CPQ-1型叉车变速箱体加工工艺及双面钻孔组合机床主轴箱设计
摘要
本主要说明组合机床设计的基本过程及要求。组合机床是按高度集中原则设计的，即在一台机床上可以同时完成同一种工序或多种不同工序的加工。组合机床发展于工业生产末期，与传统的机床相比：组合机床具有许多优点：效率高、精度高、成本低。它由床身、立柱、工作台、及电源一些基本部件及一些特殊部件，根据不同的工件加工所需而设计的。
在组合机床上可以完成很多工序，但就目前使用的大多数组合机床来说，则主要用于平面加工和孔加工两大类工序。主要内容包括四大部分：
（1）、制定工艺方案。通过了解被加工零件的加工特点、精度和技术要求、定位夹紧情况、生产效率及机床的结构特点等，确定在组合机床上完成的工艺内容及加工方法，并绘制被加工零件工序图。
（2）、组合机床的总体设计。确定机床各部件之间的相互关系，选择通用部件和刀具的导向，计算切削用量及机床生产效率、绘制机床的尺寸联系图及加工示意图。
（3）、组合机床部件设计。包括专用多轴箱的设计，传动布局合理，轴与齿轮之间不发生干涉，保证传动的平稳性和精确性。专用主轴设计、轴承的选用及电机的选择等。
（4）、液压装置的设计。液压滑台、定位夹紧装置均为液压控制。并采用了许多液压控制阀，保证了运动的平衡性，循环性和精确性。

Abstract
This thesis mainly elucidates the basic process and requirements that design of the combination machine. Combination machine is designed according the fundamental,which highly centralized,or, more correctly it can process oneworking procedure or more differentworking procedures at one time. Combination machinewas developed in the end of industrial production comparedwith traditional machine; combination machine has many advantages, such as high efficiency, high accuracy and low cost. It is composed of some general parts, such as bed,column,work able,power unit,and some special parts designed according to differentwork piece machining need.
The preface of a lot ofworks can be completed on the combination machine, but in regard to the majority current usage of combination machine, then and primarily used for the flat surface to process and the bore to process two bigwork preface. The main part including :(1) Formulating technological plan We,ve learned the characteristic of the part designed,accuracy and specification,locating and fixing,productivity and machining structure by the practice.Then the technological operation andwork order can be determinedwhich can be finished in combination machine.(2) Combination machine frame design determines the interrelation of the different part in the machining tool,select general parts and tool oriented.Then compute cut feed and productivity finally draw a sketch map of the machine.(3) Combination machine parts design including headstock、proper transmission layout、shaft and gear move freelywithout interferencewhich ensure the stability and accuracy during transmission,then design dedicated select bearings and engine etc.(4) It adopts many hydraulic controlvalves,which ensure the stability,circulation and accuracy.
