Description

Technical Field

[0001] This utility model relates to the field of abrasive technology, and more specifically, to a diamond composite louvered abrasive. Background Technology

[0002] Diamond composite louvered abrasive discs, also known as diamond louvered grinding discs or diamond soft grinding discs, use diamond as the abrasive and can be used to process irregular shapes of materials such as ceramics, stone, glass, and floor tiles. They can also be used for grinding marble floors, concrete floors, cement floors, terrazzo floors, microcrystalline glass, floor tiles, as well as for the repair and renovation of flooring.

[0003] After searching, it was found that application number CN202320356350.6, entitled "A Diamond Composite Louvered Abrasive Tool," utilizes spaced silicon carbide blocks and diamond blocks for heat dissipation and sound-absorbing cotton to reduce noise. However, in actual use, especially during grinding, water spraying is generally used for cooling, which is faster and more effective. Meanwhile, during grinding, noise spreads widely, making it difficult for the sound-absorbing cotton to provide adequate noise reduction, thus reducing noise and increasing operational instability. Furthermore, different grit sizes of grinding discs are typically used, usually with a smaller grit for initial grinding followed by a larger grit for fine grinding. At least two sets of grinding discs need to be used interchangeably. To save on equipment investment, workers often need to change the grinding discs frequently, which is inconvenient and affects work efficiency. Further improvements are needed.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a diamond composite louvered abrasive disc, which has the advantages of convenient switching and reduced equipment usage, thereby solving the problems mentioned in the background technology.

[0006] To achieve the advantages of convenient switching and reduced equipment usage, the specific technical solution adopted by this utility model is as follows: A diamond composite louvered abrasive tool includes an inner substrate and an outer substrate. An inner diamond abrasive disc and an outer diamond abrasive disc are fixedly bonded to the bottom surfaces of the inner substrate and the outer substrate, respectively. A mounting base is integrally connected to the top surface of the inner substrate, and a side ring is integrally connected to the side wall of the mounting base. A handle bolt is threaded through the surface of the side ring, and the bottom surface of the handle bolt is rotatably connected to the top surface of the outer substrate.

[0007] Furthermore, a top seat is fixedly connected to the top surface of the outer substrate, and an inner plate is rotatably connected inside the top seat. The handle bolt passes through the top surface of the top seat and is fixedly connected to the top surface of the inner plate.

[0008] Furthermore, a guide groove is formed on the inner surface of the outer substrate, and a guide strip is formed on the outer surface of the inner substrate, with the guide strip passing through the guide groove and slidably connected to the guide groove.

[0009] Furthermore, a guide rod is fixedly installed on the top surface of the outer substrate, and the guide rod passes through the edge ring and is slidably connected to the edge ring.

[0010] Furthermore, the guide grooves and guide strips are distributed in multiple sets at equal angles along the central axis of the mounting base.

[0011] Furthermore, a mounting hole is provided at the center of the top surface of the mounting base, and bolt holes are provided on the outer side of the mounting hole on the top surface of the mounting base.

[0012] Furthermore, the inner diamond grinding discs are distributed in multiple sets at equal angles along the central axis of the inner substrate, and the inner diamond grinding discs are diamond composite louvers.

[0013] Furthermore, the outer diamond grinding discs are distributed in multiple sets at equal angles along the central axis of the outer substrate, and the outer diamond grinding discs are also diamond composite louvers, and the mesh count of the outer diamond grinding discs is different from that of the inner diamond grinding discs.

[0014] Compared with the prior art, this utility model provides a diamond composite louvered abrasive, which has the following beneficial effects: (1) This utility model adopts an inner substrate and an outer substrate. The bottom surfaces of the outer substrate and the inner substrate are respectively glued with an outer diamond grinding disc and an inner diamond grinding disc at equal angles. The grit number of the outer diamond grinding disc is different from that of the inner diamond grinding disc. When performing grinding work, the operator can fix the mounting base to the output end of the grinding machine. First, the outer diamond grinding disc is used for grinding. When it is necessary to switch the grinding grit, the operator can turn the handle bolt and pull the outer substrate upward, thereby moving the outer diamond grinding disc above the inner diamond grinding disc, so that the inner diamond grinding disc contacts the grinding surface, and the switching can be completed quickly. This eliminates the trouble of using two grinding machines, reduces the equipment investment, avoids the trouble of changing different grinding tools, and improves the convenience of use.

