The invention discloses a machining method for a forged aluminum alloy hub of a passenger car, which comprises the following steps of: S1, roughly turning a positioning surface, enabling the end surface of a wheel lip on the outer rim side of a hub blank to be in contact with a clamp end surface block, and finishing axial positioning of the hub blank by matching with a pressing claw, S2, roughly milling a window, enabling the end surface of a wheel lip on the inner rim side after the rough turning process to be in contact with the clamp end surface block, s3, an inner side rim and a center hole are subjected to finish turning, the end face of a wheel lip on the outer rim side of the blank subjected to heat treatment makes contact with an end face block of a clamp, and axial positioning of the hub semi-finished product is completed in cooperation with the pressing claw; according to the method, the problems of unqualified jumping of the hub and the rim, window deformation, out-of-tolerance of balance and the like caused by residual stress release during window milling can be solved, the product quality and the machining precision are improved, it is ensured that the hub meets the assembly standard, the rejection rate is reduced, and the production benefit is improved.
本发明公开了一种乘用车锻造铝合金轮毂机加工方法,其包括:S1、粗车定位面,将轮毂毛坯外轮缘侧轮唇端面与夹具端面块接触,配合压爪完成对轮毂毛坯的轴向定位,S2、粗铣窗口,将粗车工序完成后的内轮缘侧轮唇端面与夹具端面块接触,配合压爪完成对轮毂半成品的轴向定位,S3、精车内侧轮辋、中心孔,将热处理后毛坯外轮缘侧轮唇端面与夹具端面块接触,配合压爪完成对轮毂半成品的轴向定位;S4、车外侧轮辋、轮毂正面,S5、钻螺栓孔、气门孔,S6、精铣窗口该方法可改善铣窗口时因残余应力释放导致的轮毂轮辋跳动不合格、窗口变形、平衡超差等问题,提升产品质量与加工精度,确保轮毂符合装配标准,减少废品率,提高生产效益。
