[0002] A grinding wheel is a tool used for material processing. It is usually made of a mixture of abrasive particles and a binder. Grinding wheels can grind glass to remove excess material from the glass surface to achieve the required dimensional accuracy and surface roughness. Grinding wheels come in a variety of shapes and sizes, with common shapes including round and conical.

[0003] Currently, grinding wheels are often connected to the rotating shaft using a simple key connection. However, when processing glass at high speeds, the grinding wheel body may become loose due to centrifugal force and other factors, leading to a decrease in processing accuracy. Furthermore, grinding wheels are prone to wear during use and require frequent replacement. However, current grinding wheel devices often use welding or riveting to fix them to the rotating shaft, making the replacement process quite complicated. Therefore, a new grinding wheel for glass processing is proposed to solve the problems mentioned above. Utility Model Content

[0013] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0014] Reference Figures 1-5 The image shows a grinding wheel for glass processing, comprising a grinding wheel body 1, a sanding ring 2, and a rotating shaft 3. The sanding ring 2 is fixedly connected to the lower end of the grinding wheel body 1. Multiple grooves 4 are formed through the lower end of the sanding ring 2. During use, a drive device rotates the grinding wheel body 1 and the sanding ring 2 at high speed via the rotating shaft 3. The lower end of the sanding ring 2 contacts the glass workpiece for cutting and grinding. Grinding debris generated during grinding is discharged through the grooves 4, preventing debris accumulation and scratches on the glass. An upper flange 5 is provided above the grinding wheel body 1, with multiple upper connecting holes 6 formed through its upper surface. A lower flange 7 is provided inside the grinding wheel body 1. Multiple centrifugal channels 14 are formed through the inner wall of the grinding wheel body 1 below the lower flange 7. The centrifugal channels 14 are inclined radial through holes, evenly distributed along the circumference of the grinding wheel body 1. When the grinding wheel body 1 rotates, the centrifugal channels 14 on its inner side generate centrifugal force, thereby guiding coolant and debris outwards, keeping the processing area clean. The lower end of the rotating shaft 3 is fixedly connected to the center of the lower flange 7. The lower flange 7 has multiple lower connecting holes 8 through its bottom end. The upper connecting hole 6 is threaded with bolts 9. The upper flange 5 and the lower flange 7 are bolted together to firmly fix the grinding wheel body 1 to the rotating shaft 3, effectively preventing the grinding wheel body 1 from loosening due to centrifugal force during high-speed rotation, thus ensuring the stability of the processing. The lower end of bolts 9 passes through the top end of the grinding wheel body 1 and is threaded to the inner wall of the lower connecting holes 8. The center of the grinding wheel body 1 has a through hole 10, and the center of the upper flange 5 has a through hole 11. The outer surface of the rotating shaft 3 is slidably connected to the inner walls of the through holes 10 and 11. The outer surface of the rotating shaft 3 is slidably connected to the upper flange 5 above the upper flange 5. The fixed shaft 12 is provided with a snap-fit ​​assembly 13 inside the fixed shaft 12. The grinding wheel can be quickly fixed and released by rotating the handle 1307 using the snap-fit ​​assembly 13, reducing the time required to replace the grinding wheel and improving the operating efficiency of the equipment. The snap-fit ​​assembly 13 includes a fixing plate 1301, which is fixedly connected to the top end of the fixing shaft 12. Two snap-fit ​​blocks 1302 are fixedly connected to the top end of the rotating shaft 3. A rectangular groove 1303 is formed at the top end of the fixing shaft 12. Two fixing blocks 1304 are arranged inside the rectangular groove 1303. Limiting holes 1305 are formed through the interior of each fixing block 1304, corresponding to the snap-fit ​​blocks 1302. A drive rod 1306 is rotatably connected to the front end of each fixing block 1304. The other end of the drive rod 1306 passes through the inner surface of the fixing shaft 12 and is fixedly connected to a handle 1307. The other end of the drive rod 1306 is threaded into the interior of the fixing shaft 12. A spring 1308 is fixedly connected to the rear end of each fixing block 1304. The other end of the spring 1308 is fixedly connected to the inner wall of the rectangular groove 1303. When the grinding wheel needs to be replaced, the drive rod 1306 is moved by rotating the handle 1307 in the reverse direction. Spring 1308 pushes the fixing block 1304 to release the locking block 1302, thus no longer fixing the rotating shaft 3. At this time, the rotating shaft 3 can be rotated and removed. Then, the upper flange 5, grinding wheel body 1 and lower flange 7 are separated by unscrewing bolt 9. The top of the rotating shaft 3 is fixedly connected to guide rods 1309 at both the front and rear of the locking block 1302. The bottom of the fixing plate 1301 is fixedly connected to two guide posts 1310. The guide rods 1309 and guide posts 1310 are set accordingly. When changing the grinding wheel, the rotating shaft 3 is inserted into the fixed shaft 12. The insertion stops when the top of the locking block 1302 at the upper end of the rotating shaft 3 contacts the bottom end of the fixing plate 1301. At this time, the rotating shaft 3 is rotated so that the guide posts 1310 and guide rods 1309 cooperate. At this time, the rotating shaft 3 reaches the designated position. At the same time, rotating the handle 1307 drives the fixing block 1304 connected to the drive rod 1306 to move and engage with the locking block 1302, thus completing the fixing of the rotating shaft 3.

[0015] The usage process of this utility model is as follows: First, the drive equipment drives the grinding wheel body 1 and the sand ring 2 to rotate at high speed through the rotating shaft 3. The lower end of the sand ring 2 contacts the glass workpiece for cutting and grinding. The grinding debris generated during the grinding process is discharged through the groove 4 to prevent the accumulation of grinding debris from scratching the glass. When it is necessary to replace the grinding wheel, the handle 1307 is rotated in the opposite direction to drive the rod 1306 to move. The spring 1308 pushes the fixing block 1304 to release the locking block 1302, so that the rotating shaft 3 is no longer fixed. At this time, the rotating shaft 3 can be rotated off. Then, the upper flange 5, the grinding wheel body 1 and the lower flange 7 are separated by unscrewing the bolt 9 for cleaning or replacement.

[0016] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
