Description

Technical Field

[0001] This invention relates to the field of bearing ring processing technology, and more specifically to a bearing ring grinding device for bearing processing. Background Technology

[0002] Bearings are mechanical components that fix and reduce the coefficient of friction of loads during mechanical transmission. A bearing consists of an inner ring, an outer ring, and balls. In actual production, the inner ring, outer ring, and balls are manufactured separately and then assembled into a complete support. The inner and outer rings need to be polished during production.

[0003] Chinese patent application CN202411129146.6 discloses a bearing ring outer surface grinding device, including a grinding machine mounted on a frame. The frame has a rotary feed structure. The rotary feed structure includes a rotating frame rotatably connected within the frame, a drive device, a drive gear, a transmission gear, a gear ring, a clamping ring, a reciprocating screw, a reciprocating screw block, a support sleeve, and an inner support clamping structure mounted on the support sleeve. The clamping ring is mounted on the rotating frame, and the gear ring is connected to the rotating frame. The gear ring meshes with the transmission gear, which in turn meshes with the drive gear. The drive gear is mounted on the drive shaft of the drive device. The drive shaft of the drive device is connected to the reciprocating screw via a control structure, and the reciprocating screw block is connected to the reciprocating screw. This invention ensures the stability of the rotary feed during bearing ring grinding and allows for positioning control of the grinding machine, making the grinding work easier to complete.

[0004] Since bearing ring grinding is usually divided into rough grinding and fine grinding, rough grinding quickly removes excess material to ensure basic roundness, while fine grinding further refines the surface and improves dimensional accuracy and smoothness. However, existing grinding equipment cannot automatically switch between rough grinding plates and fine grinding plates, thus reducing the grinding effect of bearing rings.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0023] like Figures 1 to 10 As shown, the present invention provides a bearing ring grinding device for bearing processing, comprising: a machine base 1; a chuck 4 fixedly mounted on the machine base 1; a mounting bracket 2 fixedly mounted on the machine base 1; a grinding mechanism 5 for grinding the bearing ring; and a cooling mechanism 6 for cooling the bearing ring during grinding.

[0024] Before grinding, the bearing ring can be fixed by the chuck 4; the chuck 4 is preferably an electric three-jaw chuck 4.

[0025] The polishing mechanism 5 includes: a coarse polishing plate 51; a fine polishing plate 52; an adjustment component 53 for adjusting the position of the coarse polishing plate 51 and the fine polishing plate 52; and a drive component 54 for rotating the coarse polishing plate 51 and the fine polishing plate 52.

[0026] The present invention includes a coarse grinding plate 51 and a fine grinding plate 52. When grinding the outer side of the bearing ring, coarse grinding is required first, followed by fine grinding. The goal of the coarse grinding stage is to quickly remove larger unevenness on the surface of the bearing ring. The goal of the fine grinding stage is to further improve the smoothness and precision of the bearing ring surface and remove minor imperfections left by the coarse grinding stage in order to achieve a more refined surface treatment.

[0027] Multiple sets of coarse grinding plates 51 and fine grinding plates 52 are provided to improve the grinding efficiency on the outer side of the bearing ring; for example, in this embodiment, three sets of coarse grinding plates 51 and fine grinding plates 52 are provided respectively.

[0028] The adjustment assembly 53 includes: a mounting box 531; a circular plate 532 rotatably mounted in the mounting box 531; a power source 533 for rotating the circular plate 532, the power source 533 being fixedly mounted in the mounting box 531; a guide groove 534 and a guide groove 535 formed on the circular plate 532; a connecting rod 536 slidably connected to the guide groove 534 and the guide groove 535 respectively; and a limiting member 537 for limiting the connecting rod 536, with multiple sets of limiting members 537, each corresponding to the coarse grinding plate 51 and the fine grinding plate 52 respectively; both the coarse grinding plate 51 and the fine grinding plate 52 are fixedly connected to the adjacent connecting rod 536.

[0029] like Figure 9 As shown, three sets of guide grooves 534 and 535 are provided, and they are arranged in an arc shape. Guide grooves 534 and 535 are arranged along the circumference of the circular plate 532 and are staggered. The rough grinding plate 51 corresponds to guide groove 534, and the fine grinding plate 52 corresponds to guide groove 535.

[0030] When grinding the outer side of the bearing ring, the coarse grinding plate 51 is first brought close to the bearing ring for coarse grinding, and then the fine grinding plate 52 is brought close to the bearing ring for fine grinding. Therefore, the positions of the coarse grinding plate 51 and the fine grinding plate 52 need to be adjusted.

