Description

Technical Field

[0001] The invention relates to the field of bearing ring material sorting, and in particular to a bearing ring material sorting, sorting and automatic pairing device. Background Art

[0002] The bearing ring is a key component of the bearing, which usually refers to the inner ring or outer ring of the bearing, used to support the rolling element to rotate or transmit loads. Before the final assembly of the bearing, the bearing sleeve and rolling element need to be processed and produced. Because the bearing sleeve requires multiple processes during the processing and final assembly process, the bearing sleeve needs to be transported. During the transportation process of ordinary bearing sleeves, since the bearing sleeves are generally cylindrical in structure, the wear caused by the two bearing sleeves abutting each other will not cause problems for the final production of the bearing; when the production is such as Figure 8 In the case of the combined bearing shown in FIG, the combined bearing includes an inner ring sleeve 35, an outer ring sleeve 33, and a seat ring sleeve 34. One side of the outer ring sleeve is the outer wall structure of a normal needle roller bearing, while the end face of the other side is 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 be against the bearing raceway of the other outer ring sleeve. The collision and friction during the transportation process will cause the raceway surface of one end face of the outer ring sleeve to be damaged, so that the overall friction of the bearing increases after the bearing is installed, seriously affecting the overall service life of the bearing. In response to the above problems, the invention patent with patent publication number CN108408373B The invention provides a fully automatic sorting device for dividing and pairing outer ring sleeves, which automatically flips the outer ring sleeves with the same direction at intervals, so that the two outer ring sleeves can be placed back to back or face to face. Of course, it should be noted that because the outer ring sleeves are stacked on the equipment in disorder, when two adjacent outer ring sleeves are originally placed in two different directions, the automatic sorting device flips one of the outer ring sleeves, causing the two outer ring sleeves placed back to back to be arranged in sequence, causing the inner wall of the outer ring sleeve to wear during the transportation process, which increases the overall friction of the bearing after installation and reduces the overall service life of the bearing.

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

[0004] The purpose of the present invention is to provide a bearing ring sorting and automatic pairing device to solve the problem that when producing combined bearings, the collision and friction generated when the two outer ring sleeves are stacked in sequence during transportation will cause damage to the inner wall of the outer ring sleeve, making the overall friction of the bearing greater after the bearing is installed, seriously affecting the overall service life of the bearing.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A bearing ring material sorting and automatic pairing device comprises a conveyor belt, a pushing frame is provided on one side of the conveyor belt, the pushing frame is connected to an electric push rod, the electric push rod is fixedly installed on the supporting leg of the conveyor belt, a placing sleeve rod is provided on one side of the conveyor belt, a plurality of circular holes are arranged on the belt surface of the conveyor belt, a fixing column is placed in the circular holes, a rotating exhibition stand is rotatably installed on the fixing column, an outer ring shaft sleeve is placed on the rotating exhibition stand, a switching component is provided on one side of the conveyor belt, the electric push rod pushes the pushing frame to one side to push the outer ring shaft sleeve onto the placing sleeve rod, a visual detection part is provided on the upper side of the conveyor belt, the visual detection part is connected to the switching component, and pushes the switching component to operate while the outer ring shaft sleeve moves, so that the next rotating exhibition stand that moves over contacts the switching component and rotates in the opposite direction, and finally the outer ring shaft sleeve is pushed to the placing sleeve rod by the electric push rod.

[0007] When the outer ring sleeve sorting and automatic pairing device is in use, the outer ring sleeve is transported to the conveyor belt. At this time, the outer ring sleeve falls onto the rotating booth in disorder. The outer ring sleeve is upright on the rotating booth. After being transported to the designated position, the conveyor belt stops moving, and the electric push rod pushes the outer ring sleeve on the rotating booth into the placement sleeve rod through the pushing frame. It should be noted that because the two outer ring sleeves are arranged in the same direction, the outer wall of one outer ring sleeve is against the bearing raceway of the other outer ring sleeve. The collision and friction during the transportation process will cause the inner wall of the bearing raceway of the outer ring sleeve to be damaged, making the overall friction of the bearing greater after the bearing is installed, seriously affecting the overall service life of the bearing. Therefore, when the outer ring sleeve is transported, the outer ring sleeves need to be back to back or facing each other. If the outer ring sleeve is placed in an incorrect direction, the switching component is cut off so that the two outer ring sleeves are placed back to back or facing each other, avoiding collision and friction during transportation that may cause damage to the inner wall of the outer ring sleeve, thereby ensuring the overall service life of the bearing.

