Description

Technical Field

[0001] This invention relates to the field of bearing ring sorting, specifically to a bearing ring sorting and automatic pairing device. Background Technology

[0002] Bearing races are a key component of a bearing, typically referring to the inner or outer ring, used to support the rolling elements for rotation or to transmit loads. Before final assembly, the bearing races and rolling elements require machining. Because the machining and final assembly of the bearing races involve multiple processes, they need to be transported. In ordinary bearing races, due to their cylindrical structure, the wear generated when two races come into contact during transport does not affect the final production of the bearing. However, when producing... Figure 8 The combined bearing shown includes an inner ring sleeve 35, an outer ring sleeve 33, and a housing ring sleeve 34. One side of the outer ring sleeve has the outer wall structure of a normal needle roller bearing, while the other end face has the raceway structure of a thrust needle roller bearing. When the two outer ring sleeves are arranged in the same direction, the outer wall of one outer ring sleeve will abut against the bearing raceway of the other outer ring sleeve. Collisions and friction during transportation will damage the raceway surface on one end face of the outer ring sleeve, resulting in increased overall friction after bearing installation and severely affecting the overall service life of the bearing. To address the above problems, the invention patent with publication number CN108408373B... This invention provides a fully automatic sorting device for outer ring bushings, which automatically flips outer ring bushings facing the same direction at intervals, placing two outer ring bushings back-to-back or face-to-face. However, it should be noted that because the outer ring bushings are stacked randomly on the device, if two adjacent outer ring bushings were originally placed in opposite directions, the automatic sorting device flips one of the outer ring bushings, causing the two back-to-back outer ring bushings to return to their original sequential arrangement. This can cause wear on the inner wall of the outer ring bushings during transport, increasing the overall friction of the bearing after installation and reducing its overall service life.

[0003] To address this, a bearing ring sorting and automatic pairing device is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a bearing ring sorting and automatic pairing device to solve the problem that during the production of combined bearings, the collision and friction generated when two outer ring bushings are stacked in sequence during the transfer process can damage the inner wall of the outer ring bushings, resulting in increased overall friction after bearing installation and seriously affecting the overall service life of the bearing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A bearing ring sorting and automatic pairing device includes a conveyor belt, a pusher frame on one side of the conveyor belt, an electric pusher rod connected to the pusher frame, the electric pusher rod being fixedly mounted on the support leg of the conveyor belt, a placement rod on one side of the conveyor belt, multiple circular holes on the surface of the conveyor belt, a fixed column placed in each circular hole, a rotating platform rotatably mounted on the fixed column, and an outer ring bearing ring placed on the rotating platform. A switching component is provided on one side of the conveyor belt. The electric pusher rod pushes the pusher frame to one side, pushing the outer ring bearing ring onto the placement rod. A vision detection component is provided on the upper side of the conveyor belt. The vision detection component is connected to the switching component and, while the outer ring bearing ring moves, pushes the switching component to rotate, allowing the next rotating platform to contact the switching component and rotate in the opposite direction. Finally, the electric pusher rod pushes the outer ring bearing ring onto the placement rod.

[0007] When the outer ring bushing sorting and automatic pairing device is in use, the outer ring bushings are conveyed onto the conveyor belt. At this point, the outer ring bushings fall randomly onto the rotating display platform, where they stand upright. After reaching the designated position, the conveyor belt stops, and the electric push rod pushes the outer ring bushings on the rotating display platform onto the placement rod via the push frame. It is important to note that because the two outer ring bushings are positioned facing the same direction, the outer wall of one outer ring bushing abuts against the bearing raceway of the other. Collisions and friction during transport can damage the inner wall of the bearing raceway of the outer ring bushings, increasing the overall friction of the bearing after installation and severely affecting its overall service life. Therefore, when transporting the outer ring bushings, they should be placed back-to-back or facing each other. To prevent the two outer ring bushings from overlapping and causing friction, the electric push rod moves the push frame to one side, moving the outer ring bushing into the placement sleeve rod. This activates the switching component, which in turn rotates the next rotating platform, causing the outer ring bushing on the rotating platform to face the opposite direction to the previous one. The vision inspection component identifies the orientation of the outer ring bushing on the rotating platform, determining if the placement orientation is correct. If the outer ring bushing is not positioned correctly, the switching component is deactivated, ensuring the two outer ring bushings are positioned back-to-back or face-to-face. This prevents collisions and friction during transport from damaging the inner wall of the outer ring bushing, thus ensuring the overall service life of the bearing.

