Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, specifically to a polishing device for the bearing ring of a deep groove ball bearing. Background Technology

[0002] Deep groove ball bearings are a widely used type of rolling bearing. They are characterized by low frictional resistance and high speed. They can be used in components that bear radial loads or combined radial and axial loads, as well as components that bear axial loads, such as small power electric motors, automotive and tractor gearboxes, machine tool gearboxes, and general machines and tools. Deep groove ball bearings generally consist of bearing rings, rolling elements, and a cage. The bearing rings include an inner ring and an outer ring. Generally, the inner ring is a grooved annular ring. To remove burrs from the surface of the bearing rings and make the surface smoother and flatter, thus improving the surface quality, the bearing rings are usually polished during processing.

[0003] In the existing technology, when polishing the inner ring of a bearing, different processes are used to grind the two sides and the inner wall of the bearing inner ring separately. This results in low polishing efficiency, is time-consuming and labor-intensive, and thus has a high processing cost. Summary of the Invention

[0021] The present invention has the following beneficial effects:

[0022] 1. This deep groove ball bearing processing and polishing device includes a worktable housing with several placement holes, enabling simultaneous processing of multiple workpieces. The worktable housing is rotatable; during loading, it is rotated to a horizontal position for easy loading, and during polishing, it is rotated to an upright position for easy polishing. Symmetrical clamping mechanisms are arranged on both sides of the placement holes to clamp and fix the workpieces, maintaining stability during the polishing process. By setting grinding mechanisms on both sides of the worktable housing, the two sides and inner wall of the bearing inner ring can be polished simultaneously, improving the polishing efficiency of the bearing inner ring.

[0023] 2. This deep groove ball bearing machining bearing ring polishing device uses a spray mechanism to spray liquid onto the grinding head and the bearing inner ring, cooling them to prevent deformation due to overheating. It also cleans up grinding debris, preventing scratches on the bearing inner ring. Before the workpiece is installed in the placement hole, the clamping pressure of the clamping mechanism is low, making it easier for workers to press the workpiece into the hole and reducing labor intensity. During the spray mechanism's operation, i.e., during the workpiece grinding and polishing process, the clamping pressure of the clamping mechanism is increased, thereby improving the stability of the clamping mechanism and preventing the bearing inner ring from shaking during grinding and polishing, which would affect the grinding and polishing quality.

[0024] 3. The bearing ring polishing device for deep groove ball bearing processing, after polishing, during the resetting process of the grinding mechanism away from the workpiece, can drive the clamping head of the clamping mechanism away from the placement hole and the workpiece, so that the clamping head automatically disengages from the workpiece, which facilitates the unloading of the workpiece.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1, please refer to Figures 1 to 11 A deep groove ball bearing processing bearing ring polishing device, wherein a rotatable worktable housing 4 is provided on the upper end of the base 1, and a plurality of placement holes 6 are provided on the worktable housing 4, and clamping mechanisms are symmetrically provided inside the worktable housing 4 and on both sides of the placement holes 6.

[0039] The upper end of the base 1 is provided with a polishing mechanism, which includes a drive assembly and two sets of polishing components respectively located on both sides of the worktable housing 4.

[0040] The drive assembly includes a first gear 23 and two sets of first racks 24 meshing with the first gear 23;

[0041] The polishing assembly includes several sets of grinding heads 7, each grinding head 7 corresponding to a placement hole 6. Each grinding head 7 includes a first grinding part 701 and two sets of second grinding parts 702 symmetrically arranged on the sidewall of the first grinding part 701. The first grinding parts 701 of the two sets of polishing assemblies are arranged perpendicular to each other.

[0042] Two sets of first brackets 2 are fixedly provided on the upper end of the base 1. Each set of first brackets 2 is provided with a first rotating shaft 3 through bearings. The workbench housing 4 is fixed between the two sets of first rotating shafts 3. A first motor 5 is installed on the first bracket 2. The output shaft of the first motor 5 is fixedly connected to the first rotating shaft 3.

[0043] The clamping mechanism includes a fixing block 8 and a clamping head 9. The fixing block 8 is fixed inside the workbench housing 4. A first spring 10 is connected to the fixing block 8. A connecting plate 11 is provided at the end of the first spring 10 away from the fixing block 8. A guide rod 12 is fixed at the end of the clamping head 9 away from the placement hole 6. The end of the guide rod 12 away from the clamping head 9 passes through the connecting plate 11 and is fixedly connected to a limit block 13. A second spring 14 is connected between the clamping head 9 and the connecting plate 11 and outside the guide rod 12. A first wedge block 30 is fixed at the end of the connecting plate 11. Two sets of first wedge blocks 30 are symmetrically arranged on the two sets of clamping mechanisms.