[0031] like Figure 7 As shown, in the initial state, the three sets of coarse grinding plates 51 are located on the inner side, and the three sets of fine grinding plates 52 are located on the outer side. At this time, coarse grinding can be performed first. After the coarse grinding is completed, the positions of the coarse grinding plates 51 and the fine grinding plates 52 need to be adjusted. At this time, the power source 1 533 is started to drive the circular plate 532 to rotate. The circular plate 532 drives the guide groove 1 534 and the guide groove 2 535 to rotate, which can drive the adjacent connecting plate to move, and then drive the coarse grinding plates 51 and the fine grinding plates 52 to move.

[0032] The limiting component 537 includes: a limiting groove 5373 formed in the mounting box 531; a limiting rod 5372 fixedly installed in the limiting groove 5373; a limiting block 5371 slidably installed on the limiting rod 5372; and the limiting block 5371 is rotatably connected to the adjacent connecting rod 536.

[0033] When the linkage rod 536 moves, it can drive the limiting block 5371 to slide in the limiting groove 5373. The limiting groove 5373 can limit the movement of the limiting block 5371. The limiting rod 5372 can further guide and limit the limiting block 5371, and prevent the limiting block 5371 from separating from the limiting groove 5373.

[0034] When the circular plate 532 rotates, guided by the first guide groove 534 and the second guide groove 535, and limited by the limiting member 537, the rough grinding plate 51 and the fine grinding plate 52 move linearly along the axial direction of the limiting rod 5372.

[0035] Since the arc directions of guide groove 1 534 and guide groove 2 535 are opposite, when the coarse grinding plate 51 moves away from each other, the fine grinding plate 52 moves closer to each other, thereby realizing the adjustment of the position of the coarse grinding plate 51 and the fine grinding plate 52, and thus the outer side of the bearing ring can be coarsely and finely ground, improving the grinding effect of the bearing ring.

[0036] After the fine grinding is completed, the power source 533 is started to drive the circular plate 532 to rotate in the opposite direction, thereby resetting the coarse grinding plate 51 and the fine grinding plate 52 to their initial state.

[0037] It should be noted that the preferred power source 533 is an electric motor.

[0038] The drive assembly 54 includes: a second power source 542 fixedly installed in the mounting bracket 2; a movable plate 541 fixedly installed at the movable end of the second power source 542; a rotating tube 543 rotatably installed on the movable plate 541; a driven gear 544 fixedly sleeved on the rotating tube 543; a driving gear 545 meshing with the driven gear 544; a third power source 546 driving the driving gear 545 to rotate; and the rotating tube 543 fixedly connected to the mounting box 531.

[0039] When grinding the outer side of the bearing ring, power source 2 542 is started to drive the movable plate 541 to move downward, thereby driving the coarse grinding plate 51 and the fine grinding plate 52 to adjust their height, so that the coarse grinding plate 51 and the fine grinding plate 52 move to the required height. At this time, power source 3 546 is started to drive the rotating tube 543 to rotate, and the rotating tube 543 drives the mounting box 531 to rotate, thereby driving the coarse grinding plate 51 and the fine grinding plate 52 to rotate, thus realizing the coarse grinding and fine grinding of the bearing ring.

[0040] It should be noted that power source 2 542 is preferably a cylinder; power source 3 546 is preferably an electric motor.

[0041] The cooling mechanism 6 includes: an annular plate 61 fixedly installed on the movable plate 541; a liquid storage shell 62 and a nozzle 63 arranged circumferentially along the annular plate 61; a guide groove 64 opened in the annular plate 61; and a suction assembly 65 for drawing coolant from the liquid storage shell 62 into the nozzle 63.

[0042] The suction assembly 65 includes: a mounting shell 651 fixedly connected to the liquid storage shell 62; a transmission gear 652 rotatably mounted on the mounting shell 651; a rotating plate 653 coaxially connected to the transmission gear 652; a fixing rod 654 fixedly mounted on the rotating plate 653; a linkage frame 655 slidably connected to the fixing rod 654, the linkage frame 655 having a moving groove, the fixing rod 654 slidably mounted in the moving groove; a piston 656 fixedly connected to the linkage frame 655; a fixing pipe 657 fixedly mounted on the mounting shell 651, the piston 656 slidably mounted in the fixing pipe 657; an inlet pipe 658 connected to the liquid storage shell 62 and the fixing pipe 657, the inlet pipe 658 having a first one-way valve installed on it; an outlet pipe 659 connected to the nozzle 63, the fixing pipe 657 having a second one-way valve installed on it.

[0043] The mounting box 531 is fixedly connected to the limiting frame 66. A movable rod 67 is slidably installed inside the limiting frame 66. One end of the movable rod 67 is fixedly connected to the liquid storage shell 62, and the other end of the movable rod 67 is rotatably connected to the nozzle 63.

