操作机的升降及倾斜机构是一个复杂的空间多杆机构,是操作机完成平行升降、俯仰、侧移、偏摆运动的主运动机构,也是吸收快锻压机锻造冲击的缓冲机构,其结构设计的好坏直接影响到操作机使用性能。本文通过解析法分析得到其几何方程组及受力情况方程组,快速、高效的对平行升降及倾斜机构进行设计,避免了大量的重复性工,并得到了载荷变化相对稳定的结构。结合ANSYS软件进行了进一步综合的研究多杆机构,使其满足了强度、疲劳、冲击等综合性要求。
The lifting and tilting mechanism of the manipulator is a complicated space multi-bar mechanism. It is the main movement mechanism for the manipulator to complete parallel movements of lift, pitch, side shift and yaw. It is also the buffering mechanism that absorbs the forging impact of the fast forging press. Its structure design The quality of a direct impact on operating machine performance. In this paper, the geometrical equations and stress equations are obtained by analytic method, and the parallel lifting and tilting mechanism is designed quickly and efficiently, avoiding a lot of repetitive work, and the structure with relatively stable load change is obtained. Combined with ANSYS software, a multi-lever mechanism was further comprehensively studied to meet the comprehensive requirements of strength, fatigue and impact.
