Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-3 A positioning fixture device for milling machine processing includes a carrier 1 and a milling machine body 2, the carrier 1 is installed on the top of the milling machine body 2, and second clamping frames 8 are fixedly installed on both sides of the top of the carrier 1, and the top of the second clamping frame 8 is connected to a second clamping plate 9, a first clamping frame 5 is arranged on the top of the carrier 1, and one side of the first clamping frame 5 is connected to a first clamping plate 6, a gear 10 is fixed to the bottom of the first clamping frame 5, and a movable column 11 is movably connected to the bottom of the gear 10, a sliding plate 12 is fixed to the outer wall of the movable column 11, and a movable block 7 is connected to the bottom of the movable column 11, a rotating shaft 3 passes through the inner side of the movable block 7, and one end of the rotating shaft 3 is connected to the motor 4, the rotating shaft 3 and the movable block 7 are threadedly connected, and the threads arranged on the outer wall of the rotating shaft 3 have opposite directions, through the rotating The shaft 3 rotates, which can drive the movable block 7 to move toward or away from each other. Therefore, the movable column 11, the gear 10, and the first clamping frame 5 connected to the movable block 7 synchronously perform corresponding movement work, so that the parts with different placement angles can be clamped and positioned. A slide groove 13 is provided on the inner side of the top of the carrier 1, and a meshing area 14 is arranged on the upper inner side of the slide groove 13. The gear 10 and the meshing area 14 are meshed and connected, and the length of the meshing area 14 is half of the circumference of the gear 10. Through the meshing transmission work between the gear 10 and the meshing area 14, the gear 10 drives the first clamping frame 5 to rotate 180°, facing the second clamping frame 8, so as to slowly move closer, and cooperate with the second clamping frame 8 to complete the clamping and positioning of the inclined parts;

[0022] Reserved grooves 15 are provided on both sides of the top of the carrier frame 1. Through the setting of the reserved grooves 15, it can cooperate with the second clamping frame 8 to assist in clamping the parts that need to be tilted.
