Research on constant torque control method for electric impact wrench
摘要
Abstract
The constant torque control of electric impact wrench was studied.Firstly,the collision model and torque accumulation model of electric impact wrench were established,and the factors affecting the torque output of wrench were analyzed.A constant torque control scheme based on impact times and impact block speed was proposed.At the same time,the collection scheme of impact times and the speed control scheme of double closed-loop DC brushless motor based on fuzzy PID were designed.Verified on the torque test platform of electric impact wrench,the results show that the torque control accuracy of the wrench can reach within±4％when the impact times are 200 times.The constant torque control method has the characteristics of high control ac-curacy,low cost and convenient operation.The feasibility of this method was verified by practical application.关键词
