Common materials for aircraft brake discs include silicon carbide, carbon / carbon composite materials, and high-temperature brazing materials. Among them, grinding equipment is required when polishing the surface of carbon / carbon composite aircraft brake discs.
[0003] Composite material grinding equipment typically consists of the following main components: spindle, grinding wheel, transmission system, and control system. The principle of composite material grinding is to use a rotating grinding wheel to continuously apply force and friction to the workpiece surface, removing uneven or defective parts of the material surface, thereby achieving a smooth and fine machining effect. Depending on the properties of different composite materials and processing requirements, different types, grit sizes, and shapes of grinding wheels can be selected to achieve the best processing results.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0019] Please see Figure 1-3 As shown, a composite material grinding processing device includes a base 1, a control panel 2 mounted on the base 1, a placement table 3 mounted on the base 1, a support frame 4 mounted on the placement table 3, a hydraulic cylinder 5 mounted on the support frame 4, a hydraulic rod 6 mounted on the hydraulic cylinder 5, a fixing frame 7 mounted on the hydraulic rod 6, a drive motor 8 mounted on the fixing frame 7, and a mounting bracket 9 mounted on the output shaft of the drive motor 8. The mounting bracket 9 is rotatably connected to the fixing frame 7. Multiple sets of connecting grooves 10 are formed on the side wall of the mounting bracket 9, and connecting blocks 11 are assembled within the connecting grooves 10. A mounting bracket is fixed on the connecting block 11. The device is equipped with a wheel seat 12, on which a grinding wheel 13 is mounted. A threaded hole is provided on the mounting bracket 9, and a first screw 14 is fitted into the threaded hole. The bottom side of the first screw 14 is rotatably connected to the wheel seat 12. A first knob 15 is mounted on the first screw 14. Scale lines 16 are provided on the side wall of the mounting bracket 9. During operation, existing grinding equipment cannot precisely adjust the grinding accuracy when grinding the composite material aircraft brake disc 25, resulting in low grinding accuracy. By placing the composite material aircraft brake disc 25 on the placement table 3, and using the limiting rod 21 to control the aircraft… When the brake disc 25 is in the limit position, the grinding wheel 13, driven downward by the hydraulic rod 6, comes into contact with the surface of the placement table 3. By rotating the first knob 15, the first screw 14 is driven to rotate, and the first screw 14 moves upward on the mounting bracket 9. The first screw 14 drives the wheel seat 12 to move vertically upward within the mounting bracket 9, and the wheel seat 12 drives the grinding wheel 13 to move vertically upward. According to the scale line 16, the upward movement distance of the grinding wheel 13 can be precisely adjusted according to the thickness of the aircraft brake disc 25. Then, the position of the grinding wheel 13 is finely adjusted downward according to the grinding precision, thus achieving precise adjustment of the grinding precision. Then, the hydraulic rod 6 operates, driving the fixed frame 7 and the mounting frame 9 to move vertically downwards. The mounting frame 9 drives the wheel seat 12 to move vertically downwards, and the wheel seat 12 drives the grinding wheel 13 to move vertically downwards, so that the grinding wheel 13 comes into contact with the surface of the aircraft brake disc 25. Then, the drive motor 8 operates, driving the mounting frame 9 to rotate at high speed. The mounting frame 9 drives the wheel seat 12 to rotate at high speed, and the wheel seat 12 drives the grinding wheel 13 to rotate at high speed, thus realizing the grinding process of the composite material aircraft brake disc 25. This structure allows for precise adjustment of grinding accuracy, which is beneficial to improving grinding precision.
