Description

Technical Field

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

[0002] The end face grinding of the bearing inner ring during machining is a crucial process to ensure its final accuracy, performance, and assembly reliability. The end face of the bearing inner ring (especially the end face that contacts the bearing housing or retaining ring) is an important assembly reference surface. Grinding, through the high-speed rotation of the grinding wheel (typically 1000-3000 r / min) and micro-cutting (single feed amount only 0.001-0.01 mm), can control the flatness error of the end face within 0.001-0.005 mm (depending on the precision grade), which is far higher than the precision of filing, turning, and other machining methods (turning flatness is generally 0.01-0.05 mm). If the end face is not flat, during assembly, the inner ring will have "point contact" rather than "surface contact" with adjacent parts (such as bearing housing and gaskets), resulting in uneven stress and aggravating local wear or deformation.

[0003] Chinese Patent Publication No. CN221582240U discloses a bearing grinder for bearing processing, including a base, a bearing ring placed on the surface of the base, a first convex shaft fixed on the surface of the base, a pipe head sleeved on the outer surface of the first convex shaft, a bend scraper fixed on one side of the pipe head, a scraper sleeved on the outer surface of the bend scraper, and a second convex shaft fixed on the surface of the bend scraper.

[0004] The bearing grinder in the aforementioned patent uses a torsion block to rotate a folding scraper and the scraper itself to remove burrs from the end face, outer side, and inner side of the bearing ring. While the scraping is thorough, after removing burrs from one end of the bearing ring, it needs to be removed and flipped to the other side for further deburring. This prevents simultaneous grinding of both ends of the ring, necessitating equipment shutdown and re-clamping and repositioning. Continuous grinding of the bearing ring is also impossible, and frequent start-ups and shutdowns reduce the equipment's lifespan. Summary of the Invention

[0005] The purpose of this invention is to provide a bearing ring end face filing device that can simultaneously grind both ends of the bearing ring without stopping the machine, without manual intervention, and can continuously process the bearing ring, greatly improving the working efficiency of the bearing ring; thus solving the technical problems mentioned in the background art.

A rotating gear ring is rotatably connected to the middle position of the bottom of the upper slide plate; an upper grinding component is installed on the outer side of the rotating gear ring with an interference fit.

[0007] As a further technical solution of the present invention, the two ends of the first guide rod are fixed to the frame body; two lifting cylinders are provided below the bottom side slide plate and are fixed to the cylinder rods of the lifting cylinders; Two lifting cylinders are provided above the upper sliding plate; the lifting cylinders are fixed to the frame body, and the cylinder rods of the lifting cylinders are fixed to the frame body.

[0008] As a further technical solution of the present invention, a ring finishing mechanism is provided on the side of the frame away from the conveyor; the ring finishing mechanism includes two second guide rods fixed to the frame, and an upper finishing component and a lower finishing component are slidably connected on the second guide rods; The upper finishing component and the lower finishing component are composed of the same structure and are arranged symmetrically.

[0009] As a further technical solution of the present invention, both the upper finishing component and the lower finishing component include a sliding carrier plate that is slidably connected to the second guide rod. The sliding carrier plate is provided with a three-jaw chuck on the side near the rotating disk. The three-jaw chuck is connected to the drive motor. The drive motor is fixed to the sliding carrier plate. A finishing cutter head is fitted onto the three-jaw chuck.

[0010] The ring unloading mechanism includes two adjusting cylinders fixed to the frame body, and the cylinder rods of the two adjusting cylinders are fixedly connected to the lifting plate; guide columns are also fixed at both ends of the lifting plate; the upper ends of the guide columns are slidably connected to the frame body; a fixed plate is connected to the bottom of the lifting plate through two hanging rods; and a ring removal component is fixed inside the fixed plate.

[0011] As a further technical solution of the present invention, the ring removal component includes a conical cylinder with multiple rectangular grooves around its perimeter and a movable retainer within each rectangular groove. The lower end of the movable retainer is movably connected to the conical cylinder via a rotating shaft, and a connecting rod is movably connected to the upper inner side of the movable retainer via a rotating shaft. The connecting rod is movably connected to a sliding ring via a rotating shaft.

