摘 要
本文主要论述了液压设计。因为液压是活塞式发动机和压缩机的主要零件之一,其大头孔与曲轴连接,小头孔通过活塞销与活塞连接,其作用是将活塞的气体压力传送给曲轴,又收曲轴驱动而带动活塞压缩汽缸中的气体。连杆承受的是冲击动载荷,因此要求连杆质量小,强度高。所以在安排工艺过程时,按照“先基准后一般”的加工原则。连杆的主要加工表面为大小头孔和两端面,较重要的加工表面为连杆体和盖的结合面及螺栓孔定位面。 在夹具设计方面也要针对连杆结构特点比较小,设计应时应注意夹具体结构尺寸的大小等,最终就能达到零件的理想要求!

Abstract
The diesel connecting rod treating handicraft the main body of a book has been discussed mainly and their grip design. Because of the connecting rod is one of dyadic engine of piston and main compression engine part, whose larger end hole and crank shaft link up , the small head hole links up by the wrist pin and the piston , whose effect is that the piston gas pressure is transmitted to the crank shaft , collect crank shaft gas in driving but setting a piston in motion to compress a cylinder. Being that the pole bears pounds a live load , request connecting rod mass is minor therefore , the intensity is high. Therefore when arranging procedure for, according to "first the criterion queen-like " treating principle. The connecting rod main part processes a surface being that head hole and both ends big or small are weak, more important faying face and bolt hole locating surface being the connecting rod body and cover treating outside. Also should be comparatively small specifically for connecting rod structure characteristic in the field of grip design , design that the size should pay attention to gripping the concrete structure dimension of the season waits, the ideal being therefore likely to reach a part ultimately demands!

第一章 引言
1.1数控机床的特点
在数控技术中,所谓的加工程序,就是把零件的加工工艺路线、工艺参数、刀具的运动轨迹、切削参数以及辅助动作等,按照数控机床规定的指令代码及程序格式编写成加工程序单,再把程序中的内容通过控制介质或直接输入到数控机床的数控装置中,从而控制机床加工零件。
数控编程分为手工编程和自动编程。手工编程是从零件图样确定工艺路线,计算数值和编写零件加工程序单,制备控制介质到校验程序都由人工完成。对于形状简单零件的加工,计算比较简单,程序较短,采用手工编程可以完成,但对于形状复杂的零件,特别是
