缸体机械加工工艺设计

中文译文
缸体机械加工工艺设计(中文3400字,英文2000字)
发动机缸体是发动机零件中结构较为复杂的箱体零件，其精度要求高，加工工艺复杂，并且加工加工质量的好坏直接影响发动机整个机构的性能，因此，它成为各个发动机生产厂家所关注的重点零件之一。
1. 发动机缸体的工艺特点
缸体为一整体铸造结构，其上部有4个缸套安装孔；缸体的水平隔板将缸体分成上下两部分；缸体的前端面从到后排列有三个同轴线的凸轮轴安装孔和惰轮轴孔。

英文原文
Cylinder block machining process design
Engine parts engine block is a more complex structure of spare parts box, its high precision, complex process, and the processing quality will affect the overall performance engine, so it has become the engine manufacturer's focus parts one.
1.Technical Characteristics of the engine cylinder block
Cylinder cast for a whole structure, and its upper part 4 cylinder mounting hole;cylinder standard cylinder is divided into upper and lower divisions into two parts;cylinder to the rear of the front-side arrangement of the previous three coaxial mounting hole of the camshaft and the idler axle hole.
Cylinder process features are: the structure of complex shape; processing plane,more than holes; uneven wall thickness and stiffness is low; processing of high precision typical of box-type processing part. The main processing of the surface of cylinder block top surface, the main bearing side, cylinder bore, the main and camshaft bearing bore holes and so on, they will directly affect the machining accuracy of the engine assembly precision and performance, mainly rely on precision equipment, industrial fixtures reliability and processing technology to ensure the reasonableness.
