一种两侧同步扩力夹紧机构
本专利技术涉及汽车制造辅助工装领域,具体涉及一种两侧同步扩力夹紧机构。
技术介绍
车架是非承载式车身汽车的底盘,由两根纵梁,多根横梁、前悬后悬支架、还有其他的一些支承小件组成,大多车架采是采用弧焊工艺,车架本身有较大的强度和刚性,弧焊接带的来变形力道大,难以控制。纵梁与横梁的主体结构一般是由两个U型板材扣合后焊接形成的矩形,焊接夹具对其的主要控制为两个U型件扣合后两侧的焊接间隙。目前该类焊接夹具采用的机构多数为一种正置气缸驱动,而且防护不完善的两侧同步的扩力夹紧机构。该机构占用空间较大,尤其是占用高度空间;同时防护无法做的完善,至少弧焊的焊接飞溅焊渣易飞入机构内部,造成堵塞卡死,故障率高,保养成本高。
