摘　　要：为解决含轮廓误差的鞋底自动打磨问题,提出了弹性打磨方法。首先,将鞋底轮廓分为理论轮廓和制造误差两部分,由鞋底两自由度运动跟踪鞋底的理论轮廓,由弹性磨头的接触变形适应鞋底的制造误差,建立描述鞋底轮廓的数学模型;其次,将磨头力控与鞋底运动控制相结合,建立弹性打磨机构的动力学模型,仿真不同磨头偏角条件下鞋底与磨头之间的接触力,研究弹性打磨的关键参数;最后,开发了鞋底弹性打磨试验系统,验证了弹性打磨的可行性和有效性。To address the problem of automatically roughening the sole with some contour error,an elastic roughing method is proposed.Firstly,the sole contour is divided into theoretical contour and manufacturing error.The mathematical model describing the sole contour is established.The theoretical contour of the sole is tracked by the two degree of freedom motion of the sole.The manufacturing error of the sole contour is adapted by the deformation of the grinding head under the contact action.Secondly,combining the force control of the grinding head with the motion control of the sole,the dynamic model of the elastic roughing mechanism is established.The contact force changes between the sole and the grinding head under different grinding head postures are simulated,and the key parameters of the elastic roughing are studied.Finally,the test system of sole elastic grinding mechanism is developed,and the feasibility and effectiveness of the elastic roughing of the sole are verified by experiments.
