Description
Technical Field
[0001] This utility model belongs to the field of cross roller bearing manufacturing technology, and more specifically, it relates to an assembly device for cross roller bearings used in robots. Background Technology
[0002] Crossed roller bearings are core components of industrial robot joints, and their assembly precision directly affects the robot's motion accuracy and reliability. These bearings consist of an outer ring, an inner ring, a cage, and cylindrical rollers arranged at 90° angles. The assembly process requires precise control of the roller crossing angle, cage positioning accuracy, and bearing clearance.
[0003] During the assembly of cross roller bearings, operators need to use precision tweezers to pass through the pre-set installation window of the outer ring raceway and insert the rollers one by one into the designated slots of the cage isolation grid. Since key processes such as roller orthogonal angle calibration, cage alignment and clearance adjustment rely entirely on manual visual operation and experience judgment, it is difficult to improve the assembly cycle. Furthermore, fluctuations in operation can easily lead to problems such as roller misalignment or uneven contact stress, which seriously restricts the mass production efficiency of high-precision bearings.

[0012] Furthermore, the top material assembly includes a top material rod, which is movably connected to a guide tube.

[0016] This utility model has the following beneficial effects:
[0017] This invention uses a clamping assembly and a pressing drive assembly to fix the inner and outer rings of the bearing. At the same time, the outer feeding device can move the roller to the bottom of the top material assembly through a rotating guide assembly and a transfer assembly. This allows the top material assembly to push the roller into the slot on the cage through the installation window. Each time a roller is installed, the rotating guide assembly rotates 90°. Meanwhile, the pressing drive assembly drives the cage to rotate at a moving angle through the inner ring of the bearing.

The whole process does not require manual intervention, thus improving the accuracy and efficiency of roller installation.
[0018] This invention uses an electric push rod, a drive plate, and a connecting bar to drive the top material rod to the lower side of the push tube. The drive plate and two wedge blocks on the connecting frame then cooperate to push the connecting frame, which in turn pushes the terminal into the transfer box via the pull rod and the push tube. When the top material rod moves to the upper side of the push tube again, the limit rod releases its limit on the pull rod. At this time, the connecting frame, under the elastic force of the return spring, pushes the push tube and the terminal into the guide tube again via the pull rod. The above configuration allows the terminal at the upper end of the top material rod to move normally to the lower end, thus ensuring that the guide tube can discharge material normally while the top material rod can push material normally.

[0034] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0035] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0036] Please see Figures 1-7 As shown, this utility model is an assembly device for robot cross roller bearings, including an assembly frame 1. The front of the assembly frame 1 is provided with a clamping component 2 and a pressing drive component 3. The top of the assembly frame 1 is provided with a rotating guide component 4. The interior of the rotating guide component 4 is provided with a top material component 5 and a transfer component 6. A pressing limit component 7 is provided between the connecting ends of the top material component 5 and the transfer component 6.
[0037] The clamping assembly 2 is used to clamp and fix the outer ring of the bearing. The extrusion drive assembly 3 is used to extrude the inner ring of the bearing, so that the inner ring of the bearing driven by the extrusion drive assembly 3 drives the cage to rotate. The rotating guide assembly 4 is used to guide the roller to the mounting window of the outer ring of the bearing, so that the roller moves sequentially and at 90° to the cage slot. The transfer assembly 6 is used to transfer the roller to the bottom end of the top material assembly 5, so that the top material assembly 5 pushes the roller into the slot.
[0038] When installing the rollers into the bearing cage, the bearing ring with the cage is placed between the two clamping ends of the clamping assembly 2, so that the two clamping ends of the clamping assembly 2 clamp and fix the outer ring of the bearing. Then, the extrusion drive assembly 3 is driven, so that the extrusion end of the extrusion drive assembly 3 contacts the inner ring of the bearing. When installing the rollers, the external feeding device transports the rollers sequentially into the rotary guide assembly 4. The rollers in the rotary guide assembly 4 are moved to the bottom of the top material assembly 5 by the transfer assembly 6, so that the top material assembly 5 can push the rollers into the slots opened on the cage. After each roller is installed, the rotary guide assembly 4 will rotate 90°, and the extrusion end of the extrusion drive assembly 3 will drive the cage to rotate a certain angle through the inner ring of the bearing, and then repeat the above operation.
[0039] The inner and outer rings of the bearing are fixed by the clamping assembly 2 and the extrusion drive assembly 3. At the same time, the outer feeding device can move the roller to the bottom of the top material assembly 5 through the rotating guide assembly 4 and the transfer assembly 6. Thus, the top material assembly 5 pushes the roller into the slot opened on the cage through the installation window. Each time a roller is installed, the rotating guide assembly 4 will rotate 90°. At the same time, the extrusion drive assembly 3 drives the cage to rotate by the moving angle through the inner ring of the bearing. The above settings allow the roller to move automatically 90° into the slot on the cage. The whole process does not require manual intervention, thereby improving the accuracy and efficiency of roller installation.
