Furthermore, the two scale marks of the judging area are respectively a first scale mark and a second scale mark, the judging area is formed between the first scale mark and the second scale mark, the transparent judging plate is further provided with a starting scale mark, the starting scale mark is overlapped with the edge tangent line of the positioning hole, and the distances between the first scale mark and the starting scale mark and the distance between the second scale mark and the starting scale mark are respectively the qualified distances of the edges at the two ends of the mounting hole.
Furthermore, the transparent judgment plate is of a rectangular structure, so that the formation of scale marks is facilitated.
Furthermore, the transparent judging plate is an acrylic transparent judging plate, and the acrylic transparent judging plate not only has good transparency, but also cannot cause pollution to the plane plate.
The utility model discloses in utilize transparent judgement board through whether falling into the audio-visual judgement testing result of the mode of judging the region, the mode of current direct measurement and calculation interval has been replaced, the error range direct consideration of interval and reflection are judging in the region, through the matching effect of locating hole and one of them mounting hole, the positioning action to transparent judgement board has been played, because the transparency of transparent judgement board, whether can audio-visual judgement another mounting hole is in judging the region, with this realization to the accurate judgement of mounting hole interval.
Has the advantages that: compared with the prior art, the utility model, possess following advantage:
1. the whole detection operation is simple, direct and effective, and the detection personnel can directly obtain a judgment result in the detection operation, so that the detection efficiency is greatly improved, and the mass production of the LNG marine plane plate is very facilitated.
2. Whether the mounting hole is located in the judging area or not is used for obtaining a judging result, and measuring errors existing in the existing detecting mode are eliminated, so that the accuracy of the detecting result is ensured, and the subsequent using effect of the plane plate is ensured.
