Abstract: The present application provides a chamfer removing device for wheels. The device may be used for removing a bolt hole chamfer on flange side of back cavity of a wheel in hub machining process. Drill bits are spaced a certain height from the flange side of the wheel by adjusting the relative height of an external thread guiding sleeve in an internal thread guiding sleeve, a motor and gears drive the drill bits to rotate, and a cylinder and a sliding box drive the drill bits to move up and down so as to realize chamfer removing function.
