TIRE MOLD ENGRAVING INSPECTION METHOD AND DEVICE |
摘要 |
A method and a device for inspecting engravings in a tire mold capable of determining the suitability of engravings formed on a surface of an annular side plate, which is a component of the tire mold, in a reduced time and with high precision. The method comprises the steps of:
inputting in advance into a data processing device (2) two-dimensional image master data (9) of an engraving (8) formed on a surface (7a) of a side plate (7) in a plan view using basic data set as a reference, the image master data (9) having a radial component (t) and a radial position (r) of the engraving (8) corrected on the basis of a locus length in a radial direction of the surface (7a) of the side plate (7);
generating two-dimensional image actual measurement data, the image actual measurement data having a radial component and a radial position of three-dimensional data acquired via actual measurement corrected on the basis of a radial locus length of a surface (7a) of a side plate (7) on which actual measurement was performed; and
determining whether or not an image shape and an image position of the image actual measurement data (10) is within a tolerable range via comparing image contours of the image master data (9) and the image actual measurement data (10) by the data processing device (2). |
