Description

A marine grinding wheel with shock-absorbing and heat-dissipating grooves Technical Field

[0001] This utility model relates to a marine grinding wheel with shock-absorbing and heat-dissipating grooves. Background Technology

[0002] Marine grinding wheels are widely used in shipbuilding and repair for grinding and polishing metal materials on the hull. However, during prolonged use, grinding wheels generate a significant amount of heat due to friction, accompanied by a certain degree of vibration. Excessive temperature not only affects the service life of the grinding wheel but may also impact grinding quality. Furthermore, high temperature and vibration can accelerate equipment wear.

[0003] In traditional marine grinding wheels, due to their simple structure, heat dissipation mainly relies on the horizontal spraying of cooling medium. Although the horizontally sprayed cooling medium can cool the side surface of the grinding wheel, it cannot effectively reach the grinding surface in the direction of the grinding wheel's movement, thus reducing the cooling effect.

[0004] Therefore, how to cool the advancing face of the grinding wheel is a technical problem that needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a marine grinding wheel with shock-absorbing and heat-dissipating grooves. By additionally customizing two constraint discs on both sides of the grinding wheel disc to guide the direction of the cooling medium injection, the advancing surface of the grinding wheel is cooled. This invention achieves its purpose as follows:

[0006] This utility model relates to a marine grinding wheel with shock-absorbing and heat-dissipating grooves, comprising a main shaft, a fixing part rotatably mounted on the main shaft, a grinding wheel mounted on the fixing part, a first constraint plate mounted on the left end of the grinding wheel, and a second constraint plate mounted on the right end of the grinding wheel. The diameters of the first and second constraint plates are both smaller than the diameter of the grinding wheel. The distance between the first constraint plate and the grinding wheel is 2 mm, and the distance between the second constraint plate and the grinding wheel is 2 mm. Several guide blocks are circumferentially arranged on the side of the first and second constraint plates facing the grinding wheel. The guide blocks are bent in the direction of rotation of the grinding wheel, and the height of the guide blocks decreases towards the outer diameter of the first and second constraint plates. Protrusions are provided on the side of the first and second constraint plates facing the grinding wheel, and the protrusions are located between adjacent guide blocks. Heat dissipation grooves are provided on both sides of each protrusion, and the heat dissipation grooves penetrate the first and second constraint plates. The model also includes an oil nozzle, which is positioned facing the heat dissipation grooves and is fixed to a support frame.

[0007] Furthermore, to accommodate the wear of the grinding wheel, the diameter of the first constraint disc is 400mm, the diameter of the second constraint disc is 400mm, and the diameter of the grinding wheel is 390mm.

[0008] Furthermore, to enhance the cooling effect, two oil nozzles are provided, located on the outside of the first constraint plate and the outside of the second constraint plate, respectively.

[0009] Furthermore, in order to enhance the guiding effect of the cooling medium, the guide block is provided with 12 blocks.

[0010] Furthermore, in order to enhance the guiding effect of the cooling medium, the height of the guide block at the end furthest from the outer diameter of the first constraint disk is 1.9 mm, and the height of the guide block at the end closest to the outer diameter of the first constraint disk is 0.5 mm.

[0011] Furthermore, to enhance heat dissipation, the horizontal cross-sectional area of ​​each heat dissipation groove is larger than the horizontal cross-sectional area of ​​the protrusion.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the cooling medium is guided by the heat dissipation groove, the protrusion and the guide block to form an axial jet flow to cool the advancing surface of the grinding wheel, thereby improving the heat dissipation effect of the grinding wheel.

[0017] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0018] Please refer to Figures 1-3. An embodiment of this utility model relates to a marine grinding wheel 1 with shock-absorbing and heat-dissipating grooves 12. It includes a main shaft 3, a fixing part 2 rotatably mounted on the main shaft 3, and a grinding wheel 1 mounted on the fixing part 2. A first constraint disk 7 is mounted on the left end of the grinding wheel 1, and a second constraint disk 9 is mounted on the right end of the grinding wheel 1. The diameters of both the first constraint disk 7 and the second constraint disk 9 are smaller than the diameter of the grinding wheel 1. The distance between the first constraint disk 7 and the grinding wheel 1 is 2mm, and the distance between the second constraint disk 9 and the grinding wheel 1 is 2mm. The first constraint disk 7 and the second constraint disk 9 face the grinding wheel 1. Each side of the grinding wheel 1 is provided with several guide blocks 10 circumferentially. The guide blocks 10 are bent in the direction of rotation of the grinding wheel 1, and the height of the guide blocks 10 decreases towards the outer diameter of the first constraint disk 7 and the second constraint disk 9. The first constraint disk 7 and the second constraint disk 9 are each provided with a protrusion 11 on the side facing the grinding wheel 1. The protrusion 11 is located between adjacent guide blocks 10. Each protrusion 11 has a heat dissipation groove 12 on both sides, which penetrates the first constraint disk 7 and the second constraint disk 9. It also includes an oil nozzle 5, which is positioned facing the heat dissipation groove 12 and is fixed to the support frame 6. The grinding wheel 1 is cooled by additionally customizing two constraint disks on both sides of the grinding wheel 1 to guide the spray direction of the cooling medium. The grinding wheel 1 and the constraint disks are fixed by fixing pins 8.

[0019] In a specific application scenario, please refer to Figure 3. The grinding wheel 1 rotates clockwise, and S is the direction of the cooling medium. When using this device to grind the workpiece, the grinding wheel 1 rotates synchronously with the constraint disc. The oil supply and spray 5 provides the cooling medium through the oil supply pipe 4. When the oil supply nozzle 5 is opened, the cooling medium, which is oil or water, is sprayed out. During the cooling process, the cooling medium is sprayed from the left and right sides onto the grinding wheel 1. It first enters through the heat dissipation groove 12, then impacts the protrusion 11, and is split into two branches by the protrusion 11. The two branches are then guided by the guide block 10. Through the rotation of the grinding wheel 1, the horizontally sprayed cooling medium is transformed into an axial spray, and the cooling medium is better input to the front end of the grinding wheel 1 through the guide block 10.

[0020] In one specific embodiment, in order to accommodate the wear of the grinding wheel 1, the diameter of the first constraint disk 7 is 400mm, the diameter of the second constraint disk 9 is 400mm, and the diameter of the grinding wheel 1 is 390mm.

[0021] In one specific embodiment, in order to enhance the cooling effect, two oil nozzles 5 are provided, and are respectively located on the outside of the first constraint plate 7 and the outside of the second constraint plate 9.

[0022] In one specific embodiment, in order to enhance the guiding effect of the cooling medium, the guide block 10 is provided with 12 blocks.

[0023] In one specific embodiment, in order to enhance the guiding effect of the cooling medium, the height of the guide block 10 at the end away from the outer diameter of the first constraint disk 7 is 1.9 mm, and the height of the guide block 10 at the end close to the outer diameter of the first constraint disk 7 is 0.5 mm.

[0024] In one specific embodiment, in order to enhance the heat dissipation effect, the horizontal cross-sectional area of ​​each heat dissipation groove 12 is larger than the horizontal cross-sectional area of ​​the protrusion 11.

[0025] In another embodiment, the distance L between the first constraint disk 7 and the grinding wheel 1 is 2.5 mm, the diameter of the first constraint disk 7 is 395 mm, the diameter of the second constraint disk 9 is 395 mm, and the diameter of the grinding wheel 1 is 390 mm.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
