第川页CA6140 feed box designAuthor:Tutor:AbstractThe CA6140 horizontal lathe is a general-purpose universal machine with aprecision level,which can complete many processing techniques in production.It can turn awide range of threads,including metric,inch,modular,and pitch threads.Therefore,thetransmission mechanism of the feed transmission chain must be changed strictly according tothe standard pitch sequence.CA6140 type horizontal lathe feed box is fixed on the left frontof the bed.It has a feed motion changing device and operating mechanism.Its function is tochange the pitch of the processed thread or the feed of the motorized feed.The conversiondevice includes a shift mechanism for realizing the inverse relationship and special factors;abasic pitch mechanism for turning the threads whose lead values are arranged in equal series;a multiplication mechanism for achieving a multiple of the lead value of the turning threadRelationship change thread.Keywords:feed box,operating mechanism,change mechanism,basic pitch mechanism,doubling mechanism
