工具座盖零件图A3
摘要
在“一带一路”利好背景下，我们国家产业结构以及机械加工制造业，其结构性变化明显。企业完成工装、夹具的优化以及改良是迫在眉睫。夹具这个传统的行业，在制造业飞速发展的今天，又被赋予了新是使命。因现在产品种类繁多，零件结构万万千千。专用夹具的设计在不可取代的基础上，变的越来越重要。
本次毕设的题目是工具座盖零件的加工工艺分析及夹具设计。本工件和工具底座配合使用的，连接和紧固连接件。该零件外形复杂，需要对其进行铸造，铸造后的零件要能够承受一定的载荷。
零件加工工艺的分析不仅完成了工件结构分析、基准选择、制造和加工方式选择，还根据加工工序卡完成了相应是切削数据的计算。本次专用夹具设计设计出了铣70左端面两个工序。完成了定位夹紧方案以及装置的设计，还对夹具上其他零部件进行了设计和确定，完成设计图纸量的要求等。
关键词：工具座盖；工艺分析；专用夹具
Abstract
Under the favorable background one belt, one road, our country's industrial structure and machinery processing and manufacturing industry, its structural change is obvious. It is urgent for enterprises to complete the optimization and improvement of tooling and fixtures. Fixture this traditional industry, in the rapid development of manufacturing today, has been given a new mission. Because there are many kinds of products and thousands of parts. The design of special fixture is becoming more and more important on the basis of irreplaceable.
The title of this design is the processing technology analysis and fixture design of tool base cover parts. Theworkpiece is usedwith the tool base to connect and fasten the connector. The shape of the part is complex, so it needs to be cast, and the casting part should be able to bear a certain load.
The analysis of part processing technology not only completes theworkpiece structure analysis, datum selection, manufacturing and processing mode selection, but also completes the calculation of corresponding cutting data according to the processing procedure card. The special fixture design and design of milling 70 left end two processes. The positioning and clamping scheme and device design are completed, and other parts on the fixture are designed and determined, and the requirements of design drawings are completed.
Keywords: tool seat cover; process analysis; special fixture
