[0003] When existing positioning mechanisms position gears, they usually use a downward pressure structure to clamp both sides of the gear, or position the center hole of the gear. After clamping by downward pressure, the center of the gear will be unstable, and the gear will easily shift during processing. When positioning the center hole of the gear, the edge of the gear will be lifted due to uneven force during processing, thereby affecting the processing accuracy. Utility Model Content

The output shaft of the motor 101 is fixedly connected with a screw rod 103. The top of the screw rod 103 is connected to the adjusting assembly 9 through a pin shaft. The screw rod 103 is externally threaded with a nut 102. The nut 102 is hinged to the bottom of the three supporting plates 502. Through the mutual cooperation between the screw rod 103 and the nut 102, the nut 102 can move up and down during the rotation of the screw rod 103, and can drive the clamping plates 501 to approach or move away from each other through the three supporting plates 502, so as to facilitate the positioning of gear workpieces of different specifications.
