旋轉(zhuǎn)鉆床工作臺(tái)的設(shè)計(jì)

1、12012屆本科畢業(yè)論文（設(shè)計(jì)）屆本科畢業(yè)論文（設(shè)計(jì)）題目：旋轉(zhuǎn)鉆床工作臺(tái)的設(shè)計(jì)題目：旋轉(zhuǎn)鉆床工作臺(tái)的設(shè)計(jì)摘要摘要在機(jī)械加工行業(yè)中，旋轉(zhuǎn)鉆床工作臺(tái)使用量很大，為了提高加工效率，保證加工精度，必須對(duì)鉆床工作臺(tái)進(jìn)行數(shù)控化改進(jìn)。本文對(duì)傳統(tǒng)鉆床工作臺(tái)存在的不能很好的在圓周方向上鉆孔問題，設(shè)計(jì)了一款立式鉆床旋轉(zhuǎn)工作臺(tái)。本文確定數(shù)控鉆床工作臺(tái)整體結(jié)構(gòu)設(shè)計(jì)方案，對(duì)機(jī)械部分對(duì)圓周方向上旋轉(zhuǎn)，x、y方向上平移做了重點(diǎn)設(shè)計(jì)。對(duì)控制系統(tǒng)部分，本文闡述了用單片