[0008] Preferably, the switching assembly includes a protective plate, hydraulic rods, a connecting pipe, a first compression spring, a first rack, a push wheel, a first gear, a one-way ratchet, a roller, a push column, a limit block, a long rod, a second rack, a connecting block, a second compression spring, and a toothed ring. Protective plates are fixedly installed on both sides of the conveyor belt. Two hydraulic rods are fixedly installed on the protective plates, and a connecting pipe is fixedly installed between the two hydraulic rods. A first compression spring is installed inside each of the two hydraulic rods. One hydraulic rod is located on one side of the conveyor belt, and the other hydraulic rod is fixedly installed at the bottom of the protective plate. A first rack is fixedly installed on each hydraulic rod. A push wheel is rotatably connected to the protective plate. The drive wheel has a first gear fixedly mounted on its shaft. A first rack meshes with the first gear. A one-way ratchet is installed between the drive wheel and the first gear. A roller abuts against the side wall of the drive wheel. A push post is provided on one side of the roller. The roller is rotatably connected to the push post. A limit block is fixedly mounted on the protective plate. A long rod is slidably connected to the limit block. A second rack is fixedly mounted on one end of the long rod. A connecting block is fixedly mounted between the other end of the long rod and the push post. A second compression spring sleeved on the long rod abuts against the rack and the limit block. A gear ring is fixedly mounted on the rotating platform. The gear ring meshes with the second rack.

[0009] When the conveyor belt moves the outer ring bushing on one of the rotating platforms to one side of the electric push rod, the electric push rod moves via a push frame fixed to its movable end, pushing the outer ring bushing on the rotating platform into the placement sleeve rod. After the push frame pushes the outer ring bushing to move, it pushes the swing block on one side of the rotating platform to flip and press against the hydraulic rod below, causing the movable end of the lower hydraulic rod to contract. This, in turn, pushes the liquid in one hydraulic rod to be discharged into the other hydraulic rod through a connecting pipe on one side, causing the movable end of the other hydraulic rod to extend outward. The moving movable end of the hydraulic rod drives the first rack fixed to the movable end of the hydraulic rod to move. The moving first rack pushes the first gear meshing on the first rack to rotate. The first rack drives the first gear to rotate in the forward direction. Because the rotating first gear rotates in the forward direction, it can also drive the push wheel to rotate via a one-way ratchet. The rotating push wheel, when the protrusion on the push wheel... When the rollers come into contact with the rotating platform, the moving rollers push the push column to move. The moving push column drives the connected long rod to move through the connecting block on one side. The moving long rod drives the second rack to mesh with the gear ring, causing the rotating platform to rotate due to the meshing of the second rack and gear ring. When the electric push rod drives the push frame back to its original position, the compressed second compression spring on one side will be released. After the moving end of the hydraulic rod below returns to its original position, it will pull the first rack back to its original position. Because there is a one-way ratchet, the first rack cannot drive the push wheel to rotate when it needs to return to its original position. This prevents the second rack from meshing with the gear ring when the rotating platform moves over next time, ensuring that the rotating platform does not rotate during movement. The two outer ring bushings are set back to back or front to front to avoid collisions and friction during transportation that could damage the inner wall of the outer ring bushings, thus ensuring the overall service life of the bearing.

[0010] Preferably, the number of teeth on the second rack is half the number of teeth on the gear ring, the number of teeth on the first rack is half the number of teeth on the first gear, and the push wheel is provided with a return groove, the arc of the return groove is 180°, and the arc diameter of the return groove is smaller than the radius of the push wheel.

[0011] The number of teeth on the second rack is half the number of teeth on the gear ring. When the rotating platform moves the gear ring and it comes into contact with the second rack on one side, the gear ring will rotate through the fixed second gear. Because the number of teeth on the second rack is half the number of teeth on the gear ring, the gear ring can only rotate 180° each time. This ensures that the axis of the outer ring bushing on the rotating platform is parallel to the axis of the conveyor belt after rotation. This ensures that the two outer ring bushings placed together after each rotation of the rotating platform can be stacked back to back or front to front. The arc of the return groove is 180°, which ensures that the push wheel can always roll from the surface of the push wheel to the return groove during the 180° rotation. This ensures that the second rack can accurately move under the control of the push wheel.

