摘要

这篇设计的论文主要阐述的是珩齿加工机床主轴箱的设计方法。珩齿加工机床是一种高精度加工机床.这个方法是以加工过程和珩齿加工机床的使用条件的数学和物理公式为基础的。
在论文中，首先，对珩齿加工机床作了简单的介绍，接着，阐述了主轴箱的设计原理和理论计算。然后按照设计准则和设计理论设计了主轴箱。接着对主轴箱的各部分组成进行了尺寸计算和校核。              
目前，在珩齿加工机床的设计、制造及应用上，国内与国外先进水平相比仍有较大差距，国内在设计制造珩齿加工机床过程中存在着较多缺点。
关键字：珩齿加工，主轴箱，机床。

Abstract

    This paper of graduation project mainly presents a systematic approach for the design of the headstock of plover machining tool, The plover machining tool is one of the members in the special high precision type machine family . the approach is based on the mathematical formulations and physical formulation on the generation process and conditions for the type of the plover machining tool.
In the paper , first of all , it is introduction about the plover machining tool .then , it is the principles about choose component parts of headstock. After that the headstock is designed abase on the principle. Then, it is checking computations about main component parts of headstock.   
 At present, we still fall far short of abroad advanced technology in design, manufacture and using. There are a lot of fault in the design of plover machining tool.
Key word: plover machining, headstock, machine.
