An air pipe 16 is fixedly installed at the bottom of the first cold air box 15, and a control valve is fixedly installed at one end of the air pipe 16. A cavity is provided at the top of the connecting block 13, and one end of the air pipe 16 is located inside the cavity. A through hole is provided on the outer wall of the connecting block 13, and a second annular groove is provided at the bottom of the connecting block 13 and located at the bottom of the cavity. An electric telescopic protective plate 19 is fixedly installed inside the second annular groove, and one end of the electric telescopic protective plate 19 passes through the second annular groove and extends to the bottom of the connecting block 13. The probe 14 is located in the middle of the telescopic end of the electric telescopic protective plate 19, and the support blocks 12 are located on both sides of the connecting block 13, and they are located above the probe 14.

[0029] Move the box door upwards to fix the aluminum profile inside the placement slot, and use the control device 2 to make the movable structure 3 drive the laser hole opening machine 6 to move to the position where the hole needs to be opened, and then use the sliding block 4 to adjust the mounting block 5, the laser hole opening machine 6, and the laser head 7, so that the laser head 7 is aligned with the position where the hole needs to be opened on the aluminum profile, and the laser hole opening machine 6 and the laser head 7 open the hole. When the hole opening is completed, the laser head 7 is separated from the aluminum profile, and the first electric push rod 8 is started to drive the fixing block 9, the first fixing rod 10 and the connecting block 13 to move downward, so that the mounting plate 11 drives the support block 12 to move downward, and the position of the support block 12 is adjusted according to the size of the hole through the adjustment structure inside the mounting plate 11.

[0031] The protective plate 17 is installed through the first annular groove. When the first electric push rod 8 is started to drive the fixed block 9 to move downward, the fixed block 9 drives the connecting plate 18 to move downward along the slide groove, so that the protective plate 17 moves out of the first annular groove and moves to the outside of the laser head 7 to protect the laser head 7 from collision and damage, which affects its use.

[0032] like Figures 6 to 9As shown, the adjustment structure includes two second electric push rods 20, a moving plate 21 is fixedly installed on one side of the two second electric push rods 20, a movable block 22 is fixedly installed on one side of the moving plate 21, a moving block 23 is fixedly installed on the bottom of the movable block 22, the bottom of the moving block 23 is fixedly installed with the top of the support block 12, a first moving groove is opened inside the mounting plate 11, the moving plate 21 and the movable block 22 are both slidably connected to the inner wall of the first moving groove, fixed plates are fixedly installed inside the first moving groove and on both sides of the first electric push rod 8, one side of the two second electric push rods 20 is fixedly installed with the fixed plate, a moving opening is opened at the bottom of the mounting plate 11 away from the first electric push rod 8, the moving block 23 is located inside the moving opening, and the support block 12 is located at the bottom of the moving opening.

[0033] Two second electric push rods 20 are installed through the fixed plate, and the two second electric push rods 20 are started, so that the moving plate 21 drives the movable block 22 to move along the inner wall of the first moving groove, thereby improving the stability of the moving plate 21 and the movable block 22 when moving, and the moving opening facilitates the moving block 23 to drive the support block 12 to move when it moves, so that the support block 12 moves away from the first fixed rod 10, so that the support block 12 can be adjusted according to the size of the hole, so that when the probe 14 is moved to the inside of the hole for detection, the support block 12 can be supported on the top of the aluminum profile, thereby improving the stability of the probe 14 and improving the detection effect.

[0034] like Figures 7 to 9 As shown, the mounting plate 11 is located at the connecting end of the first fixed rod 10 and the connecting block 13, and the second fixed rods 24 are fixedly installed at both ends of the top of the mounting plate 11. The top of the second fixed rod 24 is fixedly installed with the bottom of the fixed block 9, and the two second electric push rods 20, the moving block 23, the movable block 22, the moving block 23 and the supporting block 12 are all symmetrically arranged with respect to the center of the mounting plate 11.

