Description
Technical Field
[0001] This utility model relates to the field of grinding equipment technology, and in particular to a diamond flocked grinding disc. Background Technology
[0002] Diamond grinding wheels are a type of diamond tool, primarily used for surface grinding of various refractory materials. Currently, commercially available diamond grinding wheels consist of a grinding wheel base and multiple diamond cutting heads fixed to the base. These cutting heads are arranged in a ring, perpendicular to the radial direction of the grinding wheel base. A mounting hole is located at the center of the grinding wheel base, surrounded by positioning holes. In use, the cutting heads are mounted outwards at the output end of a drive unit. When the drive unit rotates, it drives the diamond grinding wheel to rotate, thus completing the polishing process on the workpiece.
[0003] The existing Chinese patent with publication number CN216657632U discloses diamond grinding discs. The existing technical solution described above has the following defects: Although the above technical solution achieves the effect of sharpening by setting a protruding structure on the upper end face of the grinding disc tip to complete the wear of the initial wear surface and the basic wear surface and expose the diamond in sequence, thus saving the process of sharpening with a separate grinding wheel, avoiding material waste, improving the service life of the grinding disc tip, and improving work efficiency, and also avoiding a large amount of dust pollution generated during the sharpening process, the grinding disc tip and the grinding disc base are fixedly connected in the above technical solution. This means that when a single tip is damaged, it cannot be replaced independently. The entire diamond grinding disc must be replaced, which not only increases the cost of use, but also reduces the practicality and economy of the product. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a diamond flocked grinding disc that allows for the individual disassembly and replacement of damaged grinding disc tips, reducing usage costs and improving the practicality and economy of the product, thereby solving the problems mentioned in the background technology.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a diamond flocked grinding disc, comprising a grinding disc body, a positioning hole being formed around the top surface of the grinding disc body, a grinding disc cutter being provided above the grinding disc body, and a positioning block being fixedly connected at the middle position of the bottom surface of the grinding disc cutter, one end of the positioning block extending into the interior of the positioning hole, a through hole being formed around the outer surface of the grinding disc body, and an insert rod passing through the through hole, one end of the insert rod passing through the positioning block and extending into the interior of an insertion hole formed on one side of the inner wall of the positioning hole, a limiting block being fixedly connected to the top and bottom surfaces of the insert rod, and one end of the limiting block extending into the interior of limiting grooves formed on both sides of the inner wall of the through hole, a spring being sleeved on the outer surface of the insert rod on one side of the limiting block, and a fixing ring being fixedly installed on the bottom surface of the grinding disc body.
[0006] Preferably, one end of the insert rod is provided with a pull ring on the outside of the grinding disc body, and the pull ring is fixedly welded to the insert rod.
[0007] Preferably, a heat dissipation hole is provided through the top surface of the grinding disc body on the side away from the positioning hole. A total of multiple heat dissipation holes are provided, and the multiple heat dissipation holes are evenly distributed around the top surface of the grinding disc body.
[0008] Preferably, a flocked layer is fixedly connected to the top surface of the grinding disc.
[0009] Preferably, the limiting block and the limiting groove are rectangular structures, the width of the limiting block is smaller than the width of the limiting groove, and one end of the limiting block extends into the interior of the limiting groove and is slidably connected to the limiting groove.
[0010] Preferably, the diameter of the insertion rod is smaller than the diameter of the insertion hole, and one end of the insertion rod is inserted into the insertion hole.
[0011] Preferably, the diameter of the positioning block is smaller than the diameter of the positioning hole, and the positioning block is inserted into the positioning hole.
[0012] Compared with the prior art, this utility model provides a diamond flocked grinding disc, which has the following beneficial effects:
[0013] (1) In this utility model, pulling the pull ring on one side of the grinding disc body will move the connecting rod to the through hole position. At this time, the positioning block at the bottom of the grinding disc head will be inserted into the positioning hole of the grinding disc body. After releasing the pull ring, the spring on the outside of the connecting rod will automatically pass through the positioning block and enter the insertion hole, realizing the quick fixed installation of the grinding disc head. When it is necessary to replace the damaged grinding disc head, pull the pull ring again to make the connecting rod completely exit the insertion hole and enter the through hole. Then the grinding disc head can be moved up to make the positioning block disengage from the positioning hole, thus completing the disassembly of a single grinding disc head. This enables the modular replacement of the grinding disc head, significantly reducing the cost of use, while improving the practicality and economy of the product, and effectively making up for the defects of the original fixed structure.
[0014] (2) In this utility model, the movement trajectory of the insertion rod is effectively constrained by the cooperation structure of the limiting block and the limiting groove, preventing it from tilting or shaking during movement, ensuring that the insertion rod can be accurately aligned and stably inserted into the insertion hole, thereby improving the reliability and convenience of the grinding disc head fixing operation; at the same time, the heat dissipation holes set on the grinding disc body can significantly improve the heat conduction efficiency, dissipate the heat generated by the grinding disc body during operation in a timely manner, maintain its normal operating temperature, and avoid affecting performance or life due to overheating, thereby enhancing the structural stability and continuous operation capability of the product.

