[0001] This utility model relates to the field of motor testing technology, specifically a multifunctional motor incoming inspection test bench. Background Technology

[0002] Motor testing simulates actual motor operation by controlling parameters such as voltage, current, and speed. It detects the heating (temperature rise) of the windings at rated output power and torque, verifying the accuracy and rationality of the motor's design and manufacturing parameters. During motor testing inside a damp heat chamber, the motor's output drives a weighted object to rotate, simulating motor operation. Changing the object requires opening the damp heat chamber, causing heat loss and increasing energy consumption for temperature adjustment. Summary of the Invention

[0007] Preferably, an angle sensor is fixedly connected to the bottom of the inner cavity of the test chamber, and the coupling body is located inside the angle sensor. The angle sensor detects the rotation angle between the test motor driving the coupling body and the hexagonal column.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1

[0021] Please refer to Figures 1 to 5. This utility model provides a technical solution: a multifunctional motor incoming inspection test bench, including a fixed platform 1, a test box 2 fixedly connected to the top of the fixed platform 1, a first electric telescopic rod 3 fixedly connected to one side of the inner cavity of the test box 2, a movable frame 4 fixedly connected to the telescopic end of the first electric telescopic rod 3, a fixed box 5 fixedly connected to one side of the movable frame 4, a rotating shaft 7 rotatably connected to one side of the inner cavity of the fixed box 5, one end of the rotating shaft 7 extending to the outside of the fixed box 5 and fixedly connected to a rotating disk 19, a rotating frame 18 fixedly connected to the top of the movable frame 4, the rotating disk 19 being located inside the rotating frame 18, a plurality of drive columns 13 rotatably connected to the inside of the rotating disk 19 via bearings, one end of each drive column 13 extending to the outside of the rotating disk 19 and fixedly connected to a counterweight cylinder 14, a drive motor 6 fixedly connected to the top of the fixed box 5, the output end of the drive motor 6 extending to the inside of the fixed box 5 and fixedly connected to a worm gear 9, and a worm wheel 8, which is connected to the worm gear 9, fixedly sleeved on the outside of the rotating shaft 7.

[0022] A second electric telescopic rod 15 is fixedly connected to one side of the rotating disk 19 and to both sides of the counterweight cylinder 14. A friction block 16 is fixedly connected to the telescopic end of the second electric telescopic rod 15. A friction sleeve is provided on the outer side of the counterweight cylinder 14. When the counterweight cylinder 14 needs to be replaced, the friction block 16 is moved by the telescopic end of the second electric telescopic rod 15, so that the friction block 16 cooperates with the friction sleeve on the outer side of the counterweight cylinder 14 to limit the position of the counterweight cylinder 14. When the counterweight cylinder 14 needs to be rotated, the telescopic end of the second electric telescopic rod 15 drives the friction block 16 to reset and move, so that the friction block 16 disengages from the friction sleeve on the outer side of the counterweight cylinder 14 and releases the limit on the counterweight cylinder 14.

[0023] The bottom of the inner cavity of the test chamber 2 is fixedly connected to the test motor 10 by screws. The bottom of the inner cavity of the test chamber 2 and one side of the test motor 10 are fixedly connected to the fixing block 12. The fixing block 12 is connected to the coupling body 11 through the bearing. The coupling body 11 is a keyway coupling. The test motor 10 is connected to the coupling body 11 by the keyway in the keyway coupling cooperating with the flat key on the outside of the output end of the test motor 10. The test motor 10 is equipped with a detection unit, which is a temperature sensor and a current / voltage detector.

[0024] An angle sensor 17 is fixedly connected to the bottom of the inner cavity of the test chamber 2. The coupling body 11 is located inside the angle sensor 17. The angle sensor 17 detects the rotation angle of the coupling body 11 and the hexagonal column 20 driven by the test motor 10. When the output end of the test motor 10 drives the hexagonal column 20 to rotate to the specified angle, the test motor 10 stops working. At this time, the hexagonal column 20 is separated from the drive column 13 so that the drive column 13 and the hexagonal column 20 can be connected later. An angle sensor 17 is also installed inside the fixed box 5. The angle sensor 17 is located outside the rotating shaft 7. The angle sensor 17 can detect the rotation angle of the rotating shaft 7 so that the counterweight cylinder 14 to be used can be rotated to the working position so that the hexagonal column 20 can be connected to the hexagonal hole 21 inside the drive column 13 corresponding to the counterweight cylinder 14.

[0025] One end of each drive column 13 is provided with a hexagonal hole 21, and the other end of the angle sensor 17 is equipped with a drive shaft. One end of the drive shaft is fixedly connected to a hexagonal post 20. The hexagonal post 20 matches the hexagonal hole 21, so that the hexagonal post 20 can be inserted into the hexagonal hole 21, and the hexagonal post 20 is connected to the drive column 13 and the counterweight cylinder 14.

[0026] Example 2

[0027] Please refer to Figure 1. This utility model provides a technical solution: A three-way connector 22 is fixedly connected to the top of the test chamber 2. The bottom end of the three-way connector 22 extends into the interior of the test chamber 2 and is fixedly connected to a nozzle 23. A controller is fixedly connected to one side of the test chamber 2, and the test bench is controlled by the controller. An exhaust valve for exhausting air is installed on the back of the test chamber 2.

[0028] In summary, when using this multi-functional motor factory testing bench, the output end of the test motor 10 is connected to the coupling body 11. The test motor 10 can then be fixed to the bottom of the test chamber 2 with screws. Next, the telescopic end of the first electric telescopic rod 3 pushes the moving frame 4, causing the moving frame 4 to move the fixed box 5. This causes the moving frame 4 to move the rotating frame 18, rotating disk 19, counterweight cylinder 14, and drive column 13, positioning the hexagonal column 20 inside the hexagonal hole 21. Then, the output end of the test motor 10 drives the coupling body 11, hexagonal column 20, drive column 13, and counterweight cylinder 14 to rotate. A refrigeration unit or air conditioner is used to input cold air into the test chamber 2 through the three-way connector 22, or a hot air blower is used to input hot air into the test chamber 2 through the three-way connector 22. The two air inlets of the three-way connector 22 are equipped with valves to adjust the temperature inside the test chamber 2, thereby simulating different ambient temperatures for testing the motor 10. The working environment is simulated. When it is necessary to replace the object, the telescopic end of the first electric telescopic rod 3 drives the moving frame 4 and the fixed box 5 to reset and move. This causes the moving frame 4 to drive the rotating frame 18, the rotating disk 19, and the drive column 13 to move from the outside of the hexagonal column 20. Then, the output end of the drive motor 6 drives the worm 9 to rotate, which in turn drives the worm wheel 8 to rotate. This causes the worm wheel 8 to rotate the rotating shaft 7, which in turn drives the rotating disk 19 and the counterweight cylinder 14 to rotate. The required counterweight cylinder 14 is rotated to the working position. Then, the telescopic end of the first electric telescopic rod 3 pushes the moving frame 4 to move, which in turn drives the fixed box 5 to move. This causes the moving frame 4 to drive the rotating frame 18, the rotating disk 19, the counterweight cylinder 14, and the drive column 13 to move, so that the hexagonal column 20 is located inside the hexagonal hole 21. This allows the counterweight cylinder 14 of different weights to be replaced without opening the test box 2, simulating the test motor 10 driving the rotation of objects of different weights.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