[0020] Please see Figure 4-5As shown, the placement platform 3 has an assembly groove 17 inside, and a lifting plate 18 is slidably connected inside the assembly groove 17. A second screw 19 is rotatably installed on the inner wall of the assembly groove 17, and a second knob 20 is installed on the top side of the second screw 19. The second screw 19 passes through the lifting plate 18, and the lifting plate 18 has a threaded hole. The lifting plate 18 has multiple sets of first rod holes 26, and a limit rod 21 is installed in the first rod hole 26. A limit block 22 is installed on the bottom side of the limit rod 21, and a limit block 22 is installed between the limit block 22 and the inner wall of the assembly groove 17. Equipped with a spring 23, the top plate of the placement platform 3 has multiple sets of second rod holes 24, each containing a limit rod 21. An aircraft brake disc 25 is placed on the placement platform 3. During operation, existing grinding equipment struggles to stably limit the thickness of the composite aircraft brake disc 25, resulting in poor positioning convenience. This is addressed by using a thickness of 25-5... A composite aircraft brake disc 25 with a thickness of 0 mm is placed on a placement platform 3. By rotating the second knob 20, the second screw 19 is rotated, which drives the lifting plate 18 on it to move vertically upward. Since the spring 23 pushes the limiting block 22 to contact the lifting plate 18, the limiting block 22 also moves vertically upward after the lifting plate 18 moves vertically upward. The limiting block 22 drives the limiting rod 21 to move vertically upward. The limiting rod 21 extends out of the second rod hole 24 of the placement platform 3. At the same time, the extension length of the limiting rod 21 is controlled to be less than the thickness of the aircraft brake disc 25. Part of the limiting rod 21 is blocked in the second rod hole 24 by the composite aircraft brake disc 25, while the rest of the limiting rod 21 extends out of the placement platform 3 and surrounds the aircraft brake disc 25, realizing the horizontal positioning of the aircraft brake disc 25. This structure can conveniently limit the thin composite aircraft brake disc 25, so that the aircraft brake disc 25 is in a stable state, which is beneficial to improving the convenience of positioning the composite aircraft brake disc 25.
[0021] Working principle: In the existing grinding process of composite aircraft brake discs 25, the thinness of the composite aircraft brake discs 25 makes it difficult to stably limit their position, resulting in poor positioning convenience. By placing the composite aircraft brake disc 25 (thickness between 25-50 mm) on the placement table 3, rotating the second knob 20 drives the second screw 19 to rotate. The second screw 19 drives the lifting plate 18 on it to move vertically upward. Since the spring 23 pushes the limiting block 22 to contact the lifting plate 18, after the lifting plate 18 moves vertically upward, the limiting block 22 will also... Moving vertically upwards, the limiting block 22 will cause the limiting rod 21 to move vertically upwards. The limiting rod 21 will extend from the second rod hole 24 of the placement platform 3. Simultaneously, the extension length of the limiting rod 21 is controlled to be less than the thickness of the aircraft brake disc 25. Part of the limiting rod 21 is blocked within the second rod hole 24 by the composite material aircraft brake disc 25, while the remaining limiting rod 21 extends from the placement platform 3, surrounding the aircraft brake disc 25, thus achieving horizontal positioning of the aircraft brake disc 25. This structure can conveniently limit the movement of the relatively thin composite material aircraft brake disc 25, keeping it in a stable state and improving the ease of positioning the composite material aircraft brake disc 25. Existing grinding processes... During the grinding process of the composite aircraft brake disc 25, the device cannot precisely adjust the grinding accuracy, resulting in low grinding precision. By placing the composite aircraft brake disc 25 on the placement table 3 and limiting the position of the aircraft brake disc 25 with the limiting rod 21, the grinding wheel 13, driven downwards by the hydraulic rod 6, comes into contact with the surface of the placement table 3. By rotating the first knob 15, the first screw 14 rotates, moving upwards on the mounting bracket 9. The first screw 14 drives the wheel seat 12 to move vertically upwards within the mounting bracket 9, and the wheel seat 12 drives the grinding wheel 13 to move vertically upwards. According to the scale line 16, the upward movement distance of the grinding wheel 13 can be adjusted according to the thickness of the aircraft brake disc 25. After precise adjustment, the position of the grinding wheel 13 is finely adjusted downwards according to the grinding precision, thus achieving precise adjustment of the grinding precision. Then, the hydraulic rod 6 is operated, which drives the fixed frame 7 and the mounting frame 9 to move vertically downwards. The mounting frame 9 drives the wheel seat 12 to move vertically downwards, and the wheel seat 12 drives the grinding wheel 13 to move vertically downwards, so that the grinding wheel 13 is in contact with the surface of the aircraft brake disc 25. Then, the drive motor 8 is operated, which drives the mounting frame 9 to rotate at high speed. The mounting frame 9 drives the wheel seat 12 to rotate at high speed, and the wheel seat 12 drives the grinding wheel 13 to rotate at high speed, thus realizing the grinding process of the composite material aircraft brake disc 25. This structure can precisely adjust the grinding precision, which is beneficial to improving the grinding precision.
