20090183380 | CALIBRATION DEVICE FOR NOZZLE AND CALIBRATION METHOD FOR NOZZLE - A calibration device for a nozzle suitable for calibrating a nozzle of a semiconductor apparatus is provided. The semiconductor apparatus includes a chuck with a center hole with radius R | 07-23-2009 |
20100170100 | INTEGRAL ILLUMINATED OPTICAL CENTER FINDER AND MARKING TOOL - Apparatus and methods associated with a center finder and marking tool are disclosed. A center finder and marking tool device includes a base that is configured to be positioned on a work piece surface. The base includes a bore hole. A body is disposed inside the bore hole and rotationally coupled to the base, wherein the body includes a first bore tunnel and a second bore tunnel. An optical center finder is disposed inside the first bore tunnel, and a marking tool is disposed inside the second bore tunnel. | 07-08-2010 |
20120174424 | WORKPIECE CENTERING APPARATUS AND WORKPIECE CENTERING METHOD - The positions of at least three points, which are circumferentially, and equiangularly, offset from each other, of a peripheral face of a workpiece set on a rotary table are measured using a position detection probe. The amount of runout of the axis of the workpiece and a phase position of the workpiece, at which the runout amount is largest, are calculated from the measured positions of the equiangularly offset points. The rotary table is turned to set the largest runout phase position of the workpiece in a position opposed to a workpiece contact of a centering apparatus. The relative positions of the workpiece and a position detection block are calculated using the position detection probe. The workpiece is centered by moving a centering shaft member of the centering apparatus such that the workpiece contact pushes the workpiece by a distance corresponding to the runout amount. | 07-12-2012 |
20120192444 | Method and Device for Locating Hole Center - A device locates an apparatus to the center of a hole in a structure. The device includes a hub adapted to have the apparatus mounted thereon and a plurality of locator elements spaced around the hub which extend at least partially into the hole. Means coupled with the locator elements and the hub are used to displace the locator elements outwardly into engagement with the edges of the structure and to move the hub into axial alignment with the center of the hole. | 08-02-2012 |
20140123510 | METHOD AND APPARATUS FOR MEASURING A MANUFACTURING DEVIATION IN AN EXTERNAL GEAR - Method and apparatus ( | 05-08-2014 |
20140331510 | METHOD FOR MEASURING REFERENCE POINT OF INCLINED ROTATING TABLE IN WIRE ELECTRIC DISCHARGE MACHINE AND MEASURING JIG - A reference point on a table center of an inclined rotating table in a wire electric discharge machine is obtained using a measuring jig. A biaxial rotation unit is placed on a table of the wire electric discharge machine. The measuring jig has a shape most suitable for reference point measurement using a contact sensing function of a wire electrode which a wire electric discharge machine generally has and includes a fixed section for being fixed to a work fixing section of the biaxial rotation unit, an arm section which is provided to stand on the fixed section, and a section to be measured which is provided at a distal end of the arm section and has a conductive spherical surface. | 11-13-2014 |
20160138901 | FIXTURE FOR MEASURING CENTER POSITION OF ROTATION SHAFT AND METHOD FOR MEASURING CENTER POSITION OF ROTATION SHAFT USING THE SAME - A rotation table, center position of a rotation shaft of which is to be measured, is mounted on a table of a machine tool and includes a turning plate on which a workpiece is placed, a rotary drive for rotating the turning plate, and a rotation shaft support device that is located opposite the rotary drive and supports the turning plate. A fixture, including a rod-like member that is provided with spherical reference bodies at both ends and is disposed on the turning plate of the rotary table, is used to measure the center position of the rotation shaft of the rotary table. | 05-19-2016 |
