The invention discloses an automobile tail door limiting shaft and a machining method thereof.The automobile tail door limiting shaft comprises a main body part which is in a circular tube shape, an inner hole is formed in the main body part, the two ends of the inner hole penetrate to the two ends of the main body part, the inner hole is coaxial with the central axis of the main body part, limiting tooth sets are arranged at the two ends of the main body part, and each limiting tooth set comprises a plurality of limiting teeth; the limiting teeth are arranged at the end part of the main body part in a circumferential array; the limiting part is arranged on the outer side of the main body part in a sleeving mode, a plurality of limiting grooves are formed in the limiting part, and the limiting grooves are all parallel to the central axis of the main body part; wherein the main body part and the limiting part are of an integrated structure. The machining method is used for producing the automobile tail door limiting shaft. The traditional pure CNC machining is replaced by the cold heading machining and CNC machining combined technology, forming of all parts can be completed after one-time clamping, and the production efficiency is improved; and moreover, the cutting output of CNC cutting machining is reduced, and consumption of raw materials is reduced. The invention relates to the field of automobile manufacturing.

    本发明公开了一种汽车尾门限位轴及其加工方法,本汽车尾门限位轴包括主体部,其呈圆管状,主体部内设有内孔,内孔的两端贯穿至主体部的两端,内孔与主体部的中轴线同轴,主体部的两端均设有限位齿组,限位齿组包括多个限位齿,限位齿呈圆周阵列设置在主体部的端部;限位部,其套设在主体部的外侧,限位部上设有多个限位槽,限位槽均平行于主体部的中轴线;其中,主体部和限位部为一体式结构。加工方法为用于生产本汽车尾门限位轴的加工方法。本发明通过将传统的纯CNC加工替换为冷镦加工结合CNC加工的工艺,能够在一次装夹后完成各个部位的成形,提升生产效率;而且减少CNC切削加工的切削量,节省原料的消耗。本发明涉及汽车制造领域。
