摘 要
本文設(shè)計(jì)了二級(jí)減速器上箱體機(jī)械加工工藝規(guī)程，合理選擇了工藝過程中的機(jī)床刀具和量具，設(shè)計(jì)了銑分割面工序和鉆螺栓孔工序的專用機(jī)床夾具。并計(jì)算了該夾具使用的精度保證，計(jì)算結(jié)果表明兩套夾具均可，保證了零件的加工要求。
關(guān)鍵詞 機(jī)械加工工藝規(guī)程；機(jī)床夾具；定位；定位誤差
Abstract
This text designs the last body machine of second class deceleration machine to process the craft rules distance, the reasonable chooses the tool machine knife within the craft process to have and measure, designing the 銑 to partition to face the work preface and drill the appropriation tool machine tongs of the stud bolt bore work preface.Also computed that tongs the accuracy of the usage assurance, the calculation as a result expresses that two sets of tongs all can, guarantee the spare parts to process the request.
The keyword machine processes the craft rules distance;Tool machine tongs;Fixed position;Position the error margin
