[0013] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0014] Example 1 This utility model provides a stainless steel plate hardness testing machine, such as... Figures 1 to 4As shown, the system includes: a main body 1, an industrial display screen 2, and testing components. The main body 1 supports the stainless steel plate hardness tester. The industrial display screen 2 is located on the main body 1 and is used to visually display the hardness value. The testing components include a drive unit 3, a guide unit 4, a lifting unit 5, a test table 6, a test piece 7, and a microscope mechanism 8. The drive unit 3 is rotatably mounted on the main body 1. The drive unit 3 can be a drive turntable, with one end of the drive turntable connected to a manual screw jack. The manual screw jack is located inside the main body 1, and its output end is connected to the lifting unit 5. The guide unit 4 is inserted into the main body 1. 4 can be a guide ring, and the lifting component 5 is movably set on the guide component 4. The lifting component 5 can be a lifting rod. The test platform 6 is connected to the lifting component 5. The detection component 7 is set on the body 1. The detection component 7 is composed of a high-magnification optical measuring device, an optical dual-channel device, and photoelectric and photocouple sensors. The microscope mechanism 8 is set on the body 1. The driving component 3 drives the test platform 6 to move in the vertical direction through the lifting component 5. The center of the guide component 4 and the center of the lifting component 5 are on the same vertical line. The guide component 4 and the lifting component 5 are set correspondingly. The detection component 7 is located above the test platform 6. The detection component 7 and the test platform 6 are set correspondingly.

[0015] By using the test components, the height of the test platform 6 can be adjusted as needed, providing accurate height conditions for hardness testing, thereby ensuring the accuracy of test results and improving the reliability of the equipment.

[0016] In use, the operator rotates the drive unit 3, which drives the connected manual screw jack. The output end of the manual screw jack pushes the lifting unit 5 to rise vertically. Under the constraint of the guide unit 4, the lifting unit 5 ensures that the movement trajectory remains vertical, thus preventing positional deviation during movement. The movement of the lifting unit 5 drives the test platform 6 to move synchronously, causing the test platform 6 to lift the test plate synchronously. As the test platform 6 moves, it brings the test plate into contact with the test piece 7 and performs a hardness indentation test. The high-magnification optical measurement device, optical dual-channel device, and photoelectric and photocouple sensors inside the test piece 7 work together to accurately measure the indentation and calculate the hardness value. Finally, the results are displayed intuitively on the industrial display screen 2. The microscope mechanism 8 can be used to assist in observing the indentation morphology.

[0017] Specifically, an industrial display screen 2 is fixedly installed at the bottom of one end of the machine body 1, a microscope mechanism 8 is fixedly installed at the top of one end of the machine body 1, a drive component 3 is rotatably connected inside the machine body 1, the outer surface of the guide component 4 is inserted into the inside of the machine body 1, the outer surface of the lifting component 5 is movably connected to the inside of the guide component 4, the bottom end of the test platform 6 is fixedly connected to the top end of the lifting component 5, and a test component 7 is fixedly installed inside the machine body 1 at a position above the test platform 6.

[0018] To improve the stability of the test material, such as Figures 1 to 4As shown, it also includes a positioning assembly, which includes a telescopic component 9, a movable component 10, a pressing component 11, and a rubber component 12. The telescopic component 9 is set on the test bench 6. The telescopic component 9 can be an electric telescopic rod, which is formed by the movable insertion of two rod-shaped objects. The inside is filled with hydraulic oil. The extension and retraction of the two rod-shaped objects are achieved by the injection and extraction of hydraulic oil. This is existing technology and will not be described in detail here. The telescopic component 9 is electrically connected to the industrial display screen 2. There are four telescopic components 9, which are located at the four corners of the test bench 6. The movable end of the telescopic component 9 is driven to be connected to the movable component 10. The movable component 10 can be a movable rod. The movable component 10 is rotatably set on the telescopic component 9. The extrusion component 11 is connected to the movable component 10. The extrusion component 11 can be an extrusion plate. The rubber component 12 is bonded to the extrusion component 11. The rubber component 12 can be a rubber sheet. The telescopic component 9 drives the extrusion component 11 to move in the vertical direction through the movable component 10. Multiple telescopic components 9 are evenly spaced on the test platform 6. The rubber component 12 is located below the extrusion component 11 and keeps in contact with the test platform 6.