[0044] When the bearing ring is being polished, the synchronous cooling mechanism 6 can cool the polished area of ​​the bearing ring. That is, the power source 3 546 drives the rotating tube 543 to rotate, the rotating tube 543 drives the mounting box 531 to rotate, the mounting box 531 drives the limiting frame 66 to rotate, the limiting frame 66 drives the movable rod 67 to rotate, thereby driving the nozzle 63 and the liquid storage shell 62 to rotate, and the liquid storage shell 62 drives the mounting shell 651 to rotate, thereby causing the transmission gear 652 and the nozzle 63 to rotate circumferentially along the annular plate 61.

[0045] The guide groove 64 is an annular groove with a uniform waveform, and a toothed block (not shown) is fixedly installed inside the guide groove 64. The transmission gear 652 and the toothed block are meshed with each other. Since the toothed block is located at the bottom of the inner cavity of the guide groove 64, the transmission gear 652 is always meshed with the toothed block under the action of gravity. When the transmission gear 652 moves along the path of the annular groove, it moves up and down while rotating around the circumference of the annular plate 61 and rotating on its own axis.

[0046] When the transmission gear 652 rotates, it drives the rotating plate 653 to rotate. The rotating plate 653 drives the fixed rod 654 to move, and the fixed rod 654 drives the linkage frame 655 to move. The linkage frame 655 drives the piston 656 to move up and down reciprocally within the fixed tube 657. When the piston 656 moves upward, the first one-way valve closes and the second one-way valve opens, and the coolant in the reservoir 62 is drawn into the fixed tube 657 through the inlet pipe 658. When the piston 656 moves downward, the first one-way valve opens and the second one-way valve closes, and the coolant in the fixed tube 657 is squeezed and transported through the reservoir pipe to the nozzle 63, where it is sprayed onto the outside of the bearing ring. This cools the bearing ring at the grinding point, preventing excessive temperature during grinding and deformation of the bearing ring's outer wall, thus protecting the outer wall from heat damage and improving grinding efficiency and quality. Furthermore, the sprayed coolant cleans away debris, dust, and stains generated during grinding, keeping the outer wall of the bearing ring clean and further improving its quality and appearance.

[0047] At the same time, as the transmission gear 652 moves along the path of the guide groove 64, the mounting shell 651 rotates and moves up and down in a circumferential direction, thereby driving the movable rod 67 to rotate and move up and down in a circumferential direction, which in turn drives the nozzle 63 to rotate and move up and down in a circumferential direction. This makes the nozzle 63 spray a wide range, so that the outer wall of the bearing ring is fully sprayed with coolant, which enhances the effect of cooling the outer wall of the bearing ring and cleaning the debris, dust and stains generated during the polishing process.

[0048] In this invention, the power source 546 is activated, which drives the coarse grinding plate 51 and the fine grinding plate 52 to rotate and grind the bearing ring. At the same time, the coolant in the liquid storage shell 62 is delivered to the nozzle 63 and sprayed on the grinding area of ​​the bearing ring, so that grinding and cooling are carried out simultaneously, thereby achieving timely cooling during the grinding of the bearing ring.

[0049] The cooling mechanism 6 also includes: a swing assembly 68 that drives the nozzle 63 to swing; the swing assembly 68 includes: a connecting plate 681 fixedly connected to the linkage frame 655; a movable groove 682 opened on the connecting plate 681; and the nozzle 63 is slidably installed in the movable groove 682.

[0050] While the movable frame drives the piston 656 to move up and down, it can also drive the connecting plate 681 to move up and down. Since the movable groove 682 is S-shaped, when the connecting plate 681 moves up and down, the liquid inlet end of the nozzle 63 moves along the path of the movable groove 682, causing the nozzle 63 to swing around the rotation point of the movable rod 67, thereby further expanding the spraying range of the nozzle 63. This allows the nozzle 63 to cool the bearing ring comprehensively on the one hand, and to cool the rough grinding plate 51 and the fine grinding plate 52 comprehensively on the other hand.

[0051] The cooling mechanism 6 further includes: a replenishing component 69 for replenishing coolant into the liquid storage tank 62; the replenishing component 69 includes: a liquid storage tank 694 fixedly installed on the machine base 1; a liquid collection pipe 693 fixedly installed on the mounting box 531; a fixed cylinder 695 fixedly installed on the mounting frame 2; a sliding plate 696 slidably installed inside the fixed cylinder 695; a bladder 697 fixedly installed between the sliding plate 696 and the fixed cylinder 695; an inlet pipe 691 connecting the bladder 697 and the liquid storage tank 694, with a third check valve installed on the inlet pipe 691; an outlet pipe 692 connecting the bladder 697 and the liquid collection pipe 693, with a fourth check valve installed on the outlet pipe 692; a guide pipe 698 connecting the liquid collection pipe 693 and the liquid storage tank 62; the liquid collection pipe 693 is rotatably connected to the sliding plate 696, rotatably connected to the outlet pipe 692, and slidably connected to the fixed cylinder 695.

