77、t;　　機(jī)械手主要由手部和運(yùn)動(dòng)機(jī)構(gòu)組成。手部是用來(lái)抓持工件（或工具）的部件，根據(jù)被抓持物件的形狀、尺寸、重量、材料和作業(yè)要求而有有多種結(jié)構(gòu)形式，如加持型、托持型和吸附型等。運(yùn)動(dòng)機(jī)構(gòu)，使手部完成各種轉(zhuǎn)動(dòng)（擺動(dòng)）、移動(dòng)或復(fù)合運(yùn)動(dòng)來(lái)實(shí)現(xiàn)規(guī)定的動(dòng)作，改變被抓持物件的位置和姿勢(shì)。</p><p>　　機(jī)械手是在自動(dòng)化生產(chǎn)過(guò)程中使用的一種具有抓取和移動(dòng)工件功能的自動(dòng)化裝置，它是在機(jī)械化，自動(dòng)化生產(chǎn)過(guò)程中發(fā)展起來(lái)的一種新型裝置

78、。近年來(lái)，隨著電子技術(shù)特別是電子計(jì)算機(jī)的廣泛應(yīng)用，機(jī)器人的研制和生產(chǎn)已成為高技術(shù)領(lǐng)域內(nèi)迅速發(fā)展起來(lái)的一門新興技術(shù)，它更加促進(jìn)了機(jī)械手的發(fā)展，使得經(jīng)銷商能更好地實(shí)現(xiàn)與機(jī)械化和自動(dòng)化的有機(jī)結(jié)合。機(jī)械手能代替人類完成危險(xiǎn)、重復(fù)枯燥的工作，減輕人類勞動(dòng)強(qiáng)度，提高勞動(dòng)生產(chǎn)力。機(jī)械手越來(lái)越得到了廣泛的應(yīng)用，在機(jī)械行業(yè)中它可用于零部件的組裝，加工工件的搬運(yùn)、裝卸，特別是在自動(dòng)化數(shù)控機(jī)床、組合機(jī)床上使用更普遍。目前，機(jī)械手已發(fā)展成為柔性制造系統(tǒng)FMS和
