强力气缸夹紧机构
本专利技术涉及一种汽车焊装设备,特别涉及一种强力气缸夹紧机构。
技术介绍
强力气缸亦称欧标气缸,目前已被广泛应用,但欧标气缸安装使用方式单一,夹紧块的夹紧路径单一,以强力气缸转动轴为中心的圆形轨迹,在设计时旋转点的位置确定比较困难;如在一些特殊场合,夹紧块需要按照一定的抛物线轨迹运行,以避让工件,但强力气缸旋转点和运动轨迹无法满足这一要求,故此往往需要更改设计方案,采用强力气缸和直线运动机构配合使用,或重新制定整套夹具或抓具的设计方案,更换夹具或抓具的定位点位置,以适应强力气缸的运动轨迹,这样往往会增大设计难度使得操作工艺更加复杂。因此,在采用强力气缸的夹紧机构设计中,提供一种设计合理,结构简单,性能稳定可靠,运动轨迹为近似直线加曲线的组合线段的夹紧机构,是该领域技术人员亟待着手解决的问题之一。