[0040] In one embodiment, the clamping assembly 2 includes a bidirectional screw 201, which is rotatably connected to the inside of the assembly frame 1. A clamping frame 202 is threadedly connected to the outer surface of the bidirectional screw 201. Two clamping frames 202 are symmetrically arranged. An arc-shaped clamping plate 203 is fixedly connected to the inner side of the clamping frame 202. A clamping motor 204 is fixedly installed on the outer side of the clamping frame 202. The output end of the clamping motor 204 is fixedly connected to the bidirectional screw 201.
[0041] By placing the bearing ring between two arc-shaped clamping plates 203, and then driving the bidirectional screw 201 through the clamping motor 204, the rotating bidirectional screw 201 drives the two arc-shaped clamping plates 203 to move simultaneously towards the center position of the assembly frame 1 through the two clamping frames 202, thereby clamping and fixing the bearing outer ring with the two arc-shaped clamping plates 203. This setting ensures that the bearing outer ring will not rotate arbitrarily when installing the rollers, so that the installation window opened on the bearing outer ring can always correspond to the rotating guide assembly 4. At the same time, it also allows the rollers inside the rotating guide assembly 4 to move normally through the installation window into the slot opened on the cage.
[0042] In one embodiment, the extrusion drive assembly 3 includes a rotating cylinder 301, which is rotatably connected to the assembly frame 1. A plurality of movable plates 302 are movably connected to the outer side of the rotating cylinder 301. An arc-shaped top plate 303 is fixedly connected to one side of the movable plate 302. A drive disk 304 is rotatably connected inside the rotating cylinder 301. A plurality of first drive grooves 305 are opened on the front side of the drive disk 304. A drive rod 306 is movably connected inside the first drive groove 305. The drive rod 306 is fixedly connected to the corresponding movable plate 302. An extrusion motor 307 is fixedly installed at one end of the rotating cylinder 301. The output end of the extrusion motor 307 extends into the rotating cylinder 301 and is fixedly connected to the drive disk 304.
[0043] After clamping and fixing the outer ring of the bearing, the drive disk 304 is driven to rotate inside the rotating cylinder 301 by the extrusion motor 307. The rotating drive disk 304 can extrude several drive rods 306 through the first drive groove 305, so that the drive rods 306 can drive the corresponding moving plate 302 to move inside the rotating cylinder 301. At this time, the moving plate 302 can drive the arc-shaped top plate 303 to move synchronously, so that several arc-shaped top plates 303 come into contact with the inner ring of the bearing. After the installation of one roller is completed, the rotating cylinder 301 is rotated. At this time, the rotating cylinder 301 drives the inner ring to rotate through the moving plate 302 and the arc-shaped top plate 303. The rotating inner ring drives the cage to rotate synchronously, so that the next slot on the cage is aligned with the installation window, and then the next roller is installed.
[0044] In one embodiment, for the assembly frame 1 described above, an installation box 308 is fixedly installed on the back of the assembly frame 1. A driven gear 309 is provided inside the installation box 308. The driven gear 309 is fixedly connected to the rotating cylinder 301. A driving gear 310 meshes with the outer side of the driven gear 309. A drive motor 311 is fixedly installed on the back of the installation box 308. The output end of the drive motor 311 extends into the installation box 308 and is fixedly connected to the driving gear 310.
[0045] The drive motor 311 drives the drive gear 310 to rotate, and the rotating drive gear 310 drives the rotating cylinder 301 to rotate through the driven gear 309. The output end of the drive motor 311 is equipped with an encoder, which can automatically shut off after the drive motor 311 drives the rotating cylinder 301 to rotate a certain angle.
[0046] In one embodiment, the rotary material guide assembly 4 includes a mounting frame 401, which is fixedly mounted on the top of the assembly frame 1. A rotating frame 402 is rotatably connected inside the mounting frame 401. A guide tube 403 is fixedly connected to the top of the rotating frame 402, and the bottom end of the guide tube 403 extends into the interior of the rotating frame 402. A rotary motor 404 is fixedly mounted on the back of the mounting frame 401, and the output end of the rotary motor 404 is fixedly connected to the rotating frame 402.
