[0002] In the research and development of new materials, metallographic sample analysis is an important means. For example, when developing new aluminum alloys, metallographic samples are prepared, their metallographic structure (such as grain size, phase distribution, etc.) is observed, and the effects of the addition of different alloying elements on the aluminum alloy structure are studied. Then, the alloy composition is optimized to obtain new materials with specific properties (such as high strength, good corrosion resistance, etc.). During the research and development process, a fixture is needed to fix and cut it to facilitate subsequent testing and preparation.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Reference Figure 1-Figure 3 The utility model provides an embodiment of a clamp for cutting metallographic specimens, comprising a clamping frame 1, the inner wall of which is penetrated by a fastening bolt 2 and threadedly connected thereto, the inner wall of the clamping frame 1 is provided with a pattern corresponding to the fastening bolt 2, which allows the fastening bolt 2 to move vertically along its inner wall, a plug-in plate 3 is plugged into the bottom end of the fastening bolt 2, the plug-in plate 3 can be replaced and can adapt to metallographic specimens of different diameters, a limiting groove 7 is provided on the inner wall of the fastening bolt 2, and a limiting mechanism is provided on the inner wall of the plug-in plate 3;
[0026] The limiting mechanism includes a pressing block 5, which can move the limiting block 6 laterally by pressing the pressing block 5. The left end of the pressing block 5 is fixedly connected to the limiting block 6. The limiting block 6 is inclined. When the inclined surface is squeezed, the limiting block 6 will slide along the inner wall of the plugboard 3. The right end of the pressing block 5 is elastically connected to the plugboard 3 through an elastic component. The pressing block 5 passes through and is slidably connected to the inner wall of the plugboard 3. A notch corresponding to the pressing block 5 is provided on the plugboard 3, so that the pressing block 5 can move along the notch. The limiting block 6 passes through and is slidably connected to the inner wall of the plugboard 3.
[0027] The elastic component includes a return spring 4, one end of which is fixedly connected to the right end of the pressing block 5. When the pressing block 5 moves to the right, the return spring 4 is compressed. When resetting, the pressing block 5 is reset by the elastic force of the return spring 4. The other end of the return spring 4 is fixedly connected to the inner wall of the right end of the inserting plate 3. The limit block 6 is inserted into the inner wall of the limit groove 7. Two groups of fastening bolts 2 are provided. The two groups of fastening bolts 2 are vertically distributed on the inner wall of the clamping frame 1, and the surface of the fastening bolts 2 is threaded.
[0028] Working principle: First, when you need to clamp and cut the metallographic sample, just place the metallographic sample between two sets of fastening bolts 2, then twist the fastening bolts 2 to make the fastening bolts 2 move downward with the insert plate 3 to contact and squeeze the fixed metallographic sample. After the fixation is completed, use the cutting knife to cut the fixed metallographic sample.
[0029] When it is necessary to replace the inserting plate 3 according to the metallographic specimen of different shapes, it is only necessary to press the pressing block 5 to separate the limit block 6 and the limit groove 7, and then separate the inserting plate 3 from the inner wall of the fastening bolt 2. When it is necessary to install the inserting plate 3 of the corresponding shape, it is only necessary to insert the inserting plate 3 into the bottom end of the fastening bolt 2, which will allow the bottom end of the fastening bolt 2 to squeeze the inclined surface of the limit block 6, allowing the limit block 6 to move the pressing block 5 to the right and allow the limit block 6 to enter the inserting plate 3. When the limit block 6 and the inner wall of the limit groove 7 coincide with each other, the reverse elastic force of the reset spring 4 is used to reset the limit block 6 and the pressing block 5, so that the limit block 6 is plugged into the notch of the limit groove 7 to complete the one-way limit of the inserting plate 3.
[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
