摘　　要：针对刚性汽车玻璃夹具生产效率低、制造成本高和开发周期长等缺点,为了提高汽车的制造自动化和柔性化水平,利用真空负压吸附技术,研发出一种用于安装汽车玻璃定位销的新型夹具,并设计了一款用于薄壁曲面件定位夹紧的柔性支撑吸盘机构。由于该柔性夹具的定位块和夹紧块的位置可以根据每款汽车玻璃的具体形状尺寸进行重新调整,所以基于有限元理论,结合VB和ANSYS软件研发出柔性汽车玻璃夹具布局优化系统来提高夹具的定位精度。Aiming at the disadvantages of low production efficiency,high manufacturing cost and long development cycle for the rigid car glass,in order to improve the level of manufacturing automation and flexibility,using vacuum adsorption technology,this paper develops a new type of fixture for the installation of automotive glass dowel pins and designs a flexible supporting suction sucker mechanism for positioning and clamping thin-walled curved surface.The position of the positioning block and the block of flexible fixture can be readjusted according to the specific shape and size of each kind of automotive glass,therefore,based on Finite Element Theory,this paper developed a flexible automobile glass fixture layout optimization system to improve the positioning accuracy of the fixture with VB and ANSYS.
