Description

Technical Field

[0001] This utility model relates to the field of blade sharpening technology, and in particular to a blade fine grinding wheel adjustment mechanism. Background Technology

[0002] In metal processing, precision manufacturing, and many industrial fields, precision grinding wheels are widely used for precision grinding of metal workpieces such as cutting tools and molds. With their high precision and high efficiency, these grinding wheels have become an indispensable tool in modern industry.

[0003] Traditional precision grinding wheel adjustment mechanisms for cutting tools, while capable of precise adjustment between the grinding wheel and the cutting tool to ensure grinding quality, suffer from several drawbacks during long-term use. Grinding shavings and metal powder easily adhere to the surface and pores of the grinding wheel, altering its surface morphology and grinding performance. Residual grinding shavings and metal powder embed in the working layer of the grinding wheel, disrupting its original grain size distribution and reducing grinding precision. This leads to increased deviations in the cutting edge size and surface roughness of the finished cutting tool, accelerating wheel wear and shortening its lifespan. Therefore, we propose a precision grinding wheel adjustment mechanism for cutting tools. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a tool fine grinding wheel adjustment mechanism. This mechanism can solve the problem that although traditional tool fine grinding wheel adjustment mechanisms can achieve precise adjustment between the grinding wheel and the tool to ensure the quality of grinding, during long-term use, grinding debris and metal powder are very easy to adhere to the surface and pores of the grinding wheel. The attached impurities will change the morphology of the grinding wheel surface and the grinding performance. The residual grinding debris and metal powder will embed into the working layer of the grinding wheel, destroy its original particle size distribution, reduce the grinding accuracy, and lead to increased deviation of the cutting edge size and increased surface roughness of the processed tool, thereby accelerating the wear of the grinding wheel and shortening its service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blade fine grinding wheel adjustment mechanism, comprising:

[0006] The system includes a fine grinding mechanism, a coarse grinding mechanism, and a fine grinding wheel mechanism. The fine grinding mechanism is located on one side of the coarse grinding mechanism, and the fine grinding wheel mechanism is located on the fine grinding mechanism.

The output ends of the two drive motors rotatably extend into the inside of the corresponding lifting frames and are fixedly connected to the corresponding cleaning brush cylinders. Multiple dust suction ports are opened on the outer surface of the two cleaning brush cylinders.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a blade fine grinding wheel adjustment mechanism, comprising:

[0028] The fine grinding mechanism 2, the coarse grinding mechanism 1, and the fine grinding wheel mechanism 3 are provided. The fine grinding mechanism 2 is located on one side of the coarse grinding mechanism 1, and the fine grinding wheel mechanism 3 is located on the fine grinding mechanism 2.

[0029] The grinding wheel cleaning structure is located on the fine grinding mechanism 2;

[0030] The grinding wheel cleaning structure includes a cleaning box 4, two electric telescopic rods 11, two lifting frames 6, two cleaning brush cylinders 12, and two drive motors 5. The cleaning box 4 is fixedly connected to the fine grinding mechanism 2. The two electric telescopic rods 11 are fixedly installed inside the cleaning box 4. The telescopic ends of the two electric telescopic rods 11 slide to the bottom of the cleaning box 4 and are fixedly connected to the corresponding lifting frames 6. The two lifting frames 6 are both "C" shaped. The two cleaning brush cylinders 12 are rotatably connected to the inside of the corresponding lifting frames 6. The two drive motors 5 are fixedly installed on one side of the corresponding lifting frames 6. The output ends of the two drive motors 5 rotatably extend into the inside of the corresponding lifting frames 6 and are fixedly connected to the corresponding cleaning brush cylinders 12. Multiple dust suction ports 16 are opened on the outer surface of the two cleaning brush cylinders 12.

[0031] The grinding wheel cleaning structure also includes two hoses 13, two connecting square tubes 14, two rotating tubes 15, a sealing box 9, and an exhaust fan 7. The sealing box 9 is fixedly connected inside the cleaning box 4. The two rotating tubes 15 are both fixedly connected to the side of the corresponding cleaning brush cylinder 12 away from the corresponding drive motor 5. The two connecting square tubes 14 are both fixedly connected to the side of the corresponding lifting frame 6 away from the drive motor 5. The ends of the two rotating tubes 15 away from the corresponding cleaning brush cylinder 12 extend to the outside of the corresponding lifting frame 6 and communicate with the inside of the corresponding connecting square tube 14. One end of each of the two hoses 13 communicates with the inside of the corresponding connecting square tube 14. The ends of the two hoses 13 away from the corresponding connecting square tube 14 communicate with the inside of the sealing box 9. The exhaust fan 7 is fixedly installed on the side of the cleaning box 4 away from the coarse grinding mechanism 1.

[0032] The exhaust end of the exhaust fan 7 extends into the interior of the cleaning box 4 and communicates with the interior of the sealing box 9. A filter cover 8 is installed on the exhaust end of the exhaust fan 7. A collection box 10 is slidably connected inside the cleaning box 4. One side of the collection box 10 slidably extends into the interior of the sealing box 9.

[0033] Both rotating tubes 15 are connected to the interior of the corresponding cleaning brush cylinder 12, and multiple bristles are fixedly connected to the outer surface of both cleaning brush cylinders 12.

[0034] Furthermore, when using this device, when it is necessary to clean the fine grinding wheel, the electric telescopic rod 11 is activated, and its telescopic end drives the lifting frame 6 to descend, so that the cleaning brush cylinder 12 approaches and contacts the surface of the fine grinding wheel. Subsequently, the drive motor 5 is started, driving the cleaning brush cylinder 12 to rotate. The bristles on the outer surface of the brush cylinder mechanically clean the surface of the grinding wheel, removing the attached grinding debris, metal powder and other impurities.

[0035] During the cleaning process, the exhaust fan 7 starts simultaneously, creating a negative pressure inside the sealed box 9. This negative pressure is transmitted through the hose 13, connecting square tube 14, and rotating tube 15 to the inside of the cleaning brush cylinder 12, causing the suction port 16 to generate suction, which draws the impurities swept off by the brush into the brush cylinder. The impurities are then transported to the sealed box 9 through the rotating tube 15, connecting square tube 14, and hose 13. The impurities are intercepted by the filter cover 8 and fall into the collection box 10 for centralized collection. The filtered air is discharged through the exhaust fan 7. After cleaning is completed, the electric telescopic rod 11 retracts, driving the lifting frame 6 and the cleaning brush cylinder 12 to rise and reset. The operator can periodically remove the collection box 10 to clean the impurities inside. A sealing gasket is provided at the sliding connection between the collection box 10 and the cleaning box 4.

[0036] Through the combined action of mechanical cleaning by the cleaning brush cylinder 12 and negative pressure adsorption by the dust suction port 16, the grinding debris and metal powder in the surface and pores of the grinding wheel can be effectively removed, preventing premature failure of the grinding wheel due to wear caused by foreign objects, keeping the equipment in a stable operating state, reducing equipment debugging time and maintenance frequency due to decreased precision, and further improving the service life of the grinding wheel.
