一、沖擊鉆更換鉆頭的方法

沖(chong)擊(ji)鉆(zhan)(zhan)，又稱沖(chong)擊(ji)電鉆(zhan)(zhan)，是(shi)一(yi)種用于磚、砌塊及輕質墻等材料上(shang)(shang)鉆(zhan)(zhan)孔的(de)(de)電動工具，以旋轉(zhuan)切削為主(zhu)，兼有依靠操(cao)作者(zhe)推力生產沖(chong)擊(ji)力的(de)(de)沖(chong)擊(ji)機構(gou)，以垂直往復運動依靠沖(chong)擊(ji)力進(jin)行鉆(zhan)(zhan)孔。使用沖(chong)擊(ji)鉆(zhan)(zhan)時，需(xu)要(yao)需(xu)要(yao)根(gen)據不同(tong)的(de)(de)作業情況更(geng)換鉆(zhan)(zhan)頭，更(geng)換方法是(shi)：1、切斷電源(yuan)，把(ba)沖(chong)擊(ji)鉆(zhan)(zhan)倒放在地上(shang)(shang)，鉆(zhan)(zhan)頭朝(chao)上(shang)(shang)。2、旋開帶齒的(de)(de)轉(zhuan)環，拿出(chu)沖(chong)擊(ji)鉆(zhan)(zhan)上(shang)(shang)的(de)(de)鉆(zhan)(zhan)頭，一(yi)般(ban)鉆(zhan)(zhan)頭部(bu)位有可(ke)上(shang)(shang)下活(huo)動的(de)(de)塑(su)膠圈，左手(shou)向(xiang)下按住(zhu)鉆(zhan)(zhan)頭根(gen)部(bu)的(de)(de)塑(su)膠圈，右手(shou)握住(zhu)鉆(zhan)(zhan)頭向(xiang)上(shang)(shang)提即(ji)(ji)(ji)可(ke)取出(chu)。3、取出(chu)原來的(de)(de)鉆(zhan)(zhan)頭后，把(ba)新的(de)(de)鉆(zhan)(zhan)頭插入沖(chong)擊(ji)鉆(zhan)(zhan)的(de)(de)正中間，再(zai)反著轉(zhuan)動剛松開的(de)(de)轉(zhuan)環，讓它咬合住(zhu)剛放進(jin)去的(de)(de)鉆(zhan)(zhan)頭，卡緊即(ji)(ji)(ji)可(ke)。4、檢查(cha)一(yi)下看(kan)看(kan)有沒有鎖(suo)牢固鉆(zhan)(zhan)頭，插上(shang)(shang)電源(yuan)，把(ba)沖(chong)擊(ji)鉆(zhan)(zhan)朝(chao)下，開起電源(yuan)試用一(yi)下，沒有問題(ti)即(ji)(ji)(ji)可(ke)。

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、工作(zuo)(zuo)原理不(bu)同(tong)：沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)主要(yao)依(yi)靠旋轉和沖(chong)(chong)(chong)擊(ji)來工作(zuo)(zuo)，單一的沖(chong)(chong)(chong)擊(ji)非(fei)常輕微(wei)，但可(ke)(ke)以產生連(lian)續的力；電錘(chui)則要(yao)依(yi)靠旋轉和捶打(da)來工作(zuo)(zuo)，單個(ge)捶打(da)力非(fei)常高，并有(you)較高的捶打(da)頻率。2、適用(yong)(yong)(yong)對(dui)象(xiang)不(bu)同(tong)：沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)主要(yao)適用(yong)(yong)(yong)于在木材、金(jin)屬、陶瓷和塑(su)料上(shang)進行鉆(zhan)(zhan)孔(kong)，也可(ke)(ke)以對(dui)混凝(ning)(ning)土地(di)板(ban)、墻(qiang)壁(bi)、磚(zhuan)塊、石料沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)孔(kong)；電錘(chui)則主要(yao)用(yong)(yong)(yong)于較硬的混凝(ning)(ning)土、石料、墻(qiang)磚(zhuan)打(da)孔(kong)等(deng)場(chang)所。3、特點(dian)不(bu)同(tong)：沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)的用(yong)(yong)(yong)途廣泛、使用(yong)(yong)(yong)方(fang)便，但是沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)在使用(yong)(yong)(yong)時方(fang)向(xiang)不(bu)易(yi)把握(wo)，容易(yi)操作(zuo)(zuo)失誤，造成(cheng)開(kai)(kai)孔(kong)偏大(da)；加上(shang)鉆(zhan)(zhan)頭(tou)不(bu)鋒(feng)利，使所開(kai)(kai)的孔(kong)不(bu)工整，出現(xian)毛刺(ci)或裂紋；電錘(chui)的優點(dian)是效率高，孔(kong)徑(jing)大(da)、鉆(zhan)(zhan)進深度長，缺點(dian)就是震動(dong)大(da)，對(dui)周邊構(gou)筑物有(you)一定程(cheng)度的破壞作(zuo)(zuo)用(yong)(yong)(yong)。

