Description

Technical Field

[0001] The utility model relates to the field of hardness testers, in particular to a multi-specification hardness tester. Background Art

[0002] A multi-specification hardness tester is a hardness tester that can convert and measure between multiple hardness scales. This device can simultaneously support multiple hardness test standards, such as Rockwell, Brinell, Vickers, etc.

[0003] Application number: CN202321259083.7, discloses a hardness tester base and hardness tester. In this utility model, a handheld mechanism is provided. The base bracket and base bottom plate in the handheld mechanism are made of steel and coated with an anti-corrosion coating. The handheld mechanism optimizes the material and design of the hardness tester base and is made of materials with high strength and corrosion resistance to ensure the accuracy and stability of subsequent tests. The anti-drop support rod, anti-drop rubber head and rubber base in the handheld mechanism are protective structures for the hardness tester base. When the hardness tester base falls, the anti-drop support rod and The anti-drop rubber tip will fall to the ground first. The anti-drop support rod and the anti-drop rubber tip serve as a protective medium between the hardness tester base and the ground, effectively improving the durability and practicality of the hardness tester base as a whole. The base bracket and base bottom plate in the handheld mechanism are both hollowed out, which reduces the overall weight of the hardness tester base. When used with the handheld handle, the hardness tester base can be quickly moved, making it convenient to measure the hardness of large or horizontal objects that are difficult to move. In summary, the hardness tester base is made of high-strength steel and has undergone surface anti-corrosion treatment, which has high stability and high hardness value.

[0004] However, the physical properties of the material, such as hardness, elastic modulus and thermal expansion coefficient, will change with temperature. Therefore, temperature will have a certain impact on the test results of the hardness tester. Most existing hardness testers are difficult to compensate for temperature, which may affect the accuracy of the hardness tester. For this reason, we propose a multi-specification hardness tester. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a multi-specification hardness tester. By setting a temperature compensation component, the temperature of the test bench is detected by a thermometer on the test bench, and compared with the test temperature required for different test materials. If the temperature difference is large, temperature compensation is performed. If the temperature of the test bench is lower than the test temperature required by the test material, valve one is opened, and a hot medium, such as hot water, hot oil, etc., is introduced into the medium-entry hose using a conveying pump body, and then the temperature of the test bench is detected by a thermometer until it is basically the same as the test temperature required by the test material. Conversely, if the temperature of the test bench is higher than the test temperature required by the test material, valve one is opened, and a cold medium, such as cooling water, cooling oil, etc., is introduced into the medium-entry hose using a conveying pump body, and then the temperature of the test bench is detected by a thermometer until it is basically the same as the test temperature required by the test material. This can prevent temperature from affecting the results of material hardness testing.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

The outer end of the test bench is fixedly connected to a thermometer, and the detection probe of the thermometer extends to the inside of the test bench.

[0009] By setting a temperature compensation component, the temperature of the test bench is detected by the thermometer on the test bench, and compared with the test temperature required by different test materials. If the temperature difference is large, temperature compensation is performed. If the temperature of the test bench is lower than the test temperature required by the test material, valve one is opened, and a hot medium, such as hot water, hot oil, etc., is introduced into the medium-entry hose using a conveying pump body, and then the temperature of the test bench is detected by a thermometer until it is basically the same as the test temperature required by the test material. Conversely, if the temperature of the test bench is higher than the test temperature required by the test material, valve one is opened, and a cold medium, such as cooling water, cooling oil, etc., is introduced into the medium-entry hose using a conveying pump body, and then the temperature of the test bench is detected by a thermometer until it is basically the same as the test temperature required by the test material. This can prevent temperature from affecting the results of material hardness testing.

[0010] Furthermore, the medium inlet hose extends to the outside of the Rockwell hardness tester base and is fixedly connected to the Rockwell hardness tester base.

[0011] Furthermore, the medium discharge hose extends to the outside of the Rockwell hardness tester base and is fixedly connected to the Rockwell hardness tester base.

[0017] 1. By setting up a temperature compensation component, use the thermometer on the test bench to detect the temperature of the test bench and compare it with the test temperature required by different test materials. If the temperature difference is large, perform temperature compensation. If the temperature of the test bench is lower than the test temperature required by the test material, open valve one, use the delivery pump body or the like to introduce hot medium, such as hot water, hot oil, etc., into the medium entry hose, and then use the thermometer to detect the temperature of the test bench until it is basically the same as the test temperature required by the test material. Conversely, if the temperature of the test bench is higher than the test temperature required by the test material, open valve one, use the delivery pump body or the like to introduce cold medium, such as cooling water, cooling oil, etc., into the medium entry hose, and then use the thermometer to detect the temperature of the test bench until it is basically the same as the test temperature required by the test material.

[0027] Reference Figure 1-Figure 5 As shown, the temperature compensation component 5 includes an annular tube 501, which is rotatably connected to the inside of the detection platform 2. The inner side of the annular tube 501 is fixedly connected with multiple connecting tubes 502. The lower end of the intermediate connecting tube 502 is fixedly connected with a medium inlet hose 503, and the lower end of the intermediate connecting tube 502 is fixedly connected with a medium outlet hose 504. The outside of the medium inlet hose 503 and the medium outlet hose 504 is fixedly connected with a positioning sleeve 505, and the positioning sleeve 505 extends to the outside of the detection platform 2 and is rotatably connected to the detection platform 2.

