The present invention relates to an impeller-fixing jig for lathe machining. The purpose of the present invention is to provide an impeller-fixing jig for lathe machining whereby an impeller can be fixed firmly and swiftly to a workpiece of a lathe and precision machining can be conducted smoothly owing to the impeller not moving during lathe machining. The impeller-fixing jig for lathe machining comprises: a fixing part in the shape of a cylindrical column on the middle part of the first surface of a main body; an impeller assembly part formed concavely in the shape of a circle on the second surface of the main body; and an impeller-fixing means for fixing an impeller, which is to be mounted on the impeller assembly part, around the second surface of the main body. Moreover, the impeller-fixing means includes: multiple fixing-piece assembly grooves including bolt holes around the second surface of the main body, respectively; and fixing pins being members to be assembled to the fixing-piece assembly grooves, respectively and including a fixing-bolt moving groove in the shape of an elongated hole, which corresponds to the bolt holes, and a pressurizing protrusion having an elongated hole for bolt assembly, which is formed by penetrating the bottom surface of the fixing-bolt moving groove, and pressurizing and fixing an impeller via the tightening force of a bolt by tightening the connection part of the impeller mounted on the impeller assembly part using the bolt. |
