This design start with the production conditions ofthe 5 thspindle bearings covered ofthe 492Q crankshaft fixture todetermine the most appropriate structure. The objective ofthis paper are: plete aboring fixture design and adrilling ficture design ofthefifth 492Q crank spindle bearing covered. Incourse ofthe design process, firstly the processes tobeanalyzed,the structure ofparts tobe identified, the goal ofthis design tobecleared; Secondly, I analyze the various types ofthe fixture todetermine the optimal scheme afixture byanalysing various fixture types parative analysis and error calculation, accuracy calculation, clamping force calculation, clamping point analysis .The paper also increased aboutthe knowledge ofboring and drill ing ,the knife mold.
