The T-joint process of the casting has quality requirements for the roughness of the flange end surface and inner hole surface of each joint,as well as the positional accuracy of the connecting hole.Therefore,considering the actual situation of the enterprise,a three-axis CNC milling machine is used to cut and drill the workpiece.Due to the irregular shape of T-sjoints,ordinary fixtures cannot effectively constrain their degrees of freedom.To ensure machining accuracy,it is necessary to modify the fixtures for T-joint joints.The improved fixture can effectively clamp the workpiece,meet the processing requirements of surface quality and positional accuracy,and can be used for mass production,improving production efficiency.
