Description

Technical Field

[0001] This invention belongs to the technical field of bearing processing equipment, specifically a bearing inner ring grinding device. Background Technology

[0002] Stainless steel bearings possess properties such as corrosion resistance, high temperature resistance, and high strength, making them widely used in humid or corrosive environments such as food processing, medical equipment, and chemical equipment. Grinding the inner wall of stainless steel bearings is a key step in the manufacturing process. Grinding can reduce the surface roughness of the inner wall, and a smooth inner wall can reduce the retention of contaminants such as dust and metal shavings, avoiding wear or sticking wear caused by impurities.

[0003] A patent application with publication number CN117697623B discloses a grinding head, method, and grinding device for use on the inner wall of the outer ring of a bearing. The grinding device also has a bearing clamping seat, in which upper and lower sliders are provided along the longitudinal direction. A pressure rod is slidably connected to the upper and lower sliders along the transverse direction. An upper pressure head is fixed to the inner side of the pressure rod.

[0011] Preferably, a magnetic block is slidably connected inside the second turntable, a pressing block is fixedly connected to one side of the magnetic block, a moving rod is slidably connected to one side of the pressing block, one end of the moving rod is fixedly connected to one side of the clamping plate, and a second elastic telescopic rod is fixedly connected to the inner lower surface of the second turntable, with the telescopic end of the second elastic telescopic rod slidably connected to the inside of the magnetic block.

[0012] Preferably, a fixing plate is fixedly connected to one side of the second support frame, and an electromagnet is fixedly connected to the inner wall of the fixing plate. When energized, the magnetism of the electromagnet and the magnetism of the magnetic block repel each other.

[0013] Preferably, the side wall of the clamping plate is rotatably connected to a roller, and the inner wall of the second turntable is fixedly connected to a limit frame, wherein the inner wall of the limit frame and the surface of the roller are slidably connected.

[0014] Preferably, the inner lower surface of the fixing plate is fixedly connected with a plurality of protrusions, and the upper surface of the clamping plate is fixedly connected with a pressing rod.

[0015] Preferably, a movable plate is slidably connected inside the base plate, and a filter tube is fixedly connected inside the movable plate. A filter screen is provided at one end of the filter tube, and a discharge valve is provided at the other end of the filter tube.

[0016] Preferably, a first elastic telescopic rod is fixedly connected to the lower surface of the base plate, and the telescopic end of the first elastic telescopic rod is fixedly connected to the lower surface of the movable plate.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The bearing inner ring grinding device of the present invention includes a clamping plate. When the second turntable moves the bearing to the grinding mechanism, the electromagnet is energized. The second turntable moves the magnetic block directly below the electromagnet. At this time, the electromagnet generates a repulsive force on the magnetic block, causing the magnetic block to descend and drive the pressing block to push the moving rod. The moving rod pushes the clamping plate towards the outer wall of the bearing, clamping the outer wall of the bearing. At the same time, the lateral end of the clamping plate is on the upper surface of the outer wall of the bearing. Then, the turntable and the grinding roller are driven to rotate. The grinding roller and the inner wall of the bearing are in contact for grinding. The turntable drives the lever to rotate, and the lever rotates and moves the lateral end of the clamping plate, so that the clamping plate drives the second turntable and the bearing to rotate synchronously. The rotation direction of the bearing is opposite to that of the grinding roller, thus grinding the inner wall of the bearing. This device uses the reverse rotation of the bearing to make the grinding roller contact the inner wall of the bearing more fully, avoiding local over-grinding or under-grinding caused by unidirectional rotation, thereby improving the grinding effect.

[0019] 2. The bearing inner ring grinding device of the present invention, through the protrusion, when the lateral end of the clamping plate moves to the upper surface of the bearing and the clamping plate rotates, the clamping plate drives the pressing rod to rotate. After the pressing rod contacts the protrusion, the pressing rod pushes the clamping plate downward. The clamping plate drives the bearing downward through the lateral end and presses the moving plate. When the pressing rod disengages from the protrusion, the moving plate drives the bearing to reset. This process is repeated, so that when grinding the inner wall of the bearing, the bearing can be driven to reciprocate, which can shake off the grinding debris attached to the inner wall of the bearing. The debris is then collected in the filter tube through the filter screen inside the moving plate. This device can shake off the grinding debris attached to the inner wall of the tube, avoiding the problem of the debris contacting the grinding roller and causing scratches on the inner wall. At the same time, it can also prevent the debris from spreading and reduce the problem of secondary pollution. Attached Figure Description

