Description

Technical Field

[0001] The present invention relates to the technical field of bearing processing, and specifically relates to a polishing device for bearing rings in the processing of deep groove ball bearings. Background Technique

[0002] The deep groove ball bearing is a kind of rolling bearing with relatively wide application. Its characteristics are small frictional resistance and high rotational speed. It can be used for parts that can bear radial loads or combined loads of radial and axial actions simultaneously, and can also be used for parts that bear axial loads, such as small power motors, automotive and tractor gearboxes, machine tool gearboxes, general machinery, tools, etc. The deep groove ball bearing generally consists of a bearing ring, rolling elements and a cage. The bearing ring includes an inner ring and an outer ring. Generally, the inner ring of the bearing is an annular shape with grooves on the outer wall. In order to remove the burrs on the surface of the bearing ring, make the surface of the bearing ring smoother and flatter, and improve the surface quality of the bearing ring, the bearing ring is generally polished during processing.

[0003] In the prior art, when polishing the inner ring of the bearing, the two sides and the inner wall of the inner ring of the bearing are polished through different processes respectively, resulting in low polishing efficiency of the bearing ring, time-consuming and laborious, and thus the processing cost is relatively high.

[0022] 1. For the deep groove ball bearing processing bearing ring polishing device, a workbench housing is provided, and a plurality of placing holes are arranged on the workbench housing, which can process multiple groups of workpieces at the same time. The workbench housing can rotate. When loading, the workbench housing is rotated to the horizontal position for easy loading. When polishing, the workbench housing is rotated to the upright position for easy polishing. Clamping mechanisms are symmetrically arranged on both sides of the placing holes to clamp and fix the workpieces and maintain the stability of the workpieces during the polishing process. By arranging grinding mechanisms on both sides of the workbench housing, the two side surfaces and the inner wall of the bearing inner ring can be ground and polished synchronously, improving the polishing efficiency of the bearing inner ring.

[0023] 2. The polishing device for the bearing ring of a deep groove ball bearing cools the grinding head and the inner ring of the bearing by spraying a spraying liquid through a spraying mechanism, avoiding deformation of the inner ring of the bearing due to excessive temperature, and cleaning the debris generated by grinding to prevent scratching of the inner ring of the bearing. Before the workpiece is installed in the placement hole, the clamping pressure of the clamping mechanism is small, facilitating the worker to press the workpiece into the placement hole and reducing the labor intensity of the work. During the operation of the spraying mechanism, that is, during the grinding and polishing of the workpiece, the clamping pressure of the clamping mechanism on the workpiece can be increased, thereby improving the clamping stability of the clamping mechanism on the workpiece and preventing the inner ring of the bearing from shaking during grinding and polishing, which affects the grinding and polishing quality.

[0024] 3. After the polishing of the deep groove ball bearing processing bearing ring is completed, during the process of the grinding mechanism moving away from the workpiece and resetting, it can drive the clamping head of the clamping mechanism away from the placement hole and the workpiece, enabling the clamping head to automatically disengage from the workpiece, facilitating the unloading of the workpiece.

Specific implementation mode

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0038] Embodiment 1, please refer to Figures 1 to 11 , a polishing device for machining bearing rings of deep groove ball bearings.

[0039] A polishing mechanism is provided at the upper end of the base 1. The polishing mechanism includes a driving component and two groups of polishing components respectively arranged on both sides of the workbench housing 4;

[0040] The driving component includes a first gear 23 and two groups of first racks 24 meshed and connected with the first gear 23;

[0041] The polishing assembly includes several groups of grinding heads 7, which correspond one-to-one to the placement holes 6. The grinding head 7 includes a first grinding part 701 and two groups of second grinding parts 702 symmetrically arranged on the side walls of the first grinding part 701. The first grinding parts 701 of the two groups of polishing assemblies are arranged perpendicular to each other.

[0042] Two groups of first brackets 2 are fixedly provided at the upper end of the base 1, and first rotating shafts 3 are rotatably provided on the two groups of first brackets 2 through bearings. The workbench shell 4 is fixedly provided between the two groups of first rotating shafts 3, and 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] Among them, the clamping mechanism includes a fixed block 8 and a clamping head 9. The fixed block 8 is fixedly arranged inside the workbench shell 4. A first spring 10 is connected to the fixed block 8. A connecting plate 11 is provided at the end of the first spring 10 away from the fixed block 8. A guide rod 12 is fixedly arranged 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 the limiting block 13. A second spring 14 is connected between the clamping head 9 and the connecting plate 11 and located on the outside of the guide rod 12. A first wedge block 30 is fixed at the end of the connecting plate 11. The two groups of first wedge blocks 30 are symmetrically arranged on the two symmetrically arranged clamping mechanisms.