[0047] A vibratory feeder is installed on the upper side of the feed tube 403. The discharge end of the vibratory feeder is connected to the top of the feed tube 403 via a metal spring hose. During terminal installation, a batch of terminals are fed into the feed tray, and then the vibratory feeder is driven. At this time, the vibratory feeder generates high-frequency vibration through a drive source such as an electromagnet, piezoelectric ceramic, or motor eccentric wheel, which transmits kinetic energy to the spiral track, causing the terminals to jump and climb along the track under the action of inertial force. At the same time, through the design of baffles, notches, or inclined surfaces on the track, combined with the vibration direction and the difference in the center of gravity of the parts, the posture of the terminals is screened and corrected, so that the terminals move into the interior of the metal spring hose in a directional arrangement. Simultaneously, the terminals move directly into the feed tube 403 under the guidance of the metal spring hose. When the terminals move from the lower end of the feed tube 403... After exiting, the terminal can be directly moved into the corresponding slot. When the guide tube 403 guides the terminal into the corresponding slot, the rotary motor 404 can drive the rotating frame 402 to rotate on the mounting frame 401. The rotating mounting frame 401 then drives the guide tube 403 to rotate 90°, so that the bottom end of the guide tube 403 can fit with the next slot. The rotatable guide tube 403 allows the terminal to move sequentially and at 90° angles into the slot. At the same time, since the guide tube 403 is connected to the vibratory feeder through a metal spring hose, the metal spring hose will not deform when the guide tube 403 rotates, so that the metal spring hose can continuously guide the terminal inside the vibratory feeder into the guide tube 403.
[0048] In one embodiment, the top material assembly 5 includes a top material rod 501, which is movably connected to a guide tube 403. A drive groove 502 is provided on the outer side of the guide tube 403. A connecting strip 503 is movably connected inside the drive groove 502. The inner side of the connecting strip 503 is fixedly connected to the top material rod 501. A drive plate 504 is fixedly connected to the outer side of the connecting strip 503. An electric push rod 505 is provided on the outer side of the guide tube 403. The output end of the electric push rod 505 is fixedly connected to the top end of the drive plate 504.
[0049] By driving the electric push rod 505, the electric push rod 505 drives the connecting bar 503 to move inside the drive groove 502 via the drive plate 504. The moving connecting bar 503 then drives the top material rod 501 to move inside the guide tube 403. At this time, the moving top material rod 501 can push the terminal at its bottom end, so that the terminal can move more smoothly into the slot.
[0050] In one embodiment, the transfer assembly 6 includes a transfer box 601, which is fixedly connected to the outside of the guide tube 403. A push tube 602 is movably connected inside the transfer box 601 corresponding to the guide tube 403. A drive groove 502 passes through the push tube 602 and the transfer box 601. A pull rod 603 is fixedly connected to the outside of the guide tube 403. One end of the pull rod 603 passes through the transfer box 601 and is fixedly connected to a connecting frame 604. A T-shaped support rod 605 is fixedly connected to the outside of the guide tube 403. The connecting frame 604 is movably connected to the T-shaped support rod 605. A return spring 606 is fixedly connected between the connecting frame 604 and the outside of the guide tube 403.
[0051] After the top of the ejector rod 501 moves to the lower side of the push tube 602, the terminal at the top of the ejector rod 501 is inside the push tube 602 under the action of the ejector rod 501. At this time, the connecting frame 604 moves under the action of external force. The moving connecting frame 604 pulls the push tube 602 through the pull rod 603, so that the push tube 602 can push the terminal inside into the transfer box 601. When the ejector rod 501 completes ejection and moves to the upper side of the push tube 602 again, it pulls the connecting frame 604. When the external force disappears, the reset spring 606 can pull the connecting frame 604, thereby causing the connecting frame 604 to reset under the guidance of the T-shaped support rod 605. At the same time, the connecting frame 604 pushes the push tube 602 back into the guide tube 403 through the pull rod 603. At this time, the terminal inside the push tube 602 can move downward under its own weight. The above settings enable the terminal at the top of the top rod 501 to move normally to the bottom of the top rod 501, thereby enabling the terminal to be fed normally.
[0052] In one embodiment, for the aforementioned transfer box 601, a T-shaped push rod 607 is movably connected to the outside of the transfer box 601. One end of the T-shaped push rod 607 extends into the interior of the transfer box 601 and is fixedly connected to a blocking block 608. A push spring 609 is fixedly connected between the top end of the T-shaped push rod 607 and the guide tube 403. A baffle rod 610 is movably connected inside the guide tube 403. One end of the baffle rod 610 passes through the guide tube 403 and is fixedly connected to the connecting frame 604.
