發(fā)動機缸蓋機械加工工藝及夾具設計【含CAD圖紙、說明書】,含CAD圖紙、說明書,發(fā)動機,缸蓋,機械,加工,工藝,夾具,設計,cad,圖紙,說明書,仿單 - 1 - 摘 要 汽缸蓋是發(fā)動機的幾大關鍵之一，零件尺寸較小，但結構形狀復雜，有若干精度要 求較高的平面和孔系。本文主要分析和設計的是汽缸蓋零件的加工工藝和、專用夾 具等。通過查閱各種相關書籍，分析缸蓋的結構及其功能，編寫了發(fā)動機缸蓋零件 的加工工藝；經過計算選擇其切削用量、選擇機床和工藝設備，設計出了專用夾具。 關鍵詞：加工工藝；發(fā)動機缸蓋；專用夾具 - 2 - Abstract The cylinder cover is one of several toll-gates to launch the engine keys, the spare parts size is smaller, but the construction shape is complicated, how many the accuracy request the higher flat surface with the bore department. Analyze primarily here with design of is a cylinder cover the spare parts processes the craft, appropriation tongs and so on .Pass to check every kind of related book, analyze construction and its functions of an urn of covers, weave to write a cover spare parts process the craft; Passing by the calculation chooses its slice the dosage of cut, choice machine tools with craft equipments, design appropriation tongs. Key words: processing technic， Engine cylinder cover; special fixture - 3 - 目錄 摘要 ......................................................I ABSTRACT.................................................II 前言 ......................................................V 1 緒論 ....................................................1 1.1 課題研究的意義及現狀 ................................1 1.2 論文主要研究內容 ....................................3 2 發(fā)動機缸蓋工藝設計 ......................................5 2.1 發(fā)動機缸蓋的分析 ....................................5 2.2 發(fā)動機缸蓋毛坯的設計 ................................9 2.3 工藝路線設計 ...................................... 14 2.4 加工設備及工藝裝備的選擇 ...........................22 2.5 加工工序設計 .......................................24 3 鉆床專用夾具設計 .......................................33 3.1 問題的提出 .........................................33 3.2 機床夾具的分類 .....................................34 3.3 夾具的設計內容 .....................................34 3.4 鉆床夾具特 點.40 3.5 鉆套與工件間的距離 .................................40 3.6 夾具的對刀 .........................................41 - 4 - 3.7 夾具體的設計 .......................................41 4 銑床專用夾具設 計.43 4.1 銑前后面專用夾具.. 43 結論 .....................................................46 參考文獻 .................................................47 致謝 .....................................................48 附錄 ...................................................49
