[0028] Working principle:

[0029] When testing the motor, the motor is mounted on the rotating base 303. The motor drives the rotating base 303 to rotate the test motor, positioning the output shaft of the test motor at the position detection component. The position detection component then detects the height of the center of the output shaft. The lifting component adjusts the height of the lifting platform 302 and the test motor, aligning the output shaft of the test motor with the power output shaft of the testing mechanism. The rotating base 303 then drives the test motor to rotate, causing the output shaft to face the testing mechanism. The moving component adjusts the position of the test base 3 and the test motor, connecting the output shaft of the test motor to the testing mechanism for subsequent testing. The position detection component detects the position of the test motor's output shaft, and the lifting component adjusts the position accordingly, improving the accuracy of the motor's output shaft position and enabling a quick and accurate connection between the motor's output shaft and the power output shaft of the testing mechanism.

[0030] After the test motor is installed on the rotating base 303, the electromagnet 406 on the position detection frame 4 is energized. The two electromagnets 406 in the same spring slot attract each other, causing the upper pressure block 405 and the lower pressure block 404 to retract into the spring slot. Then, the motor drives the rotating base 303 to rotate the test motor, causing the output shaft of the test motor to rotate between the upper pressure block 405 and the lower pressure block 404. The electromagnet 406 is de-energized, and the upper pressure block 405 and the lower pressure block 404 contact the output shaft through their respective slots and automatically adjust their positions through their respective springs. The distance between the upper boss and the bottom surface of the mounting base 101, as well as the distance between the upper boss and the lower boss, are measured by the distance measuring sensor to determine the height position of the output shaft of the test motor. After adjusting the position of the output shaft of the test motor through the lifting assembly, the rotating base 303 returns to its original position, the electromagnet 406 is de-energized, and the upper pressure block 405 and the lower pressure block 404 return to their original positions.

[0031] Once the position detection component detects the center position of the output shaft of the test motor, it drives the two threaded cylinders 308 to rotate through the dual-shaft motor, bevel gear 310, and bevel gear ring 309. Through the thread action, the two screws 307 drive the lifting platform 302, its rotating seat 303, and the test motor to move, thereby adjusting the center position of the output shaft of the test motor.

[0032] After the center position of the output shaft of the test motor is adjusted and rotated to the connecting flange 206, the motor causes the lead screw 306 to rotate, and the moving block 305 drives the test base 3 to move along the moving groove 102, adjusting the position of the test base 3 and the test motor on it, so that the flange on the output shaft of the test motor can contact the connecting flange 206 for subsequent connection.

[0033] The test motor is connected to the experimental motor 201 by connecting flange 206 to the flange on the output shaft of the test motor, so that simulation testing can be performed using the test motor and the corresponding structure.

[0034] Example 2. The structure of this example is basically the same as that of Example 1, except that,

[0035] The bottom of both side walls of the test base 3 are symmetrically provided with heat dissipation grooves 301, which are connected to the inner cavity of the test base 3; a dustproof net is fixed in the heat dissipation groove 301.

[0036] The heat dissipation slots 301 provide ventilation and heat dissipation for the internal structure of the test base 3, and the dustproof net prevents external dust and other substances from entering the test base 3.

[0037] Example 3. The structure of this example is basically the same as that of Example 1, except that...

[0038] The bottom of the position detection frame 4 is symmetrically fixed with multiple triangular reinforcing plates 401; one end of each reinforcing plate 401 is fixedly connected to the upper side wall of the test base 3. The reinforcing plates 401 improve the connection stability between the position detection frame 4 and the test base 3.

[0039] The bottom of the rotating seat 303 is provided with multiple concentric ball grooves from the inside out, and each concentric ball groove contains multiple balls evenly arranged along the circumference of the rotating seat 303; the rotating seat 303 contacts the top surface of the lifting platform 302 through the balls. When the rotating seat 303 rotates, the contact between the rotating seat 303 and the top surface of the lifting platform 302 through the balls provides positional stability of the rotating seat 303 while reducing friction when the rotating seat 303 moves relative to the lifting platform 302.
