    • The screw tightening control system includes plural screw tightening apparatuses, and a control apparatus that sets a synchronization point after completion of changing tightening torques of the plural screw tightening apparatuses in a current step, and starts changing of the tightening torques of the plural screw tightening apparatuses in a next step, step by step from the synchronization point. The control apparatus causes a timing to start the changing of the tightening torque of at least one of the plural screw tightening apparatuses from the synchronization point to differ from a timing to start the changing of the tightening torque of at least another one of the plural screw tightening apparatuses. The system controls the plural screw tightening apparatuses while synchronizing them so as to avoid the inconveniences in a conventional art by a simple method.
    • 螺杆紧固控制系统包括多个螺钉紧固装置,以及控制装置,其在当前步骤中,在多个螺钉紧固装置的紧固扭矩变化完成之后设定同步点,并且开始改变多个螺钉紧固装置的紧固扭矩 在下一步中,从同步点一步一步。 控制装置使得从同步点开始改变多个螺杆紧固装置中的至少一个的紧固扭矩的定时与开始改变多个螺杆中的至少另一个的紧固扭矩的时间不同 紧固装置。 该系统同时控制多个螺丝紧固装置,以便通过简单的方法避免常规技术中的不便。
