A steel plate positioning sampling scale, comprising a sampling mould (2), a positioning scale (4), a pull rod (3), a slide block and a pin shaft, wherein the sampling mould (2) is of a square structure; one end of the positioning scale (4) is provided with a slide groove, and positioning scales (7) and angle scales (6) are marked on two sides of a positioning scale slide groove (5); the sampling mould (2) is hinged with the positioning scale (4) and the pull rod (3) by means of the pin shaft, the positioning scale (4) is connected to the pull rod (3) by means of the slide block, and one edge of the sampling mould (2), the positioning scale (4) and the pull rod (3) form an isosceles triangle; by moving the positioning scale (4), a distance from the sampling mould (2) to the edge of a steel plate can be determined, by sliding the pull rod (3), the length of a bottom edge of the isosceles triangle can be changed, an included angle between the sampling mould and the positioning scale is further changed, and the requirement on sampling on different positions and angles of the steel plate can be met. |
