Abstract

The present disclosure relates to a sub-frame cleaning and blow-drying device, comprising a rack, a water tank, a bottom lifting assembly, supporting assemblies, a top lifting assembly, a rotating assembly, an expanding and cleaning-off assembly and a blow-drying device. Expanding assemblies expand to be connected with vehicle body mounting holes, compressed air is blown into the vehicle body mounting holes by air outlets and is blown into a cavity of a sub-frame to clean off aluminum scraps and residual sand in the cavity of the sub-frame, the rotating assembly drives the expanding and cleaning-off assembly and the sub-frame to do rotation movement to perform secondary cleaning, so that the aluminum scraps and the sand remaining inside the cavity can be cleaned off, and the sub-frame cleaning and blow-drying device can be flexibly adjusted by a position adjusting assembly according to different types of sub-frames and is strong in universality.
