一、沖擊鉆更換鉆頭的方法

沖(chong)(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)，又稱沖(chong)(chong)(chong)擊(ji)(ji)電(dian)鉆(zhan)(zhan)(zhan)(zhan)，是一種用于(yu)磚、砌(qi)塊(kuai)及輕(qing)質墻等(deng)材(cai)料上(shang)鉆(zhan)(zhan)(zhan)(zhan)孔的(de)(de)(de)電(dian)動(dong)工具，以旋轉切(qie)削(xue)為主(zhu)，兼有(you)(you)依靠(kao)操作者推力生(sheng)產沖(chong)(chong)(chong)擊(ji)(ji)力的(de)(de)(de)沖(chong)(chong)(chong)擊(ji)(ji)機(ji)構，以垂直(zhi)往復運動(dong)依靠(kao)沖(chong)(chong)(chong)擊(ji)(ji)力進行鉆(zhan)(zhan)(zhan)(zhan)孔。使用沖(chong)(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)時，需要需要根(gen)(gen)據不同的(de)(de)(de)作業(ye)情況(kuang)更換鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)(tou)(tou)，更換方法是：1、切(qie)斷電(dian)源(yuan)，把(ba)沖(chong)(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)倒(dao)放(fang)在(zai)地(di)上(shang)，鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)(tou)(tou)朝上(shang)。2、旋開帶齒的(de)(de)(de)轉環，拿出沖(chong)(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)上(shang)的(de)(de)(de)鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)(tou)(tou)，一般鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)(tou)(tou)部(bu)位有(you)(you)可上(shang)下(xia)(xia)活(huo)動(dong)的(de)(de)(de)塑膠圈，左手向下(xia)(xia)按住鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)(tou)(tou)根(gen)(gen)部(bu)的(de)(de)(de)塑膠圈，右手握住鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)(tou)(tou)向上(shang)提(ti)即可取出。3、取出原來的(de)(de)(de)鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)(tou)(tou)后，把(ba)新的(de)(de)(de)鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)(tou)(tou)插(cha)入(ru)沖(chong)(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)的(de)(de)(de)正中(zhong)間，再反著轉動(dong)剛松開的(de)(de)(de)轉環，讓它咬合(he)住剛放(fang)進去的(de)(de)(de)鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)(tou)(tou)，卡緊(jin)即可。4、檢查一下(xia)(xia)看看有(you)(you)沒(mei)(mei)有(you)(you)鎖牢固鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)(tou)(tou)，插(cha)上(shang)電(dian)源(yuan)，把(ba)沖(chong)(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)(zhan)(zhan)朝下(xia)(xia)，開起電(dian)源(yuan)試用一下(xia)(xia)，沒(mei)(mei)有(you)(you)問題(ti)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、工作原理不同(tong)：沖(chong)(chong)擊(ji)(ji)鉆(zhan)主(zhu)要(yao)依靠旋轉和沖(chong)(chong)擊(ji)(ji)來工作，單一(yi)的(de)沖(chong)(chong)擊(ji)(ji)非(fei)(fei)常(chang)輕微，但(dan)可以產生連續的(de)力(li)(li)；電(dian)(dian)錘(chui)則要(yao)依靠旋轉和捶(chui)(chui)打來工作，單個(ge)捶(chui)(chui)打力(li)(li)非(fei)(fei)常(chang)高(gao)，并(bing)有較(jiao)高(gao)的(de)捶(chui)(chui)打頻率。2、適用對(dui)象(xiang)不同(tong)：沖(chong)(chong)擊(ji)(ji)鉆(zhan)主(zhu)要(yao)適用于在木材(cai)、金屬、陶瓷和塑料上(shang)進行鉆(zhan)孔(kong)(kong)，也可以對(dui)混凝土(tu)地板、墻(qiang)壁、磚塊、石料沖(chong)(chong)擊(ji)(ji)鉆(zhan)孔(kong)(kong)；電(dian)(dian)錘(chui)則主(zhu)要(yao)用于較(jiao)硬的(de)混凝土(tu)、石料、墻(qiang)磚打孔(kong)(kong)等場(chang)所。3、特點(dian)不同(tong)：沖(chong)(chong)擊(ji)(ji)鉆(zhan)的(de)用途廣泛、使用方便，但(dan)是沖(chong)(chong)擊(ji)(ji)鉆(zhan)在使用時方向不易把握，容易操作失(shi)誤(wu)，造成開孔(kong)(kong)偏大；加上(shang)鉆(zhan)頭不鋒利，使所開的(de)孔(kong)(kong)不工整，出現毛刺或裂(lie)紋；電(dian)(dian)錘(chui)的(de)優(you)點(dian)是效率高(gao)，孔(kong)(kong)徑大、鉆(zhan)進深度長，缺點(dian)就是震(zhen)動(dong)大，對(dui)周邊構筑物有一(yi)定(ding)程度的(de)破壞作用。

四、多功能沖擊鉆怎么使用

1、在鉆(zhan)(zhan)(zhan)孔(kong)前，要先用(yong)鉛筆(bi)或粉筆(bi)在墻上標出孔(kong)的(de)位置，用(yong)中(zhong)心(xin)沖(chong)(chong)(chong)子沖(chong)(chong)(chong)擊孔(kong)的(de)圓心(xin)。2、選擇筆(bi)直(zhi)(zhi)、鋒利(li)、無損、與孔(kong)徑相(xiang)同(tong)的(de)沖(chong)(chong)(chong)擊鉆(zhan)(zhan)(zhan)頭(tou)，打開沖(chong)(chong)(chong)擊鉆(zhan)(zhan)(zhan)的(de)卡(ka)(ka)頭(tou)，將(jiang)鉆(zhan)(zhan)(zhan)頭(tou)插到底，用(yong)卡(ka)(ka)頭(tou)鑰匙將(jiang)卡(ka)(ka)頭(tou)擰緊(jin)(jin)。3、選擇適當(dang)的(de)鉆(zhan)(zhan)(zhan)速(su)(su)（孔(kong)徑大時(shi)(shi)用(yong)低(di)速(su)(su)，孔(kong)徑小時(shi)(shi)用(yong)高速(su)(su)），鉆(zhan)(zhan)(zhan)堅(jian)硬(ying)的(de)墻和(he)石頭(tou)時(shi)(shi)，要接通沖(chong)(chong)(chong)擊鉆(zhan)(zhan)(zhan)的(de)沖(chong)(chong)(chong)擊附件。4、雙手緊(jin)(jin)握沖(chong)(chong)(chong)擊鉆(zhan)(zhan)(zhan)，將(jiang)鉆(zhan)(zhan)(zhan)尖抵在中(zhong)心(xin)沖(chong)(chong)(chong)子沖(chong)(chong)(chong)擊的(de)凹(ao)坑內，使鉆(zhan)(zhan)(zhan)頭(tou)與墻面成90°角，啟動沖(chong)(chong)(chong)擊鉆(zhan)(zhan)(zhan)，朝著鉆(zhan)(zhan)(zhan)孔(kong)方(fang)向均勻用(yong)力，并(bing)使鉆(zhan)(zhan)(zhan)頭(tou)始終保持著與墻面的(de)垂(chui)直(zhi)(zhi)。5、鉆(zhan)(zhan)(zhan)孔(kong)過程(cheng)中(zhong)，不時(shi)(shi)移出鉆(zhan)(zhan)(zhan)頭(tou)以(yi)清(qing)除鉆(zhan)(zhan)(zhan)屑，直(zhi)(zhi)到鉆(zhan)(zhan)(zhan)孔(kong)作業(ye)完成。
