翻边装置在尾门总成夹具中的应用与研究

Application and research on flanging device in the tailgate assembly fixture

首先介绍了翻边装置在某汽车尾门总成夹具上的应用,通过在尾门总成夹具上增设带切换翻边装置,满足了尾门总成数模中无法通过包边模一次性包边区域的压合要求,通过夹具上的夹紧定位销对尾门总成进行孔定位,再通过夹钳部位的型面夹紧装置对型面进行夹紧及定位,确保翻边精度与外观质量要求。重点讲述了带切换翻边装置的夹具结构及工作原理,通过气缸、导杆、旋转轴、翻边刀块等的结构设计,实现了该特殊包边需求。实际生产证明,该翻边装置能有效地应用在尾门总成夹具上,满足了生产中对压合区域的翻边精度与外观质量要求,降低了车型工装的开发成本,并且实现了翻边压合,提高了生产效率。

The of application flanging device in automobile tailgate assembly fixture was introduced,and pressing requirement in edging area,which could not be once finished by edging die in tailgate assembly model,was met by adding flanging device with a switch to tailgate assembly fixture. Then,the hole of the panel was positioned by positioning pin in fixture,and the profiles were clamped and positioned by clamping device located in the surface of clamping position to ensure the accuracy and appearance quality requirements. Furthermore,the structure and working principle of fixture with flanging device were mainly described,and the special hemming needs were realized by the structure design of cylinder,guide rod,rotation axis and flanging knife block. Practical production proves that the flanging device can be effectively used in tailgate assembly fixture,and the flanging accuracy and appearance quality requirements in pressing area are met. Thus,the development cost is reduced,the flanging pressing requirement is realized,and the production efficiency is improved.
