一种板材冲压用辅助定位装置

Abstract

本实用新型公开了一种板材冲压用辅助定位装置，涉及板材冲压领域，包括工作台，箱体，所述箱体安装于工作台上，还包括一对L形压板；一对L形压板呈对角设置，一对L形压板活动安装于所述箱体内，一对L形压板均开设有L形腔，所述L形腔内固定安装有一对固定块，所述L形腔内转动安装有一对螺纹杆，所述螺纹杆与固定块转动连接，一对所述螺纹杆上均铰接有第一螺纹块，所述第一螺纹块上固定连接有伸缩板，所述伸缩板与L形压板滑动连接，有效解决了现有的板材冲压用定位装置大多采用对板材两侧进行固定的方式，但是对薄板材进行冲压时，采用这种固定方式会使另两侧的约束不足，容易发生翘曲、变形，影响冲压效果的技术问题。
