分析鋸條磨齒機在電氣部分改造方案
(1)制(zhi)作電箱:使操(cao)(cao)作者(zhe)通過(guo)操(cao)(cao)作電箱控制(zhi)刀(dao)架轉臺轉位,從而使齒(chi)盤轉過(guo)相應角(jiao)度,并對(dui)齒(chi)盤進行加工(gong)。 ??
(2)電箱功(gong)能(neng):按(an)下自復位式按(an)鈕(niu),轉臺松開,轉過固定角度后鎖(suo)緊,即(ji)完成(cheng)轉位。如圖5所示。?
(3)轉(zhuan)(zhuan)(zhuan)(zhuan)臺(tai)控(kong)(kong)制(zhi)(zhi)過(guo)(guo)程簡(jian)介:轉(zhuan)(zhuan)(zhuan)(zhuan)臺(tai)的(de)控(kong)(kong)制(zhi)(zhi)機構主要包(bao)含松(song)(song)(song)開(kai)、鎖緊(jin)電(dian)(dian)磁閥(fa)(fa),鎖緊(jin)、松(song)(song)(song)開(kai)到(dao)(dao)位(wei)檢(jian)測(ce)開(kai)關(guan)。在控(kong)(kong)制(zhi)(zhi)過(guo)(guo)程中PLC接(jie)收控(kong)(kong)制(zhi)(zhi)信號(hao)(hao)并輸(shu)出,控(kong)(kong)制(zhi)(zhi)轉(zhuan)(zhuan)(zhuan)(zhuan)臺(tai)執(zhi)行(xing)相應的(de)動(dong)作(zuo)。按(an)下(xia)按(an)鈕(niu),PLC接(jie)收到(dao)(dao)轉(zhuan)(zhuan)(zhuan)(zhuan)位(wei)信號(hao)(hao)后(hou),PLC輸(shu)出松(song)(song)(song)開(kai)信號(hao)(hao),松(song)(song)(song)開(kai)電(dian)(dian)磁閥(fa)(fa)得(de)電(dian)(dian),轉(zhuan)(zhuan)(zhuan)(zhuan)臺(tai)松(song)(song)(song)開(kai)。PLC收到(dao)(dao)松(song)(song)(song)開(kai)反饋信號(hao)(hao)后(hou),經延時輸(shu)出正轉(zhuan)(zhuan)(zhuan)(zhuan)信號(hao)(hao),正轉(zhuan)(zhuan)(zhuan)(zhuan)電(dian)(dian)磁閥(fa)(fa)得(de)電(dian)(dian),轉(zhuan)(zhuan)(zhuan)(zhuan)臺(tai)正轉(zhuan)(zhuan)(zhuan)(zhuan)。轉(zhuan)(zhuan)(zhuan)(zhuan)到(dao)(dao)一(yi)個(ge)工位(wei)角度(du)后(hou),到(dao)(dao)位(wei)檢(jian)測(ce)開(kai)關(guan)輸(shu)出,PLC收到(dao)(dao)到(dao)(dao)位(wei)信號(hao)(hao)后(hou),經延時輸(shu)出鎖緊(jin)信號(hao)(hao),鎖緊(jin)電(dian)(dian)磁閥(fa)(fa)得(de)電(dian)(dian),轉(zhuan)(zhuan)(zhuan)(zhuan)臺(tai)鎖緊(jin),轉(zhuan)(zhuan)(zhuan)(zhuan)位(wei)過(guo)(guo)程完成(cheng)。?
(4)砂輪(lun)修(xiu)整(zheng)器部分:使用伺服(fu)(fu)驅動(dong)器的位置模式實現砂輪(lun)修(xiu)整(zheng)器的動(dong)作,位置命令由內部寄存(cun)器提供,命令值通過伺服(fu)(fu)驅動(dong)器參數設定,通過觸發(fa)信號(hao)(hao)觸發(fa)動(dong)作。PLC通過DI信號(hao)(hao)選(xuan)擇(ze)寄存(cun)器編(bian)號(hao)(hao)和觸發(fa)相應動(dong)作,實現砂輪(lun)修(xiu)整(zheng)器的往復運動(dong)。

2:平面(mian)磨床(chuang)砂輪
①所選砂輪須能承(cheng)受周轉(zhuan)速2000m/min以(yi)上。②禁止使用有破損之(zhi)砂輪。③新砂輪裝上法蘭(lan)必須做平衡(heng)。④進(jin)(jin)行正(zheng)式磨削前,砂輪需(xu)空轉(zhuan)5分鐘。⑤zui大進(jin)(jin)刀量行程800mm以(yi)下磨床為0.03mm,800mm以(yi)上磨床為0.05mm。
3:平面磨床主軸(zhou)
①安裝(zhuang)砂(sha)輪(lun)前須確(que)定主(zhu)(zhu)軸為順(shun)時(shi)針方向旋轉。②開(kai)機時(shi),須先(xian)開(kai)主(zhu)(zhu)軸后開(kai)沖水。
