Description

Technical Field

[0001] The present invention relates to the technical field of bearing assembly, and particularly to a sleeve assembling device and method for a double-groove bearing. Background Art

[0002] A double-groove bearing generally refers to a rolling bearing with two raceways designed on the inner ring or outer ring of the bearing. This design allows the bearing to withstand greater radial loads or provide higher rotational precision, and they are commonly used in mechanical equipment that requires high load-bearing capacity and precise rotation, such as automobiles, industrial machinery, machine tools, and aerospace equipment, etc.

[0003] The assembly of a double-groove bearing is a key link in the bearing manufacturing process, which involves precisely combining the various components of the bearing to ensure the performance and lifespan of the bearing. Before assembly, precise machining and strict quality control are required for each component of the bearing. These components include the outer ring, inner ring, rolling elements, and cage. The bearing components must be thoroughly cleaned before assembly to remove any impurities and contaminants that may affect the bearing performance. After cleaning, the bearing is usually lubricated with a specific lubricant, which helps reduce friction, reduce wear, and extend the service life of the bearing.

[0004] For example, the Chinese patent with the publication number CN118088586B discloses a fully automatic bearing assembly system.

[0005] It relates to the field of bearing assembly equipment, especially a fully automatic bearing assembly system. This bearing assembly system includes a fixture transfer mechanism, a fixture, an inner ring pushing mechanism, an outer ring feeding mechanism, an inner ring feeding mechanism, a steel ball feeding mechanism, a steel ball separating lubricating and oil injecting mechanism, a cage installation mechanism I, a bearing handling and diverting mechanism, and a bearing flipping mechanism. This invention transfers the fixture loaded with the bearing between different workstations through the fixture transfer mechanism, places it into the fixture through the outer ring feeding mechanism and the inner ring feeding mechanism, places several steel balls between the outer ring and the inner ring through the steel ball feeding mechanism, separates several steel balls through the steel ball separating lubricating and oil injecting mechanism, installs the cage in the bearing respectively through the cage installation mechanism I and the cage installation mechanism II, and places the qualified products and unqualified products at different positions respectively through the detection mechanism and the bearing handling and diverting mechanism. It improves the assembly efficiency of the bearing and saves labor costs.

[0006] However, there are still some deficiencies in the above device during actual use:

[0007] 1. The above-mentioned device transfers the fixture loaded with bearings between different stations through a fixture transfer mechanism, places them into the fixture through an outer ring feeding mechanism and an inner ring feeding mechanism, and places several steel balls between the outer ring and the inner ring through a steel ball feeding mechanism to achieve the installation of the bearing. However, during the installation process, there is a lack of a cleaning mechanism for the inner and outer rings of the bearing, which will cause dust to remain in the grooves between the inner and outer rings of the bearing, affecting the quality of the bearing and reducing its service life during actual operation.

[0008] 2. The above-mentioned device places several steel balls between the outer ring and the inner ring through a steel ball feeding mechanism. However, the above-mentioned device can only be used for bearings with a single groove and cannot install steel balls for double-groove bearings, resulting in low applicability.

[0009] Therefore, under the viewpoints stated above, there is still room for improvement in the existing device. Summary of the Invention

[0010] In order to solve the above problems, the present invention provides a sleeve assembling device and method for double-groove bearings.

[0014] Preferably, a first driving member is installed inside the outer cylinder. The first driving member includes a sliding shaft that slidably passes through the outer cylinder and the sleeve. One end of the sliding shaft located inside the sleeve is provided with a first pushing plate. A connecting plate is installed inside the sleeve at a section of the sliding shaft away from the circular groove. Both ends of the connecting plate pass through the sleeve. Spring telescopic rods are symmetrically arranged on the connecting plate, and the telescopic ends of the spring telescopic rods are connected to the pushing ring.