[0035] The mounting plate 11 is used to facilitate connection with the support block 12, and the second fixing rod 24 is used to facilitate improvement of the stability of the mounting plate 11 on the outside of the first fixing rod 10 and the connecting block 13, thereby facilitating movement and adjustment of the support block 12. The symmetrically arranged second electric push rod 20 drives the movement of the moving plate 21, the movable block 22, the moving block 23 and the support block 12, thereby further improving the detection effect of the probe 14.

[0036] like Figure 5 , Fig.10 As shown, a first protective block 25 is fixedly installed at the bottom of the mounting block 5 and at the bottom of the mounting groove. The first protective blocks 25 are located at both ends of the bottom of the mounting block 5. A movable groove is opened at the top of the first protective block 25. An electric telescopic rod 26 is fixedly installed on the inner wall of the movable groove. A second protective block 27 is fixedly installed at one end of the electric telescopic rod 26. The top of the second protective block 27 is slidably connected to the bottom of the mounting block 5. The second protective block 27 is located between the two first protective blocks 25, and one side thereof is in contact with each other.

[0037] The first protective block 25 and the second protective block 27 are used to shield and protect the bottom of the mounting block 5, so that the mounting groove remains sealed to prevent the probe 14 inside the mounting groove from being damaged. The electric telescopic rod 26 is started to drive the second protective block 27 to move along the bottom of the mounting block 5, so that the two second protective blocks 27 move away from each other and no longer fit together. When the electric telescopic rod 26 is contracted to move the second protective block 27 to the inside of the movable groove, the middle position of the bottom of the mounting block 5 is exposed, thereby facilitating the movement of the probe 14 for detection and facilitating use.

[0038] like Figure 5 , Fig.10 As shown, a first support plate is fixedly installed on the top of the first protective block 25 and on the inner wall of the mounting groove, a first motor 28 is fixedly installed inside the first support plate, a threaded rod 29 is transmission-connected to the output end of the first motor 28, a second support plate is rotatably connected to the top of the threaded rod 29, a movable plate 30 is threadedly connected to one end of the threaded rod 29, one side of the movable plate 30 is slidably connected to the inner wall of the mounting groove, a second cold air box 31 is fixedly installed on the top of the movable plate 30, a cold air pipe is fixedly installed on one side of the second cold air box 31, a solenoid valve is provided at one end of the cold air pipe, and a nozzle 32 is provided at the other end thereof.

[0039] When the laser drilling machine 6 and the laser head 7 are drilling a hole, heat is generated, and then the first motor 28 is started to drive the threaded rod 29 to rotate along the top of the second support plate, so that one side of the movable block 22 moves along the inner wall of the installation groove and moves up and down along the threaded rod 29, and then the solenoid valve is started to spray the cold air inside the second cold air box 31 through the cold air pipe from the nozzle 32, so that the temperature inside the installation groove is reduced, preventing the temperature inside the installation groove from being too high and affecting the service life of the probe 14, which is not conducive to improving the detection accuracy and effect.

[0040] like Figures 6 to 8 As shown, a sealing plate 33 is provided at the bottom of the fixed block 9 near the connecting plate 18, the bottom of the sealing plate 33 is fitted with the bottom of the second protective block 27, and it is arranged corresponding to the slide groove, and teeth 34 are provided on the side of the sealing plate 33 away from the slide groove, and a mounting opening is provided on the side of the fixed block 9 near the sealing plate 33, and a gear 35 is rotatably connected inside the mounting opening, and the sealing plate 33 is meshed with the gear 35 through the teeth 34, and a rack 36 is meshed on one side of the gear 35 and located inside the fixed block 9, and a second movable groove is provided at the bottom of the fixed end of the first electric push rod 8, and the rack 36 passes through the top of the fixed block 9 and is slidably connected to the second movable groove.

