繞線(xian)機影響線(xian)圈尺寸的原(yuan)因

線圈繞(rao)制時(shi)，導線線規和匝間間隙決議了(le)線圈各尺(chi)寸(cun)，控(kong)制線圈尺(chi)寸(cun)的前提條(tiao)件就是找出影響線圈匝問(wen)問(wen)隙的要(yao)素，這(zhe)也(ye)是控(kong)制線圈尺(chi)寸(cun)的必要(yao)條(tiao)件。

1、線圈尺寸問題

   近期運用(yong)立式繞(rao)線機繞(rao)制(zhi)單(dan)餅式線圈時，控制(zhi)繞(rao)線機的(de)拉力的(de)磁粉離合器的(de)電流值設(she)定為(wei)0.45A，泰州雙工(gong)(gong)位繞(rao)線機，線圈繞(rao)制(zhi)完(wan)成后B端(duan)尺寸(cun)均偏大(da)，超收工(gong)(gong)藝請求范圍。

2、線圈(quan)尺寸(cun)問題緣由剖析

   當繞線(xian)(xian)(xian)(xian)(xian)機拉(la)力相關(guan)電流(liu)值(zhi)設定(ding)為0.45A時，繞制過(guo)程(cheng)中(zhong)(zhong)發(fa)現(xian)，由于(yu)拉(la)力太小，招致線(xian)(xian)(xian)(xian)(xian)盤(pan)上的(de)導(dao)線(xian)(xian)(xian)(xian)(xian)受(shou)(shou)力不平(ping)(ping)均，在線(xian)(xian)(xian)(xian)(xian)盤(pan)轉動(dong)的(de)時分呈現(xian)由于(yu)慣性線(xian)(xian)(xian)(xian)(xian)盤(pan)空轉的(de)現(xian)象(xiang)，導(dao)線(xian)(xian)(xian)(xian)(xian)脫出(chu)較(jiao)多，招致在線(xian)(xian)(xian)(xian)(xian)盤(pan)與導(dao)線(xian)(xian)(xian)(xian)(xian)夾緊器之間的(de)導(dao)線(xian)(xian)(xian)(xian)(xian)不是理想的(de)程(cheng)度狀態(tai)，而是下垂(chui)出(chu)一(yi)定(ding)弧度，因此導(dao)線(xian)(xian)(xian)(xian)(xian)在繞制過(guo)程(cheng)中(zhong)(zhong)受(shou)(shou)力不平(ping)(ping)均，且繞制完成的(de)線(xian)(xian)(xian)(xian)(xian)餅緊實度不夠，因而招致線(xian)(xian)(xian)(xian)(xian)圈B尺寸大(da)于(yu)技術請(qing)求值(zhi)。

3、繞線機(ji)拉力與線圈尺(chi)寸(cun)關系(xi)剖析(xi)

   (1)恰當(dang)增大繞線(xian)機拉(la)力對線(xian)圈的(de)影(ying)響。在線(xian)圈繞制過程中，逐步增大拉(la)力，將立式繞線(xian)機的(de)拉(la)力相關電流值調整(zheng)為0.46A，線(xian)圈松(song)弛。尺寸(cun)偏大的(de)現(xian)象有所(suo)改善(shan)，但(dan)是依然不契合請求。

   繼(ji)續加大立式繞線(xian)(xian)(xian)機的拉力(li)相(xiang)關電流值調整到0.47A，線(xian)(xian)(xian)圈尺寸契合請(qing)求(qiu)，且線(xian)(xian)(xian)圈緊(jin)實，在A ，B端(duan)沒有明顯問隙，4個角也沒有緊(jin)繃或上翹的現象(xiang)，導線(xian)(xian)(xian)線(xian)(xian)(xian)規變化契合請(qing)求(qiu)。

   (2)繞(rao)(rao)線(xian)(xian)機拉(la)力過(guo)大對線(xian)(xian)圈的(de)影(ying)響。繼續增大立式繞(rao)(rao)線(xian)(xian)機拉(la)力相關電流值到0.51A時，雙(shuang)工位繞(rao)(rao)線(xian)(xian)機生(sheng)產廠家(jia)，線(xian)(xian)圈在繞(rao)(rao)制過(guo)程中，4個(ge)角(jiao)受力過(guo)重，有(you)上翹現(xian)象，雙(shuang)工位繞(rao)(rao)線(xian)(xian)機廠家(jia)，繞(rao)(rao)制完成后，導線(xian)(xian)問無明顯問隙，導線(xian)(xian)線(xian)(xian)規沒有(you)急劇減小(xiao)，但(dan)是4個(ge)角(jiao)有(you)上翹現(xian)象，不契合技術請求。    

