摘要： An eyeglass frame shape measurement device includes an optical measurement unit, a probe unit, a holding unit that holds the optical measurement unit and the probe unit, a changing portion that integrally moves the optical measurement unit and the probe unit with respect to an eyeglass frame to change a measurement position with respect to a groove of a rim of the eyeglass frame, and a controller that controls an operation of the eyeglass frame shape measurement device. The controller controls an operation of the changing portion to measure the groove of the rim of the eyeglass frame, acquires a cross-sectional shape of the groove of the rim of the eyeglass frame based on a detection result detected by the optical measurement unit, and acquires a shape of the rim of the eyeglass frame based on a detection result detected by the probe unit.

摘要： Disclosed is a device for the inspection or maintenance of devices, for example rotor blades of wind power plants. A frame structure can encompass the device, e.g. a rotor blade, and be used for the inspection or examination or cleaning of the rotor blade or other object. The frame structure has, for example, an inner opening which encloses the object during use. Propellers allow a horizontal movement of the frame structure and thus, for example, of a robot for examining the object. A vertical movement of the robot can be controlled by a cable suspension so that the vertical position of the examination device can be changed. A detection, cleaning, or monitoring system can be provided on the frame structure for detecting the condition of the object, cleaning, monitoring or treatment. A control station can be provided on the ground or on a transporter or other device.

摘要： A roundness measuring machine includes: a turntable on which a workpiece is to be placed; a displacement detector detecting a displacement of a stylus; a column provided on a base shared with the turntable; a Z-axis slider supported by the column and movable in a Z-axis direction extending vertically; an X-axis slider supported by the Z-axis slider and movable in an X-axis direction intersecting the Z-axis direction; and an attitude adjusting mechanism provided to the X-axis slider and supporting the displacement detector such that an attitude of the displacement detector is adjustable. The attitude adjusting mechanism includes: a Y-axis slider supported by the X-axis slider and movable in a Y-axis direction intersecting the Z-axis and the X-axis directions; and a detector holder supported by the Y-axis slider and supporting the displacement detector such that the displacement detector is turnable around the X-axis direction.

摘要： A computer-implemented method for determining a two-point size of a workpiece includes receiving a set of measuring points of the workpiece, determining a longitudinal axis of the workpiece based on the set of measuring points, projecting at least a part of the set of measuring points into a projection plane perpendicular to the longitudinal axis to obtain a set of projection points, and determining a two-point size of the workpiece based on the projection point.

摘要： A complex surface three-coordinate measuring device includes a three-degree-of-freedom motion platform and a force control probe, the force control probe is fixedly mounted on the Z-axis sliding block, which is in the same direction as the X-axis direction and used to contact with the workpiece surface with constant force. A six-axis force sensor is used to collect the contact force between the stylus and the workpiece surface. In this method, the force control is realized in the measurement to make the stylus in constant force contact with the workpiece surface. The error compensation direction is determined according to the direction of the contact force, and then the effective radius of the stylus spherical head is compensated in this direction, thus the actual contact point of stylus and workpiece can be obtained.

摘要： A method for calculating eccentricity of rotor assembly axis based on radial runout measurement comprises matrix characterization of data and calculation of relative runout value at each point, establishment of a spring equivalent model and calculation of contact force, eccentric direction and magnitude; calculation of relative runout value; establishment of a spring equivalent model to analyze the relationship between force and displacement in each phase of a contact process, and then an uneven contact force at each point is obtained; and determination of eccentricity is to determine the magnitude of eccentricity. Based on the measured radial runout data in production practice, this method realizes the prediction of eccentricity of axis before assembly, improves the coaxiality of rotors after assembly, and has important practical guiding significance for axis prediction as well as assembly phase adjustment and optimization in the assembly process of aero-engine rotor pieces.

摘要： A planning tool plans movement of a boring tool for an underground drilling operation. The planning tool includes one or more wheels for rolling on a surface of the ground along a path responsive to movement by an operator to characterize the surface contour and to generate guidance for the boring tool to reach a target position. Surface roughness is measured based on instantaneous rate of change of an accelerometer output. Accelerometer cross axis sensitivity compensation provides for more accurate surface contour characterization for paths that are not smooth. Accuracy of rolling datasets is predicted and associated indications are presented based on surface roughness in combination with speed. A rumble/speed gauge guides operator movement based on detected surface roughness in combination with speed.

摘要： A pipeline profiler includes an elongated body and a plurality of mechanical arms projecting radially about the elongated body. Each mechanical arm has an adjustable angle bracket shape and a hinge joint formed at a corner of the adjustable angle bracket shape. Odometers to measure a travel distance of the elongated body are coupled to the mechanical arms at the hinge joints of the mechanical arms. Motion devices are coupled to the elongated body to detect the azimuth and inclination of the elongated body. To obtain a profile of a pipeline, the pipeline profiler is attached to a pig that is movable through the pipeline by a fluid pressure in the pipeline.

Methods can further comprise extending a probe to contact a location of the edge portion of the product while the product is clamped to the base. Methods can further comprise determining a height of the edge portion of the product based on the position of the probe contacting the edge portion of the product.
