The invention discloses a rotary edging and burring device for metal hubs. The device includes a box, the center of the top of the box is fixedly connected to a protective motor box, and one side of the bottom of the inner wall of the protective motor box is fixedly connected with a first motor through a fixing plate of the first motor, wherein one end of the first motor is rotatably connected with a first oblique gear through an output shaft, a rotating shaft is rotatably connected to the bottom of the inner wall of the protective motor box and positioned on the right side of the first motor, and the middle surface of the rotating shaft is fixedly connected with a second oblique gear through a flat key. The invention relates to the technical field of metal processing equipment. The rotary edging and burring device for the metal hubs solves the problems that during the existing edging processes of the metal hubs, manual operation is required, labor intensity is high, and the dust generated during edging causes damage to the breath function of the human body, reduces workload of workers and improves working efficiency and quality of edging, and meanwhile, the application range of equipment is expanded, and the flexibility of the equipment is improved.
