Technical Field

[0001] The utility model relates to the technical field of test platforms, and more specifically, the utility model relates to an adjustable test platform for a Rockwell hardness tester. Background Technique

[0002] The Rockwell hardness tester is one of the most commonly used and convenient devices in the world for testing the hardness of metals. This device is designed based on the principle of the Rockwell hardness test and can quickly and accurately measure the hardness values of various metal materials. Due to its simple operation, accurate measurement results, and wide application range, the Rockwell hardness tester has become an indispensable detection tool in the industrial field. However, in actual use, there are still some drawbacks. For example, when testing some metal blocks with irregular shapes, the contact surface between the probe of the Rockwell hardness tester and the metal block is not a plane, and there is a certain angle between the measured surface and the probe. Measuring in this case will result in inaccurate results.

[0003] Therefore, an adjustable test platform for a Rockwell hardness tester is proposed to solve the above problems. Content of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides an adjustable test platform for a Rockwell hardness tester to solve the problem that when testing some metal blocks with irregular shapes in the prior art, the contact surface between the probe of the Rockwell hardness tester and the metal block is not a plane, and there is a certain angle between the measured surface and the probe, resulting in inaccurate results.

[0005] To solve the above technical problems, the utility model provides the following technical solution: An adjustable test platform for a Rockwell hardness tester, including a Rockwell hardness tester main body, a probe is arranged above the Rockwell hardness tester main body, a lifting platform is installed below the Rockwell hardness tester main body, and an angle adjustment component is installed on the top of the lifting platform;

[0006] The angle adjustment component includes a fixed disk, a connecting rod, a fixed frame, and a worm gear. The bottom of the fixed disk is fixedly connected to the top of the probe. A reference scale is arranged on the front of the fixed disk. The connecting rod and the connecting shaft are rotatably connected to the fixed disk. An indicating needle is fixedly installed at the top of the connecting rod. A placing table is fixedly connected to the top of the connecting rod. The fixed frame is fixedly installed on the back of the probe. A worm is rotatably connected inside the fixed frame. A rotating handle is fixedly installed at one end of the worm. The worm gear is fixedly connected to one end of the connecting shaft, and the worm gear meshes with the worm.

[0007] Wherein, the indicating needle moves along with the rotation of the connecting rod. By observing the position indicated by the indicating needle on the reference scale, it is convenient to level the measurement surface of the object.

[0008] Among them, it further includes a fixing component, and the fixing component is arranged on the top of the placing table.

[0009] Among them, the fixing component includes two symmetrically arranged support plates. Electric telescopic rods are fixedly installed on the opposite sides of the two support plates, and the end of the electric telescopic rod away from the support plate is fixedly connected with a clamping block.

[0010] Among them, one side of the clamping block is arranged in an arc shape to stably fix the sphere during detection.

[0011] The beneficial effects of the above technical solutions of the present utility model are as follows:

[0012] In the above solution, a Rockwell hardness tester main body, a probe, a lifting table, and an angle adjustment component are provided. An object is placed on the placing table. By rotating the rotating handle, the worm rotates inside the fixed frame. The rotation of the worm drives the worm wheel to rotate, and the worm wheel drives the connecting rod to rotate through the connecting shaft, so that the placing table and the detected object deflect. By observing the indicating needle and the reference scale, the detection surface of the object is adjusted to be flush. Finally, the lifting table is controlled to make the object contact with the probe for hardness detection. Through the above structure, the angle of the object to be measured can be adjusted, so that the detected surface of the irregular object remains flush during measurement, achieving the effect of improving the accuracy of the detection result;

[0013] The fixing component is provided. After the object to be detected is placed on the placing table, the electric telescopic rod is started, and the electric telescopic rod drives the clamping block to clamp the object. Through the above structure, the stability of the object during the adjustment of the angle adjustment component is maintained, so that it will not slide out of the placing table, and at the same time, the stability of the object when contacting the probe is also ensured, achieving the effect of preventing the object from translating during the detection process and affecting the accuracy of the detection result.
