  • Wheel bolt hole chamfer device
    Patent number: 10363610
    Abstract: A wheel bolt hole chamfer device is composed of a base, a support frame, a lower servo motor, a turntable, stop blocks, guide rails, strong springs, a driving friction wheel, driven shafts, driven friction wheels, chamfer cutters and the like. The device can be put into a production line as a fourth-procedure machining device, and bolt hole chamfers are no longer machined in three procedures, so that the three-procedure machining time is reduced; and after the fourth procedure for machining the bolt hole chamfers is supplemented, the machining time of a single wheel is shortened, and the efficiency is improved. The device integrates pitch diameter adjustment and rotating drive of the chamfer cutters, so that a drive system and a power system are greatly simplified, i.e., the manufacturing cost of the device is reduced, all bolt hole chamfers can be machined at the same time.
