门把手10万次寿命测试设备的研制

Development of Equipment for Testing Door Handles Thousands of Times

研制了一种基于继电器与接近开关控制的门把手10万次寿命测试设备。对设备的工作原理、整体设计思路、机械部件结构(基础部件、执行机构、夹具组件)、控制与计数部件等进行了详细介绍.最后给出整体设计简图,并对利用设备样机测试前后门把手的易损零部件金相组织图进行对比。

This paper develops the equipment for testing door handles thousands of times. The equipment are controlled by the relay and the proximity switch. It also introduces its working principle, overall design concept, the mechanical component structure （ inclu- ding basic components, actuator and fixture components）, and controlling and counting components in detail. Finally, it describes the overall design diagrams and contrasts the microstructure maps of the vulnerable parts of the door handle which are not tested with those which are tested by the equipment prototype.
