ABSTRACT This thesis combination machine for design processing many stalks the box ten screw threads of rights the bore to the processing work piece dimensional drawing and the production request, reasonable draws up the design proposal, completes this engine bed various parts and the system design, mainly includes the processing working procedure the formulation, the main axle, the cutting tool choice, the multi-axle-boxes and the sliding table select reasonably, in headstock transmission system hypothesis, jig design, as well as formulation hydraulic pressure and control system. In the design process, while satisfies the design request, should pay attention to mutually the reasonable coordination, like this can grasp the aggregate machine-tool overall the performance and the structure. For making design to meet the modern request, and reshuffle to match the machine bed to adopt the PLC to control the system to control the revolving of machine bed, PLC control to have the function perfect, in general use and vivid, in brief and easily understand, operation convenience with price cheapness etc. Advantage, this not only satisfied the modern society to demand production also now the request of the humanized design. Key words：Spindle box; Fixture; hydraulic;plc 目 录 第1章 绪 论 1 课题背景及实际意义 1 本次课题的研究内容 1 组合机床的发展展望 2 第2章 总体方案设计 3 本次设计的总体目标 3 机械部分可行性分析 3 控制部分可行性分析 7 第3章 组合机床多轴箱设计 8 确定切削力、切削转矩、切削功率 8 机床联系尺寸选择与计算 8 机床联系尺寸总图的作用与内容 11 绘制机床联系尺寸总图之前应确定的主要内容 11 机床生产率计算卡 14
