中文摘要SUV 后桥减速器位于传动系的末端，为了保证 SUV 汽车的优越性能，后桥减速器必须能承受在恶劣环境下高强度的工作。其中，减速器外壳有着保护内部零件的作用，同时还要与桥壳进行定位联接，因此对它的设计制造提出了很高的要求。本次设计包括以下内容： 减速器壳体上孔的镗加工工序分析，镗加工定位基准、定位元件的选择，夹具的夹紧装置设计和夹紧力及切削力的计算，减速器壳体和镗夹具的三文造型设计，以及夹具和减速器壳体的工程图生成。6468

Title The Three Dimensional Modeling Design of the SUV
Rear Axle Reducing Gear Shell Boring Jig Abstract
The topic of this paper is the design of the boring jig used to processing
the rear axle reducer shell of SUV automobiles. The reducer is located
at the terminal of the power transmission of the car. To ensure quality
performance of the car, the rear axle reducer must be able to work in high
intensity under adverse circumstances. Among all the components of a rear
axle reducer, the reducer shell is particularly challenging to design and
manufacture due to its crucial functions of protecting the internal
components of the reducer and forming connections with the axle housing.
This project entails analyzing the reducer shell hole boring process,
locating the boring process using the primary datum, choosing setting
elements, designing the jig clamp, calculating the clamping force of the
jig clamp, calculating the cutting force of the boring process, 3D modeling
of the reducer shell and boring jig, and producing the engineering drawings
of the reducer shell and the clamping jig.
