Description

Technical Field

[0001] This invention relates to the field of bearing manufacturing and processing technology, specifically to a multi-faceted grinding and polishing equipment for bearing production. Background Technology

[0002] In the field of bearing manufacturing and processing technology, traditional bearing multi-face grinding and polishing equipment treats the grinding and polishing of bearing rings as two completely independent processes. This separate processing technology makes it difficult to perform the grinding and polishing of the inner and outer circumferential surfaces of the bearing rings simultaneously on the same machine. During processing, multiple disassembly and assembly operations and adjustments to the clamping references are required. On the one hand, this is cumbersome, increases time costs, and reduces processing efficiency; on the other hand, multiple disassembly and assembly operations cannot guarantee the consistency of the processing references, easily leading to processing errors. Furthermore, when the fixing components of the polishing equipment position and fix the inner ring of the bearing, the clamping action often relies on manual operation. Similarly, the alignment of the bearing loading and the unloading and removal of the finished product also require manual handling by the operator.

[0003] This highly manual labor-dependent model not only significantly increases the workload of operators, but may also affect the stability of workpiece fixation due to uneven manual force and inaccurate positioning, thereby interfering with polishing quality and creating a dual constraint on efficiency and precision.

[0004] To this end, the applicant proposes a multi-faceted grinding and polishing equipment for bearing production, which aims to achieve synchronous grinding and polishing of the inner and outer circumferential surfaces of bearing rings through structural innovation, and integrates automated loading and unloading and precise clamping functions to comprehensively improve the efficiency, precision and automation level of bearing processing. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-faceted grinding and polishing equipment for bearing production, solving the following technical problems: Traditional multi-faceted grinding and polishing equipment for bearings treats the grinding and polishing of bearing rings as two completely independent processes. This separate processing makes it difficult to simultaneously grind and polish the inner and outer circumferential surfaces of the bearing rings on the same machine. During processing, multiple disassembly and assembly operations and adjustments to the clamping references are required. This is cumbersome, increases time costs, and reduces processing efficiency. Furthermore, multiple disassembly and assembly operations cannot guarantee the uniformity of the processing references, easily leading to processing errors. Moreover, when the fixing components of the polishing equipment position and fix the inner ring of the bearing, the clamping action often relies on manual operation.

[0012] As a further aspect of the present invention: an intermittent conveying assembly is provided at the upper end of the base, the intermittent conveying assembly includes a storage cabinet provided on the base, a guide plate is provided at the upper end of the storage cabinet via a vertical plate, baffle plates are symmetrically fixed at both ends of the guide plate, and a rotating shaft is symmetrically rotatably provided at the upper end of the storage cabinet, a transmission wheel is sleeved on the outer surface of each of the two rotating shafts, and the same first toothed conveyor belt is sleeved on the outer surface of the two transmission wheels.

[0013] As a further embodiment of the present invention: a groove is provided at one end of each of the two baffle plates, a block is slidably arranged in the groove, a fixing plate is symmetrically fixed at one end of the guide plate, a top plate is slidably arranged on each of the two fixing plates, and a top block adapted to the top plate is fixedly arranged at the lower end of each of the two baffles.

[0016] The beneficial effects of this invention are: (1) This invention effectively solves the problem of traditional equipment requiring multiple disassemblies and reassemblies for grinding and polishing by using a collaborative design of the inner ring processing component and the outer ring processing component. The inner ring processing component uses a bevel gear transmission to drive multiple arc blocks to adjust synchronously, which can adapt to bearing inner rings of different diameters. The first grinding block and the first polishing wheel on the arc block can simultaneously complete the grinding and polishing of the inner ring. The outer ring processing component adapts to outer rings of different sizes by relative sliding of the arc plate. The second grinding block and the second polishing wheel process the outer ring surface synchronously. The entire processing process does not require multiple disassemblies and reassemblies of the workpiece, which avoids the processing errors caused by frequent adjustment of the clamping reference, ensures the uniformity of the processing reference, significantly shortens the processing cycle, and greatly improves the efficiency and accuracy of bearing production. (2) The present invention features a flat, narrow-mouth design for the storage bin, which orderly conveys the bearings to the guide plate. The intermittent conveying component, driven by the conveying motor, uses gear transmission and a return spring to control the opening and closing of the stop block, achieving intermittent and precise feeding of the bearings. The feeding component uses the alternating meshing of the first and second half gears with the toothed plate to drive the receiving table to move back and forth, stably conveying the bearings to the processing station. The entire loading and unloading process does not require manual alignment and placement of workpieces, which not only reduces the dependence on manual operation and avoids the impact of uneven manual force and inaccurate positioning on the stability of workpiece fixation and polishing quality, but also significantly reduces the labor intensity of operators and further improves the automation level and production stability of the equipment.

