The invention discloses a heavy-load high-precision lifting mechanism which comprises a bottom plate, a lifting mechanism and a lifting mechanism. Supporting blocks are arranged at the four corners of the bottom plate. Connecting plates matched with the supporting blocks are fixed to the four corners of the lower end of the lifting base, and the connecting plates and the supporting blocks are connected in a vertically sliding mode through first air floatation guide rail pairs in the vertical direction; a lifting driving module, the second air floating guide rail is horizontally mounted on the bottom plate; the second air floating slide block is sleeved on the second air floating guide rail; the third air floating guide rail is arranged at the upper end of the second air floating slide block in a penetrating manner and is obliquely distributed; the driving seat is arranged between the second air floating sliding blocks and is fixedly connected with the second air floating sliding blocks; the flat plate type linear motor is mounted on the bottom plate and is used for driving the driving seat to do linear motion; and the lower end of the connecting seat is provided with an inclined plane, the inclined plane is fixedly connected with the upper end face of the third air floating guide rail, and the horizontal plane of the upper end of the connecting seat is fixedly connected with the lifting seat, so that the lifting seat is installed on the lifting driving module.

    本发明公开一种重负载高精度升降机构,其包括:底板,该底板四个角部均设有支撑块;升降座,该升降座下端四个角部均固定有与支撑块适配的连接板,该连接板与支撑块通过竖直方向的第一气浮导轨副形成可上下滑动的连接;升降驱动模组,其包括水平安装于底板上的第二气浮导轨、套设于第二气浮导轨上的第二气浮滑块、穿设于该第二气浮滑块上端并倾斜分布的第三气浮导轨、设置于第二气浮滑块之间并与第二气浮滑块固定连接的驱动座以及安装于该底板上并用于驱动该驱动座直线运动的平板型直线电机;连接座,该连接座下端具有倾斜面,该倾斜面与第三气浮导轨上端面固定连接,且该连接座上端的水平面与升降座固定连接,使升降座安装于该升降驱动模组上。
