[0024] Parts are generally divided into semi-finished castings and finished parts after processing. In order to meet the different needs of products, it is necessary to pressure test incompletely processed castings. Casting parts, especially precision castings with cavity structures, have very strict requirements on the pressure safety of parts, and must be 100% qualified. However, parts with complex cavity structures have problems such as loose locking of casting outlets and low operating efficiency when using traditional pressure testing methods. Such operations have great safety risks during pressure testing, which may result in product scrapping at the least and personal injury at the worst. In addition, there are many types of products and complex structures. Therefore, in order to ensure the quality of the product and the pressure-bearing safety and reliability of the product, improve the operator's portability and efficiency, and ensure the safety of the operator during the operation, a special inspection tool for pressure testing is designed for such parts. It is used to check various open defects on the surface of the casting, such as surface cracks, surface pinholes and other defects that are difficult to detect with the naked eye, to ensure the product's qualification.
