    • A light weight servo controlled robot gripper is disclosed. A plastic body houses one or more threaded drive shafts which are powered by a direct current motor. Attached to the shafts are finger mounting blocks which support removable fingers and which can be driven both closer to and further away from a fixed point by the motor. Integral with at least one mounting block is a force transducer which monitors the load exerted on the finger through a pivot and lever action of a mounting bracket provided adjacent to the load cell. Since the transducer is in the block rather than the fingertip, fingers are readily interchangable without reinstrumentation. A limit switch, located above one of the finger mounting blocks, is used to determine coarse finger position, and an optical shaft encoder provides precise position information allowing the gripper to be utilized for a variety of position as well as force servoing tasks.
    • 公开了一种重量轻的伺服控制机器人夹持器。 塑料体容纳由直流电动机驱动的一个或多个螺纹驱动轴。 连接到轴上的是手指安装块,其支撑可移除的手指,并且可以通过马达被驱动到更靠近并远离固定点。 与至少一个安装块成一体是力传感器,其通过邻近测力传感器设置的安装支架的枢轴和杠杆作用来监视施加在手指上的负载。 由于换能器在块而不是指尖,手指易于互换而不进行重新装置。 位于手指安装块上方的限位开关用于确定粗指位置,光轴编码器提供精确的位置信息,允许夹持器用于各种位置以及强制伺服任务。

    • A pneumatic anode positioning apparatus is disclosed for positioning any number of a plurality of anodes relative to a cathode in an electrolytic cell. This apparatus comprises a means for determining the desired anode position for each of the anodes and converting the amount of movement necessary to attain such position to a number of increments of predetermined displacement. The apparatus has a pneumatic, bidirectional drive means for incrementally rotating a substantially horizontally disposed shaft, a plurality of vertically disposed jack screws each connected to an anode or anodes and provided with means therebetween for changing incremental rotary motion to incremental, vertically longitudinal anode motion, a plurality of worm gears connected at their outer periphery to the shaft and at their inner periphery to an actuator nut disposed concentrically about a top portion of the jack screw, and pneumatic means for selectively engaging each actuator nut to its respective jack screw to rotate the jack screw incrementally in response to the incremental rotary movement of the shaft, the engaging means being responsive to the means for determining the desired anode position.
    • 公开了一种用于在电解池中相对于阴极定位任意数量的多个阳极的气动阳极定位装置。 该装置包括用于确定每个阳极的期望的阳极位置的装置,并且将实现该位置所需的移动量转换成预定位移的数量的增量。 该装置具有气动双向驱动装置,用于逐渐地旋转基本上水平设置的轴,多个垂直设置的千斤顶螺钉,每个连接到阳极或阳极并在其间设置有用于将增量旋转运动改变为增量的垂直纵向阳极运动的装置, 多个蜗轮在其外圆周处连接到轴并且在其内周边处连接到围绕千斤顶螺丝的顶部同心地设置的致动器螺母,以及气动装置,用于将每个致动器螺母选择性地接合到其相应的千斤顶螺杆,以使 千斤顶响应于轴的增量旋转运动而递增地旋转,接合装置响应于用于确定期望的阳极位置的装置。
