摘　　要：旋入式底火装配过程中常用的扭矩控制方式由于扭矩控制环响应周期太长、控制精度不高容易产生过拧现象,导致底火跳坑划伤及拧紧工装受损。针对上述问题,改进了扭矩控制环硬件平台,采用更高响应频率的扭矩实时限幅控制拧紧方式对拧紧装配过程的拧紧头扭矩输出进行控制。应用结果表明,采用该控制方式,大大提高了终紧阶段的扭矩控制精度,避免了扭矩超调,实现了防过拧的底火拧紧连接装配。Torque control method is usually used in screw-in primer assembly, which may result in excess tighten because of the long response of its torque control ring, thus lead to error wrench scratch and screw device damage. Aiming at these problems, we mended hard platform of the torque control ring and adopted a screw method with real-time clipping control of higher response frequency to command tappet head torque output during tighten and assembly. Result shows the method can greatly advance torque control precision in the process of last tighten, while avoid excess torque adjustment and achieve excess tighten prevention in primer screw up, linkage and assembly.
