摘要

This paper presents the customized equipment suittable to ending hole and interior plane processing of four-way valves, the customized equipment intergrates processing functions including burnishing, broaching, automatic workpiece loding and unloading. The operating principle of four-way valves is firstly presented; Then, the broaching process and burnishing process are respectively analyzed, on this basis, the basic structure of the customized equipment that integrating burnishing and broaching process is designed. Its operating principle is then presented, take the foundation for example, designs method of the key components of the customized equipment is presented; In the end, the application of the equipment is prospected. Practical application shows that the customized equipment is reliable, has simple structure and high degree automatization. In addition, it ensures easy maintenances and cleanness, can effectively improve the productivity of four-way valve.%设计了一种新型的空调专用四通阀端孔及内平面加工的专用机床,该专用机床集成挤光与拉削的加工工艺,并实现自动上下料.首先,介绍了四通阀工作原理；然后,分析了四通阀挤光和拉削加工工艺特点,在此基础上,设计了该挤光拉削一体化加工专机的机械结构；接着分析了其工作原理,并以底座为例,介绍了关键零部件的设计方法；最后给出了应用研究.应用结果表明,该四通阀加工专机工作可靠,结构简单,自动化程度高,便于维修、调整,可有效提高劳动生产率.
