    • A conventional stud welding tool is substantially improved by providing the tool with an electrode with an adjustable aperture capable of grasping studs with a variety of sizes. The adjustable aperture is in the form of a chuck having a plurality of sliding fingers movable along intersecting axes and positionable along these axes to form an aperture of a desired diameter. The fingers have a threaded exterior surface, and the chuck includes a wheel having a threaded interior surface for engaging the threaded exterior surfaces of the fingers for moving the fingers along their axes in response to rotation of the wheel. The chuck is automatically closed and opened by a control circuit in response to the condition of a variety of sensors connected to the control circuit. Also, a collating strip of studs and a feed assembly is used to automatically deliver studs to the electrode under control of the control circuit.
    • 通过为工具提供具有能够抓住各种尺寸的螺柱的可调节孔的电极,实质上改进了传统的螺柱焊接工具。 可调整孔径为卡盘形式,其具有可沿着相交轴线移动并可沿这些轴线定位的多个滑动指,以形成所需直径的孔。 手指具有螺纹外表面,并且卡盘包括具有螺纹内表面的轮,用于接合手指的螺纹外表面,以响应于轮的旋转而沿着其轴线移动指状物。 响应于连接到控制电路的各种传感器的状况,卡盘由控制电路自动关闭并打开。 此外,螺柱和进给组件的整理条被用于在控制电路的控制下自动地将螺柱输送到电极。
