Abstract
Description
Technical Field
[0001] This invention relates to the field of bearing technology, and in particular to a high-efficiency needle roller device for a needle loading machine. Background Technology
[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Early linear motion bearings consisted of a row of wooden rods placed under a row of skids. Modern linear motion bearings use the same working principle, except that sometimes balls are used instead of rollers. The simplest rotary bearing is the bushing bearing, which is simply a bushing sandwiched between a wheel and an axle.
[0003] In bearing applications, needle rollers are installed on the inner side of the bearing to provide greater load-bearing capacity, lower friction, and higher rigidity. Compared to the larger rolling cylinders or balls, the diameter of the needle rollers is smaller. Therefore, the installation process is usually manual, requiring manual control of the needle rollers as they descend. This operation is slow and results in low needle installation efficiency. In addition, if there are foreign objects between the bearing housing and the needle rollers, jamming may occur during installation, affecting installation efficiency. Furthermore, during installation, the operator needs to support the bearing, which can easily cause shaking.
[0004] To address this issue, we propose a high-efficiency needle roller device for needle loading machines. Summary of the Invention

A first driving gear is fixedly installed on the output end of the first motor. A first driven gear is movably connected to the bottom of the top plate through a rotating shaft. The surface of the first driven gear is connected to the surface of the first driving gear through tooth meshing. A connecting rod is fixedly installed at the bottom of the first driving gear and the first driven gear. A vertical plate is fixedly installed at the bottom of the connecting rod. Multiple needle holes of the same size and equidistant distribution are opened on the top of the box. Multiple limiting sleeves of the same size and equidistant distribution are fixedly installed on the upper and lower sides of the inner cavity of the box. A needle tube is provided on the inner side of the limiting sleeve.
[0009] In a further embodiment, electric push rods are fixedly installed on both the left and right sides of the inner side of the limiting sleeve, and the inner side of the electric push rods is in contact with the surface of the lower needle tube.
[0010] In a further embodiment, the chip removal mechanism includes a second servo motor, a sleeve, and a chip removal box. The second servo motor is fixedly installed on the rear side of the box surface, and the output end of the second servo motor penetrates the surface of the box and extends into the inner cavity of the box. A second driving gear is fixedly installed on the output end of the second servo motor. A second driven gear is movably connected to the left and right sides of the inner cavity of the box via a rotating shaft. The surface of the second driven gear is connected to the surface of the second driving gear by tooth meshing. A toothed plate is fixedly installed on the front side of the second driven gear. The lower needle tube is located in the inner cavity of the sleeve, and multiple through holes are opened on the inner side of the sleeve. The chip removal box is fixedly installed on the front side of the box surface, and connecting blocks are fixedly installed on the upper and lower sides of the rear side of the inner cavity of the box.
[0011] In a further embodiment, a fan is fixedly installed on the front side of the chip removal box surface, and a corrugated pipe is connected to the rear side of the inner cavity of the chip removal box, with the other end of the corrugated pipe connected to the inner cavity of the sleeve.
[0012] In a further embodiment, a toothed rod is movably connected to the inner side of the connecting block, the rear side of the sleeve surface is fixedly installed on the surface of the toothed rod, and the surface of the toothed plate meshes with the surface of the toothed rod through teeth.
[0013] In a further embodiment, the fixing mechanism includes a base, which is fixedly installed on the bottom of the column. Cavities are provided on both the left and right sides of the inner side of the base. A rigid spring is fixedly installed inside the cavity. A partition is fixedly installed at the other end of the rigid spring. A clamping rod is fixedly installed inside the partition. A clamp is fixedly installed inside the clamping rod. A pull plate is fixedly installed outside the clamping rod. A handle is fixedly installed outside the pull plate.
[0014] In a further embodiment, a limiting hole is provided on the inner side of the base, the clamping rod is connected to the clamp through the limiting hole, and an anti-slip sleeve is fixedly installed on the inner side of the clamp.
