Thin-walled bearings are widely used in aviation, automobiles, electronic equipment and other fields. During the production and use of bearings, dust covers are usually installed on both sides of the bearings to prevent dust, moisture and other foreign matter from entering the bearings, maintain lubrication inside the bearings and improve operational safety.
[0003] Referring to the Chinese patent document with announcement number CN110142591B, entitled A bearing double-sided capping machine and its capping method, in this patent, when it is necessary to press the dust cover onto the bearing, first the sliding assembly drives the clamping assembly to the loading station, the staff places the bearing on the lower positioning clamping block, the upper positioning clamping block moves down and cooperates with the lower positioning clamping block to clamp and position the bearing, then the sliding assembly drives the clamped bearing to move to the pressing station, the transverse motors on both sides of the bearing drive the guide sleeve to move toward the middle, and at the same time the discharge cylinder installed above the guide sleeve pushes the dust cover to be pressed into the guide sleeve from top to bottom, and then the two pressing cylinders are pushed out synchronously, respectively pushing the dust covers to be pressed in the two guide sleeves, the dust covers to be pressed are pressed into the channels on both sides of the bearing, and the dust covers are pressed.
[0004] Referring to the above technical solution, when the bearing is placed on the clamping block, the bearing tends to deviate to one side. Therefore, when the pressing cylinder pushes the dust cover into the bearing, there is a risk that one side of the dust cover is not completely pressed into the bearing, reducing the installation effect of the dust cover. Summary of the invention
[0005] In order to improve the technical problems that the dust cover is not pressed into the bearing during the press-fitting process and the installation effect of the dust cover is poor, the present application provides an automatic pressing device and a pressing process for the dust cover of a thin-walled bearing.

[0007] By adopting the above technical solution, when a thin-walled bearing needs to be installed, the conveying mechanism conveys the bearing, and the bearing passes through the pressure plate and is conveyed to the first station and the second station in sequence; the bearing entering between the pressure plate and the workbench will be pressed by the pressure plate under the action of the restoring force of the first return spring, and can continue to move under the conveyance of the conveying mechanism. The pressure plate and the first return spring can keep the position of the bearing stable in the vertical direction, making it convenient to install the end cover on the bearing.
[0008] After the bearing moves to the first and second stations, the positioning block moves toward the workbench, and the movement of the positioning block drives the push block to move. The push block corresponding to the first station is blocked by the pressure plate, and the push plate corresponding to the second station is blocked by the workbench. Then the positioning block continues to move, and the push block moves into the second sliding groove. The movement of the push block compresses the second return spring and moves the top block away from the second sliding groove. The movement of the top block pushes the dust cover to move, and the center axis of the dust cover coincides with the center axis of the positioning block.
[0009] After the dust cover of the thin-walled bearing is installed, the positioning block moves away from the workbench, and the push block moves away from the second sliding groove relative to the positioning block under the action of the second return spring. The movement of the push block drives the top block to move toward the second sliding groove.

At the same time, the top block can push the dust cover so that the central axis of the dust cover coincides with the central axis of the positioning block, so that the dust cover can be automatically aligned with the groove of the bearing, reducing the difficulty of positioning and installing the dust cover and the bearing, and facilitating the installation of the dust cover. In the present application, the dust covers at both ends of the bearing are respectively installed at the first station and the second station and can be carried out simultaneously, reducing the trouble of manual loading and manual turning over of the bearing, which is conducive to saving manpower and ensuring work efficiency.
[0011] Optionally, the diameter of the first sliding groove is greater than the diameter of the dust cover, and the diameter of the first sliding groove opened corresponding to the second workstation gradually decreases from top to bottom.
[0012] By adopting the above technical solution, the setting of the first sliding groove can reduce the risk of the dust cover being unable to pass through, and the setting of the first sliding groove corresponding to the second station with a gradually reduced diameter can guide the falling of the dust cover.
[0013] Optionally, a loading mechanism is provided on the workbench, which is used to push the lower dust cover and the upper dust cover into the first station and the second station respectively; the loading mechanism includes silos arranged below and above the workbench corresponding to the first station and the second station, and push plates are provided in the silos, and the push plates and the bottom wall of the silo are connected by a third return spring. A discharge port is provided at one end of the silo close to the workbench, and first linear drives are installed on both sides of the workbench corresponding to the first station and the second station, and the first linear drive can push the dust cover in the silo.

