Abstract
The utility model belongs to the technical field of machining devices, and relates to an auxiliary device for protecting a grinding wheel of a numerical control internal and external combination grinding machine in a non-working state, in particular to a protective cover for the external grinding wheel of the numerical control internal and external combination grinding machine. The protective cover comprises a housing base fixedly installed on a grinding head base, a housing connected to the housing base in a fastened mode, and a cover plate fixedly arranged on the housing. After the cover plate covers the housing in a pressing mode, a cavity is formed. The grinding wheel is installed inside the cavity. A gap is formed in the edge of the cavity formed by the cover plate and the housing. The grinding wheel extends out of the gap. The protective cover is characterized by further comprising a moving housing which wraps the gap inside the housing body, and the edge of the upper housing body and the edge of the lower housing body of an opening area of the moving housing cover the cover plate and the housing respectively in a pressing mode. The grinding wheel can be effectively protected with the protective cover.
