加工工藝規(guī)程制訂及其工序專用夾具的設計
X5020B立式升降臺銑床撥叉殼體
摘 要：本次設計拋開以往的設計思想，濃縮了一個新方案。通過對X5020B立式升降臺銑床撥叉殼體兩種加工工藝路線的比較分析，選定前者。該方案是以三個面作為基準，實現基準統一原則，簡化了隨行夾具的設計，從而在保證所要求的質量和勞動生產率指標的前提下降低了生產成本。而且專用夾具的設計嚴格按照先收集和研究有關資料，再確定夾具的結構方案，然后繪制夾具總圖，最后確定并標注有關尺寸及技術條件的步驟進行，充分體現了提高勞動生產率、保證加工質量、降低勞動強度的原則，論文中將以詳細的計算和說明證明這一說法。
關鍵詞：撥叉殼體；加工工藝；夾具
Abstract：This design gets rid of the traditional thoughts, and tries a new method. Through design techinics regulations formachining 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.
