[0002] A dynamic balancing machine is a type of balancing machine used to measure the size and position of the imbalance of a rotating object (rotor). The main performance of a dynamic balancing machine is based on two comprehensive indicators: the minimum achievable residual imbalance and the dynamic balancing machine reduction rate. The former is the minimum value of the residual imbalance that the balancing machine can make the rotor reach, and it is an indicator to measure the maximum balancing ability of the balancing machine; the latter is the ratio of the reduced imbalance after one correction to the initial imbalance. For example, the dynamic balancing machine model YYW-3000D can detect the rotor of the intelligent positioning model aircraft.

[0025] The protective assembly 4 includes a protective cover 41 fixedly mounted on the top of the dynamic balancing machine base 1, a moving frame 42 is slidably connected inside the protective cover 41, and a fitting groove is provided at one end of the moving frame 42 corresponding to one end of the protective cover 41, the moving frame 42 moves inside the protective cover 41 along the fitting groove to increase the area of ​​the protective cover 41, the outer side of the moving frame 42 and the inner wall of the fitting groove fit each other, one end of the moving frame 42 is symmetrically slidably connected with a protective plate 47, the protective plate 47 enters one end of the moving frame 42 to block the one end of the moving frame 42 to prevent the outside wind from blowing into the moving frame 42.

[0026] like Figure 1 and Figure 2 As shown, a spring rod 43 is embedded in the middle of the top of the moving frame 42 and the spring rod 43 is slidably connected to the inside of the protective cover 41. The top of the spring rod 43 is clamped and connected to a squeezing plate 44, and the bottom end of the squeezing plate 44 and the top of the protective cover 41 fit each other. The tensile force of the spring rod 43 drives the squeezing plate 44 to move, and the squeezing plate 44 fits with the top of the protective cover 41 after movement, thereby achieving the purpose of squeezing and fixing the moving frame 42, thereby preventing the moving frame 42 from self-sliding.

[0027] like Figure 3 and Figure 4 As shown, a positioning groove 45 is provided on one end surface of the movable frame 42, a first magnet 46 is clamped and installed at the middle position of the positioning groove 45 on one end surface of the movable frame 42, and second magnets 49 are clamped and installed at both ends of the positioning groove 45 on one end surface of the movable frame 42. The first magnet 46 and the second magnet 49 can facilitate the adsorption of other objects, and an iron block 48 is slidably connected between the first magnet 46 and the second magnet 49 inside the positioning groove 45. The iron block 48 is used for adsorption between the first magnet 46 and the second magnet 49, thereby achieving the purpose of fixing the iron block 48.

[0028] like Figure 3As shown, one end of the iron block 48 is clamped and installed inside the protective plate 47. The iron block 48 is used to limit the protective plate 47. The bottom end of the protective plate 47 is rotatably connected with a positioning column 410. A guide groove 5 is provided at the top of the dynamic balancing machine base 1 corresponding to the bottom position of the outer surface of the positioning column 410. The positioning column 410 and the guide groove 5 can drive the protective plate 47 to move. When the protective plate 47 moves, it drives the iron block 48 to move inside the moving frame 42.

[0029] like Figure 2 As shown, an L-shaped rod 411 is symmetrically integrally formed at the bottom end of the moving frame 42, a rectangular bar 412 is clamped and installed at one end of the L-shaped rod 411, a cylinder 413 is embedded and installed at the top end of the rectangular bar 412, the L-shaped rod 411 and the rectangular bar 412 have a bearing function, and by pulling the cylinder 413, the cylinder 413 drives the moving frame 42 to move through the L-shaped rod 411 and the rectangular bar 412, thereby changing the displacement difficulty of the moving frame 42, one end face of the rectangular bar 412 and one end face of the dynamic balancing machine base 1 fit each other, the highest point of the cylinder 413 is higher than the top plane of the dynamic balancing machine base 1, thereby facilitating the holding of the cylinder 413, thereby changing the holding difficulty of the cylinder 413.

[0030] Working principle: During the actual use of the device, the personnel adjust the adjustment support angle 2 of the dynamic balancing machine base 1 so that the balancing machine base 1 is placed stably on the ground. Then the personnel put the rotor into the dynamic balancing machine base 1, and then hold the cylinder 413 and pull the cylinder 413 to move. When the cylinder 413 moves, it drives the L-shaped rod 411 to move through the rectangular bar 412. When the L-shaped rod 411 moves, it drives the moving frame 42 to move inside the protective cover 41, so as to adjust the position of the moving frame 42. When the moving frame 42 moves, it drives the squeezing plate 44 to move through the spring rod 43, and squeezes the protective cover 41 through the squeezing plate 44, so that the moving frame 42 and the protective cover 41 are spaced apart. It is squeezed and fixed by the spring rod 43 and the squeezing plate 44. At the same time, the squeezing plate 44 is driven by the moving frame 42 when it moves, and the squeezing plate 44 drives the positioning column 410 to move inside the guide groove 5 when it moves. At this time, the squeezing plate 44 is displaced along the direction of the guide groove 5. The displacement of the squeezing plate 44 drives the iron block 48 and the second magnet 49 to separate, and then it is fitted and fixed with the first magnet 46 when it moves, and the two squeezing plates 44 are overlapped with each other, so as to achieve the purpose of protecting the rotor placed inside the dynamic balancing machine base 1. Then the dynamic balancing machine base 1 is started, and the rotor is detected when the dynamic balancing machine base 1 is running, and the data during the detection process is displayed on the display 3.

[0031] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
