Description

Technical Field

[0001] The utility model relates to the technical field of Brinell hardness testers, in particular to a visual Brinell hardness tester capable of digital magnification. Background Art

[0002] The Brinell hardness test is a test method with the largest indentation among all hardness tests. It can reflect the comprehensive performance of the material and is not affected by the microscopic segregation and uneven composition of the sample structure. It is a hardness test method with higher precision.

[0003] The Brinell hardness tester operates by pressing a steel ball of a specified diameter into the surface of a specimen at a specified speed under a specified test force. After a specified period of time, the test force is removed and the Brinell hardness value of the specimen is calculated by measuring the diameter of the indented ball. It is primarily used for hardness determination of materials such as cast iron, steel, non-ferrous metals, and soft alloys. Because the Brinell hardness test produces a large indentation, the test process is complex, the indentation measurement is time-consuming, and the measurement error is relatively large, requiring the operator to possess proficient experimental techniques and extensive experience.

[0004] Existing Brinell hardness testers generally measure the indentation diameter through a mechanical eyepiece, which requires high experimental skills and experience of the operator. Since the image cannot be magnified, using the eyepiece for a long time will also affect the user's vision. Summary of the Invention

[0005] According to an embodiment of the present invention, a digitally magnifiable visual Brinell hardness tester is provided, comprising:

[0006] Visual Brinell hardness tester;

[0007] Test bench, the test bench is set on the visual Brinell hardness tester;

[0008] The steel ball indenter is set on the visual Brinell hardness tester. It presses into the test sample under the control of the visual Brinell hardness tester and unloads after holding the load for a period of time.

[0009] The lens is set on the visual Brinell hardness tester and can switch positions with the steel ball indenter under the control of the visual Brinell hardness tester;

[0010] The camera is directly opposite to the lens and rotates with the rotation of the lens, and is used to capture the indentation image information in real time and transmit it;

[0011] The mainboard is provided with an image processing module for zooming and amplifying the indentation image information transmitted by the camera received by the mainboard;

[0012] The display module receives the zoom-enlarged indentation image information and presents a real-time indentation image.

[0013] Furthermore, it also includes: a measuring knob, which is arranged on the visual Brinell hardness tester.

[0014] Furthermore, the mainboard is connected to the display module and the camera via a video cable.

[0015] Furthermore, the display module includes: a screen, which is arranged on the visual Brinell hardness tester.

[0016] Furthermore, the visual Brinell hardness tester has an inverted "concave" structure.

[0017] The present invention utilizes a digitally magnified visual Brinell hardness tester. Improvements have been made to the existing optical system by installing a variable-focus CMOS / CCD camera in place of the eyepiece. The camera captures indentation images in real time and transmits them to an image processing unit on the mainboard. This unit then magnifies the indentation image to varying sizes and projects it onto a display screen, allowing the operator to measure the indentation diameter. A measurement knob is also provided next to the screen for user convenience. This reduces operator workload while minimizing vision impairment.
