Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, and in particular to a dust collection device for CBN grinding wheel equipment. Background Technology

[0002] In the field of metal processing, grinding is a crucial process. It achieves precise dimensional control and improves surface finish by grinding the workpiece surface. With the continuous advancement of technology, traditional grinding wheel materials are gradually being replaced by more efficient and durable alternatives. Among them, CBN (cubic boron nitride) grinding wheels are an outstanding example. CBN grinding wheels exhibit exceptional performance in processing high-hardness materials such as hardened steel, alloy steel, and cemented carbide due to their excellent hardness, wear resistance, and thermal stability.

[0003] When using CBN grinding wheels for grinding, waste chips and dust are generated. The flying waste chips and dust can pollute the working environment and threaten the health of workers. Most existing grinding wheels are equipped with dust collection hoods and dust collection mechanisms, but lack cleaning mechanisms. Some dust is easily adsorbed on the inner wall of the dust collection hood due to static electricity, making it difficult to clean. Long-term accumulation of dust will affect the dust collection effect. Therefore, we propose a dust collection device for CBN grinding wheel grinding equipment. Utility Model Content

Dust collection hoods 3 are provided at both the front and rear ends of the grinding machine body 2. The dust collection hoods 3 are connected to a vacuum cleaner via a flexible hose, which can suck up the waste chips and dust generated during grinding and prevent dust from splashing. Fixed disks 10 are fixedly installed on the facing surfaces of the two sets of dust collection hoods 3. Fixed shafts 14 are fixedly connected to the inner walls of the fixed disks 10. The fixed disks 10 and fixed shafts 14 provide support for the dust collection hoods 3. A guide groove 6 is opened at the front end of the fixed shaft 14 and is located inside the dust collection hoods 3. Rotating shafts 13 are rotatably connected to the separating surfaces of the two sets of dust collection hoods 3. A worm gear 8 is fixedly installed at the front end of the rotating shaft 13. When the worm gear 8 rotates, it drives the rotating shaft 13 to rotate. A scraper 12 is fixedly connected to the rear end of the rotating shaft 13 and is movably connected to the inner wall of the dust collection hood 3. The scraper 12 and the dust collection hood 3 are connected in a specific manner. The inner wall is tightly attached, so that when the scraper 12 moves, the dust and debris adsorbed on the inner wall of the dust collection hood 3 can be scraped off. A guide block 16 is fixedly installed at the tail end of the scraper 12. The guide block 16 is slidably engaged with the inner wall of the guide groove 6. When the scraper 12 moves, it will drive the guide block 16 to slide along the trajectory of the guide groove 6. Servo motors 5 are provided on the disjoint surfaces of the two sets of dust collection hoods 3. The output end of the servo motor 5 is fixedly connected to the worm 7, and the worm 7 and the worm wheel 8 mesh with each other. The servo motor 5 provides power for the rotation of the worm 7. After the servo motor 5 is powered on, its output end will drive the worm 7 to rotate, and then drive the worm wheel 8 to rotate. A dust collection box 4 is fixedly installed at the bottom of the two sets of dust collection hoods 3. An opening 11 is opened on the inner wall of the two sets of dust collection hoods 3, and the dust collection hood 3 is connected to the inside of the dust collection box 4 through the opening 11. The debris and dust scraped off by the scraper 12 will fall into the dust collection box 4 through the opening 11 for collection.

[0021] Two sets of fixed shafts 14 are fixedly connected to the front and rear ends of the grinding machine body 2, respectively. The rear end of the rotating shaft 13 extends movably into the interior of the dust collection hood 3, and the worm gear 8 is located on the outside of the dust collection hood 3. The inner walls of both sets of fixed shafts 14 are rotatably connected to drive shafts 15, and the drive shafts 15 are fixedly connected to the drive mechanism inside the grinding machine body 2. The front end of the drive shaft 15 extends into the interior of the dust collection hood 3. The front end of the drive shaft 15 is fixedly connected to a grinding wheel 9, and the grinding wheel 9 is located inside the dust collection hood 3. After the drive mechanism inside the grinding machine body 2 drives the drive shaft 15 to rotate, the drive shaft 15 will drive the grinding wheel 9 to rotate, thereby performing the grinding work. Two sets of support plates 17 are fixedly installed on the separating surfaces of the two sets of dust collection hoods 3, and the front end of the worm gear 7 is rotatably connected to the bottom of one set of support plates 17. The top of the other set of support plates 17 is fixedly connected to the bottom of the servo motor 5. The support plate 17 provides support for the servo motor 5 and the worm gear 7.

[0022] It should be noted that this utility model is a dust collection device for CBN grinding wheel equipment. In use, the dust collection hood 3 is connected to a vacuum cleaner via a hose. The power is turned on to start the drive mechanism inside the grinding machine body 2, causing the drive shaft 15 to rotate, which in turn drives the grinding wheel 9 to rotate. The worker can then begin grinding. Simultaneously, the vacuum cleaner is activated, and the waste chips and dust generated during grinding are sucked into the dust collection hood 3, and then enter the vacuum cleaner through the hose, reducing the risk of workers inhaling harmful dust. After grinding is completed, some of the waste chips and dust are discharged due to… Static electricity will adhere to the inner wall of the dust collection hood 3. At this time, the servo motor 5 is controlled to rotate, so that its output end drives the worm gear 7 to rotate, which in turn drives the worm wheel 8 to rotate. The worm wheel 8 is fixedly connected to the rotating shaft 13, and the rotating shaft 13 is fixedly connected to the scraper 12. When the worm wheel 8 rotates, it drives the scraper 12 to rotate along the inner wall of the dust collection hood 3, thereby scraping off the dust adsorbed on the inner wall of the dust collection hood 3, avoiding the accumulation of dust and affecting the dust collection effect. Under the push of the scraper 12, the dust falls into the dust collection box 4 below for collection.
