    摘要： A pull bar gripper assembly having a body member with a pusher slidably mounted thereon arranged to engage the end of a workpiece to be pulled. A collar is connected to the pusher. A pair of gripper arms, each having a gripping pad connected on one end thereof, are pivotally mounted on the body member. A toggle link interconnects the other end of each gripper arm to the collar and a coil spring normally biases the pusher toward an inoperative or non-gripping position. In operation, the gripper arms are pivoted into gripping position onto a workpiece as the gripper assembly is advanced toward the workpiece by the retraction of the pusher upon engaging the end of a workpiece. In doing so, the toggle link compressing the coil spring shifts through dead center to lock the gripping pads onto the workpiece. Release is effected by pulling the gripper assembly away from the workpiece slightly, causing the coil spring to return the pusher and gripper arms to their normal inoperative or non-gripping position.

    摘要翻译： 拉杆夹具组件，其具有主体构件，其具有可滑动地安装在其上的推动器，其布置成接合待拉动的工件的端部。 衣领连接到推杆。 一对夹持臂，其一端具有连接在其上的夹持垫，可转动地安装在主体构件上。 肘节连杆将每个夹持臂的另一端连接到轴环上，并且螺旋弹簧通常将推动器朝向不操作或非夹紧位置偏压。 在操作中，当夹持器组件在与工件的端部接合时通过推动器的缩回而朝向工件前进时，夹持臂枢转到夹持位置到工件上。 在这样做时，压缩螺旋弹簧的肘节连接件通过死角移动，以将夹紧垫锁定在工件上。 通过将夹具组件稍微拉离工件来实现释放，使得螺旋弹簧将推动器和夹持臂返回到其正常的非操作或非夹紧位置。

    摘要： A bar stock feed tube assembly is disclosed of the type in which bar feed stock is supported and guided by, and rotates within, the assembly during machining. The feed tube assembly is comprised of an anechoic feed tube, a surrounding reinforcing jacket, and an intermediate, acoustically-decoupling layer of energy-absorbing material. Retaining caps are provided at the ends of the assembly to protect the end of the anechoic feed tube and its jacket, to act as a stop against axial movement of the assembly, and to retain the feed tube within the reinforcing jacket. By utilizing retaining caps having feed stock-receiving orifices of smaller diameters than the feed tube, the assembly may be adapted for use with a wide range of bar stock sizes.

    摘要： An adjustable support for supporting bar or tube stock serving a turning machine spindle or feeder or stock support tube or the like. It includes a tube having therethrough a through-opening of infinitely variable diameter concentric with the tube center line and coincident with the work centerline of the served unit. The tube accommodates along its length a plurality of stock-supporting sections and at least one elongated longitudinally extending pusher-puller bars. Each such section is defined by a pair of pushers and a pair of opening-defining stock-supporting rings. The pushers and rings of each pair are mounted in spaced alternating disposition along the tube length. Each ring has a pair of diametrically-opposed oppositely-facing tongues, each extending outwardly from one of its sides. The rings of the pair are trunnion mounted relative to the tube with their axes disposed 90.degree. apart, and are swingable unisonly between an opened stock-non-supporting position and myriad closed stock-supporting positions. In opened position, they define a tube-through-opening of maximum diameter, and in closed positions, they define a tube-through-opening of less than maximum diameter as determined by the projection of the tongues inwardly toward the tube centerline. The diameter is variable in indirect ratio with the degree of ring angularization -- the greater the angularization, the smaller the through-opening. The pushers are fixed to the pusher-puller bar or bars so as to be movable in opposite directions lengthwise of the tube. As the pusher-puller bars and pushers are driven in one direction, each pusher is moved into a contacting relationship with a respective ring, the pusher pushing its ring in a swinging through-opening defining movement on its respective axis and a supporting embracement of each tongue with the stock periphery and as driven in counter direction a connector between each pusher and its respective ring pulls the rings away from non-stock supporting positions.

    摘要： A bar holder and feeder for an automatic machine tool comprising an elongated bar holder aligned with the machine tool, which bar holder can be opened to allow bar to be loaded thereinto; loading means to load bar into a loaded position in the bar holder; and a bar feeder positioned between the elongated bar holder and the machine tool, through an open collet of which machine tool bar is to be fed from the bar holder, the bar feeder comprising a sleeve engageable over a bar to be fed at a position externally of the machine tool and feed means to cause axial movement of the sleeve, the sleeve having internal biased gripping means which permit the sleeve to be moved by the feed means over the bar in a direction away from the machine tool but prevent the sleeve being moved by the feed means over the bar in a direction towards the machine tool, whereby a reciprocation of the sleeve by the feed means causes the bar to be fed to the machine tool, and means to prevent movement of the bar from the loaded position in a direction away from the machine tool to enable the sleeve initially to be pressed over the end of the bar nearer the machine tool or means to move the bar towards the machine tool initially to engage the end of the bar nearer the machine tool in the sleeve.The loading means may include a pair of jaws which can grip the bar in the loaded position and prevent movement of the bar away from the machine tool. The feed means may comprise a slide, with which the sleeve can be entrained, movable towards and away from the machine tool by a suspended weight and/or piston/cylinder arrangement.

    摘要： A bar feed for a rotary spindle lathe is provided with an arrangement for positively guiding the rear end of the bar being fed without interfering with its longitudinal motion. The bar feed arrangement includes a pair of V-shaped guide rails defining a guide diameter the same as the bore through the spindle. A feed rod is guided in the channel by a collar at each end, with the rear collar being non-rotatably secured to the feed rod and the front collar being rotatably journaled on the feed rod and also rotatably journaled with respect to the bar stock gripping collet so that it may be selectively rotatable or non-rotatable depending upon whether it is in the guide channel or the lathe spindle.