Detailed Implementation

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example 1: As Figures 1 to 11 As shown in the figure, a bearing inner ring grinding device according to an embodiment of the present invention includes a base plate 1. A first support frame 11 is fixedly connected to the upper surface of the base plate 1. A material feeder 12 is fixedly connected inside the first support frame 11. A first turntable 4 is rotatably connected to the upper surface of the base plate 1. A second turntable 5 is rotatably connected inside the first turntable 4. A clamping plate 53 is slidably connected inside the second turntable 5. The clamping plate 53 includes a transverse end 531. A grinding mechanism 2 is provided on the upper surface of the base plate 1. The grinding mechanism 2 includes a housing 22. A rotating plate 23 is rotatably connected inside the housing 22. A lever 231 is fixedly connected to the lower surface of the rotating plate 23. A grinding roller 26 is rotatably connected to the lower surface of the housing 22. The grinding roller 26 and the rotating plate 23 rotate in opposite directions. A discharge port 14 is fixedly connected inside the base plate 1.

[0035] Specifically, existing bearing inner ring grinding devices typically use a clamp to fix the bearing, and then use a grinding roller 26 to grind the inner wall of the bearing. Since the bearing is fixed, if the grinding roller 26 stays in the area for a long time, it can cause local over-grinding or under-grinding of the bearing.

[0036] To avoid the aforementioned technical problems, this device operates as follows: When using this device, the bearing body 6 in the unloading rack 12 falls into the second turntable 5 inside the first turntable 4. The first turntable 4 is then driven to rotate intermittently, causing the bearing body 6 inside the second turntable 5 to rotate synchronously. When the bearing body 6 rotates to the grinding mechanism 2, the clamping plate 53 inside the second turntable 5 is driven to slide towards the outer wall of the bearing body 6. The clamping plate 53 contacts the outer wall of the bearing body 6 and clamps it. Simultaneously, the lateral end 531 of the clamping plate 53 is positioned on the upper surface of the bearing body 6. Then, the grinding roller 26 and the turntable 23 are driven... The grinding roller 26 and the rotating plate 23 rotate in opposite directions. The rotating plate 23 drives the lever 231 to rotate synchronously. The grinding roller 26 and the rotating plate 23 descend synchronously. The inner ring of the bearing of the grinding roller 26 contacts the lever 231 and the upper surface of the inner ring of the bearing. When the grinding roller 26 grinds the inner ring of the bearing, the lever 231 rotates and contacts the transverse end 531 and drives the transverse end 531 to rotate synchronously. The transverse end 531 drives the clamping plate 53 and the second turntable 5 to rotate synchronously. The clamping plate 53 drives the bearing body 6 to rotate synchronously, and the rotation direction is opposite to that of the grinding roller 26. The grinding roller 26 can then grind the inner wall of the bearing body 6 in all directions.

[0037] After grinding, the first turntable 4 is driven to rotate the bearing body 6 to the discharge port 14, and the bearing body 6 is discharged through the discharge port 14.

[0038] This device fixes the bearing body 6 with clamp 53 and drives the bearing body 6 to rotate in the opposite direction, so that the grinding roller 26 has more sufficient contact with the inner wall of the bearing, avoiding local over-grinding or under-grinding caused by unidirectional rotation, thus improving the grinding effect.

[0039] like Figure 2 As shown, a servo motor 16 is fixedly connected to the lower surface of the base plate 1. The output end of the servo motor 16 is fixedly connected to the rotating end of the first turntable 4. A discharge rack 15 is fixedly connected to the lower surface of the base plate 1 and to one side of the discharge port 14. The discharge rack 15 is inclined.

[0040] Specifically, when it is necessary to drive the first turntable 4 to rotate intermittently, the servo motor 16 is turned on. The servo motor 16 drives the rotating end of the first turntable 4 to rotate 90 degrees, which can complete a series of automatic feeding, grinding and unloading operations. After grinding, the bearing body 6 moves to the discharge port 14 and falls into the discharge rack 15 through the discharge port 14, and is discharged through the discharge rack 15.

[0041] like Figure 4 As shown, a second support frame 13 is provided on one side of the first support frame 11. The second support frame 13 is fixedly connected to the upper surface of the base plate 1. An electric cylinder is fixedly connected to the lower surface of the second support frame 13. The telescopic end of the electric cylinder is fixedly connected to the inner bottom of the outer shell 22.

[0042] Specifically, when it is necessary to drive the grinding roller 26 and the lever 231 to descend, the electric cylinder can be activated. The telescopic rod of the electric cylinder passes through the rotating ends of the first bevel gear 232 and the third bevel gear 25 and is fixed to the inner lower surface of the housing 22. Therefore, the output end of the electric cylinder drives the housing 22 to descend, and the housing 22 drives the lever 231 and the grinding roller 26 to descend.