[0015] Preferably, the second conveying member includes a fixed cylinder coaxially arranged with the circular groove. An inner cylinder is eccentrically arranged inside the fixed cylinder. Above the inner cylinder, there is a second connecting pipe that is communicated with the inside of the inner cylinder and passes through the fixed cylinder. A pushing shaft slidably passes through the inner cylinder and the fixed cylinder. One end of the pushing shaft located inside the inner cylinder is provided with a pushing plate.

[0016] Preferably, a second driving member for driving the pushing plate to slide inside the inner cylinder is installed inside the fixed cylinder. The second driving member includes a fixing plate sleeved on the end of the pushing shaft located inside the inner cylinder and away from the circular groove. Support rods are symmetrically installed on the fixing plate. A sliding plate that slidably sleeves on the inner cylinder is jointly arranged on the telescopic ends of the two support rods.

[0017] Preferably, an installation groove is opened inside the fixed cylinder. A trapezoidal block is slidably arranged inside the installation groove. A spring is arranged between the trapezoidal block and the installation groove.

[0018] Preferably, the third conveying member includes a conveying pipe symmetrically arranged on both sides of the working disk. Feeding ports corresponding to the conveying pipe are opened on both the partition plate and the baffle plate. A feeding shaft slidably passes through the end of the conveying pipe away from the working disk. A feeding plate is installed at one end of the feeding shaft located inside the conveying pipe. Conical blocks are symmetrically and slidably arranged on one side of the conveying pipe close to the working disk through pushing springs.

[0019] Preferably, a pulling member for pulling the inner ring of the bearing to slide is jointly arranged on the working disk and the support frame. The pulling member includes a support block arranged on the side of the partition plate away from the working disk. A driving screw rod is rotatably installed on the partition plate. A driving block is threadedly arranged on the driving screw rod. A pulling shaft slidably passes through the driving block through a spring. A through groove for the pulling shaft to slide is opened on the driving screw rod. A matching groove extending along its length direction is opened on the partition plate. The pulling shaft is movably matched with the matching groove.

[0020] Preferably, a gear is arranged at one end of the driving screw rod close to the main shaft. A fixed ring sleeved outside the main shaft is installed on the support frame. A rack matched with the gear is installed on the fixed ring. A matching plate movably matched with the upper end of the pulling shaft is also installed on the fixed ring. An inclined groove is opened on one side of the matching plate.

[0021] On the other hand, a method for assembling a double-groove bearing is as follows:

[0022] S1. Outer ring placement: The sliding shaft slides on the sleeve, the connecting plate slides inside the sleeve, and the spring telescopic rod on the connecting plate drives the push ring to move, pushing the bearing outer ring inside the outer ring cylinder into the circular groove;

[0023] S2. Outer ring cleaning: The sliding shaft drives the first push plate inside the sleeve to continue approaching the bearing outer ring. The first push plate pushes the air inside the sleeve into the circular groove, blowing up the dust on the bearing outer ring for cleaning;

[0024] S3. Inner ring placement: The push shaft slides on the inner ring cylinder, driving the push plate to slide inside the inner ring cylinder along with the push shaft, and pushing the bearing inner ring into the corresponding circular groove where the bearing outer ring has been placed;

[0025] S4. Inner ring cleaning: The push shaft drives the push plate to move. The fixing plate connected to the push shaft drives the support rod to slide synchronously inside the fixed cylinder. After the push plate pushes the bearing inner ring into the circular groove, the push shaft continues to slide, the telescopic end of the push shaft contracts, and the sliding plate slides inside the fixed cylinder, pushing the air inside the fixed cylinder into the circular groove to blow up the dust between the bearing outer ring and the bearing inner ring;

[0026] S5. Ball placement: The bearing rolling elements enter the delivery pipe. The feeding shaft slides inside the delivery pipe to drive the feeding plate to push the bearing rolling elements into the gap between the bearing outer ring and the bearing inner ring;

