摘　　要：针对某多工艺集成卧式数控旋压加工中心尾座的使用要求,设计了一种方便快捷、具有较好的对中性及稳定性的尾座结构。基于电液联合控制方法,建立了一套可提供稳定尾顶力且能实现“快进-工进-快退”运动的尾座液压系统,可确保旋压过程顺利进行。借助SimulationX软件构建了旋压成形实际工况下的尾座液压系统仿真模型,对尾顶运动位移、速度及系统压力、尾顶力进行了仿真。仿真获得的尾顶快进、快退速度与试验结果的误差分别为3.94%和7.50%;仿真获得的系统压力、尾顶力与理论结果的误差分别为5%和0.4%,验证了仿真模型的准确性及液压系统的可靠性。For the requirements of a horizontal CNC spinning machining center with multi process integration,a convenient and efficient tailstock structure with good neutrality and stability was designed,and the tailstock hydraulic system providing stable tail force and realizing the fast feed-working and feed-fast retract was established by the electro-hydraulic control method to ensure the spinning process running smoothly. Then,its tailstock hydraulic system simulation model during actual spinning forming was built by software Simulation X,and the tail displacement,speed,system pressure and tail force were simulated. Furthermore,the relative error of the fast feed and fast retract between the simulation results and experimental results are only 3. 94% and 7. 50% respectively,and the relative error of the system pressure and tail force between the simulation results and theoretical results are only 5% and 0. 4% respectively. Thus,the accuracy of simulation model and the reliability of hydraulic system were verified.