[0024] Please see Figure 1-4A diamond flocked grinding disc includes a grinding disc body 1. A positioning hole 7 is formed around the top surface of the grinding disc body 1. A grinding disc head 2 is positioned above the grinding disc body 1, and a positioning block 8 is fixedly connected to the middle of the bottom surface of the grinding disc head 2. One end of the positioning block 8 extends into the interior of the positioning hole 7. The positioning hole 7 and the positioning block 8 are circular, with the diameter of the positioning block 8 smaller than the diameter of the positioning hole 7, facilitating the insertion of the positioning block 8 into the positioning hole 7. A through hole 12 is formed around the outer surface of the grinding disc body 1, and an insertion rod 6 passes through the through hole 12. One end of the insertion rod 6 passes through the positioning block 8 and extends into the interior of an insertion hole 5 formed on one side of the inner wall of the positioning hole 7, allowing the insertion rod 6 to move within the through hole 12, facilitating its insertion through the positioning block 8 and into the insertion hole 5, thereby facilitating the positioning of the grinding disc head 2. A limiting block 9 is fixedly connected to the top and bottom surfaces of the insertion rod 6, and one end of the limiting block 9 extends... Inside the limiting grooves 10 opened on both sides of the inner wall of the through hole 12, the limiting block 9 is slidably connected to the limiting groove 10 to facilitate the limiting of the insertion rod 6; a spring 11 is sleeved on the outer surface of the insertion rod 6 on one side of the limiting block 9. The use of the spring 11 facilitates the automatic reset of the insertion rod 6, thereby facilitating the insertion rod 6 to enter the insertion hole 5; a fixing ring 4 is fixedly installed on the bottom surface of the grinding disc body 1, which can fix the grinding disc body 1 on the drive device; when the grinding disc cutter head 2 is damaged, the pull ring 13 is pulled directly to move the insertion rod 6 at one end of the pull ring 13. When the insertion rod 6 moves away from the insertion hole 5 until one end of the insertion rod 6 enters the through hole 12, the grinding disc cutter head 2 is moved upward, so that the positioning block 8 moves away from the positioning hole 7, and the grinding disc cutter head 2 can be disassembled and replaced. Thus, the damaged grinding disc cutter head 2 can be disassembled and replaced separately, reducing its usage cost.
[0025] Please see Figure 1 and Figure 3 One end of the insertion rod 6 is provided with a pull ring 13 on the outside of the grinding disc body 1. The pull ring 13 is fixedly welded to the insertion rod 6. The use of the pull ring 13 makes it convenient to pull the insertion rod 6 for movement.
[0026] Please see Figure 1 and Figure 3 A heat dissipation hole 3 is provided through the top surface of the grinding disc body 1 on the side away from the positioning hole 7. Multiple heat dissipation holes 3 are provided and are evenly distributed around the top surface of the grinding disc body 1. The heat dissipation holes 3 are circular. Through the use of heat dissipation holes 3, the heat generated by the grinding disc body 1 during operation can be dissipated in time, maintaining its normal operating temperature and avoiding performance or lifespan affected by overheating, thereby enhancing the structural stability and continuous operation capability of the product.
[0027] Please see Figure 3The top surface of the grinding disc cutter head 2 is fixedly connected with a flocked layer, which can strengthen the grinding disc cutter head 2 and thus improve its strength.
[0028] Please see Figure 1 and Figure 2 The limiting block 9 and the limiting groove 10 are rectangular structures. The width of the limiting block 9 is smaller than the width of the limiting groove 10. One end of the limiting block 9 extends into the interior of the limiting groove 10 and slides in connection with the limiting groove 10. The cooperation structure between the limiting block 9 and the limiting groove 10 effectively constrains the movement trajectory of the insertion rod 6, preventing it from tilting or shaking during movement. This ensures that the insertion rod 6 can be accurately aligned and stably inserted into the insertion hole 5, thereby improving the reliability and convenience of the grinding head 2 fixing operation.
[0029] Please see Figure 1 and Figure 2 The diameter of the plug rod 6 is smaller than the diameter of the socket 5. One end of the plug rod 6 is inserted into the socket 5, which makes it easy to insert the plug rod 6 into the socket 5.
[0030] Please see Figure 1 , Figure 2 and Figure 4 The diameter of the positioning block 8 is smaller than the diameter of the positioning hole 7. The positioning block 8 is inserted into the positioning hole 7, which facilitates the insertion of the positioning block 8 into the positioning hole 7, thereby making it convenient to install and fix the grinding disc cutter head 2.
[0031] Working principle:
[0032] In use, pull the pull ring 13 on one side surface of the grinding disc body 1 to move the insertion rod 6 on one side surface of the pull ring 13. When one end of the insertion rod 6 enters the through hole 12, the positioning block 8 on the bottom surface of the grinding disc cutter head 2 is inserted into the positioning hole 7 on the grinding disc body 1. After insertion, release the pull ring 13. Through the action of the spring 11 on the outer surface of the insertion rod 6, one end of the insertion rod 6 will automatically pass through the positioning block 8 and enter the insertion hole 5, thereby fixing the grinding disc cutter head 2 on the grinding disc body 1. If the grinding disc cutter head 2 is damaged, pull the pull ring 13 directly to move the insertion rod 6 at one end of the pull ring 13. When the insertion rod 6 moves away from the insertion hole 5 until one end of the insertion rod 6 enters the through hole 12, move the grinding disc cutter head 2 upward. This allows the positioning block 8 to be moved away from the positioning hole 7, enabling the grinding disc head 2 to be disassembled and replaced. This allows for individual disassembly and replacement of damaged grinding disc heads 2, reducing usage costs. The cooperation structure between the limiting block 9 and the limiting groove 10 effectively constrains the movement trajectory of the insertion rod 6, preventing it from tilting or shaking during movement. This ensures that the insertion rod 6 can be accurately aligned and stably inserted into the insertion hole 5, thereby improving the reliability and convenience of fixing the grinding disc head 2. At the same time, the heat dissipation holes 3 provided on the grinding disc body 1 can significantly improve heat conduction efficiency, dissipating the heat generated by the grinding disc body 1 during operation and maintaining its normal operating temperature. This avoids performance or lifespan being affected by overheating, thereby enhancing the structural stability and continuous operation capability of the product.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
