Description

Technical Field

[0001] This utility model relates to the field of motor testing technology, specifically to a switching mechanism for motor aging testing and withstand voltage testing. Background Technology

[0002] In the quality inspection process of motor manufacturing, aging testing and withstand voltage testing are key steps to ensure motor reliability. Aging testing simulates the long-term use of the motor through prolonged power-on operation to verify its stability. Withstand voltage testing tests the motor's insulation performance under a specific voltage to ensure safe use. However, during aging testing, the motor needs to be connected to a starting capacitor to ensure normal operation, while during withstand voltage testing, the starting capacitor needs to be disconnected to prevent interference with the withstand voltage test. Therefore, in existing technologies, the motor needs to be manually placed on both testing instruments for testing, resulting in low continuity and poor efficiency. Utility Model Content

However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential.

[0015] See Figures 1-5 , Figure 1 This is one of the schematic diagrams of the motor aging test and withstand voltage test switching mechanism in the embodiment. Figure 2 This is the second schematic diagram of the motor aging test and withstand voltage test switching mechanism in the embodiment. Figure 3 This is a schematic diagram of the test base structure in the embodiment. Figure 4 This is a schematic diagram of the power supply rail structure in the embodiment. Figure 5 for Figure 2Enlarged view of section A. This example illustrates a motor aging test and withstand voltage test switching mechanism, comprising a machine base 1, a circulating conveyor system 2, and a withstand voltage test mechanism 3. The circulating conveyor system 2, mounted on the machine base 1, includes a sprocket circulation mechanism 21 and multiple test bases 22. The test bases 22 are arranged along the circulation direction of the sprocket circulation mechanism 211 and move with it. The machine base 1 has multiple power supply rails 11 arranged end-to-end along the length of the machine base 1. Conductive wheels 221 are correspondingly provided on the lower surface of the test bases 22, and are in contact with the power supply rails 11. A starting capacitor and a push-button switch 222 are also provided on the surface of the test bases 22. The test bases 22 carry the motor under test, and the starting capacitor, push-button switch 222, and the motor under test are electrically connected. The withstand voltage test mechanism 3 includes a pressing component 31 and a detection component 32 located above the circulating conveyor system 2. The detection component 32 is directly opposite the movement path of the motor under test, and the pressing component 31 is directly opposite the movement path of the push-button switch 222. In practice, a power supply device is installed inside the machine 1 and connected to the power supply rail 11 to provide power to the test base 22. When in use, the test base 22 is placed on the test base 22 and electrically connected to the test base 22. The test base 22 provides power to the motor so that the motor keeps running for aging tests. When the test base 22 reaches the withstand voltage test mechanism 3, the pressing component 31 presses down the push switch 222 to disconnect the starting capacitor. At the same time, the detection component 32 abuts against the surface of the motor to perform the motor withstand voltage test. In this way, there is no need to manually switch the test instruments, which greatly improves the efficiency of motor testing.

[0016] Furthermore, the test base 22 includes a support plate 223, a conductive wheel 221 and a push switch 222 respectively disposed on its upper and lower surfaces. The test base 22 also includes a fixed base 224 disposed on the support plate 223 for fixing the motor under test. The detection component 32 is positioned directly opposite the movement path of the fixed base 224. The test base 22 also includes a wiring clamp 225 disposed adjacent to the fixed base 224 and electrically connected to the conductive wheel 221 for providing power to the motor under test.

[0017] The power supply rail 11 is divided into at least two rail sections 111 along the circulation direction. The first rail section 111 corresponds to the aging test station, where an aging test instrument is installed inside the machine base 1 and electrically connected to the first rail section 111 to provide operating voltage and perform aging tests on the motor. The second rail section 111 corresponds to the withstand voltage test station, where a withstand voltage test instrument is installed inside the machine base 1 to provide insulation test voltage to the motor. The withstand voltage test mechanism 3 is located above the second rail section 111. This design not only ensures the continuity of power supply when switching between the two test stations but also prevents the voltage differences between the two test stations from interfering with each other.

[0018] Furthermore, the pressing component 31 includes a first linear drive 311 and a pressing block 312. The pressing block 312 can press down the pressing switch 222 when the test base 22 moves to the corresponding position to disconnect the connection between the starting capacitor and the motor. In this example, the first linear drive 311 is a cylinder.

[0019] The testing component 32 includes a second linear drive 321 and a withstand voltage tester 322. The withstand voltage tester 322 can contact the motor after the starting capacitor is disconnected, and cooperate with the withstand voltage test power supply module to perform withstand voltage testing. In this example, the second linear drive 321 is also a cylinder. It can be understood that in specific implementation, a corresponding withstand voltage tester is set in the machine 1, and the withstand voltage tester 322 is connected to the withstand voltage tester to perform the withstand voltage test.

[0020] Furthermore, the sprocket circulation mechanism 21 includes a chain 211, a sprocket 212, and a sprocket drive 213. The chain 212 is driven by the sprocket 212, the sprocket 212 is driven by the sprocket drive 213, and the test base 22 is fixed on the chain 211. The sprocket drive 213 is a servo drive mechanism.

[0021] Preferably, the fixed base 224 includes a base 2241 and a pushing assembly 2242. The base 2241 includes a support 22411 and a stop 22412. The stop 22412 is located at one end of the support 22411 near the outer side of the machine base 1, and the pushing assembly 2242 is located at the other end of the support 22411 and faces the support 22411. The pushing assembly 2242 includes a pushing drive 22421 and a push block 22422. The pushing drive 22421 is a linear electric cylinder, which is also electrically connected to the conductive wheel 221. When the motor is placed on the base 2241, the pushing drive 22421 pushes the motor so that the motor abuts against the stop 22412, thereby limiting the motor position and ensuring the consistency of the motor position. In a specific implementation, the stop 22412 and the support 22411 are made of bakelite.

[0022] Preferably, the surface of the support seat 22411 has an arc-shaped groove 224111, which is arranged along the length of the support seat 22411, and the pushing component 2242 is positioned opposite one end of the arc-shaped groove 22411. This makes the support seat 22411 more compatible with the shape of the motor, ensuring the positional stability of the motor.

[0023] In summary, this example demonstrates how the coordinated structure of the test base and the withstand voltage test mechanism enables automated switching between motor aging tests and motor withstand voltage tests, effectively improving the continuity and efficiency of motor testing.

[0024] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
