一、沖擊鉆更換鉆頭的方法

沖(chong)擊鉆(zhan)(zhan)(zhan)(zhan)，又稱沖(chong)擊電(dian)(dian)鉆(zhan)(zhan)(zhan)(zhan)，是一種用于磚、砌塊(kuai)及輕質(zhi)墻等材料上鉆(zhan)(zhan)(zhan)(zhan)孔的電(dian)(dian)動(dong)工(gong)具，以(yi)旋(xuan)轉(zhuan)(zhuan)切削為主，兼(jian)有(you)依(yi)靠操作(zuo)者(zhe)推(tui)力(li)(li)生(sheng)產(chan)沖(chong)擊力(li)(li)的沖(chong)擊機構，以(yi)垂直往復運動(dong)依(yi)靠沖(chong)擊力(li)(li)進行鉆(zhan)(zhan)(zhan)(zhan)孔。使用沖(chong)擊鉆(zhan)(zhan)(zhan)(zhan)時，需要(yao)需要(yao)根(gen)據不同的作(zuo)業情(qing)況更(geng)(geng)換鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)，更(geng)(geng)換方法是：1、切斷電(dian)(dian)源，把沖(chong)擊鉆(zhan)(zhan)(zhan)(zhan)倒(dao)放(fang)在(zai)地上，鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)朝(chao)上。2、旋(xuan)開(kai)帶(dai)齒的轉(zhuan)(zhuan)環，拿(na)出(chu)沖(chong)擊鉆(zhan)(zhan)(zhan)(zhan)上的鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)，一般鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)部位有(you)可上下活動(dong)的塑(su)膠(jiao)圈，左手向下按住(zhu)鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)根(gen)部的塑(su)膠(jiao)圈，右手握住(zhu)鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)向上提即可取(qu)出(chu)。3、取(qu)出(chu)原(yuan)來的鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)后，把新的鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)插入沖(chong)擊鉆(zhan)(zhan)(zhan)(zhan)的正中間，再反著(zhu)轉(zhuan)(zhuan)動(dong)剛松開(kai)的轉(zhuan)(zhuan)環，讓(rang)它(ta)咬(yao)合(he)住(zhu)剛放(fang)進去(qu)的鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)，卡緊即可。4、檢查一下看看有(you)沒有(you)鎖牢固鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)，插上電(dian)(dian)源，把沖(chong)擊鉆(zhan)(zhan)(zhan)(zhan)朝(chao)下，開(kai)起電(dian)(dian)源試用一下，沒有(you)問題即可。

二、沖擊鉆鉆頭型號有幾種

購買沖擊鉆時，需要根據作業需求選擇合適型號的沖擊鉆，沖擊鉆的型號一般是以鉆頭直徑來區分的，市面上常見的有：6mm、8mmm、10mm、12mm、14mm、16mm、20mm、24mm、26mm、28mm等，不同型號的沖擊鉆在參數方面存在一定的差異，適合使用的場景也有所不同，主要根據作業對象及成孔直徑、加工材料、作業環境來選擇合適型號的沖擊鉆。除了型號以外，購買沖擊鉆時還要注意考慮功率、動力來源、充電還是插電、沖擊鉆品牌等因素。

三、沖擊鉆和電錘有什么區別

1、工(gong)(gong)作原理(li)不(bu)同：沖(chong)(chong)擊(ji)鉆(zhan)(zhan)主要(yao)依靠旋轉和沖(chong)(chong)擊(ji)來工(gong)(gong)作，單一(yi)的沖(chong)(chong)擊(ji)非常輕(qing)微，但可以(yi)產生連續的力；電(dian)錘則(ze)(ze)要(yao)依靠旋轉和捶(chui)打來工(gong)(gong)作，單個(ge)捶(chui)打力非常高(gao)，并有(you)較高(gao)的捶(chui)打頻率。2、適(shi)用(yong)對(dui)(dui)象不(bu)同：沖(chong)(chong)擊(ji)鉆(zhan)(zhan)主要(yao)適(shi)用(yong)于(yu)在木材、金屬、陶瓷(ci)和塑料上(shang)進行鉆(zhan)(zhan)孔(kong)，也可以(yi)對(dui)(dui)混凝(ning)土地板、墻壁、磚(zhuan)塊(kuai)、石料沖(chong)(chong)擊(ji)鉆(zhan)(zhan)孔(kong)；電(dian)錘則(ze)(ze)主要(yao)用(yong)于(yu)較硬的混凝(ning)土、石料、墻磚(zhuan)打孔(kong)等場所。3、特(te)點(dian)不(bu)同：沖(chong)(chong)擊(ji)鉆(zhan)(zhan)的用(yong)途廣泛、使(shi)用(yong)方便(bian)，但是沖(chong)(chong)擊(ji)鉆(zhan)(zhan)在使(shi)用(yong)時方向不(bu)易把(ba)握，容易操作失(shi)誤(wu)，造成開孔(kong)偏(pian)大(da)；加(jia)上(shang)鉆(zhan)(zhan)頭(tou)不(bu)鋒利(li)，使(shi)所開的孔(kong)不(bu)工(gong)(gong)整(zheng)，出現(xian)毛刺或裂紋；電(dian)錘的優點(dian)是效(xiao)率高(gao)，孔(kong)徑大(da)、鉆(zhan)(zhan)進深度(du)(du)長，缺點(dian)就是震動大(da)，對(dui)(dui)周(zhou)邊構筑物(wu)有(you)一(yi)定程度(du)(du)的破壞作用(yong)。

四、多功能沖擊鉆怎么使用

1、在(zai)鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)孔(kong)(kong)前，要(yao)先用鉛筆(bi)或粉筆(bi)在(zai)墻(qiang)上(shang)標出孔(kong)(kong)的(de)位置(zhi)，用中心(xin)(xin)沖(chong)(chong)子沖(chong)(chong)擊(ji)(ji)孔(kong)(kong)的(de)圓心(xin)(xin)。2、選擇筆(bi)直(zhi)、鋒利、無損(sun)、與(yu)孔(kong)(kong)徑相同(tong)的(de)沖(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)，打開沖(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)的(de)卡(ka)頭(tou)，將(jiang)鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)插到底，用卡(ka)頭(tou)鑰匙(chi)將(jiang)卡(ka)頭(tou)擰(ning)緊(jin)。3、選擇適當的(de)鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)速（孔(kong)(kong)徑大時(shi)用低(di)速，孔(kong)(kong)徑小時(shi)用高速），鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)堅硬的(de)墻(qiang)和(he)石(shi)頭(tou)時(shi)，要(yao)接通(tong)沖(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)的(de)沖(chong)(chong)擊(ji)(ji)附件。4、雙(shuang)手緊(jin)握沖(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)，將(jiang)鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)尖(jian)抵在(zai)中心(xin)(xin)沖(chong)(chong)子沖(chong)(chong)擊(ji)(ji)的(de)凹(ao)坑內，使(shi)鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)與(yu)墻(qiang)面成90°角，啟動沖(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)，朝著鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)孔(kong)(kong)方向均勻(yun)用力，并使(shi)鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)始終保(bao)持(chi)著與(yu)墻(qiang)面的(de)垂直(zhi)。5、鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)孔(kong)(kong)過程中，不時(shi)移出鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)以清除鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)屑，直(zhi)到鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)孔(kong)(kong)作業完成。
