The inner wall of each transition box 6 is rotatably connected with a rotating wheel 14. When the water drawn out from the drainage pipe 52 contacts the rotating wheel 14, the rotating wheel 14 will rotate due to the action of gravity, and the water can be sprinkled onto the inner wall of the transition box 6.

[0043] The inner wall of each transition box 6 is fixedly connected with a water dividing plate 13, which can allow water to enter the interior of the transition box 6 more evenly. The inner wall of each transition box 6 is fixedly connected with convex strips 15 in a circumferential array, which can increase the contact area between water and the transition box 6 and fully dissipate the heat.

[0044] A cooling mechanism 8 is provided below the middle housing 2 of the motor, and the cooling mechanism 8 includes a water collecting tank 81 and a transfer tank 82. The water containing heat first enters the interior of the transfer tank 82, and one end of each drainage pipe 52 away from the water pump 51 is connected to the interior of the transition box 6, so as to facilitate the drainage of water to the interior of the transition box 6, and one end of each pumping pipe 2 72 away from the water pump 2 71 is connected to the interior of the water collecting tank 81.

[0046] The interior of the motor head housing 1 is provided with a transmission mechanism 9 in a circular array. The inner wall of the motor head housing 1 is rotatably connected with a rotating shaft 10, and the rotating shaft 10 is connected to the internal structure of the motor body. When the motor is turned on, it can drive the rotating shaft 10 to rotate. The outer surface of the rotating shaft 10 located inside the motor head housing 1 is fixedly connected with a bevel gear 11.

[0047] The transmission mechanism 9 includes a fixed block 91, which is fixedly connected to the inner wall of the motor head housing 1. The outer surface of the fixed block 91 is rotatably connected to a connecting rod 94, which penetrates the fixed block 91. The fixed block 91 can fix and support the connecting rod 94. The two ends of the fixed block 91 are respectively fixedly connected to a bevel gear 1 92 and a bevel gear 2 93. The bevel gear 2 93 is meshed with the bevel gear 4 11. When the rotating shaft 10 drives the bevel gear 4 11 to rotate, the bevel gear 4 11 can drive the bevel gear 2 93 to rotate.

[0048] The outer surface of bevel gear one 92 is meshed with bevel gear three 95. The rotation of bevel gear one 92 can drive bevel gear three 95 to rotate. The outer surface of bevel gear three 95 is fixedly connected with a through rod 96. The through rod 96 penetrates the motor head shell 1 and is rotatably connected to the motor head shell 1. The end of the through rod 96 away from the bevel gear three 95 is fixedly connected with a fan blade 97. When bevel gear three 95 rotates, it can drive the through rod 96 and the fan blade 97 to rotate, so as to blow air into the interior of the middle shell 2 of the motor, avoid dust accumulation inside the middle shell 2 of the motor, blow out dust from the mesh plate at the rear of the motor rear shell 3, and blow out heat at the same time, thereby enhancing the heat dissipation effect.

[0049] The implementation principle of a high-speed and high-precision spindle servo motor for preventing temperature rise in an embodiment of the present application is as follows: during use, when the servo motor is controlled to be turned on, the conductive metal touch plate three 26 contacts the conductive metal touch plate one 23. At this time, the heating plate 29 can be controlled to be turned on by the controller. The heating plate 29 can heat the inside of the middle shell 2 of the motor. The purpose of heating is to prevent the inside of the middle shell 2 of the motor from being damp in humid weather or places with heavy humidity, thereby affecting the normal use of the servo motor. At this time, the rotating shaft 10 will rotate. The rotation of the rotating shaft 10 can drive the fan blades 97 to rotate through the transmission of the transmission mechanism 9, which can heat the inside of the middle shell 2 of the motor. Blowing can blow out the dust inside the middle shell 2 of the motor and increase the air circulation inside the middle shell 2 of the motor. With the heating of the heating plate 29, the inside of the middle shell 2 of the motor can be dehumidified. When the servo motor runs for a certain period of time and the temperature inside the middle shell 2 of the motor reaches a certain height, the water inside the surrounding tube 4 and the temperature inside the middle shell 2 of the motor will be conducted to the inside of the containing tube 22 through the heat conducting rod 21, thereby heating the pure water inside the containing tube 22. After the pure water is heated, its volume will greatly expand. After the expansion of the pure water, it will push the conductive metal touch plate 3 26 up. The rise of the conductive metal touch plate 3 26 can drive the conductive metal The touch plate 4 27 rises, and the conductive metal touch plate 4 27 rises and can contact the conductive metal touch plate 2 25, thereby separating the conductive metal touch plate 3 26 from the conductive metal touch plate 1 23, turning off the heating plate 29, and at the same time connecting the conductive metal touch plate 25 with the conductive metal touch plate 4 27, controlling the water pump 1 51 and the water pump 2 71 to start, and the water pump 2 71 can be turned on to pump cooling water into the interior of the surrounding pipe 4. When the cooling water passes through the interior of the surrounding pipe 4, it can take out the heat inside the motor middle housing 2, thereby playing a role in rapid heat dissipation. The water pump 1 51 extracts the water carrying heat inside the surrounding pipe 4 into the interior of the transition box 6, carrying The heated water drives the rotating wheel 14 to rotate due to gravity, and the heated water is sprinkled onto the inner wall of the transition box 6. The heat can be conducted through the heat-conducting strips 12 installed on the transition box 6 to further increase the heat dissipation. Then the water is discharged from the transition box 6 into the interior of the transfer box 82, and after being cooled by the heat exchanger 84, it enters the interior of the water collecting tank 81, and is pumped to the interior of the surround pipe 4 through the water pump 2 71 again, thereby having a good heat dissipation and cooling effect on the interior of the middle housing 2 of the motor, and can prevent the internal temperature of the middle housing 2 of the motor from being too high, causing damage to the motor body. This device can heat and moisture-proof the servo motor and can automatically cool the servo motor.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
