effectively collect the debris and prevent it from splashing around in the processing space, thereby keeping the processing environment clean and orderly, and facilitating processing operations and equipment maintenance for operators.

One end of the two groups of first springs 33 away from the first slide 32 is fixedly connected to the two fixed seats 26 respectively. A clamp 34 is fixedly mounted on the opposite end of the two groups of first slides 32. A wedge block 35 is fixedly mounted on the opposite end of the two clamps 34. A loading plate 36 is fixedly mounted on the opposite end of the two fixed seats 26. The two loading plates 36 are cross-distributed. An adjustment block 41 is provided between the two fixed seats 26 and the slide bar 22. An inner column 42 is fixedly mounted on both side walls of the two adjustment blocks 41. The two groups of inner columns 42 are slidably mounted in the two groups of inner grooves 29 respectively. A threaded groove 43 is provided on the opposite end of the two adjustment blocks 41. The lower ends of the two threaded grooves 43 The two adjusting blocks 41 are provided with a second circular groove 44, the lower ends of the two adjusting blocks 41 are provided with a second limiting groove 45, the two threaded grooves 43 are threadedly installed with a first screw 46, the lower ends of the two first screws 46 are fixedly installed with a limiting disk 47, and the two limiting disks 47 are rotatably installed in the two second limiting grooves 45 and the two first limiting grooves 28 respectively. When the flange is fixed, the gantry 12, the galvanometer 13 and the laser head 14 can be controlled by the control panel 15 to process the flange. When the flange produces a slight deformation during laser processing, the originally set processing position will deviate from the expected deflection. At this time, the two slide bars 22 can be slid on the fixing frame 21. After the adjustment is completed, the two sets of positioning rings 19 can be rotated on the fixing frame 21 to complete the fixation of the two slide bars 22, and the first The screw 46 rotates the lower limit plate 47 of the first screw 46 and rotates inside the second limit groove 45 and the first limit groove 28. Since the adjusting block 41 is threadedly connected to it, the adjusting block 41 will slide toward the fixed seat 26, and the two inner columns 42 slide inside the two inner grooves 29 respectively. At this time, the adjusting block 41 will be separated from the slide bar 22. At this time, the dovetail block 24 can be slid inside the two dovetail grooves 23. At this time, the dovetail block 24 will drive the connecting bar 25 and the fixed seat 26 to move accordingly. When it is adjusted to the appropriate position, the first screw 46 can be rotated counterclockwise. Similarly, the adjusting block 41 will slide toward the slide bar 22. When the adjusting block 41 contacts the slide bar 22, the fixation is completed. This equipment allows operators to quickly adjust the flange position at any time according to processing requirements.The laser beam is precisely aligned with each processing part to ensure processing accuracy and quality, significantly improving processing efficiency. In addition, this method allows for fine-tuning of the processing position without disassembling the flange, avoiding the accumulation of position deviations caused by repeated assembly and disassembly, reducing unnecessary operations on the flange, saving adjustment time, and lowering the risks caused by disassembly, thereby ensuring the stability of the flange during processing and helping to improve the product qualification rate. The two side blocks 51 are fixedly installed on the opposite ends of the two fixing seats 26, and the two side blocks 51 are provided with second sliding grooves 52. Wedge bars 53 are slidably installed inside the two second sliding grooves 52. Second springs 54 are symmetrically fixedly installed on the two wedge bars 53. The two second springs 54 are fixedly connected to the two side blocks 51 at one end away from the two wedge bars 53. Second screws 55 are threadedly installed on the two side blocks 51. When in use, the flange to be processed can be placed on the two loading plates 36 first, and then the two second screws 55 can be rotated on the two side blocks 51. The rotation of the two second screws 55 will squeeze the wedge bars 53 downward. After the two wedge bars 53 are subjected to force, they will move downward inside the two second sliding grooves 52. At this time, the two wedge bars 53 will squeeze the two wedge blocks 35, and the two The wedge blocks 35 will be forced to move toward the middle, which will drive the two clamps 34 to slide toward the middle. The two clamps 34 will drive the two groups of first slides 32 to slide in the two groups of first slide grooves 31 during the movement. At this time, the two groups of first springs 33 will be compressed. At this time, the two clamps 34 will fix the flange to avoid flange displacement due to vibration, external force and other factors during the processing process, providing a reliable foundation for subsequent laser cutting, welding and other processing procedures, ensuring processing accuracy and quality. By designing the two clamps 34 into a V shape, it is suitable for fixing flanges of any specifications, which greatly expands the applicability of the processing operating table to the flange, reduces the time and cost of replacing clamps or adjusting equipment due to differences in flange specifications, and improves the versatility and production efficiency of the equipment.
