Description

Technical Field

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

[0002] The grinding wheel of a grinding machine is a key tool in grinding processes used to remove material from a workpiece. It achieves precise material removal by contacting the workpiece through high-speed rotation. The grinding wheel is typically composed of abrasive, bonding agent, and pores. The abrasive is the hard particle used to cut the workpiece, the bonding agent binds the abrasive particles together, and the pores help with cooling and chip removal during the grinding process.

[0003] CNC grinding machines frequently require the replacement of grinding wheels of varying thicknesses. Common grinding wheel fixing devices rely on mechanical clamping to secure the grinding wheel. However, if the fixing part wears down after prolonged use, it can become uneven, making it impossible to secure the grinding wheel. This can lead to wheel misalignment and vibration during use. Furthermore, common grinding wheel assemblies cannot recycle the wastewater from cooling processes, requiring a continuous water supply and wasting water resources. Therefore, a new grinding wheel assembly for CNC grinding machines is needed to meet these requirements. Utility Model Content

[0004] The purpose of this invention is to provide a grinding wheel assembly for a CNC grinding machine to solve the problems mentioned in the background art.

[0024] To achieve the function of fixing the grinding wheel, the mounting device 2 includes a rotating shaft block 21, which is mounted on the first rotating shaft 7. A protective cover fixing block 20 is installed around the rotating shaft block 21 and is fixedly installed on one side of the grinding wheel housing 1. A grinding wheel fixing block 23 is installed on one side of the rotating shaft block 21. The first grinding wheel 4 is installed between the rotating shaft block 21 and the grinding wheel fixing block 23. The rotating shaft block 21 has a groove on the side near the first grinding wheel 4, and a first sealing ring 22 is installed in the groove. The grinding wheel fixing block 23 has a groove on the side near the first grinding wheel 4, and a second sealing ring 24 is installed in the groove. The protective cover fixing block 20 has a chip removal groove 25 on the side near the grinding wheel fixing block 23. A protective cover 5 is installed on the protective cover fixing block 20 and is installed above the first grinding wheel 4. In use, the first motor 6 is installed on the grinding wheel. Inside the gearbox 1, the first grinding wheel 4 is mounted on the first rotating shaft 7. The first motor 6 drives the first rotating shaft 7 to rotate, thereby driving the first grinding wheel 4 to rotate. The first grinding wheel 4 is used to grind the workpiece. By installing sealing rings on the side of the rotating shaft block 21 and the grinding wheel fixing block 23 near the first grinding wheel 4, when the surface of the grinding wheel becomes uneven after long-term use, the first sealing ring 22 and the second sealing ring 24 can press the first grinding wheel 4 flat, so that the first grinding wheel 4 keeps the center vertical during operation and avoids shaking. During installation, first put the first grinding wheel 4 onto the first rotating shaft 7, then press the side of the grinding wheel fixing block 23 with the second sealing ring 24 against the first grinding wheel 4 and screw it into the first rotating shaft 7, and tighten the grinding wheel fixing block 23. At this time, the first grinding wheel 4 is fixed on the first rotating shaft 7.

[0025] Example 2: As Figure 1-3 To achieve the functions of cooling the grinding wheel and recycling water resources, the cooling device 3 includes a water tank 30, which is installed below the grinding wheel housing 1. A water pump 31 is installed inside the water tank 30, and a water pump pipe 32 is installed on the water pump 31.

The protective cover 5 can intercept some of the liquid. The liquid falls into the water tank 30 along the protective cover 5. The interception net 35 on the water tank 30 can intercept the debris generated during large-particle grinding. The wastewater containing small impurities is then filtered through the filter cotton 34 to prevent the water pump 31 from sucking in impurities and causing blockage. The remaining features are the same as in Embodiment 1.

[0026] The working principle is as follows: During use, the first motor 6 is installed inside the grinding wheel housing 1, and the first grinding wheel 4 is installed on the first rotating shaft 7. The first motor 6 drives the first rotating shaft 7 to rotate, thereby driving the first grinding wheel 4 to rotate. The first grinding wheel 4 grinds the workpiece. By installing sealing rings on the rotating shaft block 21 and the grinding wheel fixing block 23 near the first grinding wheel 4, when the surface of the grinding wheel becomes uneven after prolonged use, the first sealing ring 22 and the second sealing ring 24 can press the first grinding wheel 4 flat, ensuring that the first grinding wheel 4 remains vertically centered during operation and preventing wobbling. During installation, first, the first grinding wheel 4 is fitted onto the first rotating shaft 7, and then the grinding wheel fixing block 23 is installed. The side with the second sealing ring 24 is screwed tightly onto the first grinding wheel 4 and screwed into the first rotating shaft 7. The grinding wheel fixing block 23 is then tightened, and the first grinding wheel 4 is fixed on the first rotating shaft 7. During operation, cooling liquid is stored in the water tank 30 and pumped into the water pump pipe 32 through the water tank 30. The liquid is then sprayed out through the external water pipe 33, which will cool the first grinding wheel 4 below. When the first grinding wheel 4 rotates, the liquid will splash. The protective cover 5 can intercept some of the liquid, and the liquid falls into the water tank 30 along the protective cover 5. The interception net 35 on the water tank 30 can intercept the large particles of debris generated during grinding. The wastewater containing small impurities is then filtered through the filter cotton 34 to prevent the water pump 31 from sucking in impurities and causing blockage.
