- 摘要:
- 小型化快响应阀门的组成零件特征尺寸小、形位公差要求高,其加工和装配过程中易偏差积累过大,导致阀门性能不合格。针对此类问题,以空间装配尺寸链数学模型为基础,通过构建、分析偏差传递方程,定位零件加工和装配中对阀门性能影响大的环节,并对该环节进行工艺控制。通过建立某小型化快响应电磁阀的装配尺寸链,计算封闭环偏差传递方程,得出阀杆和阀座的加工和装配过程是影响阀门使用性能的重要环节。根据分析结果,制定出了满足要求的零件加工和装配工艺方案。
- 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.
