Description

Technical Field

[0002] Polishing rods are mainly used as piston rods, shock absorber accessories, connecting rods, support rods, rack steering shafts, window worm gears and other components in the manufacturing scenarios of supporting equipment such as automobile motors, differentials, and seats. After the polishing rod is formed, its outer surface needs to be inspected using an electromagnetic ultrasonic waveguide probe. This probe can excite ultrasonic waves through an electromagnetic field in a non-contact situation and guide them to the outer surface of the polishing rod. When the ultrasonic wave propagates on the surface of the material, it will be reflected or scattered when encountering any defects or irregularities. The probe can receive these reflected or scattered ultrasonic signals and convert them into electrical signals for processing and analysis.

[0003] In the prior art, an operator is required to personally hold an ultrasonic probe and perform point-by-point or area-by-area inspection along the surface of the polishing rod. This operation method is not only slow, but also easily leads to a decrease in detection efficiency due to human factors. In addition, excessive dust and impurities attached to the surface of the polishing rod may produce misleading reflection signals, which will be received by the probe and mistakenly interpreted as defects or structural changes inside the polishing rod, affecting the detection efficiency.
