the method for detecting the outer wall surface of the rim by the surface detection device comprises the following steps:
a. placing the rim in an annular groove on the rotating plate, pressing a pressure plate on the rim, forcibly pressing the pressure plate, then opening an air pump to exhaust air, and fixing the rim on the rotating plate under atmospheric pressure;
b. then controlling a driving motor to rotate 360 degrees and then rotate 360 degrees in a reverse rotation mode, and in the process, operating a translation electric cylinder and a lifting electric cylinder to enable the probe to be in contact with the outer wall surface of the rim to detect the surface roughness of the rim; if the roughness is unqualified, alarming is carried out through a central processing unit and an alarm, and if the roughness is qualified, the display is passed;
c. shooting the outer wall of the rim through a camera and transmitting the shot outer wall to a central processing unit for image analysis, and detecting the defects on the surface of the outer wall of the rim;
d. and after the detection is finished, closing the air pump, opening the electromagnetic valve, taking down the pressing plate and the rim after the pressure balance inside the rim is realized, and detecting the next rim.
