Description

Technical Field

[0001] This utility model relates to the field of hardness tester stage technology, and in particular to an adjustable post-forging hardness measurement test bench. Background Technology

[0002] A hardness tester is an instrument for testing hardness. The measurement of metal hardness was first defined by Reomüller, representing a material's ability to resist indentation by a harder object. It is one of the important performance indicators of metallic materials. Generally, the higher the hardness, the better the wear resistance. Existing hardness testers are shown in the attached figure. Figure 1 As shown, a support plate is set below the testing end of the hardness tester to support the workpiece being tested. When in use, the handle on one side of the hardness tester is rotated to move the testing end down and press it onto the workpiece. The pressure on the workpiece and the pressure on the testing end are then observed to measure the hardness of the workpiece.

[0003] Currently, hardness testing often requires testing at various locations on a workpiece. However, the bearing area is insufficient. For long, irregularly shaped, or large workpieces (such as shafts and plates), the standard support plate is too small to fully support the workpiece, leading to uneven force distribution during testing and affecting the accuracy of hardness measurements. Furthermore, the support plate has poor anti-slip properties; its surface is usually smooth metal or hard material, making the workpiece prone to displacement or slippage under pressure. This is especially problematic when testing high-hardness materials, potentially causing data distortion or even equipment damage due to slippage. Existing technologies address these issues by replacing different models of support plates, but frequent replacements are not only cumbersome but can also introduce testing errors due to installation mistakes. Therefore, a multi-functional support plate suitable for workpieces of different sizes and shapes is needed.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the issues of poor functionality and cumbersome replacement procedures of existing hardness tester plates, this invention provides an adjustable post-forging hardness measurement test bench.

[0006] The adjustable post-forging hardness measuring test bench provided by this utility model adopts the following technical solution:

[0007] An adjustable post-forging hardness measuring test bench includes a hardness tester body and a support column. The support column is fixed to the bottom inner side of the hardness tester body, and a support frame is fixed to the top of the support column. An adjustable plate that can move up and down is provided on the inner side of the support frame. A spring is provided in the middle of the bottom surface of the adjustable plate and elastically connected to the inner wall of the support frame. A load plate that can slide left and right is provided above the support frame. The top surface of the load plate has a first panel, a second panel, and a third panel. A positioning plate is fixed to the bottom of the load plate. The bottom of the positioning plate has multiple positioning grooves. An insert plate is fixed to the top surface of the middle part of the adjustable plate. The top of the insert plate is inserted into the inner side of one of the positioning grooves to lock the position of the load plate.

[0008] Furthermore, an adjustment groove is provided transversely through the inner side of the support frame, and an adjustment plate passes through the adjustment groove. Guide columns are symmetrically fixed on the inner wall edge of the adjustment groove. Guide holes are symmetrically provided at both ends of the adjustment plate, and the guide columns pass through the guide holes. The adjustment plate can move stably up and down along the guide columns. A moving opening is provided at the top of the inner wall of the adjustment groove, and the moving opening passes through the support frame. An insert plate passes through the moving opening.

[0009] Furthermore, the top edge of the support frame is symmetrically fixed with a first L-shaped plate and a second L-shaped plate, and the bottom edge of the loading plate is symmetrically fixed with an inverted T-shaped sliding plate. The inverted T-shaped sliding plate is embedded between the first L-shaped plate and the second L-shaped plate, and the inverted T-shaped sliding plate can slide horizontally between the first L-shaped plate and the second L-shaped plate.

[0010] Furthermore, the top surface of the support frame is provided with multiple grooves, and a rotor is provided inside the grooves. The inverted T-shaped slide plate makes rolling contact with the rotor, and the inverted T-shaped slide plate can slide smoothly above the rotor.

[0011] Furthermore, a plurality of first silicone pads are fixed on the top surface of the first panel, an arc-shaped groove is provided in the middle of the top surface of the third panel, a plurality of second silicone pads are fixed on the inner wall of the arc-shaped groove, a detection end is provided on the inner top surface of the hardness tester body, the detection end is located above the carrier plate, and a movable handle is fixed on one side wall of the carrier plate.

[0012] Furthermore, a guide opening is provided below the positioning groove. The inner wall of the guide opening is inclined, and the spacing between adjacent guide openings is small, which facilitates the insertion of the insert plate into the inner side of the positioning groove. The top size of the insert plate is adapted to the positioning groove, and the plate blocks the load plate to make it stable.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] (1) The top surface of the carrier plate of this utility model is provided with three different base surfaces. One base surface is the same as the conventional hardness tester carrier plate, which meets the hardness testing requirements of standard flat workpieces. Multiple silicone pads are provided on the top of the base surface. The silicone pads increase the friction of the workpiece, making it less likely to slip when the workpiece is squeezed. It is especially suitable for smooth or easily displaced materials. Another base surface is provided with an arc-shaped groove, and the inner wall is also provided with silicone pads. It is designed for spherical or arc-shaped workpieces. The arc-shaped groove and the silicone pads work together to improve the fixing stability of irregular workpieces. The above base surface settings allow operators to test the hardness of workpieces without frequently changing the carrier plate, improving the testing stability and ease of use of the hardness tester. It also increases the top area of ​​the carrier plate to accommodate larger workpieces, making it more widely applicable.