[0012] As a further technical solution of the present invention, the upper end of the sliding ring is connected to a connecting ring by multiple support rods, and the connecting ring is slidably connected to the T-shaped rod, wherein the upper end of the T-shaped rod is fixed to the cylinder rod of the unloading cylinder; the unloading cylinder is fixed to the lifting plate.

[0013] As a further technical solution of the present invention, the feeding assembly includes a vertical support, a horizontal support is vertically fixed to the top of the vertical support, and a transverse slide rail is fixed to the inner side of the horizontal support by countersunk bolts.

In this invention, when the end face of the bearing ring is being finely finished, the drive cylinder pushes the sliding plate along the second guide rod toward the bearing ring side, and the drive motor drives the three-jaw chuck equipped with the fine-finishing cutter disc to rotate at high speed, thereby performing fine-finishing treatment on the end face of the bearing ring, thus ensuring the flatness and processing accuracy of the bearing ring end face. 3. In this invention, when removing the processed bearing ring, the cylinder rod of the adjusting cylinder extends, pushing the lifting plate downward, so that the removed ring enters the interior of the bearing ring. When the movable retainer contacts the inner ring of the bearing, it flips inward; after the movable retainer passes through the bearing ring, it flips to the outside of the conical cylinder. At this time, the cylinder rod of the adjusting cylinder retracts, driving the lifting plate upward, and the multiple movable retainers lock onto the bottom of the bearing ring; thus, the bearing ring can be disengaged from between the multiple trapezoidal retaining teeth, thereby realizing the function of removing the bearing ring.

Detailed Implementation

[0030] 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.

[0031] Please see Figures 1 to 14 In this embodiment of the invention, a bearing ring end face filing device includes a conveyor 1 for conveying bearing rings, a ring adjusting manipulator 2 is installed above one end of the conveyor 1, and a feeding assembly 3 for placing bearing rings onto a rotating disk 11 is provided on one side of the other end of the conveyor 1. The rotating disk 11 is located inside the frame body 4, and a ring filing mechanism 5 is provided on one side of the rotating disk 11. The ring filing mechanism 5 includes a bottom sliding plate 52 and an upper sliding plate 54 slidably connected to the first guide rod 51. A grinding motor 513 is fixed at the bottom of the bottom sliding plate 52, and a gear shaft 511 is fitted on the output shaft of the grinding motor 513. A lower grinding ring 512 is installed on the outer side of the gear shaft 511 with an interference fit. A rotating gear ring 58 is rotatably connected to the middle position of the bottom of the upper sliding plate 54; an upper grinding part 59 is installed on the outer side of the rotating gear ring 58 with an interference fit.

[0032] By adopting the above technical solution, when in use, the processed bearing rings are placed on the conveyor 1 in one go or placed on the conveyor 1 using a feeding machine. When the bearing rings pass through the ring adjusting robot 2, the ring adjusting robot 2 will straighten the position of the bearing rings. As the conveyor 1 transmits, the bearing rings are transmitted to the feeding component 3, where the feeding component 3 places the bearing rings onto the rotating disk 11.

[0033] The aforementioned mechanism enables uninterrupted feeding and placement of bearing rings without manual intervention, greatly improving the equipment's working efficiency.

[0034] As a further explanation of the above embodiment, the rotating disk 11 is provided with multiple circular grooves, and a fixing ring 13 is fixed in the circular grooves by countersunk bolts. The inner side of the fixing ring 13 is arranged in a circular array with multiple trapezoidal teeth 14 to facilitate the fixing of the bearing ring. The trapezoidal teeth 14 are fixed to the fixing ring 13 by countersunk bolts.

[0035] When the bearing ring is placed between multiple trapezoidal teeth 14, and then the bearing ring is pressed down, the bearing ring can be pressed tightly between the multiple trapezoidal teeth 14, thereby achieving the clamping and fixing of the bearing ring.

[0036] It should be noted that the thickness of the bearing ring is greater than the thickness of the trapezoidal tooth 14. During press fitting, both the upper and lower surfaces of the bearing ring are exposed, which facilitates the machining of the bearing ring end face.

