[0032] like Figures 1 to 4 As shown, the utility model provides a motor noise detection device.

[0033] Specifically, by Figure 1-4 Given, including:

[0034] Loading plate 1 and motor body 9;

[0035] A connector 12 for providing power to the motor body 9;

[0036] A noise detector 16 for detecting noise;

[0037] A fixing assembly for fixing the motor;

[0038] It is characterized in that the fixing assembly includes a slide plate 7 arranged on the top surface of the loading plate 1, a rubber placement groove 8 fixedly installed on the top of the slide plate 7, a vertical plate 11 and a load tooling 3 installed on the top of the slide plate 7, a pressure plate 10 hinged on the top of the vertical plate 11, and a rotatable connector 12 installed on the front end of the load tooling 3.

[0039] In the utility model, a rubber placement groove 8 is used to place the motor body 9 therein, and then the motor body 9 is connected to the connector 12. After the connection, the pressure plate 10 is rotated to make the pressure plate 10 fit onto the top surface of the motor body 9, and the motor body 9 is fixed so that it is not easy to have problems during the subsequent detection process. After fixation, the start-stop switch 6 is pressed to make the load tooling 3 drive the motor body 9 to perform load operation. At this time, the user can listen at a distance of eighty to one hundred and twenty centimeters from the motor to distinguish whether there is an abnormal sound in the motor at this time, and complete the preliminary detection.

[0040] After the preliminary inspection is completed, press the start-stop switch 6 again to put the motor body 9 into a no-load state. At this time, push the pull rod 17 to make the sealing plate 4 fit the barrier box 2, so that the motor body 9 is sent into the barrier box 2 and is sealed by the sealing plate 4 and the barrier box 2. Then observe the specific value on the display screen 13. If it exceeds the established threshold, the display screen 13 will emit red light and display the value, and the buzzer 14 will sound. If qualified, the display screen 13 will always remain in the green state. After this step, the entire detection process can be completed.

[0041] By setting up a fixing component, the motor body 9 will not produce excessive resonance with the surrounding components when being tested. Even if resonance occurs, due to the material of the parts in the fixing component, it will not generate excessive noise and will hardly affect the detection, thereby improving the quality and accuracy of the detection.

[0042] Furthermore, as a specific implementation of the present utility model, the present utility model provides a motor noise detection device.

[0043] Specifically, Figure 1-4As shown, it also includes an isolation component, which includes a barrier box 2 fixedly installed on the top surface of the loading plate 1, a sealing plate 4 fixedly installed on one side of the slide plate 7, a plurality of sealing strips 5 installed on the inner wall of the sealing plate 4, a plurality of docking grooves 15 opened on the side wall of the barrier box 2, and a sound insulation cotton block 19 fixedly installed between the sealing plate 4 and the inner wall of the barrier box 2.

[0044] In the utility model, by providing an isolation component, the interference of the external environment on the noise detector 16 is reduced after the motor body 9 enters the barrier box 2, so that the noise detector 16 can detect the motor body 9 more accurately, and also improve the accuracy of the device's detection of the noise of the motor body 9. During the process, the sealing strip 5 and the docking groove 15 fit together to make the barrier box 2 in a nearly sealed state. The sound insulation cotton block 19 installed in the barrier box 2 and the sealing plate 4 can help the noise detector 16 to isolate most of the noise, thereby improving the detection quality.

[0045] Furthermore, as a specific implementation of the present utility model, the present utility model provides a motor noise detection device.

[0046] Specifically, Figure 1 As shown, a start-stop switch 6 is provided on the top surface of the load fixture 3 .

[0048] Furthermore, as a specific implementation of the present utility model, the present utility model provides a motor noise detection device.

[0049] Specifically, Figure 1 As shown, the material of the pressing plate 10 is rubber.

[0050] In the utility model, in order to reduce the noise generated by the resonance between the pressing plate 10 and the motor body 9, the detection quality is improved.

[0051] Furthermore, as a specific implementation of the present utility model, the present utility model provides a motor noise detection device.

[0052] Specifically, Figure 2 and Figure 4 As shown, a slide groove 18 is provided in the middle of the top surface of the loading plate 1 , and the sealing plate 4 and the sliding plate 7 can be slidably installed in the slide groove 18 .

[0053] In the utility model, in order to limit and guide the sealing plate 4 and the sliding plate 7 during the movement, the sealing plate 4 and the sliding plate 7 will not be easily deflected during the movement.

[0054] Furthermore, as a specific implementation of the present utility model, the present utility model provides a motor noise detection device.

[0055] Specifically, Figure 1 , Figure 3 , Figure 4 As shown, a display screen 13 is installed above the barrier box 2 , and a buzzer 14 is provided above the barrier box 2 on one side of the display screen 13 . The buzzer 14 and the display screen 13 are both electrically connected to a noise detector 16 .

[0056] In the present invention, in order to enable the user to observe the detection result more clearly, when the noise detector 16 detects that the noise exceeds a predetermined threshold, the buzzer 14 and the display screen 13 are activated, the buzzer 14 sounds and the display screen 13 displays the specific value in red, so that the user can observe this phenomenon in time and deal with it in time.

[0057] Furthermore, as a specific implementation of the present utility model, the present utility model provides a motor noise detection device.

[0058] Specifically, Figure 1 and Figure 4 As shown, the plurality of sealing strips 5 are respectively matched with the plurality of docking grooves 15 , and a pull rod 17 is fixedly mounted on one side of the sealing plate 4 .

[0059] In the present invention, in order to make the sealing performance of the sealing plate 4 better after being attached to the barrier box 2 and effectively reduce the interference of the external environment, the pull rod 17 is provided to make the movement of the sealing plate 4 and the slide plate 7 more convenient.

[0060] Working principle: Use the rubber placement groove 8 to place the motor body 9 in it, and then connect the motor body 9 to the connector 12. After the connection, rotate the pressure plate 10 to make the pressure plate 10 fit onto the top surface of the motor body 9, and fix the motor body 9 so that it is not easy to have problems during the subsequent detection process. After fixing, press the start-stop switch 6 to make the load tooling 3 drive the motor body 9 to perform load operation. At this time, the user can listen at a distance of 80 to 120 centimeters from the motor to distinguish whether there is any abnormal sound in the motor at this time, and complete the preliminary detection.

[0061] After the preliminary inspection is completed, press the start-stop switch 6 again to put the motor body 9 into a no-load state. At this time, push the pull rod 17 to make the sealing plate 4 fit the barrier box 2, so that the motor body 9 is sent into the barrier box 2 and is sealed by the sealing plate 4 and the barrier box 2. Then observe the specific value on the display screen 13. If it exceeds the established threshold, the display screen 13 will emit red light and display the value, and the buzzer 14 will sound. If qualified, the display screen 13 will always remain in the green state. After this step, the entire detection process can be completed.

[0062] By setting up a fixing component, the motor body 9 will not produce excessive resonance with the surrounding components when being tested. Even if resonance occurs, due to the material of the parts in the fixing component, it will not generate excessive noise and will hardly affect the detection, thereby improving the quality and accuracy of the detection.

[0063] By providing an isolation component, the external environment interference to the noise detector 16 is reduced after the motor body 9 enters the barrier box 2, making the noise detector 16 more accurate in detecting the motor body 9. The accuracy of the device in detecting the noise of the motor body 9 is also improved. During the process, the sealing strip 5 and the docking groove 15 fit together to make the barrier box 2 in a nearly sealed state. The sound insulation cotton blocks 19 installed in the barrier box 2 and the sealing plate 4 can help the noise detector 16 isolate most of the noise, thereby improving the detection quality.
