缸体机械加工工艺设计

缸体机械加工工艺设计(中文4400字,英文2800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，且加工质量的好坏直接影响发动机整机性能，因此，它成为各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
发动机缸体是发动机的基础零件和骨架，同时又是发动机总装配时的基准零件。缸体的作用是支承和保证活塞、连杆、曲轴等运动部件工作时的准确位置；保证发动机的换气、冷却和润滑；提供各种辅助系统、部件及发动机的安装。

Cylinder block machining process design
    Engine parts in the engine block is a more complex structure of spare parts box, its high precision, processing, 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
Engine block is the basic engine parts and skeleton, while the engine when the general assembly of the base components. Cylinder's role is supporting and ensuring the piston, connecting rod, crankshaft and other moving parts work, the exact location; to ensure the engine ventilation, cooling and lubrication; to provide a variety of auxiliary systems, components and engine installation.
