The part of the process and its drilling, tapping the left end surface of 6-M4 8 deep hole depth 10 threaded fixture design is including machining process design, process design and fixture design in three parts. In the process of design should first of all parts for analysis, to understand the parts of the process to design blank structure, and choose the good parts machining datum, design a part of the process route; then the parts of each step of the process dimension calculation, is the key to determine the process equipment and cutting the amount of each working procedure design; then the special fixture fixture design, selection of the various components, such as the connecting part positioning element, clamping elements, guiding elements, fixture and machine tools and other components; the positioning errors calculated fixture positioning, analysis the rationality and shortcoming of the fixture structure, pay attention to improve and design in later. Keyword: Technology, process, cutting dosage, clamping, positioning, error. 目　錄 摘要···········································································································································Ⅰ Abstract························································································································Ⅱ 緒論·············································································································································1 1概述發(fā)展·································································································································2 1.1 機床夾具簡介·················································································································2 1.1.1 機床夾具的主要功能···································································································2 1.1.2 機床夾具的組成···········································································································2 1.1.3 夾具設計的步驟和基本要求·······················································································2 2箱體的機械加工工藝規(guī)程······································································································9 2.1　毛坯的制造形式···········································································································9 2.2　零件的分析····················································································································9 2.3 基面的選擇··················································································································11 2.3.1 粗基準的選擇原則····································································································11 2.3.2 精基準的選擇原則·····································································································12 2.4 制訂工藝路線··············································································································12 2.5 確定切削用量及基本工時··························································································13 3 箱體的夾具設計···················································································································47 3.1 問題的提出····················································································································47 3.2 夾具的工作原理············································································································47 3.3 鉆套的設計····················································································································48 總結···········································································································································49 致謝···········································································································································50 參考文獻···································································································································51 IV
