文档介绍:
1 西安理工大学高等技术学院毕业设计题目泵体的机械加工工艺及车夹具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日期2 摘要本文是对泵体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、***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钻中心孔夹具。关键词: 泵体,加工工艺,加工方法,工艺文件,夹具 3 Abstract This paper ison 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 mon 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 1 目录摘要·············································································································· 2 ABSTRACT ··········································································································· 3 前言·············································································································· 3 第1章序言······································································································ 4 1.1 机械加工工艺概述······································································································· 4 1.2 机械加工工艺流程···························································································