[0037] Please see the appendix Figure 3 , Figure 10 and Figure 13 In this embodiment, the two ends of the first guide rod 51 are fixed to the frame body 4; two lifting cylinders 53 are provided below the bottom sliding plate 52 and are fixed to the cylinder rods of the lifting cylinders 53. Two lifting cylinders 55 are provided above the upper sliding plate 54; the lifting cylinders 55 are fixed to the frame body 4, and the cylinder rods of the lifting cylinders 55 are fixed to the frame body 4.

[0038] By adopting the above technical solution, when grinding the bearing ring, the lifting cylinder 53 pushes the bottom slide plate 52 upward, and the gear shaft 511 passes through the bearing ring, so that the lower grinding ring 512 fits against the lower end face of the bearing ring. The lifting cylinder 55 pushes the upper slide plate 54 down, and the rotating gear ring 58 is sleeved on the gear shaft 511, so that the upper grinding part 59 fits against the upper end face of the bearing ring. After the grinding motor 513 is turned on, the grinding motor 513 drives the rotating gear ring 58 to rotate at high speed through the gear shaft 511. At the same time, the lower grinding ring 512 and the upper grinding part 59 grind both ends of the bearing ring simultaneously.

[0039] During the grinding process, the bearing rings do not need to be disassembled and re-clamped, nor does the machine need to be stopped, which effectively improves the processing efficiency of the bearing rings.

[0040] In this embodiment, the upper grinding part 59 has an annular portion, and a protrusion is integrally provided on one side of the annular portion; the diameter of the annular portion is smaller than the inner diameter of the pressure ring 57; the diameter of the protrusion is larger than the diameter of the bearing ring. The pressure ring 57 is C-shaped, and the width of the C-shaped opening of the pressure ring 57 is smaller than the width of the protrusion. A positioning sensor 510 is provided above the C-shaped opening of the pressure ring 57, and the positioning sensor 510 is embedded in the upper sliding plate 54. The positioning sensor 510 is set to ensure that the protrusion of the upper grinding part 59 is exactly at the C-shaped opening of the pressure ring 57, thus ensuring the normal extension and retraction of the upper grinding part 59.

[0041] As a further explanation of this embodiment, the pressure ring 57 is provided to press the bearing ring into the space between multiple trapezoidal teeth 14 for fixation; the pressure ring 57 is driven by the clamping cylinder 56, which facilitates the application of force and clamping of the bearing ring. The pressure ring 57 has a C-shaped groove to facilitate the extension and retraction of the upper grinding member 59; the protrusion of the upper grinding member 59 is designed to completely cover the end face of the bearing ring during grinding, ensuring the flatness of the bearing ring during grinding.

[0042] Please see the appendix Figure 4 and Figure 11 In this embodiment, the side of the frame body 4 away from the conveyor 1 is provided with a ring finishing mechanism 6; the ring finishing mechanism 6 includes two second guide rods 63 fixed to the frame body 4, and the second guide rods 63 are slidably connected to an upper finishing component 61 and a lower finishing component 62. The upper finishing component 61 and the lower finishing component 62 are composed of the same structure and are arranged symmetrically.

[0043] More specifically, both the upper finishing component 61 and the lower finishing component 62 include a sliding carrier plate 64 that is slidably connected to the second guide rod 63. The sliding carrier plate 64 is provided with a three-jaw chuck 67 on the side near the rotating disk 11. The three-jaw chuck 67 is connected to the drive motor 66. The drive motor 66 is fixed to the sliding carrier plate 64. A finishing cutter head 68 is fitted onto the three-jaw chuck 67.

[0044] If local scratches, chipping, or burns appear on the rear end face of the bearing ring after grinding, and the defect depth is shallow (≤0.05mm), the defect layer can be removed by precision turning. For this purpose, we have set up an upper precision repair component 61 and a lower precision repair component 62 to perform precision repair on the upper and lower end faces of the bearing ring.

[0045] By adopting the above technical solution, when the end face of the bearing ring is being finely finished, the drive cylinder 65 pushes the sliding carrier plate 64 to move closer to the bearing ring side along the second guide rod 63, and the drive motor 66 drives the three-jaw chuck 67, which is equipped with a fine-finishing cutter head 68, to rotate at high speed and perform fine-finishing treatment on the end face of the bearing ring, thereby ensuring the flatness and machining accuracy of the end face of the bearing ring.

