1、太原工業(yè)學(xué)院畢業(yè)設(shè)計(jì)數(shù)控沖床自動(dòng)送料機(jī)機(jī)械結(jié)構(gòu)設(shè)計(jì)摘要　　本課題對(duì)數(shù)控沖床自動(dòng)送料機(jī)進(jìn)行了設(shè)計(jì)計(jì)算。根據(jù)物料的運(yùn)輸要求，自動(dòng)送料裝置采用了運(yùn)輸鏈和槽輪機(jī)構(gòu)運(yùn)輸方式，由此可對(duì)送料裝置的速度進(jìn)行調(diào)節(jié)，以實(shí)現(xiàn)速度的可調(diào)性。同時(shí)，由于鏈?zhǔn)捷斔蜋C(jī)是常見(jiàn)的連續(xù)動(dòng)作運(yùn)輸設(shè)備,其輸送能力大、調(diào)度組織簡(jiǎn)單、維護(hù)方便、營(yíng)運(yùn)費(fèi)用低,此外它還具有結(jié)構(gòu)簡(jiǎn)單、運(yùn)轉(zhuǎn)平穩(wěn)可靠、運(yùn)行阻力小、耗電量低、運(yùn)輸距離大，容易實(shí)現(xiàn)自動(dòng)化等特點(diǎn)。而且，由于槽輪機(jī)構(gòu)具有間歇性的運(yùn)動(dòng)，因此可達(dá)到?jīng)_孔自動(dòng)送料的要求。槽輪機(jī)構(gòu)是一種步進(jìn)間歇運(yùn)動(dòng)機(jī)構(gòu)，由于結(jié)構(gòu)簡(jiǎn)單、制造容易、工作可靠，能準(zhǔn)確地控制轉(zhuǎn)角，機(jī)械效率高，所以在