[0015] (2) This utility model adopts an inner substrate and an outer substrate. Both the inner substrate and the outer substrate are made of steel plates. The inner diamond grinding disc and the outer diamond grinding disc are firmly bonded to the inner substrate and the outer substrate respectively. The inner substrate and the outer substrate provide a stable mounting platform to avoid breakage and accidents. At the same time, when the inner diamond grinding disc and the outer diamond grinding disc are damaged, they can be replaced simply by soaking and degumming and then re-bonding the inner diamond grinding disc and the outer diamond grinding disc. This avoids the trouble of replacing the whole thing and reduces the amount of consumables used. Attached Figure Description

[0019] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0020] According to an embodiment of the present invention, a diamond composite louvered abrasive is provided.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Please refer to them. Figure 1 and Figure 4 According to an embodiment of the present invention, a diamond composite louvered abrasive tool includes an inner substrate 1 and an outer substrate 2. The outer substrate 2 has a circular structure and is made of 65Mn spring steel plate with a thickness of 2-3mm. It has good elasticity and wear resistance. The inner substrate 1 is also made of 65Mn spring steel plate. The bottom surfaces of the inner substrate 1 and the outer substrate 2 are respectively fixedly bonded with an inner diamond abrasive 3 and an outer diamond abrasive 4 by high-strength resin adhesive. The bonding strength is ≥5MPa to ensure that they will not fall off during grinding.

[0022] The inner substrate 1 has an integrally stamped mounting base 5 on its top surface. The mounting base 5 is a cylindrical structure with an inner diameter that matches the output shaft of the grinder. The side wall of the mounting base 5 is integrally connected to a side ring 9, which is a ring-shaped steel plate perpendicular to the mounting base 5. A handle bolt 10 is threaded through the surface of the side ring 9. The head of the handle bolt 10 has anti-slip textures for easy manual rotation. The bottom surface of the handle bolt 10 is rotatably connected to the top surface of the outer substrate 2 to ensure that the outer substrate 2 will not rotate when the handle bolt 10 is rotated.

[0023] The bottom surfaces of the outer substrate 2 and the inner substrate 1 are respectively attached with an outer diamond grinding disc 4 and an inner diamond grinding disc 3 at equal angles. The mesh count of the outer diamond grinding disc 4 is different from that of the inner diamond grinding disc 3 (for example, the outer disc is 80 mesh for coarse grinding and the inner disc is 320 mesh for fine grinding) to meet the needs of different grinding stages.

[0024] During grinding, the operator can fix the mounting base 5 to the output end of the grinding machine with bolts (using mounting holes 6 and bolt holes 7), start the grinding machine, and first use the outer diamond grinding disc 4 to contact the workpiece for rough grinding. When it is necessary to switch to fine grinding, the operator can manually turn the handle bolt 10. The handle bolt 10, through its thread engagement with the edge ring 9, pulls the outer base plate 2 upward, thereby moving the outer diamond grinding disc 4 above the inner diamond grinding disc 3. At this time, the inner diamond grinding disc 3 contacts the grinding surface, and the switch can be completed quickly. This eliminates the trouble of using two grinding machines, reduces equipment investment, and avoids the trouble of stopping the machine to change different grinding tools, thus improving the convenience of use and work efficiency.

[0025] Please refer to Figure 1 and Figure 3 The top surface of the outer substrate 2 is fixedly connected to the top seat 12 by welding. The top seat 12 is a hollow cylindrical structure, and the inner plate 13 is rotatably connected to the inside of the top seat 12 by bearings. The inner plate 13 is a circular steel plate. The handle bolt 10 passes through the top surface of the top seat 12 and is welded to the top surface of the inner plate 13. The top surface of the top seat 12 has a through hole for the handle bolt 10 to pass through, and the diameter of the through hole is larger than the outer diameter of the handle bolt 10 (gap 2-3mm) to ensure that the handle bolt 10 can rotate and move up and down freely. The handle bolt 10, the inner plate 13 and the top seat 12 are arranged coaxially. The inner plate 13 plays the role of rotational connection and axial limit. When the handle bolt 10 rotates, the inner plate 13 rotates with the handle bolt 10. At the same time, through the bearing connection with the top seat 12, the function of pulling the outer substrate 2 up and down is realized, avoiding jamming caused by the direct rigid connection between the handle bolt 10 and the outer substrate 2.

[0026] Please refer to Figure 1 and Figure 2The inner surface of the outer substrate 2 is provided with a guide groove 14, which is a rectangular groove. The outer surface of the inner substrate 1 is integrally formed with a guide strip 8. The cross-sectional dimensions of the guide strip 8 are adapted to those of the guide groove 14, and the guide strip 8 passes through the guide groove 14 and is slidably connected to the guide groove 14. The guide groove 14 and the guide strip 8 are distributed in multiple sets (usually 5-6 sets) at equal angles along the central axis of the mounting base 5. The guide groove 14 and the guide strip 8 form a sliding guide structure to prevent relative rotation between the inner substrate 1 and the outer substrate 2, and play a circumferential limiting role, ensuring that the inner substrate 1 and the outer substrate 2 rotate synchronously, improving the stability of rotation, and avoiding shaking during grinding that affects the accuracy.

