激光熔覆是阀门密封面强化的理想技术手段,但三偏心蝶阀在结构上的特殊性使得其激光熔覆工艺路径规划需要三维空间位置的协调编程。采用平面夹具替代传统的斜锥面仿形夹具,基于六轴机器人与回转台的复合运动编程原理,提出了一种具有通用性、精确性的三偏心蝶阀蝶板密封面激光熔覆工艺路径规划方案,详细分析了转台和机器人夹持激光熔覆头的位置-时间曲线和位置调整速度-时间曲线。
Laser cladding is an ideal technique to strengthen the valve sealing surface. However, the structural specificity of the three-eccentric butterfly valve makes it necessary for the laser cladding process planning to coordinate programming in three-dimensional space. Based on the principle of compound motion programming of six-axis robot and swivel table, a planar fixture is used to replace the traditional conical taper fixture. A general and accurate three-eccentric butterfly valve sealing surface laser cladding process path planning Program, a detailed analysis of the turntable and the robot holding the laser cladding head position - time curve and position adjustment speed - time curve.
