[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: a central drilling machine for civil aircraft processing, comprising a bracket 1, a drilling platform 2 is fixedly connected to the middle of the bracket 1, a mounting frame 3 is fixedly connected to the upper part of the drilling platform 2, a drilling assembly 25 is arranged inside the mounting frame 3, and the drilling assembly 25 is used for processing aircraft parts, a first motor 6 is arranged at the lower part of the drilling platform 2, a rotating rod 7 is fixedly connected to the output end of the first motor 6, a rotating disk 8 is rotatably connected to the top of the rotating rod 7, sliding rings 11 are arranged on both sides of the rotating disk 8, guide grooves 9 are opened on both sides of the rotating disk 8, and a plurality of sliding rings 11 are slidably connected to the inside of the plurality of guide grooves 9, slide rails 10 are fixedly connected to both sides of the upper part of the drilling platform 2, a plurality of slide rails 10 are slidably connected to the outside of the plurality of slide rails 10, and a plurality of slide rings 11 are rotatably connected at the other end It is connected to the outside of multiple sliders 12, and the upper parts of multiple sliders 12 are fixedly connected with connecting plates 13, and the outsides of multiple connecting plates 13 are fixedly connected with arc-shaped clamping plates 14, and the insides of multiple arc-shaped clamping plates 14 are provided with protective pads 15, and the material of multiple protective pads 15 is rubber material. The lower part of the drilling platform 2 is fixedly connected with a U-shaped frame 5, and the first motor 6 is fixedly connected to the inside of the U-shaped frame 5. The drilling assembly 25 includes an electric push rod 2501, and the electric push rod 2501 is fixedly connected to the inside of the mounting frame 3. The output end of the electric push rod 2501 is fixedly connected to the mounting shell 2502, and the inside of the mounting shell 2502 is fixedly connected to the third motor 2503, and the output end of the third motor 2503 is fixedly connected to the mounting plate 2504, and the mounting plate 2504 is installed with a drill bit 2505.
[0024] When processing aircraft parts, first, the aircraft parts are placed in the middle of the three arc-shaped clamping plates 14. Then, the first motor 6 is started, and the first motor 6 starts to run, driving the rotating rod 7 fixed at its output end to rotate. The rotation of the rotating rod 7 further drives the rotating disk 8 fixed on the top to start rotating. As the rotating disk 8 rotates, the three sliding rings 11 connected to the rotating disk 8 also slide inside the three guide grooves 9. In the process of the sliding ring 11 moving in the guide groove 9, the three sliders 12 connected thereto are pushed to move toward the middle of the rotating disk 8 along the three slide rails 10. In the process of the slider 12 moving, the three connecting plates 13 fixed on the upper part thereof also move accordingly. The movement of the three connecting plates 13 drives the three arc-shaped clamping plates 14 fixed outside to move synchronously. As the arc-shaped clamping plate 14 moves, the three protective pads 15 fixed inside the arc-shaped clamping plate 14 also move accordingly until the three protective pads 15 are in close contact with the outer surface of the aircraft parts. This process ensures that the aircraft parts are firmly fixed during processing. After the parts are fixed, the operator only needs to release his hands to achieve automatic and stable fixation of the aircraft parts. This fixing method improves the convenience and reliability of processing aircraft parts. Compared with the traditional vise fixing method, this method overcomes the problem that the vise cannot provide sufficient stability during high-speed processing, thereby effectively preventing the displacement and error of the workpiece caused by vibration during processing. When drilling, the position of the drill bit 2505 is easily adjusted by setting the electric push rod 2501. By starting the third motor 2503 to rotate the mounting plate 2504 fixed at the output end, the mounting plate 2504 rotates and the drill bit 2505 installed inside rotates, thereby realizing the automatic drilling operation.
[0025] Reference Figure 1 and Figure 2 , mounting blocks 16 are fixedly connected on both sides of the bracket 1, a second motor 17 is fixedly connected inside the left mounting block 16, a screw rod 18 is fixedly connected to the output end of the second motor 17, a moving block 19 is threadedly connected to the outside of the screw rod 18, a limiting block 20 is fixedly connected to the rear side of the outside of the moving block 19, a transparent baffle plate 22 is fixedly connected to the outside of the moving block 19, the transparent baffle plate 22 is made of an acrylic plate, a guide ring 23 is fixedly connected to the right side of the outside of the transparent baffle plate 22, a through hole 4 is opened inside the drilling platform 2, the transparent baffle plate 22 is slidably connected to the inside of the through hole 4, a limiting groove 21 is opened inside the left mounting block 16, the limiting block 20 is slidably connected to the inside of the limiting groove 21, a guide rod 24 is fixedly connected to the inside of the right mounting block 16, and the guide ring 23 is slidably connected to the outside of the guide rod 24.
[0026] When drilling a part, first start the second motor 17. The second motor 17 starts running, driving the screw 18 fixed at its output end to rotate. As the screw 18 rotates, the moving block 19 threaded on the screw 18 starts to move upward. In the process of moving the moving block 19 upward, it drives the transparent shielding plate 22 fixed on the outside thereof to rise synchronously. The transparent shielding plate 22 gradually moves to the top of the drilling platform 2 through the through hole 4 on the drilling platform 2 to cover the drilling area. In this way, the transparent shielding plate 22 can effectively shield the drilling area, so that when drilling civil aircraft parts, it is convenient to shield the drilling area. The shielding can effectively prevent flying chips from splashing and protect the safety of the operator.
[0027] Working principle: When processing aircraft parts, first, place the aircraft parts in the middle of the three arc-shaped clamping plates 14, and then start the first motor 6. The first motor 6 rotates the rotating rod 7 fixed at the output end, and the rotating rod 7 rotates to rotate the rotating disk 8 fixed on the top. The rotating disk 8 rotates to move the three sliding rings 11 inside the three guide grooves 9. When the three sliding rings 11 move, the three sliders 12 move outside the three slide rails 10 toward the middle of the rotating disk 8. When the three sliders 12 move, the three connecting plates 13 fixed on the top move. The three connecting plates 13 move to move the three arc-shaped clamping plates 14 fixed on the outside. The three arc-shaped clamping plates 14 move to move the three protective pads 15 set inside. The aircraft parts can be fixed by the three protective pads 15 contacting the outside of the aircraft parts. After the fixation is completed, just release your hand, which makes it easy to fix the civil aircraft parts when processing them, solves the problem that the fixation method of the vise cannot provide sufficient stability and easily causes vibration of the workpiece, and improves the quality and accuracy of workpiece processing. Then, when drilling the parts, start the second motor 17, and the second motor 17 drives the screw rod 18 fixed at the output end to rotate. The screw rod 18 rotates and drives the moving block 19 connected with the external thread to move upward. When the moving block 19 moves, it drives the externally fixed transparent shielding plate 22 to move, so that the transparent shielding plate 22 moves through the through hole 4 to the upper part of the drilling platform 2 to shield the drilling area. When drilling the civil aircraft parts, it is easy to shield the drilling area. The shielding can effectively prevent flying chips from splashing and protect the safety of the operator.
