First of all for the parts on some of the main processing surface, access to a large number of professional material to decide its processing technology, ensure the precision of parts, demands for dimensional tolerance is also involved through various detailed calculation and evolve. In order to give processing components to provide complete written explain, in this manual of the role of the cylinder block and working environment of a detailed introduction, involved in the reference also detailed list. Finally, in the course of processing for the kind of fixture design principles will be discussed, and gives a boring and fixture design scheme. In short, in line with complete, detailed, correct principles, the need for analysis and calculation of the place in this manual all has the corresponding reflect, and finally to the production and processing of parts provide the original data. 目录 TOC \o "1-3" \h \z \u HYPERLINK \l "_Toc322812379" 绪论 PAGEREF _Toc322812379 \h 5 HYPERLINK \l "_Toc322812380" （1）课题背景及发展趋势 PAGEREF _Toc322812380 \h 5 HYPERLINK \l "_Toc322812381" （2）夹具的基本结构及夹具设计的内容 PAGEREF _Toc322812381 \h 5 HYPERLINK \l "_Toc322812382" 第一章 零件的分析 PAGEREF _Toc322812382 \h 7 HYPERLINK \l "_Toc322812383" 1.1零件的作
