    摘要: A wheel-head feed mechanism for a grinder comprising a base and a wheel head which is guided by a linear guide section provided on the base and rotatably supports a grinding wheel via a wheel spindle driven by a motor. The wheel-head feed mechanism includes feed screw mechanism composed of a screw shaft and a nut unit engaged with the screw shaft, the feed screw mechanism advancing and retracting the wheel head with respect to a workpiece, and servomotor for rotating one of the screw shaft and the nut unit. The screw shaft is offset from the linear guide section toward the wheel spindle. The nut unit includes a radial hydrostatic bearing section for supporting the root of a male thread of the screw shaft in the radial direction of the screw shaft by hydrostatic pressure, as well as a thrust hydrostatic bearing section for supporting the flanks of the male thread of the screw shaft in the axial direction of the screw shaft by hydrostatic pressure.

    摘要: A feed screw mechanism includes a nut having a female thread, and a feed screw shaft having a male thread screw-engaged with the female thread. A thrust pocket is formed along a flank of the female thread of the nut, and pressurized fluid is supplied thereto. A plurality of separated radial pockets are formed on the crest surface of the female thread of the nut, and pressurized fluid is supplied thereto. The thrust pocket is a continuous spiral groove formed along the flank of the female thread of the nut. This structure provides sufficient rigidity in both the radial and thrust directions while reducing the size of the feed screw mechanism.

    摘要: A machining spindle apparatus has a hydrostatic bearing for machine tools. The machining spindle apparatus includes a built-in motor built into the middle of a housing, as well as front and rear hydrostatic bearings respectively mounted on the front side and the rear side of the housing. A machining spindle is driven by the built-in motor and rotatably supported by the front and rear hydrostatic bearings. The front hydrostatic bearing comprises a radial bearing pocket and a thrust bearing pocket. In addition, a pair of pneumatic seals lie over the radial and thrust bearing pockets. The rear hydrostatic bearing includes a radial bearing pocket and a constant-pressurized oil chamber. The constant-pressurized oil chamber operates as a piston cylinder. Accordingly, a predetermined pressure acts forward, i.e. opposite the thrust bearing pocket of the front hydrostatic bearing. And another pair of pneumatic seals lies over both of the radial bearing pocket and the constant-pressurized oil chamber.

    摘要: A beam collecting device and a laser emission device are disclosed incorporating a laminated optical waveguide array and refraction means therein. The laminated optical waveguide array is composed of a plurality of plate-like optical waveguides made of a material having a predetermined refractive index and a plurality of spacer members having a lower refractive index than that of said optical waveguides and arranged alternately with said optical waveguides. The spacer members take the form of cylindrical members, spherical members or plate-like members. The beam collecting device and laser emission device comprise a semiconductor laser array having a plurality of laser emitting parts arranged in fast and slow axis directions, the optical waveguide array, optical fibers and a collective lens. The laser emitting parts are divided into plural groups separated in the slow axis direction. Each of the optical waveguides collects plural laser beams from the laser emitting parts of a corresponding group aligned in the fast axis direction to an emission surface thereof and emits them to a corresponding one of the optical fibers. The refraction means is provided at the emission surface of each waveguide, at an incidence surface of each optical fiber or therebetween, so that the laser beam emitted from the emission surface of the waveguide at an acute angle is refracted to enter into the optical fiber at a gentle angle. Thus, laser beams entered into each optical fiber, without shining therethrough, are efficiently collected to the collective lens to be emitted to a target position.

    摘要: A shape measuring instrument is provided as being capable of measuring a surface shape of a target with a small contact force while changing the contact force. A measuring probe 32 is supported while a tilt θ is provided. A retracting force of the measuring force 32 is produced by the tilt θ, and thus, is obtained as mgsig θ which is much small as compared with a self weight “m”. On the other hand, biasing is provided with an extruding force Fc by means of an air cylinder 40. Thus, a contact force of the measuring probe 32 relevant to a work piece W is obtained as a difference between a measuring probe self weight tilt component mgsigθ and the extruding force Fc of the air cylinder 40 (F=Fc−mgsigθ), thus making it possible to reduce a contact force to be very small.

    摘要: An apparatus for measuring a circularity deviation of a cylinder of an object intended to be integrally rotated about a rotation axis, the cylinder being eccentric as either intended or not with the rotation axis, the apparatus includes a measuring device, a motion controlling mechanism, and a circularity deviation calculating device. The measuring device is adapted to measure a circumferential surface of the cylinder at each measuring point “p” thereon in a three-point contact method. The motion controlling mechanism is configured to permit the measuring device to be moved along a circumference of the cylinder, which circumference lays on a cross section of the cylinder perpendicular to the rotation axis, in contact with the circumferential surface of the cylinder, during rotation of the cylinder about the rotation axis. The circularity deviation calculating device is designed to calculate the circularity deviation of the cylinder, on the basis of a relative position “x” of the rotation axis relative to the apparatus for measuring the circularity deviation, a rotating angle &phgr; of the cylinder about the rotation axis, and an output “y” of the measuring device.

Ther feed mechanism includes a ball nut assembly threadedly coupled with the feed screw shaft, and a floatably supporting member for floatably supporting the ball nut assembly. The floatably supporting member is composed of a board having a predetermined thickness in a direction parallel to the rotational axis of the feed screw shaft. The floatably supporting member is formed with plural slots penetrating the floatably supporting member in a direction parallel to the axis of the feed screw shaft so as to form a fixed portion, a first floating portion, first flexible connecting portions which support the first floating portion for movement relative to the fixed portion in a first direction perpendicular to the axis of the feed screw shaft, a second floating portion, and second flexible connecting portions which support the second floating portion for movement relative to the first floating portion in a second direction perpendicular to the axis of the feed screw shaft and the first axis. The ball nut assembly is secured to the second floating portion of the floatably supporting member.
