[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the motor testing device provided in the embodiment of the present application comprises a mounting frame 1, a rotating plate 2, a silent room 3 provided with an inlet silencer channel and an outlet silencer channel, a conveyor line 4 respectively passing through the inlet silencer channel and the outlet silencer channel at both ends, a divider 5 arranged on the mounting frame 1 for driving the rotating plate 2 to rotate, a load testing mechanism 6 arranged at both ends of the rotating plate 2, and a decibel testing mechanism 7 arranged on a frame 41, wherein the mounting frame 1 is arranged in the silent room 3, and the decibel testing mechanism 7 is used to test the noise of the motor in one of the load testing mechanisms 6 when it is idling, and when the decibel testing mechanism 7 corresponds to one of the load testing mechanisms 6, the other load testing mechanism 6 corresponds to the top of the conveyor line 4.

[0019] In actual use, the motor to be tested is transported to the silent room 3 via the conveyor line 4, and then the motor to be tested on the conveyor line 4 is transferred to one of the load test mechanisms 6. The load test mechanism 6 then works to collect current, voltage, and speed to determine whether the current exceeds the rated value. Then the indexer 5 drives the load test mechanism 6 on which the motor to be tested is placed to stop the load, and under the drive of the indexer 5, it rotates with the rotating plate 2 to the corresponding position of the decibel test mechanism 7, and the decibel test mechanism 7 is used to test whether the motor running noise is abnormal under no-load. At this time, another load test mechanism 6 receives the motor to be tested in the conveyor line 4.

[0020] In the above design, the motor can be load tested to detect the load force of the motor, and the running noise of the motor under no-load can be detected. The whole device occupies a small space and the whole operation process is compact, which can effectively improve work efficiency.

[0021] Specifically: Figure 2 As shown, the load testing mechanism 6 includes a torsional magnetic powder clutch 61 disposed on the rotating plate 2 for providing load, and an encoder 62 disposed on the rotating plate 2 and electrically connected to the torsional magnetic powder clutch 61 for measuring the motor speed under load.

[0022] In actual use, when the motor to be tested is subjected to a load test, a set load is applied to the motor to be tested through the torque magnetic powder clutch 61, and the current, voltage and speed are collected through the encoder 62 to determine whether the current exceeds the rated value.

[0023] In the above design, the structural design and specific implementation method of the load testing mechanism 6 can effectively realize a fast and accurate load test on the motor to be tested.

[0024] Specifically: Figure 2 and Figure 3 As shown, the decibel testing mechanism 7 includes a linear module 71 vertically arranged on the mounting frame 1, a sound-absorbing box 72 arranged at the output end of the linear module 71, and a decibel pickup 73 arranged at the upper end of the sound-absorbing box 72. The lower end of the sound-absorbing box 72 is provided with an opening for allowing the load testing mechanism 6 to extend into the sound-absorbing box 72.

[0025] In actual use, when the decibel test is not performed, the soundproof box 72 is located in the area above the load testing mechanism 6. When the load testing mechanism 6 rotates to below the opening, the soundproof box 72 is driven downward by the linear module 71, so that the motor to be tested in the load testing mechanism 6 extends into the soundproof box 72, and the decibel value of the motor when it is no-load is detected by the decibel pickup 73.

[0026] In the above design, the decibel test mechanism 7 can effectively detect the decibel value of the motor under test when it is running at no load, and when performing the decibel test, another load test mechanism 6 can also be loaded and unloaded, which effectively improves the work efficiency.

[0027] Specifically: Figure 4 As shown, the conveyor line 4 includes a frame 41, a driving roller arranged at one end of the frame 41, a driven roller arranged at the other end of the frame 41, a conveyor belt 42 wound around the driving roller and the driven roller, and a motor 43 arranged on the frame 41 for driving the driving roller to rotate.

[0028] In actual use, the active roller is driven to rotate by the No. 1 motor 43, and the conveyor belt 42 is driven to transmit with the cooperation of the driven roller.

[0029] In the above design, the structural design and specific implementation method of the conveyor line 4 can effectively realize the stable and rapid conveyance of the motor to be tested.

[0030] Specifically: Figure 3 As shown, a safety grating 8 is also provided on the side of the mounting frame 1 close to the conveyor line 4 .

[0031] In actual use, when the load testing mechanism 6 is loading and unloading materials, when the person in charge of loading and unloading materials passes the motor through the safety grating 8, the control mechanism receives the signal of the safety grating 8 and controls the indexer 5 to stop rotating.

[0032] The above design can effectively improve the safety of the operation process.

[0033] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
