However, during the detection process, the device may generate vibration due to excessive speed, thereby affecting the accuracy of subsequent test results. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a speed detection platform for a motor, which solves the problems raised in the above background technology. To achieve the above purpose, the utility model is implemented through the following technical solutions: a speed detection platform for a motor, including a detection platform body, a motor to be tested is mounted on the side of the detection platform body, and an output shaft is connected to the side of the motor to be tested;

[0006] A shock absorbing assembly is arranged inside the detection platform body, and the shock absorbing assembly includes a shock absorbing chamber, the inner wall of the shock absorbing chamber is fixedly connected with a spring 1, the top of the spring 1 is fixedly connected with a shock absorbing rod, the top of the shock absorbing rod is fixedly connected with a force-bearing arc rod, and the inner wall of the shock absorbing chamber is fixedly connected with a rubber block.

[0007] Preferably, the rubber blocks are arranged in three groups, each group of the rubber blocks is arranged in three groups, and the rubber blocks are distributed in a circular array about the shock absorbing rod.

[0008] Preferably, the stressed arc-shaped rod is located at the bottom of the output shaft, and the stressed arc-shaped rod and the output shaft are in contact with each other.

[0009] Preferably, an auxiliary component is provided at the bottom of the detection platform body, and the auxiliary component includes an oil tank, the top of the oil tank is slidably connected to a force-bearing rod, the bottom of the force-bearing rod is fixedly connected to a spring 2, and the outer side of the oil tank is fixedly connected to an elastic liquid bag.

[0012] The utility model provides a speed detection platform for a motor, which has the following beneficial effects:

[0013] (1) When the output shaft of the motor vibrates due to high-speed rotation, the speed detection platform can squeeze the arc-shaped rod, causing the shock-absorbing rod to move. The shock-absorbing rod then squeezes the spring and moves in the shock-absorbing chamber. At this time, the shock-absorbing rod is violently squeezed by the rubber block, reducing the vibration amplitude and vibration frequency of the shock-absorbing rod, thereby damping the output shaft and improving the accuracy of subsequent detection results.

[0014] (2) When the output shaft of the motor vibrates too violently, the shock-absorbing rod squeezes the force-bearing rod, and the force-bearing rod then squeezes the second spring to move. Since the force-bearing rod is slidably connected to the oil tank, the oil in the oil tank moves into the elastic liquid bag, causing the elastic liquid bag to expand. In this way, the force in the oil tank is slowly transmitted to perform secondary shock absorption, further improving the accuracy of subsequent detection results. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0024] See also Figure 1-Figure 4 A speed detection platform for a motor includes a detection platform body 100, a motor to be tested 200 is mounted on the side of the detection platform body 100, and an output shaft 300 is transmission-connected to the side of the motor to be tested 200;

[0025] A shock absorbing assembly 400 is arranged inside the detection platform body 100, and the shock absorbing assembly 400 includes a shock absorbing chamber 401, the inner wall of the shock absorbing chamber 401 is fixedly connected with a spring 1 402, the top of the spring 1 402 is fixedly connected with a shock absorbing rod 403, the top of the shock absorbing rod 403 is fixedly connected with a force-bearing arc rod 404, the force-bearing arc rod 404 is located at the bottom of the output shaft 300, and the force-bearing arc rod 404 and the output shaft 300 are in contact with each other. When the output shaft 300 vibrates due to high-speed rotation, the force-bearing arc rod 404 can be squeezed, so that the shock absorbing rod 403 fixedly connected to the force-bearing arc rod 404 moves, and the shock absorbing rod 403 then squeezes the spring 1 402 fixedly connected thereto and moves in the shock absorbing chamber 401. The inner wall of the shock absorbing chamber 401 is fixedly connected with a rubber block 405, and three groups of rubber blocks 405 are provided, each group of rubber blocks 405 is provided with three rubber blocks, and the rubber blocks 405 are distributed in a circular array about the shock absorbing rod 403. When the shock absorbing rod 403 moves in the shock absorbing chamber 401, the shock absorbing rod 403 is violently squeezed by the rubber block 405 fixedly connected to the shock absorbing chamber 401, and the vibration amplitude and vibration frequency of the shock absorbing rod 403 are reduced, thereby damping the output shaft 300 and improving the accuracy of subsequent detection results.

[0026] During use, when the output shaft 300 vibrates due to high-speed rotation, the stressed arc rod 404 can be squeezed, so that the shock-absorbing rod 403 fixedly connected to the stressed arc rod 404 moves, and the shock-absorbing rod 403 then squeezes the spring 1 402 fixedly connected to it and moves in the shock-absorbing chamber 401. At this time, the shock-absorbing rod 403 is violently squeezed by the rubber block 405 fixedly connected to the shock-absorbing chamber 401, reducing the vibration amplitude and vibration frequency of the shock-absorbing rod 403, thereby reducing the shock of the output shaft 300. Example

[0027] See also Figure 1-Figure 4On the basis of the first embodiment, an auxiliary component 500 is provided at the bottom of the detection platform body 100, and the auxiliary component 500 includes an oil tank 501, and a force rod 502 is slidably connected to the top of the oil tank 501. The shock absorber tank 401 and the detection platform body 100 are both provided with a through opening, and the cross-sectional shape of the opening is adapted to the force rod 502. A spring 2 503 is fixedly connected to the bottom of the force rod 502, and one end of the spring 2 503 is away from the force rod 502 and is fixedly connected to the oil tank 501. When the vibration of the output shaft 300 is too severe, the shock absorber rod 403 squeezes the force rod 502, and the force rod 502 then squeezes the spring 2 503 fixedly connected thereto to move. An elastic liquid capsule 504 is fixedly connected to the outside of the oil tank 501. When the force-bearing rod 502 moves, due to the sliding connection between the force-bearing rod 502 and the oil tank 501, the oil in the oil tank 501 moves into the elastic liquid bag 504, causing the elastic liquid bag 504 to expand, thereby utilizing the characteristic of the slow transmission of the force in the oil tank 501 to perform secondary shock absorption, further improving the accuracy of subsequent detection results.

[0028] During use, on the basis of Example 1, when the vibration of the output shaft 300 is too severe, the shock-absorbing rod 403 squeezes the force-bearing rod 502, and the force-bearing rod 502 then squeezes the spring 2 503 fixedly connected thereto and moves. Since the force-bearing rod 502 is slidingly connected to the oil tank 501, the oil in the oil tank 501 moves into the elastic liquid bag 504, causing the elastic liquid bag 504 to expand, thereby utilizing the characteristic that the force in the oil tank 501 is slowly transmitted to perform secondary shock absorption.