[0012] Preferably, an arc-shaped limiting frame is fixedly installed on the rotating display platform, and swing blocks are provided on both sides of the arc-shaped limiting frame. Multiple mounting blocks are fixedly installed on the rotating display platform, and the swing block is rotatably connected between two mounting blocks. A torsion spring connected to the mounting block is installed on the swing block.

[0013] By setting up an arc-shaped limiting bracket, the outer ring bushing can move more stably with the conveyor belt during placement, preventing it from swaying back and forth on the rotating platform. The arc-shaped limiting bracket also wraps around the outer ring bushing, preventing it from slipping off the platform during conveyor belt movement. The swing blocks mounted on both sides of the arc-shaped limiting bracket further restrict the outer ring bushing, preventing it from falling. The swing blocks, which move the pusher, propel the outer ring bushing away from the center of the two swing blocks and onto the placement rod. Since one of the hydraulic rods is located below the swing block, when there is an outer ring bushing on the rotating platform, the pushed outer ring bushing will push the swing block downwards to press against the hydraulic rod below, ensuring the rotating platform rotates when needed. This arrangement allows the two outer ring bushings to be positioned back-to-back or face-to-face, preventing collisions and friction during transport that could damage the inner wall of the outer ring bushing, thus ensuring the overall lifespan of the bearing.

[0014] Preferably, one section of the protective plate has a rectangular notch, and an arc-shaped protective plate is fixedly installed on the rectangular notch. The arc-shaped protective plate is located on one side of the push wheel, and the second rack is located on the side of the arc-shaped protective plate away from the electric push rod.

[0015] The rectangular notch and the arc-shaped guard plate fixed to the rectangular notch allow the outer ring bushing on the rotating platform to rotate smoothly, preventing the outer ring bushing from hitting the guard plates on both sides during rotation and failing to complete the rotation. At the same time, the second rack is set on the side of the arc-shaped guard plate away from the electric push rod, so that the outer ring bushing will immediately rotate when it moves to the connection between the arc-shaped guard plate and the inner wall of the rectangular notch. This ensures that the rotating platform can rotate when it needs to move. The two outer ring bushings are set back to back or face to face, avoiding collisions and friction during transportation that could damage the inner wall of the outer ring bushing, thereby ensuring the overall service life of the bearing.

[0016] Preferably, the front end of the push frame is harpoon-shaped, the distance between the two fork tips of the push frame is a, the overall width of the swing block is b, and a is greater than b. When the electric push rod pushes the push frame to move, the push frame passes through one of the swing blocks and abuts against the outer ring bushing placed on the arc-shaped limiting frame.

[0017] It is important to note that the front end of the push frame is harpoon-shaped, with the distance between the two fork tips greater than the overall width of the swing block. When an outer ring bushing is placed on the rotating platform, the two fork tips at the front end of the push frame can abut against the outer ring bushing and push it to move. The movement of the outer ring bushing will then abut against the swing block on one side, pushing the swing block downwards to abut against the hydraulic rod below. However, when no outer ring bushing is placed on the rotating platform, the two fork tips at the front end of the push frame cannot abut against the outer ring bushing. Because the width of the middle swing block is smaller than the distance between the two fork tips, the swing block passes through the push frame, preventing the push frame from pushing the swing block downwards and thus preventing it from pressing against the hydraulic rod. This ensures that the switching component can only operate when an outer ring bushing is placed on the rotating platform. The two outer ring bushings are positioned back-to-back or face-to-face to avoid collisions and friction during transport that could damage the inner wall of the outer ring bushing, thereby ensuring the overall service life of the bearing.

[0018] Preferably, two symmetrically arranged arc-shaped magnets are fixedly installed on the fixed column, and two arc-shaped iron plates are sleeved on the outside of the arc-shaped magnets. The arc-shaped iron plates are arranged in cooperation with the arc-shaped magnets, and the arc-shaped iron plates are fixedly installed inside the rotating display stand.