[0041] The sealing plate 33 is used to block and seal the slide groove, thereby further improving the sealing inside the installation groove, so that the second cold air box 31, the cold air pipe and the nozzle 32 can cool the cold air transported inside the installation groove. When the first electric push rod 8 drives the fixed block 9 and the connecting plate 18 to move downward along the slide groove, the fixed block 9 drives the rack 36 to move downward along the second movable groove, so that the gear 35 rotates, and the sealing plate 33 moves upward through the engagement of the teeth 34 and the gear 35, so that the connecting plate 18 can move downward along the slide groove, driving the protective plate 17 to move to the outside of the laser head 7 to protect the laser head 7, thereby facilitating the improvement of the service life of the laser head 7.

[0042] Working principle: When in use, move the box door upwards to fix the aluminum profile inside the placement slot, and use the control device 2 to make the movable structure 3 drive the laser hole opening machine 6 to move to the position where the hole needs to be opened, and then use the sliding block 4 to adjust the mounting block 5, the laser hole opening machine 6 and the laser head 7, so that the laser head 7 is aligned with the position where the hole needs to be opened on the aluminum profile, and the laser hole opening machine 6 and the laser head 7 open the hole. When heat is generated during the hole opening, start the first motor 28 to drive the threaded rod 29 to rotate along the top of the second support plate, so that one side of the movable block 22 moves along the inner wall of the installation slot, and moves up and down along the threaded rod 29, and then start the solenoid valve to spray the cold air inside the second cold air box 31 through the cold air pipe from the nozzle 32, so that the temperature inside the installation slot is reduced to prevent excessive heat from affecting the use of the probe 14. When the hole is opened and detection is required, first move the laser The laser head 7 is separated from the aluminum profile, and the electric telescopic rod 26 is started again to drive the second protective block 27 to move along the bottom of the mounting block 5, so that the two second protective blocks 27 move away from each other and no longer fit together. When the electric telescopic rod 26 contracts and the second protective block 27 moves into the movable groove, the middle position of the bottom of the mounting block 5 is exposed, and the first electric push rod 8 is started again to drive the fixed block 9, the first fixed rod 10 and the connecting block 13 to move downward. When the first electric push rod 8 drives the fixed block 9 and the connecting plate 18 to move downward along the slide groove, the fixed block 9 drives the rack 36 to move downward along the second movable groove, so that the gear 35 rotates, thereby the sealing plate 33 moves upward through the meshing action of the teeth 34 and the gear 35, so that the connecting plate 18 can move downward along the slide groove, driving the protective plate 17 to move to the outside of the laser head 7 to protect the laser head 7.

[0043] When the mounting plate 11 drives the support block 12 to move downward, the two second electric push rods 20 are started at the same time, so that the moving plate 21 drives the movable block 22 to move along the inner wall of the first moving groove, and the moving block 23 moves through the moving opening to drive the support block 12 to move away from the first fixed rod 10, so that the support block 12 can be adjusted according to the size of the hole. When the connecting block 13 drives the probe 14 to move into the hole, the support block 12 moves to the top of the aluminum profile, and the position of the connecting block 13 and the probe 14 is supported and fixed, so that the probe 14 and the connecting block 13 are located in the hole. The center of the hole is formed, and then the control valve is started to transport the cold air inside the first cold air box 15 to the inside of the cavity through the air pipe 16, and then transported to the hole through the through hole on the outside of the connecting block 13 to cool the inner wall of the hole. When the temperature of the inner wall of the hole is reduced, the electric telescopic protective plate 19 is contracted to expose the probe 14, and then the inner wall of the hole is detected by the probe 14, so as to facilitate the inspection of the quality of the hole, check whether the hole diameter, hole depth, hole wall roughness, etc. meet the requirements, analyze the reasons for deviations or defects, adjust the parameters in time, and perform repair operations such as supplementary processing to improve the quality of the opening and facilitate use.
