[0032] refer to Figure 1The verification device includes a first verification unit 1, a second verification unit 2 and a third verification unit 3 connected to each other; the first verification unit 1 is used to verify the side length of the test piece 4 to determine whether the side length of the test piece 4 is between a first preset length and a second preset length; the second verification unit 2 is used to verify the flatness of the side surface of the test piece 4 to determine whether the flatness of the side surface of the test piece 4 is between the first preset flatness and the second preset flatness; the third verification unit 3 is used to verify the angle formed by two adjacent side surfaces of the test piece 4 to determine whether the angle formed by two adjacent side surfaces of the test piece 4 is between the first preset angle and the second preset angle.

[0033] Specifically, the first preset length is equal to the nominal side length of the specimen 4 - 1 mm, and the nominal side length refers to the standard side length of the specimen 4, which can be 50 mm, 100 mm, or 150 mm. The second preset length is equal to the nominal side length of the specimen 4 + 1 mm, and the nominal side length refers to the standard side length of the specimen 4, which can be 50 mm, 100 mm, or 150 mm. This is set because the standard stipulates that the side length dimension tolerance of the specimen 4 shall not exceed 1 mm.

[0034] Specifically, according to the standard setting, the first preset flatness is 0, and the second preset flatness is 0.0005d, where d is specifically the nominal side length of the test piece 4 .

[0035] Specifically, according to the standard setting, the first preset angle value is 89.5 degrees, and the second preset angle value is 90.5 degrees.

[0036] refer to Figure 1 The first verification unit 1 includes a first body 11, a first clamping arm 12, a second clamping arm 13 and a boss 14. The first clamping arm 12 and the second clamping arm 13 are arranged side by side on the first body 11, and a first receiving groove 15 is provided between the first clamping arm 12 and the second clamping arm 13. The boss 14 is provided on the side of the first clamping arm 12 facing the second clamping arm 13. A second receiving groove 16 is provided between the boss 14 and the second clamping arm 13. The second receiving groove 16 is connected to the first receiving groove 15. The second receiving groove 16 is closer to the first body 11 than the first receiving groove 15. The size of the first receiving groove 15 is equal to the second preset length, and the size of the second receiving groove 16 is equal to the first preset length. The first receiving groove 15 and the second receiving groove 16 are both used for placing the test piece 4 to determine whether the side length of the test piece 4 is between the first preset length and the second preset length.

[0037] The operating principle of the first verification unit 1 is: when the specimen 4 can enter the first receiving groove but cannot enter the second receiving groove, the side length of the specimen 4 is between the first preset length and the second preset length, which meets the standard requirements. In other cases, the side length of the specimen 4 is not between the first preset length and the second preset length, which does not meet the standard requirements.

[0038] Specifically, the first clamp arm 12 and the second clamp arm 13 are vertically arranged on the first body 11. The first body 11, the first clamp arm 12, the second clamp arm 13 and the boss 14 are rectangular in shape, which is convenient for the machine to produce the first body 11, the first clamp arm 12, the second clamp arm 13 and the boss 14.

[0039] refer to Figure 1 The first clamping arm 12 can move relative to the first body 11 toward or away from the second clamping arm 13 to adjust the size of the first receiving groove 15 and the second receiving groove 16. This arrangement facilitates the inspection of test pieces 4 with different side lengths.

[0040] refer to Figure 1 A scale line 17 is provided on one side of the first body 11 facing the second receiving groove 16, and the scale line 17 is used to indicate the size of the second receiving groove 16. Specifically, the accuracy and range of the scale line 17 can be set according to the test pieces 4 of different sizes.

[0041] refer to Figure 1 The boss 14 has a first reference surface 141, the width of which is equal to the difference between the second preset length and the first preset length, and the first reference surface 141 is used to abut against the side of the test piece 4 to keep the test piece 4 whose side length is between the first preset length and the second preset length in the first containing groove 15. Specifically, the width of the first reference surface 141 is 2 mm.

[0042] refer to Figure 1 The first checking unit 1 further includes a fastener 18, which is disposed on the first body 11 and is used to fix the first clamping arm 12 on the first body 11. Specifically, the fastener 18 may be, but is not limited to, a fastening screw.

[0043] refer to Figure 1 The first body 11 is provided with a slide groove 19, and the fastener 18 can be inserted into the slide groove 19 and matched with the first clamping arm 12, and the fastener 18 can move along the slide groove 19 to adjust and lock the connection position between the first clamping arm 12 and the first body 11. Specifically, when the first clamping arm 12 needs to be driven to move along the first body 11, the fastener 18 is loosened, and when the first clamping arm 12 needs to be moved to a desired position, the fastener 18 is locked to fix the first clamping arm 12 on the first body 11, thereby achieving the fixation of the first clamping arm 12.

[0044] refer to Figure 2 and Figure 3The second checking unit 2 includes a second body 21 and a feeler gauge 22. The second body 21 is connected to the first checking unit 1. The second body 21 has a second reference surface 211. The second reference surface 211 is a plane. The second reference surface 211 is used to abut the side of the test piece 4. The feeler gauge 22 includes a first plane 221 and a second plane 222 that are arranged opposite to each other in the thickness direction. There are multiple feeler gauges 22. The thicknesses of the multiple feeler gauges 22 are different from each other, and the thickness of each feeler gauge 22 is between the first preset flatness and the second preset flatness. If the second reference surface 211 directly abuts against the side surface of the test piece 4 without a gap, it can be determined that the flatness of the side surface of the test piece 4 is between the first preset flatness and the second preset flatness; if the second reference surface 211 and the side surface of the test piece 4 abut against each other with a gap, when one of the feeler gauges 22 can be inserted into the gap, and the first plane 221 and the second plane 222 of the inserted feeler gauge 22 abut against the second reference surface and the side surface of the test piece 4 respectively, it can be determined that the flatness of the side surface of the test piece 4 is between the first preset flatness and the second preset flatness.

[0045] The operating principle of the second verification unit 2 is as follows: the second reference surface 211 is close to the side surface of the specimen 4, and the feeler gauge 22 is inserted into the gap between the second reference surface 211 and the side surface of the specimen 4 after they are butted against each other, and the gap is measured with the feeler gauge 22, and then the second body 21 is rotated. At the same time, the gap is measured with the feeler gauge 22 until the feeler gauge 22 measures the maximum gap between the second reference surface 211 and the side surface of the specimen 4 after they are butted against each other, and the maximum gap measured by the feeler gauge 22 is used as the flatness of the side surface of the specimen 4. If the flatness of the side surface of the specimen 4 is between the first preset flatness and the second preset flatness, then the flatness of the side surface of the specimen meets the standard requirements.

[0046] Specifically, the second body 21 is shared with the first body 11 in order to save materials and production costs.

[0047] Specifically, the feeler gauge 22 is a measuring tool, mainly used for measuring gap spacing, and is a gauge composed of a group of thin steel sheets with different thickness differences.

[0049] Specifically, the connection between the first inclined surface 321 and the second inclined surface 322 has an intersection line 323, and the specimen 4 can be placed in the third accommodating groove 33. After one of the two adjacent side surfaces of the specimen 4 is tightly attached to the third clamping arm 31, as long as the other side surface of the specimen 4 is in contact with the intersection line 323, it can be determined that the angle between the two adjacent side surfaces of the specimen 4 is between the first preset angle value and the second preset angle value, and the angle between the two adjacent side surfaces of the specimen 4 meets the standard requirements.

[0050] Specifically, the third clamping arm 31 is shared with the second clamping arm 13 in order to save materials and production costs. The fourth clamping arm 32 is disposed in the extension direction of the first body 11 .
