摘 要
本文对减速器箱孔的加工工艺进行了详细的分析，就其孔的加工提出了“一次装夹，多工位加工，达到产品图样的精度要求”的思路。根据这一思路设计了钻孔组合机床设计。该组合机床由立柱、立柱底座、中间底座、液压滑台、动力箱、多轴箱等组成。本文对各部分的设计进行了详细的计算和论证。
在工艺制定过程中，通过批量的进行钻底孔的加工方案，并寻求最佳的工艺方案，借此说明了工艺在生产过程中的重要性。本人的设计的主要内容是：进行了机床总体布局设计；对机床的进给和传动部分进行了设计；结合实例，介绍了夹具设计方法；通过此设计，本机床完全能满足设计要求，与传统的机床相比，本机床具有自动化程度高，生产率高，精度高等优点。

Abstract
 
This paper makes a detailed analysis on the machining process of the reducer hole, the hole processing put forward "one time clamping, multi station processing, reachthe precision requirement of product pattern" idea. According to this idea, the design of drill hole modular machine tool design. The combined machine tool by the column, column base, base, hydraulic pressure sliding table, the power box, multi axle box etc.. In this paper, the detailed calculation and verification of the design of each part.
In the process of the development process, through the batch drilling bottom hole processing scheme, and to seek the best technology solutions, which illustrates the importance of the process in the production process. The main contents of the design are: the general layout design of machine tool; feed and transmission part of the machine is designed; combined with the example, introduces the design method of fixture; with this design, this machine can meet the design requirements, compared with traditional machine, this machine has a high degree of automation, high productivity, advantages high precision.
Key Words: modular machine tool; drilling bottom hole; fixture design; manual