[0019] The positioning components work together to effectively and evenly press the test material, preventing it from sliding or lifting during the test, thus improving the stability of the test material and ensuring the accuracy of the test results.

[0020] In use, first place the test plate horizontally on the test platform 6. Then rotate the four extrusion parts 11 respectively, so that the extrusion parts 11 drive the movable parts 10 to rotate at the movable end of the telescopic parts 9. The rotation of the extrusion parts 11 drives the rubber parts 12 to rotate synchronously. When the rubber parts 12 are above the test plate, the position adjustment of the extrusion parts 11 is completed. Then start the telescopic parts 9. The movable end of the telescopic parts 9 begins to retract. The movable end of the telescopic parts 9 drives the movable parts 10 to move downward. The movement of the movable parts 10 drives the extrusion parts 11 and the rubber parts 12 to move downward synchronously. As the movable end of the telescopic parts 9 moves, the extrusion parts 11 drive the rubber parts 12 to press and adhere to the test plate, and fix it firmly on the test platform 6.

[0021] Specifically, multiple telescopic components 9 are fixedly installed inside the test bench 6. The movable end of the telescopic component 9 is rotatably connected to a movable component 10. The bottom end of the extrusion component 11 is fixedly connected to the top end of the movable component 10. A rubber component 12 is glued to the bottom end of the extrusion component 11. The rubber component 12 is located above the test bench 6.

[0022] Working principle: In actual use, the test plate is first placed horizontally on the test platform 6. Then, the four extrusion parts 11 are rotated, causing the extrusion parts 11 to drive the movable parts 10 to rotate at the movable end of the telescopic parts 9. The rotation of the extrusion parts 11 drives the rubber parts 12 to rotate synchronously. When the rubber parts 12 are above the test plate, the position adjustment of the extrusion parts 11 is completed. Then, the telescopic parts 9 are activated, and the movable end of the telescopic parts 9 begins to retract. The movable end of the telescopic parts 9 drives the movable parts 10 to move downward. The movement of the movable parts 10 drives the extrusion parts 11 and the rubber parts 12 to move downward synchronously. As the movable end of the telescopic parts 9 moves, the extrusion parts 11 drive the rubber parts 12 to press and adhere to the test plate, firmly fixing it on the test platform 6. This effectively and evenly presses the test plate, preventing the plate from sliding or lifting during the test, thereby effectively improving the stability of the test plate and ensuring the accuracy of the test results. Then, the operator rotates the drive unit 3, which drives the connected manual screw jack. The output end of the manual screw jack pushes the lifting unit 5 to rise vertically. Under the constraint of the guide unit 4, the lifting unit 5 ensures that its movement trajectory remains vertical, thus preventing positional deviation during movement. The movement of the lifting unit 5 drives the test platform 6 to move synchronously, causing the test platform 6 to lift the test plate synchronously. As the test platform 6 moves, it brings the test plate into contact with the test piece 7 and performs a hardness indentation test. The high-magnification optical measurement device, optical dual-channel device, and photoelectric and photocouple sensors inside the test piece 7 work together to accurately measure the indentation and calculate the hardness value. Finally, the results are displayed intuitively on the industrial display screen 2. The microscope mechanism 8 can be used to assist in observing the indentation morphology and can adjust the height of the test platform 6 as needed, providing accurate height conditions for hardness testing, thus ensuring the accuracy of the test results and improving the reliability of the equipment.

[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
