[0002] With the continuous advancement of industrial technology and the extensive application of mechanical equipment, hydraulic cylinders, as actuators that convert hydraulic energy into mechanical energy, play a vital role in various mechanical systems. The hydraulic cylinder drive shaft is its core component, and its quality and reliability are directly related to the operating efficiency and safety of the entire hydraulic system. Therefore, regular non-destructive testing of the hydraulic cylinder drive shaft to promptly discover and repair potential defects is of great significance for ensuring stable equipment operation, extending service life, and reducing accident risks.

[0003] At present, non-destructive testing technology has been widely used in the industrial field. It can reveal the internal structure and defects of materials or workpieces without damaging them. This technology is mainly based on the reflection, transmission and scattering characteristics of materials to rays, sound waves, electromagnetic waves, etc. Through specific physical or chemical methods, it detects defects, anomalies or performance changes inside or on the surface of materials or workpieces. Common non-destructive testing methods include visual inspection, penetration testing, radiographic testing, ultrasonic testing, etc. The most common instrument used for non-destructive testing is the non-destructive testing instrument.

[0004] There are many types of non-destructive testing instruments on the market. These instruments are equipped with corresponding probes. By pointing the probes at the object to be tested, non-destructive testing can be performed. However, when using these instruments, they generally require manual gripping of the probes for testing. Manual gripping testing is labor-intensive and labor-intensive, which is not conducive to meeting the requirements of continuous testing of hydraulic cylinder drive shafts in assembly lines, affecting testing efficiency and causing inconvenience to users. In view of this, we propose a non-destructive testing instrument for flow-type hydraulic cylinder drive shafts. Utility Model Content
