Description

Technical Field

[0001] This utility model relates to the field of composite diamond flaps, and more particularly to composite diamond flaps for use in abrasives. Background Technology

[0002] The existing diamond flap wheel consists of several grinding discs and a substrate. Each grinding disc is glued to the substrate, and the working layer and the bottom layer of the grinding disc are bonded together in a 1:1 ratio.

[0003] When the flap wheel is rotating at high speed, heat can easily be transferred from the grinding disc to the substrate covered by the working layer. The adhesive is easily heated, which reduces its bonding performance and reduces the substrate's holding force on the grinding disc. As a result, the grinding disc is poorly fixed and there is a risk that it may fall off and be thrown out.

[0004] Therefore, it is necessary to provide composite diamond flaps for abrasives to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a composite diamond flap for abrasives, which solves the problems in the prior art.

[0006] To solve the aforementioned technical problems, this utility model provides a composite diamond flap for abrasives, including a connecting seat. A fixing seat is mounted on the top surface of the connecting seat. A slanted groove is formed at the edge of the top surface of the fixing seat. The flap body is engaged inside the slanted groove, and adhesive is applied inside the slanted groove. This structure upgrades the traditional single adhesive fixing to a dual fixing mode of "slanted groove engagement + adhesive bonding". The presence of the slanted groove increases the contact area between the flap body and the fixing seat, forming a mechanical limit. Even if the adhesive degrades due to the heat generated by high-speed rotation, the slanted groove can still restrict the movement of the flap body by its physical structure, preventing it from falling off and being thrown out. This greatly improves the safety and stability of the flap wheel during operation, ensuring the safety of equipment operation and operators.

[0007] Selectedly, the top surface of the fixing seat has a countersunk hole above the inclined groove. A screw is inserted into the countersunk hole, and the bottom end of the screw extends through the bottom surface of the fixing seat to the outside of the fixing seat. A nut is screwed onto the outer surface of the screw, and a limiting plate is provided at the top of the screw. The countersunk hole above the inclined groove of the fixing seat, together with the screw, nut, and limiting plate, constitute a fastening and strengthening structure. When the nut is tightened, the tension generated by the screw is evenly applied to the louver body through the limiting plate, making it fit tightly against the fixing seat, forming a triple fixing effect with the inclined groove and adhesive bonding. This structure significantly enhances the holding force of the substrate on the louver body, enabling the louver body to withstand greater centrifugal force and grinding force under high-speed rotation conditions, reducing the risk of loosening and falling off, extending the service life of the louver wheel, and reducing equipment maintenance costs and safety hazards.

[0008] Selectedly, the surface of the louver body is provided with a through hole, the inner diameter of which is equal to the outer diameter of the screw. The through hole on the surface of the louver body is equal to the diameter of the screw. This through hole design allows the screw to accurately penetrate the louver body and cooperate with the countersunk hole on the fixing seat. This ensures that when the screw applies a tightening force, it can fix the louver body evenly and stably on the fixing seat, avoiding deformation or damage to the louver body due to uneven force. This ensures the reliability and stability of the overall structure of the louver wheel, thereby guaranteeing the grinding accuracy.

[0009] The outer diameter of the limiting plate is equal to the inner diameter of the countersunk hole. This size-matching design allows the limiting plate to be fully embedded in the countersunk hole. When the screw is tightened, the limiting plate fits tightly against the wall of the countersunk hole, preventing the screw from shifting or shaking during rotation. This ensures that the tightening force is evenly transmitted to the louver body, further enhancing the fixing effect. At the same time, it makes the louver wheel look flatter and reduces the risk of interference caused by protrusions.

[0010] The thickness of the inclined groove is equal to the thickness of the louver body, ensuring that the louver body can be precisely and tightly embedded in the inclined groove, forming a seamless snap-fit. This precise dimensional matching not only fully utilizes the mechanical limiting function of the inclined groove but also ensures that the louver body is subjected to uniform force on the fixed base. This avoids wobbling of the louver body during rotation due to excessive gaps, or installation difficulties and component damage due to insufficient gaps, thereby improving the operational stability and processing quality of the flap wheel.

[0011] Optionally, multiple inclined slots are provided, and these slots are equidistantly arranged around the top surface of the fixed base. This arrangement ensures that the louver blades are evenly distributed on the fixed base, guaranteeing balanced forces during rotation, reducing vibrations caused by center-of-gravity shifts, and improving the rotational accuracy and stability of the louver wheel. Furthermore, this layout allows for flexible adjustment of the number and installation position of the louver blades according to actual grinding requirements, enhancing the louver wheel's applicability and meeting the requirements of different processing scenarios.

