Abstract：The casting pouring arm of the traditional continuous pouring machine adopted the method of vertical downward scooping molten aluminum,which was unable to effectively detect the height of molten aluminum,resulting in uneven scooping of aluminum liquid,or even scooping of molten aluminum,or scooping to the surface oxide layer of aluminum liquid,which would lead to a serious decline in the quality of aluminum casting and low working efficiency.On the basis of theoretical calculation,a casting arm structure based on end operation of industrial robot was designed.The results show that the industrial robot arm drives the casting ladle,which can realize the setting of multi-angle and large range of arbitrary actions with high flexibility and strong adaptability.The closure of the chain is connected with the basket screw,the tension is convenient and reliable,and it can meet the requirements of turning accuracy.