[0044] Among them, the polishing assembly also includes a mounting plate 15, which is slidably arranged on the upper end of the base 1. A number of second rotating shafts 16 are rotatably arranged on the mounting plate 15 through bearings. The second rotating shafts 16 correspond one-to-one to the grinding heads 7. The corresponding second rotating shafts 16 are fixedly connected to the grinding heads 7. The two adjacent groups of second rotating shafts 16 are connected through belt transmission members 17. A first ∏-type mounting frame 18 is installed on the mounting plate 15, and a second motor 19 is installed on the first ∏-type mounting frame 18. The output shaft of the second motor 19 is fixedly connected to the second rotating shaft 16.

[0045] Among them, the driving assembly includes a second ∏-type mounting frame 20, a third motor 21 is fixedly installed on the upper end of the second ∏-type mounting frame 20, the output shaft of the third motor 21 is fixedly provided with a third rotating shaft 22, the first gear 23 is fixedly installed on the outer surface of the third rotating shaft 22, and two groups of first racks 24 are respectively meshed and connected to both sides of the first gear 23, and the two groups of first racks 24 are respectively fixedly connected to the mounting plates 15 of the two groups of polishing assemblies.

[0046] More specifically, in this embodiment: The size of the placement hole 6 is adapted to the inner ring of the bearing. 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, first, the inner ring of the bearing is 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 just moves to the clamping head 9, the clamping head 9 and the second spring 14 lose pressure, and the second spring 14 rebounds, driving the clamping head 9 to move and reset in the direction of the placement hole 6, so that the clamping head 9 is clamped into the groove opened on the outer wall of the inner ring of the bearing, and then the inner ring of the bearing is fixedly clamped in the placement hole 6;

[0047] Secondly, the first motor 5 works to drive the first rotating shaft 3 and the workbench housing 4 to rotate, turning the workbench housing 4 by 90 degrees so that the workbench housing 4 stands up. Then the third motor 21 works to drive the third rotating shaft 22 and the first gear 23 to rotate. Since the first gear 23 is meshed and connected with the first rack 24, the two first racks 24 are driven to move towards each other, so that the two first racks 24 move towards the middle direction, thereby driving the two mounting plates 15 to approach each other, and then driving the grinding heads 7 on both sides to approach each other until the second grinding part 702 of the grinding head 7 extends into the inner wall of the inner ring of the bearing, so that the first grinding parts 701 of the grinding heads 7 on both sides are respectively in contact with the two side surfaces of the inner ring of the bearing, and the second grinding part 702 of the grinding head 7 is in contact with the inner wall of the inner ring of the bearing. 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 part of the inner ring of the bearing, the second grinding parts 702 of the two polishing mechanisms are dispersedly arranged and will not contact each other, and the second grinding part 702 of one polishing mechanism will not contact the first grinding part 701 of the other polishing mechanism either;

[0048] Then the second motor 19 works to drive one of the second rotating shafts 16 to rotate. Through the belt transmission member 17, the other second rotating shafts 16 are driven to rotate. Among them, the belt transmission member 17 includes belt wheels respectively fixed on the two second rotating shafts 16 and a belt sleeved between the two belt wheels, so as to drive the grinding head 7 to rotate. During the rotation of the grinding head 7, the two side surfaces and the inner wall of the inner ring of the bearing are polished synchronously, improving the polishing efficiency of the inner ring of the bearing. It should be noted that in specific implementation, the rotation directions and rotation speeds 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 always remain the same, and the grinding heads 7 of the two polishing mechanisms will not hinder each other, so there will be no dead corners in grinding and polishing.

[0049] In this embodiment, first, the workbench housing 4 is placed horizontally. The worker installs the inner ring of the bearing into the placement hole 6 and fixes the inner ring of the bearing through the clamping mechanism. Then, the workbench housing 4 is rotated to a vertical position, and then the driving assembly is used to drive the two polishing assemblies to approach each other, that is, both polishing assemblies move towards the direction of the workbench housing 4 until the first polishing parts 701 of the polishing heads 7 of the two polishing assemblies respectively contact the two side surfaces of the inner ring of the bearing. At this time, the second polishing parts 702 have both extended into the inner ring of the bearing and contacted the inner wall of the inner ring of the bearing. After that, the second motor 19 of the polishing assembly is used to drive the polishing head 7 to rotate, and the two side surfaces and the inner wall of the inner ring of the bearing are polished synchronously.

