[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1-4 The figure shows a smoothness processing device for aerospace shell manufacturing, including a main box 1, a top plate 2 is fixedly installed on the top surface of the main box 1, and telescopic frames 3 are fixedly installed at both ends of the top surface of the top plate 2, and a fixed plate 4 is fixedly installed on the top surface of the telescopic frame 3. A fixed shaft 5 is provided inside the fixed plate 4, and a moving head 6 is provided on the outer surface of the fixed shaft 5. A polishing assembly 7 is installed on the bottom surface of the moving head 6. Among them, the telescopic frame 3, the moving head 6 and the polishing assembly 7 are all existing mature technologies, and their working principles are not described in detail here. A prevention frame 8 is provided in the middle of the top surface of the top plate 2, and the prevention frame 8 is fixedly installed on the top surface of the top plate 2. Two splints 13 are provided on the top surface of the prevention frame 8. Among them, supporting legs 9 are fixedly installed at the four corners of the bottom surface of the main box 1, and supporting foot pads 10 are fixedly installed on the bottom surface of the supporting legs 9. The support legs 9 and supporting foot pads 10 are provided to ensure the stability of the entire device when the device is in use.

[0025] See also Figure 1-4 As shown in the figure, there are two clamping grooves 11 running through the top surface of the prevention frame 8, and the inside of the two clamping grooves 11 are movably clamped with a clamping block 12. The two clamping plates 13 are fixedly installed on the top surfaces of the two clamping blocks 12 respectively. A gear disk 15 is rotatably installed in the middle of the bottom surface of the prevention frame 8, and a straight tooth plate 14 is fixedly installed on one side surface of the clamping block 12. The two straight tooth plates 14 are arranged opposite to each other and mesh with the gear disk 15. A servo motor 16 is fixedly installed on the top surface of the top plate 2, and the output end of the servo motor 16 is fixedly connected to the bottom surface of the gear disk 15.

[0026] In this embodiment: when clamping the shell, it is only necessary to place the shell to be clamped in the middle of the top surface of the prevention frame 8, and then start the servo motor 16. When the servo motor 16 rotates clockwise, it can drive the gear plate 15 to rotate clockwise on the bottom surface of the prevention frame 8, thereby driving the two straight tooth plates 14 to move toward each other, thereby driving the clamping block 12 to slide inside the clamping groove 11, and since the clamping plate 13 is fixedly installed on the top of the clamping block 12, it can drive the clamping plate 13 to move toward each other on the top surface of the prevention frame 8, until the two clamping plates 13 stably clamp the shell, and then the rotation of the servo motor 16 can be stopped. In this process, it can effectively ensure that the two clamping plates 13 can move synchronously, avoiding the disadvantages of the existing clamping device that cannot ensure the synchronous movement of the two clamping plates 13.

[0027] See also Figure 1-4 In the figure, the internal movable clamp of the splint 13 is connected with a clamping plate 17, and a buffer column 18 is arranged between the clamping plate 17 and the inner surface of the splint 13. The buffer column 18 includes a fixed sleeve 19, and the internal movable sleeve of the fixed sleeve 19 is connected with a movable column 20. A spring 21 is arranged between the movable column 20 and the fixed sleeve 19. One end of the spring 21 is fixedly connected to the bottom surface of the movable column 20, and the other end of the spring 21 is fixedly connected to the inner bottom surface of the fixed sleeve 19.

[0028] In this embodiment: during the process of clamping the shell, the clamping plate 17 first contacts the shell. As the servo motor 16 continues to rotate, the clamping plate 17 will shrink to the inside of the clamping plate 13 under the action of the buffer column 18. At this time, the spring 21 is in a taut state. After the spring 21 shrinks to the point where it can no longer shrink, the shell can be stably clamped, avoiding the problem of the existing rigid clamping easily damaging the shell.
