摘　　要：针对传统切割器传动装置采用齿轮机构和平面曲柄摇杆机构相结合方式的缺点,提出了采用实用空间连杆机构,对机构进行了三维建模和运动分析,得到了输出的位移、速度、加速度运动方程,并通过仿真得到了运动曲线。仿真结果显示,该机构可以实现割刀的平稳输出,为以后的机构尺寸综合打下了基础。A new spatial linkage mechanism was designed for three dimensional modeling construction and motion mechanism analysis in terms of current defects in traditional cutter transmission device which adopted gear mechanism combining with planar crank-rocker mechanism. The output displacement, speed and acceleration equation of motion were obtained, and the motion diagrams of cutter using spatial linkages mechanism were simulated. The simulation results showed that the mechanism could achieve the smooth output of the cutter, it would establish the basis for the next dimensional synthesis.
