Steel ball positioning type cam shaft assembly structure and cam mounting and positioning method

The invention discloses a steel ball positioning type camshaft assembly structure and a cam mounting and positioning method. The steel ball positioning type camshaft assembly structure is characterized by comprising a camshaft, a cam and a steel ball, a positioning hole is formed in the axial center of the cam shaft; a plurality of cam mounting positions are arranged on the cam shaft, and the cams are respectively mounted on the cam mounting positions; and the steel balls are respectively arranged in the positioning holes of the cam shaft. The cam and the cam shaft are combined stably, the cam shaft and the cam are separated for material selection, machining and production, the structure is stable, and meanwhile the production cost of an enterprise can be reduced. 本发明公开了一种钢球定位式凸轮轴组件结构及凸轮安装定位方法，其特征在于：包括凸轮轴、凸轮和钢球；所述凸轮轴的轴向中心设有定位孔；所述凸轮轴上设有若干个凸轮安装位，所述凸轮分别安装在凸轮安装位上；所述钢球分别安装在所述凸轮轴的定位孔内。本发明的凸轮与凸轮轴结合稳固，实现凸轮轴和凸轮分开进行选材加工生产，在具备结构稳定的同时还能降低企业生产成本。
