    • The spot welding electrodes are driven by the servomotor (30) so as to be moved to and pressured against a work surface. The welding pressure controller (27) detects welding pressure corresponding to current flowing through the servomotor (30) via a driver (26) and controls the welding pressure so as to be changed according to the set welding pressure condition. The welding current flowing through the spot welding electrodes is controlled by the welding current controller (28). The welding current controller (28) and the welding pressure controller (27) are both controlled synchronously by the robot CPU (20) via the system bus (21). The robot CPU (20) controls the welding pressure and the welding current on the basis of the welding condition data (22) stored in a memory, so as to be changed in synchronism with each other at a plurality of welding stages, respectively. By doing this, it is possible to control the welding pressure and the welding current during the spot welding synchronously and systematically, thus realizing a spot welding control adaptive to work behavior.
    • 点焊电极由伺服电动机(30)驱动,以便移动并压靠工作表面。 焊接压力控制器(27)经由驱动器(26)检测与流过伺服电动机(30)的电流对应的焊接压力,并根据设定的焊接压力条件控制焊接压力。 流过点焊电极的焊接电流由焊接电流控制器(28)控制。 焊接电流控制器(28)和焊接压力控制器(27)均由机器人CPU(20)经由系统总线(21)同步控制。 机器人CPU(20)基于存储在存储器中的焊接条件数据(22)来控制焊接压力和焊接电流,从而分别在多个焊接阶段彼此同步地改变。 通过这样做,可以同步,系统地控制点焊期间的焊接压力和焊接电流,从而实现适应工作行为的点焊控制。

    • An elevator rod is passed through a hollow post. A lower cymbal is mounted on the upper end of the post, while an upper cymbal is mounted on the upper portion of the rod. The elevator rod is urged upward by a return spring. A running pulley is mounted on the lower end portion of the rod. The running pulley is rotatable around a horizontal support shaft. A foot board is disposed at a position lower than the pulley, and a flexible member is wound around the pulley. A fixed end of the flexible member is connected to a supporting portion which is situated lower than the running pulley. A free end of the flexible member is connected to the extreme end portion of the foot board.
    • 电梯杆通过中空柱。 下钹安装在柱的上端,而上钹安装在杆的上部。 升降杆由复位弹簧向上推动。 行程滑轮安装在杆的下端部分上。 运行滑轮可绕水平支撑轴旋转。 脚板设置在比滑轮低的位置处,并且柔性构件缠绕在滑轮上。 柔性构件的固定端连接到位于行进滑轮下方的支撑部分。 柔性构件的自由端连接到脚踏板的前端部分。
