[0023] When processing cylindrical mechanical parts, the staff first places the cylindrical mechanical parts on the upper end of the placement table 2 at the center of the upper end of the positioning platform 1, and then the double-headed drive motor 4 in the positioning platform 1 works to synchronously drive the two worms 5 to rotate in the same direction. With the cooperation of the worm 5 and the worm wheel 7, the worm wheel 7 and the gear 8 rotate synchronously on the upper end of the fixed shaft 6. During the rotation of the gear 8, it engages with the arc-shaped rack 11 at the lower end of the rotating mounting rod 10, so that the arc-shaped rack 11 moves on the upper end of the gear 8 and drives the two rotating mounting rods 10 to rotate on the upper end of the mounting shaft 9 until the adjustment and fixing assembly located at the upper end of the rotating mounting rod 10 contacts both sides of the cylindrical mechanical parts, thereby clamping and positioning the cylindrical mechanical parts.
