精密振動盤動(dong)(dong)(dong)(dong)(dong)盤料(liao)斗(dou)下(xia)面有個脈(mo)沖(chong)電(dian)磁(ci)鐵，可以使料(liao)斗(dou)作(zuo)(zuo)垂直方向振(zhen)動(dong)(dong)(dong)(dong)(dong)，由傾斜的彈(dan)簧片帶動(dong)(dong)(dong)(dong)(dong)料(liao)斗(dou)繞其(qi)垂直軸做扭擺振(zhen)動(dong)(dong)(dong)(dong)(dong)。料(liao)斗(dou)內(nei)零件(jian)，由于受到(dao)這種振(zhen)動(dong)(dong)(dong)(dong)(dong)而(er)沿螺旋軌道上升。在上升的過程中經過一系(xi)列(lie)軌道的篩選(xuan)或者(zhe)姿(zi)態變化，零件(jian)能(neng)夠按照組(zu)裝(zhuang)(zhuang)或者(zhe)加(jia)工(gong)的要求呈統一狀(zhuang)態自動(dong)(dong)(dong)(dong)(dong)進入(ru)組(zu)裝(zhuang)(zhuang)或者(zhe)加(jia)工(gong)位置(zhi)。 其(qi)工(gong)作(zuo)(zuo)目(mu)的是通(tong)過振(zhen)動(dong)(dong)(dong)(dong)(dong)將(jiang)無序工(gong)件(jian)自動(dong)(dong)(dong)(dong)(dong)有序定向排列(lie)整齊、準確地(di)輸送到(dao)下(xia)道工(gong)序。
