摘　　要：为提高汽车车轮轮辐螺栓孔及中心孔的位置精度、加工效率,降低劳动强度,设计了一种加工汽车车轮轮辐中心孔及螺栓孔专用多头钻。针对车轮轮辐上孔的工艺特点和设计目的,本次设计的创新之处主要有两点:一是制造工艺方面,该多头钻能够在一次装夹中,完成车轮轮辐的中心孔及10个螺栓孔的加工;二是机械结构方面,在该多头钻中心轴的端部增加了浮动顶杆结构,以提高中心轴的强度和刚性,从而提高车轮轮辐中心孔的尺寸精度。专机使用结果表明:该多头钻加工效果达到了高效低成本、高位置精度、高稳定性,并具有良好的通用性。该多头钻的设计是一种工艺装备的创新,使汽车车轮轮辐的加工工艺上了新台阶,创造了良好的经济效益。One kind of special multi-spindle driller for machining the center hole and bolt holes of automobile spoke is designed to enhance position precision improve, machining efficiency and reduce labor intensity. Aiming to the process feature and design purpose of the holes on wheel spoke, there are two innovations of this design. First, on the manufacturing process, the special muhi-spindle driller can complete the processing of wheel spokes center hole and ten bolt holes in one clamping. Second, on the mechanical structure, the floating mandrel structure is added to the end of the center Spindle, in order to improve its strength and rigidity. Thus, the size accuracy of center hole on the wheel spokes is greatly improved. The results show that the special multi-spindle driller has high efficiency, low cost, high position precision, high stability and good versatility. Therefore, such a special muhi-spindle driller design for automobile wheel spoke is an innovation in technology and equipment, and also creates good economic benefits.
