Because of the connecting rod is one of dyadic engine of piston and main compression engine part, whose larger end 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 arranging procedure for, according to first the criterion queen-like treating principle. The connecting rod main part processes a surface being that 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!Keyword: Connecting rod Deformination Processing technology Design of clamping device 目 录 目 录  PAGE 27 目 录  TOC \o 1-3 \h \z \u 摘 要  PAGEREF _Toc275630563 \h I Abstract  PAGEREF _Toc275630564 \h II 第一章 柴油机连杆的加工工艺  PAGEREF _Toc275630565 \h 1 1.1 柴油机连杆的用途及其特点  PAGEREF _Toc275630566 \h 1 1.2　连杆的的材料及毛坯制造  PAGEREF _Toc275630567 \h 1 1.3　连杆的加工工艺过程  PAGEREF _Toc275630568 \h 2 1.4 连杆的加工工艺过程分析  PAGEREF _Toc275630569 \h 2 1.4.1定位基准的分析  PAGEREF _Toc275630570 \h 2 1.4.2定位基准的选择  PAGEREF _Toc275630571 \h 3 1.4.3 加工阶段的划分和加工顺序的安排  PAGEREF _Toc275630572 \h 4 1.4.4 确定合理的夹紧方法  PAGEREF _Toc275630573 \h 5 1.4.5 连杆主要面的加工方法  PAGEREF _Toc275630574 \h 5 1.4.6 连杆主要孔的加工方法  PAGEREF _Toc275630575 \h 5 1.4