[0053] When the push tube 602 moves the terminal into the transfer box 601, the push spring 609 pushes the blocking block 608 through the T-shaped push rod 607, allowing the blocking block 608 to move to one side of the connection between the transfer box 601 and the guide tube 403, while the push tube 602 blocks the connection on the other side. This arrangement prevents subsequent terminals from moving from the transfer box 601 under the action of the top rod 501 and not moving into the transfer box 601, thus avoiding jamming. When the push tube 602 moves into the connecting frame 6... When 04 is pushed to reset, the stop rod 610 moves to the inside of the guide tube 403 under the push of the connecting frame 604. At this time, the stop rod 610 can block the terminal moving down from the inside of the push tube 602. The terminal at this position will only be blocked by the top rod 501 when the top rod 501 moves down and the push tube 602 pushes the next terminal into the inside of the transfer box 601. This setting ensures that the terminal that has been transferred will not fall from the bottom of the guide tube 403 during the process of adjusting the angle of the guide tube 403 after the terminal installation is completed.
[0054] In one embodiment, the extrusion limiting assembly 7 includes a wedge block 701, which is provided on the outer side of the drive plate 504 and the inner wall of the connecting frame 604. A fixing plate 702 is fixedly connected to the outer side of the guide tube 403. A limiting rod 703 is movably connected to the top of the fixing plate 702. The bottom end of the limiting rod 703 passes through the fixing plate 702 and is rotatably connected to a ball bearing 704. A limiting hole 705 is opened at the top of the pulling rod 603 corresponding to the limiting rod 703. A connecting plate 706 is fixedly connected to the outer surface of the limiting rod 703. A limiting spring 707 is fixedly connected between the connecting plate 706 and the fixing plate 702. A lifting plate 708 is fixedly connected to the top of the limiting rod 703 corresponding to the wedge block 701.
[0055] When the drive plate 504 moves the top rod 501 to the lower side of the push tube 602 via the connecting bar 503, the wedge block 701 on the drive plate 504 can press against the wedge block 701 inside the connecting frame 604. As the top rod 501 moves downward, the two wedge blocks 701 cooperate to push the connecting frame 604 outward, thereby causing the connecting frame 604 to pull the push tube 602 into the transfer box 601 via the pull rod 603. In the above configuration, the push tube... There is a movable gap between the bottom of tube 602 and the bottom of the inner wall of transfer box 601. This setting allows the push tube 602 to properly push the terminal, which moves downward under the action of the top rod 501, into the interior of transfer box 601. After the push tube 602 has completely moved the terminal into the interior of transfer box 601, the limiting hole 705 at the top of the pull rod 603 corresponds vertically to the limiting rod 703. At this time, the limiting spring 707 pushes the limiting rod 703 downward through the connecting plate 706, thereby... This allows the limiting rod 703 to move directly into the limiting hole 705 and limit the push tube 602 via the pulling rod 603, thereby preventing the connecting frame 604 from resetting under the elastic force of the return spring 606 after the two wedge blocks 701 separate, thus preventing the top rod 501 from moving back to the upper side of the push rod 603; when the top rod 501 moves back to the upper side of the push tube 602, the wedge blocks 701 on the drive plate 504 can lift the plate 702. 08 is lifted, so that the lifting plate 708 can pull the limiting rod 703 upward, and the limiting rod 703 moves out of the limiting hole 705. At this time, the limiting rod 703 no longer limits the pulling rod 603. At the same time, the connecting frame 604 is reset by the elastic force of the return spring 606 through the pulling rod 603 to drive the push tube 602 to reset. The entire process can be completed by driving the electric push rod 505, thus making the linkage of the whole structure strong.
[0056] Through the above technical solution, 1. The clamping assembly 2 and the extrusion drive assembly 3 complete the fixation of the inner and outer rings of the bearing. At the same time, the outer feeding device can move the roller to the bottom of the top material assembly 5 through the rotating guide assembly 4 and the transfer assembly 6. Thus, the top material assembly 5 pushes the roller into the slot opened on the cage through the installation window. Each time a roller is installed, the rotating guide assembly 4 will rotate 90°. At the same time, the extrusion drive assembly 3 drives the cage to rotate by a moving angle through the inner ring of the bearing. The above settings allow the roller to automatically move 90° into the slot on the cage. The whole process does not require manual intervention, thereby improving the accuracy and efficiency of roller installation; 2. The electric push rod 505, the drive plate 504 and the connecting bar 503 After the top material rod 501 is driven to the lower side of the push tube 602, the two wedge blocks 701 on the drive plate 504 and the connecting frame 604 cooperate to push the connecting frame 604, so that the connecting frame 604 pushes the terminal into the transfer box 601 through the pull rod 603 and the push tube 602. When the top material rod 501 moves to the upper side of the push tube 602 again, the limit rod 703 releases the limit on the pull rod 603. At this time, the connecting frame 604, under the elastic force of the return spring 606, pushes the push tube 602 and the terminal into the guide tube 403 again through the pull rod 603. The above settings allow the terminal at the upper end of the top material rod 501 to move normally to the lower end, so that the guide tube 403 can discharge material normally when the top material rod 501 can push material normally.