[0027] S6. Concentric setting: The driving block on the driving screw slides along the length direction of the driving screw. At this time, the pull shaft on the driving block will pull the bearing inner ring to slide inside the bearing outer ring until the bearing inner ring and the bearing outer ring are concentrically placed;

[0028] S7. Bearing collection: After the installation is completed, the partition flips, the electromagnet cancels the adsorption of the bearing, and the bearing is collected after it falls off.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] First, by setting the conveyor 1, the conveying member 2, and the conveying member 3, the bearing outer ring, the bearing inner ring, and the bearing rolling elements are sequentially placed in the circular groove of the working plate, and the bearing rolling elements are conveyed from both sides of the bearing by the conveying member 3. It can not only adapt to ordinary bearings but also target double-groove bearings, ensuring that the bearing rolling elements in the two grooves of the double-groove bearing can be placed in equal amounts.

[0031] Second, by providing the first pusher and the second pusher, when placing the outer bearing ring and the inner bearing ring into the corresponding circular grooves, the outer bearing ring and the inner bearing ring in the circular grooves can also be cleaned by blowing air during the pushing process, preventing dust in the bearing from affecting the quality of the bearing and improving the qualified rate of bearing installation.

Detailed implementation manners

[0044] The following will be combined with the attached Figures 1 - 10 to describe the embodiments of the present invention in detail.

[0045] The embodiments of the present application disclose a sleeve assembling device and method for double-groove bearings. It should be noted that the present invention is mainly applied in the process of bearing assembly. In terms of technical effects, it can avoid the problem in the prior art that there is a lack of accurate and effective installation of bearing rolling elements for double-groove bearings; further, the present invention can also solve the problem in the prior art that the inside of the bearing cannot be cleaned.

[0046] Embodiment 1:

[0047] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, it includes a support frame 1. A main shaft 10 is rotatably arranged on the support frame 1 along its length direction. A working disk 11 is installed on the main shaft 10. Four through circular grooves 12 are equidistantly arranged on the working disk 11 along its axis. On one side of the working disk 11 on the support frame 1, there is a conveying member 2 for the outer ring of the bearing corresponding to the circular groove 12. On the same side of the working disk 11, there is also a conveying member 4 for the inner ring of the bearing corresponding to the circular groove 12. On the support frame 1, there is a conveying member 5 for adding bearing rolling elements corresponding to the circular groove 12. The conveying member 2, the conveying member 4, and the conveying member 5 are distributed counterclockwise along the axis of the main shaft 10 and are all movably matched with the circular groove 12. The outer ring of the bearing is pushed into the circular groove 12 by the conveying member 2. Then, the circular groove 12 containing the outer ring of the bearing rotates with the counterclockwise rotation of the working disk 11 and corresponds to the conveying member 4. Next, the inner ring of the bearing is conveyed into the circular groove 12 by the conveying member 4, and the inner ring of the bearing is located inside the outer ring of the bearing. Then, the circular groove 12 continues to rotate with the working disk 11 and corresponds to the conveying member 5. The bearing rolling elements are placed in the gap between the outer ring and the inner ring of the bearing, that is, in the corresponding grooves of the outer ring and the inner ring of the bearing, to complete the preliminary assembly of the bearing.

[0048] On one side of the working disk 11 close to the conveying member 2, a partition plate 13 corresponding to the circular groove 12 is slidably arranged. On the other side of the working disk 11, a baffle plate 14 corresponding to the circular groove 12 is rotatably arranged. An electromagnet 15 is installed on the side of the baffle plate 14 close to the working disk 11. The outer ring and the inner ring of the bearing conveyed by the conveying member 2 and the conveying member 4 are fixed inside the circular groove 12 by the electromagnet 15. By setting the partition plate 13, it is prevented that the bearing rolling elements fall during the placement process.

