Rotary fixture for milling two side edges of angle

The invention discloses a rotary fixture for milling two side edges of an angle. The rotary fixture comprises a dividing base, wherein the center of the upper surface of the dividing base is rotatably connected with a rotary positioning disk, corresponding dividing holes are formed in the dividing base and the rotary positioning disk, positioning pins are arranged in the dividing holes, the rotary positioning disk is movably connected with the dividing base through pressing plates, positioning sleeves and bolts, and a workpiece installation mechanism is arranged on the rotary positioning disk. Guide sleeves are fixed on the rotary positioning disk, the positioning pins are located inside the guide sleeves, and springs are arranged between the positioning pins and the guide sleeves. According to the rotary fixture, the principle that distances between any point on an angular bisector and the two edges of the angle are equal is used, two faces are milled after a workpiece is clamped once, the workpiece is only required to be rotated at a certain angle, one of the two faces can be milled under the condition that a knife is fixed in a Y direction, the dimensional stability and the product quality are guaranteed, the number of times of clamping of the workpiece is reduced, the rotary fixture is especially applicable to heavy workpieces, moving of the workpieces is reduced, and the labor intensity of workers is reduced.