[0019] During the rotation of the conveyor belt, the rotating platform may rotate on its own due to shaking or other reasons, causing the toothed ring and the second rack to come into contact. After the toothed ring continues to move and rotates 180°, the swing block cannot rotate to a position parallel to the conveyor belt. Therefore, it is necessary to ensure that the rotating platform and the swing block on it are always parallel to the conveyor belt during its operation. To achieve this, two symmetrically arranged arc-shaped magnets and two arc-shaped iron plates are used to ensure that the swing block on the rotating platform is always parallel to the conveyor belt. At the same time, this prevents the rotating platform from over-rotating due to the inertia generated when the conveyor belt drives the rotating platform to move quickly. This ensures that after the rotating platform rotates 180°, the outer ring bushings on the rotating platform can be aligned with the placement rod on one side. The two outer ring bushings are set back to back or front to front to avoid collisions and friction during the transfer process, which could damage the inner wall of the outer ring bushings and thus ensure the overall service life of the bearing.

[0020] Preferably, a pneumatic valve is fixedly installed on the protective plate, the pneumatic valve is connected to the connecting pipe, the pneumatic valve is connected to the visual inspection component, and the visual inspection component is located near the swing block on one side.

[0021] It is important to note that when the lifting device pushes the outer ring bushing onto the rotating platform, the front and back sides of the outer ring bushing may face different directions. This means the switching assembly cannot guarantee that the two outer ring bushings will be back-to-back or face-to-face after switching to the next outer ring bushing. Therefore, a visual inspection device is used to detect the outer ring bushings. When it detects that the outer ring bushings are facing different directions, the pneumatic valve opens the connecting pipe, preventing the liquid pumped by one piston rod from entering the hydraulic rod on the other side. This prevents the switching assembly from rotating only one outer ring bushing when the two outer ring bushings are facing each other. The switching assembly can only operate when the outer ring bushings are facing the designated direction, ensuring that the two outer ring bushings are either back-to-back or face-to-face. This prevents collisions and friction during transport that could damage the inner wall of the outer ring bushings, thus ensuring the overall service life of the bearing.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. The electric push rod moves the push frame to one side, moving the outer ring bushing into the placement sleeve rod. At this time, it will drive the switching component to run. The switching component drives the next moving rotating platform to rotate, so that the moving outer ring bushing is in the opposite direction to the previous outer ring bushing. This makes the two outer ring bushings back to back or front to front, avoiding collisions and friction during transportation that could damage the inner wall of the outer ring bushing, thus ensuring the overall service life of the bearing.

[0024] 2. The width of the middle swing block is smaller than the distance between the tips of the push frame forks, so that the swing block cannot squeeze the hydraulic rod. This ensures that the switching component can only be driven when the outer ring bushing is placed on the rotating platform. This prevents the switching component from running even when one of the rotating platforms is empty. It also ensures that the two outer ring bushings can be set back to back or front to front, avoiding damage to the inner wall of the outer ring bushing due to collisions and friction during transportation, thereby ensuring the overall service life of the bearing.

[0025] 3. By using two symmetrically arranged arc-shaped magnets and arc-shaped iron plates, the inertia generated when the conveyor belt drives the rotating platform to move quickly is avoided, which may cause the rotating platform to rotate excessively. This ensures that after the rotating platform rotates 180°, the outer ring bushings on the rotating platform can be aligned with the placement rod on one side. This ensures that the two outer ring bushings can be set back to back or front to front, avoiding collisions and friction during transportation that could damage the inner wall of the outer ring bushings, thereby ensuring the overall service life of the bearing.

[0035] Please see Figures 1 to 8 This invention provides a bearing ring sorting and automatic pairing device, the technical solution of which is as follows:

