[0040] Meanwhile, the contents not described in detail in the specification all belong to the prior art known by those skilled in the art.

[0041] The working principle of this device is as follows: When working, the electric push rod 22, the feeding push rod 41, the infrared sensor 44, the clamping push rod 47, and the receiver 411 are first electrically connected through the external power supply and controller. When the coaxiality of the motor base is detected, the motor base is first placed on the top of the placement table 410, and the appropriate clamping component is selected according to the different types of motor bases.

[0042] The trapezoidal block 25 is inserted into the inner wall of the trapezoidal groove 24 by the movable V-shaped clamp 27 and the movable frame 26, so that the outer wall of the trapezoidal block 25 is in contact with the inner wall of the trapezoidal groove 24, and the side wall of the movable frame 26 is in contact with the side wall of the movable platform 23. Then, the movable limit seat 28 drives the abutment seat 29 and the trapezoidal seat 211 to move downward, so that the abutment seat 29 enters the inner wall of the through 212, the bottom wall of the limit seat 28 is in contact with the top wall of the movable platform 23, and the trapezoidal seat 211 enters the inner wall of the trapezoidal groove 24 and then abuts and fixes against the top wall of the trapezoidal block 25. Then, the movable insertion rod 214 passes through the limit port 213 and enters the insertion interface 210 and then abuts and fixes against the abutment seat 29, thereby completing the installation and fixing of the clamping component.

[0043] Next, the electric actuator 22 is activated to push the moving platform 23, the moving frame 26 and the V-shaped clamp 27 to extend synchronously by the same length, so that the V-shaped clamp 27 clamps and fixes the outer wall of the motor base, so that the motor base is located at the center of the insertion interface 210.

[0044] The matching motor shaft top is placed into the inner wall of the positioning port 45 on the bottom wall of the positioning seat 46, and the anti-slip clamp 48 is pushed by the clamping push rod 47 to clamp and fix the outer wall of the motor shaft synchronously, so that the motor shaft is located at the center above the insertion interface 210 and always remains vertical, and the infrared sensor 44 installed on the mounting seat 49 always corresponds to the receiver 411 in position.

[0045] When the push rod 41 pushes the U-shaped seat 43 down, it also drives the positioning rod 42 down to prevent positional displacement. When the U-shaped seat 43 is down, it will drive the positioning seat 46 and the clamped and fixed motor shaft down. The infrared sensor 44 emits infrared rays that are always received by the receiver 411. The external controller can view the spectrum reception diagram in real time to avoid positional displacement of the motor shaft when it is down. When the motor shaft continues to fall, it will enter the motor seat. When the motor shaft enters the mounting hole on the motor seat smoothly, it indicates that the coaxiality of the motor seat is good. When the motor shaft cannot enter smoothly, it indicates that there is a deviation in coaxiality.
