[0036] In the above embodiment, the specific structural composition design of the positioning component 4 effectively realizes the fixed clamping of the motor, so that the motor can avoid displacement during the vibration test and prevent the test data from being affected, further improving the accuracy of the data and achieving good use effect.

[0037] In at least one embodiment of the present application, reference Figure 1 , the motor vibration test device also includes an isolation component 5. The isolation component 5 is arranged on the inner side of the positioning component 4. The isolation component 5 is configured to isolate the motor to be tested and position the motor to be tested during the test. The positioning component 4 is also configured to position and fix the isolation component 5 with the motor to be tested during the test. In this way, by adding the isolation component 5 on the inner side of the positioning component 4, the isolation component 5 is used to isolate the motor to be tested and position the motor to be tested during the test, thereby effectively achieving full blocking of the motor to be tested and the overall part of the vibration test device, so that the vibration generated by the motor to be tested during the test will not be transmitted, reducing the vibration loss generated when the motor to be tested vibrates, further improving the accuracy of the data, and achieving good use effect.

[0039] In the above embodiment, by designing the specific structural composition of the isolation component 5, it is effectively achieved that the motor to be tested and the overall part of the vibration testing device are fully blocked, so that the vibration generated by the motor to be tested during the test will not be transmitted, the vibration loss generated when the motor to be tested vibrates is reduced, the accuracy of the data is further improved, and the use effect is good.

[0040] The working principle of the motor vibration testing device is described below with examples in conjunction with specific implementations.

[0041] Turn on the first forward and reverse motor 31, and one end of the output shaft of the first forward and reverse motor 31 drives the driving threaded rod 32 to rotate. The outer wall of the driving threaded rod 32 is threadedly connected with the inner wall of the first threaded ring 33. When the driving threaded rod 32 rotates, the first threaded ring 33 is driven to move on the outer wall of the driving threaded rod 32. When the driving threaded rod 32 is displaced, the first connecting rod 34 is driven to slide on the inner wall of the first stroke groove set on the top surface of the workbench 1. When the first connecting rod 34 is displaced, the bottom plate 35 is driven to move on the top surface of the workbench 1. The slider 36 set at the bottom of the bottom plate 35 slides on the inner wall of the slide groove set on the top surface of the workbench 1. The bottom plate 35 drives the bracket 37 to move. The displacement of the bracket 37 At the same time, the driven ring 39 is driven to move, and the driven ring 39 drives the vibration detection module 310 to move horizontally, and then the second forward and reverse motor 38 is started. One end of the output shaft of the second forward and reverse motor 38 drives the driving wheel 311 to rotate. The driving wheel 311 rotates through the transmission belt 312 and drives the driven ring 39 to rotate on the inner wall of the bracket 37. The driven ring 39 rotates and drives the vibration detection module 310 to rotate, so that the vibration detection module 310 rotates 365 degrees around the body of the motor to be tested without dead angles. The vibration detection module 310 can be controlled to move to any position of the motor body to be tested by adjusting the rotation direction and number of rotations of the first forward and reverse motor 31 and the second forward and reverse motor 38.

[0042] First, rotate the turntable 41. When the turntable 41 rotates, the driving rod 49 is driven to rotate. When the driving rod 49 rotates, the forward threaded rod 42 is driven to rotate. The forward threaded rod 42 drives the long rod 43 to rotate. The long rod 43 synchronously drives the reverse threaded rod 44 to rotate. The outer walls of the forward threaded rod 42 and the reverse threaded rod 44 are both threadedly mounted with a second threaded ring 45. When the forward threaded rod 42 and the reverse threaded rod 44 rotate, the second threaded ring 45 is driven to slide on the outer walls of the forward threaded rod 42 and the reverse threaded rod 44. When the second threaded ring 45 is displaced, it drives the second connecting rod 48 to slide on the inner wall of the second stroke groove set on the top surface of the workbench 1. The second connecting rod 48 drives the connecting block 46 set on its top The connecting block 46 drives the first clamping block 47 to move on the top surface of the workbench 1. Since the thread arranged on the outer wall of the forward threaded rod 42 is opposite to the thread arranged on the outer wall of the reverse threaded rod 44, the first clamping block 47 arranged on the forward threaded rod 42 and the first clamping block 47 arranged on the reverse threaded rod 44 are displaced toward each other, so that the first clamping block 47 arranged on the forward threaded rod 42 and the first clamping block 47 arranged on the reverse threaded rod 44 are unfolded, and then the tail of the motor to be tested is placed at the center of the first clamping block 47, and the turntable 41 is rotated in the reverse direction. Similarly, the first clamping block 47 arranged on the forward threaded rod 42 and the first clamping block 47 arranged on the reverse threaded rod 44 can be reset, so that the motor to be tested can be positioned and clamped.

[0043] When the first clamping block 47 provided on the forward threaded rod 42 and the first clamping block 47 provided on the reverse threaded rod 44 are reset, the first clamping block 47 drives the first telescopic rod 54 to move, the first telescopic rod 54 drives the second clamping block 51 to move, the second clamping block 51 synchronously drives the rubber plate 52 to move, the second clamping block 51 provided with the rubber plate 52 clamps the tail of the motor to be tested, when the second clamping block 51 clamps the tail of the motor to be tested, the tail of the motor to be tested will reversely squeeze the second clamping block 51, so that the second clamping block 51 will be displaced a short distance, at this time the second clamping block 51 will squeeze the first spring 53, so that the first spring 53 is compressed , and the first telescopic rod is in a retracted state, but the first spring 53 is not completely compressed. Before placing the tail of the motor to be tested at the center of the first clamping block 47, the output shaft of the motor to be tested is first inserted into the rotating ring 56. The clamping plate 57 arranged on the inner wall of the rotating ring 56 is squeezed, causing the clamping plate 57 to move. When the clamping plate 57 moves, the second spring 59 is compressed to form a compressed state. At the same time, the second telescopic rod 58 is in a retracted state, but the second spring 59 is not completely compressed. When the motor to be tested is started for vibration test, its output shaft will drive the rotating ring 56 to drive the inner wall of the mounting frame 55 to rotate through the clamping plate 57 and the second telescopic rod 58.
