Description

Technical Field

[0001] The utility model relates to the technical field of measuring instruments, in particular to a high-precision hardness measuring instrument for metal materials. Background Art

[0002] Hardness testers use unique and precise designs in mechanics, optics, and light sources to make indentation imaging clearer and measurements more accurate. Currently, most commonly used hardness testers are for measuring the hardness of metals, so the existing high-precision hardness testers for metal materials have been continuously innovated and developed. Therefore, it can be seen that the current high-precision hardness testers for metal materials basically meet people's needs, but there are still some problems.

[0003] For example, the patent document with the announcement number CN218349971 U discloses a hardness measuring instrument, which is provided with "an instrument housing, a debris collection mechanism is provided at the lower end of the instrument housing, a rotating frame is provided on the outer wall of the instrument housing, a lifting frame is provided on the inner wall of the rotating frame, a measuring head is provided on the upper end of the lifting frame, shielding mechanisms are provided on the outer surfaces of both sides of the instrument housing, a control panel is provided on the front outer surface of the instrument housing, and the debris collection mechanism includes a moving wheel, a handle, a collection box, a buffer gasket and a connecting plug-in. This hardness measuring instrument can collect debris generated during measurement through the debris collection mechanism and the shielding mechanism, prevent the debris generated during measurement from falling to the ground and affecting people's cleaning, and reduce the labor intensity of the user."

[0004] However, when the above device is actually used, the collection box can be installed at the lower end of the instrument housing through a connecting plug-in, and the debris generated during the measurement can directly fall into the collection box for collection. Since the collection box is installed at the lower end of the instrument housing, the debris splashed during the measurement process is difficult to be effectively collected. In addition, since the connectivity between the debris collection mechanism and the instrument housing is poor, when the collection box is subjected to external force, it is easy to separate from the instrument housing, resulting in a decrease in the collection effect of the collection box, making it difficult to maintain the experimental environment. Therefore, a high-precision hardness tester for metal materials is urgently needed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a high-precision hardness tester for metal materials, so as to solve the problem in the background art that when the material is used, it is affected by strong force and splashes everywhere, thereby destroying the experimental environment.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution, which discloses a high-precision hardness tester for metal materials, comprising an instrument housing, an inner bottom wall of the instrument housing being provided with a rotating frame, and an inner wall of the rotating frame being connected to a lifting frame;

[0007] The first magnetic block is fixedly connected to both sides of the instrument housing, the outer surface of the first magnetic block is overlapped with a connecting frame, the inner wall of the connecting frame is fixedly installed with a second magnetic block, the front of the connecting frame is fixedly installed with a fixing frame, the inner wall of the instrument housing is fixedly installed with a guide frame, and support plates are fixedly installed on both sides of the guide frame.

[0008] Preferably, a support frame is provided on the top of the lifting frame, and a table is threadedly connected to the outer surface of the support frame.

[0009] Preferably, a pressure sensor is provided on the top of the support frame, and the pressure sensor is overlapped with the inner wall of the table top.

[0010] Preferably, the outer surface of the lifting frame is provided with a scale, and the inner top wall of the instrument housing is movably connected to a pressure head.

[0012] Preferably, a control panel is provided on the outer surface of the instrument housing, and an anti-slip pad is provided on the bottom of the instrument housing.

[0013] Preferably, the front surface of the guide frame is configured to be arc-shaped, and the guide frame overlaps the outer surface of the support frame.

[0014] Preferably, the fixing frame is provided in a U-shaped frame shape, and the fixing frame is overlapped on the outer surface of the guide frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The utility model clamps the connecting frame and the first magnetic block together, and the fixed frame moves to the supporting plate along with the connecting frame. At this time, the second magnetic block and the first magnetic block are tightly attached, and the attraction between the second magnetic block and the first magnetic block ensures the stability of the connecting frame, thereby stabilizing the fixed frame. At the same time, the supporting plate supports the fixed frame, further stabilizes the fixed frame, and ensures the use effect of the fixed frame. The fixed frame surrounds the pressure head and the table plate to collect debris, thereby achieving the purpose of maintaining the experimental environment. The guide frame is then used to guide the debris so that the debris can be effectively collected, and the measuring instrument can be shielded to prevent the problem of debris splashing when measuring metal materials from causing harm to the measuring personnel, which is beneficial to the safe use of the measuring instrument and improves the practicality of the device.