[0015] (2) The adjustment plate of this utility model is connected to the support frame by a spring, and the cooperation between the insert plate and the positioning groove realizes the quick locking of the carrier plate. The engagement of the inverted T-shaped slide plate and the L-shaped plate ensures that the carrier plate moves horizontally without deviation. At the same time, the rotor assists the carrier plate to slide and reduce friction, making the operation smoother. When changing different carrier surfaces for the workpiece, the carrier plate switching is both flexible and stable, which is especially suitable for industrial scenarios where the detection objects need to be frequently changed.

[0023] The following is in conjunction with the appendix Figure 1-6 This utility model is further described in detail below. An adjustable post-forging hardness measuring test bench includes a hardness tester body 1 and a support column 2. The support column 2 is fixed to the inner bottom surface of the hardness tester body 1, and a support frame 3 is fixed to the top of the support column 2. A sliding plate 4 is provided above the support frame 3. A detection end 11 is provided on the inner top surface of the hardness tester body 1, located above the plate 4. In actual use, the workpiece is placed on the plate 4, positioned below the detection end 11. Then, following the conventional hardness tester method, the rotating handle on the side wall of the hardness tester is rotated to press the detection end 11 down on the workpiece. Simultaneously, the pressure is displayed on the screen on the side wall of the hardness tester. The operator can then determine the workpiece hardness by combining the pressure and the workpiece indentation.

[0024] Example 1: In this example, refer to Figure 1 and Figure 4 As shown, specifically, the top surface of the carrier plate 4 is provided with a first panel 41, a second panel 42 and a third panel 43. The top surface of the first panel 41 is fixed with multiple first silicone pads 411, which can be made of common silicone material and are relatively thin, only providing friction. The second panel 42 is the same as the conventional hardness tester stage and is a smooth surface. The top surface of the third panel 43 is provided with an arc groove 431 in the middle, which is suitable for spherical or workpieces with arc plates. The inner wall of the arc groove 431 is fixed with multiple second silicone pads 432, which also increases friction. The combination of the three surfaces increases the area of ​​the carrier plate 4. A movable handle 44 is fixed to one side wall of the carrier plate 4 for pulling the carrier plate 4.

[0025] Specifically, through the above technical solution, when the operator performs hardness testing on the workpiece, the operator can place the workpiece on different platforms of the carrier plate 4 according to the actual needs of the workpiece. The multi-functional carrier plate 4 can be used to adapt and test workpieces of different shapes and sizes without the need for the operator to temporarily change the carrier plate 4, which is suitable for industrial scenarios that require frequent switching of test objects.

[0026] Example 2: In this example, refer to Figure 1 Figure 4 and Figure 6As shown, specifically, the inner side of the support frame 3 is provided with an adjustable plate 5 that can move up and down. It can move up and down inside the adjustment groove 34 of the support frame 3. The bottom of the adjustable plate 5 is provided with a spring 52 that is elastically connected to the inner wall of the support frame 3. The spring 5 is a pre-compressed spring, and its initial elastic force can ensure that the insert plate 53 and the positioning groove 451 are tightly engaged. The elastic support of the spring 52 ensures that the insert plate 53 always maintains contact pressure with the positioning groove 451, avoiding accidental dislocation due to external force. The bottom of the carrying plate 4 is fixed with a positioning plate 45. The bottom of the positioning plate 45 is provided with multiple positioning grooves 451, which can be inserted and fixed according to the movement of the carrying plate 4. The top surface of the middle part of the adjustable plate 5 is fixed with an insert plate 53. The top of the insert plate 53 is inserted into the inner side of one of the positioning grooves 451 to lock the position of the carrying plate 4. The top size of the insert plate 53 is adapted to the positioning groove 451. The tight fit between the insert plate 53 and the positioning groove 451 effectively prevents the carrier plate 4 from shaking and ensures the stability of the workpiece during inspection. The carrier plate 4 is fixed and stable by the shielding of the insert plate 53. The inner side of the support frame 3 is provided with an adjustment groove 34, and the adjustment plate 5 passes through the adjustment groove 34. The top of the inner wall of the adjustment groove 34 is provided with a moving port 36, which passes through the support frame 3 and the insert plate 53 passes through the moving port 36. The inner wall of the adjustment groove 34 is symmetrically fixed with guide posts 35. The two ends of the adjustment plate 5 are symmetrically provided with guide holes 51, and the guide posts 35 pass through the guide holes 51. The symmetrical cooperation between the guide posts 35 and the guide holes 51 ensures that the adjustment plate 5 moves vertically up and down, avoids the problem of tilting when pressing down on one side, and improves the smoothness and reliability of the operation.

