減速箱體加工工藝規(guī)程及鉆6-M4孔夾具設(shè)計(jì)（含CAD圖紙和說(shuō)明書）

減速箱體加工工藝規(guī)程及鉆6-M4孔夾具設(shè)計(jì)（含CAD圖紙和說(shuō)明書）,減速,箱體,加工,工藝,規(guī)程,M4,夾具,設(shè)計(jì),CAD,圖紙,說(shuō)明書 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)。 箱體零件的工藝規(guī)程及其鉆、攻工件左端面6-M4深8孔深10螺紋的工裝夾具設(shè)計(jì)是包括零件加工的工藝設(shè)計(jì)、工序設(shè)計(jì)以及專用夾具的設(shè)計(jì)三部分。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)。 關(guān)鍵詞:工藝、工序、切削用量、夾緊、定位、誤差。 Abstract This design involves the machinery manufacturing process and fixture design, metal cutting machine tool, tolerance and measurement and other aspects of knowledge. 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(jī)床夾具簡(jiǎn)介·················································································································2 1.1.1 機(jī)床夾具的主要功能···································································································2 1.1.2 機(jī)床夾具的組成···········································································································2 1.1.3 夾具設(shè)計(jì)的步驟和基本要求·······················································································2 2箱體的機(jī)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(zhǔn)的選擇原則····································································································11 2.3.2 精基準(zhǔn)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(shí)··························································································13 3 箱體的夾具設(shè)計(jì)···················································································································47 3.1 問(wèn)題的提出····················································································································47 3.2 夾具的工作原理············································································································47 3.3 鉆套的設(shè)計(jì)····················································································································48 總結(jié)···········································································································································49 致謝···········································································································································50 參考文獻(xiàn)···································································································································51 III
