Abstract

This creation is a main shaft waterproof cover structure, which includes a main shaft body and an elastic soft cover The elastic soft cover is provided with a central cover plate and a closed inclined ring on one side. The elastic soft cover is fixed on the end side of the main shaft. When the main shaft stops running, the elastic soft cover is relatively close to the cover. The end side of the main shaft body prevents water from entering. When the main shaft body is running, the elastic soft cover body is affected by the centrifugal force of rotation, so that the side closed sloping ring edge is thrown away relative to the center cover plate, and the main shaft body is located at the front end of the processing air curtain. The gas will be guided from the inner side of the side closed inclined ring to the end side of the main shaft body, forming a gas curtain that radiates outwards, preventing and blowing away the machining chips, so as to achieve the effect of good airtightness and structural function.
