摘要
突跳式温控器为实现自动上料完成自动化装配,计划采用振动盘振动的上料方式.为了研究振动对突跳式温控器性能的影响规律,验证突跳式温控器受振动影响的可靠性,对突跳式温控器进行了振动相关的实验研究和分析.通过实验研究得到不同复位方式和不同材质突跳式温控器受振动后的影响规律,在实验研究的基础上,针对不同动作温度的突跳式温控器,通过MiniTAB软件对测试数据进行方差、时间序列等统计分析,得到直观动作温度变化趋势.通过对突跳式温控器的物理剖解和结构分析,得到陶瓷杆与双金属片的位移、温控器材质对温控器产生温度漂移的影响较大,为后续突跳式温控器使用振动上料提供理论指导和参考.
Abstract
In order to realize the automatic assembly of automatic feeding,the snap-action thermostats are planned to adopt the feeding method of vibrating plate vibration.In order to study the influence of vibration on the performance of the snap-action thermostats and verify the reliability of the snap-action thermostats affected by vibration,the vibration-related experimental research and analysis of the snap-action thermostats were carried out.Through experimental research,the influence of different reset methods and different materials on the vibration of the snap-action thermostats were obtained.On the basis of experimental research,the test data were statistically analyzed by MiniTAB software for the snap-action thermostats with different operating temperatures,such as variance and time series,and the intuitive operating temperature change trend was obtained.Through the physical analysis and structural analysis of the snap-action thermostats,it is obtained that the displacement of the ceramic rod and the bimetal sheet and the material of the thermostats have a great influence on the temperature drift of the thermostats,which provides theoretical guidance and reference for the subsequent use of vibration feeding of the snap-action thermostats.
