The invention provides an automatic lifting device and a sliding table lifting system. The automatic lifting device comprises a power mechanism, a transmission mechanism connected with the power mechanism and a pair of lifting assemblies connected to the two sides of the transmission mechanism, wherein each lifting assembly comprises a plurality of lifting guide blocks and a supporting beam located above the lifting guide blocks; inclined guide grooves and guide wheels which are matched with each other are arranged between the supporting beam and the lifting guide blocks, and the guide wheels are clamped in the inclined guide grooves; and the height of the supporting beam can be changed through relative movement of the guide wheels and the inclined guide grooves. Compared with the prior art, the automatic lifting device has the advantages that the lifting guide blocks of the lifting assemblies are driven through the transmission mechanism, the lifting guide blocks drive the supporting beams to ascend and descend, and then lifting motion of a sliding table is achieved, so that rolling wheels of the sliding table can abut against and support a bearing object upwards or break away from the bearing object downwards according to needs, and the service life of the rolling wheels is prevented from being influenced due to long-time supporting of the bearing object.

    本申请提供了一种自动升降装置及滑台升降系统,自动升降装置包括动力机构、与动力机构相连的传动机构以及连接于传动机构两侧的一对升降组件,所述升降组件包括若干升降导引块及位于升降导引块上方的支撑梁,所述支撑梁与所述升降导引块之间设有相互配合的斜向导引槽与导引轮,所述导引轮卡持于所述斜向导引槽内并可通过两者的相对运动来改变所述支撑梁的高度。与现有技术相比,本申请通过传动机构驱动升降组件的升降导引块,由升降导引块驱动支撑梁的上升与下降,进而实现了滑台的升降运动,使得滑台的滚轮可根据需要向上抵接支撑承载物或向下脱离承载物,避免了滚轮因长时间支撑承载物而影响使用寿命。
