Description

Technical Field

[0001] The utility model relates to the technical field of hardness testers, and specifically relates to an anti-offset hardness tester with symmetrical limit. Background Technique

[0002] A hardness tester is a hardness testing instrument. The definition of hardness was first proposed by Réaumur for measuring the hardness of metals, which represents the ability of a material to resist the indentation of a hard object into its surface. It is one of the important performance indicators of metal materials. Generally, the higher the hardness, the better the wear resistance. The hardness test is one of the simplest and easiest test methods in mechanical property tests. In order to be able to use the hardness test to replace some mechanical property tests, a relatively accurate conversion relationship between hardness and strength is required in production. According to the principle, it can be divided into: Leeb hardness tester, Rockwell hardness tester, Brinell hardness tester, Shore hardness tester, Shaw hardness tester, Barcol hardness tester, microhardness tester, Mohs hardness tester, Vickers hardness tester, etc.

[0003] When detecting the hardness of a metal block, it is generally necessary to detect more than 2 positions to improve the detection result. When the existing hardness tester detects a metal substance, during the detection process, the metal substance is squeezed, resulting in easy movement of the metal offset and dropping, leading to inaccurate detection values, thereby reducing the detection accuracy and affecting the final result value.

When using this device, first place the raw material on the surface of the linkage slider 3, so that the raw material pushes the linkage slider 3 to slide down and compress the spring. The linkage slider 3 drives the two first magnets 4 to descend and correspond to the two second magnets 6. The first magnet 4 attracts the second magnet 6, so that the second magnet 6 drives the limit slide plate 5 and the fixed pressing plate 7 to slide to clamp and fix the raw material.

[0031] Two positioning blocks 2 are fixedly connected to the bottom surface of the opening of the installation outer frame 1. A groove is provided on the bottom surface of the opening of the installation outer frame 1, and the inner wall of the groove of the installation outer frame 1 is slidably connected with a linkage slider 3. A linkage anti-slip mechanism is provided in the opening of the installation outer frame 1, which sucks air and prevents slipping of the anti-slip suction cup 17 through the first toothed plate 12 driving the transmission gear 13 to rotate and then through the second toothed plate 14 and the piston column 15. During operation, the cylinder 8 drives the support plate 9 and the hardness tester body 10 to descend, so that the first toothed plates 12 on both sides of the support plate 9 descend and drive the transmission gear 13 to rotate, and the transmission gear 13 drives the second toothed plate 14 to slide upward.

[0032] Two first magnets 4 are fixed on the lower end side surface of the linkage slider 3. The linkage anti-slip mechanism includes a linkage baffle 11 which is slidably connected to the inner wall of the opening of the installation outer frame 1.

An anti-slip suction cup 17 is embedded on the surface of the fixed pressing plate 7. The piston column 15 is driven to slide upward by the second toothed plate 14, so that the piston column 15 pumps air through the connecting hose 16.

[0033] Two limit sliding plates 5 are slidably connected to the inside of the positioning block 2 and the installation outer frame 1. Second magnets 6 are arranged on the lower end side surface of the limit sliding plates 5. A fixed pressing plate 7 is slidably connected to the upper end side surface of the positioning block 2.

The anti-slip suction cup 17 is driven by the fixed pressing plate 7 to abut against the surface of the raw material. When the anti-slip suction cup 17 is pumped air by the connecting hose 16, negative pressure is generated inside the anti-slip suction cup 17 to adsorb the surface of the raw material, preventing the raw material from sliding and shifting during work. Finally, the support plate 9 drives the linkage baffle 11 and the hardness tester body 10 to descend together to detect the raw material.

[0034] Working principle: When using this symmetrically limited anti-offset hardness tester, first place the raw material on the surface of the linkage slider 3, so that the linkage slider 3 drives the first magnet 4 to slide downward to attract the second magnet 6. The limit sliding plate 5 and the fixed pressing plate 7 are driven by the second magnet 6 to clamp the raw material. The cylinder 8 drives the support plate 9 and the first toothed plate 12 to descend, so that the first toothed plate 12 drives the transmission gear 13 to rotate, and the transmission gear 13 drives the second toothed plate 14 to rise. The piston column 15 is driven to move by the second toothed plate 14, so that the connecting hose 16 extracts the air of the anti-slip suction cup 17. After negative pressure is generated inside the anti-slip suction cup 17, it adsorbs the raw material for anti-slip, increasing the overall practicability.
