6、的方式，生產(chǎn)效率比通用機(jī)床高幾倍至幾十倍。由于通用部件已經(jīng)標(biāo)準(zhǔn)化和系列化，可根據(jù)需要靈活配置，能縮短設(shè)計(jì)和制造周期。多軸箱是組合機(jī)床的核心部件。它是選用通用零件，按專用要求進(jìn)行設(shè)計(jì)的，在組合機(jī)床設(shè)計(jì)的過程中，是工作量較大的部件之一。它是根據(jù)工序圖和加工示意圖所確定的工件加工孔的數(shù)量和位置，切削用量和主軸類型設(shè)計(jì)的傳遞各主軸運(yùn)動(dòng)的動(dòng)力部件。其動(dòng)力來自通用的動(dòng)力箱，與動(dòng)力箱一起安裝于進(jìn)給滑臺，可完成鉆，絞等加工工序。本課題設(shè)計(jì)了用于HT20
