Description

Technical Field

[0001] The present invention relates specifically to the technical field of bearing processing, in particular to a bearing ring end face filing device. Background Art

[0002] End face grinding of bearing inner rings during machining is a critical process for ensuring ultimate precision, performance, and assembly reliability. The end face of the bearing inner ring (especially the end face that contacts the bearing seat or retaining ring) is a critical assembly reference surface. Grinding can achieve end face flatness errors within 0.001-0.005mm (depending on the precision level) through high-speed grinding wheel rotation (typically 1000-3000 r / min) and micro-cutting (single feed rate of only 0.001-0.01mm). This accuracy is far superior to that of other machining methods such as filing and turning (turning flatness is generally 0.01-0.05mm). If the end face is uneven, the inner ring will contact adjacent parts (such as the bearing seat and gasket) with "point contact" rather than "surface contact" during assembly, resulting in uneven force and increased localized wear or deformation.

[0003] Chinese patent publication number CN221582240U discloses a bearing grinder for bearing processing, comprising a base, a bearing ring being placed on the surface of the base, a first convex shaft being fixed on the surface of the base, a pipe joint being sleeved on the outer surface of the first convex shaft, a folded scraper being fixed on one side of the pipe joint, a scraper being sleeved on the outer surface of the folded scraper, and a second folded scraper being fixed on the surface of the folded scraper.

[0004] The bearing grinder in the above patent is a device that rotates the angled scraper and the scraper by toggling the torsion block, which can rotate and scrape the burrs on the end face, outer side and inner side of the bearing ring. The burrs are scraped off comprehensively. After the burrs on one end of the bearing ring are scraped off, it needs to be removed and flipped to the other side to deburr. It is impossible to achieve simultaneous grinding of both ends of the ring. This requires the equipment to be shut down for operation, and to be re-clamped and re-positioned. It is impossible to achieve continuous grinding of the bearing ring. Frequent starting and stopping of the equipment will also reduce the service life of the equipment. Summary of the Invention

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1 to 14 In an embodiment of the present invention, a bearing ring end face filing device includes a conveyor 1 for conveying bearing rings, a ring adjustment robot 2 is installed above one end of the conveyor 1, and a loading assembly 3 for placing the bearing rings on a rotating disk 11 is provided on one side of the other end of the conveyor 1; The rotating disk 11 is disposed within the frame 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 slide 52 and an upper slide 54 slidably connected to a first guide rod 51. A grinding motor 513 is fixed to the bottom of the bottom slide 52. A gear shaft 511 is fitted on the output shaft of the grinding motor 513. A lower grinding ring 512 is fitted on the outer side of the gear shaft 511 in an interference fit. A rotating gear ring 58 is rotatably connected to the middle position of the bottom of the upper slide plate 54 ; an upper grinding member 59 is installed on the outer side of the rotating gear ring 58 in an interference fit.

[0032] By adopting the above technical solution, when in use, the processed bearing rings are placed at one time or placed on the conveyor 1 using a discharge machine. When the bearing rings pass through the ring adjustment robot 2, the ring adjustment robot 2 corrects the position of the bearing rings. As the conveyor 1 transmits the bearing rings, when they are transferred to the loading assembly 3, the loading assembly 3 places the bearing rings on the rotating disk 11.

[0033] The setting of the above mechanism can realize the function of uninterrupted loading and placement of bearing rings without manual intervention, which greatly improves the working efficiency of the equipment.

[0034] As a further explanation of the above embodiment, a plurality of circular grooves are provided on the rotating disk 11, in which a fixing ring 13 is fixed by countersunk bolts. A plurality of trapezoidal teeth 14 are arranged in a circular array on the inner side of the fixing ring 13 for facilitating 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 the multiple trapezoidal teeth 14 and then 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 that of the trapezoidal teeth 14 , so that both the upper and lower surfaces of the bearing ring are exposed during press-fitting, which facilitates the processing of the end face of the bearing ring.

[0037] Please see the attached Figure 3 、 Figure 10 and Figure 13 In this embodiment, both ends of the first guide rod 51 are fixed to the frame body 4; two lifting cylinders 53 are provided below the bottom slide 52 and are fixed to the cylinder rods of the lifting cylinders 53; Two lifting cylinders 55 are provided above the upper slide 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 side slide 52 upward, the gear shaft 511 passes through the bearing ring, and the lower grinding ring 512 is attached to the lower end surface of the bearing ring; The lifting cylinder 55 pushes the upper slide 54 downward, and the rotating gear ring 58 is sleeved on the gear shaft 511, so that the upper grinding member 59 fits on the upper end surface 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 member 59 grind the two ends of the bearing ring simultaneously.

