汽车安全气囊螺纹拧紧机构的分析

Analysis of Tightening Mechanism of Screw Thread in Automobile Airbag

安全气囊是一种在汽车事故碰撞中自动充气膨胀,在二次冲撞中保护乘员、减轻伤害的安全保护装置。在发生碰撞事故时,安全气囊能否正常地工作,直接影响着乘员保护情况的关键。因此这就要求其在装配过程中螺纹连接组以等高度、等扭矩、高技术来进行。人工手动装配其工作过程单一、枯燥、劳动强度大且容易出错,精度也不高,难以满足安全性保护装置的装配要求。为改善这些问题设计了高效率、智能化的安全气囊螺母拧紧设备的拧紧机构。自动拧紧设备能够高效、高精度、自动化完成螺母的拧紧。

The safety airbag is a safety protection device which is used for automatically inflating and inflating in the collision of an automobile accident and protecting passengers and reducing damage in the two collision. In the event of collision,whether the airbag can work properly, directly affects the protection situation of the crew. Therefore, it requires that the screw connection group with the characters of same height, torque, high technology in the process of its assembly. Manual assembly process is simple, boring, high labor intensity and error prone, and its accuracy is not high, it is difficult to meet the requirements of safety protection device assembly. In order to solve these problems, the high efficiency and intelligent tightening mechanism of the airbag nut＇ s tightening device is designed. The automatic tightening device can be used for high efficiency, high precision and automation.
