ificance: the adoption of the curriculum design, will learn theory and practice of bining production, tempered his analysis of the problem, identify problems and problemsolving abilities, in the process I am an independent analysis and solution of the mechanical parts of the manufacturing process issues, Design a machine for this fixture typical of equipment, improve the structure of design capability, enhance the professional skills for future graduates to design their own future and will be engaged in the work of an adaptation training, thus laying a good foundation. In the design of adjustment of the mentality, know how to do things carefully, confidence, tempering the will to strengthen the self.目 錄序言……………………………………………………………1一、零件的工藝分析及生產(chǎn)類型的確定…………………… 2……………………………………………2 ………………………………………… 2 二、選擇毛坯,確定毛坯尺寸,設(shè)計(jì)毛坯圖 ………………2 ………………………………………………… 2 ……………………………………… 3 …………………………………………… 3 ………………………………………………… 3三、選擇加工方法,制定工藝路線………………………… 3……………………………………………3…………………………………4………………………………………………4四、工序設(shè)計(jì)……………………………………………………5…………………………………5(工序Ⅸ)…………………………………5五、確定切削用量及基本時(shí)間(工序Ⅸ)……………………6……………………………………………6…………………………………………6六、夾具設(shè)計(jì)……………………………………………………7……………………………………………………7……………………………………………………7……………………………………………………7………………………………………8………………………………………………………8七、設(shè)計(jì)體會(huì)……………………………………………………8參考文獻(xiàn)………………………………………………………9序言機(jī)械制造技術(shù)基礎(chǔ)課程設(shè)計(jì)是在學(xué)完了機(jī)械制造技術(shù)機(jī)車和大部分專業(yè)課,并進(jìn)行了生產(chǎn)實(shí)習(xí)的基礎(chǔ)上進(jìn)行的又一個(gè)實(shí)踐性教學(xué)環(huán)節(jié)。這次設(shè)計(jì)使我們能綜合運(yùn)用機(jī)械制造技術(shù)基礎(chǔ)中的基本理論,并結(jié)合生產(chǎn)實(shí)習(xí)中學(xué)到的實(shí)踐知識,獨(dú)立地分析和解決了零件機(jī)械制造工藝問題,設(shè)計(jì)了機(jī)床專用夾具這一典型的工藝裝備,提高了結(jié)構(gòu)設(shè)計(jì)能力,為今后的畢業(yè)設(shè)計(jì)及未來從事的工作打下了良好的基礎(chǔ)。 由于能力所限,經(jīng)驗(yàn)不足,設(shè)計(jì)中還有許多不足之處,希望各位老師多加指教。一、零件的工藝分析及生產(chǎn)類型的確定通過對該零件圖的重新繪制,知原圖樣的視圖正確、完整,尺寸、公差及技術(shù)要求齊全。該零件需要加工的表面均需切削加工,各表面的加工精度和表面粗糙度都不難獲得。以下是支架需要加工的表面以及加工表面之間的位置要
