Lifting tool for aero-engine disc type part penetration testing

The utility model discloses a lifting tool for aero-engine disc-type part penetration testing, which comprises a disc body, the section size of the disc body is larger than the aperture of a through hole on the disc-type part, one end of the disc body is provided with a first buffer layer, and one end of the disc body close to the first buffer layer is fixedly connected with a first rod body. The diameter of the first rod body is not larger than the aperture of the through hole. According to the disc type part transfer device, the disc body and the first rod body can axially and radially limit the disc type part respectively, and when the first rod body is lifted, the disc body can lift the disc type part along with the first rod body, so that the disc type part is transferred in the penetration detection process; besides, the disc body acts on one end of the disc type part through the first buffer layer, that is, the disc body acts on the precise matching surface of the disc type part through the first buffe
