[0034] First, the operator clamps the motor stator to be detected through the positioning chuck 16. If it is necessary to adapt to motor stators of different sizes, the power motor 19 drives the driving bevel gear 20 to rotate, drives the two groups of driving screws 17 to rotate synchronously through the driven bevel gear 21, realizes the translation of the assembly 13. Through the adjustment component, the operator can finely adjust the position of the detection head 7 to ensure its precise alignment with the inner hole of the motor stator. The cooperation of the adjustment screw 8 and the adjustment cap 9 allows for fine adjustment to achieve the best alignment state. The servo motor 12 drives the lead screw 10 to rotate, and the threaded cooperation between the lead screw 10 and the transmission member 11 makes the moving member 3 move along the positioning slide rail 2, thereby driving the detection head 7 to move. At this time, the extension member 25 contacts the control switch 24 at the moving direction end, the drive motor 15 drives the motor stator to rotate by the positioning chuck 16, and then the detection head 7 detects the motor stator.
