Description

Technical Field

[0001] This utility model relates to the field of hardness tester equipment, and in particular to a combined hardness tester with easy material feeding. Background Technology

[0002] In the field of material hardness testing, traditional hardness testers have significant technical shortcomings. Firstly, material placement and positioning rely on manual adjustment and simple fixtures, which is not only cumbersome and inefficient but also makes it difficult to guarantee positioning accuracy. This leads to material displacement during testing, resulting in significant deviations in test results. Secondly, the lifting platform of the hardness tester lacks effective adsorption and fixation methods. When testing high-hardness materials or applying large testing forces, the platform's stability is insufficient, further affecting the accuracy and reliability of the test. Thirdly, after testing, the observation of indentations and data acquisition using traditional hardness testers are mostly done manually. This not only makes it difficult to quickly and accurately obtain indentation images and related data but also results in low analysis efficiency and is prone to human error. Utility Model Content

[0003] The purpose of this invention is to provide a modular hardness tester that is easy to discharge materials, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a combined easy-to-discharge hardness tester, comprising a housing and a connecting arm, a control panel on the connecting arm, a combined hardness testing mechanism below the connecting arm, a hydraulic lifting adsorption platform inside the housing, an auxiliary positioning mechanism on the housing, and a control platform on one side of the housing.

[0005] As a preferred embodiment of this utility model, the combined hardness testing mechanism includes a hardness indenter, a rotating connecting platform on one side of the hardness indenter, an angle adjustment frame below the rotating connecting platform, and a digital microscope movably mounted inside the angle adjustment frame.

[0006] As a preferred embodiment of this utility model, the hydraulic lifting adsorption platform includes a hydraulic lifting column, a working platform at the top of the hydraulic lifting column, a vacuum machine on one side of the hydraulic lifting column, a cavity at the top of the hydraulic lifting column, the vacuum machine being pneumatically connected to the cavity, and an adsorption hole on the working platform being pneumatically connected to the cavity.

[0007] In a preferred embodiment of this utility model, the auxiliary positioning mechanism includes a support ring, a motor mounted on the support ring, a support frame below the motor, a lead screw movably mounted between a pair of support frames, the output end of the motor being connected to the lead screw, a connecting ring movably mounted on the hydraulic lifting column, one side of the connecting ring being threadedly connected to the lead screw, a first hinge bracket mounted on the working platform, a pair of first hinge brackets mounted on both sides of the working platform, a connecting member movably mounted between the pair of hinge brackets, an auxiliary positioning frame mounted on the connecting member, a guide wheel mounted on the auxiliary positioning frame, a second hinge bracket mounted on the end of the connecting member away from the working platform, and a third hinge bracket mounted on both sides of the connecting ring, with a connecting rod movably hinged between the second and third hinge brackets.

[0008] As a preferred embodiment of this utility model, the control platform is provided with a display screen, which is electrically connected to the digital microscope, and the control platform is provided with a control handle, which is electrically connected to the rotary connection table.

[0009] Compared with the prior art, the above-mentioned technical solution of this type has the following beneficial technical effects:

[0010] 1. The auxiliary positioning mechanism uses a motor-driven lead screw to pre-fix the material in the auxiliary positioning frame. Combined with the vacuum adsorption function of the hydraulic lifting adsorption table, it enables the material to be quickly positioned and firmly fixed. This facilitates material placement and improves material placement efficiency, while ensuring zero material displacement during testing and guaranteeing the accuracy of test results.

[0011] 2. The hydraulic lifting column drives the work platform to rise and fall smoothly. Combined with the double fixation of vacuum adsorption, it effectively enhances the stability of the platform and reduces test errors caused by shaking when testing high-hardness materials or applying large test forces.

[0012] 3. The control handle and display screen on the control platform enable precise control of the hardness testing mechanism and real-time high-definition display of indentation images. The hardness value is directly obtained through digital analysis and processing, avoiding human operation errors and greatly improving the efficiency of data acquisition and analysis.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] This utility model provides a technical solution: a combined, easy-to-discharge hardness tester, such as... Figure 1 , Figure 2 As shown, it includes a housing 1 and a connecting arm 2. The connecting arm 2 is equipped with a control panel 3. The connecting arm 2 is equipped with a combined hardness testing mechanism 4 below it. The housing 1 is equipped with a hydraulic lifting adsorption platform 5. The housing 1 is equipped with an auxiliary positioning mechanism 6. The housing 1 is equipped with a control platform 7 on one side.

