一、沖擊鉆更換鉆頭的方法

沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)(zhan)，又稱(cheng)沖(chong)(chong)(chong)擊(ji)電鉆(zhan)(zhan)(zhan)，是一種用于磚、砌塊(kuai)及輕質墻(qiang)等材料上鉆(zhan)(zhan)(zhan)孔(kong)的(de)(de)(de)(de)電動(dong)工具(ju)，以旋轉切(qie)削為(wei)主(zhu)，兼有依靠(kao)操作(zuo)(zuo)者推(tui)力(li)生產沖(chong)(chong)(chong)擊(ji)力(li)的(de)(de)(de)(de)沖(chong)(chong)(chong)擊(ji)機構，以垂直(zhi)往(wang)復(fu)運動(dong)依靠(kao)沖(chong)(chong)(chong)擊(ji)力(li)進行(xing)鉆(zhan)(zhan)(zhan)孔(kong)。使用沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)(zhan)時，需(xu)要需(xu)要根據不(bu)同的(de)(de)(de)(de)作(zuo)(zuo)業情況更換鉆(zhan)(zhan)(zhan)頭(tou)(tou)，更換方法是：1、切(qie)斷電源，把(ba)沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)(zhan)倒放(fang)在地(di)上，鉆(zhan)(zhan)(zhan)頭(tou)(tou)朝上。2、旋開(kai)帶齒的(de)(de)(de)(de)轉環，拿出(chu)(chu)沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)(zhan)上的(de)(de)(de)(de)鉆(zhan)(zhan)(zhan)頭(tou)(tou)，一般鉆(zhan)(zhan)(zhan)頭(tou)(tou)部位有可上下活動(dong)的(de)(de)(de)(de)塑膠(jiao)圈，左手(shou)向下按住鉆(zhan)(zhan)(zhan)頭(tou)(tou)根部的(de)(de)(de)(de)塑膠(jiao)圈，右手(shou)握(wo)住鉆(zhan)(zhan)(zhan)頭(tou)(tou)向上提即(ji)可取出(chu)(chu)。3、取出(chu)(chu)原來的(de)(de)(de)(de)鉆(zhan)(zhan)(zhan)頭(tou)(tou)后，把(ba)新(xin)的(de)(de)(de)(de)鉆(zhan)(zhan)(zhan)頭(tou)(tou)插入沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)(zhan)的(de)(de)(de)(de)正中(zhong)間，再反著轉動(dong)剛松(song)開(kai)的(de)(de)(de)(de)轉環，讓它咬合住剛放(fang)進去(qu)的(de)(de)(de)(de)鉆(zhan)(zhan)(zhan)頭(tou)(tou)，卡緊即(ji)可。4、檢(jian)查一下看(kan)看(kan)有沒(mei)有鎖牢固鉆(zhan)(zhan)(zhan)頭(tou)(tou)，插上電源，把(ba)沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)(zhan)朝下，開(kai)起(qi)電源試(shi)用一下，沒(mei)有問題(ti)即(ji)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)作(zuo)原理不同(tong)：沖(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)主(zhu)要(yao)(yao)依(yi)靠旋(xuan)轉(zhuan)和沖(chong)(chong)擊(ji)(ji)來工(gong)作(zuo)，單一的(de)(de)沖(chong)(chong)擊(ji)(ji)非常輕微，但(dan)可以(yi)產生連(lian)續的(de)(de)力(li)；電錘則(ze)要(yao)(yao)依(yi)靠旋(xuan)轉(zhuan)和捶打(da)(da)來工(gong)作(zuo)，單個捶打(da)(da)力(li)非常高(gao)，并(bing)有較高(gao)的(de)(de)捶打(da)(da)頻率(lv)。2、適用(yong)(yong)對(dui)象不同(tong)：沖(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)主(zhu)要(yao)(yao)適用(yong)(yong)于(yu)在木材、金屬、陶瓷和塑料(liao)(liao)上進(jin)行鉆(zhan)(zhan)孔(kong)，也可以(yi)對(dui)混凝土地板、墻壁、磚(zhuan)塊(kuai)、石料(liao)(liao)沖(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)孔(kong)；電錘則(ze)主(zhu)要(yao)(yao)用(yong)(yong)于(yu)較硬的(de)(de)混凝土、石料(liao)(liao)、墻磚(zhuan)打(da)(da)孔(kong)等場所。3、特(te)點不同(tong)：沖(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)的(de)(de)用(yong)(yong)途廣泛、使(shi)用(yong)(yong)方(fang)便，但(dan)是沖(chong)(chong)擊(ji)(ji)鉆(zhan)(zhan)在使(shi)用(yong)(yong)時(shi)方(fang)向(xiang)不易(yi)把握(wo)，容易(yi)操作(zuo)失(shi)誤，造成開孔(kong)偏大(da)；加上鉆(zhan)(zhan)頭(tou)不鋒利(li)，使(shi)所開的(de)(de)孔(kong)不工(gong)整，出現毛刺或裂紋；電錘的(de)(de)優(you)點是效率(lv)高(gao)，孔(kong)徑大(da)、鉆(zhan)(zhan)進(jin)深(shen)度長，缺點就是震動大(da)，對(dui)周邊構筑物有一定程度的(de)(de)破(po)壞作(zuo)用(yong)(yong)。

