機床夾具在我們機械加工中的重要作用表現。
傳統的機械加工方法主(zhu)要(yao)有(you):車、銑、刨、磨、鉆、鏜等。
機械加工(gong)(gong),分:冷加工(gong)(gong),熱加工(gong)(gong),化學(xue)加工(gong)(gong),特種加工(gong)(gong)。方法(fa)繁多,過程嚴(yan)謹,技術含量(liang)高,涉及學(xue)科(ke)廣,從(cong)業(ye)人員多,社會(hui)貢獻大。
說起機(ji)(ji)械加(jia)工我(wo)們(men)(men)它(ta)其中(zhong)重(zhong)要(yao)的一項工具(ju)我(wo)們(men)(men)不(bu)得不(bu)了解到(dao),它(ta)就(jiu)是我(wo)們(men)(men)的機(ji)(ji)床夾具(ju),它(ta)對我(wo)們(men)(men)的機(ji)(ji)械加(jia)工有(you)著怎樣的作用(yong)。
關于它的(de)作用我們分幾個方面詳細的(de)介紹一下。
1、保證加工精(jing)度
采用夾具(ju)安裝,可以準確(que)地確(que)定工件與機床(chuang)、刀(dao)具(ju)之(zhi)間的(de)相(xiang)互位置,工件的(de)位置精度由夾具(ju)保(bao)證,不(bu)受工人(ren)技術水平的(de)影響,其(qi)加工精度高而且穩定。
2、提高生產率、降低(di)成本
用(yong)(yong)夾(jia)(jia)(jia)具(ju)裝夾(jia)(jia)(jia)工(gong)(gong)(gong)件(jian)(jian),無(wu)需找正便能使(shi)工(gong)(gong)(gong)件(jian)(jian)迅速地(di)定(ding)位(wei)和夾(jia)(jia)(jia)緊(jin),分明地(di)添加了(le)(le)輔佐工(gong)(gong)(gong)時;用(yong)(yong)夾(jia)(jia)(jia)具(ju)裝夾(jia)(jia)(jia)工(gong)(gong)(gong)件(jian)(jian)提高(gao)了(le)(le)工(gong)(gong)(gong)件(jian)(jian)的(de)剛性(xing),因此(ci)可加大切削用(yong)(yong)量(liang)(liang);可以運用(yong)(yong)多件(jian)(jian)、多工(gong)(gong)(gong)位(wei)夾(jia)(jia)(jia)具(ju)裝夾(jia)(jia)(jia)工(gong)(gong)(gong)件(jian)(jian),并(bing)采用(yong)(yong)高(gao)效(xiao)夾(jia)(jia)(jia)緊(jin)機構(gou),這(zhe)些要素均有利于提高(gao)休息消費率。另外,采用(yong)(yong)夾(jia)(jia)(jia)具(ju)后,產質(zhi)量(liang)(liang)量(liang)(liang)動搖(yao),廢品率下降(jiang),可以布置技術等級(ji)較低(di)的(de)工(gong)(gong)(gong)人,清楚地(di)降(jiang)低(di)了(le)(le)消費本錢。
3、擴大(da)機(ji)床的工(gong)藝范圍
運(yun)用(yong)(yong)公用(yong)(yong)夾具可以(yi)改(gai)動原機(ji)床(chuang)(chuang)的(de)用(yong)(yong)處和擴展機(ji)床(chuang)(chuang)的(de)運(yun)用(yong)(yong)范圍,完成一(yi)機(ji)多能(neng)。例如,在車床(chuang)(chuang)或搖臂鉆(zhan)床(chuang)(chuang)上裝置(zhi)鏜模夾具后,就(jiu)可以(yi)對(dui)箱(xiang)體孔系停(ting)止鏜削(xue)加工;經過公用(yong)(yong)夾具還可將車床(chuang)(chuang)改(gai)爲拉床(chuang)(chuang)運(yun)用(yong)(yong),以(yi)充沛發揚通用(yong)(yong)機(ji)床(chuang)(chuang)的(de)作用(yong)(yong)。
4、減輕工人的勞動(dong)強(qiang)度
用(yong)夾具裝夾工(gong)件方便、快速,當采用(yong)氣動、液(ye)壓等夾緊裝置時(shi),可減輕工(gong)人(ren)的勞(lao)動強度
