Description

Technical Field

[0001] This utility model relates to the field of hardness testers, and in particular to a hardness tester that facilitates the capture of panoramic images of test specimens. Background Technology

[0002] A hardness tester is a precision instrument used to measure the hardness of materials. Hardness refers to a material's ability to resist external forces, such as indentation, scratching, and abrasion. It is an important parameter of a material's mechanical properties. Hardness testers are used to test the hardness of materials to ensure that they meet specific quality standards and performance requirements. Vickers hardness testers are suitable for measuring tiny indentations and are commonly used for materials such as metals and ceramics.

[0003] When testing specimens with a hardness tester, the panoramic camera equipped with the hardness tester can directly capture a single image of the specimen, which can quickly obtain a full-view image of the specimen. This method is suitable for specimens with small size or when detailed image capture is required. When the specimen is large or a higher resolution panoramic image is required, the panoramic camera can be used to take multiple pictures of different parts of the specimen, and then the software can be used to stitch these single pictures into a complete panoramic image.

[0004] In existing technologies, a camera is used to take panoramic or partial pictures of the specimen. However, when testing the hardness of the specimen, after the hardness tester is connected to the computer system, the camera is used to take pictures of the specimen surface. It is not possible to adjust the vertical position of the camera. Different specimen shapes and sizes may require different camera positions to obtain the best measurement results. If the camera cannot be adjusted, it cannot adapt to various types of specimens, thereby reducing the stability of the camera. To address this issue, a hardness tester that can conveniently take panoramic images of the specimen is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a hardness tester that facilitates the capture of panoramic images of test specimens. It aims to improve the problem that existing hardness testers that facilitate the capture of panoramic images of test specimens cannot adjust the position of the camera vertically and cannot provide buffering for its movement, thus reducing the stability of the camera.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a hardness tester for conveniently capturing panoramic images of test specimens, comprising a frame, a cross-shaped test platform on the surface of the frame, a turret rotatably connected to the surface of the frame, an indenter fixedly connected to the bottom of the turret, an objective lens on the surface of the turret, a support rod slidably connected to the inner wall of the frame, a support plate fixedly connected to the outer wall of the support rod, a camera at the bottom of the support plate, a coaxial light source at the bottom of the camera, a buffer groove on the inner wall of the frame, a fixed plate fixedly connected to the inner wall of the buffer groove, a blocking block fixedly connected to the side wall of the fixed plate, a lifting block fixedly connected to the outer wall of the support rod, a sliding rod fixedly connected to the inner wall of the buffer groove, a buffer spring sleeved on the outer wall of the sliding rod, a U-shaped plate fixedly connected to the top of the support rod, a pressing plate fixedly connected to the top of the U-shaped plate, and an electric push rod fixedly connected to the bottom of the pressing plate.

[0007] As a further description of the above technical solution:

[0008] The top of the lifting block near the blocking block is rounded.

[0009] As a further description of the above technical solution:

[0010] The two ends of the slide rod are fixedly connected to the inner wall of the buffer groove, and the inner wall of the lifting block is slidably connected to the outer wall of the slide rod.

[0011] As a further description of the above technical solution:

[0012] The fixed end of the electric push rod is fixedly connected to the top of the frame.

[0013] As a further description of the above technical solution:

[0014] The top end of the buffer spring is fixedly connected to the bottom of the lifting block, and the bottom end of the buffer spring is fixedly connected to the bottom of the inner wall of the buffer groove.

[0015] As a further description of the above technical solution:

[0016] The bottom of the support plate is provided with an installation groove, and a dial ring is rotatably connected to the inner wall of the installation groove. A two-way screw is fixedly connected to the end of the dial ring, and an L-shaped clamp is threadedly connected to the outer wall of the two-way screw. A U-shaped clamp is fixedly connected to the outer wall of the L-shaped clamp.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the L-shaped clamp is slidably connected to the inner wall of the mounting groove.

[0019] As a further description of the above technical solution:

[0020] The inner surface of the U-shaped clamp is adapted to the outer surface of the camera.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, an electric push rod drives a U-shaped plate, which in turn enables the support rod and the support plate to lift and lower the camera. The combination of the buffer groove, spring, lifting block, blocking block and other structures can provide a certain resistance buffer when the support rod descends, so that the camera can adjust its position up and down for shooting, while avoiding damage to the camera or the test piece caused by the impact of lifting and lowering, and improving the stability of the camera displacement.

