[0024] This utility model provides a modular quick-release mounting device for marine grinding wheels. Please refer to the appendix. Figure 1 -Appendix Figure 2 As shown, it includes a fixed shaft 5, a mounting plate 4 is fixedly installed on the lower surface of the fixed shaft 5, a split chuck 1 is installed below the mounting plate 4, and a grinding wheel body 2 is clamped on the lower surface of the split chuck 1.

[0025] Specifically, there are two split chucks 1. Each split chuck 1 is semi-circular, and a locking block 9 is fixedly installed on the upper surface of the split chuck 1. The locking block 9 has a hole 10. A high-pressure spring 13 is installed between the two split chucks 1. There are two high-pressure springs 13, which are symmetrically distributed along the axis. The semi-circular split chucks 1 are connected by the high-pressure springs 13 in the middle. When the marine grinding wheel rotates at high speed to grind the surface of the ship, it will encounter unevenness or other resistance on the surface of the ship and generate vibration. The high-pressure spring 13 can play a buffering role, absorb some of the vibration energy, and reduce the impact of vibration on the grinding wheel and the entire installation device. For example, when grinding the rust-covered parts of the old ship hull, it can effectively prevent the grinding wheel from breaking due to vibration, extend the service life of the grinding wheel and equipment, and reduce replacement costs.

[0026] Specifically, the outer surface of the split chuck 1 has a hole 10 that penetrates the split chuck 1. A first fastening bolt 6 is screwed into the hole 10. The first fastening bolt 6 penetrates the hole 10 on the split chuck 1. By tightening or loosening the bolt, the distance and tightness between the two split chucks 1 can be flexibly adjusted. When facing grinding wheel bodies 2 of different specifications and sizes, the opening and closing degree of the split chuck 1 can be easily adjusted to ensure stable clamping of the grinding wheel body 2, increase the versatility of the device, and reduce the need to replace the installation device due to different grinding wheel specifications.

[0027] The two separate chucks 1 form an upward slit 3, which provides a specific channel for dust. The fan blade 15 rotates to generate airflow, which forms a certain direction and suction force. Dust can move upward along the upward slit 3 and then be guided by the airflow driven by the fan blade 15 to the dust collection chamber 11 on the lower surface of the mounting plate 4. This can collect dust in a targeted manner, preventing dust from flying around in the working environment. This not only improves the working environment and reduces the harm to the health of operators, but also facilitates the centralized cleaning of dust in the later stage, thus improving the environmental protection and convenience of the entire grinding work.

[0028] Specifically, the holes 10 on the mounting plate 4 correspond to the holes 10 on the clamping block 9. The second fastening bolt 7 is spirally installed in the holes 10 on the mounting plate 4. This design ensures the reliability and accuracy of the connection between the mounting plate 4 and the split chuck 1. During installation, the holes 10 can be quickly aligned for installation, avoiding misalignment and ensuring the coaxiality of the entire mounting device. This makes the grinding wheel rotate more smoothly and reduces vibration and wear caused by installation errors.

[0029] Please see the appendix Figure 3 As shown, the split chuck 1 has a clamping cavity 12 on its lower surface. The grinding wheel body 2 is clamped in the clamping cavity 12. The clamping cavity 12 on the lower surface of the split chuck 1 can accurately clamp the grinding wheel body 2. Its shape and size are adapted to the grinding wheel body 2 to form a tight fit. When the grinding wheel rotates at high speed for grinding, it can effectively prevent the grinding wheel from shifting or shaking, ensuring the accuracy and safety of the grinding work. For example, when performing fine grinding work, it can ensure that the grinding wheel grinds according to the predetermined trajectory and force, thereby improving the grinding quality.

[0030] It should be noted that a silicone anti-slip layer is installed inside the clamping cavity 12. The silicone anti-slip layer has good elasticity and friction, which can not only enhance the fixing effect of the grinding wheel and prevent the grinding wheel from sliding in the cavity, but also avoid direct contact with metal materials to avoid damage to the coating or structure of the grinding wheel surface, thus extending the service life of the grinding wheel and improving the stability and reliability of the grinding work.

[0031] Please see the appendix Figure 4 -Appendix Figure 5As shown, a rim 8 is installed on the outer surface of the mounting plate 4 near the top. A fan blade 15 is installed on the lower surface of the rim 8. Multiple fan blades 15 are arranged symmetrically in a circle on the lower surface of the rim 8. The fan blades 15 rotate to generate airflow, which forms a certain suction force. Dust moves upward along the rising seam 3 and is then guided by the airflow driven by the fan blades 15 to the dust collection chamber 11 on the lower surface of the mounting plate 4.

[0032] Furthermore, holes 10 are provided on the upper surface of the mounting plate 4 near both sides, and the holes 10 penetrate the mounting plate 4. A slot 14 is provided on the lower surface of the mounting plate 4. When it is necessary to replace the grinding wheel body 2, only the first fastening bolt 6 needs to be loosened slightly. Under the action of the high-pressure spring 13, the two split chucks 1 will separate, and the grinding wheel body 2 can be quickly removed, achieving the purpose of quick disassembly. During installation, the grinding wheel body 2 is clamped in the clamping cavity 12, and then the first fastening bolt 6 is tightened to achieve quick installation.

[0033] Specifically, the slot 14 has a trapezoidal design that is wider at the top and narrower at the bottom. The locking block 9 corresponds to the slot 14 and slides within the slot 14. The trapezoidal design of the slot 14 works in conjunction with the locking block 9. When installing the split chuck 1, the locking block 9 can slide smoothly into the trapezoidal slot 14, which facilitates the installation operation. This design achieves modularity when changing grinding wheels of different specifications. By using split chucks 1 of different specifications, the installation of grinding wheels of different specifications can be achieved, thus improving the applicability of the device.

[0034] Specifically, the slot 14 divides the lower surface of the mounting plate 4 into two semicircles, and each semicircle has a dust collection chamber 11.

[0035] Specifically, the rim 8 is a circular design that is narrow at the top and wide at the bottom. When the fan blade 15 rotates to generate airflow, it helps to optimize the airflow direction, making the airflow more concentrated upward and guiding the dust.

[0036] When using the device, if the grinding wheel body 2 needs to be replaced, slightly loosen the first fastening bolt 6. Under the action of the high-pressure spring 13, the two split chucks 1 separate, and the old grinding wheel body 2 can be quickly removed. Then, follow the reverse installation steps to install the new grinding wheel body 2, achieving quick replacement. When a larger grinding wheel is needed, simply unscrew the second fastening bolt 7, replace with a larger split chuck 1, insert the chuck block 9 into the chuck slot 14, and use the second fastening bolt 7 to limit the split chuck 1. The modular design allows for the installation of grinding wheels of different specifications, improving the applicability of the device.
