For example, the rotating part 12 can be a servo motor, and the detection mechanism 2 can be arranged on the outside of the workpiece 4, opposite to the side of the workpiece 4, and the side is the side of the workpiece 4 to be detected. While the fixing mechanism 1 fixes the workpiece 4, the servo motor rotates the workpiece 4 on the fixing part 11, so that the detection mechanism 2 can perform a comprehensive detection of the outer peripheral surface of the workpiece 4, realize automatic detection, and improve the accuracy of detection.

[0040] As a specific implementation method, Figure 1 and Figure 7 As shown, the detection mechanism 2 includes a detection bracket and a line scan camera 21 arranged on the detection bracket.

The rotating part 12 drives the workpiece 4 on the fixing part 11 to rotate, so that the line scan camera 21 continuously photographs the lines of the workpiece 4, thereby gathering the lines into a surface, and taking a complete photo of the outer surface of the workpiece 4.
