[0029] like Figures 1 to 3 As shown, a positioning mechanism of a portable hardness tester includes a mounting module 1 and a positioning module 2 arranged on the mounting module 1; the mounting module 1 is used to be installed and fixed to the surface to be tested; the positioning module 2 is provided with a positioning groove 21, and the positioning groove 21 is used to position and install a hardness testing device 3 so that the detection head of the hardness testing device 3 is perpendicular to the surface to be tested.

[0030] As an example, the embodiment of the present application provides a positioning mechanism of a portable hardness tester, including a mounting module 1 and a positioning module 2, wherein the positioning module 2 is mounted on the mounting module 1; wherein the mounting module 1 is used to be mounted and fixed to the surface to be tested to ensure the stability of the entire positioning mechanism; the positioning module 2 is provided with a positioning groove 21, which is specially designed to match the outer contour structure of the portable hardness tester, and is used to accurately position and install the hardness detection device 3; the positioning module 2 ensures that when the hardness detection device 3 is installed in the positioning groove 21 through precise geometric structure design and angle design, the detection head on the hardness detection device 3 can be perpendicular to the surface to be detected, thereby achieving rapid positioning, thereby improving the accuracy and efficiency of the detection; after the test is completed, the hardness detection device 3 can be directly and conveniently taken out of the positioning groove 21. The advantages of the portable hardness tester positioning mechanism of this embodiment are: its structural design is ingenious, it has the advantages of simple operation and accurate positioning, and can significantly improve the accuracy and efficiency of hardness detection.

[0031] In one embodiment, see Figure 2 and Figure 3 The mounting module 1 includes a first base 11, a second base 12 and a locking member 13. The first base 11 and the second base 12 are rotatably connected to the positioning module 2 respectively. The locking member 13 is used to lock the relative position between the first base 11 and the second base 12 and the positioning module 2.

[0032] As an example, in order to facilitate the inspection personnel to use the portable hardness tester to inspect the curved pipe or elbow with a certain angle, the installation module 1 of this embodiment is designed as a split structure, including a first base 11, a second base 12 and a locking member 13. Among them, the first base 11 and the second base 12 are respectively connected to the positioning module 2, so that the first base 11 and the second base 12 can rotate relative to the positioning module 2; when encountering a curved pipe or elbow with a curvature of ≤10°, first adjust the first base 11 and the second base 12 to a certain angle by rotating them, so that the first base 11 and the second base 12 can be installed at both ends of the curved pipe or elbow respectively; then, the first base 11 and the second base 12 are respectively locked and fixed with the positioning module 2 by the locking member 13, and the relative position between the first base 11 and the second base 12 and the positioning module 2 is locked to ensure the stability of the installation module 1; finally, the hardness detection device 3 is installed in the positioning slot 21 of the positioning module 2 to achieve accurate detection of the curved pipe or elbow.

[0033] In one embodiment, see Figure 2 and Figure 3 The first base 11 and the second base 12 are both provided with cylindrical connecting columns 14. Both ends of the positioning module 2 are provided with connecting holes 22 matching the connecting columns. The connecting columns are inserted into the connecting holes 22 and rotate relative to the positioning module 2.

[0034] As an example, in order to enable the first base 11 and the second base 12 to rotate relative to the positioning module 2, so as to realize the Brinell hardness test of the curved pipe or elbow with a curvature of ≤10° using the tooling; in this embodiment, cylindrical connecting columns 14 are provided on the first base 11 and the second base 12, and connecting holes 22 matching the connecting columns are provided at both ends of the positioning module 2; when the installation module 1 is assembled with the positioning module 2, the connecting columns 14 are inserted into the connecting holes 22, so that the first base 11 and the second base 12 can be rotated and adjusted relative to the positioning module 2. Before the test, the first base 11 and the second base 12 are rotated to adjust to a suitable angle, and then the first base 11 and the second base 12 are locked and fixed with the positioning module 2 by the locking member 13 to lock the relative position between the first base 11 and the second base 12 and the positioning module 2, so as to ensure that the installation module 1 can be stably installed and fixed on the curved pipe or elbow to achieve accurate detection. At the same time, since the first base 11 and the second base 12 are docked with the connection hole 22 of the positioning module 2 through the cylindrical connecting column 14, the height of the positioning module 2 on both sides of the first base 11 and the second base 12 can be adjusted up and down during the docking process, and the locking height of the locking member 13 can be adjusted to achieve a misalignment adjustment of ≤5mm in height on both sides of the positioning module 2; when the measured position is at the position of the large and small pipe diameter reducing welding joint, that is, when there is a deviation in the height on both sides of the weld, the design can adjust the height difference on both sides of the positioning module 2, so that the detection head of the hardness detection equipment 3 is in a vertical state with the measured plane, and can be tested at a position where the diameter is changed or there is a misalignment of ≤5mm, so as to achieve accurate detection. Therefore, the connection structure between the first base 11 and the second base 12 and the positioning module 2 can improve the applicability of the positioning mechanism of this embodiment, and can be flexibly applied to welds with diameter changes or misalignments of ≤5mm and bends or elbows of ≤10°.

