Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding wheel technology, specifically to a composite grinding wheel grinding structure. Background Technology
[0002] A grinding wheel is an abrasive tool, typically made by bonding abrasive grains into a spherical shape with a bonding agent. It possesses a certain strength and performs a grinding function during high-speed rotation. While grinding wheels are inherently strong and capable of grinding most materials on the market, improper operation, such as impacts or prolonged exposure to high temperatures, can easily damage them, posing a safety hazard. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a composite grinding wheel structure, which solves the problem of grinding wheel damage caused by impacts or high temperatures during use.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a composite grinding wheel structure, including a wheel disk, a central mounting ring fixedly installed in the center of the wheel disk, two pairs of fan-shaped base plates installed on the wheel disk, fan-shaped grinding wheels respectively installed on the two pairs of fan-shaped base plates, an inner metal wire mesh provided inside the fan-shaped grinding wheel, an outer metal wire mesh provided inside the fan-shaped grinding wheel and on one side of the fan-shaped base plate, and a fixing mechanism provided on the fan-shaped base plate.
[0005] Preferably, the fixing mechanism includes fixing plates fixedly connected to the two side walls of the fan-shaped base plate, a pair of fixing plates fixedly connected to the wheel disc, and a gap is provided between the side walls of the two pairs of fan-shaped grinding wheels.
[0006] Preferably, a mounting hole is provided in the center of the central mounting ring.
[0007] Preferably, the thickness of the fixing plate is half the thickness of the fan-shaped base plate.
[0008] This utility model provides a composite grinding wheel structure, which has the following beneficial effects:
[0009] 1. The traditional one-piece disc grinding wheel is made into a grinding wheel composed of two pairs of sector grinding wheels. There is a gap between the two pairs of sector grinding wheels. During high-speed operation, the gap can meet the volume change caused by high temperature expansion. When the grinding wheel is subjected to external force, the two pairs of sector grinding wheels will usually only be damaged individually, and will not suddenly be damaged as a whole, which greatly reduces the situation of grinding wheel fragments flying.
[0010] 2. Metal wire mesh is installed inside and outside the grinding wheel to improve its strength and heat resistance, making it less prone to breakage, chipping, and cracking. It also increases the grinding wheel's explosion-proof performance and prevents it from exploding. Attached Figure Description

[0016] Both the wheel 1 and the center mounting ring 5 are existing mature components. The installation and use of the grinding wheel are common technical knowledge in the grinding wheel field, so there is no need to go into detail about the installation and use of the grinding wheel.
[0017] After two pairs of sector-shaped grinding wheels 2 are installed on the wheel disk 1, they form a concentric circle structure, and the gap 9 between them can meet the requirements of high temperature expansion.
[0018] Furthermore, the fixing mechanism includes fixing plates 3 fixedly connected to the two side walls of the fan-shaped base plate 6, a pair of fixing plates 3 fixedly connected to the wheel disc 1, and a gap 9 is provided between the side walls of the two pairs of fan-shaped grinding wheels 2.
[0019] Furthermore, a mounting hole 4 is provided in the center of the central mounting ring 5.
[0020] Furthermore, the thickness of the fixing plate 3 is half the thickness of the fan-shaped base plate 6.

The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0022] Example: In use, the fan-shaped grinding wheel 2 is responsible for grinding the material, while the inner and outer metal wire mesh 7 and 8 can improve the strength and heat resistance of the grinding wheel, making it less prone to breakage, chipping, or cracking. In addition, fixing wire mesh to the back and inside of the grinding wheel can increase its explosion-proof performance and prevent it from exploding.
