Description

Technical Field

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

[0002] Double groove bearings usually refer to rolling bearings designed with two raceways on the inner or outer ring of the bearing. This design allows the bearing to withstand greater radial loads or provide higher rotation accuracy. They are often used in mechanical equipment that requires high load capacity and precise rotation, such as automobiles, industrial machinery, machine tools, and aerospace equipment.

[0003] The assembly of double groove bearings is a key step in the bearing manufacturing process. It involves accurately combining the various components of the bearing to ensure the performance and life of the bearing. Before assembly, the various components of the bearing need to be precisely machined and strictly controlled for quality. These components include the outer ring, inner ring, rolling elements and cage. The bearing assembly must be thoroughly cleaned before assembly to remove any impurities and contaminants that may affect the performance of the bearing. After cleaning, the bearing is usually lubricated with a specific lubricant, which helps to reduce friction, reduce wear and extend the service life of the bearing.

[0004] For example, Chinese patent 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. The bearing assembly system includes a jig transfer mechanism, a jig, an inner ring pushing mechanism, an outer ring feeding mechanism, an inner ring feeding mechanism, a steel ball feeding mechanism, a steel ball separation lubrication injection mechanism, a cage installation mechanism 1, a bearing handling and diversion mechanism, and a bearing turning mechanism. The invention transfers the jig loaded with the bearing between different workstations through the jig transfer mechanism, places it into the jig 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 separation lubrication injection mechanism, installs the cage in the bearing through the cage installation mechanism 1 and the cage installation mechanism 2, and places qualified products and unqualified products in different positions through the detection mechanism and the bearing handling and diversion mechanism. The assembly efficiency of the bearing is improved and the labor cost is saved.

[0006] However, the above device still has some shortcomings in actual use:

[0007] 1. The above device transfers the jig loaded with the bearing between different workstations through the jig transfer mechanism, places it in the jig through the outer ring feeding mechanism and the inner ring feeding mechanism, and places several steel balls between the outer ring and the inner ring through the 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 groove between the inner and outer rings of the bearing, affecting the quality of the bearing and reducing the service life of the bearing in the actual working process.

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

[0009] Therefore, under the above-stated viewpoint, the existing devices still have room for improvement. Summary of the invention

DETAILED DESCRIPTION

[0044] The following is combined with Figure 1-Figure 10 Embodiments of the present invention are described in detail.

[0045] The embodiment of the present application discloses a sleeve assembly device and method for a double-groove bearing, which illustrates that the present invention is mainly used in the process of bearing assembly, and can avoid the problem of lack of accurate and effective installation of bearing rolling elements for double-groove bearings in the prior art in terms of technical effect; further, the present invention can also solve the problem of inability to clean the inside of the bearing in the prior art.

[0046] Embodiment 1:

[0047] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it includes a support frame 1, on which a main shaft 10 is rotatably arranged along its length direction, a working disk 11 is installed on the main shaft 10, and four through circular grooves 12 are equidistantly provided on the working disk 11 along its axis, a conveying member 1 2 for conveying the outer ring of the bearing corresponding to the circular groove 12 is arranged on one side of the working disk 11 on the support frame 1, and a conveying member 2 4 for conveying the inner ring of the bearing corresponding to the circular groove 12 is also arranged on the same side of the working disk 11, and a conveying member 3 5 for adding bearing rolling elements corresponding to the circular groove 12 is arranged on the support frame 1, and the conveying member 1 2, the conveying member 2 4 and the conveying member 3 5 are divided counterclockwise along the axis of the main shaft 10. The outer ring of the bearing is pushed into the circular groove 12 by the conveying member 1 2, and then the circular groove 12 receiving the outer ring of the bearing rotates with the counterclockwise rotation of the working disk 11, corresponding to the conveying member 2 4, and then the inner ring of the bearing is conveyed to the inside of the circular groove 12 by the conveying member 2 4, and the inner ring of the bearing is located inside the outer ring of the bearing, and then the circular groove 12 continues to follow the rotation of the working disk 11 and corresponds to the conveying member 3 5, and the conveying member 3 5 is used to place the bearing rolling body in the gap between the outer ring of the bearing and the inner ring of the bearing, that is, in the corresponding grooves of the outer ring of the bearing and the inner ring of the bearing, to complete the early assembly of the bearing.

