Abstract:
The components of miniaturized quick response valve have the characteristics of small feature size and high requirement for geometric tolerance, and the machining and assembling deviation of parts will result in valve failure.In order to solve the above problem, the deviation transfer equation was built and analyzed based on the mathematical model of three-dimensional dimension chain.It can locate the part processing and assembly that has a great influence on the valve performance as well as controlling the process.By applying the above analysis method, the assembling dimension chain of a miniaturized quick response valve was established and the closed loop deviation transfer equation was solved, which can conclude that the machining and assembling process of valve spool and valve seat have a great influence on the operational performance.Therefore, the corresponding process method is developed for machining and assembling process of the part.
