The utility model discloses a cap CNC
machining jig, and relates to the field of cap CNC
machining, the cap CNC
machining jig comprises a fixing plate, a rotating
assembly and a suspender, the bottom of the fixing plate is fixedly connected with a supporting column, the inner side of the fixing plate is provided with a supporting plate, the rotating
assembly is arranged on the side face of the supporting plate, and the suspender is arranged on the rotating
assembly. And the rotating assembly comprises a fixing frame, a
servo motor, a rotating rod, a first gear and a second gear, and the hanging rods are welded to the four sides of the bottom of the supporting plate. According to the cap CNC machining jig, by arranging the rotating assembly and the limiting assembly, in the using process of CNC machining treatment on a cap through the machining jig, rotating treatment on a workpiece is achieved, subsequent machining treatment on different positions of the workpiece is facilitated, the machining jig is more efficient, meanwhile, the workpiece is limited and clamped, and the machining efficiency is improved. And the condition of deviation during subsequent workpiece machining is avoided, it is guaranteed that the machining jig conducts machining treatment on the caps smoothly, and workers can use the machining jig conveniently.