[0043] like Figure 5 As shown, a grinding motor 24 is fixedly connected to the outer wall of the housing 22, and a second bevel gear 241 is fixedly connected to the output end of the grinding motor 24. A first bevel gear 232 is fixedly connected to the rotating end of the rotating plate 23. The first bevel gear 232 and the second bevel gear 241 mesh with each other. A third bevel gear 25 is rotatably connected to the inner wall of the housing 22. A pulley 251 is fixedly connected to both the rotating end of the third bevel gear 25 and the rotating end of the grinding roller 26. The two pulleys 251 are connected by a belt drive. The third bevel gear 25 and the second bevel gear 241 mesh with each other.

[0044] Specifically, when it is necessary to drive the grinding roller 26 and the rotating plate 23 to rotate in opposite directions, the grinding motor 24 can be turned on. The grinding motor 24 drives the second bevel gear 241 to rotate. The second bevel gear 241 meshes with the first bevel gear 232 and the third bevel gear 25 respectively, so that the first bevel gear 232 drives the rotating plate 23 to rotate, the rotating plate 23 drives the lever 231 to rotate, and at the same time, the third bevel gear 25 drives the pulley 251 on its rotating end to rotate synchronously. The pulley 251 drives the pulley 251 on the rotating end of the grinding roller 26 to rotate synchronously through the belt, so that the grinding roller 26 rotates. At this time, the lever 231 and the grinding roller 26 can be driven to rotate in opposite directions.

[0045] like Figures 6 to 10As shown, a magnetic block 51 is slidably connected inside the second turntable 5. A pressing block 512 is fixedly connected to one side of the magnetic block 51. A moving rod 52 is slidably connected to one side of the pressing block 512. One end of the moving rod 52 is fixedly connected to one side of the clamping plate 53. A second elastic telescopic rod 511 is fixedly connected to the lower inner surface of the second turntable 5. The telescopic end of the second elastic telescopic rod 511 is slidably connected to the inside of the magnetic block 51. A fixing plate 3 is fixedly connected to one side of the second support frame 13. An electromagnet 31 is fixedly connected to the inner wall of the fixing plate 3. When energized, the magnetism of the electromagnet 31 and the magnetism of the magnetic block 51 repel each other. A roller 533 is rotatably connected to the side wall of the clamping plate 53. A limit frame 54 is fixedly connected to the inner wall of the second turntable 5. The inner wall of the limit frame 54 is slidably connected to the surface of the roller 533.

[0046] Specifically, when it is necessary to drive the clamping plate 53 to move, the second turntable 5 drives the magnetic block 51 to move below the electromagnetic plate, the electromagnet 31 is energized, so that the electromagnet 31 generates a repulsive force on the magnetic block 51, the magnetic block 51 slides inward to the second turntable 5, the magnetic block 51 squeezes the second elastic telescopic rod 511 and drives the squeezing block 512 to descend, the squeezing block 512 drives the moving rod 52 to move towards the outer wall of the bearing, the moving rod 52 drives the clamping plate 53 to slide synchronously, the clamping plate 53 drives the roller 533 to slide inside the limit frame 54, the clamping plate 53 contacts and clamps the outer wall of the bearing body 6, and at the same time the clamping plate 53 drives the transverse end 531 to contact the upper surface of the bearing body 6, so that the bearing body 6 can be fixed.

[0047] Example 2: Figures 6 to 10 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a plurality of protrusions 32 are fixedly connected to the inner lower surface of the fixed plate 3; a pressing rod 532 is fixedly connected to the upper surface of the clamping plate 53; a moving plate 17 is slidably connected inside the base plate 1; a filter tube 171 is fixedly connected inside the moving plate 17; a filter screen is provided at one end of the filter tube 171; a discharge valve is provided at one end of the filter tube 171; a first elastic telescopic rod 172 is fixedly connected to the lower surface of the base plate 1; and the telescopic end of the first elastic telescopic rod 172 is fixedly connected to the lower surface of the moving plate 17.

[0048] Specifically, when grinding the inner ring of a bearing, a small amount of tiny debris will remain on the stainless steel bearing inner ring during grinding. When the grinding roller 26 comes into contact with the debris again, it will cause grinding scratches.

