Description

A core-reinforced ultrathin and ultra-tough grinding wheel Technical Field

[0001] This utility model relates to the field of grinding wheel technology, and in particular to a core-reinforced ultra-thin and ultra-tough grinding wheel. Background Technology

[0002] Grinding wheels are classified into diamond cutting wheels and fiber resin cutting wheels according to their materials. They are widely used in carbon steel, mold steel, bearing steel, light alloys, glass and ceramics and other fields. With the continuous improvement of manufacturing technology, there are higher requirements for the cutting accuracy, service life and bending and compressive strength of cutting wheels in the field of metal processing and cutting. As a result, fiber resin grinding wheels have emerged. These fiber resin grinding wheels not only have high rigidity, but also have good impact resistance and bending and compressive strength, and their service life has been greatly improved.

[0003] A search revealed that application number CN202420395341.2 describes a variable aperture flat resin grinding wheel. This grinding wheel not only has effective strength but can also be installed and fixed through a core hole. Furthermore, a replacement block can be pressed and separated through a groove to form another through hole, allowing for the installation of a different shaped structure through the groove. This effectively improves the ease of use and applicability of the grinding wheel, enhancing the user's experience.

[0004] The aforementioned utility model allows the entire grinding wheel to be installed on a mandrel of different specifications by replacing the replacement block. This requires the operator to prepare a replacement block suitable for the grinding wheel in advance when using the grinding wheel. Furthermore, when replacing the replacement block, it is necessary to use force to break the connecting plate to remove the replacement block, which makes the overall use of the grinding wheel quite cumbersome.

[0005] To address these shortcomings, we propose a core-reinforced ultra-thin and ultra-tough grinding wheel. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a core-reinforced ultra-thin and ultra-tough grinding wheel.

[0008] Preferably, the side surface of the grinding wheel is provided with heat dissipation holes, and there are multiple heat dissipation holes, which are distributed in a ring array on the side surface of the grinding wheel. The air inlet of the heat dissipation hole is larger than the air outlet of the heat dissipation hole.

[0009] Preferably, the surface of the positioning post is threaded, and a nut is threadedly connected to the thread.

[0010] Preferably, the inner side of the fixing ring is provided with a groove, and the inner side of the groove is provided with a guide groove. A guide bar is provided in the guide groove, and the guide bar is located on the side surface of the clamping plate.

[0011] Preferably, the side surface of the rotating ring is provided with anti-slip texture.

[0012] Preferably, the grinding wheel is composed of abrasive, fiberglass mesh, binder and metal mesh, with fiberglass mesh on the outer side of the metal mesh, and abrasive bonded to the outer side of the fiberglass mesh by a binder.

[0013] This utility model has the following advantages:

[0014] (1) When using this utility model, the grinding wheel is placed directly on the mandrel, and then the rotating ring is rotated to drive the positioning hole, causing the positioning pin to move, thereby driving the clamping plate so that the clamping plate fits with the mandrel. Then, multiple partitions are respectively put on the fixing pin and the mandrel, and the threaded nuts are connected to complete the installation of the grinding wheel. This utility model has a simple structure and is easy to operate. By adjusting the spacing between the clamping plates, it can adapt to mandrels of different specifications, which greatly improves the practicality of the grinding wheel.

[0015] (2) In this utility model, by setting heat dissipation holes, when the grinding wheel is rotating at high speed, some of the air on the side of the grinding wheel is guided to the grinding surface of the grinding wheel through the air inlet of the heat dissipation hole and the air outlet, thereby accelerating the heat dissipation of the grinding wheel and reducing the damage to the grinding wheel during use.

[0028] As shown in Figures 1-5, a core-reinforced ultra-thin and ultra-tough grinding wheel includes a mandrel 1. A clamping plate 8 is provided on the outer side of the mandrel 1. The clamping plate 8 is slidably connected to a fixing ring 2. A grinding wheel 3 is provided on the outer side of the fixing ring 2. A rotating ring 4 is rotatably provided on the surface of the fixing ring 2.

Multiple nuts are threadedly connected to the mandrel 1 and the fixing pin 11 respectively.

[0029] In one embodiment, during use, the grinding wheel is placed directly on the mandrel 1, and then the rotating ring 4 is rotated to drive the positioning hole 6, causing the positioning pin 7 to move, thereby driving the clamping plate 8 so that the clamping plate 8 fits against the mandrel 1. Then, multiple partitions are respectively fitted onto the fixing pin 11 and the mandrel 1, and threaded nuts are connected to complete the installation of the grinding wheel 3. This utility model has a simple structure and is easy to operate. By adjusting the spacing between the clamping plates 8, it can adapt to mandrels 1 of different specifications, which greatly improves the practicality of the grinding wheel.

[0030] Specifically, the side surface of the grinding wheel 3 is provided with heat dissipation holes 12, and there are multiple heat dissipation holes 12. The multiple heat dissipation holes 12 are distributed in a ring array on the side surface of the grinding wheel 3, and the air inlet of the heat dissipation hole 12 is larger than the air outlet of the heat dissipation hole 12.

[0031] In one embodiment, by providing heat dissipation holes 12, when the grinding wheel is rotating at high speed, some of the air on the side of the grinding wheel is guided to the grinding surface of the grinding wheel 3 through the air inlet of the heat dissipation holes 12 and the air outlet, thereby accelerating the heat dissipation of the grinding wheel 3 and reducing the wear and tear on the grinding wheel.

[0032] Specifically, the surface of the positioning post 7 is threaded, and a nut is threadedly connected to the thread.

[0033] In one embodiment, a nut is used to fix the rotating ring 4 to prevent it from shaking when the grinding wheel 3 rotates, thus affecting the overall stability of the grinding wheel.

[0034] Specifically, the inner side of the fixing ring 2 is provided with a groove, and the inner side of the groove is provided with a guide groove. A guide bar is provided in the guide groove, and the guide bar is located on the side surface of the clamping plate 8.

[0036] Specifically, the side surface of the rotating ring 4 is provided with anti-slip texture 5.

[0037] In one embodiment, by setting anti-slip texture 5, the friction between the finger and the rotating ring 4 is increased, thereby achieving an anti-slip effect.

[0038] Specifically, the grinding wheel 3 is composed of abrasive 13, fiberglass mesh 14, binder and metal mesh 15. Fiberglass mesh 14 is provided on the outer side of the metal mesh 15, and abrasive 13 is bonded to the outer side of the fiberglass mesh 14 by the binder.

[0040] The working process of this utility model is as follows: In use, the grinding wheel is placed directly on the mandrel 1, and then the rotating ring 4 is rotated to drive the positioning hole 6, causing the positioning pin 7 to move, thereby driving the clamping plate 8, so that the clamping plate 8 fits against the mandrel 1. Then, multiple partitions are respectively fitted onto the fixing pin 11 and the mandrel 1, and the threaded nuts are connected to complete the installation of the grinding wheel 3. This utility model has a simple structure and is easy to operate. By adjusting the spacing between the clamping plates 8, it can adapt to different specifications of mandrel 1, which greatly improves the practicality of the grinding wheel. By setting the heat dissipation hole 12, when the grinding wheel is rotating at high speed, some of the air on the side of the grinding wheel is guided to the grinding surface of the grinding wheel 3 through the air inlet of the heat dissipation hole 12 and the air outlet, which accelerates the heat dissipation of the grinding wheel 3 and reduces the damage to the grinding wheel during use.