[0020] Working principle: In the first step, when using, the flange to be processed can be placed on the two loading plates 36, and then the two second screws 55 can be rotated on the two side blocks 51. Under the rotation of the two second screws 55, the wedge bars 53 will be squeezed downward. After the two wedge bars 53 are subjected to force, they will move downward inside the two second chutes 52. At this time, the two wedge bars 53 will squeeze the two wedge blocks 35. The two wedge blocks 35 will be forced to move toward the middle, and then the two clamps 34 will slide toward the middle. The two clamps 34 will drive the two sets of first slides 32 in the two sets of first slides 31 during the movement. Sliding, the two sets of first springs 33 will be compressed, and the two clamps 34 will fix the flange to prevent the flange from shifting due to vibration, external force and other factors during the processing, providing a reliable foundation for subsequent laser cutting, welding and other processing procedures, ensuring processing accuracy and quality. By designing the two clamps 34 into a V shape, they are suitable for fixing flanges of any specifications, greatly expanding the applicable range of the processing operation table for flanges, reducing the time and cost of replacing clamps or adjusting equipment due to differences in flange specifications, and improving the versatility and production efficiency of the equipment; In the second step, after the flange is fixed, the gantry 12, the galvanometer 13 and the laser head 14 can be controlled through the control panel 15 to process the flange. When the flange produces a slight deformation during laser processing, the originally set processing position will deviate from the expected one. At this time, the two slide bars 22 can be slid on the fixed frame 21. After the adjustment is completed, the two sets of positioning rings 19 can be rotated on the fixed frame 21 to complete the fixation of the two slide bars 22. The first screw 46 can also be rotated clockwise. When the first screw 46 is rotated, the lower limit plate 47 will rotate inside the second limit groove 45 and the first limit groove 28. Since the adjustment block 41 is threadedly connected to it, the adjustment block 41 will slide toward the direction of the fixed seat 26, and the two inner columns 42 will slide inside the two inner grooves 29 respectively. At this time, the adjustment block 41 will be separated from the slide bar 22 and can slide inside the two dovetail grooves 23 Dovetail block 24, at this time the dovetail block 24 will drive the connecting bar 25 and the fixing seat 26 to move accordingly. When it is adjusted to the appropriate position, the first screw 46 can be rotated counterclockwise. Similarly, the adjusting block 41 will slide toward the slide bar 22. When the adjusting block 41 contacts the slide bar 22, the fixation is completed. This equipment allows the operator to quickly adjust the flange position at any time according to the processing requirements, so that the laser beam is accurately aimed at each processing part, ensuring the processing accuracy and quality, and significantly improving the processing efficiency. In addition, in this way, the processing position can be fine-tuned without disassembling the flange, avoiding the accumulation of position deviations caused by repeated loading and unloading, reducing unnecessary operations on the flange, saving adjustment time, and reducing the risks caused by disassembly, thereby ensuring the stability of the flange during the processing and helping to improve the qualified rate of the product. In the third step, since the laser head 14 will maintain a close fit with the flange during processing, the protective cover 16 will also be adjusted with the laser head 14 during operation. During the entire processing process, the protective cover 16 will protect the laser head 14 to prevent the laser head 14 from colliding during the processing. When the protective cover 16 moves with the laser head 14, the two distance sensors 17 will also move accordingly. When the two distance sensors 17 move to a position where they will contact an obstacle, an alarm will be issued, further improving the safety of the laser head 14 during use. This equipment can reduce the probability of damage to the laser head 14, reduce the number of maintenance times and maintenance costs, and shorten the equipment downtime due to maintenance, thereby improving production efficiency and ensuring the continuity and stability of flange processing. In the fourth step, debris will be generated during the laser processing of the flange. When the debris is sputtered, it will slide along the inner wall of the collection ring 18 into the cavity of the protective cover 16, and then fall along the cavity of the protective cover 16 to be collected inside the collection ring 18. This equipment can effectively collect the debris and prevent it from splashing around in the processing space, keeping the processing environment clean and orderly, and facilitating the operator to perform processing operations and equipment maintenance.
