The invention relates to a high-precision jacking mechanism which sequentially comprises a bottom plate, a jacking assembly and a carrying plate from bottom to top. The jacking assembly comprises a guide base, a direct drive motor and a lead screw transmission assembly, the driving end of the top of the direct drive motor drives the carrier plate above through the lead screw transmission assembly to move in the vertical direction, and base plates are installed on the left side and the right side of the bottom of the carrier plate correspondingly. The substrate is connected with the guide base on the inner side through the guide rail assembly distributed in the vertical direction, and at least one sensor assembly and one grating assembly are further installed between the substrate and the guide base. The direct drive motor is mainly used for being matched with lead screw transmission, a high-precision grating ruler system and the like, the jacking mechanism has the advantages of being high in precision and stability, and the overall precision of laser machining can be improved.

    本发明涉及一种高精度顶升机构,从下往上依次包括底板、顶升组件和载板;顶升组件包括导向基座、直驱电机和丝杆传动组件,直驱电机顶部的驱动端通过丝杆传动组件驱动上方的载板在竖直方向上移动,在载板底部的左右两侧均安装有基板;基板通过沿着竖直方向分布的导轨组件与内侧的导向基座相连接,且在基板与导向基座之间还安装有至少一个传感器组件和光栅组件。本发明主要是使用直驱电机配合丝杆传动以及高精度光栅尺系统等,顶升机构具有高精度、高稳定性的好处,可提升激光加工的整体精度。
