[0002] As we all know, cleanliness, as an important quality indicator of diesel engines, has received more and more attention in product testing, and the country and the industry have formulated relevant standards. With the improvement of diesel engine reliability requirements, the standards are also constantly improving, and the cleanliness requirements of key parts such as cylinder blocks and cylinder heads are also getting higher and higher. Since the structure of diesel engine cylinder blocks and cylinder heads is relatively complex, including casting cooling cavities, inner surfaces, processed oil channel holes and threaded holes, it is difficult to ensure cleanliness.

[0003] In order to solve the cleanliness problem in the manufacturing process of diesel engine cylinder blocks and cylinder heads, auxiliary equipment manufacturers have designed and manufactured a variety of batch parts cleaning machines for parts manufacturers. This type of cleaning machine is relatively expensive, and each cleaning machine can only clean one series of products, which is not applicable to small batches or trial production of diesel engine cylinder blocks and cylinder heads. In order to solve the cleaning problem of small batches of cylinder blocks and cylinder heads, various parts manufacturers can only use general-purpose pass-through cleaning machines or use cleaning agents for manual low-pressure / no-pressure brushing. It is difficult to fully clean the complex surfaces, cavities and hole systems of these parts, so it is impossible to guarantee the satisfactory cleanliness of these parts.

[0004] In the prior art, there is no cleaning device suitable for small-batch high-pressure cleaning of diesel engine cylinder blocks and cylinder heads. Therefore, it is absolutely necessary to provide a small-batch high-pressure cleaning device for diesel engine cylinder blocks and cylinder heads with a compact structure and good use effect. Under the premise of reducing equipment investment, high-pressure cleaning is achieved by providing good protection during cleaning, facilitating observation of parts during cleaning, and flexibly changing the cleaning position and angle of parts, thereby ensuring the cleanliness of parts.
