摘要: 为了实现凸轮表面的激光淬火,根据凸轮淬火获取均匀硬化层的3个实现条件,结合激光加工机床的运动形式,采用建立激光淬火过程中激光束与凸轮表面之间相对运动数学模型的方法,对激光头的运动进行了理论分析及算法研究,从而得出X,ω,B 3轴运动的计算公式。结果表明,凸轮的激光淬火热处理运动是可控可行的,这为复杂工件的加工奠定了一定的理论基础。

Abstract: In order to realize the laser quenching heat treatment of cams,according to three preconditions for getting uniform hardened layer,combining with movement forms of laser processing machines,the mathematical models of relative movement were established about laser beam and the cam surface in the laser quenching process,the theoretic analysis and algorithm research were carried out for the laser head's movement,and the formulas of X,ω,B three-axis motion were derived. The result shows that the laser quenching heat treatment of the cam can be controlled feasibly,and it lays a theoretical foundation for the process of complex parts.
