北京机械加工厂通过自身经(jing)验总(zong)结,铣床在用(yong)到(dao)一定的时间时,需要及时保(bao)养(yang),需要注意的有下面几点:
1.每3个月(yue)清洁床(chuang)身内部、升降台(tai)(tai)内部和(he)作业台(tai)(tai)底座的光(guang)滑油池、用汽油清洁光(guang)滑油泵的游油网,每年不少于(yu)两次。
2.机床各部空(kong)(kong)(kong)(kong)(kong)隙(xi)的(de)调(diao)(diao)整(zheng):主轴(zhou)光滑的(de)调(diao)(diao)整(zheng),必(bi)须(xu)保证每(mei)分钟有(you)(you)一滴油经过(guo);作(zuo)业台纵(zong)向(xiang)丝(si)(si)杠(gang)传动(dong)空(kong)(kong)(kong)(kong)(kong)隙(xi)的(de)调(diao)(diao)整(zheng),每(mei)3个月调(diao)(diao)整(zheng)或依(yi)据实践(jian)使用情况(kuang)进行(xing)调(diao)(diao)整(zheng),要求是(shi)传动(dong)空(kong)(kong)(kong)(kong)(kong)隙(xi)充分减小,丝(si)(si)杠(gang)的(de)空(kong)(kong)(kong)(kong)(kong)隙(xi)不超过(guo)1/40转,一起在(zai)全(quan)长上都不得(de)有(you)(you)卡(ka)住(zhu)表象;作(zuo)业合(he)纵(zong)向(xiang)丝(si)(si)杠(gang)轴(zhou)向(xiang)空(kong)(kong)(kong)(kong)(kong)隙(xi)的(de)调(diao)(diao)整(zheng),意图(tu)是(shi)消除丝(si)(si)杠(gang)和螺母之(zhi)间的(de)传动(dong)空(kong)(kong)(kong)(kong)(kong)隙(xi),一起还要使丝(si)(si)杠(gang)在(zai)轴(zhou)线方向(xiang)与作(zuo)业台之(zhi)间的(de)合(he)作(zuo)空(kong)(kong)(kong)(kong)(kong)隙(xi)到达最小;主轴(zhou)轴(zhou)承径向(xiang)空(kong)(kong)(kong)(kong)(kong)隙(xi)的(de)调(diao)(diao)整(zheng),依(yi)据实践(jian)使用情况(kuang)进行(xing)调(diao)(diao)整(zheng)。
3.升降丝杠用二(er)硫化铝油剂每(mei)两月光(guang)滑一次。
4.作(zuo)业台疾速移动离(li)合器的调整要(yao)求;冲(chong)(chong)突(tu)离(li)合器脱开(kai)时(shi),冲(chong)(chong)突(tu)片之间(jian)的总(zong)和空隙不(bu)应该少于2~3mm;冲(chong)(chong)突(tu)离(li)合器闭合时(shi),冲(chong)(chong)突(tu)片应严(yan)密地压(ya)紧(jin),而且电(dian)磁(ci)铁的铁芯(xin)要(yao)彻底(di)拉紧(jin),假如(ru)电(dian)磁(ci)铁的铁芯(xin)合作(zuo)得准确(que),在拉紧(jin)状况中电(dian)磁(ci)铁不(bu)会有响声。