[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0023] In the field of bearing manufacturing and processing technology, traditional bearing multi-face grinding and polishing equipment has two major problems. First, grinding and polishing are carried out independently, requiring multiple disassembly and adjustment, which is not only cumbersome and inefficient but also prone to processing errors. Second, positioning, clamping, and loading and unloading rely on manual labor, which increases labor intensity and may affect the stability and polishing quality, ultimately resulting in a dual constraint on efficiency and precision.

[0024] Example 1: Please refer to Figure 1As shown, a multi-faceted grinding and polishing equipment for bearing production includes a base 1. Support frames 2 are symmetrically fixedly arranged on the upper end of the base 1. The same mounting plate 3 is fixedly arranged on the upper end of the two support frames 2. Sliding plates 4 are symmetrically slidably arranged on the upper end of the mounting plate 3. The sliding plates 4 can reciprocate on the mounting plate 3. The sliding drive method can be selected from motor screw drive or cylinder drive.

[0025] If a motor-driven lead screw is used, the specific design is as follows: Motors are symmetrically arranged at both ends of the mounting plate 3, and lead screws are symmetrically rotated within the sliding groove at the upper end of the mounting plate 3; sprockets are installed at one end of the motor and one end of the two lead screws, and multiple sprockets are connected by chain drive; sliders are threaded onto the outer surface of both lead screws, and the upper ends of both sliders are fixed to the lower end of the sliding plate 4. The sliders are slidably arranged within the sliding groove at the upper end of the mounting plate 3. During operation, the motor drives the two lead screws to rotate synchronously through the sprockets and chain, and the lead screws then drive the sliding plate 4 to reciprocate at the upper end of the mounting plate 3 through the sliders. If a cylinder drive is used, the cylinder is fixedly mounted on the mounting plate 3, and the output shaft of the cylinder is fixedly connected to the sliding plate 4.

