发动机气缸头气门精加工专用机床设计
|
摘要
通过分析发动机气缸头气门精加工精度要求,确定了气门的精加工工艺方案。根据工艺方案,制定了专用机床的整体布局方案,并对机床关键部件——专用夹具、专用数控滑台及专用主轴箱等的结构进行了设计,说明了各自的工作原理。此专用机床已在重庆某企业投产使用。通过实际加工实验,气门各项精度均达到企业的技术要求,气缸头的生产节拍为0.63 min/件,实际生产能力达到30万件/年以上。
By analyzing finishing accuracy requirements of the engine cylinder head valve,finishing process scheme of the valve was determined. According to the process scheme,overall layout scheme of the special machine was formulated. Then the key components' structure of the special machine was designed,including special fixtures,special CNC slider and special headstock,etc. In addition,their respective working principle was expounded. The designed process and the special machine tool were successfully implemented in an enterprise in Chongqing. Through the actual machining experiments,the valve precision met enterprise requirements,and the takt is of 0. 63 min / pc. The actual production capacity reaches more than 300000 / year.
