Two symmetrical first flip plates 4027 and second flip plates 4028 are fixedly installed on both sides of the two circular fixed cylinders 4026, respectively. Each first flip plate 4027 is symmetrical with the second flip plate 4028, and each second flip plate 4028 is located above the special-shaped positioning rod 4022. The transmission unit 200 includes a driving component, which is used to drive the rotating rod 4023 to rotate. The fixed plate 2031 is driven to move by the driving assembly. When the moving plate 401 moves, it will be able to move vertically upward with the assistance of the guide block 403 and the third slide groove 4011 and the third slider 4012 in the third sliding mechanism.

When the circular fixed cylinder 4026 rotates, it can drive the second flip plate 4028 to rotate. Therefore, the second flip plate 4028 can be pressed on the special-shaped positioning rod 4022, so that the special-shaped positioning rod 4022 can limit the placed high-speed motor body 104.

[0036] like Figure 2 and Figures 4 to 5As shown, in a specific embodiment, the drive assembly includes a servo motor 201, the servo motor 201 is mounted on a side wall of the mounting base 101, a first threaded rod 2011 is fixedly mounted on the output end of the servo motor 201, the first threaded rod 2011 movably penetrates the mounting base 101, a second threaded rod 2012 is fixedly mounted on one end of the first threaded rod 2011 away from the servo motor 201, and one end of the second threaded rod 2012 away from the first threaded rod 2011 is rotatably connected to the inner cavity side wall of the mounting base 101, the first threaded rod 2011 and the second threaded rod 2012 have opposite screw directions, and the first threaded rod 2011 and the second threaded rod 2012 are respectively meshed with a first threaded sleeve 2013 and a second threaded sleeve 2014, and the first threaded sleeve 2013 and the second threaded sleeve 2014 are symmetrical to each other.

In this arrangement, it is ensured that when the servo motor 201 is running, the first threaded rod 2011 and the second threaded rod 2012 can be driven to rotate, because the first threaded rod 2011 and the second threaded rod 2012 have opposite screw directions, so when the first threaded rod 2011 and the second threaded rod 2012 rotate, the first threaded sleeve 2013 and the second threaded sleeve 2014 can be driven to move relative or oppositely in the horizontal direction with the assistance of the first slide groove 2015 and the first slider 2016 in the first sliding mechanism.

[0038] Embodiment 2:

[0039] The difference between the above embodiment and this embodiment is that: Figures 4 to 5As shown, a refrigerant lubricated rolling bearing high-speed motor test system, the two opposite side walls of the inner cavity of the mounting base 101 are fixedly installed with guide rods 202, the two guide rods 202 are symmetrical to each other, the opposite ends of the two guide rods 202 are respectively fixedly installed with limit rings 2022, the two guide rods 202 are slidably installed with guide sleeves 2021, the two guide sleeves 2021 are symmetrical to each other, and the two sides of the two guide sleeves 2021 are respectively movably installed with movable rods 2017, each movable rod 2017 is symmetrical to each other, and each movable rod 2017 is respectively movably connected to the first threaded sleeve 2013 and the second threaded sleeve 2014.

[0040] like Figures 1 to 7 As shown, in a specific embodiment, a fixing rod 203 is fixedly installed above the two guide sleeves 2021, and the two fixing rods 203 are respectively movable and penetrate the second rectangular slot 1012, and the two fixing rods 203 are symmetrical to each other, and the two fixing rods 203 are respectively movable and penetrate the second rectangular slot 1012, and a fixing plate 2031 is fixed above the two fixing rods 203, and the two fixing plates 2031 are symmetrical to each other. In this setting, when the fixing rod 203 moves horizontally, it can drive the fixing plate 2031 to move horizontally, so the movement of the fixing plate 2031 can clamp both sides of the placed high-speed motor body 104.

[0041] like Figures 1 to 7 As shown, further, a second sliding mechanism is provided on one side wall opposite to the two fixed plates 2031, and the second sliding mechanism includes two second sliding grooves 2033, and the two second sliding grooves 2033 are respectively opened on one side wall opposite to the two fixed plates 2031, and the two second sliding grooves 2033 are symmetrical to each other, and four second sliding blocks 2034 that are symmetrical to each other are slidably installed in the inner cavities of the two second sliding grooves 2033, and each second sliding block 2034 is fixedly installed with a wedge-shaped clamping block 2036 between each two, and the four wedge-shaped clamping blocks 2036 are symmetrical to each other, and the inner walls of the two second sliding grooves 2033 are fixedly installed with a first return spring 2035, and the other ends of the four first return springs 2035 are respectively fixedly connected to the side walls of the second sliding block 2034. In this setting, the installation position and components of the second sliding mechanism are determined to ensure that when the wedge-shaped clamping block 2036 contacts the high-speed motor body 104, the wedge-shaped clamping block 2036 can move to both sides, thereby limiting the corners of the high-speed motor body 104 through the wedge-shaped clamping block 2036.

[0042] like Figures 1 to 7 As shown, further, a third sliding mechanism is provided on one side wall opposite to the two fixed plates 2031, and the third sliding mechanism includes two third slide grooves 4011, which are respectively provided on one side wall opposite to the two fixed plates 2031, and the two third slide grooves 4011 are symmetrical to each other, and a third slider 4012 is slidably installed in the inner cavity of the two third slide grooves 4011, and the two third sliders 4012 are symmetrical to each other, and the opposite ends of the two third sliders 4012 are fixedly connected to the moving plate 401, and a second return spring 4016 is fixedly installed above the inner cavity of the two third slide grooves 4011, and the other ends of the two second return springs 4016 are respectively fixedly connected to the third slider 4012. In this configuration, the installation position and components of the third sliding mechanism are determined.

