繞線機廠家的自動繞線機的排線(xian)精(jing)度與(yu)線(xian)圈(quan)(quan)層(ceng)面(mian)形狀(zhuang)控(kong)制(zhi),與(yu)主軸轉速控(kong)制(zhi)精(jing)度自動繞線(xian)機(ji)(ji)(ji)排線(xian)機(ji)(ji)(ji)構(gou)的運(yun)動精(jing)度和進線(xian)張(zhang)力等(deng)諸(zhu)多因素有關。繞線(xian)機(ji)(ji)(ji)廠家用(yong)細線(xian)線(xian)圈(quan)(quan)繞制(zhi)機(ji)(ji)(ji)的設計和調試實例,線(xian)機(ji)(ji)(ji)排線(xian)機(ji)(ji)(ji)構(gou)的結構(gou)、運(yun)動方式及控(kong)制(zhi)、線(xian)圈(quan)(quan)層(ceng)面(mian)形狀(zhuang)和層(ceng)面(mian)質量(liang)的影響作了分析。
繞(rao)(rao)圈(quan)的工藝要(yao)求繞(rao)(rao)圈(quan)骨(gu)(gu)架(jia)(jia),由兩端擋板、長(chang)方形的中空心柱(zhu)和接線插頭組成(cheng),對繞(rao)(rao)制在骨(gu)(gu)架(jia)(jia)上(shang)線圈(quan)的要(yao)求是:總成(cheng)后(hou)的層面(mian)不能形成(cheng)鼓(gu)型面(mian)或凹型面(mian),單面(mian)的線要(yao)排列(lie)整齊、均勻,不能有疊繞(rao)(rao)現象。
細線(xian)繞線(xian)機的(de)(de)基(ji)本組成與(yu)普通無棱式繞線(xian)機結構相(xiang)似(si),繞線(xian)機排線(xian)進(jin)給機構的(de)(de)驅(qu)(qu)動(dong)(dong)通常(chang)采用步(bu)(bu)(bu)進(jin)電動(dong)(dong)機作為基(ji)驅(qu)(qu)動(dong)(dong)源(yuan),可(ke)(ke)采用經(jing)聯軸器驅(qu)(qu)動(dong)(dong)滾(gun)珠(zhu)絲杠(gang)旋(xuan)轉或采用步(bu)(bu)(bu)進(jin)電動(dong)(dong)機經(jing)同步(bu)(bu)(bu)齒型帶(dai)驅(qu)(qu)動(dong)(dong)滾(gun)珠(zhu)絲杠(gang)旋(xuan)轉的(de)(de)兩(liang)種形式。采用由(you)步(bu)(bu)(bu)進(jin)電動(dong)(dong)機經(jing)同步(bu)(bu)(bu)齒型帶(dai)驅(qu)(qu)動(dong)(dong)滾(gun)珠(zhu)絲杠(gang)的(de)(de)形式,由(you)于在步(bu)(bu)(bu)進(jin)電動(dong)(dong)機軸與(yu)滾(gun)珠(zhu)絲杠(gang)之間采用柔性連(lian)接,對步(bu)(bu)(bu)進(jin)電動(dong)(dong)機座定(ding)位面的(de)(de)要(yao)求和(he)滾(gun)珠(zhu)絲杠(gang)與(yu)導向桿件的(de)(de)裝配要(yao)求可(ke)(ke)相(xiang) 應降低,使箱體孔加工(gong)容易,運動(dong)(dong)更加順暢。
在(zai)(zai)線圈繞(rao)制(zhi)(zhi)過(guo)程中,欲(yu)使值保持(chi)不(bu)變(bian)(bian),則(ze)與之(zhi)間的(de)速比(bi)就(jiu)必須(xu)隨而變(bian)(bian)化。由主軸轉(zhuan)速和繞(rao)制(zhi)(zhi)層面(mian)尺寸決定(ding),在(zai)(zai)穩定(ding)運行(xing)時保持(chi)不(bu)變(bian)(bian),因(yin)在(zai)(zai)換(huan)向(xiang)過(guo)渡過(guo)程中發(fa)(fa)生(sheng)變(bian)(bian)化,使在(zai)(zai)換(huan)向(xiang)過(guo)渡過(guo)程中發(fa)(fa)生(sheng)變(bian)(bian)化,因(yin)此,排線機構的(de)換(huan)向(xiang)控制(zhi)(zhi)就(jiu)成為控制(zhi)(zhi)繞(rao)制(zhi)(zhi)層面(mian)品質的(de)關鍵(jian)問題。
線圈(quan)層與層之間(jian)的繞(rao)(rao)組是相互疊壓(ya)的,即(ji)在一匝上有兩(liang)次(ci)疊壓(ya),大(da)螺(luo)距卷(juan)繞(rao)(rao)時(shi),線與線的疊壓(ya)容易(yi)通過(guo),小(xiao)螺(luo)距時(shi),進線張力過(guo)大(da)時(shi)易(yi)形成(cheng)堆疊現(xian)象,換向(xiang)時(shi),從正穩態值降至,再從升至負穩態值,這一過(guo)程(cheng)(cheng)的運行規律和(he)角位移值應(ying)換向(xiang)平穩,同(tong)層卷(juan)繞(rao)(rao)圈(quan)不疊繞(rao)(rao),要(yao)控制排線電動機的過(guo)渡過(guo)程(cheng)(cheng)時(shi)間(jian),而這一過(guo)程(cheng)(cheng)是通過(guo)軟件控制步進電動機實現(xian)的。