The dust cover entering the first station falls on the positioning block, and the dust cover entering the second station falls above the bearing through the first sliding groove.
[0015] Optionally, a guide groove is provided at one end of the top block located at the second workstation away from the second sliding groove, and a moving block is arranged in the guide groove. The moving block and the top wall of the guide groove are connected by a fourth return spring, wherein when the push block starts to move into the second sliding groove, the bottom height of the moving block is the same as the upper end height of the bearing.
[0016] By adopting the above technical solution, when the push block starts to move into the second sliding groove, the moving block can move driven by the top block and can move upwards blocked by the bearing, thereby reducing the risk of interference between the moving block and the bearing.
[0017] Through the setting of the moving block and the fourth return spring, on the one hand, the pushing range of the upper dust cover can be increased, which facilitates the upper dust cover to be pushed and aligned with the center of the positioning block, which is beneficial to improving the installation effect. On the other hand, it can reduce the interference between the moving block and the bearing, which is beneficial to ensure the life of the moving block.

[0047] When the bearing needs to be transported, the conveyor belt 31 first transports the bearing to the workbench 2, and then the telescopic end of the second linear drive 32 extends to drive the moving plate to move. The movement of the moving plate pushes the bearing to move the length of a bearing diameter, and the movement of the bearing pushes the adjacent bearing to move.
[0048] Reference Figure 2 The feeding mechanism 4 includes a bin 41, a push plate 42, a third return spring 43 and a first linear actuator 45. The bin 41 is a hollow cylinder with an open end and an axis extending up and down. There are two bins 41, which are respectively arranged at the lower side and the upper side of the workbench 2 corresponding to the first station 11 and the second station 12, and the open end of the bin 41 faces the workbench 2. The end of the bin 41 close to the workbench 2 is provided with a discharge port 44 (refer to Figure 8 ).

[0050] When the dust cover needs to be loaded, the telescopic end of the first linear actuator 45 moves to drive the sliding plate to move, and the sliding plate moves to push the dust cover to the first station 11 and the second station 12.
[0051] Reference Figures 2 to 5The positioning mechanism 5 includes a pressing plate 51, a first return spring, a positioning block 52, a first sliding groove 53, a push block 54, a second sliding groove 521, a second return spring 55, a top block 56 and a third sliding groove 522. The pressing plate 51 is horizontally arranged above the workbench 2 and can cover the first station 11 and the second station 12. The lower side wall of the pressing plate 51 close to the second linear actuator 32 is inclined. The inclined arrangement of the pressing plate 51 facilitates the bearing to enter between the workbench 2 and the pressing plate 51, thereby reducing the risk of the bearing being unable to move on the workbench 2.
[0052] The first return spring is arranged between the pressure plate 51 and the workbench 2. The arrangement of the first return spring can cooperate with the pressure plate 51 to press the bearing, thereby facilitating the vertical positioning of the bearing and facilitating the installation of the end cover on the bearing.
[0053] Reference Figure 2 and Figure 3 There are two positioning blocks 52, and the two positioning blocks 52 are respectively arranged below and above the workbench 2 corresponding to the first workstation 11 and the second workstation 12. The ends of the two positioning blocks 52 close to the workbench 2 are both frustum-shaped. The two positioning blocks 52 can move up and down relative to each other. Through the conical setting of the positioning blocks 52, the positioning blocks 52 can adjust the bearing position during the movement process, so that the center axis of the bearing coincides with the center axis of the positioning blocks 52.
[0054] Reference Figure 2 and Figure 4 There are two first sliding grooves 53, which are respectively opened at the workbench 2 facing the first station 11 and the pressure plate 51 facing the second station 12. The maximum diameter of the positioning block 52 can pass through the first sliding groove 53. The diameter of the first sliding groove 53 is larger than the outer diameter of the dust cover and smaller than the outer diameter of the bearing. The diameter of the first sliding groove 53 corresponding to the second station 12 gradually decreases from top to bottom. The setting of the first sliding groove 53 can reduce the risk of the dust cover being unable to pass through, and the setting of the first sliding groove 53 corresponding to the second station 12 with a gradually decreasing diameter can guide the falling of the dust cover.
