Description

Technical Field

[0001] This application belongs to the technical field of measurement, and in particular relates to a Rockwell hardness testing system. Background Technology

[0002] Rockwell hardness is determined by pressing a hardness indenter of a specific size, shape, and material into the surface of a sample. Rockwell hardness is calculated using a specific formula based on the difference between the final indentation depth and the initial indentation depth, as well as some constants.

[0003] The indentation depth of Rockwell hardness is related to the cleanliness of the sample itself, the cleanliness of the indenter, and the cleanliness of the sample stage supporting the sample. If there is dirt or oil on the surface of the indenter or the sample stage, it may cause deviation in the measurement value.

[0004] In related technologies, operators manually clean the surface of the hardness test ball and the sample stage, resulting in low efficiency in hardness testing of the samples. Utility Model Content

[0032] In related technologies, there is a technical problem of low efficiency in testing the hardness of samples. This application provides a Rockwell hardness testing system 1000, which can at least partially solve the technical problem of low efficiency in testing the hardness of samples.

[0033] This application is described below with reference to the accompanying drawings and specific embodiments:

[0034] like Figure 1 As shown, the Rockwell hardness testing system 1000 includes a support plate 400, a Rockwell hardness tester 100, and a wiping mechanism 200. The Rockwell hardness tester 100 includes a body 110, an indenter 120 mounted on the body 110, and a sample stage 130. The indenter 120 and sample stage 130 are arranged opposite each other along the height direction. The body 110 is mounted on the support plate 400. The wiping mechanism 200 includes a wiping assembly 210 and a drive assembly 220. The drive assembly 220 is mounted on the support plate 400, and its output end is connected to the wiping assembly 210, driving the wiping assembly 210 to wipe the indenter 120 and the sample stage 130.

[0035] The body 110 supports the indenter 120 and the sample stage 130, and can drive the sample stage 130 to rise and fall, as well as the indenter 120 to rise and fall. The body 110 has various structures, as known to those skilled in the art, and may include components such as a handwheel, dial, loading handle, and variable loading handle. The indenter 120 is used to press into the surface of the sample under a predetermined load, forming an indentation. The sample stage 130 is used to support the sample under test. The sample stage 130 and the indenter 120 are arranged opposite each other in the height direction, so that the sample is located between the indenter 120 and the sample stage 130 during testing, supported by the sample stage 130, and can be pressed in by the indenter 120.

[0036] The Rockwell hardness tester 100 can be used as follows: After placing the sample on the sample stage 130, rotate the rotary handwheel of the body 110 to slowly raise the sample stage 130, gradually bringing the sample closer to the indenter 120. This process should be slow to avoid sudden impact from the indenter 120 on the sample. Next, observe the indicator dial of the body 110 and adjust the pointer on the dial to ensure consistent initial measurement conditions. When the indenter 120 is about to contact the sample (this can be determined by observing subtle changes in the dial pointer), pull forward. The loading handle of the motor body 110 applies the main load to the indenter 120. After loading is completed, the load is maintained for a period of time (depending on the specific model and test standard), and then the pointer position on the indicator dial is observed. After the pointer stabilizes, the indicated reading is the hardness value to be obtained. After loading is completed, the unloading handle is slowly and uniformly pushed back to remove the main load. Then the handwheel is released, the sample stage 130 is lowered, the sample position is moved, and a new position is selected to continue the test. After the test is completed, the sample is removed from the sample stage 130.

[0037] The wiping mechanism 200 is used to wipe the indenter 120 and the sample stage 130. Specifically, it wipes the surface of the pressure ball at the lower end of the indenter 120 and the upper surface of the sample stage 130 that contacts the sample. The wiping mechanism 200 includes a wiping assembly 210 and a driving assembly 220. The wiping assembly 210 is used for wiping, and the driving assembly 220 drives the wiping assembly 210 to move so that the wiping assembly 210 can wipe the indenter 120 and the sample stage 130.