[0012] Selectedly, multiple heat dissipation holes are provided, and these holes are equidistantly located on the surface of the connecting seat. The presence of multiple equidistant heat dissipation holes on the surface of the connecting seat enables the heat generated during grinding to be quickly dissipated when the flap wheel rotates at high speed. This reduces the temperature of the connecting seat, the fixed seat, and the main body of the flap, preventing problems such as decreased adhesive performance and weakened component material performance caused by high temperatures. It effectively protects the structural strength and connection performance of each component, ensuring that the flap wheel can maintain efficient and stable operation even under long-term continuous operation.

[0013] Compared with related technologies, the composite diamond flaps for abrasives provided by this utility model have the following advantages: Compared to existing technologies, this design, by creating a slanted groove at the edge of the top surface of the mounting base and engaging the louver body within the groove while applying adhesive, increases the contact area between the louver body and the mounting base, resulting in a more secure connection. The slanted groove also provides a certain degree of restraint on the louver body; even if the high-speed rotation of the flap wheel generates heat that reduces the adhesive bonding performance, the groove's structure effectively prevents the louver body from detaching or being thrown out, thus improving the safety and stability of the flap wheel during operation.

[0014] Compared to existing technologies, this design features a countersunk hole on the top surface of the mounting base above the inclined groove. A screw is inserted into this countersunk hole, with its bottom end extending through the bottom surface of the mounting base to the outside. A nut is screwed onto the outer surface of the screw, and a limiting disc is positioned at the top of the screw. This structure further enhances the connection strength between the louver body and the mounting base. When the nut is tightened, the screw presses the louver body firmly against the mounting base. Combined with the locking action of the inclined groove, this creates a double-fixing effect, significantly improving the base's holding force on the louver body. This ensures that the louver body will not loosen or fall off during high-speed rotation, extending the service life of the louver wheel and reducing safety hazards during use.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please refer to the following: Figure 1-5 A composite diamond flap for abrasives includes a connecting seat 1, a fixing seat 4 mounted on the top surface of the connecting seat 1, and a slanted groove 5 formed at the edge of the top surface of the fixing seat 4. The flap body 2 is engaged within the slanted groove 5, which is coated with adhesive. This structure upgrades the traditional single adhesive fixing to a dual fixing mode of "slanted groove 5 engagement + adhesive bonding." The presence of the slanted groove 5 increases the contact area between the flap body 2 and the fixing seat 4, forming a mechanical limit. Even if the adhesive performance deteriorates due to the heat generated by high-speed rotation, the slanted groove 5 can still restrict the movement of the flap body 2 through its physical structure, preventing it from falling off and being thrown out. This greatly improves the safety and stability of the flap wheel during operation, ensuring the safety of equipment operation and operators.

[0020] Example 2, see Figure 1-5The top surface of the fixing base 4 has a countersunk hole 6 above the inclined groove 5. A screw 8 is inserted into the countersunk hole 6, and the bottom end of the screw 8 extends through the bottom surface of the fixing base 4 to the outside of the fixing base 4. A nut 9 is screwed to the outer surface of the screw 8. A limiting plate 7 is provided at the top of the screw 8. The countersunk hole 6 above the inclined groove 5 of the fixing base 4, together with the screw 8, nut 9 and limiting plate 7, constitute a fastening and strengthening structure. When the nut 9 is tightened, the tension generated by the screw 8 is evenly applied to the louver body 2 through the limiting plate 7, making it fit tightly against the fixing base 4, and forming a triple fixing effect with the inclined groove 5 and adhesive bonding. This structure significantly enhances the holding force of the substrate on the louver body 2, enabling the louver body 2 to withstand greater centrifugal force and grinding force under high-speed rotation conditions, reducing the risk of loosening and falling off, extending the service life of the louver wheel, and reducing equipment maintenance costs and safety hazards.

[0021] Example 3, see Figure 1-5 The louver body 2 has a through hole on its surface. The inner diameter of the through hole is equal to the outer diameter of the screw 8. The through hole on the surface of the louver body 2 has a diameter equal to that of the screw 8. This through hole design allows the screw 8 to accurately penetrate the louver body 2 and cooperate with the countersunk hole 6 on the fixing seat 4. This ensures that when the screw 8 applies a tightening force, it can evenly and stably fix the louver body 2 on the fixing seat 4, avoiding deformation or damage to the louver body 2 due to uneven force. This ensures the reliability and stability of the overall structure of the louver wheel, thereby guaranteeing the grinding accuracy.