[0050] Embodiment 2 is an improvement made on the basis of Embodiment 1. The purpose of this embodiment is to facilitate the solution of the problems that the high temperature generated by the friction between the polishing head 7 and the bearing ring during the polishing process will affect the structure of the bearing ring and the debris generated by polishing will scratch the surface of the bearing ring. Specifically, please refer to Figures 1 to 8 , two groups of second brackets 25 are provided at the upper end of the base 1. A top plate 26 is fixedly provided at the upper ends of the two groups of second brackets 25. A storage tank 27 is fixedly provided at the upper end of the top plate 26. A number of spray mechanisms are provided at the lower end of the top plate 26. The spray mechanisms correspond to the placement holes 6 one by one. The spray mechanisms are communicated with the storage tank 27 through a connecting main pipe 28. A water pump 29 is installed on the connecting main pipe 28.

[0051] More specifically, in this embodiment: during the polishing process, through the operation of the water pump 29, the spray liquid stored in the storage tank 27 is pumped to the spray mechanism, and the spray mechanism sprays the spray liquid onto the polishing head 7 and the inner ring of the bearing, so as to cool the polishing head 7 and the inner ring of the bearing, avoid deformation of the inner ring of the bearing due to excessive temperature, and clean the debris generated by polishing to avoid scratching the inner ring of the bearing.

[0052] Embodiment 3 is an explanatory description made on the basis of Embodiment 2. The purpose of this embodiment is to facilitate the solution of the problem that in order to load the material in a certain direction, the clamping pressure of the clamping mechanism is small before the inner ring of the bearing is pressed into the placement hole 6, and when polishing, the clamping mechanism maintains a unified elastic force, which will cause unstable clamping. Specifically, please refer to Figures 1 to 7 , the spray mechanism includes two groups of transfer cylinders 31. The side wall of the transfer cylinder 31 is provided with a first spray head 32. One end of a third spring 33 is connected to the upper end of the transfer cylinder 31, and the other end of the third spring 33 is connected to the lower end surface of the top plate 26. The upper end of the transfer cylinder 31 is fixedly communicated with a first connecting branch pipe 34, and the first connecting branch pipe 34 is fixedly communicated with the connecting main pipe 28;

[0053] When the spray liquid in the storage box 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, the first wedge block 30 is squeezed, and the connecting plate 11 is squeezed towards the center direction of the placing hole 6.

[0054] More specifically, in this embodiment: by the operation of the water pump 29, the spray liquid stored in the storage box 27 is pumped through the connecting main pipe 28 and the first connecting branch pipe 34 to the transfer cylinder 31, and the spray liquid is sprayed onto the grinding head 7 and the inner ring of the bearing through the first spray head 32. The gravity of the transfer cylinder 31 increases due to the injection of the spray liquid, so that the transfer cylinder 31 undergoes a downward displacement. 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 to the first wedge block 30 one by one, during the downward movement of the transfer cylinder 31, the first wedge block 30 is squeezed. Since the two groups of first wedge blocks 30 on the two groups of clamping mechanisms are symmetrically arranged, the connecting plate 11 is squeezed towards the center direction of the placing hole 6. At this time, the second spring 14 is compressed more tightly, so that the pressure of the second spring 14 on the clamping head 9 becomes larger, and further the clamping head 9 clamps the inner ring of the bearing more tightly, preventing the inner ring of the bearing from shaking during the grinding and polishing process and affecting 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 relatively loosely, and the pressure of the second spring 14 on the clamping head 9 is small, which is convenient for pressing the inner ring of the bearing into the placing hole 6 and reducing the labor intensity of workers. After the grinding and polishing are completed, the injection of the spray liquid into the transfer cylinder 31 is stopped, and the third spring 33 loses its tension and resets, so that the transfer cylinder 31 moves upward and resets, eliminating the extrusion force on the first wedge block 30 and the connecting plate 11.

