[0002] In metallographic inspection, it is necessary to preprocess the specimen, including grinding, polishing, corrosion, etc. When the thickness of the specimen is small and it is not convenient to hold, inlay treatment is often required before grinding and polishing. The inlay of the specimen takes a long time and affects the inspection efficiency. For the grinding and polishing of metallographic specimens with different shapes and sizes above 1 mm in thickness, there is a lack of special clamping tooling, which is not convenient for grinding and polishing operations. Content of the Utility Model
[0003] In view of the defects of the prior art, the utility model provides an auxiliary tooling for grinding and polishing a metallographic specimen, which can improve the clamping efficiency and has a large size range of adsorbed metallographic specimens.
[0004] In order to achieve the above purpose, the technical solution provided by the utility model is an auxiliary tooling for grinding and polishing a metallographic specimen, which includes a tooling main body, a specimen clip and a magnet insert. The tooling main body is provided with an adsorption surface, and a receiving groove is opened on the adsorption surface. A slot is opened on the tooling main body; the specimen clip is installed in the receiving groove, and the specimen clip is used for limiting the metallographic specimen; at least part of the magnet insert is inserted into the slot so that the adsorption surface can magnetically adsorb the metallographic specimen.
[0005] Further, a spirit level is arranged on the tooling main body.
[0006] Further, the magnet insert includes an insertion part, and when the magnet insert is inserted into the slot, the insertion part is accommodated inside the slot.
[0007] Further, the magnet insert includes a semi-circular ring part, and the semi-circular ring part is used to provide a pushing and pulling position for pushing the insertion part into or out of the slot.
[0008] Further, the insertion part and the semi-circular ring part are integrally formed.
[0009] Further, the specimen clip has an isosceles triangle frame structure, and serrated protrusions are respectively arranged on both sides of the inner edge of the isosceles triangle frame structure, and the serrated protrusions on both sides are used to limit the metallographic specimen.
[0010] Further, the receiving groove is isosceles triangle-shaped to cooperate with the specimen clip.
[0011] Further, the specimen clip is installed in the receiving groove with a slight interference fit.
[0012] Further, holding grooves are respectively formed on both sides of the tooling main body.
[0013] Further, the accommodating groove is close to and parallel to the adsorption surface.
[0014] During use, select a magnet insert with an appropriate magnetic field strength and insert it into the tooling main body (the magnetic strength only needs to ensure that the specimen can be adsorbed on the adsorption surface of the tooling main body, and there is no need to strongly fix the metallographic specimen so that it cannot move horizontally). Insert the specimen clip into the accommodating groove of the tooling main body, then place the specimen to be ground and polished into the area of the red circle in the above figure, and push the metallographic specimen towards the position near the pointed end of the specimen clip until it reaches the limit position.
[0015] Place the tooling main body with the metallographic specimen on a grinding and polishing machine such as a grinding wheel or a polishing machine for grinding and polishing operations. At the beginning, the metallographic specimen continues to move towards the position near the pointed end of the specimen clip under the action of frictional force and is finally fixed by the specimen clip. During the grinding and polishing process, adjust the horizontal angle through the spirit level on the tooling main body to ensure that the specimen surface is flat.
[0016] After grinding and polishing, pull out the magnet insert and take out the metallographic specimen.
[0017] The specimen clip and the tooling main body adopt a separated design. After the specimen clip ages or deforms, it can be directly replaced without replacing the whole.
[0018] The beneficial effects of the present utility model are as follows: A slot is formed on the tooling main body, and a magnet insert can be inserted into the slot. Select an appropriate magnet insert according to the weight of the metallographic specimen. The magnetic strength only needs to ensure that the metallographic specimen can be adsorbed on the adsorption surface of the tooling main body, and there is no need to strongly fix the metallographic specimen. When the thickness of the specimen is small, the metallographic specimen is adsorbed on the tooling main body without the need for embedding treatment, which can improve the clamping efficiency, and the size range of the adsorbed metallographic specimen is relatively large.

[0033] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model is made with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0034] Refer to Figures 1-6 , which shows the structural schematic diagram of an auxiliary tooling for grinding and polishing a metallographic specimen in an embodiment of the present utility model. It includes a tooling main body 100, a specimen clip 200 and a magnet insert 300. The tooling main body 100 is provided with an adsorption surface 110, and an accommodation groove 111 is formed on the adsorption surface 110. A slot 120 is formed on the tooling main body 100; the specimen clip 200 is installed in the accommodation groove 111, and the specimen clip 200 is used for limiting the metallographic specimen 10; at least a part of the magnet insert 300 is inserted into the slot 120 so that the adsorption surface 110 can magnetically adsorb the metallographic specimen 10.