[0017] 2. The utility model sets the table into different shapes, and the contact surface between the metal material to be tested and the table has different inclination angles, which facilitates hardness measurement of metal materials at different angles. At the same time, the pressure sensor can determine the force applied to the metal material, and then use the scale to determine the vertical distance between the pressure head and the table, so as to achieve the purpose of accurately detecting the bearing capacity of metal materials under different states.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In the process of measuring the hardness of metal materials, the user drives the connecting frame 5 to move backward along the outer surface of the first magnetic block 4, and then the connecting frame 5 drives the second magnetic block 6 and the fixed frame 7 to move backward, so that the second magnetic block 6 and the first magnetic block 4 fit together with the fixed frame 7 and the guide frame 8, and there is a mutual attraction force between the second magnetic block 6 and the first magnetic block 4, thereby stabilizing the connecting frame 5, and then stabilizing the fixed frame 7, and then using the support plate 9 to support the fixed frame 7 to complete the installation of the fixed frame 7, and then the user drives the rotating frame 2 to rotate, and the lifting frame 3 moves up and down accordingly, and then the lifting frame 3 drives the supporting frame 10 to move up or down, and then The support frame 10 drives the table 11 to move upward or downward, thereby adjusting the vertical distance between the pressure head 14 and the table 11, and then the metal material to be tested is placed on the table 11, and the hardness tester is started through the control panel 16, so that the pressure head 14 hammers the metal material to be tested on the table 11 for testing. During this process, the fixed frame 7 surrounds the outer surface of the pressure head 14 and the table 11, which can shield the measuring instrument and play a protective role. At the same time, it can also collect the debris generated during the measurement, and guide the debris falling onto its surface through the guide frame 8, so that the collection effect of the fixed frame 7 is better.

[0028] Furthermore, a groove 15 is formed at the bottom of the fixed frame 7, and the support plate 9 overlaps the inner wall of the groove 15. The front of the guide frame 8 is set to be arc-shaped, and the guide frame 8 overlaps the outer surface of the support frame 10.

[0029] When the groove 15 contacts the support plate 9 , the support plate 9 can support the fixed frame 7 . The combination of the guide frame 8 and the support frame 10 ensures the collection effect of the debris.

[0030] See also Figure 1 、 Figure 2 and Figure 5 , an embodiment provided by the utility model:

[0031] A support frame 10 is provided on the top of the lifting frame 3. A table 11 is threadedly connected to the outer surface of the support frame 10. A pressure sensor 12 is provided on the top of the support frame 10, and the pressure sensor 12 is overlapped on the inner wall of the table 11. A scale 13 is provided on the outer surface of the lifting frame 3. A pressure head 14 is movably connected to the inner top wall of the instrument housing 1;

[0032] The pressure sensor 12 can be used to determine the magnitude of the pressure applied to the metal material, and the scale 13 can be used to determine the vertical distance between the pressure head 14 and the table 11. The table 11 has different shapes and the inclination angles of the metal material holding surface are different, so that the hardness of the metal material can be measured at different angles.

[0033] Furthermore, an anti-skid pad 17 is provided at the bottom of the instrument housing 1; the anti-skid pad 17 increases the friction between the contact surface of the instrument housing 1 and the laboratory table, thereby ensuring the stability of the instrument housing 1 and making the hardness measurement result of the metal material more accurate.

[0034] Working principle: When measuring the hardness of metal materials, the user moves the connecting frame 5 close to the first magnetic block 4, and fits the second magnetic block 6 and the first magnetic block 4 with the fixed frame 7 and the guide frame 8. The second magnetic block 6 and the first magnetic block 4 attract each other, thereby stabilizing the connecting frame 5, and then stabilizing the fixed frame 7. The fixed frame 7 is further supported by the support plate 9 to complete the installation of the fixed frame 7. The fixed frame 7 blocks the measuring instrument to play a protective role, and at the same time collects the debris generated during the measurement, and then uses the guide frame 8 to guide the debris, and effectively collects the debris into the fixed frame 7. In addition, the pressure sensor 12 is used to determine the pressure applied to the metal material, and the vertical distance between the pressure head 14 and the table 11 is determined by the scale 13. The table 11 containing the metal material has different shapes, so that the hardness of the metal material at different angles can be measured, thereby achieving the purpose of accurately detecting the bearing capacity of the metal material.
