螺栓與扳手大小怎么換算
一般是(shi)螺(luo)(luo)栓(shuan)(shuan)的(de)直(zhi)徑(jing)乘以(yi)1.5倍就(jiu)是(shi)呆口、梅(mei)花(hua)的(de)尺寸(cun)。內(nei)六角扳(ban)(ban)(ban)(ban)(ban)手(shou)(shou)一般是(shi)螺(luo)(luo)栓(shuan)(shuan)的(de)直(zhi)徑(jing)減去2。所有(you)的(de)扳(ban)(ban)(ban)(ban)(ban)手(shou)(shou),包括(kuo)開(kai)口扳(ban)(ban)(ban)(ban)(ban)手(shou)(shou)、內(nei)六角扳(ban)(ban)(ban)(ban)(ban)手(shou)(shou)、梅(mei)花(hua)扳(ban)(ban)(ban)(ban)(ban)手(shou)(shou)、套筒扳(ban)(ban)(ban)(ban)(ban)手(shou)(shou)等,其尺寸(cun)都(dou)是(shi)指螺(luo)(luo)栓(shuan)(shuan)頭部(bu)對邊(bian)(bian)(bian)的(de)寬度尺寸(cun),而螺(luo)(luo)栓(shuan)(shuan)的(de)規(gui)格是(shi)指螺(luo)(luo)紋(wen)的(de)公稱直(zhi)徑(jing)。螺(luo)(luo)栓(shuan)(shuan)和扳(ban)(ban)(ban)(ban)(ban)手(shou)(shou)的(de)標準(zhun)有(you)很多,換算方法也不同,例如(ru),M10的(de)外(wai)六角螺(luo)(luo)栓(shuan)(shuan),其對邊(bian)(bian)(bian)寬度為(wei)(wei)16mm,就(jiu)選(xuan)用16的(de)開(kai)口扳(ban)(ban)(ban)(ban)(ban)手(shou)(shou)或梅(mei)花(hua)扳(ban)(ban)(ban)(ban)(ban)手(shou)(shou)。又(you)如(ru)GB/70-85內(nei)六角螺(luo)(luo)栓(shuan)(shuan),M10的(de)內(nei)六角螺(luo)(luo)栓(shuan)(shuan)的(de)對邊(bian)(bian)(bian)尺寸(cun)為(wei)(wei)8mm,則選(xuan)用8mm的(de)內(nei)六角扳(ban)(ban)(ban)(ban)(ban)手(shou)(shou)。
1、計算標(biao)準(zhun)螺(luo)栓螺(luo)母尺(chi)寸(扳手尺(chi)寸)的經驗公式(采用分數形式):
標準螺(luo)(luo)栓螺(luo)(luo)母尺(chi)寸(cun)(cun)(扳手尺(chi)寸(cun)(cun))=(螺(luo)(luo)栓螺(luo)(luo)紋尺(chi)寸(cun)(cun)分子×3)÷(螺(luo)(luo)栓螺(luo)(luo)紋尺(chi)寸(cun)(cun)分子×2)
例如:1/2英寸(cun)(cun)螺紋(wen)的(de)(de)標準螺栓(shuan)對應的(de)(de)扳(ban)手尺寸(cun)(cun)=(1×3)÷(2×2)英寸(cun)(cun)=3/4英寸(cun)(cun)
2、計算加重螺(luo)栓(shuan)螺(luo)母尺寸(cun)(扳手尺寸(cun))的經(jing)驗公式(采用分數形式):
加重螺(luo)栓螺(luo)母(mu)尺(chi)(chi)寸(cun)(扳手(shou)尺(chi)(chi)寸(cun))=標(biao)準(zhun)螺(luo)栓螺(luo)母(mu)尺(chi)(chi)寸(cun)1/8。
例如:1/2英(ying)寸(cun)螺(luo)紋的加(jia)重(zhong)螺(luo)栓對應的扳手尺(chi)寸(cun)=(1×3)÷(2×2)英(ying)寸(cun)1/8=7/8英(ying)寸(cun)。
