Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-3 This utility model provides a technical solution: a grinding device for the inner and outer surfaces of a ring forging, comprising a processing base 1 and a ring forging 30. A first rotating shaft 2 is rotatably mounted on the upper part of one side of the processing base 1, and a first grinding roller 3 is fixedly welded to the upper part of the first rotating shaft 2. A first sliding groove 4 is provided on the upper part of the processing base 1, and a second rotating shaft 5 is slidably mounted inside the first sliding groove 4. A second grinding roller 6 is fixedly welded to the upper part of the second rotating shaft 5. By moving the second rotating shaft 5 along the first sliding groove 4, the ring forging 30 is clamped between the first grinding roller 3 and the second grinding roller 6. Two sets of second sliding grooves 7 are provided on the upper part of the processing base 1, and a second grinding roller 6 is slidably mounted inside the second sliding groove 7. The third rotating shaft 8 has a fixed roller 9 welded to its upper part. By moving the third rotating shaft 8 along the second sliding groove 7, the fixed roller 9 is made to fit tightly against the inner wall of the ring forging 30, thereby supporting the inside of the ring forging 30. A second motor 16 is installed on the flange on one side of the upper part of the processing seat 1. The power end of the second motor 16 passes through the coupling of the processing seat 1 and is connected to the fourth rotating shaft 17. A first transmission belt 18 is sleeved on the outer side of the fourth rotating shaft 17 and the first rotating shaft 2. The second motor 16 drives the fourth rotating shaft 17, which drives the first rotating shaft 2 to rotate through the first transmission belt 18, thereby driving the first grinding roller 3 to rotate and grind the ring forging 30.
[0018] A movable plate 10 is rotatably mounted on the lower outer side of the second rotating shaft 5. Two sets of lugs 11 are fixedly welded to the front and rear sides of the movable plate 10. A first threaded rod 12 is threaded inside the front lug 11, and a sliding rod 13 is slidably mounted inside the rear lug 11. Two sets of mounting brackets 14 are fixedly welded to the lower part of the machining base 1. The two ends of the sliding rod 13 are fixedly welded to the rear mounting bracket 14. A first motor 15 is mounted on a flange on one side of the front mounting bracket 14. The power end of the first motor 15 is connected to the first threaded rod 12 via a coupling. The other end of the first threaded rod 12 is rotatably connected to the mounting bracket 14. The first motor 15 drives the first threaded rod 12. 2. The movable plate 10 is moved by the lug 11. The other side of the movable plate 10 moves along the sliding rod 13 via the lug 11, thereby ensuring the balance of both sides of the movable plate 10, which in turn drives the second rotating shaft 5 to move. A fifth rotating shaft 19 is rotatably mounted on the lower part of the processing seat 1. A rotating arm 21 is fixedly welded to the other end of the fifth rotating shaft 19. A torsion spring 20 is fixedly welded between the rotating arm 21 and the processing seat 1. The torsion spring 20 is sleeved on the outside of the fifth rotating shaft 19. A push rod 22 is rotatably connected to the other end of the rotating arm 21. A second transmission belt 23 is sleeved on the outside of the push rod 22, the first rotating shaft 2, and the second rotating shaft 5. 0 By pulling the rotating arm 21, the push rod 22 presses the second transmission belt 23, ensuring that the second transmission belt 23 remains taut when the second grinding roller 6 moves, so that the second grinding roller 6 grinds the inner side of the ring forging 30; a mounting box 24 is fixedly welded to the lower part of the processing seat 1, and a first bevel gear 25 is rotatably connected to the middle of the mounting box 24. A rotating cap 29 is fixedly welded to the tail of the first bevel gear 25 through the mounting box 24. Second bevel gears 26 are meshed on both sides of the first bevel gear 25. A second threaded rod 27 is fixedly welded to the tail of the second bevel gear 26. The tail of the second threaded rod 27 is rotatably connected to the mounting box 24. The outer side of the threaded rod 27 is threaded with a movable block 28. The upper part of the movable block 28 is rotatably connected to the third rotating shaft 8. The first bevel gear 25 is driven to rotate through the rotating cap 29. The first bevel gear 25 meshes with the second bevel gear 26 to drive the second threaded rod 27 to rotate, thereby driving the movable block 28 to move, ensuring that the fixed rollers 9 on both sides move the same distance. Several sets of limiting rings 31 are fixedly welded to the outer side of the first rotating shaft 2, the second rotating shaft 5 and the fourth rotating shaft 17. The limiting rings 31 are set on the upper and lower sides of the first transmission belt 18 and the second transmission belt 23 to prevent the first transmission belt 18 and the second transmission belt 23 from moving.
[0019] Working principle: In use, the first motor 15 drives the first threaded rod 12, which moves the moving plate 10 through the lug 11, thereby moving the second rotating shaft 5 to clamp the ring forging 30 between the first grinding roller 3 and the second grinding roller 6. The rotating cap 29 drives the first bevel gear 25 to rotate, and the first bevel gear 25 meshes with the second bevel gear 26 to drive the second threaded rod 27 to rotate, thereby moving the moving block 28. The moving block 28 drives the third rotating shaft 8 to move along the second sliding groove 7, thereby making the fixed roller 9 fit tightly against the ground. The inner wall of the ring forging 30 is supported by the second motor 16, which drives the fourth rotating shaft 17 to rotate the first rotating shaft 2 via the first transmission belt 18, thereby driving the first grinding roller 3 to rotate and grind the outer side of the ring forging 30. The torsion spring 20 pulls the rotating arm 21 to make the push rod 22 press the second transmission belt 23 to ensure that the second transmission belt 23 remains taut when the second grinding roller 6 moves. The second transmission belt 23 drives the second grinding roller 6 to rotate, so that the second grinding roller 6 grinds the inner side of the ring forging 30.