[0043] like Figures 1 to 7 As shown, further, a moving rod 4013 is fixedly installed on the top of the two moving plates 401, the two moving rods 4013 are symmetrical to each other, the two moving rods 4013 are movable through the two mounting plates 2032 respectively, and a driving plate 4014 and a positioning plate 4015 are fixed on the opposite side walls of the two moving rods 4013 respectively, the two driving plates 4014 and the positioning plates 4015 are symmetrical to each other, and the two driving plates 4014 and the positioning plates 4015 cooperate with the first flip plate 4027 and the second flip plate 4028 respectively. In this arrangement, it is ensured that when the moving rod 4013 moves vertically upward, it will be able to drive the driving plate 4014 and the positioning plate 4015 to move vertically upward. Therefore, the driving plate 4014 can drive the first flip plate 4027 to drive the circular fixed cylinder 4026 and the rotating rod 4023 to rotate. When the circular fixed cylinder 4026 rotates, it can drive the second flip plate 4028 to rotate. Therefore, the second flip plate 4028 can be pressed on the special-shaped positioning rod 4022, so that the special-shaped positioning rod 4022 can limit the placed high-speed motor body 104.

[0044] Embodiment 3:

[0045] The difference between the above embodiment and this embodiment is that: Figures 1 to 7 As shown, a refrigerant lubricated rolling bearing high-speed motor test system, four guide blocks 403 are fixedly installed on the mounting base 101, the four guide blocks 403 are symmetrical to each other, the four guide blocks 403 are respectively slidably connected to the moving plate 401, and the four guide blocks 403 are trapezoidal. In this setting, the installation position and components of the guide blocks 403 are determined, ensuring that when the moving plate 401 moves horizontally, it can move horizontally and vertically when it contacts the guide blocks 403.

[0046] like Figures 1 to 4As shown, in a specific embodiment, two symmetrical torsion springs 4025 are disposed on the two rotating rods 4023, and the two ends of each torsion spring 4025 are disposed on a side wall opposite to the bearing 4024 and the circular fixed cylinder 4026. In this arrangement, it is ensured that the rotating rod 4023 can be reset with the assistance of the torsion spring 4025.

[0047] The implementation principle of a refrigerant lubricated rolling bearing high-speed motor test system of this embodiment is as follows:

[0048] First, the staff places the high-speed motor body 104 on the placement plate 1021. When the placement is completed, the staff controls the servo motor 201 to operate. When the servo motor 201 operates, it can drive the first threaded rod 2011 and the second threaded rod 2012 to rotate. Because the first threaded rod 2011 and the second threaded rod 2012 have opposite screw directions, when the first threaded rod 2011 and the second threaded rod 2012 rotate, they can drive the first threaded sleeve 2013 and the second threaded sleeve 2014 to move relative to or oppositely in the horizontal direction with the assistance of the first slide groove 2015 and the first slider 2016 in the first sliding mechanism.

[0049] When the first threaded sleeve 2013 and the second threaded sleeve 2014 move in opposite directions, the guide sleeve 2021 can be pulled by the movable rod 2017 to move horizontally with the assistance of the guide rod 202. When the guide sleeve 2021 moves, it can drive the fixed rod 203 to move horizontally. When the fixed rod 203 moves horizontally, it can drive the fixed plate 2031 to move horizontally. Therefore, the movement of the fixed plate 2031 can clamp the two sides of the placed high-speed motor body 104. Because the fixed plate 2031 is slidably provided with a wedge-shaped clamping block 2036, when the wedge-shaped clamping block 2036 contacts the high-speed motor body 104, the wedge-shaped clamping block 2036 can be moved to both sides, so that the corner of the high-speed motor body 104 can be limited by the wedge-shaped clamping block 2036.

[0050] At the same time, when the fixed plate 2031 moves horizontally relative to each other, the fixed plate 2031 will be able to drive the moving plate 401 to move horizontally. When the moving plate 401 moves, it will be able to move vertically upward with the assistance of the guide block 403 and the third slide groove 4011 and the third slider 4012 in the third sliding mechanism. When the moving plate 401 moves vertically upward, it will be able to drive the moving rod 4013 to move vertically upward. When the moving rod 4013 moves vertically upward, it will be able to drive the driving plate 4014 and the positioning plate 4015 to move vertically upward. Therefore, the first flip plate 4027 can be driven by the driving plate 4014 to drive the circular fixed cylinder 4026 and the rotating rod 4023 to rotate. When the circular fixed cylinder 4026 rotates, it can drive the second flip plate 4028 to rotate. Therefore, the second flip plate 4028 can be pressed on the special-shaped positioning rod 4022, so that the special-shaped positioning rod 4022 can limit the placed high-speed motor body 104;

[0051] When the high-speed motor body 104 is positioned, the staff connects the pipe provided on the refrigerant storage tank 103 and the bearing provided on the high-speed motor body 104, thereby delivering the liquid through the refrigerant pump, and then starts the high-speed motor body 104 for testing.