[0026] For further details, please refer to Figure 1 - Figure 4 As shown, one of the sliding plates 4 is provided with an inner ring processing component 5, and the other sliding plate 4 is provided with an outer ring processing component 6; The inner ring machining assembly 5 includes a first drive motor 51 disposed on one side of the sliding plate 4. The output shaft of the first drive motor 51 extends to a mounting box 52 disposed on the other side of the sliding plate 4. A rotary motor 53 is disposed inside the mounting box 52. A first rotating rod 54 is fixedly disposed at one end of the output shaft of the rotary motor 53. A first bevel gear 55 is fixedly disposed on the outer surface of the first rotating rod 54. A plurality of second bevel gears 56 are meshed around the first bevel gear 55. A threaded sleeve 57 is fixedly disposed at the central axis of each of the plurality of second bevel gears 56. The end of the threaded sleeve 57 away from the second bevel gear 56 extends to the outside of the mounting box 52 and is connected to... The mounting box 52 is rotatably connected, and the threaded sleeve 57 is internally threaded with an adjusting screw 58. One end of each adjusting screw 58 is fixedly provided with an arc-shaped block 59. A telescopic sleeve 510 is provided between the arc-shaped block 59 and the mounting box 52. The telescopic sleeve 510 is used to restrict the adjustment screw 58 from rotating relative to the threaded sleeve 57, so that when the threaded sleeve 57 rotates, the adjusting screw 58 can move along the axial direction of the threaded sleeve 57. The upper ends of each of the multiple arc-shaped blocks 59 are symmetrically provided with first mounting grooves 511. One of the first mounting grooves 511 is provided with multiple first grinding blocks 512, and the other first mounting groove 511 is provided with multiple first polishing wheels 513. In this embodiment, multiple arc-shaped blocks 59 are centered on the axis of the mounting box 52, and the outer arc surface of each arc-shaped block 59 faces the same center. Through this concentric symmetrical structure, it can be ensured that when the adjusting screw 58 extends and retracts synchronously, the inner arc surface of all arc-shaped blocks 59 always forms a complete circular outline, thereby adapting to the processing requirements of inner rings of workpieces with different diameters and ensuring the uniformity of contact between the first grinding block 512 and the first polishing wheel 513 and the inner ring of the workpiece. Both the first grinding block 512 and the first polishing wheel 513 are adapted to the width grinding requirements of the bearing. The first drive motor 51 adopts an adjustable speed drive method, and its rotation number can be precisely set in the initial design stage. During grinding operations, the speed can be adjusted to a lower gear to reduce the contact impact between the first grinding block 512 and the inner ring of the workpiece, reduce vibration and noise during processing, and ensure grinding accuracy. In the polishing stage, the speed can be appropriately increased as needed to improve polishing efficiency and surface finish. The model of the first drive motor 51 can be selected as: HF-KN073J-S100 servo motor. The first drive motor 51 drives the mounting box 52 to rotate as a whole, providing circumferential motion power for the inner ring processing. The rotating motor 53 drives the first bevel gear 55 to rotate through the first rotating rod 54. The first bevel gear 55 is then driven to rotate through gear meshing to the second bevel gear 56 around the perimeter, which drives the threaded sleeve 57 to rotate synchronously. The threaded sleeve 57 drives the arc block 59 to move synchronously closer to or further away from the center with the output shaft of the rotating motor 53 as the center. The concentric symmetrical structure ensures that the inner arc surface of the arc block 59 always forms a complete circular outline, which can be adapted to the inner rings of bearings of different diameters. The first grinding block 512 and the first polishing wheel 513 on the arc block 59 are adapted to the bearing width. During operation, the first drive motor 51 rotates at a low speed during the grinding stage to reduce contact impact and ensure accuracy. During the polishing stage, the rotation speed can be increased to improve efficiency and surface finish, ultimately achieving precise grinding and polishing of the bearing inner ring. The sliding plate 4 moves back and forth to complete the grinding and polishing work.

[0027] For further details, please refer to Figure 4 As shown, the outer ring processing assembly 6 includes a second drive motor 61 mounted on a sliding plate 4. The output shaft of the second drive motor 61 extends to the other side of the sliding plate 4 and a rotating plate 62 is mounted thereon. An arc plate 63 is symmetrically slidably mounted on one side of the rotating plate 62. The two arc plates 63 can achieve relative movement through a cylinder or a motor, a two-way lead screw, and a slider. The two arc plates 63 are centered on the axis of the output shaft of the second drive motor 61, and the inner arc surfaces of each arc plate 63 face the same center. Two second mounting slots 64 are opened on the opposite surfaces of the two arc plates 63. A second grinding block 65 and a second polishing wheel 66 are respectively mounted in the two second mounting slots 64. In this embodiment, the two arc-shaped plates 63 are driven by a cylinder, motor, or bidirectional lead screw in conjunction with a slider, so that they move relative to each other around the center of the motor output shaft until their inner arc surfaces fit against the outer ring workpiece to be processed. At the same time, it can adapt to the processing of bearings of different sizes. The second drive motor 61 provides rotational power, driving the rotating plate 62 and the two symmetrically sliding arc-shaped plates 63 to rotate as a whole. The second grinding block 65 in the second mounting groove 64 on the arc-shaped plate 63 first grinds the surface of the workpiece, and the second polishing wheel 66 then completes the polishing of the workpiece surface simultaneously or subsequently, realizing the automated grinding and polishing of the outer ring workpiece. The second drive motor 61 also adopts an adjustable speed drive method and is the same model as the first drive motor 51.