[0015] In a further embodiment, a locking block is fixedly installed on both the left and right sides of the inner cavity of the chip removal box, and a filter screen is locked inside the locking block.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] Firstly, the needle-dropping mechanism in this invention facilitates efficient needle dropping. After the needle roller is placed on the top of the housing, starting the first motor drives the first drive gear at the output end to rotate. During the rotation of the first drive gear, the first driven gear is driven to rotate through the meshing of the teeth. When the first drive gear and the first driven gear are rotating, they drive the connecting rod to rotate. The rotating connecting rod drives the vertical plate to rotate, thereby moving the needle roller. During the movement, after the needle roller moves above the needle-dropping hole, it is affected by the oblique opening of the needle-dropping hole and automatically falls vertically into the inner cavity of the needle-dropping tube. The operator only needs to align the bottom of the needle-dropping tube with the bearing to install it, thus eliminating the need for manual needle dropping and greatly improving work efficiency.
[0018] Secondly, in this invention, the chip removal mechanism can collect the debris on the surface of the pin header, preventing debris from falling into the bearing after the pin header is processed and affecting installation. In use, the second servo motor can drive the second drive gear at the output end to rotate. While the second drive gear is rotating, it can drive the second driven gear to rotate through the meshing of the teeth. During the rotation of the second driven gear, it can drive the toothed plate on its surface to rotate. During the rotation of the toothed plate, it can drive the rack to move longitudinally back and forth through the meshing of the teeth. While the rack is moving, it can drive the sleeve to move longitudinally back and forth. At this time, the fan can be started. After the fan is started, it can generate suction, thereby collecting the debris on the surface of the roller on the inner side of the lower pin tube to the inner side of the chip removal box through the through hole of the bellows and the inner side of the sleeve.
[0019] Thirdly, in this invention, the bearing can be fixed by the fixing mechanism to prevent the bearing from moving during needle roller installation, which would make installation inconvenient for operators. Pulling the handle outward can move the pull plate outward. As the pull plate moves, it can also move the clamping rod and the partition outward. The movement of the clamping rod can move the clamp outward. During the movement of the partition, the rigid spring can be compressed, causing it to deform. After the bearing is placed between the clamps, the hand can be released from the handle. At this time, the rigid spring, freed from external compression, can rebound through its own tension, thereby moving the partition, clamping rod, and clamp inward, so that the inner side of the clamp contacts the surface of the bearing, thus completing the fixing of the bearing.

Detailed Implementation
[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Please see Figures 1-10 In this embodiment of the invention, a high-efficiency needle roller device for a needle loading machine includes a housing 1. Support rods 2 are fixedly installed on all four sides of the top of the housing 1. A top plate 3 is fixedly installed on the top of the support rods 2. Columns 7 are fixedly installed on all four sides of the bottom of the housing 1. A chip removal mechanism 5 is provided in the inner cavity of the housing 1. A fixing mechanism 6 is provided at the bottom of the column 7.
[0033] A needle-feeding mechanism 4 is provided on the top of the top plate 3. The needle-feeding mechanism 4 includes a first motor 401, which is fixedly installed on the top plate 3. A first driving gear 402 is fixedly installed on the output end of the first motor 401. A first driven gear 403 is movably connected to the bottom of the top plate 3 around the perimeter via a rotating shaft. The surface of the first driven gear 403 is connected to the surface of the first driving gear 402 by tooth meshing. A connecting rod 404 is fixedly installed on the bottom of both the first driving gear 402 and the first driven gear 403. A vertical plate 405 is fixedly installed on the bottom of the connecting rod 404. A plurality of equally spaced and identical needle holes 406 are opened on the top of the box body 1. A plurality of equally spaced and identical limiting sleeves 407 are fixedly installed on the upper and lower sides of the inner cavity of the box body 1. A needle tube 408 is provided on the inner side of the limiting sleeve 407.
