1、天津職業(yè)技術(shù)師范大學(xué)本科生畢業(yè)設(shè)計(jì)移動(dòng)式磨拋機(jī)床柔性磨拋頭設(shè)計(jì)Flexiblegrindingheadofportablegrindingmachinedesign專業(yè)班級：機(jī)自0901學(xué)生姓名：指導(dǎo)教師：學(xué)院：機(jī)械工程學(xué)院2013年6月摘要隨著磨拋技術(shù)的提高，磨削技術(shù)已然成為提高工件表面加工質(zhì)量，加工精度以及表面粗糙度關(guān)鍵的表面后處理工藝。傳統(tǒng)的手工打磨不僅效率低，而且勞動(dòng)強(qiáng)度大，目前最常用的磨拋方式是砂輪磨拋和砂帶磨拋，傳統(tǒng)的砂輪或砂帶磨拋頭與機(jī)床的連接方式屬于剛性連接，沒有實(shí)現(xiàn)柔性。設(shè)計(jì)柔性磨拋頭可以在磨拋過程中起到減振緩沖作用，
2、這樣不僅可以保證加工時(shí)機(jī)構(gòu)的穩(wěn)定性而可以保證恒力磨削，從而保證了表面的加工質(zhì)量、加工精度以及表面粗糙度。本文針對飛機(jī)外殼等大型表面設(shè)計(jì)了砂帶柔性磨拋頭和砂輪柔性磨拋頭，設(shè)計(jì)過程如下：1.分別對砂帶、砂輪磨拋進(jìn)行簡單的理論概述；2.設(shè)計(jì)柔性磨拋頭的各重要構(gòu)件并且完成三維造型；3.對柔性機(jī)構(gòu)進(jìn)行方案的構(gòu)想和設(shè)計(jì)并且完成三維造型。砂輪磨拋和砂帶磨拋技術(shù)發(fā)展越來越廣泛，基本上所有的材料都可以用這兩種磨拋方式，它們受到人們越來越多的關(guān)注，對人們的生活也起著越來越重要的作用，所以本文設(shè)計(jì)了適用于移動(dòng)式磨拋機(jī)床的柔性磨拋頭具有很大的實(shí)用價(jià)值和經(jīng)濟(jì)效益
