Detailed implementation manners

[0025] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application.

[0026] The metal hardness detection device of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0027] As Figures 1-6 shown, the metal hardness detection device of the embodiments of the present application may include a working frame 1, a detection device 2, a leveling abutting component 3, a limiting component 4, and two pre - installation components 5.

[0028] Among them, a base 10 is provided at the bottom of the working frame 1.

[0029] It can be understood that through the setting of the base 10, the stability of the device during detection can be ensured.

[0030] The detection device 2 is arranged on the working frame 1.

[0031] It should be noted that the detection device 2 described in this embodiment is a common metal hardness detection device 2 on the market, such as a Rockwell hardness tester, which uses a diamond cone or a hardened steel ball as an indenter. Under a certain initial test force, the indenter is pressed into the surface of the metal special-shaped part, and then the main test force is applied, and the indentation depth will increase. The hardness value is calculated according to the increased indentation depth.

[0032] The leveling and abutting assembly 3 is arranged on the working frame 1 and is located at the bottom of the detection device 2.

[0033] It should be noted that the leveling and abutting assembly 3 described in this embodiment can adjust the levelness so that the plane of the metal special-shaped part abuts on the leveling and abutting piece, enabling the detection part of the metal special-shaped part to be in a horizontal state during detection (when detecting the hardness of metal, if it is not placed flat, a series of significant drawbacks and problems will occur. First, the test results will deviate because uneven placement will cause uneven force distribution at the test point, thereby affecting the accuracy of the hardness value. This deviation may mislead subsequent material selection and use, and even have an adverse impact on the quality and safety of the product. Second, the position of the test point may also become inaccurate due to uneven placement, making the test results unable to truly reflect the hardness characteristics of the material. In addition, uneven placement may also increase the errors and uncertainties during the test, reducing the reliability and repeatability of the test. At the same time, long-term detection in an uneven state may also cause damage to the hardness tester itself and shorten its service life. Therefore, when performing metal hardness detection, it is necessary to ensure that the hardness tester and the sample to be tested are placed stably and horizontally to ensure the accuracy and reliability of the test results), thereby ensuring the detection effect of the metal special-shaped part.

[0034] The limiting assembly 4 is arranged on the working frame 1 and is located at the bottom of the leveling and abutting assembly 3.

[0035] It should be noted that the limiting assembly 4 described in this embodiment is used to limit and fix different types of metal special-shaped parts, so that relevant operators do not need to repeatedly disassemble and assemble the fixture, thereby reducing the labor intensity of relevant personnel and improving the detection efficiency of metal hardness.

[0036] Two pre-installation assemblies 5 are respectively arranged on the leveling and abutting assembly 3.

[0037] It should be noted that the pre-installation assembly 5 described in this embodiment is used to preliminarily support the metal special-shaped part, thereby improving the fixing efficiency of the metal special-shaped part and the detection efficiency of metal hardness.

[0038] Specifically, during the actual operation process, the relevant operators first adjust the detection device 2, and then adjust the leveling abutting component 3 to a horizontal position. After the adjustment is completed, the relevant operators abut the flat part of the metal special-shaped part against the leveling abutting component 3, so as to ensure that the part to be detected of the metal special-shaped part is in a horizontal state, thereby ensuring the hardness detection effect of the metal special-shaped part.

[0039] In addition, the relevant operators operate the limiting component 4 to abut against the bottom of the metal special-shaped part, and abut the flat surface of the part to be detected of the metal special-shaped part against the leveling abutting component 3. The relevant operators operate a controller (not shown in the figure), and the controller controls the detection device 2 to do work and performs hardness detection on the well-positioned metal special-shaped part. After the detection is completed, operate the limiting component 4 to make the limiting component 4 return to the initial position, and remove the metal special-shaped part. When detecting the next metal special-shaped part, repeat the above operations.

[0040] In an embodiment of the present application, as Figure 1 and Figure 3 shown, the leveling abutting component 3 may include two support plates 30, two leveling plates 31 and a bubble level 32.

[0041] Among them, the two support plates 30 are symmetrically arranged on both sides of the working frame 1 respectively;

[0042] The ends of the two leveling plates 31 are respectively arranged on the corresponding support plates 30, and there is a gap between the two leveling plates 31;

[0043] A plurality of fine adjustment bolts 310 are arranged on the leveling plate 31;

[0044] One end of the bubble level 32 is arranged on one leveling plate 31, and the other end of the bubble level 32 is arranged on the other leveling plate 31.

[0045] It can be understood that through the arrangement of the two support plates 30, a detection space is left between the support plates 30, thus facilitating the hardness detection of the metal special-shaped part.

[0046] It can be understood that through the detection space left between the two leveling plates 31, the hardness detection of the metal special-shaped part is further facilitated.

[0047] It should be noted that the statement that the ends of the two leveling plates 31 described in this embodiment are respectively arranged on the corresponding support plates 30 means that: one end of one of the two leveling plates 31 is arranged on one support plate 30, the other end of one leveling plate 31 is arranged on the other support plate 30, and one end of the other leveling plate 31 among the two leveling plates 31 is arranged on one support plate 30, and the other end of the other leveling plate 31 is arranged on the other support plate 30.

[0048] It can be understood that by setting a plurality of fine-tuning bolts 310, it is convenient to level the leveling plate 31.

[0049] It can be understood that by setting the bubble level 32, it is convenient for the operator to observe the horizontal position of the leveling plate 31.

