[0023] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0024] Combined with Figure 1 , a flipping structure of a missile centroid measurement platform includes a support base 1, a flipping mechanism 2 is fixedly installed on the upper part of the support base 1, limiting mechanisms 3 are arranged on both sides of the flipping mechanism 2, the limiting mechanisms 3 are fixedly installed on both sides of the upper part of the support base 1, a missile fixing mechanism 4 is hinged to the upper part of the flipping mechanism 2, and the lower part of the missile fixing mechanism 4 is movably connected to the upper part of the support base 1.

[0025] Combined with Figure 1 , a groove is provided inside the support base 1 to facilitate the installation of other mechanisms.

[0026] Combined with Figure 1 and Figure 2, the flipping mechanism 2 includes an electric push rod support 21. The electric push rod support 21 is fixedly installed on one side of the inner groove of the support base 1. On the upper side of the electric push rod support 21, an electric push rod 22 is fixedly installed. At the top of the electric push rod 22, a baffle 23 is fixedly installed. On the upper side of the baffle 23, a weight sensor 24 is fixedly installed. On the upper side of the weight sensor 24, a hinge assembly 25 is fixedly installed. On the upper side of the electric push rod support 21, an electric push rod 26 is fixedly installed. At the top of the electric push rod 26, a baffle 23 is fixedly installed. On the upper side of the baffle 23, a weight sensor 24 is fixedly installed. On the upper side of the weight sensor 24, a movable hinge assembly 27 is fixedly installed. The movable hinge assembly 27 includes a fixed hinge support 271. The lower side of the fixed hinge support 271 is fixedly connected to the weight sensor 24. The upper side of the fixed hinge support 271 is hinged with a sliding hinge support 272.

[0027] Combined with Figure 3 , Figure 4 and Figure 5 The limiting mechanism 3 includes a first fixing plate 31. One side of the first fixing plate 31 is fixedly connected to the inner groove of the support base 1. The first fixing plate 31 is arranged on one side of the electric push rod 22. An upper part of the first fixing plate 31 is connected through a movable limiting component 32. The movable limiting component 32 includes a movable limiting block 321. The movable limiting block 321 penetrates through the first fixing plate 31. One end of the movable limiting block 321 is fixedly connected to an electric telescopic device 322. One side of the electric telescopic device 322 is fixedly connected to a fixed block 323. The fixed block 323 is fixedly installed on the upper side of the support base 1. On one side of the upper part of the first fixing plate 31, a first limiting block 33 is fixedly installed. At one end of the support base 1 away from the first fixing plate 31, a second fixing plate 34 is fixedly installed. The second fixing plate 34 is located on one side of the electric push rod 26. On one side of the second fixing plate 34, a second limiting block 35 is fixedly installed.

[0028] Under the upward push of multiple groups of electric push rods 22 and 26, the baffle 23, weight sensor 24, and hinged assembly 25 installed on the electric push rod 22 move upward with the electric push rod 22. The baffle 23, weight sensor 24, and movable hinged assembly 27 installed on the electric push rod 26 move upward with the electric push rod 26. When performing horizontal measurement, the electric telescopic device 322 pushes the movable limit block 321 through the first fixing plate 31, so that the movable limit block 321 is located above the baffle 23 installed on the electric push rod 22. When the upward movement of the baffle 23 is restricted by the movable limit block 321, the electric push rod 22 stops pushing upward. When the baffle 23 installed on the electric push rod 26 is restricted by the second limit block 35 fixedly installed on one side of the second fixing plate 34, the electric push rod 26 stops pushing upward. The lower parts of the movable limit block 321 and the second limit block 35 are at the same horizontal plane. When performing tilt measurement, the electric push rod 22 moves downward a certain distance, and the electric telescopic device 322 pulls the movable limit block 321 through the first fixing plate 31, so that the movable limit block 321 does not affect the upward movement of the baffle 23. After the movement of the movable limit block 321 is completed, the electric push rod 22 continues to push upward. When the movement of the baffle 23 installed on the electric push rod 22 is restricted by the first limit block 33, the electric push rod 22 stops working.

[0029] Combined with Figure 4 and Figure 6 Figure, the missile fixing mechanism 4 includes a load-bearing platform 41. One side below the load-bearing platform 41 is fixedly connected to the hinged assembly 25. A groove 411 is formed on the side away from the hinged assembly 25 below the load-bearing platform 41. The load-bearing platform 41 is slidably connected to the movable hinged assembly 27 through the groove 411. A missile fixing clamp 42 is fixedly installed above the load-bearing platform 41. A snap ring 43 is movably hinged above the missile fixing clamp 42. A support rod 44 is fixedly installed below the load-bearing platform 41. The lower part of the support rod 44 is movably connected to a fixed support base 45. The fixed support base 45 is fixedly installed on the support base 1.

[0030] When not working, the load-bearing platform 41 is connected to the fixed support base 45 through the support rod 44 fixedly installed below. When working, the missile is fixed above the load-bearing platform 41 through the missile fixing clamp 42 and the snap ring 43 movably hinged above. The load-bearing platform 41 rises upward under the action of the flipping mechanism 2, and the load-bearing platform 41 is separated from the fixed support base 45 through the support rod 44 fixedly installed below.

[0031] Working principle: The missile is fixed on the load-bearing platform 41 through the missile fixing fixture 42 and the snap ring 43. At this time, the first electric push rod 22 and the second electric push rod 26 do not work. The load-bearing platform 41 transfers the gravity to the fixed support seat 45 through the lower support rod 44. When the horizontal measurement starts, the electric telescopic device 322 pushes the movable limit block 321 through the first fixing plate 31, so that the movable limit block 321 can block the baffle 23. The first electric push rod 22 and the second electric push rod 26 push upward to lift the load-bearing platform 41. When the baffle 23 above the first electric push rod 22 is blocked by the movable limit block 321, the first electric push rod 22 stops pushing. When the baffle 23 above the second electric push rod 26 is blocked by the second limit block 35, the second electric push rod 26 stops working. At this time, the load-bearing platform 41 is in a horizontal state, and the value of the weight sensor 24 is recorded. Subsequently, the first electric push rod 22 moves downward a certain distance, and the electric telescopic device 322 pulls the movable limit block 321 so that the movable limit block 321 does not block the baffle 23. The first electric push rod 22 continues to push upward until the baffle 23 above it is blocked by the first limit block 33, and then the first electric push rod 22 stops working. At this time, the load-bearing platform 41 is in an inclined state, and the value of the weight sensor 24 is recorded. The centroid of the missile is calculated through the values recorded twice and the preset inclination angle of the load-bearing platform 41.
