Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] Example 1:

[0018] refer to Figure 1-4A tooling table for machining oblique holes in aircraft carbon fiber seat backrests includes a support platform 1. A first support seat 2 is rotatably connected to the top of the support platform 1. A second support seat 3 is fixedly connected to one side of the first support seat 2. Two first pressure blocks 4 are inserted into the top of the first support seat 2. The first pressure blocks 4 have positioning holes 5 inside. Two second pressure blocks 6 are inserted into the top of the second support seat 3. A cylinder 7 is rotatably connected to the top of the support platform 1. The telescopic end of the cylinder 7 is hinged to the second support seat 3. Two linear drive mechanisms 8 are installed on the top of the support platform 1. An electric drill 9 is installed on the top of the linear drive mechanism 8.

[0019] Specifically, the bottoms of the first pressure block 4 and the second pressure block 6 are both fixedly connected to insert blocks, and the tops of the first support base 2 and the second support base 3 are both provided with slots that match the insert blocks. By setting the first support base 2 and the second support base 3 in conjunction with the first pressure block 4 and the second pressure block 6, this device can quickly and stably press the back of the aircraft seat, effectively avoiding displacement during processing and significantly improving clamping efficiency. The linear drive mechanism 8 drives the electric drill 9 to perform oblique drilling through the positioning hole 5, ensuring the consistency of the drilling angle and processing accuracy. At the same time, the design of the cylinder 7 driving the support base to rotate enables the workpiece to complete the processing of oblique holes on both sides in a single clamping, completely solving the problem of traditional tooling requiring two sets of fixtures and repeated clamping, thus improving production efficiency. This device is easy to operate, reduces the labor intensity of workers, and ensures the stability of processing quality. It is particularly suitable for batch production needs and has high practicality and economy.

[0020] refer to Figure 4 The linear drive mechanism 8 includes a housing 81, the bottom of which is fixedly connected to the support platform 1. A threaded shaft 82 is rotatably connected inside the housing 81. A stepper motor 83 is fixedly connected to the surface of the housing 81. The output end of the stepper motor 83 is bolted to the threaded shaft 82 via a coupling. A moving block 84 is threadedly connected to the surface of the threaded shaft 82. By starting the stepper motor 83, the threaded shaft 82 is driven to rotate, and the threaded shaft 82 drives the moving block 84 to move, so that the moving block 84 drives the electric drill 9 to drill holes in the back of the aircraft seat.

[0021] refer to Figure 4 The movable block 84 has a sliding rod 85 inside, and both ends of the sliding rod 85 are fixedly connected to the housing 81. The top of the movable block 84 is fixedly connected to the electric drill 9. The movable block 84 can move stably by sliding on the surface of the sliding rod 85.

[0022] refer to Figure 2 and Figure 3The top of the support platform 1 is provided with an arc-shaped groove 10. The front and back of the second support base 3 are fixedly connected with brackets 11. The bottom of the brackets 11 is rotatably connected with a bearing 12. The inside of the arc-shaped groove 10 is slidably connected with the bearing 12. The arc-shaped groove 10 and the first support base 2 rotate around the same center. The second support base 3 drives the bearing 12 to slide in the arc-shaped groove 10, which can effectively improve the stability of the rotation of the first support base 2 and the second support base 3.

[0023] Brief description of the usage process: The user can place the aircraft seat back on top of the first support base 2 and the second support base 3, insert the first pressure block 4 into the first support base 2, and then insert the second pressure block 6 into the second support base 3. The first pressure block 4 and the second pressure block 6 press the aircraft seat back tightly. Then, start the electric drill 9, so that the linear drive mechanism 8 drives the electric drill 9 to drill a hole at an angle on one side of the aircraft seat back through the positioning hole 5. After processing one side, start the cylinder 7 to drive the first support base 2 and the second support base 3 to rotate on the top of the support platform 1. Then, the other side of the aircraft seat back can be drilled at an angle.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
