Description

A marine-grade reinforced grinding wheel with built-in explosion-proof fiber mesh Technical Field

[0001] This utility model relates to the field of grinding wheel devices, and in particular to a marine reinforced grinding wheel with built-in explosion-proof fiber mesh. Background Technology

[0002] Grinding wheels, also known as bonded abrasives, are abrasives made by bonding ordinary abrasive grains together with a binder to form a specific shape and strength. They are generally composed of abrasive grains, binder, and pores, which are often referred to as the three essential elements of bonded abrasives. Grinding wheels are the most widely used and extensive type of abrasive. They rotate at high speeds during use and can be used for rough grinding, semi-finishing, and finishing of the outer and inner diameters, planes, and various profiles of metal or non-metal workpieces.

[0003] Currently, ordinary marine grinding wheels have a relatively simple structure. When faced with the high-intensity and high-load grinding requirements in shipbuilding, they are prone to breakage due to excessive pressure and torque. This not only endangers the safety of operators but may also damage the ship parts being processed, causing economic losses. In addition, conventional grinding wheels lack explosion-proof measures. Once they break, fragments will fly everywhere, posing a great threat to the personal safety of operators. In the relatively enclosed and equipment-dense working environment of a ship, the danger is even more serious.

[0004] Therefore, it is necessary to propose a marine reinforced grinding wheel with built-in explosion-proof fiber mesh to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a marine reinforced grinding wheel with a built-in explosion-proof fiber mesh, in order to solve the problem mentioned in the background art that ordinary marine grinding wheels are prone to breakage due to excessive pressure and torque when facing the high-intensity and high-load grinding requirements in shipbuilding, thereby endangering the safety of operators.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a marine reinforced grinding wheel with built-in explosion-proof fiber mesh, comprising a grinding wheel body, wherein a grinding surface is provided on the outer surface of the grinding wheel body;

[0007] Mounting blocks are installed at the center of both the front and rear surfaces of the grinding wheel body. Mounting blocks have mounting holes at their centers and repair fluid tanks inside. The repair fluid tanks are annular in design. A second wedge block is installed on one side of the repair fluid tank, and a first wedge block is installed on the other side. Both the first and second wedge blocks have holes.

[0008] Preferably, the first wedge block is arranged with its flat surface facing upwards, and the second wedge block is arranged with its inclined surface facing upwards.

[0009] Preferably, multiple holes are provided, which are evenly distributed at equal intervals on the first wedge block and the second wedge block, and the holes penetrate through the first wedge block and the second wedge block.

[0010] Preferably, an injection port is provided above the mounting hole and located on the front surface of the mounting block, and an extraction port is provided below the mounting hole and located on the front surface of the mounting block. Both the injection port and the extraction port are connected to the repair fluid tank.

[0011] Preferably, a sealing ring is provided inside the mounting block near the rear position, and two sealing rings are provided.

[0012] Preferably, the front surface of the mounting block is spirally fitted with four fastening bolts, which are symmetrically distributed on the mounting block in a circle. The grinding wheel body is detachably connected to the mounting block via the fastening bolts.

[0013] Preferably, heat dissipation grooves are provided on both the front and rear surfaces of the grinding wheel body.

[0014] Preferably, the grinding wheel body is equipped with an explosion-proof fiber mesh inside.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. In this utility model, the repair fluid tank set inside the mounting block and the injection hole connected thereto facilitate the storage and replenishment of repair fluid, ensuring that the repair fluid can be supplied in time when the grinding wheel cracks, maintaining the stable grinding performance of the grinding wheel. At the same time, the repair fluid can be recycled after use, saving usage costs. This solves the problem that ordinary marine grinding wheels are prone to breakage due to excessive pressure and torque when subjected to high-intensity and high-load grinding requirements.

[0017] 2. In this utility model, the heat dissipation groove and explosion-proof fiber mesh can effectively ensure production safety. The heat dissipation groove can dissipate the heat generated by grinding in time, preventing the grinding wheel from deteriorating due to overheating. At the same time, the built-in explosion-proof fiber mesh can effectively block the flying of fragments when the grinding wheel breaks, reducing the risk of injury to operators and surrounding equipment. It is especially suitable for marine applications and other scenarios with strict safety requirements, ensuring safe operation. Attached Figure Description

[0023] This utility model provides a marine reinforced grinding wheel with built-in explosion-proof fiber mesh, as shown in Figures 1 and 2. It includes a grinding wheel body 1, and a grinding surface 2 is provided on the outer surface of the grinding wheel body 1. The grinding wheel body 1 is a ceramic diamond grinding wheel. Ceramic diamond grinding wheels have the advantages of high strength, good heat resistance, sharp cutting edge, high grinding efficiency, and are not prone to heat generation and clogging during grinding. They also have small thermal expansion, which helps to control the machining accuracy.

[0024] Furthermore, mounting blocks 4 are installed at the center of both the front and rear surfaces of the grinding wheel body 1. Mounting holes 6 are opened at the center of the mounting blocks 4. The mounting holes 6 can be precisely aligned with the spindle of the grinding equipment. The mounting blocks 4 play a transition and stable support role. The grinding wheel body 1 is installed onto the spindle through the mounting holes 6. At the same time, the mounting blocks 4 ensure that the grinding wheel can be stably fixed on the equipment when rotating at high speed, avoiding problems such as shaking and displacement during the grinding process due to unstable installation, and ensuring the accuracy and stability of the grinding work.

