The invention discloses a rotating cutter wheel control structure of a rod rolling machine of a wheel hub. The rotating cutter wheel control structure comprises a fixed support, a movable support, a first ball screw pair, a second ball screw pair, a first motor, a second motor, a rotating cutter wheel support, a first chain wheel shaft, a second chain wheel shaft and a chain. According to the rotating cutter wheel control structure, the structure is ingenious and reasonable in design, during machining, the second motor drives the chain to run through the second ball screw pair, then the firstchain wheel shaft is driven to rotate, so that the purpose of driving the rotating cutter wheel support to rotate by an angle is achieved, a free shaft is added compared with a traditional spinning machine of the wheel hub, a freedom degree of the spinning machine of the wheel hub is increased, and functions of the rod rolling machine of the wheel hub are expanded, and the rod rolling machine of the wheel hub can be applied to more complex curved surface machining; moreover, the rotating angle can be accurately and effectively controlled through the first motor, the operation is easy, the machining precision is high, the spinning effect is effectively improved, and the product quality is guaranteed; and in addition, the overall structure is compact, the working stability is good, the abrasion is not easy, the service life is long, and wide popularization and application are facilitated.
