[0029] like Figs. 1 to 3 As shown, a positioning mechanism for a portable hardness tester includes an installation module 1 and a positioning module 2 disposed on the installation module 1; the installation module 1 is used to install and fix it onto the surface to be tested; the positioning module 2 is provided with a positioning groove 21, which is used to position and install a hardness testing device 3 so that the testing head of the hardness testing device 3 is perpendicular to the surface to be tested.

[0030] As an example, this application embodiment provides a positioning mechanism for a portable hardness tester, including an installation module 1 and a positioning module 2, with the positioning module 2 mounted on the installation module 1. The installation module 1 is used to mount and fix the device onto the surface to be tested, ensuring the stability of the entire positioning mechanism. The positioning module 2 is provided with a positioning groove 21, which is specifically designed to match the outer contour of the portable hardness tester for precise positioning of the hardness testing device 3. Through precise geometric and angle design, the positioning module 2 ensures that when the hardness testing device 3 is installed in the positioning groove 21, the testing head on the hardness testing device 3 is perpendicular to the surface being tested, achieving rapid positioning and thus improving the accuracy and efficiency of testing. After testing, the hardness testing device 3 can be easily removed from the positioning groove 21. The advantages of the portable hardness tester positioning mechanism of this embodiment are: its ingenious structural design, ease of operation, and accurate positioning, significantly improving the accuracy and efficiency of hardness testing.

[0031] In one embodiment, see Fig. 2 and Fig. 3 The installation 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, and 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, to facilitate the use of a portable hardness tester to test bends or elbows with a certain angle by testing personnel, the installation module 1 in this embodiment is designed as a split structure, including 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, allowing them to rotate relative to the positioning module 2. When encountering bends or elbows with a curvature ≤10°, the first base 11 and the second base 12 are first adjusted to a certain angle by rotating them, allowing them to be installed at both ends of the bend or elbow. Then, the locking member 13 locks the first base 11 and the second base 12 to the positioning module 2, securing their relative positions and ensuring the stability of the installation module 1. Finally, the hardness testing device 3 is installed into the positioning slot 21 of the positioning module 2 to achieve accurate testing of the bend or elbow.

[0033] In one embodiment, see Fig. 2 and Fig. 3 Both the first base 11 and the second base 12 are provided with cylindrical connecting columns 14. The two ends of the positioning module 2 are provided with connecting holes 22 that match the connecting columns. The connecting columns pass through the connecting holes 22 and rotate relative to the positioning module 2.

[0034] As an example, to enable both the first base 11 and the second base 12 to rotate relative to the positioning module 2, allowing for Brinell hardness testing of bends or elbows with a curvature ≤10°, this embodiment provides cylindrical connecting posts 14 on both the first base 11 and the second base 12, while the positioning module 2 has connecting holes 22 at both ends that match the connecting posts. When assembling the mounting module 1 and the positioning module 2, the connecting posts 14 are inserted into the connecting holes 22, allowing the first base 11 and the second base 12 to rotate and adjust relative to the positioning module 2. Before testing, the first base 11 and the second base 12 are rotated to adjust to a suitable angle, and then the locking member 13 is used to lock and fix the first base 11 and the second base 12 to the positioning module 2, thereby locking the relative position between the first base 11 and the second base 12 and the positioning module 2, ensuring that the mounting module 1 can be stably installed and fixed on the bend or elbow for accurate testing. Meanwhile, since the first base 11 and the second base 12 are respectively connected to 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 connection process, and the locking height of the locking member 13 can be adjusted in conjunction with the adjustment, so that the height of the two sides of the positioning module 2 can be adjusted with a misalignment of ≤5mm. When the measured position is at the weld joint of the pipe with a change in diameter, that is, when there is a height deviation on both sides of the weld, this design can adjust the height difference on both sides of the positioning module 2, so that the detection head of the hardness testing device 3 is perpendicular to the measured plane, and can be tested at the position with a change in diameter or 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 the weld joint with a change in diameter or a misalignment of ≤5mm and the bend or elbow of ≤10°.

[0035] In one embodiment, see Fig. 2 and Fig. 3 The end of the connecting column 14 is provided with an external thread, and the locking member 13 is a nut. The locking member 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, to facilitate the locking operation, this embodiment has an external thread at the end of the connecting column 14, and the locking member 13 adopts a nut structure. The locking member 13 is connected to the end of the connecting column 14 through a threaded connection. Before testing, by loosening the nut of the locking member 13, the first base 11 and the second base 12 can be quickly and easily 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, the second base 12 and the positioning module 2 can be quickly locked, ensuring the stability of the positioning mechanism and thus achieving accurate testing.

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

[0038] As an example, to improve the locking effect of the locking member 13, the surface of the positioning module 2 at the connection hole 22 is designed as a concave spherical surface, while the bottom of the locking member 13 is designed as a convex spherical surface that matches the concave spherical surface, with 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, improving the stability of locking, but also compensates for minor deviations caused by manufacturing errors or improper installation to a certain extent, ensuring the balance and stability of the positioning module 2 and improving the accuracy of detection.

[0039] In one embodiment, see Fig. 3 Both the bottom of the first base 11 and the bottom of the second base 12 are provided with arc-shaped grooves 101 for fitting with the arc-shaped surface to be tested.

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

[0041] In one embodiment, see Fig. 1 to 3 Both the first base 11 and the second base 12 are 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 ease of installation of the mounting module 1 on magnetic materials, both the first base 11 and the second base 12 in this embodiment are designed as magnetic fixing structures. This design simplifies the installation and fixing process, allowing the positioning mechanism to easily adhere to the surface of the ferromagnetic material being tested without the need for additional fixing devices.

[0043] In one embodiment, see Figs. 1 to 3 Both the first base 11 and the second base 12 are equipped with magnetic switches 102.

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

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

[0046] As an example, this embodiment adopts a split structure in the design of the positioning groove 21. The positioning groove 21 is divided into an upper groove 211 and a lower groove 212. The upper groove 211 matches and connects with the upper end of the hardness testing device 3, and the lower groove 212 matches and connects with the lower end of the hardness testing device 3. This dual-groove design can better support and position the hardness testing device 3, ensuring the stable assembly and positioning of the hardness testing device 3, preventing it from shaking or tilting during the testing process, and improving the testing accuracy.

[0047] In one embodiment, see Fig. 2 and Fig. 3 The positioning module 2 is equipped with a handle 23.

[0048] As an example, to facilitate user carrying and moving of this positioning mechanism, this embodiment also provides a rotating handle 23 on the positioning module 2. The user can easily lift the positioning mechanism and move it to the desired position using the handle 23. The rotating handle 23 has a straddle structure, with both ends rotatably connected to the positioning module 2. A flat pad is also placed between the handle 23 and the positioning module 2 to reduce friction.

[0049] It should also be noted that, without conflict, the embodiments of this utility model and the features therein can be combined with each other to obtain new embodiments.
