Description

Technical Field

[0001] The present invention relates to the technical field of rolling bearing manufacturing equipment, and specifically relates to an automatic assembly device for rolling bearings. Background Art

[0002] Rolling bearings are key components of mechanical transmission systems. They rely on the rolling of rolling elements between the inner and outer rings to achieve low-friction movement and are widely used in many fields such as automobiles, aerospace, and industrial machinery. As an important part of rolling bearings, bearing covers can not only prevent grease leakage, isolate the intrusion of external dust and impurities, but also provide a stable operating environment for the rolling elements, thus ensuring the reliable performance of the bearings under high-speed rotation conditions. Currently, the assembly of bearing covers and bearings is usually completed by a grease injection and capping integrated machine.

[0003] However, bearing seals are usually stored in storage containers and fed by sliding through channels. However, due to the fixed size of the storage containers, the gap between the placed bearing covers and the storage containers is too small, increasing the difficulty of the placement operation and affecting the feeding efficiency and convenience; when the bearings are moved, multiple pusher blocks in the front, back, left, and right directions on the grease injection and capping integrated machine are used for feeding. The pusher blocks are fixed to the mounting rods by bolts, making the operation of overhaul and replacement of the pusher blocks relatively cumbersome, affecting the overhaul efficiency, and further affecting the overall maintenance progress of the grease injection and capping integrated machine; in the pressing process, the bearing covers are usually clamped on the pressing columns. Due to the vibration of the grease injection and capping integrated machine generated during grease injection, and the inertial force generated during the rapid reciprocating movement of the pressing columns, the bearing covers are prone to slipping during the operation, affecting the assembly efficiency.

[0045] Specifically, as Figure 1 — Figure 3As shown, the anti-falling structure 5 includes two anti-falling rods 501 slidably connected to the press-fitting column 10 and two connecting shafts 502 rotatably connected to the anti-falling rods 501. A turntable 503 is rotatably connected inside the press-fitting column 10. A driving groove 504 is provided on the turntable 503. The two connecting shafts 502 are respectively in rolling cooperation with the two driving grooves 504. When the turntable 503 rotates, the two connecting shafts 502 roll in the driving grooves 504, causing the two anti-falling rods 501 to move away from each other and extend out of the press-fitting column 10.

The first gear 605 is engaged with the toothed ring 607. A positioning plate 604 is fixedly connected to the connecting ring 602. The sliding of the first rack 603 drives a plurality of positioning plates 604 to move towards the middle of the storage barrel 601 to position the bearing cover so that it is located at the central position of the storage barrel 601, facilitating the feeding.

The handling structure 7 includes a handling column 701 detachably connected to the storage barrel 601 and two second rotating shafts 702 rotatably connected to the handling column 701. A stop block 703 is installed on the second rotating shaft 702. The bearing covers are carried by the handling column 701.

A second gear 704 is fixedly connected to the second rotating shaft 702. A second rack 705 is slidably connected to the handling column 701. The second gear 704 is engaged with the second rack 705. A pulling plate 706 is fixedly connected to the second rack 705. A second lead screw 707 is slidably connected to the pulling plate 706. Two threaded holes 708 are provided on the handling column 701. The second lead screw 707 is in threaded cooperation with one of the threaded holes 708. The second lead screw 707 is in threaded cooperation with the other threaded hole 708 to fix the slid second rack 705, improving the stability. A connecting plate 709 is fixedly connected to the handling column 701. The pulling plate 706 is slidably connected to the connecting plate 709. Two sliding rods 710 are slidably connected inside the handling column 701. A sliding plate 711 is fixedly connected to the sliding rod 710. The sliding plate 711 is slidably connected to the handling column 701. A third lead screw 712 is rotatably connected to the handling column 701. The sliding plate 711 is threadedly connected to the third lead screw 712. The thread directions at both ends of the third lead screw 712 are opposite. The thread directions at both ends of the third lead screw 712 are opposite.The threaded drive makes the two slide bars 710 move away from each other. The slide bars 710 drive the slide plate 711 to slide, and the position of the slide plate 711 is adjusted according to the bearing caps of different sizes, so as to prevent the bearing cap from shaking too much on the handling column 701 and slipping off from the stop block 703 during handling.

[0047] When the present invention is in use, when bearings are loaded, the bearings are first conveyed to the grease injection and gland pressing integrated machine 1 by a conveying device. Subsequently, the first driving member 210 (preferably a hydraulic rod) is started, and its telescopic end extends to drive the fixed rod 209 to move. The fixed rod 209 further drives the two connecting columns 202 to slide on the slide table 201. At the same time, the second driving member 211 (preferably a hydraulic rod) is started, and its telescopic end extends to drive the slide table 201 to slide along the guide rail 212. The guide rail 212 ensures the smooth sliding of the slide table 201. When the slide table 201 moves, it drives the pusher block 206 to move through the mounting plate 203. With the movement cooperation of the slide table 201 and the connecting column 202, the pusher block 206 realizes the pushing of the bearings, and the bearings are pushed to different processing stations. When the bearings are pushed below the grease injection device 8, grease injection is carried out through the grease injection device 8. Then it moves to the bottom of the first pressing device 9, and the pressing device 9 cooperates with the feeding mechanism to feed the bearing cap into it and perform pressing. After that, it continues to be conveyed to the clamping and flipping device for turning over, and then conveyed below the next pressing device 9 to press the other side of the bearing, completing the assembly of the bearing and the bearing cap.