[0048] A partition plate 13 corresponding to the circular groove 12 is slidably provided on one side of the working disk 11 close to the conveying member 1 2, and a baffle plate 14 corresponding to the circular groove 12 is rotatably provided on the other side of the working disk 11, and 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 1 2 and the conveying member 2 4 are fixed inside the circular groove 12 by the electromagnet 15, and the partition plate 13 is provided to prevent the rolling element of the bearing from falling during the placement process.

[0049] Reference Figure 3 , Figure 4 and Figure 5 As shown, it is a structural schematic diagram for conveying the outer ring of the bearing; specifically, the conveying member 2 includes an outer ring cylinder 20 coaxially arranged with the circular groove 12, and a connecting pipe 21 connected to the outer ring cylinder 20 is arranged above the outer ring cylinder 20. The outer ring of the bearing enters the outer ring cylinder 20 through the connecting pipe 21, and a sleeve 22 is arranged inside the outer ring cylinder 20. A push ring 23 sleeved on the outside of the sleeve 22 is slidably installed inside the outer ring cylinder 20, and the outer ring of the bearing is pushed into the corresponding circular groove 12 through the push ring 23. An arc-shaped abutment plate 24 is installed on the side of the push ring 23 away from the circular groove 12. When the push ring 23 moves, the abutment plate 24 on the push ring 23 can block the connection between the connecting pipe 21 and the outer ring cylinder 20 to prevent the next bearing outer ring from falling into the outer ring cylinder 20.

[0050] Reference Figure 3 , Figure 4 and Figure 5As shown, it is a schematic diagram of the structure that drives the push ring 23 to slide inside the outer ring tube 20; specifically, a pusher 3 is installed inside the outer ring tube 20, and the pusher 3 includes a sliding shaft 30 that slides through the outer ring tube 20 and the sleeve 22, and a first push plate 31 is installed at one end of the sliding shaft 30 located inside the sleeve 22, and a connecting plate 32 is installed inside the sleeve 22 at a section of the sliding shaft 30 away from the circular groove 12, and the sleeve 22 is penetrated at both ends of the connecting plate 32, and spring telescopic rods 33 are symmetrically arranged on the connecting plate 32, and the telescopic end of the spring telescopic rod 33 is 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 then slide inside the sleeve 22, and the spring telescopic rod 33 on the connecting plate 32 will move with the push ring 23, and the outer ring of the bearing inside the outer ring tube 20 will be pushed into the circular groove 12 through the push ring 23.

[0051] The purpose of setting the spring telescopic rod 33 is that after the push ring 23 pushes the outer ring of the bearing into the circular groove 12, it continues to push the sliding shaft 30 toward the circular groove 12. At this time, the spring telescopic rod 33 contracts, and the sliding shaft 30 continues to approach the outer ring of the bearing with the first push plate 31 in the sleeve 22. The first push plate 31 pushes the air inside the sleeve 22 into the circular groove 12, which can blow away the dust on the outer ring of the bearing, making it convenient to clean the dust on the outer ring of the bearing later. Dust and dirt may cause premature failure or malfunction of the bearing. Cleaning the bearing can reduce this risk and ensure the reliability and stability of the equipment.

[0052] Reference Figure 4 and Figure 7 As shown, it is a schematic diagram of the structure that pushes the inner ring of the bearing into the circular groove 12 corresponding to the outer ring of the bearing; specifically, the conveying member 4 includes a fixed cylinder 40 coaxially arranged with the circular groove 12, an inner ring cylinder 41 is eccentrically arranged inside the fixed cylinder 40, and a connecting pipe 42 is arranged above the inner ring cylinder 41 and is connected to the inner ring cylinder 41 and penetrates the fixed cylinder 40. The inner ring of the bearing enters the inner ring cylinder 41 through the connecting pipe 42, and a push shaft 43 is slidably penetrated on the inner ring cylinder 41 and the fixed cylinder 40. The push shaft 43 has a telescopic structure, and a push plate 44 is installed at one end of the push shaft 43 located inside the inner ring cylinder 41. By driving the push shaft 43 to slide on the inner ring cylinder 41, the push plate 44 is driven to slide in the inner ring cylinder 41 along with the push shaft 43, and the push plate 44 is used to push the inner ring of the bearing into the corresponding circular groove 12 where the outer ring of the bearing has been placed.

