The verification tool is described in detail below.
The utility model provides a riveting nut height check tool has set up a reference surface and two check faces in order to detect whether can detect the height that riveting nut highly in the within range of setting for, and two check faces are first check face and second check face respectively, and reference surface, first check face and second check face are parallel to each other. The vertical distance from the first checking surface to the reference surface is a first set distance, the vertical distance from the second checking surface to the reference surface is a second set distance, and the first set distance is the highest height of the riveted nut to be checked; the second set distance is the lowest height of the verified riveting nut, and the difference value of the first set distance and the second set distance is the height value which needs to be met by the verified riveting nut. Whether the height of the riveting nut meets the design requirement or not is detected through the checking surface. The design requirements for different riveting nuts are different, but the adopted verification tools are similar in structure and only differ in size, so that only the structure of the verification tool is explained here, and the first set distance and the second set distance which are different in size can be designed according to the riveting nuts which are different in verification.
The structure of the verification tool will be described in detail below with reference to a specific example of the verification tool, and fig. 1 to 3 are also referred to, wherein fig. 1, 2 and 3 respectively show a side view, a top view and a bottom view of the clinch nut height verification tool. As shown in fig. 1, the verification tool includes a verification body, and the verification body has a plurality of parallel faces, which are the first verification face 12, the second verification face 22, and the reference face, respectively. The checking body is of a Z-shaped structure and comprises two horizontal parts, namely a first horizontal part 1 and a second horizontal part 2, and a connecting part for connecting the first horizontal part 1 and the second horizontal part 2, wherein the thickness of the first horizontal part 1 is smaller than that of the second horizontal part 2. When the connection part is specifically provided, the connection part is perpendicular to the first horizontal part 1 and the second horizontal part 2, respectively.
In the configuration shown in fig. 1, the number of the reference surfaces is two, and the reference surfaces are the first reference surface 11 and the second reference surface 21, respectively, and the arrangement of the verification surface and the reference surfaces on the verification body will be described below with reference to fig. 1 to 3. The first horizontal portion 1 has two parallel surfaces, one of the two parallel surfaces faces the second horizontal portion 2, and the other faces away from the second horizontal portion 2, wherein one face facing the second horizontal portion 2 is a first calibration face 12, and one face facing away from the second horizontal portion 2 is a first reference face 11. The second horizontal portions 2 respectively have two parallel surfaces, one of the two parallel surfaces faces the first horizontal portion 1, and the other faces away from the first horizontal portion 1, wherein one face facing the first horizontal portion 1 is a second verification face 22, and one face facing away from the first horizontal portion 1 is a second reference face 21. In use, the first verification surface 12 is engaged with the second reference surface 21 with a vertical distance therebetween being a first set distance d, which is the highest distance of the riveted nut being verified. The second checking surface 22 is matched with the first reference surface 11, and the vertical distance between the two is a second set distance h which is the lowest distance of the riveted nut to be checked.
Referring to fig. 4 together, fig. 4 shows a using state diagram of the verifying tool, wherein fig. 4 shows that the first datum plane 11 is adopted to be attached to the arrangement plane of the verified rivet nut 10, so as to ensure that the second verifying plane 22 is parallel to the top plane of the verified rivet nut 10, and then the verifying tool is slid, so that the second verifying plane 22 sweeps across the top plane of the verified rivet nut 10, if the top plane of the rivet nut 10 passes through the lower part of the second verifying plane 22, the height of the rivet nut 10 is lower than a second set distance h, namely, the minimum height which the rivet nut 10 should reach is indicated, at this moment, the rivet nut 10 is judged to be unqualified, and if the top part of the rivet nut 10 should not pass through the second verifying plane 22, at this moment, the height of the rivet nut 10 is judged to reach the minimum height which the rivet nut should reach. And turning over the checking tool, attaching the second reference surface 21 to the placing surface of the riveting nut 10, repeating the above actions, judging that the height of the riveting nut 10 does not exceed the highest height when the riveting nut 10 can pass through the lower part of the first checking surface 12, and judging that the riveting nut 10 is qualified, and judging that the height of the riveting nut 10 is greater than the required highest height if the top surface of the riveting nut 10 cannot pass through the lower part of the first checking surface 12, and judging that the riveting nut 10 is unqualified.
Through the structure, the first checking surface 12 and the second checking surface 22 are located on two sides of the vertical portion, so that the whole structure is compact, and only the required checking surface and the reference surface are matched with the riveting nut respectively when the whole structure is detected, therefore, the riveting nut can be used in a smaller space, the checking process is simpler, the checking result can be directly obtained through the checking process, and errors caused by considered misjudgment are reduced.
In addition, in order to further facilitate the verification and avoid confusion between the first verification surface 12 and the second verification surface 22 during use, in the verification tool provided in this embodiment, a first indicating layer is disposed on the first reference surface 11, and a second indicating layer is disposed on the second reference surface 21.
