摘　要

　　　本文主要介紹了R180柴油機(jī)曲軸工藝設(shè)計(jì)及其中兩道工序的夾具設(shè)計(jì)。本文作者是在保證產(chǎn)品質(zhì)量、提高生產(chǎn)率、降低成本、充分利用現(xiàn)有生產(chǎn)條件、保證工人具有良好而安全勞動(dòng)條件的前提下進(jìn)行設(shè)計(jì)的。在工藝設(shè)計(jì)中，作者結(jié)合實(shí)際進(jìn)行理論設(shè)計(jì)，對(duì)曲軸傳統(tǒng)生產(chǎn)工藝進(jìn)行了改進(jìn)，優(yōu)化了工藝過(guò)程和工藝裝備，使曲軸的生產(chǎn)加工更經(jīng)濟(jì)、合理。在夾具設(shè)計(jì)部分，作者在收集加工所用機(jī)床、刀具及輔助工具等有關(guān)資料后，對(duì)工件材料、結(jié)構(gòu)特點(diǎn)、技術(shù)要求及工藝分析的基礎(chǔ)上，按照夾具設(shè)計(jì)步驟設(shè)計(jì)出符合曲軸生產(chǎn)工藝及夾具制造要求的夾具。

Abstract

　　　This text introduce R180 diesel engine crankshaft technological design and two of them jig of process design mainly. The author of this text is guaranteeing product quality, boost productivity, lower costs, utilize existing working condition, guaranteeing worker to have good work prerequisite of terms to design . In technological design, the author combine carrying on theory design, improve the traditional production technology of the crankshaft actually, optimize craft course and craft equip, enable economy rational even more of production and processing of the crankshaft. Designing in the jig , the author collect the relevant materials, such as lathe, cutter and handling tool，etc. At the foundation of the analyse of work piece material, specification requirement and craft, and make jig of request according to jig measure design and cankshaft production technology and jig.