[0048] If it is necessary to adjust the distance between every two pusher blocks 206 according to the bearing size, the first lead screw 304 can be rotated. When it rotates, it drives the adjusting plate 301 to slide through the threaded drive. The adjusting plate 301 is in sliding fit with the guide rod 303, and the guide rod 303 ensures the smooth sliding of the adjusting plate 301. When the adjusting plate 301 slides, the drive shaft 207 on the slider 205 is in rolling fit with the inclined groove 302. Since the two inclined grooves 302 in rolling fit with every two drive shafts 207 are in an "eight" shape, the slider 205 drives the two pusher blocks 206 to slide towards or away from each other. The pusher blocks 206 slide on the connecting rod 305 in the slide frame 204, and the connecting rod 305 makes the slider 205 slide smoothly. When the pusher blocks 206 slide towards each other, they are also in sliding fit between the two guide plates 208. The guide plates 208 are convenient for cooperating with the pusher blocks 206 to fix the bearings, preventing the bearing caps from shifting during assembly, improving the processing quality, and at the same time adjusting the position of the pusher blocks 206 to adapt to bearings of different sizes.

[0049] When the pusher block 206 wears out and needs to be replaced, press down the pressing rod 405. The pressing rod 405 is in sliding fit with the guide post 406, and the guide post 406 ensures the smooth sliding of the pressing rod 405. When the pressing rod 405 moves downward, the first tension spring 407 elongates, and at the same time drives the guide seat 403 to move downward. The guide seat 403 on the pressing frame 404 is trapezoidal in structure, and then drives the mounting block 402 to move downward, so that the mounting block 402 is no longer engaged with the fixed block 401. At this time, the pusher block 206 can be removed from the slider 205. By engaging the mounting block 402 with the fixed block 401, it is convenient to quickly disassemble and assemble the pusher block 206, improve the replacement efficiency, and the mounting block 402 and the guide seat 403 can slide, which will not affect the position adjustment of the pusher block 206;

[0050] During the press-fitting process, the hydraulic rod on the press-fitting device 9 drives the press-fitting column 10 to move downward. When the press-fitting column 10 holds the bearing cover on it, while the press-fitting column 10 rises, start the third driving member 506 (preferably a motor). The output shaft of the motor rotates to drive the transmission shaft 505 to rotate, and the transmission shaft 505 rotates to drive the turntable 503 to rotate. When the turntable 503 rotates, the two connecting shafts 502 roll in the driving groove 504, so that the two anti-falling rods 501 move away from each other and extend out of the press-fitting column 10. By extending the anti-falling rods 501, it is possible to prevent the bearing cover from slipping off the press-fitting column 10 during the movement of the press-fitting column 10, and improve the smoothness of processing;

[0051] When the storage bucket 601 stores materials, first, the bearing caps are carried by the carrying column 701. Multiple bearing caps are sleeved on the carrying column 701, and the bottom is blocked by two stoppers 703 to prevent them from falling. After the carrying column 701 is inserted into the storage bucket 601, the pull plate 706 is pulled. The pull plate 706 drives the second rack 705 to slide, and at the same time, it slides in cooperation with the connecting plate 709. The connecting plate 709 ensures the smooth sliding of the pull plate 706. When the second rack 705 slides, it drives two second gears 704 to rotate. The rotation of the second gears 704 drives the rotation of the second rotating shaft 702. The rotation of the second rotating shaft 702 causes the stopper 703 to rotate and no longer block the bearing caps. At this time, the bearing caps slide between multiple positioning plates 604. Then, the second lead screw 707 is threadedly engaged with another threaded hole 708 to fix the slid second rack 705 and improve the stability. At the same time, the third lead screw 712 can be rotated by an inner hexagonal wrench. Since the thread directions at both ends of the third lead screw 712 are opposite, the thread drives two slide rods 710 to move away from each other. The slide rods 710 drive the sliding of the slide plate 711. The position of the slide plate 711 is adjusted according to the bearing caps of different sizes to prevent the bearing caps from shaking too much on the carrying column 701 and falling off from the stopper 703 during handling. After that, the carrying column 701 can be taken out. The pull rod 613 is pulled. The pull rod 613 drives the limit post 610 to move through the sliding column 609, so that the limit post 610 no longer engages with the limit hole 611 on the storage bucket 601. At this time, the toothed ring 607 is driven to rotate by the guide frame 608. The rotation of the toothed ring 607 drives the rotation of the first gear 605. The rotation of the first gear 605 drives the first rack 603 to slide in the connecting ring 602. The sliding of the first rack 603 drives multiple positioning plates 604 to move towards the middle of the storage bucket 601 to position the bearing caps and make them located at the central position of the storage bucket 601, which is convenient for blanking. The positioning plates 604 can move. When placing, they can be moved close to the inner wall of the storage bucket 601 and then positioned. At the same time, they can adapt to bearing caps of different sizes, improving the practicability.