[0028] Example 2: Based on Example 1, please refer to... Figure 5 As shown, a feeding assembly 7 is provided on one side of the support frame 2. The feeding assembly 7 includes a support plate 71 fixedly mounted on one side of the support frame 2. A conveying motor 72 is fixedly mounted on the upper end of the support plate 71. A drive gear 73 is fixedly sleeved in the middle of the output shaft of the conveying motor 72. A driven gear 74 is meshed on one side of the drive gear 73. The lower end of the driven gear 74 is rotatably connected to the support plate 71 through a shaft. A first half gear 75 is fixedly mounted on the end of the output shaft of the conveying motor 72. A first half gear 75 is fixedly mounted on the upper end of the driven gear 74. A second rotating rod 76 is provided, and a second half gear 77 is fixedly provided at the upper end of the second rotating rod 76. A toothed plate 78 is provided between the first half gear 75 and the second half gear 77, and the first half gear 75 and the second half gear 77 are alternately meshed with the toothed plate 78. A sliding seat is fixedly provided at one end of the mounting plate 3. The lower end of the toothed plate 78 is slidably engaged with the sliding seat. A receiving platform 79 is fixedly provided at the upper end of the toothed plate 78. The middle part of the two sides of the receiving platform 79 is higher and the two ends are lower. Anti-slip strips are provided inside the receiving platform 79. In this embodiment, the conveyor motor 72 drives the output shaft to rotate, causing the drive gear 73 and the first half gear 75 to rotate synchronously. The drive gear 73 meshes with and drives the driven gear 74 and the second rotating rod 76 and the second half gear 77 coaxial with it to rotate. Since the first half gear 75 and the second half gear 77 alternately mesh with the toothed plate 78, and the lower end of the toothed plate 78 is slidably engaged with the sliding seat, the toothed plate 78 makes a reciprocating linear motion along the sliding seat under the meshing transmission, thereby driving the upper receiving platform 79 to move synchronously back and forth. The receiving platform 79 uses a structure that is high in the middle and low at both ends, combined with internal anti-slip strips, to achieve stable receiving and conveying of the bearing workpiece. The bearing is placed on the receiving platform 79. The bearing will not slide left or right within the 9-axis. By calculating the travel route, the first half gear 75 and the second half gear 77 alternately mesh with the toothed plate 78. After the first half gear 75 drives the toothed plate 78 to move forward to achieve feeding, the second half gear 77 drives the toothed plate 78 to move backward to achieve subsequent feeding. When the toothed plate 78 reaches the conveying end point, the inner ring processing component 5 will enclose the inside of the bearing, and the bearing will slide out of the receiving platform 79. The inner ring processing component 5 can clamp and fix the bearing. Then, the outer ring processing component 6 will polish and grind the outer ring. After the outer ring polishing and grinding is completed, the outer ring processing component 6 will clamp the bearing, and the inner ring processing component 5 will start working to complete the inner ring processing of the bearing.

[0029] For further details, please refer to Figure 6 - Figure 9 As shown, an intermittent conveying assembly 8 is provided at the upper end of the base 1. The intermittent conveying assembly 8 includes a storage cabinet 81 mounted on the base 1. Symmetrical vertical plates 82 are arranged at the upper end of the storage cabinet 81. One of the vertical plates 82 has a slot adapted to the toothed plate 78, facilitating the reciprocating movement of the toothed plate 78. The upper ends of both vertical plates 82 are fixedly provided with the same guide plate 83, which is inclined. Symmetrical baffle plates 84 are fixedly provided at both ends of the guide plate 83. One of the baffle plates 84 has a through hole in its center. The storage cabinet 8... A rotating shaft 85 is symmetrically rotated on one side of the guide plate 83 at the upper end of 1. A transmission wheel 86 is sleeved on the outer surface of the two rotating shafts 85. The outer surface of the two transmission wheels 86 is sleeved on the same first toothed conveyor belt 87. The first toothed conveyor belt 87 is placed at the middle through hole of one of the baffle plates 84. A driven wheel is fixedly sleeved on the lower end of the transmission wheel 86 on the outer surface of one of the rotating shafts 85. A driving wheel is fixedly sleeved on the outer surface of the output shaft of the conveying motor 72. The driven wheel and the driving wheel are driven by a second toothed conveyor belt 88. Each of the two baffle plates 84 has a groove 89 at one end, and a stop block 810 is slidably arranged in the groove 89. A fixing plate 811 is symmetrically fixed at one end of the guide plate 83. A slot is opened at the upper end of the fixing plate 811, and a top plate 812 is slidably arranged in the slot. Top blocks 813 that are adapted to the top plate 812 are fixedly arranged on both sides of the guide plate 83 at the lower end of the two stops 810. One end of the top plate 812 extends to the outside of the slot and abuts against the top block 813. Reset springs 814 are symmetrically arranged in the slot. The two reset springs 814 are fixedly connected to one end of the top plate 812. A push groove communicating with the slot is opened on one side of the fixing plate 811. Push rods 815 that are adapted to the push groove are symmetrically arranged at both ends of the receiving platform 79. In this embodiment, the conveyor motor 72 drives the driven wheel and the rotating shaft 85 to rotate through the driving wheel and the second toothed conveyor belt 88, causing the first toothed conveyor belt 87 on the transmission wheel 86 to operate. The first toothed conveyor belt 87 drives the bearing on the guide plate 83 to slowly roll downwards, and the baffle plate 84 prevents material leakage. Under normal conditions, the return spring 814 pulls the top plate 812 to retract, and the stop block 810 closes in the slide groove 89 to prevent the bearing from falling. When the receiving platform 79 moves, its push rod 815 inserts into the push groove to push the top plate 812 to open the top block 813, so that the stop block 810 slides open, allowing the bearing to pass through. The path is calculated. When the push rod 815 moves backwards in conjunction with the first half gear 75 and the second half gear 77 and the toothed plate 78, the return spring 814 drives each component to reset, and the stop block 810 moves downwards under the action of gravity, blocking the subsequent bearing and realizing intermittent material conveying.

