    • A system for automatically adjusting a fastener screw of a pivot joint between first and second parts of a pair of scissors, each part having a blade and a respective handle. A part clamp engages and holds the handle of the first part. A torque arm engages and moves the handle of the second part relative to the first part about the pivot joint. A driver adjusts the fastener screw to provide a desired resistance to relative movement between the first and second parts. A position encoder is connected to the part clamp and torque arm to generate a position signal indicative of the position of the second part relative to the first part. A torque transducer is connected to the parts clamp and torque arm to generate a torque signal indicative of the resistance to relative movement between the first and second parts. A controller has inputs operatively connected to the position encoder and to the torque transducer and an output operatively connected to the driver. The controller is responsive to the position signal and to the torque signal and controls the driver.
    • 一种用于自动调节一对剪刀的第一和第二部分之间的枢转接头的紧固件螺钉的系统,每个部件具有刀片和相应的手柄。 部件夹具接合并保持第一部件的手柄。 扭矩臂相对于第一部分围绕枢转接头接合并移动第二部分的手柄。 驱动器调节紧固件螺钉,以提供对第一和第二部件之间的相对运动的期望阻力。 位置编码器连接到部件夹紧和扭矩臂,以产生指示第二部分相对于第一部分的位置的位置信号。 扭矩传感器连接到零件夹紧和扭矩臂,以产生表示第一和第二部件之间相对运动阻力的扭矩信号。 控制器具有可操作地连接到位置编码器和扭矩传感器的输入端以及可操作地连接到驱动器的输出端。 控制器响应于位置信号和扭矩信号并控制驾驶员。

    • An actuating drive including an electronically commutated electric motor which operates with a position-dependent summed torque and which, using a torque controller and a controlled system, is able to be adjusted to a selectable, torque-dependent setpoint value according to a continuously increasing torque-time characteristic curve. The torque controller is able to have supplied to it a torque-dependent actual value of the electric motor in addition to the set point value to derive a control signal. A positioning control is subordinate the torque control, the positioning control providing that the minima between the maxima of the summed torque are rapidly and reliably passed and the electric motor is stopped in the region of a maximum.
    • 一种致动驱动器,包括电子换向电动机,其以位置相关的相加转矩运行,并且使用转矩控制器和受控系统能够根据连续增加的转矩将其调节到可选择的与转矩相关的设定值 时间特征曲线。 除了设定值以外,转矩控制器能够向其提供电动机的与转矩相关的实际值,以得出控制信号。 定位控制从属于转矩控制,定位控制使得总和转矩的最大值之间的最小值能够快速可靠地通过,电动机在最大范围内停止。
