螺栓與扳手大小怎么換算
一般(ban)是(shi)(shi)(shi)螺(luo)(luo)(luo)栓(shuan)(shuan)的(de)(de)直(zhi)徑(jing)乘(cheng)以1.5倍就是(shi)(shi)(shi)呆(dai)口、梅(mei)花的(de)(de)尺(chi)寸(cun)(cun)。內(nei)六(liu)角(jiao)扳(ban)(ban)(ban)手(shou)(shou)(shou)一般(ban)是(shi)(shi)(shi)螺(luo)(luo)(luo)栓(shuan)(shuan)的(de)(de)直(zhi)徑(jing)減去2。所(suo)有的(de)(de)扳(ban)(ban)(ban)手(shou)(shou)(shou),包括(kuo)開口扳(ban)(ban)(ban)手(shou)(shou)(shou)、內(nei)六(liu)角(jiao)扳(ban)(ban)(ban)手(shou)(shou)(shou)、梅(mei)花扳(ban)(ban)(ban)手(shou)(shou)(shou)、套(tao)筒扳(ban)(ban)(ban)手(shou)(shou)(shou)等,其尺(chi)寸(cun)(cun)都是(shi)(shi)(shi)指(zhi)螺(luo)(luo)(luo)栓(shuan)(shuan)頭部(bu)對(dui)邊的(de)(de)寬度尺(chi)寸(cun)(cun),而螺(luo)(luo)(luo)栓(shuan)(shuan)的(de)(de)規格是(shi)(shi)(shi)指(zhi)螺(luo)(luo)(luo)紋的(de)(de)公(gong)稱直(zhi)徑(jing)。螺(luo)(luo)(luo)栓(shuan)(shuan)和扳(ban)(ban)(ban)手(shou)(shou)(shou)的(de)(de)標準有很多,換算(suan)方法(fa)也不同,例如(ru),M10的(de)(de)外(wai)六(liu)角(jiao)螺(luo)(luo)(luo)栓(shuan)(shuan),其對(dui)邊寬度為16mm,就選用16的(de)(de)開口扳(ban)(ban)(ban)手(shou)(shou)(shou)或(huo)梅(mei)花扳(ban)(ban)(ban)手(shou)(shou)(shou)。又如(ru)GB/70-85內(nei)六(liu)角(jiao)螺(luo)(luo)(luo)栓(shuan)(shuan),M10的(de)(de)內(nei)六(liu)角(jiao)螺(luo)(luo)(luo)栓(shuan)(shuan)的(de)(de)對(dui)邊尺(chi)寸(cun)(cun)為8mm,則選用8mm的(de)(de)內(nei)六(liu)角(jiao)扳(ban)(ban)(ban)手(shou)(shou)(shou)。
1、計(ji)算標準螺栓螺母尺(chi)寸(扳手尺(chi)寸)的(de)經驗(yan)公式(shi)(采(cai)用(yong)分(fen)數形式(shi)):
標準螺(luo)(luo)(luo)栓螺(luo)(luo)(luo)母尺(chi)(chi)寸(cun)(cun)(扳手尺(chi)(chi)寸(cun)(cun))=(螺(luo)(luo)(luo)栓螺(luo)(luo)(luo)紋尺(chi)(chi)寸(cun)(cun)分子(zi)×3)÷(螺(luo)(luo)(luo)栓螺(luo)(luo)(luo)紋尺(chi)(chi)寸(cun)(cun)分子(zi)×2)
例如(ru):1/2英(ying)寸(cun)螺(luo)紋的(de)標(biao)準螺(luo)栓對應的(de)扳手尺寸(cun)=(1×3)÷(2×2)英(ying)寸(cun)=3/4英(ying)寸(cun)
2、計算加(jia)重螺栓螺母尺寸(扳(ban)手尺寸)的經驗公式(shi)(采用分數形(xing)式(shi)):
加重螺栓螺母尺(chi)(chi)寸(扳(ban)手(shou)尺(chi)(chi)寸)=標準螺栓螺母尺(chi)(chi)寸1/8。
例如:1/2英(ying)寸(cun)螺紋的(de)加重(zhong)螺栓對應的(de)扳手(shou)尺寸(cun)=(1×3)÷(2×2)英(ying)寸(cun)1/8=7/8英(ying)寸(cun)。
