車床件主電路的分析

車床件主電路的分析 數控車床主電路中共有三台電動機：主軸電動機
，用以實現主軸旋轉和進給運動。冷卻泵電動機。溜板快速移動電動機。均為三相異步電動機，容量均小於10kW，quanbucaiyongquanyazhijieqidongjieyoujiaoliujiechuqikongzhidanxiangxuanzhuan。zhuzhoudiandongjiyouqidonganniutingzhianniuhejiechuqigouchengdiandongjidanxianglianxuyunzhuankongzhidianlu。zhuzhoudezhengfanzhuanyoumocaliheqigaibianchuandonglaishixian。 冷leng卻que泵beng電dian動dong機ji是shi在zai主zhu軸zhou電dian動dong機ji起qi動dong之zhi後hou，扳ban動dong冷leng卻que泵beng控kong製zhi開kai關guan來lai控kong製zhi接jie觸chu器qi的de通tong斷duan，實shi現xian冷leng卻que泵beng電dian動dong機ji的de起qi動dong與yu停ting止zhi。由you於yu開kai關guan具ju有you定ding位wei功gong能neng，故gu不bu需xu自zi鎖suo。溜liu板ban快kuai速su移yi動dong電dian動dong機ji由you裝zhuang在zai溜liu板ban箱xiang上shang的de快kuai慢man速su進jin給gei手shou柄bing內nei的de快kuai速su移yi動dong按an鈕niu來lai控kong製zhi接jie觸chu器qi