[0053] The reason for eccentrically setting the inner ring tube 41 is that when the middle bearing rolling body is placed in the gap between the bearing outer ring and the bearing inner ring, the eccentric setting can make the gap on one side of the bearing outer ring and the bearing inner ring larger, making it more convenient to place the bearing rolling body in the groove, and then pull the bearing inner ring to drive it coaxial with the bearing outer ring, so as to drive the bearing rolling body to slide inside the groove and drive it to be distributed as evenly as possible in the groove.

[0054] Reference Figure 4 , Figure 7 and Figure 8 As shown, it is a schematic diagram of the structure for driving the push plate 44 to slide and clear the gap between the outer ring of the bearing and the inner ring of the bearing; specifically, a push member 6 for driving the push plate 44 to slide inside the inner ring cylinder 41 is installed inside the fixed cylinder 40, and the push member 6 includes a fixed plate 60, and the fixed plate 60 is sleeved on the end of the push shaft 43 located inside the inner ring cylinder 41 away from the circular groove 12, and support rods 61 are symmetrically installed on the fixed plate 60, and a slide plate 62 slidably sleeved on the inner ring cylinder 41 is commonly provided on the telescopic ends of the two support rods 61, wherein the support rod 61 is a spring telescopic structure.

[0055] When the push shaft 43 drives the push plate 44 to move, the fixed plate 60 connected to the push shaft 43 will slide synchronously with the support rod 61 inside the fixed cylinder 40. At this time, the slide plate 62 on the support rod 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 shrinks, and the slide plate 62 slides inside the fixed cylinder 40, pushing the air inside the fixed cylinder 40 into the circular groove 12. 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, preventing the dust from affecting the assembly effect of the bearing and reducing the service life of the subsequent bearing. The blowing method can more effectively blow up the internal dust for collection. Compared with the traditional brush cleaning method, it is easier to take care of the grooves on the outer ring of the bearing and the inner ring of the bearing, and the cleaning is cleaner.

[0056] The fixing cylinder 40 is provided with a mounting groove 63, and a trapezoidal block 64 is slidably arranged inside the mounting groove 63, and a spring is arranged between the trapezoidal block 64 and the mounting groove 63. The elastic force of the spring is greater than the elastic force of the support rod 61, so that before the push plate 44 pushes the inner ring of the bearing into the circular groove 12, the slide plate 62 will not be displaced under the action of the trapezoidal block 64, and the support rod 61 will shrink synchronously. After 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 slide plate 62 to continue to move. The trapezoidal block 64 will shrink into the mounting groove 63 under the action of the slide plate 62. After the slide plate 62 loses the limit of the trapezoidal block 64, it will instantly move toward the circular groove 12 under the elastic force of the support rod 61, increasing the thrust of the slide plate 62 on the air inside the fixing cylinder 40, and improving the cleaning effect on the outer ring of the bearing and the inner ring of the bearing.

[0057] Reference Figure 2 and Fig. 9As shown, it is a schematic diagram of the structure for conveying the bearing rolling elements; specifically, the conveying member 3 5 is a conveying pipe 50, and the conveying pipe 50 is symmetrically arranged on both sides of the working disk 11. The partition 13 and the baffle 14 are provided with a feeding port 51 corresponding to the conveying pipe 50, and a feeding shaft 52 is slidably penetrated at one end of the conveying pipe 50 away from the working disk 11, and a feeding plate 53 is installed at one end of the feeding shaft 52 located in the conveying pipe 50, and a conical block 54 is symmetrically slidably arranged on the side of the conveying pipe 50 close to the working disk 11 through a push spring.

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

[0059] The symmetrically arranged conical blocks 54 will separate from each other when the bearing rolling body approaches the circular groove 12. When the bearing rolling body passes through the two conical blocks 54, the elastic force of the push spring will drive the bearing rolling body through the feed port 51 into the gap between the bearing outer ring and the bearing inner ring.