[0049] To solve the above problems, this device operates as follows: When the lever 231 drives the clamping plate 53 to rotate, the clamping plate 53 drives the pressing rod 532 to rotate. When the pressing rod 532 rotates to the protrusion 32, the protrusion 32 presses against the pressing rod 532. The pressing rod 532 drives the clamping plate 53 to descend. The clamping plate 53 drives the bearing body 6 to descend through the transverse end 531. The bearing body 6 drives the moving plate 17 to descend. The moving plate 17 presses against the elastic second elastic telescopic rod 511. When the pressing rod 532 moves away from the protrusion 32, the second elastic telescopic rod 511 drives the moving plate 17 to reset. By repeating the above operation, the bearing body 6 can be vibrated back and forth. The debris on the inner wall of the bearing body 6 is shaken off to the filter screen and falls into the filter tube 171. At the same time, an external negative pressure device can be connected to one end of the discharge valve. The negative pressure device generates negative pressure, which can increase the cleaning of debris on the inner wall of the bearing.

[0050] This device can shake off the grinding debris adhering to the inner wall of the pipe, preventing the debris from contacting the grinding roller 26 and causing scratches on the inner wall. It can also prevent the debris from spreading and reduce secondary pollution.

[0051] Working principle: When using this device, the bearing body 6 in the unloading rack 12 falls into the second turntable 5 inside the first turntable 4. The servo motor 16 is turned on, and the servo motor 16 drives the rotating end of the first turntable 4 to rotate 90 degrees. The first turntable 4 drives the bearing body 6 inside the second turntable 5 to rotate synchronously. When the bearing body 6 rotates to the grinding mechanism 2, the electromagnet 31 is energized, so that the electromagnet 31 generates a repulsive force on the magnetic block 51. The magnetic block 51 slides inward to the second turntable 5, and the magnetic block 51 presses the second elastic telescopic rod 51. 1. The pressing block 512 descends, and the pressing block 512 drives the moving rod 52 to move towards the outer wall of the bearing. The moving rod 52 drives the clamping plate 53 to slide synchronously. The clamping plate 53 drives the roller 533 to slide inside the limiting frame 54. The clamping plate 53 contacts and clamps the outer wall of the bearing body 6. At the same time, the clamping plate 53 drives the transverse end 531 to contact the upper surface of the bearing body 6. The grinding motor 24 is turned on, and the grinding motor 24 drives the second bevel gear 241 to rotate. The second bevel gear 241 interacts with the first bevel gear 232 and the third bevel gear 241 respectively. When the bevel gears 25 mesh, the first bevel gear 232 drives the rotating plate 23 to rotate, which in turn drives the lever 231 to rotate. Simultaneously, the third bevel gear 25 drives the pulley 251 on its rotating end to rotate synchronously. The pulley 251 drives the pulley 251 on the rotating end of the grinding roller 26 to rotate synchronously via a belt, causing the grinding roller 26 to rotate. At this time, the lever 231 and the grinding roller 26 can be driven to rotate in opposite directions. The rotating plate 23 drives the lever 231 to rotate synchronously, and the output end of the electric cylinder drives the outer casing 22 to descend. The outer casing 22 drives the lever 231 to rotate in opposite directions. As rod 231 and grinding roller 26 descend, the inner ring of the bearing of grinding roller 26 contacts, and lever 231 contacts the upper surface of the inner ring of the bearing. When grinding roller 26 grinds the inner ring of the bearing, lever 231 rotates and contacts the transverse end 531, causing the transverse end 531 to rotate synchronously. The transverse end 531 causes clamping plate 53 and second turntable 5 to rotate synchronously. Clamping plate 53 causes bearing body 6 to rotate synchronously, and the rotation direction is opposite to that of grinding roller 26. Grinding roller 26 can then grind the inner wall of bearing body 6 in all directions.

[0052] When the lever 231 drives the clamping plate 53 to rotate, the clamping plate 53 drives the pressing rod 532 to rotate. The pressing rod 532 rotates to the protrusion 32, and the protrusion 32 presses the pressing rod 532. The pressing rod 532 drives the clamping plate 53 to descend. The clamping plate 53 drives the bearing body 6 to descend through the transverse end 531. The bearing body 6 drives the moving plate 17 to descend. The moving plate 17 presses the elastic second elastic telescopic rod 511. When the pressing rod 532 moves away from the protrusion 32, the second elastic telescopic rod 511 drives the moving plate 17 to reset. By repeating the above operation, the bearing body 6 can be vibrated back and forth. The debris on the inner wall of the bearing body 6 is shaken off to the filter screen and falls into the filter tube 171. At the same time, an external negative pressure device can be connected to one end of the discharge valve. The negative pressure device generates negative pressure, which can improve the cleaning effect of debris on the inner wall of the bearing.

[0053] After grinding, the first turntable 4 is driven to rotate the bearing body 6 to the discharge port 14, and the bearing body 6 is discharged through the discharge port 14.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