[0022] Example 4, see Figure 1-5 The outer diameter of the limiting plate 7 is equal to the inner diameter of the countersunk hole 6. This size adaptation design allows the limiting plate 7 to be fully embedded in the countersunk hole 6. When the screw 8 is tightened, the limiting plate 7 fits tightly against the wall of the countersunk hole 6, preventing the screw 8 from shifting or shaking during rotation. This ensures that the tightening force is evenly transmitted to the louver body 2, further enhancing the fixing effect. At the same time, it makes the louver wheel appearance flatter and reduces the risk of interference caused by protrusions.

[0023] Example 5, see Figure 1-5 The internal thickness of the inclined groove 5 is equal to the thickness of the louver body 2, ensuring that the louver body 2 can be precisely and tightly embedded in the inclined groove 5, forming a seamless snap-fit. This precise dimensional matching not only fully utilizes the mechanical limiting function of the inclined groove 5, but also ensures that the louver body 2 is subjected to uniform force on the fixed base 4, avoiding wobbling of the louver body 2 during rotation due to excessive gaps, or installation difficulties and component damage due to insufficient gaps, thereby improving the operational stability and processing quality of the flap wheel.

[0024] Example 6, see Figure 1-5 Multiple inclined grooves 5 are provided, and these grooves 5 are equidistantly arranged around the top surface of the fixed base 4. This arrangement ensures that the flap bodies 2 are evenly distributed on the fixed base 4, guaranteeing force balance during flap wheel rotation, reducing vibration caused by center of gravity shift, and improving the rotational accuracy and stability of the flap wheel. Furthermore, this layout allows for flexible adjustment of the number and installation position of the flap bodies 2 according to actual grinding requirements, enhancing the applicability of the flap wheel and meeting the requirements of different processing scenarios.

[0025] Example 7, see Figure 1-5 Multiple heat dissipation holes 3 are provided, and the multiple heat dissipation holes 3 are equally spaced on the surface of the connecting seat 1. The multiple equally spaced heat dissipation holes 3 on the surface of the connecting seat 1 can quickly dissipate the heat generated by grinding when the louver wheel is rotating at high speed, reduce the temperature of the connecting seat 1, the fixed seat 4 and the louver body 2, avoid problems such as the degradation of adhesive performance and the weakening of component material performance due to high temperature, effectively protect the structural strength and connection performance of each component, and ensure that the louver wheel can still maintain efficient and stable operation under long-term continuous working conditions.

[0026] The working principle of the composite diamond flap for grinding wheels provided by this utility model is as follows: When installing the composite diamond louver for the abrasive, firstly, the connecting seat 1 is connected and fixed to the abrasive equipment. Multiple equidistant heat dissipation holes 3 on the surface of the connecting seat 1 help dissipate heat quickly during operation, preventing heat buildup from affecting the performance of various components. Next, the louver body 2 is inserted into the inclined groove 5 at the edge of the top surface of the fixing seat 4. Since the internal thickness of the inclined groove 5 is equal to the thickness of the louver body 2, and multiple inclined grooves 5 are equally spaced around the top surface of the fixing seat 4, the louver body 2 can be precisely and tightly fitted into the inclined groove 5. Glue is applied inside the inclined groove 5 to further enhance the stability of the initial connection. Then, the screw 8 is inserted into the countersunk hole 6 above the inclined groove 5 on the top surface of the fixing base 4. Since the surface of the louver body 2 has a through hole, and the inner diameter of the through hole is equal to the outer diameter of the screw 8, the screw 8 can pass smoothly through the through hole of the louver body 2. After the bottom end of the screw 8 extends through the bottom surface of the fixing base 4 to the outside of the fixing base 4, the nut 9 is screwed onto the outer surface of the screw 8. By tightening the nut 9, the screw 8 generates a downward pulling force, which drives the limiting plate 7 (the outer diameter of the limiting plate 7 is equal to the inner diameter of the countersunk hole 6) to press tightly against the surface of the fixing base 4, thereby firmly fixing the louver body 2 to the fixing base 4. When the composite diamond louver is installed and begins operation, the grinding equipment drives the connecting seat 1 to rotate. The connecting seat 1 transmits the rotational power to the louver body 2 through the fixed seat 4. During high-speed rotation, the louver body 2 grinds the workpiece. The heat generated is dissipated through the heat dissipation holes 3 on the surface of the connecting seat 1. At the same time, the double fixing structure of the inclined groove 5 and the screw 8-nut 9-limiting plate 7 ensures that the louver body 2 maintains a stable connection under high temperature and high-speed rotation conditions, and will not fall off due to factors such as deterioration of adhesive performance or centrifugal force, thus achieving efficient and safe grinding work.