[0008] Preferably, the switching assembly includes a guard plate, a hydraulic rod, a connecting pipe, a first compression spring, a first rack, a pushing wheel, a first gear, a one-way ratchet, a roller, a pushing column, a limit block, a long rod, a second rack, a connecting block, a second compression spring, and a gear ring. Guard plates are fixedly installed on both sides of the conveyor belt, two hydraulic rods are fixedly installed on the guard plate, a connecting pipe is fixedly installed between the two hydraulic rods, and a first compression spring is installed inside the two hydraulic rods. One of the hydraulic rods is located on one side of the conveyor belt, and the hydraulic rod on the other side is fixedly installed on the bottom of the guard plate. The first rack is fixedly installed on the hydraulic rod, and a pushing wheel is rotatably connected to the guard plate. The driving wheel has a first gear fixedly mounted on the driving wheel shaft, the first rack and the first gear meshing with each other, a one-way ratchet is installed between the driving wheel and the first gear, a roller is abutted on the side wall of the driving wheel, a pushing column is provided on one side of the roller, and the roller is rotatably connected to the pushing column, a limiting block is fixedly mounted on the protective plate, a long rod is slidably connected to the limiting block, one end of the long rod is fixedly mounted with a second rack, and a connecting block is fixedly mounted between the other end of the long rod and the pushing column, a second compression spring sleeved on the long rod abuts between the rack and the limiting block, and a gear ring is fixedly mounted on the rotating booth, and the gear ring and the second rack mesh with each other.

[0009] When the conveyor belt drives the outer ring bushing on one of the rotating booths to move to one side of the electric push rod, the electric push rod moves through the pushing frame fixed at the movable end, pushing the outer ring bushing on the rotating booth onto the placement sleeve rod. After the pushing frame pushes the outer ring bushing to move, it will press against the hydraulic rod below, causing the movable end of the hydraulic rod below to contract, thereby pushing the liquid in the hydraulic rod on one side to be discharged into the hydraulic rod on the other side through the connecting pipe on one side, causing the movable end of the hydraulic rod on the other side to extend outward, and the moving movable end of the hydraulic rod drives the first rack fixed on the movable end of the hydraulic rod to move, and the moving first rack drives the first gear engaged on the first rack to rotate, and the first rack drives the first gear to rotate forward. Because the rotating first gear rotates forward, the first gear can also drive the driving wheel to rotate through the one-way ratchet. When the protrusion on the driving wheel abuts against the roller, The moving roller pushes the pushing column to move, and the moving pushing column drives the connected long rod to move through the connecting block on one side, and the moving long rod drives the second rack to engage with the gear ring, so that the moving rotating exhibition platform will rotate due to the engagement of the second rack with the gear ring. When the electric push rod drives the pushing frame back to its original position, the second compression spring compressed on one side will be released, and after the movable end of the hydraulic rod below returns to its original position, it will pull the first rack back to its original position. Because of the one-way ratchet, the first rack cannot drive the pushing wheel to rotate through the first rack when it needs to return to its original position, so that the second rack cannot engage with the gear ring when the rotating exhibition platform moves next time, ensuring that the rotating exhibition platform will not rotate when it moves, and the two outer ring shaft sleeves are set back to back or facing each other to avoid collision and friction during transportation that may cause damage to the inner wall of the outer ring shaft sleeve, thereby ensuring the overall service life of the bearing.

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

[0011] The number of teeth on the second rack is half of the number of teeth on the gear ring. When the rotating booth drives the gear ring to move and contacts the second rack on one side, the gear ring will be driven to rotate through the fixed second gear. Because the number of teeth on the second rack is half of the number of teeth on the gear ring, the gear ring can only rotate 180° each time, so that the axis of the outer ring bushing on the rotating booth can be parallel to the axis of the conveyor belt after rotation, ensuring that the two outer ring bushings placed together after each rotation of the rotating booth can be stacked back to back or face to face. The arc of the retraction groove is 180°, so that the pushing wheel can always roll from the surface of the pushing wheel to the retraction groove during the 180° rotation, ensuring that the second rack can be accurately displaced under the control of the pushing wheel.