[0052] When the second power source 542 drives the movable plate 541 to move downward, it can drive the mounting box 531 to move downward. The mounting box 531 drives the liquid collection pipe 693 to move downward, the liquid collection pipe 693 drives the sliding plate 696 to move downward, and the sliding plate 696 drives the bladder 697 to return to its original position. When the bladder 697 returns to its original position, it generates suction. At this time, the third one-way valve opens and the fourth one-way valve closes. The coolant in the storage tank 694 enters the bladder 697 through the feed pipe 691.

[0053] When the second power source 542 drives the movable plate 541 to move upward, it can drive the mounting box 531 to move upward. The mounting box 531 drives the liquid collecting pipe 693 to move upward, the liquid collecting pipe 693 drives the sliding plate 696 to move upward, and the sliding plate 696 drives the bladder 697 to squeeze, thereby squeezing the coolant in the bladder 697. At this time, the third one-way valve is closed and the fourth one-way valve is opened. The coolant in the bladder 697 enters the liquid collecting pipe 693 through the discharge pipe 692 and enters the liquid storage shell 62 through the liquid guide pipe 698, preparing for subsequent use.

[0054] By adding component 69, the coolant in the reservoir 62 is automatically replenished without manual replenishment, thus improving the automation level of the device.

[0055] The adjustment assembly 53 also includes a flipping unit 538 for flipping the coarse grinding plate 51 and the fine grinding plate 52; the flipping unit 538 includes a slide groove 5381 opened on the mounting box 531; a slider 5382 and a connecting gear 5383 fixedly sleeved on the connecting rod 536; a rack 5384 fixedly installed on the mounting box 531; the slider 5382 is slidably installed in the slide groove 5381.

[0056] The slide groove 5381 is matched with the slider 5382 near both ends, thereby limiting the slider 5382. The width of the slide groove 5381 near the middle is wider than that at both ends, so that the slider 5382 is not restricted when rotating near the middle of the slide groove 5381.

[0057] When the coarse grinding plate 51 and the fine grinding plate 52 are adjusted in position, that is, when the coarse grinding plate 51 is finished and needs to be adjusted in position with the fine grinding plate 52, the connecting rod 536 located in the first guide groove 534 drives the coarse grinding plate 51 to move, so that the coarse grinding plates 51 move away from each other. At the same time, the connecting rod 536 located in the second guide groove 535 drives the fine grinding plate 52 to move, so that the fine grinding plates 52 move closer to each other.

[0058] When the connecting rod 536 located in the guide groove 534 drives the coarse grinding plate 51 to move, it also drives the adjacent slider 5382 and the connecting gear 5383 to move. When the slider 5382 gradually moves towards the middle of the slide groove 5381, the connecting gear 5383 meshes with the rack 5384, causing the connecting gear 5383 to rotate. After the connecting gear 5383 rotates 180 degrees, it separates from the rack 5384. At this time, the slider 5382 gradually moves towards the end of the slide groove 5381, that is, after the coarse grinding plate 51 rotates 180 degrees, it stops rotating.

[0059] At the same time, the linkage rod 536 located in the guide groove 535 drives the fine grinding plate 52 to move, and through the mutual cooperation of its adjacent linkage gear 5383 and rack 5384, the fine grinding plate 52 is rotated 180 degrees, and the fine grinding plate 52 stops rotating after being rotated 180 degrees.

[0060] After the coarse grinding plate 51 is rotated 180 degrees, its grinding side changes from facing the bearing ring to facing away from the bearing ring. After the fine grinding plate 52 is rotated 180 degrees, its grinding side changes from facing away from the bearing ring to facing the bearing ring. At this time, the bearing ring can be finely ground.

[0061] At this time, the coolant sprayed by the nozzle 63 corresponding to the coarse grinding plate 51 is sprayed onto the grinding side of the coarse grinding plate 51. On the one hand, it can cool down the coarse grinding plate 51 to prepare it for subsequent use. On the other hand, it can wash away the grinding debris attached to the grinding side of the coarse grinding plate 51 to ensure the subsequent grinding effect.

[0062] Similarly, when rough grinding is performed, the nozzle 63 corresponding to the fine grinding plate 52 sprays coolant onto the grinding side of the fine grinding plate 52.

[0063] By cooperating with the flipping unit 538 and the cooling mechanism 6, the bearing ring is cooled at the grinding area, improving the quality and appearance of the bearing ring. On the other hand, the coarse grinding plate 51 or fine grinding plate 52 is rinsed, which cleans the grinding debris attached to the grinding side and ensures the subsequent grinding effect.

[0064] Since the nozzle 63 can move up and down and swing back and forth, the spraying range of the nozzle 63 is increased, which can thoroughly clean the grinding side of the coarse grinding plate 51 or the fine grinding plate 52, thus improving the cleaning effect.
