Description

Technical Field

[0001] This utility model relates to the technical field of rapid hardness testers, specifically a multifunctional rapid hardness tester for materials. Background Technology

[0002] A rapid hardness tester is a specialized instrument used to measure the surface hardness of materials. Hardness testers are divided into benchtop hardness testers and portable hardness testers. Benchtop hardness testers are mainly used in laboratories and have the advantage of high accuracy, while portable hardness testers are suitable for installed machinery or permanently assembled parts and are easy to carry. Portable hardness testers integrate Leeb, Brinell, and Rockwell hardness testers, enabling free conversion between seven different hardness values. This eliminates the drawbacks of traditional hardness testers that required manual hardness chart lookup, achieving true intelligence and portability.

[0003] When using a rapid hardness tester, the material needs to be placed on the test platform, and then the probe is activated to contact the material to obtain the material hardness data. However, considering that the probe needs to apply pressure to the material during the measurement process, the material is prone to warping, which affects the accuracy of the test. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional rapid material hardness tester to solve the problems mentioned in the background art.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a pressing mechanism, allows the material to be placed on the test table when testing is required. Then, the rotating block is turned, which drives the threaded rod to rotate inside the threaded hole. As the threaded rod rotates, it drives the pressure plate and rubber pad to move downwards synchronously. Then, the pressure plate presses on the material. The above steps are repeated so that multiple pressure plates press evenly on the material, which can effectively prevent the material from lifting up during subsequent testing, improve the accuracy of testing, and prevent the material from breaking due to uneven force. It achieves multiple functions such as preventing the material from lifting up, improving the accuracy of testing, and preventing the material from breaking. 2. This utility model, by setting an adjustment mechanism, can move the push block upward, which in turn drives the linkage block, connecting block, and positioning rod upward, causing the positioning rod to leave the interior of the positioning hole. Then, under the constraint of the T-shaped block, the position of the support block moves along the trajectory of the T-shaped slide groove, while simultaneously driving the pressing mechanism to move, so that the pressure plate in the pressing mechanism is just at the top of the material. After releasing the push block, the elastic force generated by the spring will push the linkage block, connecting block, and positioning rod downward, causing the positioning rod to enter the interior of the corresponding positioning hole. At this time, the pressing mechanism can control the pressure plate to accurately press on the material, thereby improving the stability during material testing. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 - Figure 5 As shown, Example 1: A multifunctional material hardness rapid tester includes a tester body 1, a probe 2 and a test platform 3. The probe 2 is driven to the bottom of the inner wall of the tester body 1. The test platform 3 is fixedly installed on the top of the inner wall of the tester body 1. Several fixing blocks 4 are provided on the top of the test platform 3. Support blocks 5 are fixedly connected to the top of the fixing blocks 4. A pressing mechanism is provided on the top of the support blocks 5. The adjustment mechanism is located inside the support block 5 and can adjust the pressing position of the pressing mechanism according to the shape of the material being tested.

[0018] The pressing mechanism includes a screwing block 6 located on the top of the support block 5. The surface of the screwing block 6 is provided with an anti-slip groove 7. A threaded rod 8 is fixedly connected to the bottom of the screwing block 6. A pressure plate 9 is fixedly connected to the bottom of the threaded rod 8. A threaded hole 10 that mates with the threaded rod 8 is provided on the top of the support block 5.

[0019] In this embodiment, considering that the probe 2 needs to apply pressure to the material during the measurement process, the material is prone to warping, which affects the accuracy of the test. Therefore, by setting up a pressing mechanism, when the material needs to be tested, the material is placed on the test stage 3, and then the rotating block 6 is rotated, which drives the threaded rod 8 to rotate inside the threaded hole 10. While the threaded rod 8 is rotating, it will drive the pressure plate 9 and the rubber pad 21 to move downwards synchronously. Then the pressure plate 9 will press on the material. The above steps are repeated so that multiple pressure plates 9 press evenly on the material, which can effectively prevent the material from warping during subsequent testing, improve the accuracy of the test, and at the same time, the multiple pressure plates 9 pressing evenly on the material can also prevent the material from breaking due to uneven force. This achieves multiple functions such as preventing the material from warping, improving the accuracy of the test, and preventing the material from breaking.

[0020] A rubber pad 21 is fixedly connected to the bottom of the pressure plate 9. The thickness of the rubber pad 21 is 2mm.

[0021] In this embodiment, by setting a rubber pad 21, the contact area between the pressure plate 9 and the material can be increased when the pressure plate 9 presses on the material, thereby improving the pressing effect and also playing a buffering role.

