1、設(shè)計(jì)說明書題目：套筒零件的工藝規(guī)程及鉆3-10孔的工裝夾具設(shè)計(jì)學(xué)生：學(xué)號：專業(yè)：班級：指導(dǎo)老師：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、公差配合與測量等多方面的知識。套筒零件的加工工藝規(guī)程及其鉆3-10孔的夾具設(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

2、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。ABSTRCTThisdesigncontenthasinvolvedthemachinemanufacturecraftandtheenginebedjigdesign,themetal-cuttingmachinetool,thecommondifferencecoordinationandthesurveyandsoonthevariousknowledge.Thereductiongearboxbodycomponentstechnolo
