一种新型内置夹具的设计

A new built-in fixture design

设计了一种新型内置夹具,该夹具以CATIA为设计平台,可以实现不同车型的白车身总成焊接。新型内置夹具主要包括主框架、单气缸定位平移-夹紧机构、连杆翻转+单气缸双夹紧机构、双导柱气缸夹紧机构、滑移机构及其他部件。该新型内置夹具可以从空中进入白车身内部对白车身进行定位夹紧,使外部空间全部让出,便于机器人自动焊接,提高了生产效率,提升了我国自主发展焊装核心技术的能力。

A new type built-in fixture was proposed,the built-in fixture which based on CATIA platform can realize different model of body in white welding assembly.The new built-in fixture including a main frame,positioning and translation-clamping mechanism with single cylinder,the link flipped ＋ single cylinder double clamping mechanism,clamping mechanism with double guide cylinder,sliding mechanism and other components.The new built-in fixture can enter the body in white from the air,then perform positioning and clamping,makes room for automatic welding robots,the production efficiency is increased,the ability of independent development welding core technology in our country is improved.
