摘 要：本次设计抛开以往的设计思想，浓缩了一个新方案。通过对X5020B立式升降台铣床拨叉壳体厮颃胎毳遣锄衾旄遢累孛髂哎
两种加工工艺路线的比较分析，选定前者。该方案是以三个面作为基准，实现基准统一原则，简化了随行簪昼罟嵘磙魏敬猛厍洽颊各箔
夹具的设计，从而在保证所要求的质量和劳动生产率指标的前提下降低了生产成本。而且专用夹具的很沁二诵砥钶举掉晔董史砍蓣
设计严格按照先收集和研究有关资料，再确定夹具的结构方案，然后绘制夹具总图，最后确定并标注型飞息呐诲抖侥禁涧劳指劬林
有关尺寸及技术条件的步骤进行，充分体现了提高劳动生产率、保证加工质量、降低劳动强度的原则，庳伲赡镡堪蔌推剞慷绻沂廉荽

Abstract：This design gets rid of the traditional thoughts, and tries a new method. Through design techinics regulations for禽服罢墉膊贱妾擂得氦楹却淑
machining of the X5020B vertical lift platform mill machine .There are two schemes to select. At last ,we choose the former after analyzing the structure and the efficiency of the part. In this scheme, we can get to the fiducial unity and simplify special clamp designing base on three planes，so that cut down the product cost with making sure the demand of the quality and labor productivity. Also, according to getting together and studying much datum, I design the special clamp for two holes .Firstly, decide the scheme for the structure of clamp ;Secondly, draw the collectivity drawing, At last, label the joint dimensions., which enhances the work productivity, and makes certain the product quality, and reduce the labor intensity .In the paper, we layout the detailed calculate and explation. 瞅并蓉嬷凯猕陟裢隅搁敏腰载
