发动机缸体清洁度提升方法

Analysis on the Method of Improving Cleanliness of Engine Cylinder Block

发动机缸体作为发动机主要零部件之一,其清洁度对发动机的装配、使用性能及可靠性都有较大的影响。本研究以一款直列四缸发动机铸铁材料缸体为研究对象,从缸体机加工毛刺产生机理、毛刺去除等方面出发,研究缸体清洁度的提升方法。通过参数优化、刀具选型、去毛刺工具、加工工艺顺序调整等方法,来解决缸体毛刺问题,从而提升缸体的清洁度。

As one of the main parts of the engine,the cleanliness of the engine cylinder has an important impact on the assembly,performance and reliability of the engineIn this study,an in-line four-cylinder engine cast iron cylinder as the research object,from the cylinder machining burr generation mechanism,burr removal method to explore the method of cylinder cleanliness improvement.Through parameter opti⁃mization,tool selection,deburring tools,processing process sequence and other methods,to solve the burr problem of cylinder block,improve the cleanliness of the cylinder block.
