Description

Technical Field

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

[0002] Grinding equipment is a type of machinery used for grinding and polishing floor surfaces, walls, ceilings, cabinet panels, or similar objects. Its main working component is the grinding wheel, which rotates under the drive of a power mechanism to grind and polish floor surfaces, walls, cabinet surfaces, etc. It has a fast processing speed, high efficiency, and good quality. Diamond grinding wheels are a type of diamond tool.

[0003] The main problems with current diamond grinding wheels are as follows: (1) The same grinding wheel only has one grinding mode, such as only having coarse grinding or fine grinding functions. After coarse grinding is completed, the fine grinding wheel needs to be replaced. It is not possible to fine grind the object to be ground after coarse grinding, resulting in low grinding efficiency; (2) During grinding, the rotation of the grinding wheel generates centrifugal force, which stirs up the surrounding air and achieves heat dissipation. However, relying solely on the rotation of the grinding wheel itself, the wind force is small and the heat dissipation efficiency is poor. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a diamond grinding wheel that solves the problems mentioned in the background art, such as poor heat dissipation of existing grinding wheels and low grinding efficiency caused by the lack of integration of coarse and fine grinding.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A diamond grinding wheel includes a cylindrical base with two annular mounting grooves on its outer wall. A coarse grinding wheel is detachably connected to one mounting groove, and a fine grinding wheel is detachably connected to the other mounting groove. Mounting plates are fixedly connected to both ends of the base, and heat dissipation components are connected to the mounting plates. The heat dissipation components include a bucket-shaped cover and a drive shaft fixedly connected to the end of the cover away from the mounting plate. The cover and the mounting plate are connected by screws. A through hole is provided at the center of the drive shaft and the cover. An exhaust fan is installed at the opening of the through hole of the drive shaft. An exhaust groove with a conical cross-section is provided at the center of the mounting plate. A set of ventilation pipes is provided at both ends of the base. The ventilation pipes at both ends are connected to the exhaust groove at their respective ends, and the ends of the ventilation pipes away from the exhaust groove are connected to the corresponding mounting grooves.

[0007] Preferably, the surface of the coarse grinding wheel is coated with first diamond particles, and the surface of the fine grinding wheel is coated with second diamond particles. The particle size of the first diamond particles is larger than that of the second diamond particles, and the height of the protruding part of the first diamond particles is greater than that of the protruding part of the second diamond particles.

[0008] Using the above technical solution, the first diamond particle on the coarse grinding wheel performs coarse grinding. After the coarse grinding is completed, the item to be ground is moved to the fine grinding wheel, where the second diamond particle on the fine grinding wheel performs fine grinding.

[0009] Preferably, each group of ventilation ducts includes several air ducts disposed in the base. The air ducts of the same ventilation duct are conical in shape in the base, and one end of all air ducts of the same ventilation duct is connected to the air intake groove, and the other end is connected to the corresponding mounting groove.

[0010] With the above technical solution, when the base and the cover rotate, the exhaust fan works to introduce external air into the cover, and then enters the mounting groove through the air duct and multiple air channels, thereby dissipating heat from the corresponding coarse or fine grinding wheel and improving the heat dissipation effect.

[0011] Preferably, an annular honeycomb plate is fixed in the mounting groove, and the inner walls of the coarse grinding wheel and the fine grinding wheel are provided with mounting ears. The honeycomb plate and the mounting groove are provided with matching first screw holes, and the mounting ears are provided with second screw holes that match the first screw holes. The mounting ears are fixed to the honeycomb plate and the substrate by screws.

[0012] Through the above technical solution, after the air is introduced into the installation groove, it can be transmitted to most areas inside the coarse or fine grinding wheel through the honeycomb panel, further improving the heat dissipation efficiency.

[0013] Preferably, an annular box is fixed to the periphery of the end of the drive shaft away from the cover. A circuit board and a battery are installed inside the box, and a switch is provided outside the box. A battery cover is fastened to the box, and the fan, battery, switch and circuit board form a closed circuit.

[0014] Using the above technical solution, the exhaust fan can be turned on or off by toggling the switch, and the battery can be replaced by opening the battery cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) Both coarse grinding wheels and fine grinding wheels are installed on the base. After coarse grinding is completed, the item to be ground is moved to the fine grinding wheel and finely ground. The item is then finely ground by the fine grinding wheel. There is no need to replace the grinding wheel, so continuous coarse grinding and fine grinding can be achieved, which improves grinding efficiency.

