[0002] Rockwell hardness tester is a commonly used hardness testing instrument used to measure the hardness of materials. The principle of Rockwell hardness tester is based on the elastic rebound degree of the material surface after being subjected to force. During the test, a steel ball or diamond cone head with a certain pressure is pressed on the surface of the material to be tested, and then the indentation depth on the material surface or the depth of drill bit rebound is measured. The hardness value of the material is calculated through these values.

[0003] With the development of science and technology, Rockwell hardness tester has been gradually applied to many fields. However, the common Rockwell hardness tester lacks the function of clamping and positioning the test object during use, which may cause deviation and shaking during the test, resulting in inaccurate test data. However, if a clamping mechanism is simply added, when the object does not need to be clamped, the clamping mechanism cannot be disassembled, which is inconvenient and reduces the convenience of operation.

[0027] Embodiment 1

[0028] Combined with Figures 1 to 5 , a clamping mechanism for a portable Rockwell hardness tester, including a hardness tester body 1, a disassembly mechanism 2 is arranged inside the hardness tester body 1, and a pressing mechanism 3 is arranged on the front of the disassembly mechanism 2;

[0029] The disassembly mechanism 2 includes a fixed frame 21, the fixed frame 21 is fixedly connected to the inside of the hardness tester body 1, a limit groove 22 is fixedly connected to the inside of the fixed frame 21, a threaded rod 23 is rotatably connected to the inner wall of the limit groove 22, a threaded block 24 is threadedly connected to the outer wall of the threaded rod 23, a connecting plate 25 is fixedly connected to the top of the threaded block 24, a clamping block 26 is fixedly connected to one side of the connecting plate 25, and an insert block 27 is arranged on one side of the pressing mechanism 3.

[0030] Further, the outer shape of the threaded block 24 matches the inner wall shape of the limiting groove 22, and the threaded block 24 is slidably connected to the inner wall of the limiting groove 22, enabling the threaded block 24 to move stably.

[0031] Further, the threaded rod 23 penetrates through the right side of the limiting groove 22 and rotates. One end of the threaded rod 23 is fixedly connected with a handle, facilitating the rotation of the threaded rod 23 by driving the handle.

[0032] Further, the thread directions on the outer walls of both ends of the threaded rod 23 are opposite. A rectangular opening is formed on the outside of the fixed frame 21, and the clamping block 26 penetrates through the formed rectangular opening, enabling the clamping block 26 to move through the rectangular opening.

[0033] Further, a bayonet is formed on one side of the insertion block 27, and the clamping block 26 is inserted into the inner wall of the formed bayonet, enabling the clamping block 26 and the bayonet to cooperate with each other to limit the insertion block 27.

[0034] Embodiment 2

[0035] Refer to Figures 1 to 5 On the basis of Embodiment 1, the pressing mechanism 3 further includes a support box 31. The support box 31 is fixedly connected to the front of the insertion block 27. A spring 32 is fixedly connected to the inner wall of the support box 31. The bottom end of the spring 32 is fixedly connected to a rectangular plate 33. A connecting shaft 34 is fixedly connected to the bottom of the rectangular plate 33. The bottom end of the connecting shaft 34 is fixedly connected to a pressing plate 35, further improving the stability of pressing and limiting the material.

[0036] Further, the outer shape of the rectangular plate 33 matches the inner wall shape of the support box 31, and the rectangular plate 33 is slidably connected to the inner wall of the support box 31, enabling the rectangular plate 33 to move stably and compress the spring 32.

[0037] Further, a through hole is formed at the bottom of the support box 31, and the connecting shaft 34 penetrates through the formed through hole and moves, enabling the connecting shaft 34 to move through the formed through hole.

[0038] During the actual operation process, when this device is in use, first, when it is necessary to disassemble the pressing mechanism 3, the handle can be rotated to drive the threaded rod 23 to rotate. Since the threaded rod 23 and the threaded block 24 are threadedly connected, the rotational motion of the threaded rod 23 will be converted into the linear motion of the threaded block 24. At the same time, the threaded block 24 can slide and be limited inside the limiting groove 22. Therefore, the threaded block 24 will drive the clamping block 26 to disengage from the inside of the insertion block 27 through the connecting plate 25, canceling the limit on the insertion block 27. Immediately afterwards, the insertion block 27 can be pulled out from the inside of the fixed frame 21, achieving the disassembly of the pressing mechanism 3. When the clamping function is not required, good disassembly convenience can be achieved, and it is also convenient for the staff to operate and use, enhancing the practicality of the device.

[0039] The staff can place the material to be tested on the top of the frustum, and then drive the material to rise through the handle. When the material contacts the pressure plate 35, it will push the connecting shaft 34 upward. The connecting shaft 34 can drive the rectangular plate 33 to rise and compress the spring 32. Then, under the elastic action of the spring 32, the material can be tightly pressed and limited, ensuring the stability of the material during the test and preventing it from easily shaking or shifting, further improving the accuracy of the test data.

[0040] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent in such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
