[0031] Working principle and advantages of the present invention: When the aircraft skin automatic cutting equipment is used, the working process is as follows:

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the skin panel to be cut is placed between the upper cross brace plate 5 and the lower cross brace plate 6, and then the clamping screws 7 on the upper cross brace plate 5 and the lower cross brace plate 6 are adjusted to fix the position of the skin panel. The upper and lower clamping screws 7 are used for multi-point support and clamping, and skin panels with various curvatures can be fixed. Then, the adjusting screw 42 is rotated to adjust the horizontal position of the slide 43 and the extension plate 48 thereon, and the height position of the extension plate 48 is adjusted by the adjusting rod 47 and the fastening bolt 1 45, and the inclination angle of the extension plate 48 is adjusted by the ring sleeve 50, the fastening bolt 2 46 and the connecting rod 3 49, so that the two extension plates 48 and the upper surfaces of the left and right sides of the skin panel maintain a smooth transition, and there is no need to make a support frame with a corresponding curvature, which is practical and convenient. (Since the roller 1 27 and the roller 2 39 need to always contact the upper surface of the skin plate, the distance between the laser cutting head 24 and the rollers is not convenient for cutting on the left and right sides of the skin plate, so the extension plates 48 are provided on both sides of the skin plate to solve the above problem)

[0033] As described above, after the skin plate is fixed, the motor 4 is started to drive the screw 8 to rotate, so that the screw 8 drives the sleeve 9 to move to the right through the threaded transmission, and then the sleeve 9 synchronously drives the slide 21, the slide rod 22 and the swing frame 25 at the lower end to move to the right, and the slide rod 22 is lifted so that the swing frame 25 is located above the skin plate, so that the cutting starting point of the laser cutting head 24 is located at the left end of the skin plate, and under the action of the spring 23, the slide rod 22 always presses down the swing frame 25, so that the roller 1 27 and the roller 2 39 on the lower side of the swing frame 25 are always in contact with the upper surface of the skin plate. Continue to move right along the lead screw 8, so that the slide bar 22 drives the swing frame 25 to move right, and while roller 1 27 and roller 2 39 roll on the skin plate, the swing frame 25 swings accordingly due to the curvature of the upper surface of the skin plate, thereby causing the angle between the emission line of the laser cutting head 24 and the tangent at the cutting point of the skin plate to change accordingly, thereby automatically adjusting the distance and the angle between the laser cutting head 24 and the skin plate, and keeping the distance between the laser cutting head 24 and the cutting point of the skin plate as uniform and stable as possible, and keeping the angle stable within a small range, thereby improving the smoothness and uniformity of the cutting surface, and automatic cutting, saving time and effort.

[0034] As described above, while roller 1 27 and roller 2 39 are rolling on the skin plate, Figure 5 and Figure 6 As shown, roller two 39 synchronously drives groove wheel three 40 to rotate, so that groove wheel three 40 drives groove wheel one 33 to rotate through belt 35, and groove wheel one 33 drives the pipe shaft 30 and the brush plate 32 at its lower end to rotate, so that when the swing frame 25 moves right and drives the brush plate 32 to move right, the brush plate 32 also rotates, and the upper surface of the skin plate in front of the cutting point is automatically cleaned.

[0035] As mentioned above, the sleeve 9 drives the slide tube 21 to move rightward while compressing the bellows 13, so that the air in the bellows 13 is subjected to a compression force. Since the conduction direction of the one-way valve 14 points to the inside of the bellows 13, and the conduction direction of the one-way valve 16 points to the sleeve cap 29, the compression force transports the air in the bellows 13 to the sleeve cap 29 through the air pipe 15, and then passes through the inside of the tube shaft 30 and the through hole 41 and is discharged from the center of the bottom surface of the brush plate 32, cleaning the surface of the skin plate while blowing up the dust so that it can be sucked away later, and the airflow will also take away the dust wrapped between the bristles on the bottom surface of the brush plate 32.

[0036] like Figure 4As shown, the screw 8 rotates and drives the outer ring of the ratchet 18 to rotate through the gear 36. At this time, the outer ring of the ratchet 18 can drive the inner ring to rotate through the pawl, so that the inner ring of the ratchet 18 drives the impeller shaft in the pump wheel 17 to rotate, so that the pump wheel 17 applies a suction force to the dust suction pipe 31 through the air intake pipe 38. The suction force sucks away the dust cleaned by the brush plate 32 and transports it to the water tank 19 through the air intake pipe 38. The water in the water tank 19 is used to collect the dust, and the purified air is discharged through the exhaust pipe 20 to prevent the dust from being discharged into the working environment again, thereby realizing surface cleaning and dust suction while automatically cutting the skin panel.

[0037] After the cutting is completed, the skin plate is removed by adjusting each clamping screw 7, and then the motor 4 is used to drive the lead screw 8 to rotate in the reverse direction, so that the sleeve 9 drives the slide cylinder 21 to reset, and the slide cylinder 21 stretches the bellows 13, so that a suction force is obtained in the bellows 13. The suction force draws external air into the bellows 13 through a one-way valve 14, so as to blow away the soot when cutting the next skin plate. When the lead screw 8 rotates in the reverse direction, the outer ring of the ratchet 18 is driven to rotate in the reverse direction through the gear 36. At this time, the outer ring of the ratchet 18 cannot drive the inner ring to rotate through the pawl, so that the inner ring of the ratchet 18 cannot drive the impeller shaft in the pump wheel 17 to rotate, thereby preventing the pump wheel 17 from pumping out the water in the water tank 19 during the resetting of the sleeve 9 and the slide cylinder 21.

[0038] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