[0038] With this design, before the sample is placed on the sample stage 130, the wiping component 210 is driven by the driving component 220 to move, so that the wiping component 210 automatically wipes the indenter 120 and the sample stage 130, which simplifies the cleaning work before hardness testing, improves the cleaning efficiency, and thus improves the hardness testing efficiency of the sample.

[0039] The operating state (movement or stop) of the drive component 220 can be manually controlled by setting buttons, etc. At the same time, the drive component 220 can also be electrically connected to the control module of the body 110, and the control module can automatically control the drive component 220 to move or stop according to preset conditions or instructions. This application does not limit this.

[0040] It is easy to understand that the parts of the wiping assembly 210 that come into contact with the pressure head 120 and the sample stage 130 can be made of soft materials such as cotton or rubber to prevent the wiping assembly 210 from scratching the pressure head 120 and the sample stage 130 during the wiping process.

[0041] In some embodiments, the wiping assembly 210 includes a support member 211 and a wiping member 212. One end of the support member 211 is connected to the output end of the drive assembly 220. The wiping member 212 is connected to the other end of the support member 211 and is used to wipe the pressure head 120 and the sample stage 130. The drive assembly 220 drives the support member 211 to move, and the support member 211 drives the wiping member 212 to move, thereby causing the wiping member 212 to wipe the pressure head 120 and the sample stage 130.

[0042] During the wiping process, the wiping element 212 will gradually wear down and needs to be replaced after a period of time. In some embodiments, the wiping element 212 is detachably connected to the support element 211. This design makes the replacement of the wiping element 212 more convenient. The operator does not need to disassemble the entire wiping assembly 210; they only need to simply disconnect the detachable connection between the wiping element 212 and the support element 211 to easily remove the worn wiping element 212 and quickly install a new one. The wiping element 212 and the support element 211 can be detachably connected by bolts, snap-fit, or other means, which is not limited in this application.

[0043] In some embodiments, the wiping member 212 includes a connecting portion 2121 and a wiping portion 2122. The connecting portion 2121 is detachably connected to the support member 211; the wiping portion 2122 is sleeved outside the connecting portion 2121 and is used to wipe the pressure head 120 and the sample stage 130. The connecting portion 2121 is elongated and can be made of materials such as wood, plastic, or metal, while the wiping portion 2122, sleeved outside the connecting portion 2121, can be made of materials such as cotton or rubber.

[0044] In some embodiments, along the height direction, the drive component 220 drives the wiping component 210 to rotate about a pivot parallel to the height direction. Under the action of the drive component 220, the wiping component 210 can switch between a first position located between the pressure head 120 and the sample stage 130 and a second position located outside the pressure head 120 and the sample stage 130.

[0045] The drive assembly 220 drives the wiping assembly 210 to rotate about an axis parallel to the height direction, that is, the drive assembly 220 drives the wiping assembly 210 to rotate horizontally.

[0046] It should be noted that before the drive assembly 220 is started, the distance between the pressure head 120 and the sample stage 130 needs to be adjusted so that the wiping part 2122 can pass smoothly and that the wiping part 2122 makes contact with both the pressure head 120 and the sample stage 130 during its passage. The distance between the pressure head 120 and the sample stage 130 can be adjusted manually by the operator, or it can be automatically adjusted by the control module of the machine body 110 according to preset conditions or instructions, which is not limited in this application.

[0047] The drive assembly 220 drives the wiping member 212 to rotate horizontally. When the wiping member 212 rotates to a position between the pressure head 120 and the sample stage 130, it contacts both the pressure head 120 and the sample stage 130, thereby wiping the pressure head 120 and the sample stage 130. After the wiping member 212 has finished wiping, the drive assembly 220 drives the wiping member 212 to be located outside the pressure head 120 and the sample stage 130, to avoid the wiping member 212 interfering with the sample being placed on the sample stage 130, and also to avoid interfering with the pressure head 120 pressing into the sample. Figure 1 A schematic diagram is shown when the wiping assembly 210 is in the first position.