[0049] Refer to Figure 3 、 Figure 4 and Figure 5 As shown in the figure, it is a schematic structural diagram for conveying the outer ring of the bearing. Specifically, the conveying member 2 includes an outer cylinder 20 coaxially arranged with the circular groove 12. Above the outer cylinder 20, there is a connecting pipe 21 communicating with the outer cylinder 20. The outer ring of the bearing enters the outer cylinder 20 through the connecting pipe 21. Inside the outer cylinder 20, there is a sleeve 22. A push ring 23 sleeved outside the sleeve 22 is slidably installed inside the outer cylinder 20. The outer ring of the bearing is pushed into the corresponding circular groove 12 by the push ring 23. An arc-shaped abutting plate 24 is installed on the side of the push ring 23 far from the circular groove 12. When the push ring 23 moves, the abutting plate 24 on the push ring 23 can block the connection between the connecting pipe 21 and the outer cylinder 20 to prevent the next outer ring of the bearing from falling into the outer cylinder 20.

[0050] Refer to Figure 3 、 Figure 4 and Figure 5As shown, it is a schematic structural diagram of the structure that drives the push ring 23 to slide inside the outer cylinder 20. Specifically, a first pusher 3 is installed inside the outer cylinder 20. The first pusher 3 includes a sliding shaft 30 that slidably penetrates the outer cylinder 20 and the sleeve 22. A first push plate 31 is installed at one end of the sliding shaft 30 located inside the sleeve 22. A connecting plate 32 is installed inside the sleeve 22 at a section of the sliding shaft 30 far from the circular groove 12. Both ends of the connecting plate 32 penetrate the sleeve 22. Spring telescopic rods 33 are symmetrically arranged on the connecting plate 32, and the telescopic ends of the spring telescopic rods 33 are connected to the push ring 23. By pushing the sliding shaft 30 to slide on the sleeve 22, the connecting plate 32 connected to the sliding shaft 30 will slide inside the sleeve 22, and the spring telescopic rods 33 on the connecting plate 32 will drive the push ring 23 to move. The outer ring of the bearing inside the outer cylinder 20 is pushed into the circular groove 12 through the push ring 23.

[0051] The function of setting the spring telescopic rods 33 is that after the push ring 23 pushes the outer ring of the bearing into the circular groove 12, continue to push the sliding shaft 30 closer to the circular groove 12. At this time, the spring telescopic rods 33 contract, and the sliding shaft 30 drives the first push plate 31 inside the sleeve 22 to continue approaching the outer ring of the bearing. The first push plate 31 pushes the air inside the sleeve 22 into the circular groove 12, which can blow up the dust on the outer ring of the bearing, facilitating the subsequent cleaning of the dust on the outer ring of the bearing. Dust and dirt may cause the bearing to fail prematurely or malfunction. Cleaning the bearing can reduce this risk and ensure the reliability and stability of the equipment.

[0052] Refer to Figure 4 and Figure 7 As shown, it is a schematic structural diagram of pushing the inner ring of the bearing into the circular groove 12 to correspond to the outer ring of the bearing. Specifically, the second conveyor 4 includes a fixed cylinder 40 coaxially arranged with the circular groove 12. An inner cylinder 41 is eccentrically arranged inside the fixed cylinder 40. Above the inner cylinder 41, there is a second connecting pipe 42 that is connected to the inside of the inner cylinder 41 and penetrates the fixed cylinder 40. The inner ring of the bearing enters the inner cylinder 41 through the second connecting pipe 42. A push shaft 43 is slidably penetrated through the inner cylinder 41 and the fixed cylinder 40. The push shaft 43 has a telescopic structure. A push plate 44 is installed at one end of the push shaft 43 located inside the inner cylinder 41. By driving the push shaft 43 to slide on the inner cylinder 41, the push plate 44 is driven to slide inside the inner cylinder 41 along with the push shaft 43, and the inner ring of the bearing is pushed into the corresponding circular groove 12 where the outer ring of the bearing has been placed by using the push plate 44.

