電(dian)磁(ci)振動上供(gong)料器的工(gong)作過(guo)程：

是(shi)由(you)于電(dian)磁鐵的吸引和(he)支承(cheng)彈簧的反向復位作用(yong),使(shi)料槽產生高(gao)速(su)高(gao)頻(pin)(50---100次/秒(miao)),微(wei)幅(fu)(0.5---1mm)振(zhen)動(dong)(dong),使(shi)工件逐(zhu)步(bu)(bu)向高(gao)處移動(dong)(dong).當(dang)(dang)I=0時(shi)(shi),料槽在支承(cheng)彈簧作用(yong)下(xia)(xia)向右上(shang)方復位,工件依靠它與軌(gui)道(dao)的磨擦而隨軌(gui)道(dao)向右上(shang)方運(yun)動(dong)(dong),并逐(zhu)步(bu)(bu)被加速(su).當(dang)(dang)I>0時(shi)(shi),料槽在電(dian)磁鐵的吸引下(xia)(xia)向左下(xia)(xia)方運(yun)動(dong)(dong),工件由(you)于慣(guan)性作用(yong)而脫(tuo)離軌(gui)道(dao),繼續(xu)向右上(shang)方運(yun)動(dong)(dong)(滑(hua)移或跳(tiao)躍),再經(jing)過光纖放大器的光電(dian)轉(zhuan)換作用(yong),經(jing)集成(cheng)線(xian)路模擬轉(zhuan)換至下(xia)(xia)一循環(huan),周而復始,工件在軌(gui)道(dao)上(shang)作由(you)低(di)到(dao)高(gao)的運(yun)動(dong)(dong)。