[0027] Please refer to Figure 1 and Figure 4 A guide rod 11 is fixedly installed on the top surface of the outer substrate 2 by welding. The guide rod 11 is a round steel (8-10mm in diameter) and passes through the edge ring 9 and is slidably connected to the edge ring 9 (with a fit gap of 0.1-0.2mm). This provides precise guidance for the lifting and lowering of the outer substrate 2, ensuring that the outer substrate 2 lifts and lowers smoothly along the axial direction, avoiding uneven force on the grinding disc caused by tilting, and improving the stability of the lifting and lowering of the outer substrate 2.

[0028] Both the inner substrate 1 and the outer substrate 2 are made of high-strength steel plates, possessing sufficient rigidity and toughness. The inner diamond grinding disc 3 and the outer diamond grinding disc 4 are firmly bonded to the inner substrate 1 and the outer substrate 2 respectively using resin adhesive. The inner substrate 1 and the outer substrate 2 provide a stable mounting platform for the grinding discs, preventing breakage due to excessive force and potential safety accidents. Furthermore, when the inner diamond grinding disc 3 and the outer diamond grinding disc 4 become worn or damaged, the grinding wheel can be simply immersed in a desiccant (such as acetone) until the adhesive softens, the old grinding disc can be removed, the substrate surface cleaned, and new inner diamond grinding disc 3 and outer diamond grinding disc 4 can be re-bonded to complete the replacement. This avoids the hassle of replacing the entire grinding wheel, significantly reducing consumable usage and costs.

[0029] Please refer to Figure 1 and Figure 4 The mounting base 5 has a mounting hole 6 (fitted to the output shaft of the grinder) at the center of its top surface, and bolt holes 7 (usually 3-4) are evenly distributed on the outer side of the mounting hole 6 on the top surface of the mounting base 5. This is a common flange-type mounting structure, which facilitates quick connection and fixation with various types of grinding equipment.

[0030] Please refer to Figure 1 and Figure 2 Multiple sets of inner diamond grinding discs 3 are distributed at equal angles along the central axis of the inner substrate 1. The inner diamond grinding discs 3 are diamond composite louvers. The diamond composite louvers use a resin binder to solidify the abrasive (such as brown corundum) and diamond grinding particles on the glass fiber cloth substrate. They have the characteristics of high grinding efficiency and long service life, and are a common structure in this field.

[0031] Please refer to Figure 1 and Figure 2 Multiple sets of outer diamond grinding discs 4 are distributed at equal angles along the central axis of the outer substrate 2. The outer diamond grinding discs 4 are also diamond composite blades. The mesh count of the outer diamond grinding discs 4 is different from that of the inner diamond grinding discs 3 (e.g., 80-120 mesh for the outer discs and 240-400 mesh for the inner discs). Workers can select the appropriate combination of diamond composite blades with different mesh counts according to the hardness and surface requirements of the grinding material (such as metal, stone, ceramic) to improve the grinding quality.

[0032] Working principle: When in use, the grinding wheel is fixedly connected to the output end of the grinder through the mounting holes 6 and bolt holes 7 of the mounting base 5 to ensure a secure installation.

[0033] In the initial state, the outer substrate 2 is in a low position, and the outer diamond grinding disc 4 is lower than the inner diamond grinding disc 3. Start the grinder, hold the grinder and make the outer diamond grinding disc 4 contact the workpiece to be ground, and use its coarse mesh characteristics to perform a rough grinding operation to quickly remove material.

[0034] When fine polishing is required to obtain a smooth surface, stop the polisher or keep it running at a low speed. The handle bolt 10 is pulled upward by the thread of the side ring 9, which drives the outer base plate 2 to slide upward along the guide groove 14 and the guide bar 8 through the top seat 12 and the inner plate 13. The guide rod 11 slides and guides along the side ring 9 at the same time to ensure that the outer base plate 2 rises horizontally.

[0035] Until the outer diamond grinding disc 4 is completely raised above the inner diamond grinding disc 3, at which point the inner diamond grinding disc 3 is exposed and lower than the outer diamond grinding disc 4, start the grinding machine so that the inner diamond grinding disc 3 contacts the workpiece and uses its fine grit number characteristics for fine grinding.

[0036] During the polishing process, the cooperation between the guide bar 8 and the guide groove 14 ensures that the inner and outer substrates rotate synchronously, avoiding uneven polishing marks caused by relative rotation.

[0037] When the grinding discs are worn and need to be replaced, soak the grinding wheel in a degumming agent to remove the old grinding discs. After cleaning the substrate surface, attach the new inner and outer diamond grinding discs in their original positions. After curing, they can be reused.

[0038] This grinding wheel allows for quick switching between two different grit sizes via a liftable outer base plate, simplifying the grinding process, improving work efficiency, and reducing equipment investment and consumable costs. It is suitable for grinding various materials.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
