[0029] The utility model will be explained in detail in combination with the drawings and specific embodiments.
[0030] The utility model discloses a steel weight deviation size measuring device, like Figure 1As shown, it comprises a sample tube 20 and a clamping head 30; the sample tube 20 is used for containing the steel sample 10; the sample tube 20 is a tubular with one end open and the other end closed, and the inner surface of the closed end of the sample tube 20 is a plane; the clamping head 30 is columnar, and the front end of the clamping head 30 has a fitting surface 33 which is a plane; the sample tube 20 is provided with a scale 21; and the clamping head 30 is provided with an identification mark which is located on the plane where the fitting surface 33 is located.
[0031] The utility model discloses a sample tube 20 can contain steel sample 10, and the one end of steel sample 10 is fitted with the inner surface of the closed end, and the other end is fitted with the fitting surface 33 of clamping head 30, can position the two end faces of steel sample 10, and then the length of steel sample 10 can be read through the identification mark on the clamping head 30 and the scale 21 on the sample tube 20, can reduce the error generated by manual operation when directly measuring, thereby improving the measuring accuracy.
[0032] The sample tube 20 in the utility model can be formed by processing a steel pipe, is convenient to obtain materials and simple to manufacture. Specifically, a steel pipe with a diameter close to that of the steel sample 10 to be measured can be selected, so as to reduce the shaking amplitude of the steel sample 10 in the pipe and reduce the operation difficulty.
[0033] The starting point of the scale 21 is located on the plane where the inner surface of the closed end of the sample tube 20 is located; and the length of the scale 21 is greater than the length of the steel sample 10. For example, the length of the steel sample 10 is usually 500 mm, and the scale can be designed to be 450-550 mm or 400-600 mm. Similarly, the length of the sample tube 20 can also be determined in this way.
[0034] In one embodiment, as shown in Figure 2 The open end of the sample tube 20 is provided with a strip-shaped hole 22 extending towards the closed end; the side surface of the clamping head 30 is provided with a protruding block 34; and the protruding block 34 is used for moving in the strip-shaped hole 22. By arranging the protruding block 34 and the strip-shaped hole 22, the clamping head 30 can be limited, so as to prevent the fixed section 32 from shaking and rotating in the sample tube 20, which can make the fitting surface 33 perpendicular to the axis of the steel sample 10, and make the fitting surface 33 and the cross section of the steel sample 10 fit more closely, so as to obtain more accurate measurement results.
[0035] More preferably, the number of strip-shaped holes 22 and protruding blocks 34 can be multiple. As shown in Figure 3 and Figure 4 Most preferably, two strip-shaped holes 22 and two protruding blocks 34 are arranged.
[0036] It should be noted that the front section of the clamping head 30 is the fixed section 32, and the rear section is the handheld section 31; the outer peripheral surface shape of the fixed section 32 is the same as the inner peripheral surface shape of the sample tube 20. The diameter of the handheld section 31 is smaller than the diameter of the fixed section 32, which can facilitate the measurement personnel to hold, and a variable diameter structure is arranged between the handheld section 31 and the fixed section 32.
[0037] As a specific implementation, the pointer 35 is arranged on the convex block 34. The pointer 35 can be a mark coated or printed on the surface of the convex block 34, so that no additional structure is needed, and the manufacturing cost and difficulty are reduced.
[0038] As another specific implementation, as shown in Figure 5 the pointer 35 is arranged on the fixed section 32; the pointer 35 is a strip, and the pointer 35 has a gap with the fixed section 32. The rear end of the pointer 35 is connected to the rear of the fixed section 32, and the gap therebetween can be used for the sample tube 20 to pass through. Thus, the corresponding position of the pointer 35 to the abutting surface 33 is marked, and the size information of the steel sample 10 can be directly observed.
