【正文】 實(shí)力和科學(xué)技術(shù)水平的重要指標(biāo)。機(jī)械制造業(yè)的產(chǎn)品既可以直接供人們使用，也可以為其它行業(yè)的生產(chǎn)提供裝備，社會(huì)上有著各種各樣的機(jī)械或機(jī)械制造業(yè)的產(chǎn)品。 Then carries on the unit clamp the design, the choice designs the jig each position part, like locates the part, clamps the part, guides the part, to clamp concrete and the engine bed connection part as well as other parts。 全套圖紙，加 153893706 ABSTRCT This design content has involved the machine manufacture craft and the engine bed jig design, the metalcutting machine tool, the mon difference coordination and the survey and so on the various knowledge. The reduction gear box body ponents technological process and its the processing hole jig design is includes the ponents processing the technological design, the working procedure design as well as the unit clamp design three parts. Must first carry on the analysis in the technological design to the ponents, understood the ponents the craft redesigns the semi finished materials the structure, and chooses the good ponents the processing datum, designs the ponents the craft route。在工藝設(shè)計(jì)中要首先對(duì)零件進(jìn)行分析，了解零件的工藝再設(shè)計(jì)出毛坯的結(jié)構(gòu)，并選擇好零件的加工基準(zhǔn)，設(shè)計(jì)出零件的工藝路線；接著對(duì)零件各個(gè)工步的工序進(jìn)行尺寸計(jì)算，關(guān)鍵是決定出各個(gè)工序的工藝裝備及切削用量；然后進(jìn)行專(zhuān)用夾具的設(shè)計(jì)，選 擇設(shè)計(jì)出夾具的各個(gè)組成部件，如定位元件、夾緊元件、引導(dǎo)元件、夾具體與機(jī)床的連接部件以及其它部件；計(jì)算出夾具定位時(shí)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(jì)中注意改進(jìn)。their owncdsvlpa,mxukgf.()ybTqCzjSAX 設(shè)計(jì)說(shuō)明書(shū) 題目： 齒輪泵殼體 的工藝規(guī)程及 鉆 2Φ 10孔 夾具設(shè)計(jì) their owncdsvlpa,mxukgf.()ybTqCzjSAX2 摘 要 本次設(shè)計(jì)內(nèi)容涉及了機(jī)械制造工藝及機(jī)床夾具設(shè)計(jì)、金屬切削機(jī)床、公差配合與測(cè)量等多方面的知識(shí)。 齒輪泵殼體 加工工藝規(guī)程及夾具設(shè)計(jì)是包括零件加工的工藝設(shè)計(jì)、工序設(shè)計(jì)以及專(zhuān)用夾具的設(shè)計(jì)三部分。 關(guān)鍵詞 ：工藝、工序、切削用量、夾緊、定位、誤差。 After that is carrying on the size putation to a ponents each labor step of working procedure, the key is decides each working procedure their owncdsvlpa,mxukgf.()ybTqCzjSAX4 the craft equipment and the cutting specifications。 Position error which calculates the jig locates when produces, analyzes the jig structure the rationality and the deficiency, and will design in later pays attention to the improvement. Keywords: The craft, the working procedure, the cutting specifications, clamp, the localization, the error 目錄 序 言 ................................................................................................. 1 第一章 機(jī)床夾具介紹 ............................................................................ 2 1 .1 夾具的現(xiàn)狀及生產(chǎn)對(duì)其提出新的要求 ........................................ 2 現(xiàn)代夾具的發(fā)展方向 ................................................................. 3 第二章 零件的分析 ................................................................................ 5 零件的作用 ................................................................................ 5 零件的工藝分析 ........................................................................ 5 第三章 工藝規(guī)程設(shè)計(jì) ............................................................................ 6 確定毛坯的制造形式 .................................................................. 6 基面的選擇 ................................................................................ 6 制定工藝路線 ............................................................................ 7 機(jī)械加工余量、工序尺寸及毛坯尺寸的確定 ............................. 10 確定切削用量及基本工時(shí) ......................................................... 10 第四章 機(jī)床夾具的定位及夾緊 ........................................................... 19 概述 ....................................................................................... 19 機(jī)床夾具的概念 ............................................................ 19 機(jī)床夾具的組成 ............................................................ 19 機(jī)床夾具的分類(lèi) ............................................................ 20 機(jī)床夾具在機(jī)械加工中的作用 ....................................... 22 工件的裝夾方式 ....................................................................... 23 基準(zhǔn)及其分類(lèi) ......................................................................... 24 工件的定位 ............................................................................. 26 工件定位的基本原理 ..................................................... 26 常見(jiàn)定位方式及定位元件 .............................................. 27 工件的夾緊 ............................................................................. 28 夾緊裝置的組成及基本要求 ............................................ 28 夾緊力的確定 ................................................................ 29 第五章 夾具設(shè)計(jì) ................................................................................. 31 問(wèn)題的提出 .............................................................................. 31 定位基準(zhǔn)的選擇 ....................................................................... 31 切削力和夾緊力的計(jì)算 ............................................................ 32 定位誤差分析 ...........................................
