[0021] Working principle and advantages of the present invention: When the continuous hole-making device for aircraft covering parts is used, the working process is as follows: like Figure 1 , Figure 2 and Figure 3 As shown, the cover to be punched is fixed on the drilling platform 3, and the corresponding profiling grooves 25 are fixed on the conveying device 2 according to the connection line of the punching positions. Adjacent profiling grooves 25 are connected by transition grooves 35. In the initial state, Figure 1 As shown, the bellows 21 contracts, the lifting plate 20 is in a high position and contacts the touch switch 3 28 , and at this time, the swing rod 17 moves closer to the ring frame 10 under the action of the spring 2 30 .

[0022] After the installation of the cover and the profiling groove 25 is completed, the controller controls the conveying device 2 and the dust suction pump 44 to work, so that the conveying device 2 drives the drilling platform 3 and the profiling groove 25 to move, so that the slider 26 slides in the profiling groove 25. When the slider 26 is pushed by the profiling groove 25 in a direction perpendicular to the drilling platform 3, the slider 26 drives the hanger 7 and the slide seat 6 on the crossbeam of the gantry 5 through the connecting rod 1 24 to move accordingly. When the touch switch 27 contacts the touch rod 29 on the profiling groove 25, The touch switch 27 transmits the touch signal of the touch rod 29 to the controller, and the controller controls the transmission device 2 to stop working. At this time, the drill rod 15 is just above the drilling position corresponding to the touch rod 29. At the same time, the controller controls the motor 8 and the air pump 22 to work, so that the motor 8 drives the multi-faceted rod 31 to rotate, and the multi-faceted rod 31 drives the pipe shaft 12 to rotate, and then the pipe shaft 12 drives the column rod 14 and the drill rod 15 to rotate. After the air pump 22 works, it delivers air to the bellows 21 through the air pipe 23. Figure 4 As shown, the bellows 21 pushes the lifting plate 20 downward, and the lifting plate 20 drives the pipe shaft 12, the column 14 and the drill rod 15 downward, so that the drill rod 15 approaches the punching position and punches the punching position of the cover. After the drill rod 15 drills a hole, the column 14 drives the friction block 33 to grind and remove burrs on the upper edge, inner wall and lower edge of the hole, thereby improving the hole making quality. When the lifting plate 20 contacts the touch switch 19, the touch switch 19 transmits the touch signal of the lifting plate 20 to the controller, and controls The controller controls the air pump 22 to work in reverse, so that the bellows 21 contracts and drives the lifting plate 20 to move upward, so that the lifting plate 20 drives the pipe shaft 12, the column rod 14 and the drill rod 15 to move upward, and when the lifting plate 20 is reset and contacts with the touch switch 3 28, the touch switch 3 28 transmits the touch signal of the lifting plate 20 to the controller, and the controller controls the air pump 22 and the motor 8 to stop working, and controls the conveying device 2 to work again, and punches the next punching position, realizing automatic and continuous positioning punching, which greatly improves the hole making efficiency.

[0023] As described above, during the downward movement of the lifting plate 20, the ring frame 2 13 is also driven downward by the spring 16, and the ring frame 2 13 is moved downward through the rocker 17 and the rolling drum 18, and the rolling drum 18 contacts the surface of the covering member before the drill rod 15. When the rolling drum 18 contacts the covering member, the rolling drum 18 rolls in a direction away from the punching position, so that the rolling drum 18 rolls and flattens the covering member at the punching position, so as to improve the accuracy of the drilling of the drill rod 15, and while the rolling drum 18 rolls in a direction away from the punching position, the rocker 17 stretches the spring 2 30, so that the spring 2 30 obtains a restoring force. When the lifting plate 20 moves upward, the pressure of the spring 16 on the ring frame 2 13 gradually decreases, and under the action of the restoring force of the spring 2 30, the ring frame 2 13 moves upward and resets, and at the same time, the rocker 17 drives the rolling drum 18 to roll in a direction close to the punching position and resets.

[0024] like Figure 6 and Figure 7 As shown, when the slider 26 slides in the profiling groove 25, the connecting rod 1 24 drives the dust cover 37 to move in the profiling groove 25 through the connecting rod 2 36, so that the walking wheel 41 rolls on the upper surface of the profiling groove 25, so that the walking wheel 41 drives the gear 2 42 to rotate through the shaft rod 43, and when the gear 2 42 rotates, the U-shaped scraper 39 is driven to rotate in the profiling groove 25 through the gear 1 40 and the shaft sleeve 2 38, so that the U-shaped scraper 39 scrapes off the dirt on the bottom and inner wall of the groove, and the dust pump 44 sucks the dirt in the profiling groove 25 through the air pipe 2 45 and the dust cover 37 and transports it to the collection box 46, so as to ensure that the profiling groove 25 is clean and avoid dirt blocking the smooth sliding of the slider 26, thereby improving the drilling accuracy. After the hole making is completed, the cover can be removed from the drilling platform 3.
