摘　　要：对汽车差速器壳十字轴孔加工中存在的问题进行了分析,提出了采用固定式多工位夹具组合机床一次装夹完成十字轴孔加工的工艺方案,并确定了机床的总体结构,对其关键部件进行了选型计算及设计。该机床使用结果表明,十字轴孔的位置精度得到保证,加工质量明显提高,同时降低了装卸工件的劳动强度,提高了生产效率。The processing problems of the cross axis apertures in automotive differential case have been analyzed, the processing program is supplied using fixed multistation fixture modular machine tools to ma- chine the cross axis apertures with one time clamping,and the main structure of the machine is sured. Then the key components of the machine have been calculated and dsigned. The using result of the machine proves that the position precision of cross axis apertures can be guaranteed and processing quality is improved. Meanwhile,the labor intensity of unloading workpieces is reduced and the production efficiency is improved.
