一、沖擊鉆更換鉆頭的方法

沖(chong)(chong)(chong)擊(ji)(ji)(ji)鉆(zhan)(zhan)(zhan)，又稱(cheng)沖(chong)(chong)(chong)擊(ji)(ji)(ji)電(dian)(dian)鉆(zhan)(zhan)(zhan)，是一(yi)(yi)種用于磚、砌塊及輕質墻(qiang)等材料(liao)上(shang)(shang)鉆(zhan)(zhan)(zhan)孔(kong)的(de)電(dian)(dian)動工具，以(yi)旋轉(zhuan)切(qie)削為(wei)主(zhu)，兼有依靠(kao)操作(zuo)者推力生(sheng)產沖(chong)(chong)(chong)擊(ji)(ji)(ji)力的(de)沖(chong)(chong)(chong)擊(ji)(ji)(ji)機構，以(yi)垂直往復(fu)運動依靠(kao)沖(chong)(chong)(chong)擊(ji)(ji)(ji)力進行鉆(zhan)(zhan)(zhan)孔(kong)。使用沖(chong)(chong)(chong)擊(ji)(ji)(ji)鉆(zhan)(zhan)(zhan)時，需要(yao)需要(yao)根(gen)據不同(tong)的(de)作(zuo)業情況更換鉆(zhan)(zhan)(zhan)頭(tou)(tou)，更換方法是：1、切(qie)斷電(dian)(dian)源(yuan)，把(ba)沖(chong)(chong)(chong)擊(ji)(ji)(ji)鉆(zhan)(zhan)(zhan)倒放在地上(shang)(shang)，鉆(zhan)(zhan)(zhan)頭(tou)(tou)朝(chao)上(shang)(shang)。2、旋開帶齒的(de)轉(zhuan)環，拿出沖(chong)(chong)(chong)擊(ji)(ji)(ji)鉆(zhan)(zhan)(zhan)上(shang)(shang)的(de)鉆(zhan)(zhan)(zhan)頭(tou)(tou)，一(yi)(yi)般鉆(zhan)(zhan)(zhan)頭(tou)(tou)部(bu)位(wei)有可上(shang)(shang)下活動的(de)塑膠(jiao)圈，左手(shou)向(xiang)下按(an)住(zhu)鉆(zhan)(zhan)(zhan)頭(tou)(tou)根(gen)部(bu)的(de)塑膠(jiao)圈，右手(shou)握住(zhu)鉆(zhan)(zhan)(zhan)頭(tou)(tou)向(xiang)上(shang)(shang)提即可取出。3、取出原來(lai)的(de)鉆(zhan)(zhan)(zhan)頭(tou)(tou)后，把(ba)新的(de)鉆(zhan)(zhan)(zhan)頭(tou)(tou)插入沖(chong)(chong)(chong)擊(ji)(ji)(ji)鉆(zhan)(zhan)(zhan)的(de)正中(zhong)間(jian)，再反著轉(zhuan)動剛(gang)松開的(de)轉(zhuan)環，讓它咬(yao)合(he)住(zhu)剛(gang)放進去的(de)鉆(zhan)(zhan)(zhan)頭(tou)(tou)，卡緊(jin)即可。4、檢查(cha)一(yi)(yi)下看看有沒有鎖牢固鉆(zhan)(zhan)(zhan)頭(tou)(tou)，插上(shang)(shang)電(dian)(dian)源(yuan)，把(ba)沖(chong)(chong)(chong)擊(ji)(ji)(ji)鉆(zhan)(zhan)(zhan)朝(chao)下，開起電(dian)(dian)源(yuan)試用一(yi)(yi)下，沒有問(wen)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(zuo)原(yuan)理不(bu)(bu)同(tong)(tong)：沖(chong)擊(ji)鉆(zhan)主(zhu)要(yao)(yao)(yao)依靠(kao)旋轉和(he)(he)沖(chong)擊(ji)來(lai)(lai)工(gong)(gong)作(zuo)，單一的(de)(de)沖(chong)擊(ji)非常輕微，但可以(yi)產生連續的(de)(de)力(li)；電(dian)錘(chui)(chui)則(ze)要(yao)(yao)(yao)依靠(kao)旋轉和(he)(he)捶(chui)打(da)(da)來(lai)(lai)工(gong)(gong)作(zuo)，單個捶(chui)打(da)(da)力(li)非常高，并有較高的(de)(de)捶(chui)打(da)(da)頻率。2、適用(yong)(yong)(yong)對(dui)象不(bu)(bu)同(tong)(tong)：沖(chong)擊(ji)鉆(zhan)主(zhu)要(yao)(yao)(yao)適用(yong)(yong)(yong)于在木材、金屬、陶(tao)瓷(ci)和(he)(he)塑料上進行鉆(zhan)孔，也(ye)可以(yi)對(dui)混(hun)凝土(tu)地板、墻壁、磚塊、石料沖(chong)擊(ji)鉆(zhan)孔；電(dian)錘(chui)(chui)則(ze)主(zhu)要(yao)(yao)(yao)用(yong)(yong)(yong)于較硬的(de)(de)混(hun)凝土(tu)、石料、墻磚打(da)(da)孔等場所。3、特點不(bu)(bu)同(tong)(tong)：沖(chong)擊(ji)鉆(zhan)的(de)(de)用(yong)(yong)(yong)途(tu)廣泛、使用(yong)(yong)(yong)方(fang)便(bian)，但是(shi)沖(chong)擊(ji)鉆(zhan)在使用(yong)(yong)(yong)時方(fang)向不(bu)(bu)易(yi)把握，容(rong)易(yi)操(cao)作(zuo)失(shi)誤，造成(cheng)開(kai)孔偏大(da)；加(jia)上鉆(zhan)頭(tou)不(bu)(bu)鋒利，使所開(kai)的(de)(de)孔不(bu)(bu)工(gong)(gong)整，出現毛刺或裂紋(wen)；電(dian)錘(chui)(chui)的(de)(de)優點是(shi)效率高，孔徑大(da)、鉆(zhan)進深度長，缺點就(jiu)是(shi)震動大(da)，對(dui)周邊(bian)構筑物(wu)有一定程度的(de)(de)破壞作(zuo)用(yong)(yong)(yong)。

