Detailed Description

The following provides a more detailed description of the present invention with reference to the accompanying drawings and detailed description.

Referring to fig. 1-11, a portable fixture for turning the large and small ends of a conical barrel-shaped part comprises a base 1, a pressing ring 2, a pressing cover 3, a connecting shaft 4, a nut 5, a long inner hexagon screw 6, a washer 7 and a short inner hexagon screw 8, wherein the base 1 is a fixture main body, a base profile 21 of the base 1 is completely attached to the part to be machined (the conical barrel-shaped part), 6 threaded holes 9 are drilled in the base 1, a base inner hole 10 for penetrating the connecting shaft is arranged, a circular groove 22 for turning the large end of the conical barrel-shaped part is reserved at a position close to the bottom of the base 1, the wall thickness of the circular groove ensures that the part is integrally supported, and the inner position of the circular groove is hollow and reduces weight. The inner cone molding surface 15 of the compression ring 2 is partially matched with the outer molding surface of a part to be processed, and three notches 14 for measuring the size of the part and 6 through holes 13 for penetrating screws are formed in the compression ring 2; the gland 3 is used for actively pressing the compression ring 2. The connecting shaft 4 is drilled with a screw hole 17 for penetrating a screw and is provided with a thread 19, and the gland 3 is pressed through the connection of the short inner hexagon screw 8 and the nut 5.

When the small end of the conical cylindrical part is machined, the conical cylindrical part to be machined is clamped on the base 1, the profile of the conical cylindrical part is tightly attached to the profile 21 of the base 1, the pressing ring 2 is pressed on the outer profile of the conical cylindrical part, and finally the long inner hexagon screw 6 penetrates through the gasket 7 and the through hole 13 in the pressing ring 2 to be screwed on the base 1, so that machining can be conducted.

When the lathe machining is carried out to the main aspects of the cone-shaped part, in the mode, the cone-shaped part is not disassembled, the long hexagon socket head cap screws 6 are disassembled, the connecting shaft 4 is replaced, the connecting shaft 4 penetrates through the inner holes 10 of the base, the base 1 is screwed through the short hexagon socket head cap screws 8, the pressing cover 3 penetrates through the connecting shaft 4 to be pressed on the pressing ring 2, the nut 5 is screwed on the connecting shaft 4, the pressing cover 3 is pressed through the nut 4, the pressing ring 2 is pressed through the pressing cover 3, the cone-shaped part is pressed through the pressing ring 2, and the machining can be carried out.
