Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, specifically a composite grinding wheel. Background Technology

[0002] A grinding wheel is a tool used for grinding, polishing, and polishing various materials. Driven by a motor, it rotates at high speed. The workpiece to be ground is brought close to the grinding wheel, and the grinding wheel grinds the workpiece.

[0003] Chinese Patent No. 201710728445.5 discloses a rail grinding wheel and its preparation method, belonging to the field of grinding wheel technology. The rail grinding wheel includes a base and a grinding body. A through hole is formed in the middle of the base, and several mounting posts are evenly arranged around the through hole on one end face of the base. Several connecting posts are evenly arranged around the through hole on the other end of the base. The base is fixedly connected to the grinding body through the connecting posts. Glass fiber filaments are wound around the outer wall of the grinding body.

[0004] When using this utility model, the grinding coefficient is relatively simple, and it is necessary to change the grinding wheel or grinding equipment when performing different stages of grinding, which is very inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a composite grinding wheel to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a composite grinding wheel, comprising a grinding wheel body; the grinding wheel body is composed of a PVC rotating wheel, a first-order grinding wheel, a second-order grinding wheel, and a third-order grinding wheel; the PVC rotating wheel is configured in a tower shape, and a mounting hole is provided inside the PVC rotating wheel; the first-order grinding wheel, the second-order grinding wheel, and the third-order grinding wheel are sequentially fitted onto the outside of the PVC rotating wheel; the first-order grinding wheel, the second-order grinding wheel, and the third-order grinding wheel are composed of a grinding layer and a metal substrate; the grinding wheel friction coefficients on the upper sides of the first-order grinding wheel, the second-order grinding wheel, and the third-order grinding wheel decrease sequentially; the grinding layer is bonded to the outside of the metal substrate by an adhesive; mounting plates are installed around the inner perimeter of the metal substrate; mounting holes are provided on the upper side of the PVC rotating wheel corresponding to the positions of the mounting plates; the mounting plates are embedded inside the mounting holes; and the mounting plates and the mounting holes are fixed together by bolts.

[0007] Preferably, the outer side of the metal substrate is provided with a groove, and the polishing layer is embedded inside the groove.

[0008] Preferably, the inner side of the metal substrate is provided with a protrusion, which is embedded inside the PVC wheel.

[0009] Preferably, a steel sleeve is provided inside the mounting hole, and the steel sleeve is embedded inside the mounting hole.

[0010] Preferably, a heat-conducting plate is provided inside the PVC wheel, the heat-conducting plate is embedded inside the PVC wheel, and the outer side of the heat-conducting plate is in contact with the metal substrate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Since the friction coefficients of the first-order, second-order, and third-order grinding wheels decrease sequentially, during grinding, depending on different grinding needs and stages, one can start with the first-order grinding wheel with a higher friction coefficient to provide greater friction for initial grinding. As grinding progresses, one can gradually transition to the second-order and third-order grinding wheels with lower friction coefficients to achieve a finer grinding effect without the need for frequent replacement of the grinding wheel body, thus extending the service life of the grinding wheel body.

[0013] 2. The protrusions on the inner side of the metal substrate are embedded inside the PVC wheel. This structure increases the connection strength and positioning accuracy between the metal substrate and the PVC wheel. When the grinding wheel rotates for grinding, the metal substrate and the PVC wheel need to remain relatively fixed to ensure the accuracy and stability of the grinding. The embedded cooperation between the protrusions and the PVC wheel can better transmit torque and prevent the metal substrate from rotating relative to the PVC wheel, thus making the entire grinding wheel more stable and reliable during operation.

[0014] 3. The steel sleeve is likely designed to enhance the strength and wear resistance of the mounting hole. During the installation and operation of the grinding wheel, the mounting hole will be subjected to certain pressure and friction. The steel sleeve has high strength and hardness, which can effectively resist the action of these external forces, protect the mounting hole from damage, extend the service life of the mounting hole, and also ensure the stability of the grinding wheel installation, ensuring that the grinding wheel will not loosen or have other problems when it rotates at high speed for grinding.