[0050] It should be noted that the bubble level 32 described in this embodiment is a common horizontal detection component in the market, and its principle is based on gravity induction and the characteristic that the bubble maintains the highest position in the closed tube. Specifically, the mount of the bubble level 32 is flat. A longitudinally long circular curved glass tube is installed in the center of the mount, and sometimes a small horizontal glass tube is additionally attached to the left end. These glass tubes are filled with ether or alcohol and have a small bubble, which always remains at the highest point in the tube. When the bubble level 32 is placed on a plane, if the plane is completely horizontal, the bubble will be located at the center of the glass tube. This is because the gravity makes the bubble always tend to the highest point in the tube. If the plane is tilted, the bubble will move accordingly and deviate from the center position. By observing the degree of deviation of the bubble from the center, the tilting direction and angle size of the plane can be judged.

[0051] In an embodiment of the present application, as Figure 4 shown, the limiting component 4 may include a limiting plate 40 and a plurality of abutting mechanisms 41.

[0052] Among them, the limiting plate 40 is arranged on the working frame 1 and is located below the leveling abutting component 3, and a plurality of abutting mechanisms 41 are respectively arranged on the limiting plate 40.

[0053] It can be understood that the plurality of abutting mechanisms 41 are used to abut against different positions at the bottom of the metal special-shaped part, so as to ensure the limiting and fixing effect of the metal special-shaped part and ensure the detection quality of the metal special-shaped part.

[0054] In an embodiment of the present application, as Figure 5 shown, the abutting mechanism 41 may include a sleeve 410, an abutting rod 411, a first spring 412 and a fastening bolt 413.

[0055] Among them, the sleeve 410 is inserted into the limiting plate 40, the abutting rod 411 is arranged in the sleeve 410, the first spring 412 is arranged in the sleeve 410, one end of the first spring 412 is connected to the sleeve 410, the other end of the first spring 412 is connected to the abutting rod 411, and the fastening bolt 413 is threadedly connected to the sleeve 410 and is in threaded rotational abutment with the abutting rod 411.

[0056] It can be understood that by setting the sleeve 410, the abutting rod 411 can move up and down in the sleeve 410, and by setting the first spring 412, the abutting rod 411 can be telescoped and reset.

[0057] It is understandable that through the arrangement of the abutting rod 411, the telescopic movement of the abutting rod 411 is used to limit and fix the bottom of the metal special-shaped part for control.

[0058] It is understandable that through the arrangement of the fastening bolt 413, the position of the abutting rod 411 can be limited. Thus, after the abutting rod 411 abuts against one place at the bottom of the metal special-shaped part, by tightening the fastening bolt 413, the position of the abutting rod 411 is limited, thereby ensuring the fixing effect of the metal special-shaped part.

[0059] In an embodiment of the present application, as Figure 1 and Figure 6 shown, the pre-installation assembly 5 may include a fixing cylinder 50, a mounting plate 51, and a second spring 52.

[0060] Among them, the fixing cylinder 50 is arranged on the corresponding support plate 30. A sliding hole 500 is formed in the fixing cylinder 50. The mounting plate 51 passes through the sliding hole 500 and is slidably connected to the inner wall of the fixing cylinder 50. The second spring 52 is arranged in the fixing cylinder 50. One end of the second spring 52 is arranged on the fixing cylinder 50, and the other end of the second spring 52 is arranged on the mounting plate 51.

[0061] It is understandable that through the arrangement of the mounting plate 51, the two ends of the metal special-shaped part can be limited, so that it is not necessary for the relevant operator to hold the metal special-shaped part while adjusting the abutting rod 411, thereby improving the hardness detection efficiency of the metal special-shaped part.

[0062] In an embodiment of the present application, as Figures 1-6 shown, the usage method of the metal hardness detection device includes:

[0063] Step 1: Operate the pre-installation assembly 5 to perform preliminary limitation on the metal special-shaped part, and attach the flat part of the metal special-shaped part to the leveling plate 31 in the leveling and abutting assembly 3 that has been leveled.

[0064] Step 2: Operate each abutting rod 411 in the limiting assembly 4 to abut against the bottom of the metal special-shaped part, and tighten the corresponding fastening bolt 413, so as to limit the position of the abutting rod 411, and start the device to make the detection assembly detect the flat part of the metal special-shaped part.

[0065] Specifically, during the actual operation process, the relevant operator first adjusts the detection device 2, then adjusts the two leveling plates 31 to the horizontal position. The relevant operator abuts the flat part of the metal special-shaped part against the leveling plate 31, so as to ensure that the part to be detected of the metal special-shaped part is in a horizontal state, thereby ensuring the hardness detection effect of the metal special-shaped part.

[0066] In addition, the relevant operator operates each abutting rod 411 to abut against the bottom of the metal special-shaped part, and tightens the corresponding fastening bolt 413, so as to limit the position of the abutting rod 411. The relevant operator operates a controller (not shown in the figure), and the controller controls the detection device 2 to extend and perform work, and passes through the gap between the two leveling plates 31 to abut against the surface of the metal special-shaped part, so as to perform a hardness test on the well-positioned metal special-shaped part. After the test is completed, the fastening bolt 413 is loosened, and the abutting rod 411 returns to its initial position under the action of the first spring 412, and the metal special-shaped part is removed. When testing the next metal special-shaped part, repeat the above operations.

[0067] In summary, the metal hardness detection device according to the embodiment of the present application can be applicable to the clamping and fixing of different metal special-shaped parts, thereby reducing the labor intensity of relevant operators and improving the detection efficiency of metals.
