The invention relates to a connecting rod lifting device which comprises a first rotary shaft and a second rotary shaft arranged in parallel, wherein a first driven arm is mounted on the first rotaryshaft; a second driven arm is mounted on the second rotary shaft; a servo motor is in drive joint with a speed reducer; a driving arm is mounted on the output shaft of the servo motor; one end of a first connecting rod is hinged to the driving arm; the other end of the first connecting rod is hinged to one end of the first driven arm; one end of a second connecting rod is hinged to the other end of the first driven arm; the other end of the second connecting rod is hinged to the second driven arm; swing arms are mounted at two ends of the first rotary shaft and the second rotary shaft; a cam follower is mounted at the external end of each of the swing arms; a lifting platform is placed on the cam follower; a guide sleeve is mounted on the lifting platform and is matched with a vertically arranged guide column; the driving arm rotates, the first connecting rod drives the first driven arm and the first rotary shaft to rotate; the first driven arm drives the second driven arm and the second rotary shaft to rotate through the second connecting rod; the swing arms drive the cam follower to lift the lifting platform to ascend and descend; and rotary motion is converted into lifting motion of the lifting platform.
本发明涉及连杆升降装置,包含平行布置的转轴一和转轴二,转轴一上安装有从动臂一,转轴二上安装有从动臂二,伺服电机与减速机传动连接,其输出轴上安装主动臂,连杆一的一端与主动臂相铰接,连杆一的另一端与从动臂一的一端相铰接,连杆二的一端与从动臂一的另一端相铰接,连杆二的另一端与从从动臂二相铰接;转轴一和转轴二的两端分别安装一摆臂,每一摆臂的外端安装有凸轮随动器,升降平台置于凸轮随动器上;升降平台上安装有导向套,导向套与竖立设置的导向柱配合。主动臂转动,连杆一驱动从动臂一及转轴一转动,从动臂一通过连杆二驱动从动臂二及转轴二转动,摆臂摆动带动凸轮随动器托起升降平台升降。旋转运动转化为升降平台升降运动。