[0060] Reference Figure 4 and Figure 6 As shown, it is a schematic diagram of the structure of pulling the outer ring of the bearing and the inner ring of the bearing to be concentrically matched; specifically, the working disk 11 and the support frame 1 are jointly provided with a pulling member 7 for pulling the inner ring of the bearing to slide, and the eccentrically arranged inner ring of the bearing can be concentrically matched with the outer ring of the bearing through the pulling member 7, so that the bearing rolling elements in the gap between the outer ring of the bearing and the inner ring of the bearing can be evenly distributed in the groove between the two. The pulling member 7 includes a support block 70, which is arranged on the side of the partition 13 away from the working disk 11, and a driving screw 71 is rotatably mounted on the partition 13, and a driving block 72 is threadedly arranged on the driving screw 71, and a pulling shaft 73 is slidably penetrated through the driving block 72 through a spring, and a through groove for the pulling shaft 73 to slide is provided on the driving screw 71, and a matching groove 74 extending along its length direction is provided on the partition 13, and the pulling shaft 73 is movably matched with the matching 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 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 rolling body of the bearing will move along the groove between the outer ring of the bearing and the inner ring of the bearing until the inner ring of the bearing is placed concentrically with the outer ring of the bearing.

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

[0063] When the driving screw 71 rotates along the main shaft 10 following the partition 13, the gear 80 on the driving screw 71 will cooperate with the rack 82 on the support frame 1 to rotate the driving screw 71. 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 pulling shaft 73 on the driving block 72 will slide on the driving block 72 along the inclined groove of the matching plate 83. Under the influence of the matching plate 83, the pulling shaft 73 approaches the inner ring of the bearing. Therefore, during the rotation of the working disk 11, the circular groove 12 where the outer ring of the bearing, the inner ring of the bearing and the bearing rolling elements are placed will cooperate with the pulling shaft 73, so that the outer ring of the bearing and the inner ring of the bearing are placed coaxially.

[0064] Embodiment 2:

[0065] On the basis of Example 1, in order to further enhance the coordination between the partition 13 and the outer ring tube 20 and the inner ring tube 41, a driving member 9 is also provided. When the outer ring tube 20 and the inner ring tube 41 are needed to convey the bearing outer ring and the bearing inner ring, the partition 13 is driven to move so that the outer ring tube 20 and the inner ring tube 41 can be tightly coordinated with the circular groove 12 on the working disk 11.

[0066] Reference Figure 3 , Figure 4 and Fig.10 As shown, it is a schematic diagram of the structure that drives the partition 13 to cooperate with the outer ring tube 20 and the inner ring tube 41; specifically, a driving member 9 for driving the partition 13 to slide on the working disk 11 is installed on the support frame 1, and the driving member 9 includes a circular plate 90 installed on the support frame 1, and arc blocks 91 are symmetrically installed on the circular plate 90. A driving shaft that passes through the working disk 11 is installed at one end of the partition 13 close to the main shaft 10, and a sliding groove 92 that slides with the driving shaft is opened on the arc block 91.

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

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

[0069] Step 2: The sliding shaft 30 continues to approach the outer ring of the bearing with the first push plate 31 in the sleeve 22. The first push plate 31 pushes the air inside the sleeve 22 into the circular groove 12, which can blow away the dust on the outer ring of the bearing, making it easier to clean the dust on the outer ring of the bearing later.

[0070] Step 3: drive the push shaft 43 to slide on the inner ring tube 41, drive the push plate 44 to slide in the inner ring tube 41 along with 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] Step 4: Drive the push shaft 43 to drive the push plate 44 to move, and the fixed plate 60 connected to the push shaft 43 slides synchronously with the support rod 61 inside 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, the telescopic end of the push shaft 43 shrinks, and the slide plate 62 slides inside the fixed cylinder 40, pushing the air inside the fixed cylinder 40 into the circular groove 12, and blowing up the dust between the outer ring and the inner ring of the bearing.

[0072] Step 5: The bearing rolling body enters into the conveying pipe 50, and the feeding shaft 52 slides in the conveying pipe 50 to drive the feeding plate 53 to push the bearing rolling body into the gap between the bearing outer ring and the bearing inner ring.

[0073] Step 6: The driving block 72 on the driving screw 71 slides 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 body will move along the groove between the outer ring of the bearing and the inner ring of the bearing until the inner ring of the bearing is placed concentrically with the outer ring of the bearing.

[0074] Step 7: After the installation is completed, the partition 13 is turned over, the electromagnet 15 cancels the adsorption of the bearing, and the bearing is collected after it falls.