四、多功能沖擊鉆怎么使用

1、在鉆(zhan)(zhan)(zhan)(zhan)孔(kong)(kong)前，要先用(yong)(yong)鉛筆(bi)或粉(fen)筆(bi)在墻上標出(chu)孔(kong)(kong)的(de)位置，用(yong)(yong)中(zhong)心(xin)(xin)沖(chong)(chong)(chong)子沖(chong)(chong)(chong)擊(ji)孔(kong)(kong)的(de)圓心(xin)(xin)。2、選擇筆(bi)直(zhi)、鋒利(li)、無損、與(yu)孔(kong)(kong)徑(jing)(jing)相同的(de)沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)，打開沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)(zhan)(zhan)的(de)卡頭(tou)(tou)，將鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)插到底，用(yong)(yong)卡頭(tou)(tou)鑰匙將卡頭(tou)(tou)擰緊。3、選擇適當的(de)鉆(zhan)(zhan)(zhan)(zhan)速(su)（孔(kong)(kong)徑(jing)(jing)大時用(yong)(yong)低速(su)，孔(kong)(kong)徑(jing)(jing)小時用(yong)(yong)高速(su)），鉆(zhan)(zhan)(zhan)(zhan)堅硬的(de)墻和石頭(tou)(tou)時，要接通沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)(zhan)(zhan)的(de)沖(chong)(chong)(chong)擊(ji)附件。4、雙手緊握沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)(zhan)(zhan)，將鉆(zhan)(zhan)(zhan)(zhan)尖抵在中(zhong)心(xin)(xin)沖(chong)(chong)(chong)子沖(chong)(chong)(chong)擊(ji)的(de)凹坑內(nei)，使鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)與(yu)墻面成90°角(jiao)，啟動沖(chong)(chong)(chong)擊(ji)鉆(zhan)(zhan)(zhan)(zhan)，朝著(zhu)鉆(zhan)(zhan)(zhan)(zhan)孔(kong)(kong)方向均勻(yun)用(yong)(yong)力，并使鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)始終保(bao)持著(zhu)與(yu)墻面的(de)垂直(zhi)。5、鉆(zhan)(zhan)(zhan)(zhan)孔(kong)(kong)過程中(zhong)，不時移出(chu)鉆(zhan)(zhan)(zhan)(zhan)頭(tou)(tou)以清除鉆(zhan)(zhan)(zhan)(zhan)屑，直(zhi)到鉆(zhan)(zhan)(zhan)(zhan)孔(kong)(kong)作業完成。