[0055] Embodiment 4 is an improvement made on the basis of Embodiment 2. In order to load materials in one direction, before the inner ring of the bearing is pressed into the placing hole 6, the clamping pressure of the clamping mechanism is small, and when grinding and polishing, the clamping mechanism maintains a uniform elastic force, which will cause the problem of unstable clamping. Specifically, please refer to Figures 1 to 6 and Figure 8 , the spraying mechanism includes two piston cylinders 35. A piston plate 36 is slidably arranged in the piston cylinder 35. A piston rod 37 is fixedly arranged in the middle of the lower end of the piston plate 36. The piston rod 37 penetrates through the lower wall of the piston cylinder 35 and extends out of the piston cylinder 35. One end of a fourth spring 38 is connected to the lower end of the piston plate 36, and the other end of the fourth spring 38 is connected to the inner bottom wall of the piston cylinder 35. A second spray head 39 is installed on the side wall of the piston cylinder 35. The upper end of the piston cylinder 35 is fixedly communicated with a second connecting branch pipe 60, and the second connecting branch pipe 60 is fixedly communicated with the connecting main pipe 28;

[0056] When the spray liquid in the storage box 27 is injected into the piston cylinder 35, the spray liquid pushes the piston plate 36 and the piston rod 37 downward. In the process of the piston rod 37 moving downward, the first wedge block 30 is squeezed, and the connecting plate 11 is squeezed toward the center of the placement hole 6.

[0057] More specifically, in this embodiment: the water pump 29 works to pump the spray liquid stored in the storage box 27 to the piston cylinder 35 through the connecting main pipe 28 and the second connecting branch pipe 60. The spray liquid forms pressure on the piston plate 36, squeezing the piston plate 36 and the piston rod 37 downward. 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, and the spray liquid is sprayed from the second spray head 39 to the grinding head 7 and the inner ring of the bearing. The position of the piston cylinder 35 corresponds one-to-one to the first wedge block 30, so that the position of the piston rod 37 corresponds one-to-one to the first wedge block 30, so that in the process of the piston rod 37 moving downward, the first wedge block 30 is squeezed. Since the two groups of first wedge blocks 30 are symmetrically arranged on the two groups of clamping mechanisms, The connecting plate 11 is squeezed toward the center of the placement hole 6. At this time, the second spring 14 is compressed more tightly, so that the pressure of the second spring 14 on the clamping head 9 becomes greater, and the clamping head 9 clamps the inner ring of the bearing more tightly, preventing the inner ring of the bearing from shaking during the grinding and polishing process and affecting 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 small, which is convenient for pressing the inner ring of the bearing into the placement hole 6, reducing the labor intensity of the workers. After the grinding and polishing is completed, stop injecting the spray liquid into the piston cylinder 35, and the fourth spring 38 loses pressure and rebounds, moving the piston plate 36 and the piston rod 37 upward to reset, eliminating the squeezing force on the first wedge block 30 and the connecting plate 11.

This example is intended to solve the problem that the bearing ring located in the placement hole after processing is difficult to cut. For details, please refer to Figures 1 to 11 A second wedge block 40 is fixed to one end of the connecting plate 11 away from the first wedge block 30, and the two sets of second wedge blocks 40 on the two sets of symmetrically arranged clamping mechanisms are symmetrically arranged;

A fourth wedge block 61 is fixedly provided on the end of the support plate 42 away from the connecting rod 43.

[0060] An installation housing 45 is fixedly provided on the inner side wall of the first support 2. A slideway 46 is fixedly provided on the inner bottom wall of the installation housing 45. A slider 47 is slidably connected in the slideway 46. A follower block 48 is fixedly provided at the upper end of the slider 47. A sliding hole 49 is formed in the follower block 48. A sliding sleeve 50 is slidably connected in the sliding hole 49. A guiding column 51 is fixedly provided at the upper end of the sliding sleeve 50. An oblong hole 52 communicating with the sliding hole 49 is formed on the upper end surface of the follower block 48. The guiding column 51 passes through the oblong hole 52 and extends out of the upper end of the follower block 48. Limiting members 53 are fixedly provided at both ends of the inner bottom wall of the installation housing 45. The limiting member 53 includes a limiting frame 5301. A guiding opening groove 5302 is formed in the limiting frame 5301. The guiding opening groove 5302 includes a horizontal portion 53021 and an inclined portion 53022. The inclined portion 53022 communicates with the horizontal portion 53021. A fourth rotating shaft 54 is rotatably provided in the inner ring of the sliding sleeve 50 through a bearing. A second gear 55 is fixedly provided at one end of the fourth rotating shaft 54. Two groups of parallel guiding channels 56 are fixedly provided on the inner bottom wall of the installation housing 45. Second racks 57 are fixedly provided at the upper ends of the two groups of guiding channels 56, and the two groups of second racks 57 are respectively located at both ends of the two groups of guiding channels 56. The other end of the fourth rotating shaft 54 extends out of the installation housing 45 and is fixedly provided with a third wedge-shaped block 58. One end of the slider 47 is fixedly connected with a transmission rod 59. The end of the transmission rod 59 far away from the slider 47 is fixedly connected with a group of mounting plates 15.

