無(wú)換刀機(jī)械手的結(jié)構(gòu)設(shè)計(jì)

1、摘要高速加工中心作為新時(shí)代數(shù)控機(jī)床的代表。已在機(jī)床領(lǐng)域廣泛使用。其高速、高效、高精等特點(diǎn)，贏得了市場(chǎng)的青睞，這些年來，國(guó)產(chǎn)加工中心技術(shù)發(fā)展得很快，國(guó)內(nèi)許多機(jī)床廠家都有了具有國(guó)際水平或接近國(guó)際水平的自主開發(fā)的加工中心機(jī)床。為了提高數(shù)控機(jī)床的機(jī)械加工精度和效率現(xiàn)大多數(shù)控機(jī)床和加工中心都配備刀庫(kù)以便一次裝卡就可完成多種工序的加工。常用刀庫(kù)有鏈?zhǔn)胶捅P式兩種刀庫(kù)容量有12、16、20、32、40等等。本文首先對(duì)16刀刀庫(kù)總體設(shè)計(jì)方案進(jìn)行闡述，闡述

2、其各部件的工作原理，然后就刀庫(kù)的結(jié)構(gòu)設(shè)計(jì)對(duì)各個(gè)部分進(jìn)行計(jì)算與設(shè)計(jì)。關(guān)鍵詞關(guān)鍵詞：加工中心，刀庫(kù)，液壓。目錄摘要.......................................................................................................................................................1ABSTRACT.....
