The invention discloses a platform lifting mechanism, which comprises a base, a platform installed on the base and two driving assemblies, wherein the two driving assemblies are installed at the two opposite ends of the base respectively, each driving assembly comprises a driving piece, a cam and a sliding block; the driving pieces are fixed to the base, and the cams are fixedly installed on output shafts of the driving pieces; the sliding blocks are installed on the base in a sliding mode and provided with inclined faces; the inclined faces abut against the platform; the driving pieces drivethe cams to rotate; the cams eccentrically move to abut against the sliding blocks to transversely move relative to the base; and the inclined faces of the sliding blocks abut against the platform toenable the platform to move in the vertical direction relative to the base. Through the above design, the platform lifting mechanism is small in size, simple in structure and low in cost on the premise of keeping high moving precision.

    本发明公开了一种平台升降机构,包括底座、安装于底座的平台以及两驱动组件,两驱动组件分别安装于底座的相对两端,每一驱动组件包括驱动件、凸轮以及滑动块,驱动件固定于底座,凸轮固定安装于驱动件的输出轴,滑动块滑动安装于底座,滑动块设有斜面,斜面与平台抵触,驱动件带动凸轮转动,凸轮偏心运动抵触滑动块相对底座横向移动,滑动块的斜面抵触平台使平台相对底座在竖直方向上移动,通过上述设计,平台升降机构在保持移动精度高的前提下,尺寸小、结构简单、成本低。
