Description

Technical Field

[0001] This utility model relates to the technical field of cavity cleaning devices, specifically to a cavity cleaning device for lightweight automotive castings. Background Technology

[0002] Internal cavity cleaning devices for lightweight automotive castings, through automated design and efficient cleaning mechanisms, can significantly shorten cleaning time and improve production efficiency. For example, some devices, through the cooperation of electric telescopic rods and motors, can precisely lower the grinding block into the interior of the casting to quickly complete the cleaning work. The use of moving blocks, springs, and other designs allows the grinding block to continuously apply pressure to the inner wall of the casting during movement, ensuring uniform and thorough cleaning and avoiding the uneven cleaning problems that may occur in traditional cleaning methods.

[0003] For example, the curved inner cavity cleaning device for lightweight automotive castings disclosed in the authorization announcement number CN221640565U includes a vibrating screen and a high-pressure sandblasting machine. The high-pressure sandblasting machine is equipped with a gas collection chamber, which is connected to the casting product through a sand blowing pipe. The vibrating screen is connected to the casting product through a sand return pipe. The high-pressure sandblasting machine is connected to an interface of environmental protection dust removal equipment through a high-pressure sandblasting machine dust collection pipe, and the vibrating screen is connected to an interface of environmental protection dust removal equipment through a vibrating screen dust collection pipe.

[0004] Although it achieves the function of cleaning the inner cavity of the curved surface by setting up a vibrating screen and a high-pressure sandblasting machine, the inner cavity cleaning device of the curved surface is highly efficient, cleans thoroughly, and the casting products are subjected to uniform force, effectively avoiding damage. The inner surface roughness of the casting products is uniform, with no noise and no dust. It improves the production environment, provides a comfortable working environment, effectively improves work efficiency, and reduces work intensity.

[0005] However, this does not solve the problem that existing cavity cleaning devices of this type are generally not conducive to convenient multi-stage movement and position adjustment during use. It is not convenient for the cavity cleaning device to move the grinding head in multiple stages to adjust the position for grinding and cleaning, which affects the convenience of movement of the cavity cleaning device and the inconvenience of convenient multi-stage circumferential rotation, thus affecting the convenience and flexibility of the cavity cleaning device for rotation and grinding.