[0034] In this invention, the needle-feeding mechanism 4 facilitates efficient needle feeding. After the needle roller is placed on the top of the housing 1, starting the first motor 401 drives the first drive gear 402 at the output end to rotate. During the rotation of the first drive gear 402, the first driven gear 403 is driven to rotate through the meshing of the teeth. When the first drive gear 402 and the first driven gear 403 are rotating, the connecting rod 404 is driven to rotate. The connecting rod 404 rotates simultaneously, driving the vertical plate 405 to rotate, thereby moving the needle roller. During the movement, after the needle roller moves above the needle-feeding hole 406, it is affected by the oblique opening of the needle-feeding hole 406 and automatically falls vertically into the inner cavity of the needle-feeding tube 408. The operator only needs to align the bottom of the needle-feeding tube 408 with the bearing to install it, thus eliminating the need for manual needle feeding and greatly improving work efficiency.
[0035] Specifically, electric push rods 409 are fixedly installed on both the left and right sides of the inner side of the limiting sleeve 407, and the inner side of the electric push rods 409 is in contact with the surface of the lower needle tube 408.
[0036] In this invention, the electric push rod 409 can be used to squeeze the lower needle tube 408, causing its inner cavity to close, thereby limiting the bearing needle roller.
[0037] Specifically, the chip removal mechanism 5 includes a second servo motor 501, a sleeve 506, and a chip removal box 507. The second servo motor 501 is fixedly installed on the rear side of the surface of the box 1, and the output end of the second servo motor 501 passes through the surface of the box 1 and extends into the inner cavity of the box 1. A second driving gear 502 is fixedly installed on the output end of the second servo motor 501. The left and right sides of the inner cavity of the box 1 are movably connected to the second driven gear 503 through a rotating shaft. The surface of the second driven gear 503 is connected to the surface of the second driving gear 502 through tooth meshing. A toothed plate 504 is fixedly installed on the front side of the second driven gear 503. The lower needle tube 408 is located in the inner cavity of the sleeve 506, and multiple through holes are opened on the inner side of the sleeve 506. The chip removal box 507 is fixedly installed on the front side of the surface of the box 1, and connecting blocks 510 are fixedly installed on the upper and lower sides of the rear side of the inner cavity of the box 1.
[0038] In this invention, the chip removal mechanism 5 can collect the chips on the surface of the pin header, preventing chips from falling into the bearing and affecting installation. In use, the second servo motor 501 can drive the second drive gear 502 at the output end to rotate. While the second drive gear 502 is rotating, it can drive the second driven gear 503 to rotate through the meshing of the teeth. During the rotation of the second driven gear 503, it can drive the toothed plate 504 on its surface to rotate. During the rotation of the toothed plate 504, it can drive the rack 505 to move longitudinally reciprocally through the meshing of the teeth. While the rack 505 is moving, it can drive the sleeve 506 to move longitudinally reciprocally.
[0039] Specifically, a fan 508 is fixedly installed on the front side of the chip removal box 507, and a bellows 509 is connected to the rear side of the inner cavity of the chip removal box 507. The other end of the bellows 509 is connected to the inner cavity of the sleeve 506.
[0040] In this invention, suction is generated when the fan 508 is started, thereby collecting the debris on the surface of the roller needle inside the lower needle tube 408 through the through hole on the inner side of the corrugated pipe 509 and the sleeve 506.
[0041] Specifically, the inner side of the connecting block 510 is movably connected to the toothed rod 505, the rear side of the sleeve 506 is fixedly installed on the surface of the toothed rod 505, and the surface of the toothed plate 504 meshes with the surface of the toothed rod 505 through teeth.
[0042] In this invention, the connecting block 510 is connected to the rack 505, which can limit the rack 505 and improve the stability of the rack 505 during movement.