[0027] Specifically, through the above technical solution, the adjusting plate 5 is connected to the support frame 3 via the spring 52, and the insert plate 53 is engaged with the positioning groove 451 to achieve quick locking of the carrier plate 4. When the operator changes the table surface of the carrier plate 4 according to the workpiece, the up and down movement design of the adjusting plate 5 allows the insert plate 53 to quickly switch the positioning groove 451, realizing the movement and step-like fixing of the table surface of the carrier plate 4. The adjustment operation is convenient and the fixing is stable. At the same time, the adjusting plate 5, the support frame 3 and the carrier plate 4 are mostly made of rigid materials, with high support strength and long service life.

[0028] Example 3: In this example, refer to Figure 2 and Figure 3As shown, specifically, the top edge of the support frame 3 is symmetrically fixed with a first L-shaped plate 31 and a second L-shaped plate 32, arranged symmetrically in pairs. The bottom edge of the carrying plate 4 is symmetrically fixed with an inverted T-shaped sliding plate 46, which is embedded between the first L-shaped plate and the second L-shaped plate. The inverted T-shaped sliding plate can slide horizontally between the first L-shaped plate and the second L-shaped plate, and the connection is stable, so that the carrying plate 4 is not easy to shake when it slides. The inverted T-shaped sliding plate 46 can slide left and right between the first L-shaped plate 31 and the second L-shaped plate 32. The top surface of the support frame 3 is provided with multiple grooves, and the inner side of the grooves is provided with a rotor 33. The inverted T-shaped sliding plate 46 rolls in contact with the rotor 33, and the inverted T-shaped sliding plate 46 can slide smoothly above the rotor 33.

[0029] Specifically, through the above technical solution, the first L-shaped plate 31 and the second L-shaped plate 32 are symmetrically fixed on both sides of the top surface of the support frame 3 to form a symmetrical guide structure. The inverted T-shaped sliding plate 46 at the bottom of the loading plate 4 is embedded between the two L-shaped plates. The stable connection is achieved by the engagement between the bottom of the inverted T-shaped plate and the upper part of the L-shaped plate, which effectively reduces the shaking during sliding. In addition, the rotor 33 assists the inverted T-shaped sliding plate 46 to slide smoothly, reduce frictional resistance, and improve the smoothness of movement.

[0030] Example 4: In this example, refer to Figure 4 and Figure 5 As shown, specifically, a guide opening 452 is provided below the positioning groove 451. The inner wall of the guide opening 452 is inclined, and the spacing between adjacent guide openings 452 is small, which facilitates the insertion of the guide plate 53 into the inner side of the positioning groove 451.

[0031] Specifically, the guide port 452 is located below the positioning groove 451, and the inner wall adopts an inclined design to form a funnel-shaped inlet, which effectively reduces the insertion resistance of the insert plate 53 and avoids misalignment or jamming. The small spacing between adjacent guide ports 452 ensures that the insert plate 53 maintains continuous and stable guidance during the insertion process, thereby improving assembly accuracy.

[0032] Working principle: When the operator performs hardness testing on the workpiece, firstly, according to the shape and size of the workpiece, adjust the position and table type of the support plate 4 below the testing end 11. For example, the first panel 41 of the support plate 4 can be moved below the testing end 11, and the workpiece can be placed on the first panel 41 for testing (during testing, follow the conventional hardness tester operation method, and simply move the testing end 11 down and press it onto the workpiece). The silicone pad on the first panel 41 can increase the friction of the workpiece and improve the testing stability.

[0033] When adjusting the carrier plate 4, the operator can slide the adjusting plate 5 inside the lower support frame 3 down along the guide post 35, so that the insert plate 53 in the middle of the adjusting plate 5 can disengage from the positioning groove 451 at the bottom of the carrier plate 4, thereby allowing the carrier plate 4 to slide flexibly left and right. After sliding until the first panel 41 is below the detection end 11, the operator releases the adjusting plate 5, which moves upward again under the elastic support of the spring 52. The insert plate 53 can be inserted into the positioning groove 451 at different positions to quickly lock the carrier plate 4, so that it can stably support the workpiece for detection. The multifunctional carrier plate 4 can be used for workpieces of different sizes and shapes, and has a wide range of applications.