[0044] The polishing assembly also includes a mounting plate 15, which is slidably mounted on the upper end of the base 1. Several second rotating shafts 16 are rotatably mounted on the mounting plate 15 via bearings. Each second rotating shaft 16 corresponds to a grinding head 7, and the corresponding second rotating shafts 16 are fixedly connected to the grinding head 7. Adjacent sets of second rotating shafts 16 are connected by a belt drive 17. A first Π-shaped mounting bracket 18 is mounted on the mounting plate 15, and a second motor 19 is mounted on the first Π-shaped mounting bracket 18. The output shaft of the second motor 19 is fixedly connected to the second rotating shafts 16.

[0045] The drive assembly includes a second Π-shaped mounting bracket 20, a third motor 21 is fixedly mounted on the upper end of the second Π-shaped mounting bracket 20, a third rotating shaft 22 is fixedly mounted on the output shaft of the third motor 21, a first gear 23 is fixedly mounted on the outer surface of the third rotating shaft 22, two sets of first racks 24 are respectively meshed and connected to both sides of the first gear 23, and the two sets of first racks 24 are respectively fixedly connected to the mounting plates 15 of the two polishing assemblies.

[0046] More specifically, in this embodiment: the size of the placement hole 6 is adapted to the inner ring of the bearing, and the end face of the clamping head 9 is conical. In the initial state, the workbench housing 4 is placed horizontally, and the clamping head 9 extends into the placement hole 6. During processing, the inner ring of the bearing is first pressed into the placement hole 6. During the process of pressing the inner ring of the bearing into the placement hole 6, the outer wall of the inner ring of the bearing will squeeze the conical surface of the clamping head 9 extending into the placement hole 6, causing the clamping head 9 to move outward of the placement hole 6. At this time, the second spring 14 will be compressed until the groove opened on the outer wall of the inner ring of the bearing moves exactly to the clamping head 9. Then the clamping head 9 and the second spring 14 lose pressure, and the second spring 14 rebounds, driving the clamping head 9 to move back to the placement hole 6, thereby making the clamping head 9 fit into the groove opened on the outer wall of the inner ring of the bearing, and thus fixing the inner ring of the bearing in the placement hole 6.

[0047] Next, the first motor 5 operates, driving the first rotating shaft 3 and the worktable housing 4 to rotate, rotating the worktable housing 4 90 degrees so that the worktable housing 4 stands upright. Then, the third motor 21 operates, driving the third rotating shaft 22 and the first gear 23 to rotate. Since the first gear 23 is meshed with the first rack 24, it drives the two sets of first racks 24 to move towards each other, causing the two sets of first racks 24 to move towards the center, thereby driving the two sets of mounting plates 15 to move closer to each other, and in turn driving the grinding heads 7 on both sides to move closer to each other, until the second grinding part 702 of the grinding head 7. The grinding heads 7 extend into the inner wall of the bearing inner ring, so that the first grinding parts 701 of the two grinding heads 7 contact the two sides of the bearing inner ring respectively, and the second grinding parts 702 of the grinding heads 7 contact the inner wall of the bearing inner ring. Since the first grinding parts 701 of the two polishing mechanisms are arranged perpendicular to each other, after the second grinding parts 702 of the two polishing mechanisms are inserted into the inner ring of the bearing, the second grinding parts 702 of the two polishing mechanisms are dispersed and will not contact each other. The second grinding part 702 of one polishing mechanism will not contact the first grinding part 701 of the other polishing mechanism.

[0048] Then, the second motor 19 operates, driving one set of second rotating shafts 16 to rotate. Through the belt drive 17, the other second rotating shafts 16 rotate. The belt drive 17 includes pulleys fixed on the two sets of second rotating shafts 16 and a belt sleeved between the two pulleys, thereby driving the grinding head 7 to rotate. During the rotation of the grinding head 7, the two sides and inner wall of the bearing inner ring are polished simultaneously, improving the polishing efficiency of the bearing inner ring. It should be noted that in specific implementation, the rotation direction and speed of the grinding heads 7 of the two polishing mechanisms are kept consistent, so that the relative positions of the grinding heads 7 of the two polishing mechanisms are always consistent. The grinding heads 7 of the two polishing mechanisms will not obstruct each other, so there will be no dead corners in the polishing.

