Description

Technical Field

[0001] This utility model relates to the field of hardness testing technology, specifically to a positioning device for testing the hardness of metallic materials. Background Technology

[0002] Hardness testing of metallic materials refers to a physical property testing technique that uses specific testing equipment and standard testing methods to apply pressure to the surface of a metallic material with an indenter of a specified shape, and then quantitatively evaluates the material's ability to resist local deformation based on the size of the indentation. It can not only quickly reflect the hardness of a metallic material, but also indirectly infer key mechanical properties such as strength, wear resistance, and toughness. It is one of the most commonly used and convenient testing methods for evaluating the performance of metallic materials.

[0003] When testing the hardness of metallic materials, the key to positioning is to ensure that the test area meets the test requirements and that the data is accurate and representative. On the one hand, it is necessary to avoid defects, edges, and areas with uneven heat treatment on the material surface, so as to avoid these factors interfering with the formation of indentations and causing the test results to deviate from the true hardness of the material.

[0004] However, when positioning metal materials, some metal materials have irregular edges and irregular shapes, making positioning difficult. Therefore, a metal material hardness testing and positioning device is proposed to solve the above-mentioned problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 The metal material hardness testing and positioning device in this embodiment includes a measuring component 1, a connecting component 2, and a positioning component 3. The connecting component 2 is connected to the measuring component 1, and the positioning component 3 is connected to the connecting component 2.

[0019] It is understandable that by adjusting the positioning component 3 and the connecting component 2, the metal materials of different shapes can be positioned and stabilized.

[0020] The measuring component 1 includes a base 101, a cantilever 102, and a pressure head 103. The connecting component 2 is fixed to the base 101. A lifting platform is provided inside the base 101. A handwheel is rotatably connected to the bottom of the base 101. The lifting platform is moved up and down by the handwheel. The cantilever 102 is fixed to the top of the base 101. The pressure head 103 is connected to the bottom of the cantilever 102.

[0021] It should be noted that by setting up the handwheel and the lifting platform, turning the handwheel will drive the lifting platform to rise, which will facilitate the contact between the metal material and the pressure head 103, and facilitate the device to detect the hardness of the material.

[0022] Please see Figure 2 To improve the stability of material positioning, the connecting component 2 in this embodiment includes a base plate 201, a sliding plate 202, a connecting plate 203, and a threaded rod 204. The base plate 201 is fixed to the top of the lifting platform, and the sliding plate 202 is movably connected to the top of the base plate 201. The top of the base plate 201 is provided with a movable groove, and the sliding plate 202 is slidably connected to the base plate 201 through the movable groove.

[0023] It can be observed that the setting of the movable groove facilitates the stable sliding of the sliding plate 202, which in turn facilitates the pressing of the connecting plate 301 against the top support spring 305, thereby improving the stability of the material and enhancing the performance of the device.

[0024] The top of the base plate 201 is provided with a limiting groove that communicates with the movable groove. The connecting plate 203 is slidably connected to the base plate 201 through the limiting groove. The sliding plate 202 is provided in two sets, left and right, with two in each set. Each set of sliding plates 202 is fixed to the connecting plate 203. The threaded rod 204 is rotatably connected to the base plate 201.

[0025] It is not difficult to see that the setting of the limiting groove is conducive to the stable setting of the connecting plate 203. The connection between the connecting plate 203 and the sliding plate 202 is conducive to the stable displacement of the sliding plate 202 by rotating the threaded rod 204, thereby improving the positioning stability.

[0026] The connecting plate 203 is threadedly connected to the threaded rod 204. The left side of the threaded rod 204 passes through the base plate 201. An adjustment knob is fixed on the left side of the threaded rod 204. The positioning component 3 is controlled by the adjustment knob. Two sections of threaded wire with opposite directions are fixed on the threaded rod 204.

[0027] It should also be noted that the ventilation adjustment knob increases the outer surface of the threaded rod 204, which improves the ease of rotation of the threaded rod 204 and enhances the effectiveness of the device. Rotating the threaded rod 204 in the opposite direction facilitates the relative or opposite displacement of the connecting plate 203, which is beneficial for adjusting the tightness of the material.

[0028] Please see Figure 3 In order to achieve the positioning of materials, the positioning component 3 in this embodiment includes a connecting plate 301, a movable column 302, a baffle 303, a fixed plate 304, a top support spring 305, and a linkage plate 306. The connecting plate 301 is movably connected to the connecting component 2. Multiple movable columns 302 are provided, and multiple movable columns 302 are slidably connected in the connecting plate 301.

[0029] In actual use, the setting of multiple movable columns 302 is conducive to achieving multi-point contact with the material, which in turn facilitates the positioning of materials with different shapes, improves the positioning effect of the device, and enhances the overall performance of the device.

[0030] A sliding channel is provided on the connecting plate 301, and the movable column 302 is slidably connected to the connecting plate 301 through the sliding channel. The baffle 303 is fixed at the end of the movable column 302 near the connecting plate 301.

[0031] In actual setup, the sliding channel facilitates the stable sliding of the movable column 302, thereby enabling stable positioning of the material and improving the stability of the device.

[0032] The fixed plate 304 is fixed to the outside of the movable column 302, the top support spring 305 is fixed between the fixed plate 304 and the connecting plate 301, and the top support spring 305 is wrapped around the outside of the movable column 302. The linkage plate 306 is slidably connected to multiple movable columns 302.

[0033] It should be noted that the support spring 305 helps to support the movable column 302, which in turn helps to resist the material through the movable column 302, thus facilitating the positioning function of the material.

[0034] The working principle of the above embodiments is as follows: Pulling the linkage plate 306 on one side places the metal material between the two sets of movable columns 302 on the left and right. The top support spring 305 supports the fixed plate 304, thereby causing the movable columns 302 to contact the metal material. By setting multiple movable columns 302, multiple points of the metal material are contacted, thus achieving the positioning of the irregularly shaped metal block. At the same time, by rotating the threaded rod 204, under the action of the opposite thread, the movable columns 302 on both sides are moved relative to each other, thereby further compressing the top support springs 305 on both sides, thus further stabilizing the measured metal material. By shaking the handwheel, the base plate 201 is raised, thereby allowing the pressure head 103 to contact the metal material, realizing the detection of the material hardness. The whole device is easy to use, can be adapted to materials of different shapes, and has a good positioning effect.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
