During the rotation of the rotating wheel, the detection head 5 detects the rotating wheel in real time, and feeds back the detection data on the display screen 9 through the detection system. According to the stability of the data displayed on the display screen 9, the speed regulator is debugged to control the rotation speed of the rotating wheel;

[0101] S4: After adjusting the rotation parameters, the parameter signal is received by the signal receiving module, and the signal processing module processes the received signal to decompose the required voltage and current of the motor 301, and then respectively adjusts the voltage and current values ​​to the corresponding values ​​through the voltage control module and the current control module, so as to adjust the required rotation speed of the motor 301, and finally determines it by the determination module, so that when the rotating wheel rotates, the detection head 5 can stably and efficiently detect the rotating wheel, see Figure 6 .

[0102] In summary, the beneficial effects of the present invention are as follows:

[0103] 1. Compared with the prior art, according to the stability of the data displayed on the display screen by the detection head during debugging, the speed regulator can be debugged to control the rotation speed of the rotating wheel. After adjusting the rotation parameters, the rotation parameters are decomposed into the required voltage and current of the motor to be adjusted, so as to adjust the required rotation speed of the motor, so that when the rotating wheel rotates, the detection head can stably and efficiently detect the rotating wheel, so as to ensure that the detection head can stably detect the rotating wheel at the maximum rotation speed of the turntable, so as to improve the detection efficiency and stability of the rotating wheel;

[0104] 2. Through the setting of the hydraulic table, the connecting block and the electric push rod, compared with the prior art, the height of the detection head can be adjusted by the lifting of the hydraulic table, and the distance between the detection head and the rotating wheel can be adjusted by the operation of the electric push rod, so that it is convenient to detect rotating wheels of different sizes, thereby improving the size range of the rotating wheel detection by the turntable.
