When a certain aluminum alloy shaft workpiece passes through the feeding roller table 1 of the feeding mechanism (a) and reaches the designated position, that is, the sensor 4 in the feeding area, the sensor 4 sends out a signal; Under the situation of the previous workpiece arrival signal sent at 15 places, the feeding cylinder push rod 3 can push the workpiece to be inspected to the rear feeding roller table 2.

The workpiece is transferred to the flaw detection mechanism (b) by the rear conveying roller table 2. When the workpiece reaches the flaw detection position, the sensor 15 in the flaw detection area sends out a signal, and the cylinder 14 ejects the motor 12 and the rotating wheel pair 13. The rotating wheel 13 pair is rotated by two The motor 12 drives the rotating wheel pair 13 to rotate, thereby driving the shaft workpiece located between the two rotating wheels to generate circular motion.
