    摘要： A positive feed tool may include a motor, a gear head and a spindle. The gear head may be operably coupled to the motor and may include a drive assembly and a feed assembly. The spindle may be operably coupled to the gear head and may be selectively driven rotationally and fed axially based on operation of the drive assembly and the feed assembly, respectively. The feed assembly may include a feed rate oscillator having a fixed cam and a movable cam operably coupled to each other via a plurality of rolling elements to oscillate between a maximum width and a minimum width of the feed rate oscillator based on a position of the movable cam. The rolling elements alternate between a first state in which at least some of the rolling elements are unloaded and a second state in which all of the rolling elements are loaded.

    摘要： Some embodiments are directed to an oscillating system including at least one drive motor for driving a spindle about an axis of rotation, a first plate cooperating with a second plate, wherein the first plate is inclined with respect to the axis of rotation, in that the second plate is ball-jointed on a second axis that is offset with respect to the axis of rotation, creating an amplitude of oscillations in the spindle, in that at least one of the two plates is driven by the drive motor, and in that the two plates rotate at different speeds. The combination of the inclination of the first plate and the eccentricity of the center of rotation of the second plate makes it possible to create an oscillation in the spindle while it rotates.

    摘要： A drilling machine of the woodpecker type employs a spindle carrying a drill. The spindle is mounted for rotation in a housing having an attached feed screw and those members form an assembly that can be axially moved while the spindle rotates to enable the drill to be fed toward and retracted away from the work. The feed screw is engaged by a nut whose position is controlled by a rapid traverse mecahnism which can rapidly retract the spindle away from the work and can rapidly advance the spindle toward the work. The rapid traverse mechanism holds the nut fixed in position in the interval between rapid advance and rapid retraction. A peck feed mechanism is connected to the feed screw and repetitively feeds the spindle toward the work by causing the feed screw to progressively advance into the nut in the intervals when the nut is fixed in position. A hitch feed is coupled to the feed screw and acts to prevent the drill from bottoming in the hole on rapid advance. A trigger mechanism is arranged to be fired upon drilling of the hole to a predetermined depth. Upon firing, the trigger mechanism causes the feed screw to be disengaged from the hitch feed and from the peck feed mechanism whereby the feed screw is enabled to return to a starting position relative to the nut.

    摘要翻译： 啄木鸟式钻机采用承载钻机的主轴。 主轴安装成在具有附接的进给螺杆的壳体中旋转，并且这些构件形成在主轴旋转时可以轴向移动的组件，以使得钻头能够朝向工件进给和从工件中缩回。 进给螺杆由螺母接合，螺母的位置由快速移动机构控制，可快速将主轴从工件上收回，并可快速将主轴推向工件。 快速移动机构将螺母固定在快速前进和快速缩回之间的间隔内。 啄进给机构连接到进给螺杆，并且当螺母固定就位时，通过使进给螺杆以间隔的顺序逐渐前进到螺母中，将主轴重复地供给工件。 连接进料联接到进给螺杆，并用于防止钻头在快速进给时在钻孔中触底。 触发机构布置成在将孔钻孔到预定深度时被点燃。 触发机构在触发时使得进给螺杆从连接进给和从进给机构脱离，由此进给螺杆能够相对于螺母返回到起始位置。

    摘要： In one aspect, a swiss-type machine tool is provided that includes a workpiece holding shaft, a workpiece supporting shaft, and a tool holder associated with the workpiece supporting shaft for holding at least one tool. The machine tool includes a drive operable to rotate the workpiece holding shaft and the workpiece supporting shaft around an axis. The workpiece holding shaft has a work holder configured to secure a workpiece to the workpiece holding shaft. The workpiece holding shaft is axially shiftable relative to the workpiece supporting shaft to adjust a position of the workpiece relative to the workpiece supporting shaft. The machine tool further includes a removable workpiece support, such as a guide bushing, configured to be releasably connected to the workpiece supporting shaft and rotate therewith. The workpiece support slidably contacts the workpiece and permits axial movement of the workpiece relative to the workpiece support.

    摘要： A tool driving device for hole processing includes a spindle, an electric motor, a guide, an electric actuator, a sensor and a controller. The spindle has a holder for holding a tool for the hole processing. The holder is disposed at a distal portion of the spindle. The electric motor rotates the spindle. The guide has a positioning member for positioning the tool driving device to the workpiece. The electric actuator advances and retreats the spindle relatively to the guide in a rotation axis direction of the spindle. The sensor measures cutting resistance transmitted from the tool to the spindle. The controller is configured to control the electric motor and the electric actuator based on the cutting resistance measured by the sensor so that a rotating speed and a feeding speed of the spindle become a rotating speed and a feeding speed according to the cutting resistance.
