AI Technical Summary
The existing metal Rockwell hardness testing table lacks a metal fixing device, which makes the metal easily knocked away during testing, posing a safety hazard. In addition, the movement of metal during the test causes the indenter to hit empty space, reducing the accuracy of the test.
Slide grooves and clamping blocks are set on the surface of the testing table. The clamping blocks can stably clamp the metal through the cooperation of connecting rods, sliders and springs to prevent the metal from flying out and moving.
It improves the safety and accuracy of metal Rockwell hardness testing and ensures the stability and precision of the testing process.

Abstract
Description
Technical Field
[0001] The utility model relates to testing equipment, in particular to a metal Rockwell hardness testing table. Background Art
[0002] A metal Rockwell hardness test bench is a device used to measure the Rockwell hardness of metal materials. It is usually supported by a sturdy metal frame and equipped with a height-adjustable platform.
[0003] Currently, existing metal Rockwell hardness testing platforms lack metal fixtures, making it easy for the indenter to be knocked off the test surface, resulting in safety accidents and significantly reducing the safety of metal Rockwell hardness testing. Furthermore, the impact of the indenter during testing can easily cause metal movement, resulting in the indenter striking empty, significantly reducing the accuracy of metal Rockwell hardness testing. Summary of the Invention
[0004] The technical problem to be solved by the present invention is how to solve the problem that the metal cannot be clamped and the indenter knocks it away during the test when performing the Rockwell hardness test on the metal, and how to solve the problem that the metal moves during the test, so as to ensure the safety and accuracy of the test.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a metal Rockwell hardness testing table, including a main body, an indenter is provided on the main body, a testing table is provided on the main body below the indenter, and at least three slide grooves are evenly arranged on the surface of the testing table along its center point. The slide grooves are hollowed out for the testing table, and a clamping block is provided on the top side of each slide groove, and each clamping block can move along the corresponding slide groove.
[0006] The bottom end of each clamping block is respectively provided with a connecting rod, which passes through the corresponding sliding groove and can move in the sliding groove. The bottom end of the connecting rod is provided with a slider, which passes through the sliding rod and can move along the sliding rod. One end of the sliding rod is connected to the fixed plate, and the other end of the sliding rod is connected to the detection platform. A spring is sleeved on the sliding rod between the slider and the detection platform, and the fixed plate is connected to the detection platform.
[0007] One end of the spring is connected to the slider, and the other end of the spring is connected to the detection platform.
[0008] This utility model utilizes the above-mentioned technical solution to design a metal Rockwell hardness testing platform. By installing a metal fixture, the platform effectively prevents metal from flying out during testing, thereby ensuring the safety of the testing process and improving the safety of metal Rockwell hardness testing. Furthermore, it effectively prevents the indenter from striking empty spaces due to metal movement during testing, thereby improving the stability of the testing process and thus enhancing the accuracy of metal Rockwell hardness testing.

[0014] The following is a detailed description of a metal Rockwell hardness testing platform of the present invention in conjunction with the accompanying drawings.
[0015] This utility model is a metal Rockwell hardness testing platform, see Figure 1 and Figure 2 The test bench comprises a main body 1, which is the overall structure of a metal Rockwell hardness test bench. An indenter 2 is provided on the main body 1 for testing the Rockwell hardness of metal. A test bench 3 is provided below the indenter 2 on the main body 1 for placing metal. Four chutes 4 are evenly arranged along the center of the test bench 3. The chutes 4 are hollowed out from the test bench 3. A clamping block 5 is provided on the top side of each chute 4 for clamping the metal. Each clamping block 5 can move along the corresponding chute 4.
[0016] The clamping block 5 can move along the corresponding sliding groove 4, see Figure 3 and Figure 4 Each clamping block 5 is provided with a connecting rod 6 at its bottom end. The connecting rod 6 passes through the corresponding chute 4 and can move within the chute 4. The bottom end of the connecting rod 6 is provided with a slider 7. The slider 7 is installed on a slide bar 9 and can move along the slide bar 9. One end of the slide bar 9 is connected to a fixed plate 8, and the other end of the slide bar 9 is connected to the testing platform 3. A spring 10 is sleeved on the slide bar 9 between the slider 7 and the testing platform 3. One end of the spring 10 is connected to the slider 7, and the other end of the spring 10 is connected to the testing platform 3. The spring 10 is used to perform elastic movement to push the slider 7. The fixed plate 8 is connected to the testing platform 3 and is used to install the movable structure of the clamping block 5.
[0017] During testing, the clamping block 5 is first pulled outward by human power. At this time, the clamping block 5 drives the slider 7 to move on the slide bar 9 through the connecting rod 6. As the slider 7 moves, it squeezes the spring 10, causing the spring 10 to perform elastic force-accumulating movement. The metal is then placed between the clamping blocks 5. Finally, the clamping blocks 5 are released. At this time, the spring 10 loses its resistance and performs elastic movement to push the slider 7 to the side again. The slider 7 drives the clamping block 5 to clamp the metal, thereby improving the stability of the metal and preventing the indenter 2 from knocking the metal away during testing, thereby preventing a dangerous accident. At the same time, it can also prevent the indenter 2 from causing the metal to move during testing, thereby preventing the indenter 2 from hitting the air, thereby enhancing the accuracy of the test and greatly improving the safety and test accuracy of the metal Rockwell hardness test bench.
