Description

Technical Field

[0001] The present invention relates to the technical field of motor inspection, and in particular to a motor inspection device and a method for using the same. Background Art

[0002] Electric machinery, commonly known as motors, refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. A motor usually consists of a stator and a rotor. The stator consists of a stator core and a coil winding wound on the stator core. The rotor consists of a rotating shaft and a rotor core sleeved on the rotating shaft. A permanent magnet is provided on the outer edge of the rotor core. Motors are generally divided into DC motors and AC motors. The motor is represented by the letter M in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machines. According to the type of working power supply, it can be divided into DC motors and AC motors. DC motors can be divided into brushless DC motors and brushed DC motors according to their structure and working principle. Brushed DC motors can be divided into permanent magnet DC motors and electromagnetic DC motors. Electromagnetic DC motors can be divided into series-excited DC motors, shunt-excited DC motors, separately-excited DC motors and compound-excited DC motors. Permanent magnet DC motors can be divided into rare earth permanent magnet DC motors, ferrite permanent magnet DC motors and alnico permanent magnet DC motors.

[0003] The torque of the motor is the output torque and is one of the basic parameters. In order to ensure the factory quality of the motor, the output torque of the motor must be tested before leaving the factory to check whether it is qualified, and unqualified products must be selected, and motor performance testing, mechanical environment testing, and climate environment testing are required. When performing motor performance testing on the motor, it is necessary to use a motor dynamometer to perform no-load tests, load tests, maximum torque and minimum torque tests, starting torque and starting current tests on the motor. The main purpose of these tests is to examine the heat resistance level, output capacity, service life and adaptability to abnormal operation of the motor under test. When testing the sampled motor, it is necessary to align the motor shaft with the coupling on the motor dynamometer, insert the motor shaft into the coupling, and then use the device to fix the motor to fix the motor. After tightening the coupling, the motor can be tested.

[0004] The prior art discloses a motor torque testing device, with publication number CN112362207A, which includes a workbench and a supporting and fixing mechanism. A through slot is provided on the workbench, and the supporting and fixing mechanism is located in the through slot. A first mounting seat is provided in the middle position of the workbench, a bearing seat is provided at the left end of the first mounting seat, and a second mounting seat is provided at the right end of the first mounting seat. A speed torque sensor is fixed on the first mounting seat, a rotating shaft connector is provided on the bearing seat, and a magnetic powder brake is fixed on the second mounting seat. The present invention changes the distance between the first arc-shaped clamping seat and the second arc-shaped clamping seat by moving the slider in the slide slot, which is convenient for clamping and fixing motors of different models and sizes, and reduces the vibration generated during the operation of the motor through the provided shock-absorbing spring and sponge column, thereby increasing the test accuracy.

[0005] When connecting the motor under test to the motor dynamometer, workers need to load each motor individually. This requires a long time to assemble before each test. Changing the motor also requires a long time to loosen the bolts at various locations before removing the motor under test. This results in extremely long motor testing times, and the motor replacement operation is cumbersome, time-consuming, and labor-intensive, hindering rapid motor production. To address this issue, we provide a motor inspection device and its use method to address these issues. Summary of the Invention

[0021] 2. The present invention inserts the output end of the motor to be tested into the output shaft fixing sleeve, and the electric hydraulic rod drives the mobile frame to move forward, and the mobile frame drives the rotating ring to move to the outside of the adjusting sleeve. At this time, the servo motor C drives the adjusting gear disk to rotate through the connecting wheel, and the adjusting gear disk drives the adjusting sleeve to rotate through the toggle rod.