[0046] Please see the appendix Figure 10 In this embodiment, a ring unloading mechanism 7 is also provided on one side of the rotary disk 11, which is located on the opposite side of the ring filing mechanism 5. The ring unloading mechanism 7 includes two adjusting cylinders 72 fixed to the frame body 4. The cylinder rods of the two adjusting cylinders 72 are fixedly connected to the lifting plate 73. Guide columns 71 are also fixed at both ends of the lifting plate 73. The upper ends of the guide columns 71 are slidably connected to the frame body 4. The bottom of the lifting plate 73 is connected to a fixed plate 75 through two hanging rods. A ring removal component 76 is fixed inside the fixed plate 75.

[0047] For more details, please refer to the appendix. Figure 12 The ring removal component 76 includes a conical cylinder 761, which has multiple rectangular grooves around its perimeter. A movable retainer 762 is provided in each of the rectangular grooves. The lower end of the movable retainer 762 is movably connected to the conical cylinder 761 via a rotating shaft. A connecting rod is movably connected to the upper inner side of the movable retainer 762 via a rotating shaft. The connecting rod is movably connected to a sliding ring 763 via a rotating shaft. The sliding ring 763 is slidably connected to the slide rod 766, the lower end of which is fixed to the tapered cylinder 761.

[0048] By adopting the above technical solution, when removing the processed bearing ring, the cylinder rod of the adjusting cylinder 72 extends, pushing the lifting plate 73 downward, so that the ring removal part 76 enters the bearing ring. When the movable retainer 762 contacts the inner ring of the bearing, it will flip inward. After the movable retainer 762 passes through the bearing ring, the movable retainer 762 flips to the outside of the conical cylinder 761. At this time, the cylinder rod of the adjusting cylinder 72 retracts, driving the lifting plate 73 to move upward. The multiple movable retainers 762 lock onto the bottom of the bearing ring. Thus, the bearing ring can be disengaged from the multiple trapezoidal retaining teeth 14, thereby realizing the function of removing the bearing ring.

[0049] Furthermore, the upper end of the sliding ring 763 is connected to a connecting ring 764 via multiple support rods. The connecting ring 764 is slidably connected to the T-shaped rod 765, wherein the upper end of the T-shaped rod 765 is fixed to the cylinder rod of the unloading cylinder 77; the unloading cylinder 77 is fixed to the lifting plate 73.

[0050] By adopting the above technical solution, after the bearing ring is removed from between the multiple trapezoidal teeth 14, the cylinder rod of the unloading cylinder 77 retracts, and the connecting ring 764 drives the sliding ring 763 to slide upward along the sliding rod 766 through the support rod. The multiple movable seats 762 retract inward, and the bearing ring can fall off from the conical cylinder 761. At this time, the bearing ring can be removed manually.

[0051] In this embodiment, the rotary disk 11 is fitted onto the reducer unit 12, and the reducer unit 12 is fixedly mounted with a support frame 10, which is fixed in the middle position inside the frame body 4. Please see the appendix Figures 1 to 7 A power distribution cabinet 8 is fixed on one side of the frame body 4, and an industrial control computer 9 is provided above the power distribution cabinet 8; the industrial control computer 9 is fixed to the frame body 4.

[0052] The power distribution cabinet 8 is used for power distribution to various mechanisms, and the industrial control computer 9 controls the coordinated work of various mechanisms. The industrial control computer 9 has built-in programs that can be set according to the required actions. The control method based on the industrial control computer is existing technology, so its working principle will not be described in detail.

[0053] Please see the appendix Figure 1 , Figure 2 and Figure 9 In this embodiment, the feeding assembly 3 includes a vertical support 31, a horizontal support 32 is vertically fixed to the top of the vertical support 31, and a transverse slide rail 33 is fixed to the inner side of the horizontal support 32 by countersunk bolts. A slide block 34 is slidably connected to the transverse slide rail 33. One side of the slide block 34 is fixed to the cylinder rod of the transverse sliding cylinder 36. The transverse sliding cylinder 36 is fixed to the horizontal support 32. A vertical double-rod cylinder 35 is fixed to the outside of the slide block 34, and a mechanical gripper 37 is fixed to the end of the cylinder rod of the vertical double-rod cylinder 35.

