PROBLEM TO BE SOLVED: To provide a workpiece lifting device which facilitates downsizing and stabilization of the device, also facilitates adjustment of actuation means of a lifting platform, and can follow a fitting part of a loaded workpiece.SOLUTION: A workpiece lifting device 10 comprises: a base 1; a lifting platform 2 disposed above the base for loading a workpiece thereon; a pair of arm members 3 which are connected rotatably to the base and the lifting platform, and in which intermediate parts 33 are bent; a pair of link pieces 4 which are connected rotatably to vertical positions of the intermediate parts 33 in the arm members, and in which intermediate parts 43 are bent in a direction opposite from the arm members; and an actuation member 5 for moving the lifting platform vertically. The intermediate parts 43 of the link pieces 4 are provided with a connection arm 6 for connecting the intermediate parts with each other. The actuation member 5 comprises a drive part 52 mounted to the base 1, and an action part 51 which is mounted to the lifting platform 2 and is extended and contracted by the drive part. The action part is mounted at an intermediate position 22 of upper connection parts 23 where the lifting platform and the pair of arm members are connected.SELECTED DRAWING: Figure 2

    【課題】装置の小型化及び安定化が容易であって、昇降台の作動手段の調整が簡単、かつ、搭載したワークの取付部への追従が可能なワーク昇降装置を提供する。【解決手段】基台1と、当該基台の上方に配置されワークを搭載する昇降台2と、基台と昇降台とに回動自在に連結され中間部33が屈曲する一対のアーム部材3と、アーム部材における中間部33の上下位置に回動自在に連結されアーム部材とは逆方向に中間部43が屈曲する一対のリンク片4と、昇降台を上下動させる作動部材5とを備えるワーク昇降装置10である。リンク片4の中間部43には、互いを連結する連結アーム6を備え、作動部材5には、基台1に装着された駆動部52と、昇降台2に装着され駆動部によって伸縮する作用部51とを備え、作用部は、昇降台と一対のアーム部材とが連結された上連結部23同士の中間位置22に装着された。【選択図】図2
