Description

Technical Field

[0001] This utility model relates to the field of AC motor technology, and in particular to a testing device for AC motor production. Background Technology

[0002] An AC motor is a machine used to convert mechanical energy into alternating current (AC) electrical energy. Due to the rapid development of AC power systems, AC motors have become the most commonly used type of motor. Compared to DC motors, AC motors are simpler in structure, easier to manufacture, more robust, and easier to produce high-speed, high-voltage, high-current, and high-capacity motors because they do not have a commutator.

[0003] For example, Chinese utility model patent application number 202220929392.X discloses an AC motor testing device, including a first base and a second base. A movable stage is slidably connected inside the first base. The top of the movable stage has a mounting hole, and protrusions are fixedly connected to both sides of the movable stage. A moving mechanism is provided on both sides of the first base. This utility model, through the arrangement of the first base, second base, movable stage, mounting hole, protrusions, moving mechanism, lifting mechanism, first hydraulic rod, connecting plate, connecting rod, detection mechanism, and controller, enables the AC motor testing device to mechanically transfer the AC motor to be tested, reducing the labor intensity of workers, and can detect the noise and heat generated when the AC motor is running. It solves the problems of existing testing devices, which mostly rely on manual transfer of AC motors, resulting in high labor intensity, potential danger, and inability to test the noise and heat generated when the AC motor is running.

[0004] Although the device in the aforementioned patent can test the noise and heat generated when an AC motor is running, in actual use, the motor is mounted on a moving platform, which makes the installation and subsequent disassembly of the motor consume a lot of time, reducing the efficiency of the test. In addition, during the noise test, the installed motor is also prone to vibration and noise due to improper installation, affecting the accuracy of the test. Utility Model Content

[0011] As a further description of the above technical solution:

[0012] A guide groove is provided on one side of the adjustment plate, and a guide block is slidably connected inside the guide groove. The two connecting plates are respectively fixedly connected to the two guide blocks, and the two guide blocks are arranged opposite to each other.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1-4 This utility model provides a testing device for AC motor production: It includes a base 1, with a rubber pad 13 fixedly connected to the top of the base 1, and a rubber block 14 fixedly embedded in the top of the base 1. A bidirectional electro-hydraulic rod 2, a hydraulic cylinder 3, and an electrical control box 12 are fixedly installed on the top of the base 1. Adjusting plates 4 are fixedly connected to the bidirectional telescopic ends of the bidirectional electro-hydraulic rod 2. Each of the two adjusting plates 4 is equipped with an adjusting component, two connecting plates 5, and several dampers 6. A rubber clamping plate 7 is fixedly connected to the other end of each damper 6. Two dampers 8 are fixedly connected to each of the two connecting plates 5. Springs 11 are fitted onto the outer surfaces of both dampers 6 and dampers 8. The other ends of the two dampers are fixed... A rubber clamping plate 29 is connected to the hydraulic cylinder 3, and a sealing frame 10 is rotatably connected to the telescopic end of the hydraulic cylinder 3. The sealing frame 10 is equipped with a detection component and a positioning guide component. Through the arrangement of the base 1, adjusting plate 4, damper 16, rubber clamping plate 29, sealing frame 10, guide groove 15, and bidirectional threaded rod 17, the motor to be tested can be clamped and fixed according to its size, which improves the efficiency of motor fixing. At the same time, during the noise and temperature detection process, the vibration generated by the motor can be buffered and absorbed, preventing it from colliding with external structures and generating other noise, which would affect the accuracy of the noise detection. This avoids the problem that the motor is prone to vibration and noise due to improper installation, which would affect the accuracy of the detection.

[0032] A guide groove 15 is provided on one side of the adjusting plate 4. A guide block 16 is slidably connected inside the guide groove 15. Two connecting plates 5 are respectively fixedly connected to the two guide blocks 16. The adjusting assembly includes a bidirectional threaded rod 17, which is rotatably connected inside the guide groove 15. The bidirectional threaded rod 17 is threadedly connected to the two guide blocks 16. Through the setting of the guide groove 15 and other structures of the adjusting assembly, the two corresponding positioning plates and rubber clamping plates 9 can be adjusted to clamp and fix motors of different sizes, thereby improving the stability of the motor during the testing process.

[0033] The detection component includes a decibel meter 18 and a temperature sensor 19. Both the decibel meter 18 and the temperature sensor 19 are fixedly installed on the top of the inner wall of the sealing frame 10. By setting up the detection component, the noise and temperature generated after the motor starts can be detected.

[0034] The positioning guide assembly includes a mounting block 20 and two positioning slots 21. The mounting block 20 is fixedly connected to the front of the sealing frame 10, and an elastic telescopic rod 22 is fixedly connected to the bottom of the mounting block 20. A slot 23 is opened on the front of the elastic telescopic rod 22. The two positioning slots 21 are both opened on the top of the base 1. The positioning slots 21 are adapted to the bottom end of the elastic telescopic rod 22. Through the coordinated use of the hydraulic cylinder 3, mounting block 20, positioning slots 21, elastic telescopic rod 22 and slots 23, the position of the sealing frame 10 can be easily adjusted, avoiding obstruction and blockage when the motor to be tested is loading and unloading, thereby improving the practicality of the device.

[0035] Working principle: In use, first, manually move the bottom end of the elastic telescopic rod 22 upward through the slot 23, so that its bottom end retracts and moves out of the corresponding slot 23. After releasing the limit of the sealing frame 10, rotate the sealing frame 10 to drive the mounting block 20 and the elastic telescopic rod 22 to rotate, connect it to another slot 23, limit the sealing frame 10 again, and at the same time prevent the sealing frame 10 from blocking other structures. Then, place the motor to be tested on the rubber pad 13, start the bidirectional electric hydraulic rod 2, and after its bidirectional telescopic ends retract synchronously, the two rubber clamping plates 7 can be abutted against the outer surface of the motor to fix it. Then, depending on the size of the motor, manually rotate the two bidirectional threaded rods 17. With the cooperation of the guide groove 15, the two guide blocks 16 drive the corresponding connecting plate 5 and the rubber clamping plate 9 to move, further fixing the motor and improving its placement stability.

[0036] Then, move the bottom end of the elastic telescopic rod 22 upward to release the limit of the sealing frame 10, and rotate it back to its original position. After the bottom end of the elastic telescopic rod 22 is connected to the slot 23, start the hydraulic cylinder 3 to retract its telescopic end. While the elastic telescopic end retracts, it drives the sealing frame 10 to move downward until the bottom of the sealing frame 10 abuts against the top of the rubber block 14. At this time, the fixed motor can be started, and the decibel detector 18 and temperature sensor 19 can be started to detect the noise of the motor and the temperature generated during use.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
