Abstract
The utility model relates to a processing jig of inner holes of thin-wall sleeve type elements. The processing jig is novel in structure, and can effectively prevent the elements from deforming. The processing jig comprises a jig body, a press plate and fastening screws. A first through hole is formed in the center of the jig body, and is of a stepped hole. The inner diameter of a large hole in the stepped hole is the same as the outer diameter of a thin-wall sleeve type element, and the axial length of the large hole is smaller than or equal to that of the thin-wall sleeve type element. The press plate is arranged at one end, close to the large hole, of the stepped hole of the jig body, and a second through hole is formed in the center of the press plate. The inner diameter of a small hole of the stepped hole and the inner diameter of the second through hole are both larger than or equal to the inner aperture of the thin-wall sleeve type element and smaller than the outer diameter of the thin-wall sleeve type element. A plurality of positioning through holes are formed in the press plate in the circumferential direction, and are suitable for screw rod parts of the fastening screws to penetrate through, so that the press plate is pressed on the jig body.