[0049] In this embodiment, the workbench housing 4 is first placed horizontally, and the operator inserts the bearing inner ring into the placement hole 6. The bearing inner ring is fixed by the clamping mechanism. Then, the workbench housing 4 is rotated to stand upright. The two polishing components are then driven to move closer to each other by the drive assembly, that is, both polishing components move towards the workbench housing 4 until the first polishing part 701 of the polishing head 7 of the two polishing components contacts the two sides of the bearing inner ring respectively. At this time, the second polishing part 702 has extended into the interior of the bearing inner ring and contacts the inner wall of the bearing inner ring. Then, the second motor 19 of the polishing assembly drives the polishing head 7 to rotate, and the two sides and inner wall of the bearing inner ring are polished simultaneously.

[0050] Example 2 is an improvement upon Example 1. This example aims to address the issues of high temperatures generated during the grinding and polishing process, where friction between the grinding head 7 and the bearing ring affects the bearing ring structure, and polishing debris scratches the bearing ring surface. For details, please refer to [link to example]. Figures 1 to 8 The base 1 has two sets of second brackets 25 on its upper end. The two sets of second brackets 25 are fixedly mounted on a top plate 26. The top plate 26 is fixedly mounted on a storage box 27. The bottom of the top plate 26 is equipped with several sets of spraying mechanisms. The spraying mechanisms correspond one-to-one with the placement holes 6. The spraying mechanisms and the storage box 27 are connected by a connecting pipe 28. A water pump 29 is installed on the connecting pipe 28.

[0051] More specifically, in this embodiment: during the grinding and polishing process, the water pump 29 operates to pump the spray liquid stored in the storage tank 27 to the spraying mechanism, which sprays the spray liquid onto the grinding head 7 and the inner ring of the bearing, thereby cooling the grinding head 7 and the inner ring of the bearing, preventing the inner ring of the bearing from deforming due to excessive temperature, and cleaning up the debris generated during grinding to prevent scratches on the inner ring of the bearing.

[0052] Example 3 is an explanation based on Example 2. This example aims to address the problem that, due to the relatively low clamping pressure of the clamping mechanism before the bearing inner ring is pressed into the placement hole 6 for directional feeding, and the instability caused by the clamping mechanism maintaining a uniform elasticity during grinding and polishing, the clamping mechanism may not be able to hold the bearing securely. For details, please refer to [link to relevant documentation]. Figures 1 to 7 The spraying mechanism includes two sets of central rotating cylinders 31. A first spray head 32 is installed on the side wall of the central rotating cylinder 31. The upper end of the central rotating cylinder 31 is connected to one end of a third spring 33. The other end of the third spring 33 is connected to the lower end face of the top plate 26. A first connecting branch pipe 34 is fixedly connected to the upper end of the central rotating cylinder 31. The first connecting branch pipe 34 is fixedly connected to the connecting main pipe 28.

[0053] When the spray liquid in the storage tank 27 is injected into the transfer cylinder 31, the gravity of the transfer cylinder 31 increases and it moves downward. During the downward movement of the transfer cylinder 31, it squeezes the first wedge block 30 and squeezes the connecting plate 11 toward the center of the placement hole 6.

[0054] More specifically, in this embodiment: the water pump 29 operates, pumping the spray liquid stored in the storage tank 27 through the connecting main pipe 28 and the first connecting branch pipe 34 into the transfer cylinder 31. The spray liquid is then sprayed onto the grinding head 7 and the inner ring of the bearing through the first spray head 32. The weight of the transfer cylinder 31 increases due to the injection of spray liquid, causing the transfer cylinder 31 to move downward. The third spring 33 is a tension spring, and at this time, the third spring 33 is stretched. Since the position of the transfer cylinder 31 corresponds one-to-one with the first wedge block 30, the first wedge block 30 is squeezed during the downward movement of the transfer cylinder 31. Because the two sets of first wedge blocks 30 on the two symmetrically arranged clamping mechanisms are symmetrically arranged, the connecting plate 11 is oriented towards the placement... When the center of hole 6 is pressed, the second spring 14 is compressed more tightly, which increases the pressure of the second spring 14 on the clamping head 9, and makes the clamping head 9 clamp the inner ring of the bearing more tightly. This prevents the inner ring of the bearing from shaking during the grinding and polishing process, which would affect the grinding and polishing quality. It should be noted that before the inner ring of the bearing is installed, the second spring 14 is compressed more loosely, and the pressure of the second spring 14 on the clamping head 9 is less, which makes it easier to press the inner ring of the bearing into the placement hole 6 and reduce the labor intensity of the workers. After the grinding and polishing is completed, the injection of spray liquid into the central rotating cylinder 31 is stopped, and the third spring 33 loses its tension and resets, thereby causing the central rotating cylinder 31 to move upward and reset, eliminating the squeezing force on the first wedge block 30 and the connecting plate 11.