[0043] Specifically, the fixing mechanism 6 includes a base 601, which is fixedly installed at the bottom of the column 7. Cavities 602 are provided on both the left and right sides of the inner side of the base 601. A rigid spring 603 is fixedly installed inside the cavity 602. A partition 604 is fixedly installed at the other end of the rigid spring 603. A clamping rod 605 is fixedly installed inside the partition 604. A clamp 606 is fixedly installed inside the clamping rod 605. A pull plate 607 is fixedly installed outside the clamping rod 605. A handle 608 is fixedly installed outside the pull plate 607.
[0044] In this invention, the fixing mechanism 6 can fix the bearing, preventing it from moving during needle roller installation and making installation inconvenient for operators. Pulling the handle 608 outward can move the pull plate 607 outward. As the pull plate 607 moves, it can also move the clamping rod 605 and the partition 604 outward. The movement of the clamping rod 605 can move the clamp 606 outward. During the movement of the partition 604, the rigid spring 603 can be compressed, causing it to deform. After the bearing is placed between the clamps 606, the hand can release the handle 608. The rigid spring 603, freed from external compression, can rebound due to its own tension, thereby moving the partition 604, clamping rod 605, and clamp 606 inward. This brings the inner side of the clamp 606 into contact with the surface of the bearing, thus fixing the bearing.
[0045] Specifically, a limiting hole 610 is provided on the inner side of the base 601, and the clamping rod 605 is connected to the clamp 606 through the limiting hole 610. An anti-slip sleeve 609 is fixedly installed on the inner side of the clamp 606.
[0046] In this invention, the clamping rod 605 can be limited by the limiting hole 610, and the anti-slip sleeve 609 can prevent the bearing from sliding during the fixing period.
[0047] Specifically, the chip removal box 507 has locking blocks 8 fixedly installed on both the left and right sides of its inner cavity, and a filter screen 9 is locked inside the locking blocks 8.
[0048] In this invention, the filter screen 9 can be fixed by the setting of the card block 8, and the filter screen 9 can block the waste debris absorbed by the fan 508.
[0049] The working principle of this invention is as follows: By pulling the handle 608 outward, the pull plate 607 can be moved outward. Simultaneously, the pull plate 607 moves the clamping rod 605 and the partition 604 outward. The movement of the clamping rod 605 moves the clamp 606 outward. During the movement of the partition 604, the rigid spring 603 is compressed, causing it to deform. After the bearing is placed between the clamps 606, the hand can release the handle 608. At this point, the rigid spring 603, freed from external compression, can release its own tension. The springback action causes the partition 604, clamping rod 605, and clamp 606 to move inward, bringing the inner side of clamp 606 into contact with the bearing surface, thus securing the bearing. After the needle roller is placed on top of the housing 1, starting the first motor 401 drives the first drive gear 402 at the output end to rotate. During rotation, the first drive gear 402 drives the first driven gear 403 to rotate through tooth meshing. Furthermore, during the rotation of the first drive gear 402 and the first driven gear 403, the connecting rod 404 can be driven to rotate. The connecting rod 404 rotates, causing the vertical plate 405 to rotate as well, which in turn moves the needle roller. During this movement, once the needle roller reaches above the lower needle hole 406, it is affected by the angled opening of the lower needle hole 406 and automatically falls vertically into the inner cavity of the lower needle tube 408. The operator only needs to align the bottom of the lower needle tube 408 with the bearing for installation. After the second servo motor 501 is started, it drives the second drive gear 502 at the output end to rotate. Simultaneously, the second drive gear 502 rotates, and the teeth meshing... The second driven gear 503 is rotated, and during the rotation of the second driven gear 503, the toothed plate 504 on its surface is rotated. During the rotation of the toothed plate 504, the tooth meshing action drives the rack 505 to move longitudinally back and forth. At the same time, the rack 505 drives the sleeve 506 to move longitudinally back and forth. At this time, the fan 508 can be started. After the fan 508 is started, it generates suction, thereby collecting the debris on the surface of the roller on the inner side of the lower needle tube 408 through the through hole on the inner side of the bellows 509 and the sleeve 506 to the inner side of the chip removal box 507.
[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