[0053] The reason for the eccentric setting of the inner cylinder 41 is that when placing the rolling elements of the bearing in the gap between the outer ring and the inner ring of the bearing, the eccentric setting can make the gap on one side of the outer ring and the inner ring of the bearing larger, making it more convenient to place the rolling elements of the bearing in the grooves. Subsequently, pulling the inner ring of the bearing to make it coaxial with the outer ring can drive the rolling elements of the bearing to slide inside the grooves and drive them to be as evenly distributed in the grooves as possible.

[0054] Refer to Figure 4 、 Figure 7 and Figure 8 As shown, it is a schematic structural diagram of driving the sliding of the push plate 44 and cleaning the gap between the outer ring of the bearing and the inner ring of the bearing; specifically, a second driving member 6 for driving the push plate 44 to slide inside the inner ring cylinder 41 is installed inside the fixed cylinder 40. The second driving member 6 includes a fixing plate 60. The fixing plate 60 is sleeved on one end of the push shaft 43 located inside the inner ring cylinder 41 and far from the circular groove 12. Symmetrically installed on the fixing plate 60 are support rods 61. A sliding sleeve 62 that slides inside the inner ring cylinder 41 is jointly provided on the telescopic ends of the two support rods 61. Among them, the support rod 61 is a spring telescopic structure.

[0055] When the push shaft 43 drives the push plate 44 to move, the fixing plate 60 connected to the push shaft 43 will drive the support rods 61 to slide synchronously inside the fixed cylinder 40. At this time, the sliding plate 62 on the support rods 61 will slide along the fixed cylinder 40. When the push plate 44 pushes the inner ring of the bearing into the circular groove 12, the push shaft 43 continues to slide. At this time, the telescopic end of the push shaft 43 contracts, and the sliding plate 62 slides inside the fixed cylinder 40, pushing the air inside the fixed cylinder 40 into the circular groove 12. And the gap between the fixed cylinder 40 and the inner ring cylinder 41 corresponds to the gap between the outer ring of the bearing and the inner ring of the bearing, which can blow up the dust between the outer ring of the bearing and the inner ring of the bearing, prevent the dust from affecting the assembly effect of the bearing, reduce the service life of the subsequent bearing, and the dust inside can be blown up and collected more effectively by the blowing method. Compared with the traditional brush cleaning method, it is easier to take care of the grooves on the outer ring and the inner ring of the bearing, and the cleaning is cleaner.

[0056] An installation groove 63 is opened inside the fixed cylinder 40. A trapezoidal block 64 is slidably arranged inside the installation groove 63. A spring is arranged between the trapezoidal block 64 and the installation groove 63. The elastic force of the spring is greater than the elastic force of the support rod 61. Thus, before the push plate 44 pushes the inner ring of the bearing into the circular groove 12, the sliding plate 62 will not displace under the action of the trapezoidal block 64, and the support rod 61 will contract synchronously. When the push plate 44 pushes the inner ring of the bearing into the circular groove 12, the push shaft 43 continues to move, which will drive the sliding plate 62 to continue to move. The trapezoidal block 64 will contract into the installation groove 63 under the action of the sliding plate 62. After the sliding plate 62 loses the limit of the trapezoidal block 64, it will instantaneously move towards the circular groove 12 under the elastic force of the support rod 61, increasing the thrust of the sliding plate 62 on the air inside the fixed cylinder 40 and improving the cleaning effect on the inside of the outer ring and the inner ring of the bearing.

[0057] Refer to Figure 2 and Figure 9As shown, it is a schematic structural diagram of conveying the bearing rolling elements; specifically, the conveying member III 5 is a conveying pipe 50, and the conveying pipes 50 are symmetrically arranged on both sides of the working disk 11. Feeding ports 51 corresponding to the conveying pipes 50 are provided on both the partition plate 13 and the baffle plate 14. A feeding shaft 52 is slidably inserted through one end of the conveying pipe 50 away from the working disk 11. A feeding plate 53 is installed at one end of the feeding shaft 52 located inside the conveying pipe 50. On the side of the conveying pipe 50 close to the working disk 11, tapered blocks 54 are symmetrically and slidably arranged through push springs.

