為減小立式機座變形(xing),在機(ji)座的出產過程中有(you) 注重(zhong)一下幾點(dian):
1、鑄件(jian)應在清砂和噴涂防銹漆(qi)后(hou)進行(xing)時(shi)效處置,以內應力;
2、精(jing)車時(shi)不宜選(xuan)用徑向夾緊,避免導致裝(zhuang)夾變(bian)形;
3、轉移(yi)時要(yao)當(dang)心輕放,不要(yao)粗(cu)野操作,避免導致意外變(bian)形;
4、機(ji)(ji)座(zuo)(zuo)的止口和(he)內圓(yuan)加(jia)(jia)工(gong)(gong),有(you) 分出車和(he)精(jing)車兩道工(gong)(gong)序(xu)進行。這樣,可減小切削(xue)熱效果所(suo)導致(zhi)的變(bian)形,有(you)時(shi)(shi)也便于(yu)組織(zhi)在(zai)粗精(jing)不一樣的機(ji)(ji)床上進行加(jia)(jia)工(gong)(gong)。在(zai)主(zhu)動線上加(jia)(jia)工(gong)(gong)機(ji)(ji)座(zuo)(zuo)時(shi)(shi),通(tong)常在(zai)出車和(he)精(jing)車工(gong)(gong)序(xu)之間,設置冷(leng)(leng)卻工(gong)(gong)序(xu)或(huo)組織(zhi)其他工(gong)(gong)序(xu),使工(gong)(gong)件(jian) 充沛冷(leng)(leng)卻;
立(li)式機座的檢(jian)修(xiu)方法(fa)及(ji)標準:
1.機(ji)座與針齒殼接觸面應當(dang)平(ping)整光滑,裝配嚴密。
2.殼體不應有裂紋和砂眼。