[0015] 4. During the polishing process, friction generates a large amount of heat. If this heat cannot be dissipated in time, it will cause the temperature of the polishing layer to rise, affecting the performance and service life of the polishing layer, and may even affect the polishing effect. The function of the heat-conducting plate is to quickly conduct the heat generated by the metal substrate during polishing and dissipate it to the surrounding environment through the PVC roller, thereby reducing the temperature of the polishing layer, keeping the polishing layer working within a suitable temperature range, improving the stability and reliability of the polishing layer, and ensuring the smooth progress of the polishing work.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 In this embodiment of the present invention, a composite grinding wheel includes a grinding wheel body 1. The grinding wheel body 1 is composed of a PVC rotating wheel 9, a first-order grinding wheel 2, a second-order grinding wheel 3, and a third-order grinding wheel 4. The PVC rotating wheel 9 is configured in a tower shape, and a mounting hole 10 is provided inside the PVC rotating wheel 9. The first-order grinding wheel 2, the second-order grinding wheel 3, and the third-order grinding wheel 4 are sequentially fitted on the outside of the PVC rotating wheel 9. The first-order grinding wheel 2, the second-order grinding wheel 3, and the third-order grinding wheel 4 are composed of a grinding layer 5 and a metal substrate 7. The grinding wheel friction coefficients on the upper side of the first-order grinding wheel 2, the second-order grinding wheel 3, and the third-order grinding wheel 4 decrease sequentially. The grinding layer 5 is bonded to the outside of the metal substrate 7 by an adhesive. Mounting pieces 11 are installed around the inner perimeter of the metal substrate 7. Mounting holes 10 are provided on the upper side of the PVC rotating wheel 9 corresponding to the positions of the mounting pieces 11. The mounting pieces 11 are embedded inside the mounting holes 10, and the mounting pieces 11 and the mounting holes 10 are fixed together by bolts.

[0025] A groove 6 is provided on the outer side of the metal substrate 7, and the polishing layer 5 is embedded in the groove 6. The design of the groove 6 further enhances the connection stability between the polishing layer 5 and the metal substrate 7. During the polishing process, the polishing layer 5 will be subjected to various forces, such as friction and impact. The presence of the groove 6 can effectively prevent the polishing layer 5 from shifting or falling off under the action of these forces, thereby ensuring the continuous and effective polishing work, extending the service life of the polishing layer 5, and also ensuring the consistency of the polishing effect.

[0026] The metal substrate 7 has a protrusion 8 on its inner side, which is embedded inside the PVC wheel 9. This structure increases the connection strength and positioning accuracy between the metal substrate 7 and the PVC wheel 9. When the grinding wheel rotates for grinding, the metal substrate 7 and the PVC wheel 9 need to remain relatively fixed to ensure the accuracy and stability of the grinding. The embedded cooperation between the protrusion 8 and the PVC wheel 9 can better transmit torque and prevent the metal substrate 7 from rotating relative to the PVC wheel 9, thereby making the entire grinding wheel more stable and reliable during operation.

[0027] A steel sleeve 14 is provided inside the mounting hole 10. The steel sleeve 14 is embedded inside the mounting hole 10. The steel sleeve 14 is probably set to enhance the strength and wear resistance of the mounting hole 10. During the installation and operation of the grinding wheel, the mounting hole 10 will be subjected to certain pressure and friction. The steel sleeve 14 has high strength and hardness, which can effectively resist the action of these external forces, protect the mounting hole 10 from damage, extend the service life of the mounting hole 10, and also ensure the stability of the grinding wheel installation, ensuring that the grinding wheel will not loosen or have other problems when it rotates at high speed for grinding.

[0028] A heat-conducting plate 13 is installed inside the PVC roller 9. The heat-conducting plate 13 is embedded inside the PVC roller 9, and its outer side is in contact with the metal substrate 7. During the polishing process, a large amount of heat is generated due to friction. If this heat cannot be dissipated in time, it will cause the temperature of the polishing layer 5 to rise, affecting the performance and service life of the polishing layer 5, and may even affect the polishing effect. The function of the heat-conducting plate 13 is to quickly conduct the heat generated by the metal substrate 7 during polishing and dissipate it to the surrounding environment through the PVC roller 9, thereby reducing the temperature of the polishing layer 5, keeping the polishing layer 5 working within a suitable temperature range, improving the stability and reliability of the polishing layer 5, and ensuring the smooth progress of the polishing work.

[0029] The working principle and usage process of this utility model are as follows: In use, the first-order grinding wheel 2, the second-order grinding wheel 3, and the third-order grinding wheel 4 are fixedly installed on the upper side of the PVC grinding wheel 9 with bolts, which facilitates the individual replacement of the first-order grinding wheel 2, the second-order grinding wheel 3, and the third-order grinding wheel 4, without the need for individual replacement. Since the friction coefficients of the grinding wheels on the upper side of the first-order grinding wheel 2, the second-order grinding wheel 3, and the third-order grinding wheel 4 decrease sequentially, during grinding, according to different grinding needs and stages, we can start with the first-order grinding wheel 2 with a higher friction coefficient to provide greater friction for initial grinding. As grinding progresses, we gradually transition to the second-order grinding wheel 3 and the third-order grinding wheel 4 with lower friction coefficients to achieve a finer grinding effect without the need for frequent replacement of the grinding wheel body 1, thus extending the service life of the grinding wheel body 1.