四、多功能沖擊鉆怎么使用

1、在鉆(zhan)(zhan)孔(kong)(kong)前，要(yao)先(xian)用鉛筆(bi)或粉筆(bi)在墻上標(biao)出(chu)孔(kong)(kong)的位(wei)置，用中(zhong)心沖(chong)(chong)子沖(chong)(chong)擊(ji)孔(kong)(kong)的圓心。2、選擇筆(bi)直(zhi)、鋒利(li)、無損(sun)、與孔(kong)(kong)徑(jing)相同的沖(chong)(chong)擊(ji)鉆(zhan)(zhan)頭(tou)(tou)，打開沖(chong)(chong)擊(ji)鉆(zhan)(zhan)的卡頭(tou)(tou)，將(jiang)鉆(zhan)(zhan)頭(tou)(tou)插到底，用卡頭(tou)(tou)鑰(yao)匙將(jiang)卡頭(tou)(tou)擰(ning)緊。3、選擇適(shi)當的鉆(zhan)(zhan)速(su)（孔(kong)(kong)徑(jing)大時用低(di)速(su)，孔(kong)(kong)徑(jing)小時用高速(su)），鉆(zhan)(zhan)堅硬的墻和石頭(tou)(tou)時，要(yao)接(jie)通沖(chong)(chong)擊(ji)鉆(zhan)(zhan)的沖(chong)(chong)擊(ji)附(fu)件。4、雙手緊握沖(chong)(chong)擊(ji)鉆(zhan)(zhan)，將(jiang)鉆(zhan)(zhan)尖抵在中(zhong)心沖(chong)(chong)子沖(chong)(chong)擊(ji)的凹(ao)坑內，使鉆(zhan)(zhan)頭(tou)(tou)與墻面(mian)(mian)成90°角，啟(qi)動沖(chong)(chong)擊(ji)鉆(zhan)(zhan)，朝著(zhu)鉆(zhan)(zhan)孔(kong)(kong)方向均勻用力(li)，并使鉆(zhan)(zhan)頭(tou)(tou)始終保持著(zhu)與墻面(mian)(mian)的垂直(zhi)。5、鉆(zhan)(zhan)孔(kong)(kong)過程中(zhong)，不時移出(chu)鉆(zhan)(zhan)頭(tou)(tou)以(yi)清除鉆(zhan)(zhan)屑，直(zhi)到鉆(zhan)(zhan)孔(kong)(kong)作業完成。
