[0002] Bearing rings are annular parts with raceways in rolling bearings, typically divided into inner and outer rings. They are the core components of the bearing that bear loads and guide the rolling elements. Inner ring: Usually fits tightly to the shaft and rotates with it; its outer surface has precision raceways. Outer ring: Usually installed in the bearing housing or housing bore to provide support; its inner surface has corresponding raceways. Special case: In thrust bearings, the rings are generally called "washers," the inner ring is called the shaft ring, and the outer ring is called the housing ring.

[0003] An existing high-precision automated grinding equipment for bearing rings typically requires manual clamping and fixing of the bearing rings before grinding.

[0013] The present invention has the following beneficial effects: When the motor of this invention is turned on, the output end drives the rotating rod to rotate. When the rotating rod rotates, it drives the rotating support plate to rotate inside the rotating support ring. The rotation of the rotating support plate will drive the bearing ring above to rotate together, so that the machine can fully perform the grinding work on the bearing ring. When the rotating support plate rotates, it will drive the second helical gear to rotate together. The second helical gear will mesh with the meshing gear to rotate on the surface of the support rod. When the meshing gear rotates, it will mesh with the first helical gear to rotate on the surface of the rotating support plate, so that the first helical gear and the rotating support plate rotate in opposite directions. When the first helical gear rotates, it drives the support plate to rotate together through the round rod. When the support plate rotates, it drives the long support frame to rotate together through the flexible rod and the telescopic rod, so that the cutting head device can perform the grinding work on the bearing ring above the rotating support plate. The cutting head device rotates in opposite directions to the workpiece, so that the machine can quickly grind the workpiece. At the same time, the workpiece squeezes the flexible rod, so that the cutting head device can fully perform the grinding work on workpieces of different sizes. The telescopic rod makes the cutting head device more stable during the grinding work.

[0014] When the second motor of this invention is turned on, the output end drives the fixed telescopic rod to rotate through the fixed plate. At this time, the fixed telescopic rod will drive the support ring plate and the elastic inclined plate to rotate on the surface of the long rod through the moving plate, so that the bearing rings on the surface of the support ring plate and the side support plate rotate, which facilitates the machine to grind the surface of the workpiece. At the same time, when the bidirectional electric push rod is turned on, the output end will drive the moving plate to move on the surface of the long rod. When the moving plate moves, it will drive the support ring plates to move closer or further apart. When the support ring plates move closer or further apart, they will drive the side support plates to move closer or further apart by squeezing the elastic inclined plate, so that the machine can fix bearing rings of different sizes. At the same time, the inner wall of the bearing ring is in contact with the surface of the support ring plate, so that the machine can avoid insufficient grinding due to the clamping position when grinding the workpiece.

[0015] When the circulating pump of this invention is turned on, the output end discharges the coolant from the coolant tank into the nozzle through the outlet pipe. This cools the bearing rings during grinding, preventing excessive temperature from affecting the quality of the finished workpiece. Simultaneously, when the second motor rotates, it drives the first pulley to rotate. The rotation of the first pulley drives the belt, which in turn drives the second pulley to rotate on the surface of the support frame. The rotation of the second pulley drives the second rotating rod to rotate as well, causing the second rotating rod to move the scraper. The scraper pushes the impurities above the filter plate, quickly separating the impurities from the coolant and preventing the filter plate from clogging due to impurity accumulation. The coolant that enters the circulating tank will be recycled through the circulation pipe, thus avoiding waste.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The circulating cleaning device 6 includes a coolant tank 60. The bottom of the coolant tank 60 is fixedly connected to the surface of the first helical gear 23. A support block 61 is fixedly connected to the surface of the coolant tank 60. A circulating pump 62 is fixedly connected to the inner wall of the support block 61. When the circulating pump 62 is turned on, the output end discharges the coolant inside the coolant tank 60 into the nozzle 65 through the water outlet pipe 63, thereby cooling the bearing rings during grinding through the nozzle 65. The output end of the circulating pump 62 is fixedly connected to the water outlet pipe 63. A water pipe bracket 64 is fixedly connected to the surface of the elongated support frame 28. The nozzle 65 is fixedly connected to the end of the water outlet pipe 63 away from the circulating pump 62. A filter plate 66 is fixedly connected to the inner wall of the collection tank 40. A circulating pipe 67 is fixedly connected to the inner wall of the collection tank 40. A limit telescopic rod is fixedly connected to the surface of the support ring frame 52. 68. A scraper 69 is fixedly connected to the end of the limiting telescopic rod 68 away from the support ring frame 52. A circulation box 70 is opened on the inner wall of the collection box 40. A threaded rod 71 is threadedly connected to the inner wall of the scraper 69. A first pulley 72 is fixedly connected to the output end of the second motor 42. When the first pulley 72 rotates, it will drive the belt 73 to drive the second pulley 74 to rotate on the surface of the support frame 41. The belt 73 is driven to the inner wall of the first pulley 72. The second pulley 74 is driven to the end of the belt 73 away from the first pulley 72. When the second pulley 74 rotates, it will drive the second rotating rod 75 to rotate together, so that the second rotating rod 75 drives the scraper 69 to move, so that the scraper 69 pushes the impurities above the filter plate 66. The second rotating rod 75 is fixedly connected to the surface of the second pulley 74.