[0055] Reference Figure 3 , the same number of push blocks 54 are provided corresponding to the positioning blocks 52, each push block 54 is provided at one end of a positioning block 52 close to the workbench 2, the second sliding groove 521 is opened in the positioning block 52, the push block 54 can move up and down along the second sliding groove 521, the second return spring 55 is arranged between the positioning block 52 and the second sliding groove 521, a plurality of top blocks 56 are provided, and the plurality of top blocks 56 are respectively arranged on the side walls of the positioning block 52, the third sliding groove 522 is opened on the positioning block 52 and can allow the top block 56 to move horizontally, and the second sliding groove 521 is connected to the third sliding groove 522.
[0056] Reference Figure 4 and Figure 5 When the second return spring 55 is not compressed, the distance between the end of the top block 56 away from the second sliding groove 521 and the center of the positioning block 52 is equal to the radius of the inner hole of the bearing. Before the push block 54 has not completely entered the second sliding groove 521, the top block 56 moves to the farthest position and is limited. At this time, the distance between the end of the top block 56 away from the second sliding groove 521 and the center of the positioning block 52 is equal to the radius of the inner hole of the dust cover. The farthest position of the top block 56 can be limited by providing a retaining ring on the positioning block 52 directly opposite the top block 56, and the inner wall diameter of the retaining ring is equal to the inner diameter of the dust cover.
[0057] When the positioning block 52 moves toward the direction approaching the workbench 2, the positioning block 52 drives the push block 54 to move. The push block 54 set corresponding to the first station 11 is blocked by the pressure plate 51, and the push plate 42 set corresponding to the second station 12 is blocked by the workbench 2. Then the positioning block 52 continues to move, and the push block 54 moves into the second sliding groove 521. The movement of the push block 54 compresses the second return spring 55 and moves the top block 56 away from the second sliding groove 521. The movement of the top block 56 pushes the dust cover to move, and the central axis of the dust cover coincides with the central axis of the positioning block 52.
[0058] After completing the installation of the dust cover of the thin-walled bearing, the positioning block 52 moves away from the workbench 2, and the push block 54 moves away from the second sliding groove 521 under the action of the second return spring 55. The movement of the push block 54 drives the top block 56 to move relative to the positioning block 52 toward the second sliding groove 521.
[0059] Reference Figure 3 , Figure 6 and Figure 7 The press-fitting mechanism 7 includes a first air groove 562, a second air groove 523, an annular block 71, a fourth sliding groove 524, a fifth return spring 72 and a pressing block 73. The first air groove 562 is provided on the top block 56 and is connected to the second sliding groove 521. The second air groove 523 is provided on the positioning block 52. The annular block 71 is provided on the positioning block 52. The inner hole of the annular block 71 is greater than or equal to the inner hole of the dust cover. The outer diameter of the annular block 71 is less than or equal to the outer diameter of the dust cover. The annular block 71 is used to push the dust cover. The fourth sliding groove 524 is provided on the positioning block 52 and can allow the annular block 71 to move up and down. The fourth sliding groove 524 is connected to the second air groove 523. When the top block 56 moves to an end away from the second sliding groove 521, the second air groove 523 is connected to the first air groove 562.
[0060] When the top block 56 moves to the end away from the second sliding groove 521, the second air groove 523 is connected to the first air groove 562, and then the positioning block 52 continues to move, the top block 56 stops moving, the push block 54 is blocked from continuing to move into the second sliding groove 521, and the annular block 71 moves in the direction away from the fourth sliding groove 524.
[0061] Reference Figure 6 and Figure 7 The pressing block 73 is arranged at one end of the annular block 71 away from the fourth sliding groove 524, and the fifth return spring 72 is arranged between the pressing block 73 and the annular block 71; when the annular block 71 moves, the movement of the annular block 71 drives the pressing block 73 to move, and the movement of the pressing block 73 pushes the dust cover to move and compresses the fifth return spring 72, and then the positioning block 52 is aligned with the center of the bearing and presses the bearing, and the pressing block 73 presses the dust cover into the bearing under the action of the restoring force of the fifth return spring 72.