[0058] The bearing rolling elements enter the conveying pipe 50, and the feeding shaft 52 slides inside the conveying pipe 50 to drive the feeding plate 53 to push the bearing rolling elements into the gap between the bearing outer ring and the bearing inner ring.

[0059] The symmetrically arranged tapered blocks 54 will separate from each other during the process of the bearing rolling elements approaching the circular groove 12. After the bearing rolling elements pass through the two tapered blocks 54, the elastic force of the push spring will drive the bearing rolling elements to enter the gap between the bearing outer ring and the bearing inner ring through the feeding port 51.

[0060] Refer to Figure 4 and Figure 6 As shown, it is a schematic structural diagram of pulling the bearing outer ring and the bearing inner ring into concentric fit; specifically, a pulling member 7 for pulling the bearing inner ring to slide is jointly arranged on the working disk 11 and the support frame 1. Through the pulling member 7, the eccentrically arranged bearing inner ring can be concentrically fitted with the bearing outer ring, so that the bearing rolling elements in the gap between the bearing outer ring and the bearing inner ring can be evenly distributed in the grooves between the two. The pulling member 7 includes a support block 70. The support block 70 is arranged on the side of the partition plate 13 away from the working disk 11. A driving screw 71 is rotatably installed on the partition plate 13. A driving block 72 is threadedly arranged on the driving screw 71. A pull shaft 73 is slidably inserted through the driving block 72 through a spring. A through groove for the pull shaft 73 to slide is provided on the driving screw 71. A fitting groove 74 extending along its length direction is provided on the partition plate 13. The pull shaft 73 is movably fitted with the fitting groove 74.

[0061] When the driving screw 71 rotates, the driving block 72 on the driving screw 71 will slide along the length direction of the driving screw 71. At this time, the pull shaft 73 on the driving block 72 will pull the bearing inner ring to slide inside the bearing outer ring. During the pulling process, the bearing rolling elements will move along the grooves between the bearing outer ring and the bearing inner ring until the bearing inner ring and the bearing outer ring are concentrically placed.

[0062] Refer to Figure 4 and Figure 6As shown, it is a schematic structural diagram of the structure that drives the draw shaft 73 to cooperate with the inner ring of the bearing. Specifically, a gear 80 is provided at one end of the driving screw 71 close to the main shaft 10. A fixing ring 81 sleeved outside the main shaft 10 is installed on the support frame 1. A rack 82 that cooperates with the gear 80 is installed on the fixing ring 81. A mating plate 83 that movably cooperates with the upper end of the draw shaft 73 is also installed on the fixing ring 81. An inclined groove is formed on one side of the mating plate 83.

[0063] When the driving screw 71 rotates along with the partition plate 13 around the main shaft 10, the gear 80 on the driving screw 71 will cooperate with the rack 82 on the support frame 1, causing the driving screw 71 to rotate. At the same time, the driving block 72 on the driving screw 71 will move synchronously with the driving screw 71. At this time, the draw shaft 73 on the driving block 72 will slide on the driving block 72 along the inclined groove of the mating plate 83. Driven by the mating plate 83, the draw shaft 73 approaches the inside of the inner ring of the bearing. Thus, during the rotation of the working disk 11, the circular groove 12 containing the outer ring of the bearing, the inner ring of the bearing, and the bearing rolling elements will cooperate with the draw shaft 73, enabling the outer ring and the inner ring of the bearing to be coaxially placed.