[0055] Example 4 is an improvement on Example 2. To ensure proper orientation during feeding, the clamping pressure of the clamping mechanism is relatively low before the inner ring of the bearing is pressed into the placement hole 6. However, maintaining a uniform elastic force during grinding and polishing can cause clamping instability. For details, please refer to [link to relevant documentation]. Figures 1 to 6 and Figure 8 The spraying mechanism includes two sets of piston cylinders 35. A piston plate 36 is slidably disposed inside the piston cylinder 35. A piston rod 37 is fixedly disposed at the middle of the lower end of the piston plate 36. The piston rod 37 passes through the lower wall of the piston cylinder 35 and extends out of the piston cylinder 35. The lower end of the piston plate 36 is connected to one end of the fourth spring 38. The other end of the fourth spring 38 is connected to the bottom wall of the piston cylinder 35. A second spray head 39 is installed on the side wall of the piston cylinder 35. A second connecting branch pipe 60 is fixedly connected to the upper end of the piston cylinder 35. The second connecting branch pipe 60 is fixedly connected to the connecting main pipe 28.

[0056] When the spray liquid in the storage tank 27 is injected into the piston cylinder 35, the spray liquid pushes the piston plate 36 and piston rod 37 downward. During the downward movement of the piston rod 37, it squeezes the first wedge block 30, squeezing the connecting plate 11 toward the center of the placement hole 6.

[0057] More specifically, in this embodiment: the water pump 29 operates, pumping the spray liquid stored in the storage tank 27 through the connecting main pipe 28 and the second connecting branch pipe 60 to the piston cylinder 35. The spray liquid exerts pressure on the piston plate 36, squeezing the piston plate 36 and piston rod 37 downwards. At this time, the fourth spring 38 is compressed until the piston plate 36 moves to the lower end of the second spray head 39. The spray liquid is sprayed from the second spray head 39 onto the grinding head 7 and the inner ring of the bearing. The position of the piston cylinder 35 corresponds one-to-one with the first wedge block 30, so that the position of the piston rod 37 corresponds one-to-one with the first wedge block 30. Thus, during the downward movement of the piston rod 37, it squeezes the first wedge block 30. Since the two sets of first wedge blocks 30 on the symmetrically arranged clamping mechanisms are symmetrically arranged, thus... Press the connecting plate 11 toward the center of the placement hole 6. At this time, the second spring 14 is compressed more tightly, which increases the pressure of the second spring 14 on the clamping head 9, and makes the clamping head 9 clamp the bearing inner ring more tightly. This prevents the bearing inner ring from shaking during the grinding and polishing process, which would affect the grinding and polishing quality. It should be noted that before the bearing inner ring is installed, the second spring 14 is compressed more loosely, and the pressure of the second spring 14 on the clamping head 9 is smaller, which makes it easier to press the bearing inner ring into the placement hole 6 and reduce the labor intensity of the workers. After the grinding and polishing is completed, stop injecting spray liquid into the piston cylinder 35. The fourth spring 38 loses pressure and rebounds, moving the piston plate 36 and piston rod 37 upward to reset, eliminating the squeezing force on the first wedge block 30 and the connecting plate 11.

[0058] Example 5 is an improvement upon Example 2. This example aims to address the problem of inconvenient unloading of the bearing ring located within the placement hole after machining. For details, please refer to [link / reference]. Figures 1 to 11 A second wedge block 40 is fixedly provided at one end of the connecting plate 11 away from the first wedge block 30, and two sets of second wedge blocks 40 are symmetrically arranged on the two sets of clamping mechanisms.