[0062] By setting the pressing mechanism 7, when the positioning block 52 is moved to adjust the position of the bearing, the dust cover aligned with the center of the positioning block 52 can be moved down synchronously, and when the dust cover is aligned with the bearing, the dust cover can automatically enter the bearing, saving operation time and improving production efficiency. The structure is simple and no additional power source is required, which is beneficial to saving energy. By setting the pressing block 73 and the fifth return spring 72, a buffering effect can be played on the process of pressing the dust cover into the bearing, reducing the risk of damage to the dust cover, which is beneficial to improving the installation effect of the dust cover.
[0063] Reference Figure 6 and Figure 8 , an automatic dust cover pressing device for a thin-walled bearing further comprises a guide groove 561, a moving block 6 and a fourth return spring 61. The guide groove 561 is provided at one end of the top block 56 located at the second station 12 away from the second sliding groove 521, and the height of the top block 56 located in the second station 12 is greater than the height of the top block 56 located in the first station 11, the moving block 6 is slidably arranged in the second sliding groove 521, and the fourth return spring 61 is arranged between the bottom wall of the second sliding groove 521 and the moving block 6.
[0064] When the push block 54 starts to move into the second sliding groove 521 , the moving block 6 can move driven by the top block 56 and can move upwards blocked by the bearing, thereby reducing the risk of interference between the moving block 6 and the bearing.
[0065] Through the setting of the moving block 6 and the fourth return spring 61, on the one hand, the pushing range of the upper dust cover can be increased, which facilitates the upper dust cover to be pushed and aligned with the center of the positioning block 52, which is beneficial to improving the installation effect. On the other hand, it can reduce the interference between the moving block 6 and the bearing, which is beneficial to ensure the life of the moving block 6.
[0066] In the present application, by placing the bearing on the workbench 2 and arranging the pressure plate 51 and the first return spring, the position of the bearing can be limited, which facilitates the installation of the dust cover and reduces the risk of poor installation of the dust cover due to the uncertain position of the bearing. By arranging the positioning block 52, the push block 54 and the top block 56, the positioning block 52 can adjust the position of the bearing during movement. At the same time, the top block 56 can push the dust cover so that the central axis of the dust cover coincides with the central axis of the positioning block 52, so that the dust cover can be automatically aligned with the groove of the bearing, reducing the difficulty of positioning and installing the dust cover and the bearing, and facilitating the installation of the dust cover. In the present application, the dust covers at both ends of the bearing are installed at the first station 11 and the second station 12 respectively and can be carried out simultaneously, reducing the trouble of manual loading and manual turning over of the bearing, which is conducive to saving manpower and ensuring work efficiency.
[0067] The implementation principle of the automatic press-fitting device for the dust cover of a thin-walled bearing in the embodiment of the present application is as follows:
[0068] When the dust cover needs to be installed on the bearing, the conveyor belt 31 first receives the bearing and conveys the bearing to the workbench 2, then the telescopic end of the second linear actuator 32 extends to push the bearing on the workbench 2, the bearing that has not been pressed into the cover enters under the pressure plate 51, and the bearing located at the first station 11 enters the second station 12, then the telescopic ends of the two first linear actuators 45 extend and push the dust cover to move, the lower dust cover located under the workbench 2 enters the first station 11 and falls on the positioning block 52, and the upper dust cover located above the workbench 2 passes through the first sliding groove 53 and falls on the bearing located at the second station 12.
[0069] After completing the loading of the dust cover, the positioning block 52 moves toward the direction close to the workbench 2, and the movement of the positioning block 52 drives the push block 54 to move. The push block 54 corresponding to the first station 11 is blocked by the pressure plate 51, and the push plate 42 corresponding to the second station 12 is blocked by the workbench 2. Then the positioning block 52 continues to move, and the push block 54 moves into the second sliding groove 521. The movement of the push block 54 compresses the second return spring 55, and causes the top block 56 and the moving block 6 to move away from the second sliding groove 521. At the same time, the moving block 6 is blocked by the bearing and moves upward during the movement, causing the fourth return spring 61 to be compressed. The top block 56 and the moving block 6 move to push the dust cover to move, and then the top block 56 moves to the end away from the second sliding groove 521 and stops moving. The center axis of the dust cover coincides with the center axis of the positioning block 52.
