摘　　要：基于SolidWorks Motion反向合成设计凸轮轮廓,利用双凸轮-连杆机构,实现步进装置的近似椭圆整周运动。进行运动学仿真和分析,得到了凸轮曲线的动态性能指标,验证了凸轮性能满足设计要求。通过对转向装置关键部件的设计,在无需外部动力驱动的条件下,利用自身相对运动实现了杆件同步的2次90°旋转和1次45°旋转。结果表明,随动多角度转向步进输送装置很好地达到了预期目标,提高了抽油杆锻造生产机械化水平,并可推广用于其它圆柱形杆件多工位、多角度转向的自动化加工。The cam contour curves are designed by the reverse synthetic method based on SolidWorks Motion, and the whole periodic approximate elliptical motion of the stepping transmission device is realized by the double cam-linkage mechanism. According to the kinematics simulation and analysis, the dynamic performance indexes are obtained, which show that the cam contour curves meet the design requirement. Through the design of the critical components of the steering device, the rods can rotate 90°twice and 45°once synchronously by their relative motion without any external force. The results show that the device achieves the expected goals, improves the mechanization level of the sucker rod forging, and can be expended for other cylindrical rods＇ multi-position and multi-angle steering automatic processing.