[0036] Please refer to a bearing ring sorting and automatic pairing device. Figure 1 , Figure 3 , Figure 7 and Figure 8The system includes a conveyor belt 1, a pusher frame 3 on one side of the conveyor belt 1, an electric push rod 2 connected to the pusher frame 3, the electric push rod 2 fixedly installed on the support leg of the conveyor belt 1, a placement sleeve rod 6 on one side of the conveyor belt 1, multiple round holes on the surface of the conveyor belt 1, a fixed column 32 placed in the round hole, a rotating platform 5 rotatably installed on the fixed column 32, an outer ring bushing 33 placed on the rotating platform 5, a visual inspection component 7 on the upper side of the conveyor belt 1, an arc-shaped limit frame 13 fixedly installed on the rotating platform 5, swing blocks 10 on both sides of the arc-shaped limit frame 13, multiple mounting blocks 14 fixedly installed on the rotating platform 5, the swing blocks 10 rotatably connected between two mounting blocks 14, and a torsion spring connected to the mounting blocks 14 installed on the swing blocks 10. The front end of the push frame 3 is shaped like a harpoon. The distance between the two fork tips of the push frame 3 is a, and the overall width of the swing block 10 is b. a is greater than b. When the electric push rod 2 pushes the push frame 3 to move, the push frame 3 passes through one of the swing blocks 10 and abuts against the outer ring bushing 33 placed on the arc-shaped limit frame 13.

[0037] Please see Figure 3 , Figure 4 and Figure 6 Protective plates 4 are fixedly installed on both sides of the conveyor belt 1. Two hydraulic rods 22 are fixedly installed on the protective plates 4, and a connecting pipe 23 is fixedly installed between the two hydraulic rods 22. A first compression spring is installed inside each of the two hydraulic rods 22. One hydraulic rod 22 is located on one side of the conveyor belt 1, and the other hydraulic rod 22 is fixedly installed on the bottom of the protective plate 4. A first rack 30 is fixedly installed on the hydraulic rod 22. A push wheel 27 is rotatably connected to the protective plate 4. A first gear 29 is fixedly installed on the shaft of the push wheel 27. The first rack 30 and the first gear 29 mesh with each other. The push wheel 27 and the first gear... A one-way ratchet is installed between 29. A roller 26 abuts against the side wall of the push wheel 27. A push post 25 is provided on one side of the roller 26. The roller 26 is rotatably connected to the push post 25. A limit block 16 is fixedly installed on the protective plate 4. A long rod 18 is slidably connected to the limit block 16. A second rack 15 is fixedly installed at one end of the long rod 18. A connecting block 17 is fixedly installed between the other end of the long rod 18 and the push post 25. A second compression spring 19 sleeved on the long rod 18 abuts between the rack and the limit block 16. A toothed ring 12 is fixedly installed on the rotating display platform 5. The toothed ring 12 meshes with the second rack 15.

[0038] Please see Figure 3 and Figure 4 The number of teeth on the second rack 15 is half the number of teeth on the gear ring 12, the number of teeth on the first rack 30 is half the number of teeth on the first gear 29, and the push wheel 27 is provided with a return groove 28, the arc of the return groove 28 is 180°, and the arc diameter of the return groove 28 is smaller than the radius of the push wheel 27.

[0039] Please see Figure 1 and Figure 2 One section of the protective plate 4 has a rectangular notch, and an arc-shaped protective plate 11 is fixedly installed on the rectangular notch. The arc-shaped protective plate 11 is located on one side of the push wheel 27, and the second rack 15 is located on the side of the arc-shaped protective plate 11 away from the electric push rod 2.

[0040] Please see Figure 1 , Figure 5 and Figure 6 Two symmetrically arranged arc-shaped magnets 9 are fixedly installed on the fixed column 32. Two arc-shaped iron plates 8 are sleeved on the outside of the arc-shaped magnets 9. The arc-shaped iron plates 8 and the arc-shaped magnets 9 are arranged in a cooperative manner. The arc-shaped iron plates 8 are fixedly installed inside the rotating display platform 5. A pneumatic valve 24 is fixedly installed on the protective plate 4. The pneumatic valve 24 is connected to the connecting pipe 23 and connected to the visual inspection component 7. The visual inspection component 7 is located near the swing block 10 on one side.

[0041] Please see Figure 1 , Figure 6 and Figure 7 When the equipment is running, the outer ring bushing 33 is lifted onto the conveyor belt 1 and transported by the conveyor belt 1. Of course, the outer ring bushing 33 will be lifted onto the rotating platform 5. After being transported to the designated position, the electric push rod 2 pushes the outer ring bushing 33 on the rotating platform 5 into the placement sleeve rod 6 through the push frame 3. At this time, when the outer ring bushing 33 is placed on the rotating platform, the two fork tips at the front end of the push frame 3 can abut against the outer ring bushing 33 and push the outer ring bushing 33 to move. The movement of the outer ring bushing 33 will abut against the swing block 10 on one side and push the swing block 10 to swing downward and abut against the hydraulic rod 22 below.