[0030] For further details, please refer to Figure 1 As shown, a storage box 9 is fixedly installed on the upper end of the base 1 by multiple support rods. The lower end of the storage box 9 has a flat and narrow opening design, and the storage box 9 is placed directly above the higher side of the guide plate 83. The flat and narrow opening design allows the bearing inside to slowly slide down onto the guide plate 83, and then be fed intermittently by the first toothed conveyor belt 87.

[0031] For further details, please refer to Figure 1 , Figure 10 As shown, a feeding plate 10 is fixedly installed at the lower end of both sliding plates 4, and a feeding channel 11 is provided at the lower end of the mounting plate 3. As the sliding plate 4 slides relative to each other, the two unloading plates 10 separate, exposing the unloading channel 11. The polished bearings lose their support and fall into the unloading channel 11. The unloading channel 11 is filled with a sponge pad, which can protect the falling bearings and prevent surface defects. The unloading channel 11 is arc-shaped, and various structures such as a receiving box or conveyor belt can be designed at one end of the channel to further store the polished bearings.

[0032] Example 3: Based on Examples 1 and 2, the working steps of the present invention are as follows: S1, Bearing preparation: The storage box 9 conveys the bearings to the guide plate 83 in an orderly manner through the flat narrow opening. The conveyor motor 72 of the intermittent conveying component 8 drives the first toothed conveyor belt 87 to move and move the bearings. The stop block 810 is normally closed to block the bearings. S2. Precise feeding: In the feeding assembly 7, the conveyor motor 72 drives the first half gear 75 and the second half gear 77 to alternately mesh with the tooth plate 78, driving the receiving platform 79 to move. Its push rod 815 pushes the top plate 812 to open the stop block 810. A single bearing falls into the receiving platform 79 and is sent to the processing station. The stop block 810 is then reset under the action of the return spring 814. S3, Inner ring processing: The rotating motor 53 of the inner ring processing component 5 drives the threaded sleeve 57 to rotate through the bevel gear transmission. The adjusting screw 58 drives the arc block 59 to extend and retract synchronously to adapt to and clamp the inner ring. The first drive motor 51 drives the mounting box 52 to rotate. The first grinding block 512 and the first polishing wheel 513 move with the sliding plate 4 to complete the inner ring processing. S4. Outer ring processing: The arc plate 63 of the outer ring processing component 6 slides and fits to clamp the outer ring, the second drive motor 61 drives the rotating plate 62 to rotate, and the second grinding block 65 and the second polishing wheel 66 synchronously complete the outer ring processing. S5. Material collection: The sliding plate 4 slides relative to the material plate 10 to separate it. The bearing completes the collection through the material channel 11 with sponge pad protection, realizing fully automated operation.
