PAGE 34 PAGE II柴油机连杆机械加工工艺及镗孔夹具设计所在学院专 业班 级姓 名学 号指导老师 年 月 日摘 要本文是对柴油机连杆零件加工应用及加工的工艺性分析，主要包括对零件图的分析、毛坯的选择、零件的装夹、工艺路线的制订、刀具的选择、切削用量的确定、加工工艺文件的填写。选择正确的加工方法，设计合理的加工工艺过程。此外还对填料箱盖零件的两道工序的加工设计了专用夹具.机床夹具的种类很多，其中，使用范围最广的通用夹具，规格尺寸多已标准化，并且有专业的工厂进行生产。而广泛用于批量生产，专为某工件加工工序服务的专用夹具，则需要各制造厂根据工件加工工艺自行设计制造。本论文夹具设计的主要内容是设计磨中心孔夹具。关键词：柴油机连杆，加工工艺，加工方法，工艺文件，夹具全套图纸加153893706 AbstractThis paper is on the bracket parts processing application and processing technology and analysis, including the parts of the plan, the choice of blank, the clamping, the craft route making, tool selection, the determination of cutting conditions, processing documents. Choose the correct processing methods, design the reasonable process. In addition to the stuffing box cover part two process designing special fixture.Machine tool fixture of many kinds, among them, the most widely used common fixture, size specifications have been standardized, and a professional production plant. While widely used in batch production, specially for a workpiece processing services for the fixture, it needs each factory according to workpiece machining technology to design and manufacture. In this paper, fixture design are the main contents of design of fixture for grinding center.Key Words: scaffold, processing technology, processing method, process documentation, fixture目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc498427997 摘 要 PAGEREF _Toc498427997 \h II HYPERLINK \l _Toc498427998 Abstract PAGEREF _Toc498427998 \h III HYPERLINK \l _Toc498427999 目 录 PAGEREF _Toc498427999 \h IV HYPERLINK \l _Toc498428000 第1章 绪论 PAGEREF _Toc498428000 \h 1 HYPERLINK \l _Toc498428001 1.1 机械加工工艺概述 PAGEREF _Toc498428001 \h 1 HYPERLINK \l _Toc498428002 1.2机械加工工艺流程 PAGEREF _Toc498428002 \h 1 HYPERLINK \l _Toc498428003 1.3夹具概述 PAGEREF _Toc498428003 \h 2 HYPERLINK \l _Toc498428004 1.4机床夹具的功能 PAGEREF _Toc498428004 \h 2 HYPERLINK \l _Toc498428005 1.5机床夹具的发展趋势 PAGEREF _Toc498428005 \h 2 HYPERLINK \l _Toc498428006 1.5.1机床夹具
