電磁振動上(shang)供料(liao)器的工作過程：

是由于(yu)(yu)電磁鐵(tie)的吸引和支承彈簧(huang)的反向(xiang)(xiang)復(fu)(fu)位作(zuo)用(yong)(yong),使(shi)料槽(cao)(cao)產生高(gao)速高(gao)頻(50---100次/秒),微幅(0.5---1mm)振動,使(shi)工(gong)(gong)件(jian)逐步(bu)向(xiang)(xiang)高(gao)處移(yi)動.當I=0時,料槽(cao)(cao)在支承彈簧(huang)作(zuo)用(yong)(yong)下向(xiang)(xiang)右上(shang)(shang)方復(fu)(fu)位,工(gong)(gong)件(jian)依靠它與軌(gui)(gui)道的磨擦而(er)隨軌(gui)(gui)道向(xiang)(xiang)右上(shang)(shang)方運動,并逐步(bu)被加速.當I>0時,料槽(cao)(cao)在電磁鐵(tie)的吸引下向(xiang)(xiang)左(zuo)下方運動,工(gong)(gong)件(jian)由于(yu)(yu)慣性作(zuo)用(yong)(yong)而(er)脫離軌(gui)(gui)道,繼續(xu)向(xiang)(xiang)右上(shang)(shang)方運動(滑移(yi)或跳躍(yue)),再經過光(guang)纖放大器的光(guang)電轉(zhuan)換(huan)作(zuo)用(yong)(yong),經集成線路模擬轉(zhuan)換(huan)至下一循環,周而(er)復(fu)(fu)始(shi),工(gong)(gong)件(jian)在軌(gui)(gui)道上(shang)(shang)作(zuo)由低到高(gao)的運動。