A sliding sleeve 50 is slidably connected in the sliding hole 49. A guide post 51 is fixedly installed at the upper end of the sliding sleeve 50. An oblong hole 52 communicating with the sliding hole 49 is opened on the upper end face of the follower block 48. The guide post 51 passes through the oblong hole 52 and extends out of the upper end of the follower block 48. Limiting members 53 are fixedly installed at both ends of the bottom inner wall of the mounting housing 45. The limiting members 53 include a limiting frame 5301. A guide opening groove 5302 is opened on the limiting frame 5301. 2 includes a horizontal part 53021 and an inclined part 53022. The inclined part 53022 is connected to the horizontal part 53021. The inner ring of the sliding sleeve 50 is provided with a fourth rotating shaft 54 ​​through a bearing. A second gear 55 is fixedly provided at one end of the fourth rotating shaft 54. Two sets of parallel guide channels 56 are fixedly provided on the bottom wall of the mounting housing 45. A second rack 57 is fixedly provided at the upper end of each of the two sets of guide channels 56. The two sets of second racks 57 are located at the two ends of the two sets of guide channels 56 respectively. The other end of the fourth rotating shaft 54 ​​extends out of the mounting housing 45 and is fixedly provided with a third wedge block 58. A transmission rod 59 is fixedly connected to the end of the slider 47. The end of the transmission rod 59 away from the slider 47 is fixedly connected to a set of mounting plates 15.

[0061] More specifically, in this embodiment: the openings of the guide slots 5302 of the two sets of limiting members 53 are arranged facing each other, and the inclined portions 53022 of the two guide slots 5302 are in opposite directions. A clearance groove is provided on the side wall of the mounting housing 45. The fourth rotating shaft 54 ​​passes through the clearance groove and extends out of the mounting housing 45. The clearance groove does not obstruct the movement of the fourth rotating shaft 54. In the initial state, the guide post 51 is located in the guide slots 5302 of the set of limiting members 53. The plane of the third wedge block 58 faces upward and the inclined surface faces downward. During the process of the third motor 21 driving the mounting plate 15 to move towards the worktable housing 4, the transmission rod 59 transmits the signal, causing the slider 47 to slide in the slide rail 46, thereby causing the follower block 48 to move with the slider 47. This causes the fourth rotating shaft 54, the third wedge block 58, and the second gear 55 to move. During this movement, the second gear 55 moves along one of the guide channels 56. As the second gear 55 moves along the second rack 57 on this guide channel 56, it rotates, causing the fourth rotating shaft 54 ​​and the third wedge block 58 to rotate. This causes the third wedge block 58 to flip 180 degrees, turning its inclined surface upwards, making its height higher than before the first flip. Then, the slider 47 continues to move the follower block 48. At this time, the guide post 51 is moved to the guide opening slot 5302 of another set of limiting members 53, passing through the guide opening... The inclined portion 53022 of the groove 5302 guides the guide post 51 towards the horizontal portion 53021, thereby causing the guide post 51, the sliding sleeve 50, the fourth rotating shaft 54, the second gear 55, and the third wedge block 58 to undergo lateral displacement. The second gear 55 is moved to the upper end of another guide track 56. After grinding and polishing are completed, during the reverse movement and reset process of the third motor 21 driving the mounting plate 15, the transmission rod 59 is used to drive the slider 47 to slide in the reverse direction within the slide track 46, thereby driving the third wedge block 58 to move. At this time, the third wedge block 58 and the fourth wedge block 61 are located on the same vertical plane. When the third wedge block 58 moves to below the fourth wedge block 61, it will compress the fourth wedge block 61, causing the fourth wedge block 61, the support plate 42, and the connecting plate to... As the connecting rod 43 and push block 44 move upward, the push block 44 pushes the second wedge blocks 40 on both sides of it outward, causing the connecting plate 11 to move away from the placement hole 6. This, in turn, causes the clamping head 9, guide rod 12, limit block 13, and second spring 14 to move away from the placement hole 6, allowing the clamping head 9 to disengage from the bearing inner ring, thus facilitating the unloading of the bearing inner ring. After the bearing inner ring is unloaded, the mounting plate 15 continues to move the slider 47. As the second gear 55 moves at the second rack 57 at the upper end of another guide track 56, the second gear 55 rotates again, causing the fourth rotating shaft 54 ​​and the third wedge block 58 to rotate, resulting in a second flip of the third wedge block 58.The third wedge block 58 is flipped 180 degrees in the opposite direction, returning to a position where the flat side faces upward and the inclined side faces downward. Finally, guided by the guide slots 5302 of a set of limiting members 53, the guide post 51 is guided, causing the fourth rotating shaft 54, the third wedge block 58, and the second gear 55 to move again, returning them to their initial state.
