[0001] The present application relates to the field of burr cleaning, and particularly to a burr cleaning device for the outer surface of a bearing ring. Background Art

[0002] A bearing ring is an annular part of a radial rolling bearing with one or several raceways. In the process of production and processing of existing bearing rings, burrs exist on the outer wall of the bearing ring, so it is necessary to clean the burrs on the outer ring of the bearing, and thus it is necessary to use a corresponding burr cleaning device. Most of the existing burr cleaning devices are composed of a motor and a grinding roller. The motor drives the grinding roller to grind the outer wall of the positioned bearing ring to remove burrs. However, in the actual use process, the positioning of the bearing ring does not have adjustability and cannot adapt to the obstacle-free positioning of bearing rings of different sizes. Moreover, most of them can only clean the burrs of bearing rings one by one, resulting in low work efficiency. Utility Model Content

Detailed Embodiment

[0017] The following further elaborates on the present application in conjunction with the attached Figures 1-3 drawings.

[0018] An embodiment of the present application discloses a device for deburring the outer surface of a bearing race. Refer to Figure 1, including a lower rectangular frame 1. Columns 7 are fixedly provided at the four corners of the bottom surface of the lower rectangular frame 1. Two rectangular plates 8 are fixedly provided on both side walls of the lower rectangular frame 1. Guide rods 13 are fixedly provided on the top surface of each rectangular plate 8. A limiting plate 12 is fixedly provided on the top surface of the guide rod 13. A connecting plate 9 is also sleeved on the outer wall of the guide rod 13. An upper rectangular frame 14 is fixedly provided between the four connecting plates 9. A rectangular block 5 is provided between the two rectangular plates 8. The rectangular block 5 is fixedly connected to the lower rectangular frame 1. A hydraulic cylinder 4 is fixedly provided on the bottom surface of the rectangular block 5. The output end of the hydraulic cylinder 4 penetrates through the rectangular block 5 and extends upward to be fixedly connected to a connecting block 6. The connecting block 6 is fixedly connected to the upper rectangular frame 14. By simultaneously driving the two connecting blocks 6 to move vertically downward through the output ends of the two hydraulic cylinders 4, the vertical downward movement of the connecting blocks 6 drives the upper rectangular frame 14 and the connecting plates 9 to move downward along the vertical direction of the guide rods 13. The downward movement of the upper rectangular frame 14 drives the second roller 10 and the grinding roller 11 to move downward. Place the bearings between the two first rollers 3 in sequence. By adjusting the heights of the second roller 10 and the grinding roller 11, bearings of different sizes can be fixedly limited, preventing the grinding roller 11 from displacing when cleaning the burrs on the outer wall of the bearing, thereby improving the working accuracy of the device.

[0019] Refer to Figures 1-3 , a cleaning component is provided between the upper rectangular frame 14 and the lower rectangular frame 1. There are three groups of cleaning components, which are horizontally and equidistantly distributed. The cleaning component includes first rollers 3, second rollers 10, and grinding rollers 11. There are two first rollers 3, which are arranged inside the lower rectangular frame 1. Shaft rods 15 are fixedly penetrated inside the two first rollers 3. Both ends of the shaft rods 15 are rotatably connected to the lower rectangular frame 1. One end of each shaft rod 15 penetrates through the lower rectangular frame 1 and extends outward to be fixedly sleeved with a sprocket 2. The six sprockets 2 are driven by a chain. The other end of the outermost shaft rod 15 penetrates through the lower rectangular frame 1 and extends outward to be connected to the output end of a motor 16. The second rollers 10 and the grinding rollers 11 are arranged inside the upper rectangular frame 14. The second rollers 10 and the grinding rollers 11 are arranged horizontally and parallel to each other. Shafts are penetrated inside the second rollers 10 and the grinding rollers 11. The shafts on the second rollers 10 are movably connected to the second rollers 10. The shafts on the grinding rollers 11 are rotatably connected to the grinding rollers 11. Both ends of the shafts are connected to the upper rectangular frame 14. By driving the shaft rod 15 thereon to rotate through the output end of the motor 16, the rotation of the shaft rod 15 drives the sprocket 2 thereon to rotate. Since the six sprockets 2 are driven by a chain, that is, the six sprockets 2 simultaneously drive the six shaft rods 15 to rotate. The rotation of the six shaft rods 15 drives the six first rollers 3 to rotate. The rotation of the first rollers 3 drives the bearings thereon to rotate in a circle. At the same time, in cooperation with the grinding rollers 11, it is possible to simultaneously perform comprehensive burr cleaning on the outer walls of multiple bearings.

[0020] The implementation principle of a burr cleaning device for the outer surface of a bearing ring in an embodiment of the present application is as follows: During use, the output ends of two hydraulic cylinders 4 simultaneously drive two connecting blocks 6 to move vertically downward. The vertical downward movement of the connecting blocks 6 drives the upper rectangular frame 14 and the connecting plate 9 to move downward along the vertical direction of the guide rod 13. The downward movement of the upper rectangular frame 14 drives the second roller 10 and the grinding roller 11 to move downward. Place the bearings in sequence between the two first rollers 3. By adjusting the heights of the second roller 10 and the grinding roller 11, bearings of different sizes can be fixedly limited. Then, the output end of the motor 16 drives the shaft rod 15 thereon to rotate. The rotation of the shaft rod 15 drives the sprocket 2 thereon to rotate. Since the six sprockets 2 are driven by chain transmission, that is, the six sprockets 2 simultaneously drive the six shaft rods 15 to rotate. The rotation of the six shaft rods 15 drives the six first rollers 3 to rotate. The rotation of the first rollers 3 drives the bearings thereon to rotate circumferentially. At the same time, in cooperation with the grinding roller 11, it is possible to simultaneously perform all-round burr cleaning on the outer walls of multiple bearings.
