1、摘要本文介紹了離合齒輪的加工工藝設(shè)計過程及其專用夾具的設(shè)計過程。通過本設(shè)計進(jìn)一步了解了機(jī)械加工工藝設(shè)計過程的一般方法和步驟。聯(lián)系生產(chǎn)現(xiàn)場實(shí)際條件進(jìn)行工藝方案的比較選擇適當(dāng)方案;掌握根據(jù)生產(chǎn)的要求設(shè)計專用機(jī)床夾具的方法。本文內(nèi)容包括:機(jī)械加工工藝的組成,工藝過程的作用,工藝規(guī)程的作用,工藝規(guī)程的設(shè)計原則,生產(chǎn)綱領(lǐng)的計算和生產(chǎn)類型的確定,毛坯的制造形式,制造工藝中基準(zhǔn)的選擇,零件的尺寸、形狀誤差和位置誤差的分析,機(jī)械加工工藝路線的確定,各個工序的加工余量、工序尺寸。尺寸公差的確定及某些刀具的幾何參數(shù)的選擇和常見的金屬切削機(jī)床的選用
2、,機(jī)械加工各工序的切削深度、進(jìn)給量、些小速度的確定,機(jī)械加工工時的計算,專用夾具設(shè)計的基本要求,專用設(shè)計的依據(jù)、夾具裝置的選擇、夾緊力的估算、定位誤差的分析、夾具的操作說明。本文介紹的各個工序都要保證使用功能要求、提高勞動生產(chǎn)率,保證加工質(zhì)量、降低勞動強(qiáng)度,注意勞動保護(hù)和環(huán)境保護(hù),提高可靠性出發(fā)進(jìn)行各個工序的工藝和夾具的比較和制定。為了更好的了解各國先進(jìn)的工藝技術(shù)文本還選擇了兩篇相關(guān)的英文文獻(xiàn)進(jìn)行了可供讀者參考關(guān)鍵詞:機(jī)械加工;工藝;機(jī)械加工余量;工序;夾具;機(jī)床AbstractInthispaper,theprocessin