四、多功能沖擊鉆怎么使用

1、在(zai)鉆(zhan)(zhan)(zhan)(zhan)(zhan)孔(kong)(kong)(kong)(kong)(kong)(kong)前(qian)，要先用(yong)(yong)鉛(qian)筆(bi)或粉筆(bi)在(zai)墻(qiang)上(shang)標出(chu)孔(kong)(kong)(kong)(kong)(kong)(kong)的(de)(de)位置，用(yong)(yong)中心沖(chong)(chong)(chong)(chong)子沖(chong)(chong)(chong)(chong)擊(ji)(ji)(ji)孔(kong)(kong)(kong)(kong)(kong)(kong)的(de)(de)圓心。2、選(xuan)擇(ze)筆(bi)直、鋒利、無損、與孔(kong)(kong)(kong)(kong)(kong)(kong)徑相同的(de)(de)沖(chong)(chong)(chong)(chong)擊(ji)(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)(tou)(tou)(tou)，打開沖(chong)(chong)(chong)(chong)擊(ji)(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)(zhan)的(de)(de)卡(ka)頭(tou)(tou)(tou)(tou)(tou)，將(jiang)(jiang)鉆(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)(tou)(tou)(tou)插到底(di)，用(yong)(yong)卡(ka)頭(tou)(tou)(tou)(tou)(tou)鑰匙將(jiang)(jiang)卡(ka)頭(tou)(tou)(tou)(tou)(tou)擰緊。3、選(xuan)擇(ze)適當(dang)的(de)(de)鉆(zhan)(zhan)(zhan)(zhan)(zhan)速(su)（孔(kong)(kong)(kong)(kong)(kong)(kong)徑大(da)時(shi)用(yong)(yong)低(di)速(su)，孔(kong)(kong)(kong)(kong)(kong)(kong)徑小時(shi)用(yong)(yong)高速(su)），鉆(zhan)(zhan)(zhan)(zhan)(zhan)堅硬的(de)(de)墻(qiang)和石頭(tou)(tou)(tou)(tou)(tou)時(shi)，要接(jie)通沖(chong)(chong)(chong)(chong)擊(ji)(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)(zhan)的(de)(de)沖(chong)(chong)(chong)(chong)擊(ji)(ji)(ji)附件(jian)。4、雙(shuang)手緊握沖(chong)(chong)(chong)(chong)擊(ji)(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)(zhan)，將(jiang)(jiang)鉆(zhan)(zhan)(zhan)(zhan)(zhan)尖抵在(zai)中心沖(chong)(chong)(chong)(chong)子沖(chong)(chong)(chong)(chong)擊(ji)(ji)(ji)的(de)(de)凹坑(keng)內，使(shi)鉆(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)(tou)(tou)(tou)與墻(qiang)面成(cheng)90°角，啟動沖(chong)(chong)(chong)(chong)擊(ji)(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)(zhan)，朝(chao)著鉆(zhan)(zhan)(zhan)(zhan)(zhan)孔(kong)(kong)(kong)(kong)(kong)(kong)方(fang)向均勻(yun)用(yong)(yong)力，并(bing)使(shi)鉆(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)(tou)(tou)(tou)始終保(bao)持(chi)著與墻(qiang)面的(de)(de)垂直。5、鉆(zhan)(zhan)(zhan)(zhan)(zhan)孔(kong)(kong)(kong)(kong)(kong)(kong)過程(cheng)中，不(bu)時(shi)移出(chu)鉆(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)(tou)(tou)(tou)以清除鉆(zhan)(zhan)(zhan)(zhan)(zhan)屑，直到鉆(zhan)(zhan)(zhan)(zhan)(zhan)孔(kong)(kong)(kong)(kong)(kong)(kong)作業完成(cheng)。