[0021] like Figure 4 As shown, the combined hardness testing mechanism 4 includes a hardness indenter 401, a rotating connecting platform 402 on one side of the hardness indenter 401, an angle adjustment frame 403 below the rotating connecting platform 402, and a digital microscope 404 movably installed inside the angle adjustment frame 403.

[0022] like Figure 5 As shown, the hydraulic lifting adsorption table 5 includes a hydraulic lifting column 501, a working platform 502 on the top of the hydraulic lifting column 501, a vacuum machine 503 on one side of the hydraulic lifting column 501, a cavity 504 at the top of the hydraulic lifting column 501, the vacuum machine 503 being pneumatically connected to the cavity 504, and an adsorption hole 505 on the working platform 502 being pneumatically connected to the cavity 504.

[0023] like Figures 3-5As shown, the auxiliary positioning mechanism 6 includes a support ring 601, a motor 602 mounted on the support ring 601, a support frame 603 below the motor 602, a lead screw 604 movably mounted between a pair of support frames 603, the output end of the motor 602 being connected to the lead screw 604, a connecting ring 605 movably mounted on the hydraulic lifting column 501, one side of the connecting ring 605 being threadedly connected to the lead screw 604, a first hinge bracket 606 mounted on the working platform 502, a pair of first hinge brackets 606 mounted on both sides of the working platform 502, a connecting member 607 movably mounted between the pair of hinge brackets, an auxiliary positioning frame 608 mounted on the connecting member 607, a guide wheel 609 mounted on the auxiliary positioning frame 608, a second hinge bracket 610 mounted at the end of the connecting member 607 away from the working platform 502, and a third hinge bracket 611 mounted on both sides of the connecting ring 605, a connecting rod 612 movably hinged between the second hinge bracket 610 and the third hinge bracket 611.

[0024] like Figure 1 , Figure 2 As shown, the control platform 7 is equipped with a display screen 701, which is electrically connected to the digital microscope 404. The control platform 7 is also equipped with a control handle 702, which is electrically connected to the rotary connecting stage 402.

[0025] In practice, the motor 602 is started, causing the lead screw 604 to rotate forward. The rotation of the lead screw 604 causes the connecting movable ring 605 to move on the hydraulic lifting column 501. The connecting movable ring 605 drives the connecting piece 607 and the auxiliary positioning frame 608 to move through the connecting rod 612, so that the guide wheel 609 on the auxiliary positioning frame 608 contacts and initially fixes the edge of the test material, completing the pre-positioning of the material.

[0026] Start the vacuum machine 503. The vacuum machine 503 generates suction through the cavity 504 and the adsorption hole 505, which firmly adsorbs the pre-positioned material onto the working platform 502, ensuring that the material will not move during the test.

[0027] Using the control handle 702 on the control platform 7, the rotating connecting table 402 is rotated to adjust the hardness indenter 401 to a suitable testing position. At the same time, the image captured by the digital microscope 404 on the display screen 701 is observed to further fine-tune the position of the hardness indenter 401, ensuring it is precisely aligned with the test point of the test material.

[0028] The hydraulic system is activated, causing the hydraulic lifting column 501 to rise, which in turn moves the working platform 502 and the test material upwards, bringing the test material into contact with the hardness indenter 401. The hydraulic system applies a certain pressure, causing the hardness indenter 401 to press into the test material. After maintaining this pressure for a period of time, the hydraulic lifting column 501 descends, and the working platform 502 and the test material return to their initial positions.

[0029] The indentations on the test material are observed using a digital microscope 404, and the images are transmitted to a display screen 701. Based on the size and shape of the indentations, data analysis and processing are performed on the control platform 7 to determine the hardness value of the test material.

[0030] After the test is completed, turn off the vacuum machine 503 to release the adsorption on the test material. Restart the motor 602 to drive the lead screw 604 to reverse. The reverse rotation of the lead screw 604 drives the connecting movable ring 605 to move in the opposite direction, which, through the connecting rod 612, returns the auxiliary positioning frame 608 to its initial position, making it easy to remove the test material.

[0031] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