[0039] When the bearing ring is being ground, there is no need to disassemble it and re-clamp it, and there is no need to stop the machine, which effectively improves the processing efficiency of the bearing ring.

[0040] In this embodiment, the upper grinding member 59 has a circular portion, and a protrusion is integrally provided on one side of the circular portion; the diameter of the circular 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 arranged in a C-shape, and the width of the C-shaped opening of the pressure ring 57 is smaller than the width of the raised portion; A positioning sensor 510 is provided above the C-shaped opening of the pressure ring 57 and is embedded in the upper slide 54. The positioning sensor 510 is provided to ensure that the raised portion of the upper grinding member 59 is exactly at the C-shaped opening of the pressure ring 57, thus ensuring the normal expansion and contraction of the upper grinding member 59.

[0041] As a further explanation of this embodiment, the pressure ring 57 is provided to press the bearing ring between the plurality of trapezoidal teeth 14 for fixation; the pressure ring 57 is driven by the pressing cylinder 56, thereby facilitating the application of force and compression to the bearing ring; The pressure ring 57 has a C-shaped notch to facilitate the extension and contraction of the upper grinding member 59; the setting of the raised portion of the upper grinding member 59 is capable of completely covering the end face of the bearing ring and grinding it to ensure the flatness of the bearing ring.

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

[0043] Specifically, the upper finishing assembly 61 and the lower finishing assembly 62 each include a sliding carrier 64 slidably connected to the second guide rod 63. A three-jaw chuck 67 is provided on the side of the sliding carrier 64 close to 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 64. The three-jaw chuck 67 is equipped with a finishing tool disc 68 .

[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 fine turning; for this purpose, we set up an upper fine-tuning component 61 and a lower fine-tuning component 62 to fine-tune 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 fine-trimmed, the driving cylinder 65 pushes the sliding carrier 64 along the second guide rod 63 to approach the side of the bearing ring, and the driving motor 66 drives the three-jaw chuck 67 equipped with a fine-trimming cutter disc 68 to rotate at high speed, and fine-trims the end face of the bearing ring, thereby ensuring the flatness and processing accuracy of the end face of the bearing ring.

[0046] Please see the attached Figure 10 In this embodiment, a ring unloading mechanism 7 is further provided on one side of the rotating disk 11, and the ring unloading mechanism 7 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, and 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 end of the guide column 71 is slidingly connected to the frame body 4; the bottom of the lifting plate 73 passes through two fixed plates 75; the inner side of the fixed plate 75 is fixed with a ring removal piece 76.

[0047] For more details, please refer to the attached Figure 12 The ferrule removal member 76 includes a conical cylinder 761, which is provided with a plurality of rectangular grooves around it, and a movable clamping seat 762 is provided in the rectangular grooves; the lower end of the movable clamping seat 762 is movably connected to the conical cylinder 761 through a rotating shaft, and the upper end of the inner side of the movable clamping seat 762 is movably connected to a connecting rod through a rotating shaft, and the connecting rod is movably connected to the sliding ring 763 through the rotating shaft; The sliding ring 763 is slidably connected to the sliding rod 766 , and the lower end of the sliding rod 766 is fixed to the conical cylinder 761 .

[0048] By adopting the above technical solution, when removing the processed bearing ring, the cylinder rod of the adjustment cylinder 72 is extended, pushing the lifting plate 73 downward, so that the ring removal piece 76 enters the interior of the bearing ring, and when the movable clamping seat 762 contacts the inner ring of the bearing, it will flip inward; after the movable clamping seat 762 passes through the bearing ring, the movable clamping seat 762 flips to the outside of the conical cylinder 761, and at this time the cylinder rod of the adjustment cylinder 72 contracts, driving the lifting plate 73 to move upward, and the multiple movable clamping seats 762 are clamped to the bottom of the bearing ring; thereby, the bearing ring can be separated from between the multiple trapezoidal clamping 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 through a plurality of support rods, and the connecting ring 764 is slidingly connected to the T-rod 765, wherein the upper end of the T-rod 765 is fixed to the cylinder rod of the unloading cylinder 77; the unloading cylinder 77 is fixed on the lifting plate 73.

[0050] By adopting the above technical solution, after the bearing ring is taken out from between the multiple trapezoidal teeth 14, the cylinder rod of the unloading cylinder 77 contracts, and the connecting ring 764 drives the sliding ring 763 to slide upward along the sliding rod 766 through the support rod, and the multiple movable seats 762 contract inward, and the bearing ring can fall off from the conical cylinder 761; at this time, it is only necessary to manually take out the bearing ring.

[0051] In this embodiment, the rotating disk 11 is mounted on the reduction gear unit 12, and the reduction gear unit 12 is fixed with the support frame 10, and the support frame 10 is fixed in the middle position inside the frame body 4; Please see the attached Figures 1 to 7 A power distribution cabinet 8 is fixed on one side of the frame body 4, and an industrial computer 9 is provided above the power distribution cabinet 8; the industrial computer 9 is fixed to the frame body 4.

