搅拌摩擦焊工业机器人结构性能分析及实现研究

Structural performance analysis and realization research of industrial robot for friction stir welding

国外工业机器人搅拌摩擦焊已经应用阶段,国内还处于研究阶段。将负重能力为210 kg的ER210-C40机器人改造为搅拌摩擦焊机器人,利用有限元方法对其进行结构性能分析,在实际载荷条件下,机器人结构强度不能满足条件要求,所以必须采用其他方法以实现工业机器人搅拌摩擦焊。但用两台工业机器人同时加载的方法来实现生产线上的搅拌摩擦焊存在诸多不能解决的问题,因此必须采用负载能力更强的重载机器人来实现。

The industrial robot for friction stir welding has been applied in foreign countries,and is still in the research stage in China.The ER210-C40 robot with a load bearing capacity of 210kg is transformed into a friction stir welding robot.The structural performance of the robot is analyzed by the finite element method.Under the actual load condition,the robot is analyzed by the finite element method.The structure strength of the robot can not meet the requirements of the condition,so the other methods must be adopted to realize the friction stir welding of the industrial robot.However,there are many problems that can not be solved by using the method of two industrial robots at the same time to realize the friction stir welding of the industrial robot on the production line,so it is necessary to use more capable heavy load robot to realize it.