[0042] Please see Figure 2 , Figure 3 and Figure 4This causes the movable end of the lower hydraulic rod 22 to contract, thereby pushing the liquid in one side of the hydraulic rod 22 to be discharged into the other side of the hydraulic rod 22 through the connecting pipe 23 on one side. This causes the movable end of the other side of the hydraulic rod 22 to extend outward. The moving movable end of the hydraulic rod 22 drives the first rack 30 fixed to the movable end of the hydraulic rod 22 to move. The moving first rack 30 pushes the first gear 29 meshed on the first rack 30 to rotate. The first rack 30 drives the first gear 29 to rotate in the forward direction. Because the rotating first gear 29 rotates in the forward direction, it can also drive the push wheel 27 to rotate through the one-way ratchet. When the protrusion on the rotating push wheel 27 abuts against the roller 26, the moving roller 26 pushes the push column 25 to move. The moving push column 25 is connected to the connecting pipe 23 on one side. The connecting block 17 drives the connected long rod 18 to move. The moving long rod 18 drives the second rack 15 to mesh with the toothed ring 12, so that the moving rotating platform 5 will rotate because the second rack 15 meshes with the toothed ring 12. The number of teeth on the second rack 15 is half the number of teeth on the toothed ring 12. When the rotating platform 5 drives the toothed ring 12 to move and comes into contact with the second rack 15 on one side, it will drive the toothed ring 12 to rotate through the fixed second gear. Since the number of teeth on the second rack 15 is half the number of teeth on the toothed ring 12, the toothed ring 12 can only rotate 180° each time. This ensures that the axis of the outer ring bushing 33 on the rotating platform 5 can be parallel to the axis of the conveyor belt 1 after rotation. This ensures that the two outer ring bushings 33 placed together can be stacked back to back or front to front after each rotation of the rotating platform 5.

[0043] Please see Figure 3 and Figure 4 When the electric push rod 2 drives the push frame 3 back to its original position, the second compression spring 19, which was compressed on one side, will be released. After the movable end of the hydraulic rod 22 below returns to its original position, it will pull the first rack 30 back to its original position. Because there is a one-way ratchet, the first rack 30 cannot drive the push wheel 27 to rotate when it needs to return to its original position. This ensures that the second rack 15 cannot mesh with the gear ring 12 when the rotating platform 5 moves over next time, thus ensuring that the rotating platform 5 will not rotate when it moves.

[0044] Please see Figure 6 and Figure 7 When the outer ring bushing 33 is not placed on the rotating display stand 5, the two fork tips at the front end of the push frame 3 cannot abut against the outer ring bushing 33. The swing block 10 in the middle is smaller than the distance between the two fork tips, so the swing block 10 passes through the push frame 3, making it impossible for the push frame 3 to push the swing block 10 to swing downward, that is, it cannot squeeze the hydraulic rod 22.

[0045] Please see Figure 1 , Figure 4 and Figure 5When the lifting device pushes the outer ring bushing 33 onto the rotating platform 5, the front and back of the outer ring bushing 33 will face different directions. This causes the switching component to be unable to ensure that the two outer ring bushings 33 are in a back-to-back or front-to-front state after switching to the next outer ring bushing 33. Therefore, the visual inspection component 7 inspects the outer ring bushing 33. When it detects that the outer ring bushing 33 is facing different directions, the pneumatic valve 24 can open the connecting pipe 23, preventing the liquid pumped by one piston rod 22 from entering the liquid on the other side. Inside the pressure rod 22, to prevent the two outer ring bushings 33 from being in a relative position, the second rack 15 extends to push one of the outer ring bushings 33 to rotate. Through two symmetrically arranged arc-shaped magnets 9 and two sleeved arc-shaped iron plates 8, the swing block 10 on the rotating platform 5 is always parallel to the conveyor belt 1. At the same time, it avoids the inertia generated when the conveyor belt 1 drives the rotating platform 5 to move quickly, which would cause the rotating platform 5 to rotate excessively. This ensures that after the rotating platform 5 rotates 180°, the outer ring bushings 33 on the rotating platform 5 can be aligned with the placement sleeve 6 on one side.

For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
