The invention relates to a built-in rotary lifting device. The built-in rotary lifting device comprises a fixing base, a motor, a slewing bearing, a rotary lifting support, a rotary lifting workbench and a guide seat, and the inner ring of the slewing bearing is fixed on the fixing base; the motor is fixed on the inner ring of the slewing bearing and drives the outer ring of the slewing bearing to rotate through a matched gear on the motor; the rotary lifting support is fixed on the outer ring of the slewing bearing, rotates along with the outer ring of the slewing bearing, and transmits power to the rotary lifting workbench through a thread; the outer contour of the guide seat is matched with the inner wall of a rotary workbench in a vertical groove shape, the rotary lifting workbench is prevented from moving up and down in the vertical groove direction along with rotation of the rotary lifting support, and therefore the rotary lifting workbench ascends and descends. The built-in rotary lifting device has the advantages of simple structure, good stability, large lifting amplitude, simple appearance and good controllability.
本发明涉及一种内置式旋升装置,它包括固定底座、电机、回转支承、旋升支架、旋升工作台及导向座,回转支承的内圈固定在固定底座上;电机固定在回转支承的内圈上,并通过电机上的配套的齿轮带动回转支承的外圈旋转;旋升支架固定在回转支承的外圈上,随回转支承的外圈旋转,通过螺纹传递动力给旋升工作台;导向座外廓与旋转工作台内壁为竖槽状配合,阻止旋升工作台随旋升支架旋转而沿着竖槽方向上下位移,从而实现旋升工作台的上升和下降。优点结构简单、稳定性好、升降幅度大,外观简洁、操控性好。
