Therefore, this utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figure 1 - Figure 4 shown, this utility model provides a clamping device for processing parts of a space shuttle, including a processing table 1. A clamping mechanism 4 is installed on one side of the processing table 1, and an adjusting mechanism 3 is installed on one side of the clamping mechanism 4. The clamping mechanism 4 includes a moving block 44. One end of the moving block 44 is rotatably connected to a second rotating rod 48. A clamping block 46 is fixedly connected to the outside of the second rotating rod 48. A positioning plate 31 is fixedly connected to one side of the clamping block 46. The adjusting mechanism 3 includes a first rotating rod 33. One end of the first rotating rod 33 is fixedly connected to one end of the second rotating rod 48. A transmission gear 32 is fixedly connected to the outside of the first rotating rod 33. A shifting rack 34 is meshed with one side of the transmission gear 32. A pushing block 36 is fixedly connected to one side of the shifting rack 34. An electric push rod 35 is fixedly connected to one end of the pushing block 36; One side of the shifting rack 34 is slidably connected to a guide rail 37. One side of the guide rail 37 is fixedly connected to one side of the moving block 44, and the other side of the guide rail 37 is fixedly connected to one side of the electric push rod 35.

[0024] The electric push rod 35 works to drive the moving block 36 to move, and the displacement rack 34 moves accordingly. The displacement rack 34 slides inside the guide rail 37, and the fixed displacement rack 34 moves in a straight line. The displacement rack 34 meshes with the transmission gear 32, driving the transmission gear 32 to rotate. By controlling the movement distance of the displacement rack 34, the transmission gear 32 rotates 90 degrees, successively driving the first rotating rod 33, the second rotating rod 48, and the clamping block 46 to rotate. When the clamping block 46 rotates to the vertical direction, the inner wall of the aircraft part can be clamped by multiple clamping blocks 46, improving the application range of the device and reducing the replacement time of the fixture.

[0025] Embodiment 2: As Figure 2 and Figure 4 shown, the clamping mechanism 4 further includes a fixed frame 43. One side of the fixed frame 43 is fixedly connected to one side of the processing table 1. An opening groove 49 is formed inside the fixed frame 43, and the moving block 44 is arranged inside the opening groove 49; an opening 412 is formed inside the moving block 44, and a rotating roller 413 is rotatably connected inside the opening 412; a connecting rod 411 is rotatably connected inside the opening 412, and one end of the connecting rod 411 is fixedly connected to a sliding block 47; an installation frame 2 is fixedly connected to one side of the processing table 1, a hydraulic cylinder 41 is fixedly connected to one side of the installation frame 2, one end of the hydraulic cylinder 41 is fixedly connected to a moving plate 42, one end of the moving plate 42 is fixedly connected to a pushing plate 45, and one end of the pushing plate 45 sequentially passes through the moving plate 42 and the opening groove 49; sliding grooves 410 are formed on both sides of the pushing plate 45, and the outside of the sliding block 47 is slidably connected to the inside of the sliding grooves 410.

[0026] The overall effect achieved by this entire embodiment is that the hydraulic cylinder 41 works to drive the moving plate 42 to move, and the pushing plate 45 moves accordingly. The sliding grooves 410 are formed on both sides of the pushing plate 45 and are inclined. During the movement of the sliding grooves 410 along with the pushing plate 45, the sliding block 47 slides inside the sliding grooves 410, and the rotating roller 413 contacts the inclined surface of the pushing plate 45, driving the moving block 44 to move horizontally and driving the position of the clamping block 46 to move. Thus, the distance between the clamping blocks 46 is adjusted according to different parts, and parts of different sizes are clamped to prevent the parts from shifting during the processing.

[0027] Usage method and working principle of this device: The working of the hydraulic cylinder 41 drives the movement of the moving plate 42, and the pushing plate 45 moves accordingly. The sliding block 47 slides inside the sliding groove 410, and the rotating roller 413 contacts the inclined surface of the pushing plate 45, pushing the moving block 44 to move in the horizontal direction, driving the movement of the position of the clamping block 46, clamping parts of different sizes. The working of the electric push rod 35 drives the movement of the pushing block 36, and the displacement rack 34 makes a linear motion accordingly, driving the rotation of the transmission gear 32, successively driving the first rotating rod 33, the second rotating rod 48 and the clamping block 46 to rotate, adjusting the direction of the clamping block 46, and clamping the inside of the automotive parts.

[0028] The above are only the preferred embodiments of the present invention, and are not limitations to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still belong to the protection scope of the technical solution of the present invention.
