摘　　要：为了提高模锻生产线上工件卡紧效果,设计了一种3活塞液压径向卡盘。从径向卡盘控制原理层面出发,根据变质量液压原理和运动学理论构建夹紧模型,利用径向卡盘测试台对模型进行了准确性验证,并根据卡紧性能验证结果完成了卡盘设计结构优化。仿真和实验结果表明:3.2 mm碟簧下卡紧与松开的响应时间依次为0.33 s与0.35 s。液压系统的泄漏导致仿真结果出现小幅偏差,但总体上获得了与仿真响应时间相近的测试结果。2.4 mm碟簧下卡紧与松开的响应时间依次为0.325 s与0.301 s。仿真时间0.321 s,测试时间为0.326 s;经过改进处理后,改进径向卡紧时间达到了与卡盘相近程度,能够达到现场使用要求。实际测试跟仿真曲线达到良好的吻合状态,获得了同样的反应时间。研究结果为优化卡盘结构设计提供有益指导。In order to improve the clamping of the workpiece in the die forging production line,a hydraulic radial chuck with three pistons is designed.Based on the control principle of the radial chuck,the clamping model is constructed according to the variable mass hydraulic principle and kinematic theory.The accuracy of the model is verified by the radial chuck test bench,and the structural design of the chuck is optimized according to the clamping performance verification results.These simulation and experimental results show that the response time of clamping and loosening with the 3.2 mm disc spring are 0.33 s and 0.35 s,respectively.The leakage of the hydraulic system led to a small deviation in the simulation results,but on the whole,the test results were similar to the simulation response time.The response time of tightening and loosening with the 2.4 mm disc spring are 0.325 s and 0.301 s,respectively.The simulation time is 0.321 s and the test time is 0.326 s.After improved treatment,the improved radial clamping time is close to the chuck,which can meet the requirements of practical application.The test curve is in good agreement with the simulation curve,and the same reaction time is obtained.The results can provide a useful guidance for optimizing the structure of chuck design.
