This invention proposes a masking fixture for spraying paint on a battery pack frame. The battery pack frame includes a base plate, with a frame on each side of the back of the base plate and a connecting bracket on the outer side of the frame. The masking fixture includes a masking frame, which is fitted onto the outside of the base plate, with only the front of the masking frame exposed.