[0022] Example 2: Based on Embodiment 1, the pressing mechanism in this embodiment can prevent the material from warping during the testing process by pressing the pressure plate 9 onto the material. However, considering that the shape of the material may vary, if the pressure plate 9 cannot be pressed stably onto the material surface, it will also affect the material warping during the testing process. In this application, the adjustment mechanism includes a transmission groove 11 opened inside the fixed block 4. A linkage block 12 is provided inside the transmission groove 11. Connecting blocks 13 are fixedly connected to both sides of the linkage block 12. A positioning rod 14 is fixedly connected to the bottom of the connecting block 13. A positioning hole 15 for use with the positioning rod 14 is opened on the top of the test platform 3.

[0023] In this embodiment, by setting an adjustment mechanism, the push block 17 can be moved upward, which will drive the linkage block 12, connecting block 13 and positioning rod 14 to move upward, so that the positioning rod 14 leaves the interior of the positioning hole 15. Then, under the restriction of the T-shaped block 19, the position of the support block 5 moves along the trajectory of the T-shaped slide groove 20, while driving the pressing mechanism to move, so that the pressure plate 9 in the pressing mechanism is just at the top of the material. Then, the push block 17 is released, and the elastic force generated by the spring 16 will push the linkage block 12, connecting block 13 and positioning rod 14 downward, so that the positioning rod 14 enters the interior of the corresponding positioning hole 15. At this time, the pressing mechanism can control the pressure plate 9 to accurately press on the material, thereby improving the stability during material testing.

[0024] A spring 16 is fixedly connected to the top of the linkage block 12, and the top of the spring 16 is fixedly connected to the inner wall of the transmission groove 11.

[0025] In this embodiment, by setting a spring 16, when the user releases the push block 17, the elastic force generated by the spring 16 will drive the push linkage block 12 and other structures to move downward, thus achieving the function of resetting.

[0026] A push block 17 is fixedly connected to one side of the linkage block 12, and a push groove 18 that works with the push block 17 is provided on one side of the fixed block 4.

[0027] In this embodiment, by setting the push block 17 and the push groove 18, it is convenient for the user to drive the linkage block 12 to move, and at the same time, it can also limit the movement trajectory of the linkage block 12 and other structures, thereby improving the stability during its movement.

[0028] The bottom of the fixed block 4 is fixedly connected to a T-shaped block 19, and the top of the test platform 3 is provided with a T-shaped groove 20 that works in conjunction with the T-shaped block 19.

[0029] In this embodiment, by setting T-shaped block 19 and T-shaped slide 20, a movement trajectory can be provided for the mechanism such as fixed block 4, so that it can only move along the trajectory of T-shaped slide 20 under the restriction of T-shaped block 19, and at the same time, the stability of its movement is improved.

[0030] The number of positioning holes 15 is several, and they are evenly distributed on the top of the test platform 3.

[0031] In this embodiment, by setting multiple positioning holes 15, the positioning rod 14 can be inserted into the corresponding positioning hole 15 after the positions of the fixing block 4 and the support block 5 are adjusted, thereby achieving rapid fixing of the fixing block 4 and the support block 5.

[0032] Working principle: When materials need to be tested, the materials are placed on the test bench 3. Then, the screw block 6 is rotated, which drives the threaded rod 8 to rotate inside the threaded hole 10. As the threaded rod 8 rotates, it drives the pressure plate 9 and the rubber pad 21 to move downwards simultaneously. Then the pressure plate 9 presses on the material. The above steps are repeated so that multiple pressure plates 9 press evenly on the material, which can effectively prevent the material from lifting up during subsequent testing and improve the accuracy of testing. The push block 17 can also be moved upwards, which will cause the linkage block 12, connecting block 13 and positioning rod 14 to move upwards, so that the positioning rod 14 leaves the interior of the positioning hole 15. Then, under the constraint of the T-shaped block 19, the support block 5 moves along the trajectory of the T-shaped slide 20, while driving the pressing mechanism to move, so that the pressure plate 9 in the pressing mechanism is just at the top of the material. Then, the push block 17 is released, and the elastic force generated by the spring 16 will push the linkage block 12, connecting block 13 and positioning rod 14 downwards, so that the positioning rod 14 enters the interior of the corresponding positioning hole 15. At this time, the pressing mechanism can control the pressure plate 9 to press accurately on the material, thereby improving the stability during material testing.
