[0002] The hydraulic cylinder body needs to be cleaned after production is completed and after a certain period of use to remove impurities inside the hydraulic cylinder body. Existing cleaning devices generally need to go through multiple cleaning steps, such as: spraying cleaning water, brush cleaning, pneumatic blowing, etc. Existing cleaning devices usually perform the above steps separately, so multiple cleaning stations and multiple driving mechanisms are required, which is relatively cumbersome; in addition, for hydraulic cylinder bodies with different inner diameters, existing cleaning equipment uses an elastic telescopic structure to achieve comprehensive cleaning, but the elastic telescopic structure uses elastic force to make the brush fit the inner wall of the hydraulic cylinder body.
