The invention discloses an automatic lifting device. The device comprises a rack, a material frame for carrying material trays and a progressive mechanism, wherein the material frame is arranged on the rack in a sliding manner and is linked with the progressive mechanism; the progressive mechanism comprises a first rack, a first pushing block which is engageable with the first rack and a locking assembly for locking the material frame on the rack, the first rack is vertically mounted on the material frame, and a plurality of teeth are uniformly arranged on the first rack at equal intervals; the first pushing block is engaged with the first rack and synchronously drives the material frame to ascend and descend relative to the rack per a preset height, wherein the preset height is an integermultiple of spacing between every two adjacent teeth in the first rack; and the first pushing block is disengaged from the first rack, and the locking assembly locks the material frame on the rack. The device has the advantages that the structure is simple, material taking is convenient, and the production efficiency is improved.
本发明公开了一种自动升降装置,包括机架、承载料盘的料架和递进机构,料架呈滑动的安装于机架上并与递进机构联动;递进机构包括第一齿条、与第一齿条可啮合的第一推块及用于锁定料架于机架上的锁定组件,第一齿条呈竖直的安装于料架,第一齿条上呈均匀且等间距的设置有若干齿牙;第一推块与第一齿条啮合并同步带动料架相对机架按预设高度升降,预设高度为第一齿条中相邻两齿之间间距的整数倍;第一推块脱离与第一齿条啮合,锁定组件锁定料架于机架上。本发明结构简单,方便了取料,提高了生产效率。
