為wei了le保bao證zheng直zhi線xian導dao軌gui正zheng常chang工gong作zuo，直zhi線xian導dao軌gui滑hua動dong表biao麵mian之zhi間jian應ying保bao持chi適shi當dang的de間jian隙xi，間jian隙xi過guo小xiao會hui增zeng大da摩mo擦ca力li，間jian隙xi過guo大da又you會hui降jiang低di導dao向xiang精jing度du。因yin此ci，調tiao整zheng直zhi線xian導dao軌gui間jian隙xi是shi確que保bao導dao軌gui正zheng常chang工gong作zuo和he維wei持chi導dao向xiang精jing度du的de重zhong要yao步bu驟zhou。以yi下xia是shi調tiao整zheng直zhi線xian導dao軌gui間jian隙xi的de幾ji種zhong常chang用yong方fang法fa：
1、鑲條：charuxiangtiaoyongyutiaozhengjuxingzhixiandaoguiyuyanweizhixiandaoguizhijiandecexi，baozhengzhixiandaoguibiaomiandezhengchangjiechu。yingjiangxiangtiaofangzhizaidaoguishoulijiaoxiaodeyice，quebaoqinenggoujunyunjiechudaoguibiaomian，shiyongtiaozhengluodingtuidongxiangtiaojinxingzongxiangyidong，yitiaozhengjianxi。
2、壓板調整：壓(ya)板(ban)用(yong)於(yu)進(jin)行(xing)調(tiao)節(jie)輔(fu)助(zhu)直(zhi)線(xian)導(dao)軌(gui)的(de)間(jian)隙(xi)，承(cheng)受(shou)傾(qing)覆(fu)力(li)矩(ju)，該(gai)結(jie)構(gou)主(zhu)要(yao)用(yong)於(yu)通(tong)過(guo)不(bu)同(tong)磨(mo)削(xue)或(huo)刮(gua)板(ban)表(biao)麵(mian)來(lai)調(tiao)整(zheng)工(gong)作(zuo)間(jian)隙(xi)。此(ci)外(wai)，還(hai)可(ke)以(yi)通(tong)過(guo)改(gai)變(bian)板(ban)和(he)連(lian)接(jie)表(biao)麵(mian)之(zhi)間(jian)的(de)間(jian)隔(ge)件(jian)的(de)厚(hou)度(du)來(lai)調(tiao)整(zheng)該(gai)間(jian)隙(xi)，墊(dian)圈(quan)是(shi)由(you)許(xu)多(duo)薄(bo)銅(tong)板(ban)堆(dui)在(zai)一(yi)起(qi)，並(bing)與(yu)錫(xi)焊(han)接(jie)在(zai)一(yi)邊(bian)。該(gai)方(fang)法(fa)比(bi)刮(gua)磨(mo)板(ban)更(geng)方(fang)便(bian)，但(dan)調(tiao)整(zheng)受(shou)到(dao)墊(dian)片(pian)厚(hou)度(du)的(de)限(xian)製(zhi)，降(jiang)低(di)了(le)接(jie)頭(tou)表(biao)麵(mian)的(de)接(jie)觸(chu)剛(gang)度(du)。
3、調整導軌滑塊預緊力：使(shi)用(yong)遊(you)標(biao)卡(ka)尺(chi)或(huo)外(wai)徑(jing)量(liang)規(gui)等(deng)專(zhuan)業(ye)工(gong)具(ju)，測(ce)量(liang)導(dao)軌(gui)上(shang)下(xia)兩(liang)側(ce)的(de)間(jian)隙(xi)，通(tong)過(guo)調(tiao)整(zheng)導(dao)軌(gui)滑(hua)塊(kuai)的(de)預(yu)緊(jin)力(li)，使(shi)其(qi)能(neng)夠(gou)沿(yan)著(zhe)導(dao)軌(gui)運(yun)動(dong)時(shi)緊(jin)密(mi)貼(tie)合(he)在(zai)導(dao)軌(gui)表(biao)麵(mian)，還(hai)可(ke)以(yi)通(tong)過(guo)調(tiao)整(zheng)滑(hua)塊(kuai)上(shang)的(de)螺(luo)釘(ding)或(huo)螺(luo)母(mu)來(lai)實(shi)現(xian)。