[0054] By adopting the above technical solution, when the bearing rings are being fed, the cylinder rod of the vertical double-rod cylinder 35 extends and the mechanical gripper 37 clamps the bearing rings. Then, the cylinder rod of the vertical double-rod cylinder 35 retracts, and the cylinder rod of the transverse sliding cylinder 36 extends, driving the slide block 34 to move along the transverse slide rail 33 towards the end of the rotating disk 11. Then, the cylinder rod of the vertical double-rod cylinder 35 extends, and the mechanical gripper 37 places the bearing rings between multiple trapezoidal teeth 14. This achieves continuous and uninterrupted feeding of the equipment, effectively improving the working efficiency of the equipment.

[0055] The working principle of this invention is as follows: During use, the processed bearing rings are placed on the conveyor 1 in one go or by using a feeding machine. When the bearing rings pass the ring adjusting robot 2, the ring adjusting robot 2 straightens the position of the bearing rings. As the bearing rings are transported by the conveyor 1 to the feeding assembly 3, the cylinder rod of the vertical double-rod cylinder 35 extends and the mechanical gripper 37 clamps the bearing rings. Then the cylinder rod of the vertical double-rod cylinder 35 retracts, and the cylinder rod of the horizontal sliding cylinder 36 extends, driving the slide 34 to move along the horizontal slide rail 33 towards the end of the rotating disk 11. Then the cylinder rod of the vertical double-rod cylinder 35 extends, and the mechanical gripper 37 places the bearing rings between multiple trapezoidal teeth 14; thus, the equipment achieves continuous and uninterrupted feeding. The reducer unit 12 drives the rotating disk 11 to rotate. When the bearing rings rotate to the ring filing mechanism 5; Lifting cylinder 53 pushes the bottom slide plate 52 upward, and the gear shaft 511 passes through the bearing ring, so that the lower grinding ring 512 fits against the lower end face of the bearing ring; lifting cylinder 55 pushes the upper slide plate 54 downward, and the rotating gear ring 58 is sleeved on the gear shaft 511, so that the upper grinding part 59 fits against the upper end face of the bearing ring; after the grinding motor 513 is turned on, the grinding motor 513 drives the rotating gear ring 58 to rotate at high speed through the gear shaft 511, and at the same time the lower grinding ring 512 and the upper grinding part 59 perform grinding treatment on both ends of the bearing ring simultaneously; The reducer unit 12 drives the rotary disk 11 to rotate. When the bearing ring rotates to the ring finishing mechanism 6, the drive cylinder 65 pushes the sliding carrier plate 64 to move closer to the bearing ring side along the second guide rod 63. The drive motor 66 drives the three-jaw chuck 67, which is equipped with a finishing cutter disc 68, to rotate at high speed and perform finishing treatment on the end face of the bearing ring, thereby ensuring the flatness and machining accuracy of the end face of the bearing ring. The reducer unit 12 drives the rotary disk 11 to rotate. When the bearing ring rotates to the bearing ring unloading mechanism 7, the cylinder rod of the adjusting cylinder 72 extends, pushing the lifting plate 73 downward, so that the bearing ring take-out piece 76 enters the bearing ring. When the movable retainer 762 contacts the inner ring of the bearing, it will flip inward. After the movable retainer 762 passes through the bearing ring, the movable retainer 762 flips to the outside of the conical cylinder 761. At this time, the cylinder rod of the adjusting cylinder 72 retracts, driving the lifting plate 73 to move upward. The movable retainer 762 engages with the bottom of the bearing ring, thereby disengaging the bearing ring from between the multiple trapezoidal retaining teeth 14 and realizing the function of removing the bearing ring. After the bearing ring is removed from between the multiple trapezoidal retaining teeth 14, the cylinder rod of the unloading cylinder 77 retracts, and the connecting ring 764 drives the sliding ring 763 to slide upward along the sliding rod 766 through the support rod. The multiple movable retainers 762 retract inward, and the bearing ring can fall off from the conical cylinder 761. At this time, the bearing ring can be removed manually.
