摘 要

在四年的大學(xué)學(xué)習(xí)中，老師教會(huì)我們學(xué)會(huì)混多關(guān)于機(jī)械設(shè)計(jì)及加工方面的知識(shí)，使我們?cè)谶@大學(xué)四年中讓我們的思維方式和思考方式有了極大的改變，為我們將來工作做了餓很多鋪墊，很快四年轉(zhuǎn)瞬既逝，畢業(yè)設(shè)計(jì)就成為我們這四年當(dāng)中最后的考試，也是檢驗(yàn)我們所學(xué)的知道的一個(gè)很好的環(huán)節(jié)。讓我們自己獨(dú)立發(fā)現(xiàn)問題并通過查資料來解決，以適應(yīng)現(xiàn)告訴發(fā)展的社會(huì)。
本次畢業(yè)設(shè)計(jì)所實(shí)涉及 查閱機(jī)械工藝手冊(cè)、夾具設(shè)計(jì)手冊(cè)等資料，對(duì)工藝設(shè)計(jì)及夾具的設(shè)計(jì)有了全面的了解。在設(shè)計(jì)過程中遇到了很多問題，如編排工藝中粗基準(zhǔn)和精基準(zhǔn)的選擇，粗基準(zhǔn)選擇工件側(cè)面，精基準(zhǔn)選擇工件底座面，最后選擇先定基準(zhǔn)面，選擇一個(gè)人為輔助基準(zhǔn)面為參考，原因裝卸方便、定位準(zhǔn)確。
經(jīng)過近3個(gè)月的努力和老師、同學(xué)的幫助，我基本上完成了設(shè)計(jì)要求。由于自身知識(shí)和能力有限，還存在不少不足之處，懇請(qǐng)各位老師給予指正。

  University graduate study is a vary important aspect of testing knowledge has been a good link.Cultivate their independence and discover information through investigation to meet the rapid development of society.
  The graduation design involved is the subject of  linen and 10 boxes of machine wallboard process design and fixture design. Through  the inspection process machinery manuals, handbooks fixture design process design and the right fixture design with a comprehensive understanding. In the design process encountered a lot of problems such as the fixture design is the use of a two-position or support plate positioning, finally adopted a two-side position, the reasons for convenient loading.There scheduling process and precision benchmart crude benchmark choice, choice benchmark crude workpiece side, precision baseline options Cradle workpiece surface.
  After nearly three months of effort and the teachrs and students to help, I have basically compleped the design requirementa. Because of its own knowledge and capacity is limited, there are still many shortcomings, urge teachers to correct.
