活塞杆开胶故障分析及改进措施

Cause Analysis of Rubber Cracking Problem of Piston Rod and Corrective Actions

针对飞机座舱盖开启机构活塞杆开胶问题,分别从裂纹断口微观形貌、能谱、胶料和胶粘剂质量、金属骨架表面处理工艺、胶粘剂涂覆和硫化工艺等方面进行原因分析。通过等离子体表面处理技术和超声波脱脂技术处理金属骨架表面,采用智能视觉自动涂覆胶粘剂技术,加强过程控制等改进措施,可有效解决活塞杆开胶问题。

In order to solve the rubber cracking problem of piston rod,the causes were analyzed from the aspects of crack morphology,energy spectrum,quality of rubber material and adhesive,surface treatment of metal framework,adhesive application and curing process.The rubber cracking problem was then effectively solved by taking the corrective actions such as plasma surface treatment,ultrasonic degreasing process and intelligent visual automatic gluing technology.
