内容简介：

盐城工学院毕业设计说明书 2006半精镗及精镗气缸盖导管孔组合机床设计（夹具设计）摘要：本组合机床是气缸盖半精镗、精镗组合机床，在完成 “三图一卡”的基础上，主要完成夹具设计。这个课题来源于江苏高精机电装备有限公司，是为了适合流水线生产，提高目前的生产效率、加工精度，从而降低加工成本而设计的。在设计过程中借鉴了国内外一些现有的组合机床设计资料，还参考了一些与本课题相关的文献资料。 设计的主要内容为组合机床的总体设计和夹具的设计。夹具的设计是本次设计中一个重要的部分。在夹具设计方面，首先，原有机床采用多工序加工，加工效率低，加工尺寸不容易保证，而且位置精度也不高。改进后，采用一次装夹，同时对进气和排气孔进行镗加工，提高了加工效率。其次,夹具采用一面两销定位，保证了导管孔及气门阀座孔对定位销孔的位置精度。夹紧方式采用液压夹紧，改变了原来的手动夹紧，提高了工作的效率。最后，对相应部分进行了计算、分析、校核。本组合机床具有提高生产效率，满足工件的加工精度，减少了工人的劳动强度的优点，较好的实现了设计的要求。关键词：组合机床；夹具；定位；夹紧The modular machine tool design for half finished and finished boring of cylinder cap pipe hole (jig design)Abstract: The modular machine-tool is defined as half finish and full finish boring machine with cylinder lids. In addition to the accomplishment of “Three drawings and one card”, the major task is to finish the design of jigs. The project originally from Jiangsu Gaojing Mechanical & Electrical Equipment CO.,LTD. Ltd aims to cater to the assembly line and improve effectiveness and processing precision so as to reduce the cost. During the process of design, I drew lessons from international and national data, and referenced some literature material related to the topic.The designs cover the overall ones of the assembled machine and jigs. Firstly, as far as jig design, the main part of the designs, is concerned, the original machine tool has characteristic of multi working procedure machining, effectiveness, difficult machining size guarantee, and low location precision. After being improved, both the air inlet louver and outlet louver are bored by jigging just once, which not only improves effectiveness but also guarantees machining hole sizes. Next, in order to ensure the process precision and production efficiency of boring machine tool ,the jig uses one surface-two sell .the way of Clamps is hydraulic pressure clamping, which replaced by Manual clamping. It can enhanced the work efficiency. At last, carry on the computation, the analysis, the examination to corresponding parts. The advantages of this modular machine-tool are production efficiency, high precision of