[0070] When the top block 56 moves to one end away from the second sliding groove 521, the second sliding groove 521 is connected to the fourth sliding groove 524 through the first air groove 562 and the second air groove 523, and then the positioning block 52 continues to move, and the push block 54 continues to slide into the second sliding groove 521. The annular block 71 moves in a direction away from the fourth sliding groove 524 and drives the pressure block 73 to move. The pressure block 73 moves to push the dust cover to move and compress the fifth return spring 72. Then the positioning block 52 is aligned with the center of the bearing and presses the bearing. Under the action of the restoring force of the fifth return spring 72, the pressure block 73 pushes the dust cover to be pressed into the bearing. The bearing located at the first station 11 completes the installation of the lower dust cover, and the bearing located at the second station 12 completes the pressing of the upper dust cover.
[0071] After the dust cover is pressed and installed, the positioning block 52 moves in the direction away from the workbench 2, and the push block 54 moves in the direction away from the second sliding groove 521 relative to the positioning block 52 under the action of the second return spring 55. The annular block 71 and the pressing block 73 move into the fourth sliding groove 524. Then the first air groove 562 and the second air groove 523 are separated, and the positioning block 52 continues to move in the direction away from the workbench 2. The push block 54 continues to move in the direction away from the second sliding groove 521 relative to the positioning block 52 under the action of the second return spring 55. The top block 56 and the moving block 6 move in the direction close to the second sliding groove 521. At the same time, the distance between the moving block 6 and the bottom wall of the guide groove 561 gradually increases under the action of the restoring force of the fifth return spring 72. Then the push block 54 stops moving relative to the positioning block 52, the positioning block 52 moves and synchronously drives the push block 54 to move, and the positioning block 52 and the push block 54 move out of the first sliding groove 53.
[0072] After the positioning block 52 moves out of the first sliding groove 53, the conveyor belt 31 continues to convey the bearing, and the second linear drive 32 continues to push the bearing. The bearing located on the side of the first station 11 away from the second station 12 enters between the pressure plate 51 and the workbench 2, and the bearing on which the lower dust cover is installed at the first station 11 is pushed to the second station 12, and the bearing on which the upper dust cover is installed at the second station 12 is pushed out of the second station 12, and then the above operation is repeated to continue to push the lower dust cover and the upper dust cover to the first station 11 and the second station 12 for installation.

[0074] S1, loading, the second linear actuator 32 pushes the bearing into the first station 11 and the second station 12, and the first linear actuator 45 pushes the lower dust cover and the upper dust cover into the first station 11 and the second station 12 respectively;
[0075] S2, alignment, first the positioning block 52 moves, the push block 54 is blocked and moves into the second sliding groove 521, the second return spring 55 is compressed, the top block 56 moves away from the second sliding groove 521, and at the same time the moving block 6 is blocked by the bearing and moves upward, so that the fourth return spring 61 is compressed, and then the top block 56 stops moving, the dust cover coincides with the central axis of the positioning block 52, and the third sliding groove 522 is connected with the fourth sliding groove 524;
[0076] S3, press-fitting, the positioning block 52 continues to move and enables the push block 54 to continue to move into the second sliding groove 521, the pressing block 73 moves and pushes the dust cover to move, then the positioning block 52 presses the bearing, the bearing is positioned, the positioning block 52 stops moving, and the dust cover is pressed into the bearing under the action of the pressing block 73 and the fifth return spring 72.
[0077] By adopting the above-mentioned technical method, when the positioning block 52 moves to adjust the position of the bearing, the dust cover can be adjusted to be concentric with the positioning block 52, and can automatically enter the bearing when aligned with the bearing, and the first station 11 and the second station 12 can be carried out at the same time, and the lower dust cover and the upper dust cover of the bearing can be installed respectively, which saves operation time and is conducive to improving production efficiency. In addition, the whole process does not require manual loading and turning of the end cover, saving manpower.