[0023] 2. In this utility model, the rotation of the double lead screw is controlled by a dial ring, which makes the L-shaped clamp and the U-shaped clamp move closer or further apart, thus clamping or releasing the camera. This allows for quick assembly and disassembly of the camera from the frame, making it convenient to remove the camera from the frame for maintenance and improving subsequent shooting efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a hardness tester for conveniently capturing panoramic images of test specimens. It includes a frame 1, a cross-shaped test platform 2 on the surface of the frame 1, a turret 3 rotatably connected to the surface of the frame 1, an indenter 4 fixedly connected to the bottom of the turret 3, and two sets of objective lenses 5 arranged in a circular array with the indenter 4 about the center point of the turret 3 as the axis of symmetry. The two sets of objective lenses 5 are configured as a 10X objective lens and a 40X objective lens. The inner wall of the frame 1 is slidably connected to a support rod 8. There are four sets of support rods 8, which are arranged in a rectangular array on the top of the coaxial light source 6 to provide support. The outer wall of the support rod 8 is fixedly connected to a support plate 9. A camera 7 is set at the bottom of the support plate 9. A coaxial light source 6 is set at the bottom of the camera 7. A U-shaped plate 16 is fixedly connected to the top of the support rod 8. An extrusion plate 18 is fixedly connected to the top of the U-shaped plate 16. An electric push rod 17 is fixedly connected to the bottom of the extrusion plate 18. The fixed end of the electric push rod 17 is fixedly connected to the top of the frame 1.

[0035] Reference Figures 4-6The inner wall of the frame 1 is provided with buffer grooves 10. The number of buffer grooves 10 is twice that of the support rods 8. The buffer grooves 10 are arranged in pairs, mirror images of each pair of support rods 8 with the central axis as the axis of symmetry. The inner wall of the buffer groove 10 is fixedly connected to a fixing plate 12. The side wall of the fixing plate 12 is fixedly connected to a blocking block 13. The outer wall of the support rods 8 is fixedly connected to a lifting block 11. The top of the lifting block 11 near the blocking block 13 is rounded. Several groups of blocking blocks 13 are arranged on the fixing plate 12 at equal intervals. When the lifting block 11 moves up and down, it can engage with the blocking block 13. The upper and lower sides of the blocking block 13 are obliquely arranged on opposite sides. The inner wall of the buffer groove 10 is fixedly connected to the slide rod 14. The two ends of the slide rod 14 are fixedly connected to the inner wall of the buffer groove 10. The inner wall of the lifting block 11 is slidably connected to the outer wall of the slide rod 14. The outer wall of the slide rod 14 is fitted with a buffer spring 15. The top end of the buffer spring 15 is fixedly connected to the bottom of the lifting block 11, and the bottom end of the buffer spring 15 is fixedly connected to the bottom of the inner wall of the buffer groove 10.

[0036] Reference Figure 7 The bottom of the support plate 9 is provided with a mounting groove 19. The inner wall of the mounting groove 19 is rotatably connected to a dial ring 20. The end of the dial ring 20 is fixedly connected to a bidirectional lead screw 21. The outer wall of the bidirectional lead screw 21 is threadedly connected to an L-shaped clamping plate 22. The outer wall of the L-shaped clamping plate 22 is slidably connected to the inner wall of the mounting groove 19. The outer wall of the L-shaped clamping plate 22 is fixedly connected to a U-shaped clamping plate 23. The inner surface of the U-shaped clamping plate 23 is adapted to the outer surface of the camera 7. The dial ring 20 controls the forward and reverse rotation of the bidirectional lead screw 21, thereby driving the L-shaped clamping plate 22 and the U-shaped clamping plate 23 to provide limit on both ends of the camera 7, so that it can be quickly installed and removed from the frame 1.

[0037] Working principle: The hardness tester is connected to the computer via wires. The specimen is placed on the cross-shaped test stage 2. The cross-shaped test stage 2 is raised and lowered to bring it closer to the indenter 4. The indenter 4 applies pressure by rotating the turret 3 to bring it closer. Two sets of objective lenses 5 with different magnifications observe the surface of the specimen. The camera 7 takes pictures of the specimen through the window of the coaxial light source 6. The pictures are transmitted to the computer for testing and analysis. The electric push rod 17 is activated. The output end of the electric push rod 17 controls the extrusion plate 18 to move downward, so that the U-shaped plate 16 extrudes the four sets of support rods 8. The support rods 8 drive the camera 7 through the support plate 9. The camera 7 is raised and lowered on the surface of the frame 1. When the camera 7 is raised and lowered, the lifting block 11 engages with multiple sets of blocking blocks 13. Since the bottom of the lifting block 11 is not rounded, the lifting block 11 has a certain resistance when it descends. At the same time, the buffer spring 15 is compressed, which can provide buffer for the camera 7 when the four sets of support rods 8 drive it to descend. This allows the camera 7 to approach the specimen smoothly during the descent, avoiding the camera 7 from shifting position or the specimen from deforming due to sudden impact or vibration. This ensures that the camera 7 can be accurately aligned with the measurement area and improves the measurement accuracy.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
