[0030] Working principle and advantages of the present invention: When the aircraft propeller punching device is in use, the working process is as follows:

[0031] like Figure 1 and Figure 6As shown, the hub of the propeller is placed on the support cylinder seat 7, and the column rod 13 is located between two adjacent blades. The motor 4 is started to work, so that the motor 4 drives the drill rod 5 to rotate. After the propeller is placed, the cylinder 3 is started to work so that the cylinder 3 pushes the lifting plate 6 to move downward, so that the lifting plate 6 drives the pressing plate 25 and the pressing plate 3 31 to move downward through the push-pull rod 1 24 and the push-pull rod 2 30 respectively, so that the pressing plate 25 compresses the spring 4 27 and applies downward pressure to the piston plate 1 28 through the spring 4 27, so that the piston plate 1 28 transports the air inside the slide cylinder 3 26 to each slide cylinder 10 through the air pipe 1 29, as shown in FIG. Figure 5 As shown, the air pressure in the slide cylinder 10 increases, and the piston plate 3 48 applies downward pressure to the connecting rod 12 through the connecting rod 2 49, so that the connecting rod 12 drives the ring frame 11 and the column rod 13 to move downward synchronously. At the same time, the connecting rod 12 compresses the spring 15, so that the spring 15 obtains a restoring force, as shown in FIG. Figure 2 As shown, the ring frame 11 synchronously drives the slide bar 36 and the slot plate 37 thereon to move downward, so that the slot plate 37 drives the push rod 40 to move toward the inside of the support cylinder seat 7 through the strip through hole 39 and the pin rod 38, and the push rod 40 compresses the spring six 43 and drives the clamping plate 42 to apply an extrusion force to the peripheral wall of the propeller hub through the spring six 43, thereby playing a role in clamping and centering the propeller hub, which helps to improve the accuracy of drilling holes in the hub. When the column rod 13 moves downward, it drives the pressure plate 14 to move downward. Figure 3 and Figure 4 As shown, under the action of the slide groove 22 and the slider 23, the column rod 13 simultaneously drives the pressure plate 14 to rotate and move to the top of the corresponding blade. When the pressure plate 14 moves downward, it drives the pressure rod 20 downward. When the lower end of the pressure rod 20 contacts the blade, the reaction force it receives compresses the spring three 21.

[0032] As the lifting plate 6 moves downward, when the pressure plate three 31 contacts the upper end of the spring five 33, the slider 23 is located at the lowermost end of the slide groove 22. At this time, the pressure plate one 14 rotates 90° and is located directly above the corresponding blade. When the pressure plate three 31 continues to move downward and compresses the spring five 33, the spring five 33 applies downward pressure to the piston plate two 34, so that the piston plate two 34 transports the air in the slide cylinder four 32 to each slide cylinder two 16 and slide cylinder five 44 through the air pipe two 35, so that the slide plate one 17 compresses the spring two 18, and at the same time, the slide plate one 17 pushes the locking rod one 19 to approach the pressure rod 20, and at the same time, the slide plate two 45 compresses the spring seven 47, and the slide plate two 45 drives the locking rod two 46 to approach the push rod 40. When the lower end of the drill rod 5 is about to contact the upper surface of the propeller hub The teeth at the end of the locking rod 19 engage with the teeth on the peripheral wall of the pressure rod 20 to lock the pressure rod 20, thereby ensuring a stable downward pressure on the blades. At the same time, the teeth at the end of the locking rod 46 engage with the teeth on the peripheral wall of the push rod 40 to lock the push rod 40, thereby ensuring a stable radial clamping force on the wheel hub. As the lifting plate 6 drives the drill rod 5 to continue to move downward, the drill rod 5 drills the wheel hub, and in this process, the pressure plates 25 and 31 continue to compress the springs 4 27 and 5 33, thereby obtaining a stronger clamping force and locking force, ensuring the stability of the drilling process and improving the drilling accuracy. In addition, propellers with different diameters of hubs and blades with different curvature surfaces can be self-adjusted and clamped, which increases the scope of use and greatly reduces the difficulty of operation.

[0033] After the drilling is completed, the cylinder 3 is started to drive the lifting plate 6 to move upward, so that the lifting plate 6 drives the drill rod 5 to move upward, and the lifting plate 6 drives the pressure plate 25 and the pressure plate 31 to move upward through the push-pull rod 1 24 and the push-pull rod 2 30 respectively. When the drill rod 5 just leaves the upper surface of the wheel hub, as the compression force of the spring 5 33 becomes smaller, the slide plate 17 drives the locking rod 19 away from the pressure rod 20 and resets it under the action of each spring 2 18 and the spring 7 47, and the slide plate 2 45 drives the locking rod 2 46 away from the push rod, thereby releasing the lock of the pressure rod 20 and the push rod 40, and as the compression force of the spring 4 27 becomes smaller, under the restoring force of the spring 15, the connecting rod 12 moves upward, and drives the piston plate 3 48 to move upward and reset through the connecting rod 2 49, and the connecting rod 12 drives the column rod 13 and the ring frame 11 while moving upward The ring frame 11 moves upward, and the groove plate 37 is driven upward and reset through the slide bar 36, so that the push rod 40 moves to the outside of the support cylinder seat 7 under the action of the strip through hole 39 and the pin rod 38, and the push rod 40 drives the clamping plate 42 away from the hub through the spring six 43. At the same time, the column rod 13 moves upward and drives the pressure plate 14 to move away from the corresponding blade, and rotates in the opposite direction and resets under the action of the slider 23 and the slide groove 22, so as to release the fixation of the propeller, and the propeller after the punching process can be removed from the support cylinder seat 7, and then the next propeller to be punched is placed. According to the above process, fast clamping and punching can be achieved without complicated operations, and propellers with hubs of different diameters and blades of different curvature surfaces can be clamped by themselves, which greatly improves the working efficiency.