[0012] Preferably, an arc-shaped limit frame is fixedly installed on the rotating display stand, and swing blocks are provided on both sides of the arc-shaped limit frame. A plurality of mounting blocks are fixedly installed on the rotating display stand, 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] The curved limiter ensures that the outer sleeve follows the conveyor more stably during placement, preventing it from rocking back and forth on the rotating platform during conveyor movement. The curved limiter wraps around the outer sleeve, preventing it from sliding off the rotating platform during conveyor movement. Swinging blocks mounted on either side of the curved limiter also restrain the outer sleeve, preventing it from falling. The swinging blocks enable the pusher to move, pushing the outer sleeve away from the center of the two swing blocks and onto the placement rod. Because one of the hydraulic rods is located below the swing block, when the outer sleeve is on the rotating platform, the pushed outer sleeve pushes the swing block downward against the hydraulic rod, ensuring that the rotating platform rotates when required. This allows the two outer sleeves to be positioned back-to-back or aligned, preventing damage to the inner wall of the outer sleeve due to collision and friction during transport, thereby ensuring the overall service life of the bearing.

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

[0015] Through the rectangular notch and the arc-shaped guard plate fixed on the rectangular notch, the outer ring sleeve on the rotating booth can rotate smoothly, avoiding the outer ring sleeve from pressing against the guard plates on both sides during rotation and being unable to complete the rotation. At the same time, the second rack is arranged on the side of the arc-shaped guard plate away from the electric push rod, so that the outer ring sleeve will rotate immediately when it moves to the connection between the arc-shaped guard plate and the inner wall of the rectangular notch, ensuring that the rotating booth can rotate when it needs to rotate during movement, and the two outer ring sleeves are arranged back to back or facing each other to avoid collision and friction during transportation that may cause damage to the inner wall of the outer ring sleeve, thereby ensuring the overall service life of the bearing.

[0016] Preferably, the front end of the pushing frame is harpoon-shaped, the distance between the two fork tips of the pushing 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 pushing frame to move, the pushing frame passes through one of the swing blocks and presses against the outer ring sleeve placed on the arc-shaped limit frame.

[0017] It should be noted that the front end of the pushing frame is harpoon-shaped, and the distance between the two fork tips is greater than the overall width of the swing block. When an outer ring sleeve is placed on the rotating display stand, the two fork tips at the front end of the pushing frame can resist the outer ring sleeve and push the outer ring sleeve to move. The movement of the outer ring sleeve will resist the swing block on one side and push the swing block to swing downward and resist the hydraulic rod below. When there is no outer ring sleeve on the rotating display stand, the two fork tips at the front end of the pushing frame cannot resist the outer ring sleeve, and the middle swing block is smaller than the distance between the two fork tips, so that the swing block passes through the pushing frame, making it impossible for the pushing frame to push the swing block to swing downward, that is, it is impossible to squeeze the hydraulic rod, ensuring that the switching assembly can only be driven to operate when an outer ring sleeve is placed on the rotating display stand, and the two outer ring sleeves are set back to back or facing each other to avoid collision and friction during transportation that may cause damage to the inner wall of the outer ring sleeve, thereby ensuring the overall service life of the bearing.

[0018] Preferably, two symmetrically arranged arc-shaped magnets are fixedly mounted on the fixing column, two arc-shaped iron plates are sleeved on the outer side of the arc-shaped magnets, the arc-shaped iron plates and the arc-shaped magnets are arranged in cooperation with each other, and the arc-shaped iron plates are fixedly mounted in the rotating exhibition stand.

[0019] During the rotation of the transmission belt, the rotating booth may rotate on its own due to shaking and other reasons, causing the gear ring and the second rack to contact each other. After the gear ring continues to move and drives the gear ring to rotate 180°, the swing block cannot rotate to a position parallel to the conveyor belt. Therefore, it is necessary to ensure that the rotating booth and the swing block thereon are always in a parallel state with the conveyor belt during the operation of the conveyor belt. Therefore, two symmetrically arranged arc magnets and two sleeved arc iron plates are used to ensure that the swing block on the rotating booth is always parallel to the conveyor belt. At the same time, the inertia generated when the conveyor belt drives the rotating booth to move rapidly is avoided, which may cause the rotating booth to rotate excessively. Ensure that after the rotating booth rotates 180°, the outer ring sleeves on the rotating booth can be aligned with the placement sleeve rod on one side, so that the two outer ring sleeves are set back to back or facing each other, to avoid collision and friction during transportation that may cause damage to the inner wall of the outer ring sleeve, thereby ensuring the overall service life of the bearing.