[0035] On the tooling main body 100 of the above-mentioned auxiliary tooling for grinding and polishing a metallographic specimen, a slot 120 is provided. A magnet insert 300 can be inserted into the interior of the slot 120. Select a suitable magnet insert 300 according to the weight of the metallographic specimen 10. The magnetic strength only needs to ensure that the metallographic specimen 10 can be adsorbed on the adsorption surface 110 of the tooling main body 100, and there is no need to firmly fix the metallographic specimen 10. When the thickness of the specimen is small, the metallographic specimen 10 is adsorbed on the tooling main body 100 without the need for embedding treatment, which can improve the clamping efficiency, and the size range of the adsorbed metallographic specimen 10 is relatively large.
[0036] See Figure 7 , in one embodiment, a level 130 is provided on the tooling main body 100. With this setting, during the grinding and polishing process, the level 130 provided on the tooling main body 100 is used to adjust the horizontal angle of the tooling main body 100, thereby ensuring the horizontal angle of the metallographic specimen 10 adsorbed thereon and ensuring the flatness of the processed specimen surface. Specifically, the tooling main body 100 is made of plastic material.
[0037] See Figure 9 , in one embodiment, the magnet insert 300 includes an insertion portion 310. When the magnet insert 300 is inserted into the slot 120, the insertion portion 310 is accommodated inside the slot 120.
[0038] Continue to see Figure 9 , in one embodiment, the magnet insert 300 includes a semi-circular ring portion 320. The semi-circular ring portion 320 is used to provide a pushing and pulling position for pushing the insertion portion 310 into or out of the slot 120. When installing the magnet insert 300, the operator can hold the semi-circular ring portion 320 and push the insertion portion 310 into the slot 120 or pull out the insertion portion 310 outside the slot 120, which is convenient for installation and disassembly and further improves the operation efficiency.
[0039] In one embodiment, the insertion portion 310 and the semi-circular ring portion 320 are integrally formed. It should be noted that in other embodiments, the semi-circular ring portion 320 can also be set to other shapes as long as it is convenient for applying force.
[0040] See Figure 8 , in one embodiment, the specimen clip 200 has an isosceles triangle frame structure. Serrated protrusions 210 are respectively provided on both sides of the inner edge of the isosceles triangle frame structure. The serrated protrusions 210 on both sides are used to limit the metallographic specimen 10. Correspondingly, in this embodiment, the accommodation groove 111 is isosceles triangle-shaped to cooperate with the specimen clip 200. Specifically, the specimen clip 200 is slightly press-fitted into the accommodation groove 111. Specifically, the specimen clip 200 is made of a plastic material with a certain elasticity.
[0041] It should be noted that the specimen clip 200 is set in an isosceles triangle frame structure, and serrated protrusions 210 are provided on the inner side. The serrated protrusions 210 on both sides gradually approach from the side to the apex angle direction, which can adapt to metallographic specimens 10 of different sizes, and there is no requirement for the placement direction of the metallographic specimens 10.
[0042] Continue to refer to Figure 7 , in one embodiment, holding grooves 140 are respectively formed on both sides of the tooling main body 100.
[0043] In one embodiment, the accommodating groove 111 is close to and parallel to the adsorption surface 110.
[0044] Refer to Figure 3 and Figure 4 , during use, a magnet insert 300 with an appropriate magnetic field strength is selected and inserted into the slot 120 of the tooling main body 100. The magnetic strength only needs to ensure that the specimen can be adsorbed on the adsorption surface 110 of the tooling main body 100, and there is no need to strongly fix the metallographic specimen 10 so that it cannot move horizontally. The specimen clip 200 is inserted into the accommodating groove 111 of the tooling main body 100, and then the specimen to be ground and polished is placed in the area in the middle of the specimen clip 200. Push the metallographic specimen 10 towards the position near the pointed end of the specimen clip 200 until it reaches the limit position. It should be noted that Figure 3 and Figure 4 show that the metallographic specimen 10 is square. In specific applications, the metallographic specimen 10 can be of any shape, and there is no limit to the adsorption form of the metallographic specimen 10. As long as the metallographic specimen 10 is pushed to the limit position, the serrated protrusions 210 on both sides of the specimen clip 200 can clamp the specimen clip 200 to a certain extent.
[0045] Place the tooling main body 100 with the metallographic specimen 10 on a grinding machine or a polishing machine for grinding and polishing operations. At the beginning, the metallographic specimen 10 continues to move towards the position near the pointed end of the tooling main body 100 under the action of friction, and finally is fixed by the tooling main body 100. During the grinding and polishing process, adjust the horizontal angle through the level on the tooling main body 100 to ensure that the specimen surface is flat.
[0046] After grinding and polishing, pull out the magnet insert 300 and take out the metallographic specimen 10.
[0047] The specimen clip 200 and the tooling main body 100 are designed to be separated. After the specimen clip 200 ages or deforms, the specimen clip 200 can be directly replaced without replacing the whole, saving costs.