[0061] More specifically, in this embodiment: the openings of the guiding opening grooves 5302 of the two sets of limiting members 53 face each other, and the directions of the inclined portions 53022 of the two guiding opening grooves 5302 are opposite. An avoidance groove is provided on the side wall of the mounting housing 45, and the fourth rotating shaft 54 passes through the avoidance groove and extends outside the mounting housing 45. The setting of the avoidance groove does not hinder the movement of the fourth rotating shaft 54. In the initial state, the guiding column 51 is located in the guiding opening groove 5302 of one set of limiting members 53, the flat surface of the third wedge block 58 faces upward and the inclined surface faces downward. During the process of the third motor 21 working to drive the mounting plate 15 to move towards the workbench housing 4, through the transmission rod 59, the slider 47 is driven to slide in the slideway 46, thereby driving the follower block 48 to move following the slider 47, so that the fourth rotating shaft 54, the third wedge block 58 and the second gear 55 move. At this time, the second gear 55 moves along one of the guiding paths 56. When the second gear 55 moves at the second rack 57 on this guiding path 56, the second gear 55 will rotate, thereby driving the fourth rotating shaft 54 and the third wedge block 58 to rotate, so that the third wedge block 58 performs the first flip, flipping 180 degrees, turning the inclined surface of the third wedge block 58 upward, and making the height of the third wedge block 58 after the first flip higher than the height of the third wedge block 58 before the first flip. Then the slider 47 continues to drive the follower block 48 to move. At this time, the guiding column 51 is moved to the guiding opening groove 5302 of the other set of limiting members 53, and the guiding column 51 is guided to the horizontal portion 53021 through the inclined portion 53022 of the guiding opening groove 5302, so that the guiding column 51, the sliding sleeve 50, the fourth rotating shaft 54, the second gear 55 and the third wedge block 58 undergo a lateral displacement, and the second gear 55 is moved to the upper end of the other guiding path 56. When the grinding and polishing are completed, during the process of the third motor 21 driving the mounting plate 15 to move in the reverse direction and reset, through the transmission rod 59, the slider 47 is driven to slide in the slideway 46 in the reverse direction, thereby driving the third wedge block 58 to move. At this time, the third wedge block 58 and the fourth wedge block 61 are on the same vertical plane. When the third wedge block 58 moves below the fourth wedge block 61, it will exert a squeeze on the fourth wedge block 61, causing the fourth wedge block 61, the support plate 42, the connecting rod 43 and the pushing block 44 to move upward. During the process of the pushing block 44 moving upward, it will squeeze the second wedge blocks 40 on both sides of it outward, driving the connecting plate 11 to move away from the placing hole 6, thereby driving the clamping head 9, the guiding rod 12, the limiting block 13 and the second spring 14 to move away from the placing hole 6, so that the clamping head 9 disengages from the inner ring of the bearing, thus facilitating the unloading of the inner ring of the bearing. When the unloading of the inner ring of the bearing is completed, the mounting plate 15 continues to drive the slider 47 to move. When the second gear 55 moves at the second rack 57 at the upper end of the other guiding path 56, the second gear 55 rotates again, thereby driving the fourth rotating shaft 54 and the third wedge block 58 to rotate again, so that the third wedge block 58 performs the second flip.Reverse and flip it by 180 degrees, flip the third wedge block 58 back to the state with the plane facing up and the inclined plane facing down. Finally, through the guiding opening groove 5302 of a set of limiting members 53 guiding the guiding column 51, the fourth rotating shaft 54, the third wedge block 58, and the second gear 55 are moved again, and the fourth rotating shaft 54, the third wedge block 58, and the second gear 55 are moved back to the initial state.
