important; overflow-wrap: break-word !important;">
important; overflow-wrap: break-word !important;">手部空間的位置變化是通過(guò)沿著三個(gè)相互垂直的軸線移動(dòng)來(lái)實(shí)現(xiàn),常用于生產(chǎn)設(shè)備的上下料和高精度的裝配和檢測(cè)作業(yè)。一般直角坐標(biāo)型工業(yè)機(jī)器人的手臂可以垂直上下移動(dòng)(Z軸方向),并可以沿著滑架和橫梁上的導(dǎo)軌進(jìn)行水平二維平面的移動(dòng)(X、Y方向)。顯然直角坐標(biāo)型工業(yè)機(jī)器人有三個(gè)移動(dòng)關(guān)節(jié),即3個(gè)自由度。

important; overflow-wrap: break-word !important;">優(yōu)點(diǎn):
important; overflow-wrap: break-word !important;">·結(jié)構(gòu)簡(jiǎn)單;
important; overflow-wrap: break-word !important;">·編程容易,在X、Y、Z三個(gè)方向的運(yùn)
important; overflow-wrap: break-word !important;">動(dòng)沒(méi)有耦合,便于控制系統(tǒng)的設(shè)計(jì);
important; overflow-wrap: break-word !important;">·直線運(yùn)動(dòng)速度快,定位精度高,蔽障性能較好;
important; overflow-wrap: break-word !important;">
important; overflow-wrap: break-word !important;">缺點(diǎn)和問(wèn)題:
important; overflow-wrap: break-word !important;">·動(dòng)作范圍小,靈活性較差;
important; overflow-wrap: break-word !important;">·導(dǎo)軌結(jié)構(gòu)較復(fù)雜,維護(hù)比較困難,導(dǎo)軌暴露面大,不如轉(zhuǎn)動(dòng)關(guān)節(jié)密封性好;
important; overflow-wrap: break-word !important;">·結(jié)構(gòu)尺寸較大,占地面積較大;
important; overflow-wrap: break-word !important;">·移動(dòng)部分慣量較大,增加了對(duì)驅(qū)動(dòng)性能的要求;