[0025] Specifically, four fastening bolts 5 are spirally installed on the front surface of the mounting block 4. The grinding wheel body 1 is detachably connected to the mounting block 4 via the fastening bolts 5. The fastening bolts 5 are anti-loosening nuts with nylon rings. After the nut is tightened, the nylon ring fits tightly with the bolt thread, generating additional friction. As the equipment vibrates continuously, the anti-loosening nut can effectively resist the vibration and prevent the nut from loosening.

[0026] Furthermore, heat dissipation grooves 3 are provided on both the front and rear surfaces of the grinding wheel body 1. Based on the principles of heat conduction and convection, the contact area between the grinding wheel and the air is increased. When the grinding wheel rotates at high speed, the friction between the abrasive grains and the workpiece generates a large amount of heat. The heat is conducted through the grinding wheel body 1 to the surface of the heat dissipation grooves 3, and then dissipated through air convection, thus extending the service life of the grinding wheel.

[0027] Please refer to Figure 3. The mounting block 4 has a repair fluid tank 9 inside. The repair fluid tank 9 has a ring-shaped design and stores repair fluid, which is epoxy resin adhesive. During the use of grinding wheels, cracks often appear in the middle of the grinding wheel. This is due to improper use of the grinding wheel, leading to overload operation, and the lack of regular maintenance and inspection. When minute cracks appear, they are not addressed promptly. The epoxy resin adhesive in the repair fluid tank 9 moves within the tank during use due to the centrifugal force generated by the rotation of the grinding wheel, maintaining its fluidity. During grinding, when a crack appears in the middle of the grinding wheel, the epoxy resin adhesive quickly enters the crack and repairs it. The high temperature generated inside the grinding wheel during grinding accelerates the curing of the epoxy resin adhesive, thus achieving a self-healing function and ensuring that the grinding wheel will not suddenly burst during grinding.

[0028] Specifically, a second wedge block 11 is installed on one side of the inside of the repair liquid tank 9, and a first wedge block 10 is installed on the other side of the inside of the repair liquid tank 9. Holes 12 are opened on both the first wedge block 10 and the second wedge block 11. During the rotation of the grinding wheel, the epoxy resin will be continuously broken up and repolymerized through the holes 12, thereby ensuring that the epoxy resin will not harden in the repair liquid tank 9.

[0029] Specifically, the first wedge 10 is set with its flat surface facing upwards, and the second wedge 11 is set with its inclined surface facing upwards. This design allows the epoxy resin adhesive to always move towards the surface of the grinding wheel body 1 along the path formed by the inclined direction of the first wedge 10 and the second wedge 11. In this way, when cracks appear in the grinding wheel body 1, the epoxy resin adhesive can penetrate and repair them immediately.

[0030] Specifically, multiple holes 12 are provided and are evenly distributed on the first wedge block 10 and the second wedge block 11 at equal intervals. The holes 12 penetrate the first wedge block 10 and the second wedge block 11.

[0031] Furthermore, an injection port 7 is provided above the mounting hole 6 and on the front surface of the mounting block 4, and an extraction port 8 is provided below the mounting hole 6 and on the front surface of the mounting block 4. Both the injection port 7 and the extraction port 8 are connected to the repair fluid tank 9. Before using the grinding wheel, epoxy resin is injected into the injection port 7. After the grinding wheel is used up, the unused epoxy resin is extracted from the extraction port 8 for reuse, thus saving production costs.

[0032] Furthermore, a sealing ring 14 is provided inside the mounting block 4 near the rear. There are two sealing rings 14. The sealing rings 14 are used to fill the tiny gap between the mounting block 4 and the grinding wheel body 1 to form a sealing barrier. This can effectively prevent epoxy resin from leaking from the connection between the mounting block 4 and the grinding wheel body 1, ensuring that the epoxy resin is stored normally in the repair liquid tank 9 and maintaining the stable operation of the repair function.

[0033] Please refer to Figure 4. An explosion-proof fiber mesh 13 is installed inside the grinding wheel body 1. When the grinding wheel breaks due to various reasons (such as overload, material defects, etc.) during high-speed rotation, the explosion-proof fiber mesh 13 can effectively block the flying fragments and avoid injury to the operator and surrounding equipment, further improving the safety during use and meeting the needs of work scenarios with extremely high safety requirements, such as marine applications.

[0034] During use, the grinding wheel is installed on the grinding equipment through the mounting hole 6 in the center of the mounting block 4. When the equipment is started, the grinding wheel rotates at high speed, and the outer surface grinding surface 2 contacts the marine component for grinding. The heat generated during grinding is dissipated through the heat dissipation grooves 3 on the front and rear surfaces. At the same time, the epoxy resin in the repair liquid tank 9 is replenished through the injection port 7. When the grinding wheel develops cracks, the epoxy resin can be repaired in time to prevent the cracks from expanding further and causing a burst. After the grinding wheel is used up, the unused epoxy resin can be collected through the extraction port 8 for reuse, saving production costs. Throughout the entire working process, the built-in explosion-proof fiber mesh 13 ensures safety and prevents fragments from flying when the grinding wheel breaks until the grinding work is completed. The double explosion-proof design increases the safety of the grinding wheel during use.
