    • PROBLEM TO BE SOLVED: To measure the surface profile of a steel pipe easily even when there are irregularities on a steel pipe surface to be measured.
      SOLUTION: The template 1 for measuring the surface profile in the circumferential direction of a welded steel pipe includes a pair of legs 2 which are spaced apart from each other in the circumferential direction of the steel pipe and are in contact with the steel pipe surface and a measuring main part 3 which is provided between the pair of legs 2 and has a gap formed with the facing steel pipe surface, which is continuous in the circumferential direction of the steel pipe. A part 3a of the measuring main part 3 facing the steel pipe through the gap has contours in which the gap is a constant value in the circumferential direction of the steel pipe when the steel pipe surface to be measured is a standard ideal curved surface A.

    • 要解决的问题:即使在要测量的钢管表面上存在凹凸,也容易测量钢管的表面轮廓。 解决方案:用于测量焊接钢管的圆周方向上的表面轮廓的模板1包括在钢管的圆周方向上彼此间隔开并与钢接触的一对支脚2 管面和设置在一对支腿2之间的测量主体3,并且具有与钢管的圆周方向连续的面对钢管表面形成的间隙。 测量主体3的通过间隙面向钢管的部分3a具有轮廓,当被测钢管表面是标准理想曲面A时,其间隙在钢管周向上是恒定值。 版权所有(C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a shape data generating device automatically generating the shape data of a profile inspection block for NC machining with high accuracy, based on a work shape model generated by CAD. SOLUTION: This shape data generating device is provided with a shape condition setting means setting the gap, height and depth of a profile inspection block against the ridge line along the edge of an inspection object face on a shape model displayed on a screen, an edge reference point setting means 21 setting three or more edge reference points at both ends of the width of the profile inspection block and splitting between them on the ridge line of the shape model, a three-dimensional tangential line generating means 22 of the edge reference points on the inspection object face of the shape model, an upper face generating means 23 connecting the points separated by a gap from the edge reference points on a three-dimensional tangential line to generate one edge line in the width direction of the upper face of the profile inspection block, connecting the points separated by the depth to form another ridge line, and sweeping multiple regions surrounded by these ridge lines and the three-dimensional tangential line to generate an upper face, a front face generating means 24 forming orthogonal lines to the three-dimensional tangential line from multiple points on one ridge line on the base section side of the profile inspection block and sweeping the multiple regions to form a front face, and a non-inspection face generating means 25 generating the remaining face.