[0035] In one embodiment, see Figure 2 and Figure 3 The end of the connecting column 14 is provided with an external thread, the locking piece 13 is set as a nut, and the locking piece 13 is threadedly connected to the end of the connecting column 14 to lock the relative position between the first base 11 and the second base 12 and the positioning module 2.

[0036] As an example, in order to facilitate the locking operation, the present embodiment is provided with an external thread at the end of the connecting column 14, and the locking member 13 adopts a nut structure, and the locking member 13 is connected to the end of the connecting column 14 by a threaded connection. Before the test, by loosening the nut of the locking member 13, the first base 11 and the second base 12 can be quickly and conveniently rotated to adjust the angle; after the angle adjustment is completed, by tightening the nut of the locking member 13, the relative position between the first base 11 and the second base 12 and the positioning module 2 can be quickly locked to ensure the stability of the positioning mechanism, thereby achieving accurate detection.

[0037] In one embodiment, see Figure 3 The connection hole 22 of the positioning module 2 is set as a concave spherical surface, the bottom of the locking member 13 is set as a convex spherical surface matching the concave spherical surface, and the bottom of the locking member 13 and the positioning module 2 are in spherical contact.

[0038] As an example, in order to improve the locking effect of the locking member 13, the surface of the positioning module 2 at the connection hole 22 of this embodiment is designed as a concave spherical surface, and the bottom of the locking member 13 is designed as a convex spherical surface matching the concave spherical surface, and there is spherical contact between the bottom of the locking member 13 and the positioning module 2. This design not only increases the contact area between the locking member 13 and the positioning module 2 and improves the locking stability, but also can compensate for minor deviations caused by manufacturing errors or improper installation to a certain extent, ensure the balance and stability of the positioning module 2, and improve the accuracy of detection.

[0039] In one embodiment, see Figure 3 The bottom of the first base 11 and the bottom of the second base 12 are both provided with arc-shaped grooves 101 for fitting with the arc-shaped detected surface.

[0040] As an example, in order to adapt to the different shapes of the detected surfaces, this embodiment has an arc-shaped groove 101 at the bottom center of the first base 11 and the second base 12. The arc-shaped groove 101 can fit tightly with the arc surface on the detected surface (such as a circular tube), thereby ensuring the stability of the installation module 1 and improving the detection accuracy.

[0041] In one embodiment, see Figures 1 to 3 The first base 11 and the second base 12 are both magnetic fixing structures.

[0042] As an example, since magnetic steel products are also widely used in the production of large equipment, in order to improve the installation convenience of the installation module 1 on magnetic material products, the first base 11 and the second base 12 of this embodiment are designed as magnetic fixing structures. This design simplifies the installation and fixing process, so that the positioning mechanism can be easily adsorbed on the detected surface of the ferromagnetic material without the need for additional fixing devices.

[0043] In one embodiment, see Figures 1 to 3 The first base 11 and the second base 12 are both provided with a magnetic switch 102 .

[0044] As an example, in order to conveniently control the opening and closing of the magnetic force, a magnetic switch 102 is also provided on the first base 11 and the second base 12 of this embodiment. The addition of the magnetic switch 102 allows the user to easily control the opening and closing of the magnetic attraction function of the first base 11 and the second base 12, thereby improving the convenience and flexibility of installation and disassembly.

[0045] In one embodiment, see Figure 3 The positioning groove 21 includes an upper groove 211 connected to the upper end of the hardness testing device 3 and a lower groove 212 connected to the lower end of the hardness testing device 3.

[0046] As an example, the present embodiment adopts a split structure in the design of the positioning groove 21, and the positioning groove 21 is divided into an upper groove 211 and a lower groove 212, wherein the upper groove 211 matches and docks with the upper end of the hardness testing device 3, and the lower groove 212 matches and docks with the lower end of the hardness testing device 3. Such a double groove design can better support and position the hardness testing device 3, ensure the stable assembly and positioning of the hardness testing device 3, prevent it from shaking or tilting during the detection process, and improve the detection accuracy.

[0047] In one embodiment, see Figure 2 and Figure 3 A handle 23 is provided on the positioning module 2.

[0048] As an example, in order to facilitate the user to carry and move the positioning mechanism, the present embodiment further provides a rotating handle 23 on the positioning module 2, and the user can easily lift and move the positioning mechanism to a desired position through the handle 23. The rotating handle 23 is a straddle structure, and its two ends are respectively rotatably connected to the positioning module 2, and a flat pad is also provided between the handle 23 and the positioning module 2 to reduce certain friction.