[0064] Embodiment 2:

[0065] On the basis of Embodiment 1, in order to further enhance the cooperation between the partition plate 13 and the outer cylinder 20 and the inner cylinder 41, a driving member 9 is also provided. When it is necessary to use the outer cylinder 20 and the inner cylinder 41 to convey the outer ring and the inner ring of the bearing, the partition plate 13 is driven to move, so that the outer cylinder 20 and the inner cylinder 41 can be closely fitted with the circular groove 12 on the working disk 11.

[0066] Refer to Figure 3 、 Figure 4 and Figure 10 As shown, it is a schematic structural diagram of the structure that drives the partition plate 13 to cooperate with the outer cylinder 20 and the inner cylinder 41. Specifically, a driving member 9 for driving the partition plate 13 to slide on the working disk 11 is installed on the support frame 1. The driving member 9 includes a circular plate 90 installed on the support frame 1. Arc-shaped blocks 91 are symmetrically installed on the circular plate 90. One end of the partition plate 13 close to the main shaft 10 is provided with a driving shaft passing through the working disk 11. A sliding groove 92 for slidingly cooperating with the driving shaft is formed on the arc-shaped block 91.

[0067] When the working disk 11 is rotating, when installing the inner ring and the outer ring of the bearing, it is necessary to drive the partition plate 13 away from the circular groove 12 corresponding to the outer cylinder 20 and the inner cylinder 41 to facilitate the approach of the outer cylinder 20 and the inner cylinder 41 to the circular groove 12 for feeding. After installing the inner cylinder 41, it is necessary to drive the partition plate 13 to move towards the position of the circular groove 12 to block the circular groove 12 and prevent the bearing rolling elements from falling during the installation of the bearing.

[0068] During operation: First step, by pushing the sliding shaft 30 to slide on the sleeve 22, driving the connecting plate 32 to slide inside the sleeve 22, the spring telescopic rod 33 on the connecting plate 32 will drive the pushing ring 23 to move, and the outer ring of the bearing inside the outer sleeve 20 is pushed into the circular groove 12 through the pushing ring 23.

[0069] Second step: The sliding shaft 30 drives the first pushing plate 31 inside the sleeve 22 to continue approaching the outer ring of the bearing. The first pushing plate 31 pushes the air inside the sleeve 22 into the circular groove 12, which can blow up the dust on the outer ring of the bearing, facilitating the subsequent cleaning of the dust on the outer ring of the bearing.

[0070] Third step: Drive the push shaft 43 to slide on the inner sleeve 41, drive the push plate 44 to slide inside the inner sleeve 41 following the push shaft 43, and use the push plate 44 to push the inner ring of the bearing into the corresponding circular groove 12 where the outer ring of the bearing has been placed.

[0071] Fourth step: Drive the push shaft 43 to drive the push plate 44 to move. The fixing plate 60 connected to the push shaft 43 drives the support rod 61 to slide synchronously inside the fixed cylinder 40. After the push plate 44 pushes the inner ring of the bearing into the circular groove 12, the push shaft 43 continues to slide, the telescopic end of the push shaft 43 contracts, and the sliding plate 62 slides inside the fixed cylinder 40, pushing the air inside the fixed cylinder 40 into the circular groove 12 to blow up the dust between the outer ring and the inner ring of the bearing.

[0072] Fifth step: The bearing rolling elements enter the conveying pipe 50. The feeding shaft 52 slides inside the conveying pipe 50 to drive the feeding plate 53 to push the bearing rolling elements into the gap between the outer ring and the inner ring of the bearing.

[0073] Sixth step: Drive the driving block 72 on the driving screw 71 to slide along the length direction of the driving screw 71. At this time, the pulling shaft 73 on the driving block 72 will pull the inner ring of the bearing to slide inside the outer ring of the bearing. During the pulling process, the bearing rolling elements will move along the grooves between the outer ring and the inner ring of the bearing until the inner ring and the outer ring of the bearing are concentrically placed.

[0074] Seventh step: After the installation is completed, the partition plate 13 flips, the electromagnet 15 cancels the adsorption of the bearing, and the bearing is collected after falling.
