Design and Experimental Research of Special Turning Tool for Machining Seat Holes of Parallel Gate Valve
Parallel gate valves are widely used in oil drilling equipment.The ordinary inner hole turning tool is used to process the seat hole of parallel gate valve,and it is difficult to use the cutting fluid,and because the rigidity and hardness of the tool rod is small,which causes"shaking"phenomenon,it is difficult to ensure the machining quality and shape and position tolerance of the seat hole when machining the workpiece.Based on this,a set of special turning tools is designed to increase the rigidity and hardness of the tool rod,making it convenient to use the cutting fluid,and only one clamping is needed to avoid the u-turn ma-chining,so as to meet the geometric tolerance and machining quality requirements of the seat hole.Finite element method is used to check the strength of the designed tool.The experimental results show that the designed tool can improve the machining effi-ciency and meet the requirements of machining quality and geometric tolerance accuracy.