The outer end of the detection platform 2 is fixedly connected with a thermometer 508, and the detection probe of the thermometer 508 extends to the inside of the detection platform 2.

[0028] By setting the temperature compensation component 5, the temperature of the test platform 2 is detected by the thermometer 508 on the test platform 2, and compared with the detection temperature required by different test materials. If the temperature difference is large, temperature compensation is performed. If the temperature of the test platform 2 is lower than the detection temperature required by the test material, the valve 1 506 is opened, and a hot medium such as hot water, hot oil, etc. is introduced into the medium-entry hose 503 by using the delivery pump body, and then the temperature of the test platform 2 is detected by using the thermometer 508 until it is basically the same as the detection temperature required by the test material. On the contrary, if the temperature of the test platform 2 is higher than the detection temperature required by the test material, the valve 1 506 is opened, and a cold medium such as cooling water, cooling oil, etc. is introduced into the medium-entry hose 503 by using the delivery pump body, and then the temperature of the test platform 2 is detected by using the thermometer 508 until it is basically the same as the detection temperature required by the test material.

[0029] Reference Figure 1-Figure 5 As shown, the medium inlet hose 503 extends to the outside of the Rockwell hardness tester base 1 and is fixedly connected to the Rockwell hardness tester base 1 .

[0030] Reference Figure 1-Figure 5 As shown, the medium discharge hose 504 extends to the outside of the Rockwell hardness tester base 1 and is fixedly connected to the Rockwell hardness tester base 1 .

[0031] By setting up a medium discharge hose 504, opening valve 2 507, and cooperating with the pump body, the medium can be discharged.

[0032] Reference Figure 1 and Figure 5 As shown, the adjustment assembly 4 includes a handwheel 401 , which is rotatably connected to the upper end of the Rockwell hardness tester base 1 , and the inner thread of the handwheel 401 is connected to a threaded rod 402 .

[0033] Reference Figure 1 and Figure 5 As shown, the threaded rod 402 is threadedly connected to the Rockwell hardness tester base 1 , and the medium inlet hose 503 and the medium outlet hose 504 both pass through the threaded rod 402 and are movably connected to the threaded rod 402 .

[0034] Reference Figure 1 and Figure 5 As shown, the upper end of the threaded rod 402 is fixedly connected to a fixing sleeve 403 , the fixing sleeve 403 is fixedly connected to the lower end of the detection platform 2 , and the fixing sleeve 403 is rotatably connected to the positioning sleeve 505 .

[0035] By setting up the adjustment component 4, the interior of the threaded rod 402 is hollow, which is convenient for not causing movement interference with the medium hose. Turning the handwheel 401 drives the threaded rod 402 to rotate and move up and down, thereby driving the detection table 2 to rotate and move up and down, and adjusting the height of the detection table 2 according to the thickness of the material.

[0036] Reference Figure 1 As shown, the detection component 3 includes an upper bracket 301, which is fixedly connected to the upper end of the Rockwell hardness tester base 1, the lower end of the upper bracket 301 is detachably connected to the detection head 302, and the left end of the upper bracket 301 is fixedly connected to the operation panel 303.

[0037] By setting up the detection component 3, the Rockwell hardness tester is usually equipped with multiple detection heads 302, including a diamond cone test head: for HRC (Rockwell C scale) test, a steel ball test head: for HRB (Rockwell B scale) test, and other steel ball test heads: for other Rockwell scales (such as HRA, HRD, etc.). The test heads 302 can be installed and disassembled using screws or the like, and the mechanical structure inside the Rockwell hardness tester can also switch the test heads 302. Different scales and hardness conversions can be selected using the operation panel 303, and the required test force can be selected using the external knob.

[0038] Specific implementation process: First, the temperature of the test platform 2 is detected by the thermometer 508 on the test platform 2, and compared with the detection temperature required by different test materials. If the temperature difference is large, temperature compensation is performed. If the temperature of the test platform 2 is lower than the detection temperature required by the test material, the valve 1 506 is opened, and a hot medium such as hot water, hot oil, etc. is introduced into the medium inlet hose 503 by using a delivery pump body, etc., and the temperature of the test platform 2 is then detected by the thermometer 508 until it is basically the same as the detection temperature required by the test material. Conversely, if the temperature of the test platform 2 is higher than the detection temperature required by the test material, the valve 1 506 is opened, and a cold medium such as cooling water, cooling oil, etc. is introduced into the medium inlet hose 503 by using a delivery pump body, etc., and the temperature of the test platform 2 is then detected by the thermometer 508 until it is basically the same as the detection temperature required by the test material.

[0039] Then use the operation panel 303 to select the scale, place the test material on the test table 2, turn the external knob to select the required test force, turn the handwheel 401, drive the threaded rod 402 to rotate and move up and down, thereby driving the test table 2 to rotate and move up and down, adjust the height of the test table 2 according to the thickness of the material, and finally use the detection head 302 to perform the test.
