圓周支座工藝規(guī)程及專用夾具設(shè)計【3副】（含全套CAD圖紙）,3副,圓周,支座,工藝,規(guī)程,專用,夾具,設(shè)計,全套,cad,圖紙 摘 要 I 摘 要 圓周支座零件加工工藝及夾具設(shè)計是包括零件加工的工藝設(shè)計、工序設(shè)計以 及專用夾具的設(shè)計三部分。在工藝設(shè)計中要首先對零件進行分析，了解零件的工 藝再設(shè)計出毛坯的結(jié)構(gòu)，并選擇好零件的加工基準，設(shè)計出零件的工藝路線；接 著對零件各個工步的工序進行尺寸計算，關(guān)鍵是決定出各個工序的工藝裝備及切 削用量；然后進行專用夾具的設(shè)計，選擇設(shè)計出夾具的各個組成部件，如定位元 件、夾緊元件、引導元件、夾具體與機床的連接部件以及其它部件；計算出夾具 定位時產(chǎn)生的定位誤差，分析夾具結(jié)構(gòu)的合理性與不足之處，并在以后設(shè)計中注 意改進。 關(guān)鍵詞：工藝，工序，切削用量，夾緊，定位，誤差 Abstract - II - Abstract A machining process and fixture design is the design process, including the design of bearing parts processing process design and the three part special fixture. In the process of design should first of all parts to analyze, understand parts of the process and then design a blank structure, and choose the good parts of the machining datum, designs the process routes of the parts; then the parts each step process dimension calculation, the key is to determine the process equipment and cutting the amount of each working procedure design; then a special fixture, fixture for the various components of a design, such as the connecting part positioning device, clamping element, a guide element, clamp and the machine tool and other components; the positioning error caused calculate fixture when positioning, analysis of the rationality and deficiency of fixture structure, pay attention to improving and will design in. Keywords: process, process, cutting, clamping, positioning 致 謝 3 目 錄 摘 要 ................................................................................................................................I ABSTRACT......................................................................................................................II 第 1 章 緒論 .....................................................................................................................1 第 2 章 加工工藝規(guī)程設(shè)計 .............................................................................................2 2.1 零件的分析 ............................................................................................................2 2.1.1 零件的作用 .....................................................................................................2 2.1.2 零件的工藝分析 .............................................................................................3 2.2 圓周支座零件加工的主要問題和工藝過程設(shè)計所應(yīng)采取的相應(yīng)措施 ............3 2.2.1 孔和平面的加工順序 .....................................................................................3 2.2.2 孔系加工方案選擇 .........................................................................................3 2.3 圓周支座零件加工定位基準的選擇 ....................................................................4 2.3.1 粗基準的選擇 .................................................................................................4 2.3.2 精基準的選擇 .................................................................................................4 2.4 圓周支座零件加工主要工序安排 ........................................................................4 2.5 機械加工余量、工序尺寸及毛坯尺寸的確定 ....................................................6 2.6 確定切削用量及基本工時（機動時間） .............................................................6 第 3 章 銑底面夾具設(shè)計設(shè)計 .......................................................................................13 3.1 研究原始質(zhì)料 ......................................................................................................13 3.2 定位、夾緊方案的選擇 ......................................................................................14 3.3 切削力及夾緊力的計算 ......................................................................................14 3.4 誤差分析與計算 ..................................................................................................15 3. 5 定向鍵與對刀裝置設(shè)計 ......................................................................................16 3.6 確定夾具體結(jié)構(gòu)和總體結(jié)構(gòu) ..............................................................................18 3.7 夾具設(shè)計及操作的簡要說明 ...............................................................................19 第 4 章 鉆 13 孔夾具設(shè)計 ..........................................................................................20 4.1 夾具的夾緊裝置和定位裝置 ..............................................................................20 4.2 夾具的導向 ..........................................................................................................20 4.3 切削力及夾緊力的計算 ......................................................................................21 4.4 鉆孔與工件之間的切屑間隙 ..............................................................................23 4.5 鉆模板 ..................................................................................................................23 哈爾濱工業(yè)大學工學博士學位論文 -
