Zusammenfassung:The utility discloses a positioning structure for a small hole punching die of a gear part, which comprises a gear, a positioning plate, a screw, a cylindrical pin and a female die, wherein the center hole of the gear is fixed on a positioning nail O; the positioning plate is provided with a first through hole and a second through hole; the cylindrical pin is fixed on a female die surface through the first through hole; the positioning plate can rotate around the cylindrical pin; and the screw penetrates through the second through hole to fix the positioning plate on the female die surface. The positioning structure has the beneficial effects that a working surface of the positioning structure is embedded between two teeth of the gear so as to realize clamping and positioning; when different batches of gear parts are processed, the errors of the center holes and tooth forms of the gear parts, which are generated in the machining process, can be eliminated only by regulating the working surface of the position