[0017] (2) During grinding, the base and the cover rotate together, and the exhaust fans at both ends work to introduce external air into the cover, and then enter the mounting slot through the air duct and ventilation pipe, thereby dissipating heat from the corresponding coarse grinding wheel and fine grinding wheel. The air force of the exhaust fan is greater than that of the natural wind, thus improving the heat dissipation effect. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Example 1

[0023] Please see Figures 1-2 A diamond grinding wheel includes a cylindrical base 1 with two annular mounting grooves 2 on its outer wall. A coarse grinding wheel 3 is detachably connected to one groove 2, and a fine grinding wheel 4 is detachably connected to the other groove 2. The surface of the coarse grinding wheel 3 is coated with first diamond particles 11, and the surface of the fine grinding wheel 4 is coated with second diamond particles 12. The particle size of the first diamond particles 11 is larger than that of the second diamond particles 12, and the height of the protruding portion of the first diamond particles 11 is greater than the height of the protruding portion of the second diamond particles 12. Specifically, the particle size of the first diamond particles is 20-50 μm, and the particle size of the second diamond particles is 5-20 μm. During grinding, an object is fixed by a movable positioning device. First, the object is coarsely ground by the first diamond particles 11 on the coarse grinding wheel 3. After coarse grinding, the positioning device is driven to move horizontally, bringing the object into contact with the fine grinding wheel 3, where the object is finely ground by the second diamond particles 12 on the fine grinding wheel 3.

[0024] Mounting plates 5 are fixedly connected to both ends of the base 1, and heat dissipation components are connected to the mounting plates 5. The heat dissipation components include a funnel-shaped cover 6 and a drive shaft 7 fixedly connected to the end of the cover away from the mounting plate. The drive shaft 7 is provided with a spline groove for mounting a drive gear. The drive gear is driven to rotate by a motor, thereby driving the drive shaft 7 to rotate, which in turn drives the base 1 to rotate. The cover 6 and the mounting plate 5 are connected by screws. The center of the drive shaft 7 and the cover 6 is provided with a through hole 8. An exhaust fan 9 is installed at the opening of the through hole in the drive shaft 7. The center of the mounting plate 5 is provided with an exhaust groove 10 with a conical cross section. A set of ventilation pipes is provided at both ends of the base 1. The ventilation pipes at both ends are connected to the exhaust groove 10 at their respective ends. The end of the ventilation pipe away from the exhaust groove 10 is connected to the corresponding mounting groove 2. Each ventilation duct includes several air ducts 13 installed in the base 1. The air ducts 13 of the same ventilation duct are conical in shape in the base 1, and one end of all the air ducts 13 of the same ventilation duct is connected to the air duct 10, and the other end is connected to the corresponding mounting groove 2.

[0025] A ring-shaped box 16 is fixed to the outer periphery of the drive shaft 7 at the end furthest from the cover. A circuit board and battery are installed inside the box 16, and a switch 17 is located outside the box 16. A battery cover 18 is fastened to the box 16. The exhaust fan 9, battery, switch 17, and circuit board form a closed circuit. During polishing, the base 1 and cover 6 rotate together. Turning the switch 17 activates the exhaust fan, drawing external air into the cover. The air then flows through the air duct and multiple air channels into the corresponding mounting slots 2, thereby dissipating heat from the corresponding coarse polishing wheel 2 and fine polishing wheel 3, improving heat dissipation.

[0026] Example 2

[0027] Based on Embodiment 1, an annular honeycomb plate 14 is fixed inside the mounting groove 2. The inner walls of both the coarse grinding wheel 3 and the fine grinding wheel 4 are provided with mounting ears 15. The honeycomb plate 14 and the mounting groove 2 have matching first screw holes, and the mounting ears 15 have second screw holes that match the first screw holes. The mounting ears 15 are fixed to the honeycomb plate 14 and the substrate 1 by screws. The honeycomb plate 14 can be made of ceramic composite material. After air is introduced into the mounting groove 2, it can be transmitted through the honeycomb holes on the honeycomb plate 14 to most of the area inside the coarse grinding wheel 3 or the fine grinding wheel 4, increasing the heat dissipation area and further improving heat dissipation efficiency.
