摘要
螺栓连接是目前汽车工业最常用的连接工艺,其连接失效是汽车上是常见的产品问题,尤其以螺栓松动问题最为常见。通过对自攻锁紧螺栓研究,发现其具有高连接可靠性、可重复使用、低系统成本的优点,通过螺栓装配工艺开发,区分与普通螺栓的扭矩-夹紧力关系差异,确定装配工艺参数,实现产品可靠连接。
Bolt connection is the most commonly used connection technology in automobile industry,its connection failure is a common problem in automobiles,in particular,bolt looseness is the most common problem.Through the research on self-tapping locking bolt,it is found that it has the advantages of high connection reliability,repeated use and low system cost.Through the bolt assembly process development,the difference of torque-clamping force relationship with ordinary bolts was distinguished,the assembly process parameters were determined and reliable bolt connection was realized.
