PAGE 2四川职业技术学院Sichuan Vocational and Technical毕业设计（论文）题 目十字接头零件的机械加工工艺及工装设计所属系部机械工程系所属专业机械设计与制造所属班级学 　号学生姓名指导教师起讫日期2012.09—2013.04四川职业技术学院教务处制摘 要本文是对十字接头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：十字接头，加工工艺，加工方法，工艺文件，夹具全套图纸，加153893706攀枝花学院本科毕业设计 摘 要 PAGE IAbstractThis 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 PAGE 5目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc344995884 摘 要 PAGEREF _Toc344995884 \h 2 HYPERLINK \l _Toc344995885 Abstract PAGEREF _Toc344995885 \h 3 HYPERLINK \l _Toc344995886 目 录 PAGEREF _Toc344995886 \h 4 HYPERLINK \l _Toc344995887 1 绪 论 PAGEREF _Toc344995887 \h 6 HYPERLINK \l _Toc344995888 2 零件的分析 PAGEREF _Toc344995888 \h 5 HYPERLINK \l _Toc344995889 2.1零件的工艺分析 PAGEREF _Toc344995889 \h 5 HYPERLINK \l _Toc344995890 2.2 零件的工艺要求 PAGEREF _Toc344995890 \h 5 HYPERLINK \l _Toc344995891 3 工艺规程设计 PA