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

[0053] Please see the attached Figure 1 、 Figure 2 and Figure 9 In this embodiment, the loading assembly 3 includes a vertical bracket 31, a horizontal bracket 32 ​​is vertically fixed to the top of the vertical bracket 31, a horizontal slide rail 33 is fixed to the inner side of the horizontal bracket 32 ​​by a countersunk bolt, and a slide seat 34 is slidably connected to the horizontal slide rail 33; one side of the slide seat 34 is fixed to the cylinder rod of the horizontal sliding cylinder 36; the horizontal sliding cylinder 36 is fixed to the horizontal bracket 32; A vertical double-rod cylinder 35 is fixed to the outside of the slide 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 ring is loaded, the cylinder rod of the vertical double-rod cylinder 35 is extended, and the bearing ring is clamped by the mechanical clamp 37. Then the cylinder rod of the vertical double-rod cylinder 35 is retracted, and the cylinder rod of the horizontal sliding cylinder 36 is extended, driving the slide 34 to move along the horizontal slide rail 33 toward the end of the rotating disk 11. Then the cylinder rod of the vertical double-rod cylinder 35 is extended, and the mechanical clamp 37 places the bearing ring between the multiple trapezoidal teeth 14; thereby, the equipment can be continuously and uninterruptedly loaded, and the working efficiency of the equipment is effectively improved.

[0055] The working principle of the present invention is as follows: when in use, the processed bearing rings are placed at one time or placed on the conveyor 1 by the discharging machine. When the bearing ring passes through the ring adjusting manipulator 2, the ring adjusting manipulator 2 corrects the position of the bearing ring. As the conveyor 1 is transported, when the bearing ring is transported to the feeding assembly 3, the cylinder rod of the vertical double-rod cylinder 35 is extended, and the bearing ring is clamped by the mechanical clamp 37. Then the cylinder rod of the vertical double-rod cylinder 35 is retracted, and the cylinder rod of the horizontal sliding cylinder 36 is extended, driving the slide 34 to move along the horizontal slide rail 33 toward the end of the rotating disk 11. Then the cylinder rod of the vertical double-rod cylinder 35 is extended, and the mechanical clamp 37 places the bearing ring between the multiple trapezoidal teeth 14; thereby realizing continuous and uninterrupted feeding of the equipment; the speed reducer unit 12 drives the rotating disk 11 to rotate, and when the bearing ring rotates to the ring filing mechanism 5; The lifting cylinder 53 pushes the bottom slide 52 upward, and the gear shaft 511 penetrates the bearing ring, so that the lower grinding ring 512 is in contact with the lower end surface of the bearing ring; the pulling cylinder 55 pushes the upper slide 54 downward, and the rotating gear ring 58 is sleeved on the gear shaft 511, so that the upper grinding member 59 is in contact with the upper end surface 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 member 59 grind both ends of the bearing ring simultaneously; The speed reducer 12 drives the rotating disk 11 to rotate. When the bearing ring rotates to the ring finishing mechanism 6, the driving cylinder 65 pushes the sliding carrier 64 along the second guide rod 63 to the side of the bearing ring. The driving motor 66 drives the three-jaw chuck 67 equipped with the finishing cutter 68 to rotate at high speed and perform finishing processing on the end face of the bearing ring, thereby ensuring the flatness and processing accuracy of the end face of the bearing ring. The reduction gear unit 12 drives the rotating disk 11 to rotate. When the bearing ring rotates to the ring unloading mechanism 7, the cylinder rod of the adjustment cylinder 72 is extended to push the lifting plate 73 to move downward, so that the ring removal piece 76 enters the interior of the bearing ring. When the movable clamping seat 762 contacts the inner ring of the bearing, it will flip inward; after the movable clamping seat 762 passes through the bearing ring, the movable clamping seat 762 flips to the outside of the conical cylinder 761. At this time, the cylinder rod of the adjustment cylinder 72 is contracted, driving the lifting plate 73 to move upward. The movable clamping seat 762 is locked to the bottom of the bearing ring; thus, the bearing ring can be disengaged from between the multiple trapezoidal teeth 14, thereby realizing the function of removing the bearing ring; after the bearing ring is removed from between the multiple trapezoidal teeth 14, the cylinder rod of the unloading cylinder 77 is retracted, and the connecting ring 764 drives the sliding ring 763 to slide upward along the sliding rod 766 through the support rod, and the multiple movable clamping seats 762 are retracted inwardly, and the bearing ring can fall off from the tapered cylinder 761; at this time, it is only necessary to manually remove the bearing ring.