[0020] Preferably, a pneumatic valve is fixedly mounted on the protective plate, the pneumatic valve is communicated with the connecting pipe, the pneumatic valve is connected to a visual detection component, and the visual detection component is arranged at a position close to a swing block on one side.

[0021] It should be noted that because the lifting equipment pushes the outer ring sleeve onto the rotating booth, the front and back sides of the outer ring sleeve will face different directions, resulting in the switching component being unable to ensure that after switching the next outer ring sleeve, the front and rear outer ring sleeves are in a back-to-back or face-to-face state. Therefore, the outer ring sleeve is inspected by a visual inspection part. When it is detected that the position of the outer ring sleeve is facing different directions, the pneumatic valve can open the connecting pipe so that the liquid pumped out by the piston rod on one side cannot enter the hydraulic rod on the other side, avoiding that when the two outer ring sleeves are in a relative setting, the switching component still rotates one of the outer ring sleeves, ensuring that the outer ring sleeve faces the set direction before driving the switching component to operate, so that the two outer ring sleeves are set back to back or face to face, avoiding collision and friction during transportation that may cause damage to the inner wall of the outer ring sleeve, thereby ensuring the overall service life of the bearing.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The electric push rod pushes the push frame to one side to move the outer ring sleeve into the placement sleeve rod. At this time, it will drive the switching component to operate, and the switching component drives the next moving rotating booth to rotate, so that the outer ring sleeve that is moved is opposite to the direction of the previous outer ring sleeve, so that the two outer ring sleeves are set back to back or facing each other, avoiding collision and friction during transportation that may cause damage to the inner wall of the outer ring sleeve, thereby ensuring the overall service life of the bearing.

[0024] 2. The width of the middle swing block is smaller than the distance between the fork tips of the push frame, so that the swing block cannot squeeze the hydraulic rod. This ensures that the switching assembly can only be driven when an outer ring sleeve is placed on the rotating booth, and prevents the switching assembly from still running when one of the rotating booths is empty. It ensures that the two outer ring sleeves can be placed back to back or face each other, and avoids collision and friction during transportation that may cause damage to the inner wall of the outer ring sleeve, thereby ensuring the overall service life of the bearing.

[0025] 3. Two symmetrically arranged arc magnets and arc iron plates are used to prevent the rotating platform from excessive rotation due to inertia caused by the rapid movement of the conveyor belt. This ensures that after the rotating platform rotates 180°, the outer ring sleeves on the rotating platform can be aligned with the placement sleeve rod on one side, ensuring that the two outer ring sleeves can be placed back to back or facing each other, avoiding collision and friction during transportation that may cause damage to the inner wall of the outer ring sleeve, thereby ensuring the overall service life of the bearing.

[0037] See also 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 plate 4, a connecting pipe 23 is fixedly installed between the two hydraulic rods 22, and a first compression spring is installed inside 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 at the bottom of the protective plate 4. A first rack 30 is fixedly installed on the hydraulic rod 22, and a driving wheel 27 is rotatably connected to the protective plate 4. A first gear 29 is fixedly installed on the rotating shaft of the driving wheel 27. The first rack 30 and the first gear 29 are meshed with each other, and the driving wheel 27 and the first gear A one-way ratchet is installed between 29, and a roller 26 is abutted on the side wall of the pushing wheel 27. A pushing column 25 is provided on one side of the roller 26, and the roller 26 is rotatably connected to the pushing column 25. A limit block 16 is fixedly installed on the protective plate 4, and a long rod 18 is slidably connected to the limit block 16. A second rack 15 is fixedly installed on one end of the long rod 18, and a connecting block 17 is fixedly installed between the other end of the long rod 18 and the pushing column 25.

[0038] See also Figure 3 and Figure 4 The number of teeth on the second rack 15 is half of the number of teeth on the gear ring 12, the number of teeth on the first rack 30 is half of the number of teeth on the first gear 29, and a return groove 28 is provided on the driving wheel 27. 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 driving wheel 27.

[0039] See also Figure 1 and Figure 2 A rectangular notch is provided in one section of the protective plate 4, on which an arc-shaped protective plate 11 is fixedly mounted. The arc-shaped protective plate 11 is located on one side of the pushing wheel 27, and the second rack 15 is arranged on the side of the arc-shaped protective plate 11 away from the electric push rod 2.