[0048] In some embodiments, the driving assembly 220 includes a rotating member 221, the axis of which is parallel to the height direction and connected to the wiping assembly 210. Rotation of the rotating member 221's axis causes the wiping assembly 210 to rotate about the height direction.

[0049] The drive element 221 can be an electric motor, a pneumatic motor, etc. In some embodiments, the drive element 221 is an electric motor.

[0050] The heights of the indenter 120 and sample stage 130 of the Rockwell hardness tester 100 can be adjusted according to testing requirements. In some embodiments, the drive assembly 220 further includes a drive member 222, which is arranged along the height direction and mounted on the support plate 400. The output end of the drive member 222 is connected to the drive member 221 to drive the drive member 221 to move along the height direction. With this design, the drive member 222 can move the drive member 221 in the height direction, thereby allowing the wiping assembly 210 to move in the height direction. This allows the height of the wiping assembly 210 to be changed, enabling the wiping assembly 210 to flexibly adapt to the indenter 120 and sample stage 130 located at different heights. With this design, when the distance between the pressure head 120 and the sample stage 130 is large, the distance between the pressure head 120 and the sample stage 130 does not need to be adjusted before the drive component 220 is started. The height of the wiping component 210 can be adjusted by controlling the action of the drive component 222, so that the pressure head 120 and the sample stage 130 can be wiped separately. This makes it convenient for the wiping component 210 to wipe the pressure head 120 and the sample stage 130 at different heights, which helps to improve wiping efficiency.

[0051] The drive component 222 can be a cylinder, hydraulic cylinder, etc., and is not limited thereto in this application. In some embodiments, the drive component 222 is a linear motor.

[0052] In some embodiments, the Rockwell hardness testing system 1000 further includes a robotic arm 300 for holding the sample. The robotic arm 300 has various structures and is not limited thereto in this application. During testing, the robotic arm 300 automatically picks up the sample and places it on the sample stage 130. After the test is completed, the robotic arm 300 removes the sample from the sample stage 130. The robotic arm 300 facilitates sample loading and unloading operations, reduces the workload of testing personnel, and helps improve the efficiency of sample hardness testing.

[0053] The following is Figure 1 The apparatus shown illustrates the working principle of the Rockwell hardness testing system 1000 of this application:

[0054] Before testing the hardness of the sample, the drive component 222 is controlled to move, causing the wiping assembly 210 to move to a height that can contact the upper surface of the sample stage 130. Then, the drive component 221 is controlled to rotate, causing the wiping assembly 210 to rotate. During the rotation of the wiping assembly 210, it contacts the upper surface of the sample stage 130, thereby cleaning the upper surface of the sample stage 130. Similarly, the drive component 222 is controlled to move, causing the wiping assembly 210 to move to a height that can contact the lower spherical surface of the indenter 120. Then, the drive component 221 is controlled to rotate, causing the wiping assembly 210 to rotate. During the rotation of the wiping assembly 210, it contacts the lower spherical surface of the indenter 120, thereby cleaning the lower spherical surface of the indenter 120. Next, the robotic arm 300 picks up the sample and places it on the sample stage 130. Then, the rotating handwheel of the machine body 110 is rotated, causing the sample stage 130 to slowly rise, allowing the sample to gradually... Approaching the indenter 120 should be done slowly to avoid sudden impact on the sample. Next, observe the indicator dial of the machine body 110 and adjust the pointer to ensure consistent initial measurement conditions. When the indenter 120 is about to contact the sample (this can be determined by observing subtle changes in the dial pointer), pull the loading handle of the machine body 110 forward to apply the main load to the indenter 120. After loading, maintain the load for a period of time (depending on the specific model and test standard), then observe the pointer position on the indicator dial. Once the pointer stabilizes, the indicated reading is the desired hardness value. After loading, slowly and evenly push back the unloading handle to remove the main load. Then release the handwheel, lower the sample stage 130, and the robotic arm 30 moves the sample position to a new location to continue the test. After the test, the robotic arm 30 removes the sample from the sample stage 130.
