Abstract:
The apparatus of measuring a workpiece according to the present disclosure includes a base, a measuring member, an upper arm member, a lower arm member, a first pin and a second pin, wherein the upper arm member includes an upper rotation frame and the lower arm member includes a lower rotation frame. When the first pin is moved to disconnect the upper rotation frame from the lower rotation frame, the upper rotation frame is rotatable. When the second pin is moved to lock the lower rotation frame to the measuring member, the lower rotation frame is free of rotation. When the first pin is moved to connect the upper rotation frame and the lower rotation frame with each other and when the second pin is moved to unlock the lower rotation frame from the measuring member, the lower rotation frame is rotatable with the upper rotation frame.
Abstract:
A system (12) for measuring geometry of a non-circular twisted strand (10) during a stranding process, the system comprising: a pulley (14), for being rotated by linear displacement of the strand (10) induced by the stranding process; a first encoder (16), for measuring the rotation of the pulley (14), thereby measuring the linear displacement of the strand (10); at least one embracing element (36), for embracing a vertex (38) or another zone (48) of the strand (10), for being rotated perpendicular (60) to the longitudinal position (58) of the strand (10), the embracing obtained by the non-circular character of the strand (10) rather than by friction, thereby allowing sliding the at least one embracing element (36) therealong; and a second encoder (20), for measuring the rotation of the at least one embracing element (36), thereby measuring the twist character of the strand (10).
Abstract:
A two way roundness device can be configured as a device in which a tool, such as an indicator rotates or as a device in which the part to be measured or cut rotates. This ability to alternate between these two configurations is enabled by a combination of a rotating spindle assembly and a two-axis stage that can be oriented, in use, with the two-axis stage under the spindle assembly or with the two-axis stage on top of the spindle assembly.
Abstract:
An apparatus for revealing the geometry of operative cylinders, in particular during the grinding operation of the same, includes a pair of movable clamps which can be moved away from and towards each other with respect to a fixed intermediate structure, the clamps having tilted surfaces in opposite directions to each other according to a swallowtail arrangement with respect to a cylinder being measured, positioned between them and between a surface of the fixed intermediate structure, the surfaces of the movable clamps and the surface of the fixed intermediate structure always being kept in contact with the cylinder, whether still or rotating, wherein the fixed structure also has, in its interior, parts of a group which interact with each other to correlate the movement of the clamps.
Abstract:
A roundness measuring apparatus includes a stylus stocker and a controller. The stylus stocker stores plural types of styli prepared corresponding to shapes of measurement sites of a measurement target object. The stylus stocker can store styli in such a manner that each stylus can be held thereon and taken out thereof. The stylus stocker is provided outside a measurement region, which is determined on the basis of the operation range of a turntable and a detector driving mechanism. The detector driving mechanism can move the detector to the outside of the measurement region. When a measurement command is given, the controller carries out roundness measurement of the object while controlling the turntable and the detector driving mechanism. When a stylus replacement command is given, the controller carries out stylus replacement operation between a detector main unit and the stylus stocker while controlling the detector driving mechanism.
Abstract:
A method of calibrating a surface texture measurement device includes obtaining Y-axis shape measurement data and a maximum diameter portion to obtain upper and lower maximum diameter portions of a reference sphere from Y-axis upper and lower shape data obtained by relatively moving in the Y-axis direction while a downward and an upward styluses are in contact with an upper and a lower surfaces, respectively, of the reference sphere; obtaining X-axis shape measurement data to obtain X-axis upper and lower shape data of the reference sphere by relatively moving in the X-axis direction while the downward stylus is in contact with the upper diameter portion and the upward stylus with the lower diameter portion of the reference sphere; and calculating offset amounts Δx and Δz of the upward and downward styluses from center coordinates O3 and O4 obtained from the shape data.
Abstract:
A system includes at least one body, a link for suspending the body for movement with gravity from a first elevation position to a second elevation position, and an electrical energy generator coupled with the body through the link to drive the generator to generate electricity upon movement of the body with gravity from the first to the second elevation position. The at least one body has a mass of at least approximately 100 tonnes; the first and the second elevation positions define a distance therebetween of at least approximately 200 meters; and/or the system further includes an operator configured to operate the link to controllably move the at least one body against gravity from the second to the first elevation position to increase a gravitational potential energy of the at least one body, and to maintain the gravitational potential energy of the at least one body.
Abstract:
According to the present invention, a center deviation amount, which is an amount of deviation (distance) between the center line of a reference measurement target and the detection point is calculated using the reference measurement target having a known diameter, and a measurement value of a diameter of an arbitrary measurement target is corrected using the center deviation amount. Therefore, an accurate diameter value can be calculated even in the case of a measurement target having a diameter value different from the diameter value of the reference measurement target.
