半軸零件的機(jī)械加工工藝及夾具設(shè)計(jì)


摘要
半軸是汽車的軸類中承受扭矩最大的零件，它是差速器和驅(qū)動(dòng)輪之間傳遞扭矩的實(shí)心軸，其內(nèi)端一般通過花鍵與半軸齒輪連接，外端與輪轂連接，該零件在機(jī)械設(shè)備中具有傳動(dòng)性，在進(jìn)行半軸的工藝和工裝設(shè)計(jì)時(shí)，首先對半軸的工藝性進(jìn)行了詳細(xì)的分析，設(shè)計(jì)出了加工的工藝過程，根據(jù)加工要求設(shè)計(jì)專用夾具設(shè)計(jì)，一付是用來車削半軸的外圓，一付是用來鉆削半軸圓盤上均勻分布的小孔，在設(shè)計(jì)中注意的夾具的經(jīng)濟(jì)性和使用性，盡量降低加工時(shí)的成本，減少工人的勞動(dòng)強(qiáng)度，除此還進(jìn)行了組合量具的設(shè)計(jì)，用來檢查6個(gè)均勻分布的小孔的位置度公差。

Abstract
    The half stalk is in automotive stalk the acceptance twist the biggest spare parts of sqire , it is bad soon machine and drive the round of delivers to twist the  of solid stalk, it inside carry generally pass to spend the key and half stalk wheel gears to connect, carry outside with a conjunction, that spare parts is in the machine equipments have to spread to move sex, at carry on the half stalk of craft and work equip to account, the half axial craft carried on the detailed analysis first, designing processed craft process, according to process to request to design the appropriation tongs design, a pay is to use to come to car to pare the outside circle of the half stalk, on pay is use to drill to pare a dish of the half stalk up even distribute of eyelet, in the design the economy of the advertent tongs and usage, as far as possible lower to process of cost, reduce the worker of labor strength, in addition to this still carried on the design that the combination quantity have, use to check 6 even distribute of a business trip of position of the eyelet.
Key Words：The craft work packs the design   The tongs design    Combine the quantity has the design