[0028] The output end of the circulating pump 62 is fixedly connected to the inner wall of the coolant tank 60. The water outlet pipe 63 passes through the water pipe bracket 64 and extends to the inner wall of the nozzle 65.

The bottom of the support ring frame 52 is fixedly connected to the top of the filter plate 66. The inner wall of the second pulley 74 is rotatably connected to the surface of the support frame 41.

[0029] In operation, when the motor 20 is turned on, its output end drives the rotating rod 21 to rotate. The rotation of the rotating rod 21 causes the rotating support plate 22 to rotate inside the rotating support ring 30. The rotation of the rotating support plate 22 causes the upper bearing ring to rotate as well, allowing the machine to fully perform grinding work on the bearing ring. When the rotating support plate 22 rotates, it drives the second helical gear 31 to rotate as well. The second helical gear 31 meshes with the meshing gear 32, causing it to rotate on the surface of the support rod 2. When the meshing gear 32 rotates, it meshes with the first helical gear 23, causing it to rotate in the opposite direction to the rotating support plate 22. When the first helical gear 23 rotates, it drives the support plate 25 to rotate via the round rod 24. The rotation of the support plate 25, via the flexible rod... 26 and the telescopic rod 27 drive the long support frame 28 to rotate together, causing the cutter head device 29 to grind the bearing rings above the rotating support plate 22. The cutter head device 29 rotates in the opposite direction to the workpiece, allowing the machine to grind the workpiece quickly. At the same time, the workpiece squeezes the soft rod 26, allowing the cutter head device 29 to fully grind workpieces of different sizes. The telescopic rod 27 makes the cutter head device 29 more stable during grinding. When the second motor 42 is turned on, the output end drives the fixed telescopic rod 45 to rotate through the fixed plate 44. At this time, the fixed telescopic rod 45 will drive the support ring plate 47 and the elastic inclined plate 48 to rotate on the surface of the long rod 43 through the moving plate 46, causing the bearing rings on the surface of the support ring plate 47 and the side support plate 49 to rotate, facilitating the machine's rotation. The machine grinds the surface of the workpiece. Simultaneously, when the bidirectional electric actuator 54 is activated, its output end drives the moving plate 46 to move on the surface of the long rod 43. As the moving plate 46 moves, it causes the support ring plates 47 to move closer or further apart. When the support ring plates 47 move closer or further apart, they compress the elastic inclined plate 48, causing the side support plates 49 to move closer or further apart. This allows the machine to fix bearing rings of different sizes. At the same time, the inner wall of the bearing ring contacts the surface of the support ring plate 47, ensuring that the workpiece is not insufficiently ground due to the clamping position. When the circulating pump 62 is activated, its output end discharges the coolant from the coolant tank 60 into the nozzle 65 through the outlet pipe 63, thereby spraying the coolant onto the workpiece during grinding. The bearing rings are cooled to prevent overheating from affecting the quality of the finished product. Simultaneously, when the second motor 42 rotates, it drives the first pulley 72 to rotate. The rotation of the first pulley 72 drives the belt 73, which in turn drives the second pulley 74 to rotate on the surface of the support frame 41. The rotation of the second pulley 74 drives the second rotating rod 75 to rotate as well, thus moving the scraper 69. The scraper 69 pushes the impurities above the filter plate 66, quickly separating them from the coolant and preventing impurities from accumulating and clogging the filter plate 66. The coolant entering the circulation tank 70 is then recycled through the circulation pipe 67, preventing waste.