   由上述可知，當立式(shi)繞(rao)線(xian)機拉力(li)值過(guo)小(xiao)時，線(xian)圈(quan)繞(rao)制完成后(hou)，線(xian)圈(quan)小(xiao)緊實，導線(xian)問(wen)有問(wen)隙，且B端(duan)尺寸(cun)(cun)大(da)于技術請(qing)(qing)求值。恰當的增大(da)立式(shi)繞(rao)線(xian)機拉力(li)能夠(gou)減(jian)小(xiao)線(xian)餅B端(duan)尺寸(cun)(cun)，且小(xiao)影響導線(xian)線(xian)規，從(cong)而(er)改善B端(duan)尺寸(cun)(cun)偏大(da)的問(wen)題(ti)。但(dan)是當立式(shi)繞(rao)線(xian)機拉力(li)過(guo)大(da)，又會招致線(xian)圈(quan)小(xiao)契(qi)合技術請(qing)(qing)求。

   由此可(ke)見拉力與線(xian)圈尺寸緊(jin)密相關的，在線(xian)圈繞制(zhi)時，繞線(xian)機拉力要調整到對應的匹(pi)配(pei)值。

繞線機(ji)電機(ji)的常見故障及原因

首先是(shi)缺相(xiang)運行一般故障的(de)(de)表現(xian)現(xian)象是(shi)：電(dian)(dian)(dian)(dian)機(ji)(ji)不能起(qi)動(dong)，雙工位繞線(xian)機(ji)(ji)價格，即使空載能起(qi)動(dong)，轉速慢慢上升，有嗡(weng)嗡(weng)聲；電(dian)(dian)(dian)(dian)機(ji)(ji)冒(mao)煙發熱，并(bing)伴有燒焦味，造(zao)成的(de)(de)原因是(shi)以下幾種可(ke)能：供電(dian)(dian)(dian)(dian)回路(lu)熔絲(si)(si)回路(lu)接(jie)觸不良或受機(ji)(ji)械損(sun)傷(shang)(shang)，致使某相(xiang)熔絲(si)(si)熔斷、電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)供電(dian)(dian)(dian)(dian)回路(lu)三(san)相(xiang)熔絲(si)(si)規格不同(tong)，容量小(xiao)(xiao)的(de)(de)熔絲(si)(si)燒斷。應根據(ju)電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)功(gong)率(lv)大小(xiao)(xiao)，更換為規格相(xiang)同(tong)的(de)(de)熔絲(si)(si)、電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)供電(dian)(dian)(dian)(dian)回路(lu)中(zhong)的(de)(de)開關（隔(ge)離開關、膠(jiao)蓋(gai)開關等）及(ji)接(jie)觸的(de)(de)觸頭接(jie)觸不良（燒l傷(shang)(shang)或松脫）。修復并(bing)調整動(dong)、靜(jing)觸頭，使之接(jie)觸良好、電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)繞組(zu)連(lian)線(xian)間虛焊，導(dao)致接(jie)觸不良，認真檢查(cha)電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)繞組(zu)連(lian)接(jie)線(xian)并(bing)焊牢。

自(zi)動繞線機(ji)廠(chang)家(jia)是一個實時(shi)嵌入式系統。控制器的(de)(de)(de)時(shi)間(jian)要求（中(zhong)(zhong)斷(duan)響應(ying)時(shi)間(jian)）達(da)到(dao)50微秒，實時(shi)操作系統的(de)(de)(de)響應(ying)時(shi)間(jian)達(da)到(dao)幾十微秒。有(you)些功率還不夠(gou)，所(suo)以(yi)我不使用(yong)實時(shi)操作系統，而是使用(yong)傳(chuan)統的(de)(de)(de)主(zhu)(zhu)(zhu)循環加中(zhong)(zhong)斷(duan)功能。程序的(de)(de)(de)主(zhu)(zhu)(zhu)要流程主(zhu)(zhu)(zhu)函(han)數初始化后，進(jin)入主(zhu)(zhu)(zhu)循環。主(zhu)(zhu)(zhu)循環處理繞組，顯示(shi)刷新，鍵掃描，IO端(duan)(duan)口掃描，串行端(duan)(duan)口消息(xi)和(he)(he)定(ding)時(shi)器。程序的(de)(de)(de)中(zhong)(zhong)斷(duan)包括(kuo)繞線電機(ji)的(de)(de)(de)繞組捕(bu)獲(huo)定(ding)時(shi)器中(zhong)(zhong)斷(duan)，電機(ji)的(de)(de)(de)PWM脈沖定(ding)時(shi)器中(zhong)(zhong)斷(duan)，通(tong)用(yong)定(ding)時(shi)器中(zhong)(zhong)斷(duan)和(he)(he)串行端(duan)(duan)口中(zhong)(zhong)斷(duan)。