[0040] See also Figure 1 、 Figure 5 and Figure 6 Two symmetrically arranged arc magnets 9 are fixedly mounted on the fixed column 32, and two arc iron plates 8 are sleeved on the outside of the arc magnet 9. The arc iron plates 8 and the arc magnets 9 are arranged in cooperation with each other. The arc iron plates 8 are fixedly mounted in the rotating booth 5, and a pneumatic valve 24 is fixedly mounted on the protective plate 4. The pneumatic valve 24 is connected to the connecting pipe 23, and the pneumatic valve 24 is connected to the visual detection component 7. The visual detection component 7 is arranged near the swing block 10 on one side.

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

[0042] See also Figure 2 、 Figure 3 and Figure 4, causing the movable end of the hydraulic rod 22 below to contract, thereby pushing the liquid in the hydraulic rod 22 on one side to be discharged into the hydraulic rod 22 on the other side through the connecting pipe 23 on one side, causing the movable end of the hydraulic rod 22 on the other side to extend outward, and 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, and the moving first rack 30 drives the first gear 29 meshing on the first rack 30 to rotate, and the first rack 30 drives the first gear 29 to rotate forward. Because the rotating first gear 29 rotates forward, the first gear 29 can also drive the driving wheel 27 to rotate through the one-way ratchet. When the protrusion on the driving wheel 27 abuts against the roller 26, the moving roller 26 drives the driving column 25 to move, and the moving driving column 25 is connected to one side. The connecting block 17 drives the connected long rod 18 to move, and the moving long rod 18 drives the second rack 15 to engage with the gear ring 12, so that the moving rotating exhibition platform 5 will rotate due to the engagement of the second rack 15 with the gear ring 12. The number of teeth on the second rack 15 is half of the number of teeth on the gear ring 12. When the rotating exhibition platform 5 drives the gear ring 12 to move and contacts the second rack 15 on one side, it will drive the gear ring 12 to rotate through the fixed second gear. Because the number of teeth on the second rack 15 is half of the number of teeth on the gear ring 12, the gear ring 12 can only rotate 180° each time it rotates, so that the axis of the outer ring shaft sleeve 33 on the rotating exhibition platform 5 can be parallel to the axis of the conveyor belt 1 after rotation, ensuring that the two outer ring shaft sleeves 33 placed together after each rotation of the rotating exhibition platform 5 can be stacked back to back or face to face.

[0043] See also Figure 3 and Figure 4 When the electric push rod 2 drives the pushing frame 3 to return to its original position, the second compression spring 19 compressed on one side will be released, and 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 of the one-way ratchet, the first rack 30 cannot drive the pushing wheel 27 to rotate when it needs to return to its original position, so that the second rack 15 cannot engage with the gear ring 12 when the rotating display platform 5 moves over next time, ensuring that the rotating display platform 5 does not rotate during movement.

[0044] See also Figure 6 and Figure 7 When the outer ring sleeve 33 is placed on the rotating display rack, the two fork tips at the front end of the pushing rack 3 cannot support the outer ring sleeve 33, and 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 pushing rack 3, making it impossible for the pushing rack 3 to push the swing block 10 to swing downward, that is, it is impossible to squeeze the hydraulic rod 22.

[0045] See also Figure 1 、 Figure 4 and Figure 5When the lifting device pushes the outer ring shaft sleeve 33 onto the rotating exhibition stand 5, the front and back sides of the outer ring shaft sleeve 33 will face different directions, resulting in the switching component being unable to ensure that after the next outer ring shaft sleeve 33 is switched, the front and rear outer ring shaft sleeves 33 are in a back-to-back or front-to-front state. Therefore, the outer ring shaft sleeve 33 is inspected by the visual inspection component 7. When it is detected that the position of the outer ring shaft sleeve 33 is facing different directions, the pneumatic valve 24 can open the connecting pipe 23, so that the liquid pumped out by the piston rod 22 on one side cannot enter the liquid on the other side. The pressure rod 22 prevents the second rack 15 from extending to push one of the outer ring sleeves 33 to rotate when the two outer ring sleeves 33 are in a relative arrangement. The two symmetrically arranged arc magnets 9 and the two sleeved arc iron plates 8 ensure that the swing block 10 on the rotating display platform 5 is always parallel to the conveyor belt 1. At the same time, the inertia generated when the conveyor belt 1 drives the rotating display platform 5 to move rapidly is prevented from causing the rotating display platform 5 to rotate excessively, ensuring that the outer ring sleeves 33 on the rotating display platform 5 can be aligned with the placement sleeve rod 6 on one side after the rotating display platform 5 rotates 180°.
