Metal surface treatment device integrating grinding and cleaning

The invention relates to the field of surface treatment devices, in particular to a metal surface treatment device integrating grinding and cleaning. The technical problem that in the surface treatment process of an existing metal surface treatment device, in one-way grinding operation is conducted on a mechanical structure, due to the fact that adhesion impurities exist on a metal blank and welding spots are scattered, an uneven state is generated is solved. According to the technical scheme, the metal surface treatment device integrating grinding and cleaning comprises a protective grinding box, a directional grinding connecting module, a magnetic suction sealing door, a cleaning control assembly, an adjustable grinding assembly, a dust collecting box and a positioning pressing assembly; and according to different metal shapes, the adjustable grinding assembly is used for conducting steering adjustment so that surface grinding operation can be conducted on the metal parts, when the heights of the surfaces o
