The traditional bearing assembly process mainly relies on manual operation. Assembly workers need to manually place the semi-finished bearings at a specific workstation, and then use stamping equipment to press them into shape, and finally complete the subsequent transfer process. This manual assembly method has many disadvantages.

[0011] Compared with the prior art, the present invention has the following beneficial effects: (1) A bearing automatic assembly robot system, which can push the base plate and the device connected to the top to different positions by setting the base plate above the pulley and utilizing the sliding characteristics of the pulley. The first rack is meshed with the outer surface of the first gear. When the first gear rotates, it can slide smoothly in the horizontal direction along the outer surface of the first rack, and the first rotating column fixedly connected to the top of the first gear will also move accordingly, thereby driving the synchronous movement of the second rotating column connected to the top of the first rotating column.
[0012] (2) A bearing automatic assembly robot system, which allows the first roller at the bottom of one end of the support plate to roll in the groove at the top of the first slide rail, and the second rollers correspondingly connected on both sides of the support plate slide in the grooves on both sides of the first slide rail. The coordination of multiple rollers not only effectively reduces the friction resistance during sliding and increases the sliding speed, but also can accurately adjust the position of the lifting device at the top of the support plate through multi-directional limiting and support.
[0013] (3) A bearing automatic assembly robot system, which can move horizontally synchronously with the support plate by arranging the second slide rail and the second rack on the top of the support plate respectively. When the motor drives the two second gears and the third roller to slide in the vertical direction, the second gear and the third roller will only slide on the outer surface of the second rack and the second slide rail respectively, ensuring that the entire sliding process follows the preset track. Since the bottom end of the second gear is connected to the motor, and the motor is fixedly connected to the connecting rod, when the second gear slides up and down along the outer surface of the second rack, the connecting rod will move up and down synchronously along the outer surface of the second rotating column.
[0014] (4) A bearing automatic assembly robot system, which sets a transmission belt on the outer surface of two rotating blocks. When the motor drives one of the rotating blocks to rotate, the connection function of the transmission belt can ensure that the two rotating blocks rotate synchronously and improve the transmission efficiency. At the same time, the robotic arm connected to the top of the rotating block swings back and forth, and drives the rotating rod movably connected to the other end of the robotic arm to rotate around the axis, so that the gripping device fixedly connected to the bottom of the rotating rod can achieve multi-angle adjustment.
[0015] (5) A bearing automatic assembly robot system, which sets a polygonal block at the bottom end of a rotating rod. The gripping device can realize height adjustment and angle swing synchronously with the rotating rod, and accurately locate the bearing to be grasped. When the motor drives the threaded rod to rotate, the first elliptical plate connected to the outer surface of the threaded rod will move upward along the axial direction, and pull the second elliptical plate movably connected at the grooves at both ends to rise synchronously. Since the second elliptical plate is movably connected to the top end of the bending rod, and the bending rod has a 90° bend structure, when its top end rises, the bottom end will produce a horizontal displacement toward the center, and then the clamp connected to the bottom of the bending rod will move synchronously toward the center, realizing the embracing grasping of the bearing.

By placing the base plate 612 above the pulley 611, the sliding characteristics of the pulley 611 can be used to push the base plate 612 and the device connected to the top to different positions. The first rack 614 is meshed with the outer surface of the first gear 615. When the first gear 615 rotates, it can slide smoothly horizontally along the outer surface of the first rack 614, and the first rotating column 616 fixedly connected to the top of the first gear 615 will also move, thereby driving the synchronous movement of the second rotating column 626 connected to the top of the first rotating column 616. The top of the first gear 615 is fixedly connected to the bottom of the first rotating column 616.
[0021] The outer surface of the top of the first rotating column 616 is provided with a support plate 617, and the outer surface of the top of the first rotating column 616 is connected to one end of the support plate 617. A lifting device 62 is provided on the top of the support plate 617, and the top of the support plate 617 is fixedly connected to the bottom of the lifting device 62. A first roller 618 is provided on the central raised portion of the bottom of the other end of the support plate 617, and the central raised portion of the bottom of the other end of the support plate 617 is movably connected to both ends of the first roller 618, and the bottom of the first roller 618 is movably connected to the groove at the top of the first slide rail 613.

By allowing the first roller 618 at the bottom of one end of the support plate 617 to roll in the groove at the top of the first slide rail 613, the second rollers 6110 correspondingly connected on both sides of the support plate 617 slide in the grooves on both sides of the first slide rail 613. This combination of multiple rollers not only effectively reduces frictional resistance during sliding and increases sliding speed, but also can accurately adjust the position of the lifting device 62 at the top of the support plate 617 through multi-directional limiting and support, significantly improving the stability and working efficiency of the entire device. The outer surfaces of the two second rollers 6110 are movably connected to the grooves on both sides of the first slide rail 613.
[0022] The lifting device 62 includes a second slide rail 621, a second rack 622 is provided at the rear end of the second slide rail 621, and the rear end of the second slide rail 621 is fixedly connected to the front end of the second rack 622, and the bottom of the second slide rail 621 and the second rack 622 is fixedly connected to the top of the support plate 617, and two second gears 623 and a third roller 624 are provided on one side of the second slide rail 621 and the second rack 622, and one side of the second slide rail 621 and the second rack 622 are meshed with the outer surfaces of the two second gears 623 and the third roller 624, a motor 625 is provided at the rear end of the two second gears 623, and the rear end of the two second gears 623 is movably connected to the outer side of the motor 625, a second rotating column 626 is provided on the raised part at one end of the top of the second slide rail 621, and the raised part at one end of the top of the second slide rail 621 is connected to the second The top of the rotating column 626 is movably connected. By placing the second slide rail 621 and the second rack 622 on the top of the support plate 617, the rotating column 626 can move horizontally in sync with the support plate 617. When the motor 625 drives the two second gears 623 and the third roller 624 to slide vertically, the second gear 623 and the third roller 624 will only slide on the outer surfaces of the second rack 622 and the second slide rail 621, respectively, ensuring that the entire sliding process follows the preset track. Because the bottom end of the second gear 623 is connected to the motor 625, which is in turn fixedly connected to the linkage rod 627, when the second gear 623 slides up and down along the outer surface of the second rack 622, the linkage rod 627 will also move up and down synchronously along the outer surface of the second rotating column 626, thereby achieving precise adjustment and stable operation of the lifting device 62. The bottom of the second rotating column 626 is connected to the top of the first rotating column 616.
[0023] The outer surface of the second rotating column 626 is provided with a connecting rod 627, and the outer surface of the second rotating column 626 is connected to the center of the connecting rod 627 through the center, the bottom end of the connecting rod 627 is fixedly connected to the outside of the motor 625, and two rotating blocks 628 are provided on the top of the connecting rod 627, and the top of the connecting rod 627 is movably connected to the bottom of the two rotating blocks 628, and the outer surfaces of the two rotating blocks 628 are provided with bandages 629, and the outer surfaces of the two rotating blocks 628 are movably connected to the inner surfaces of the bandages 629, a mechanical arm 6210 is provided on the top of one of the rotating blocks 628, and the top of one of the rotating blocks 628 is movably connected to one end of the mechanical arm 6210, and the bottom of the other end of the mechanical arm 6210 is provided with a rotating rod 6 211, and the bottom of the other end of the robotic arm 6210 is movably connected to the top of the rotating rod 6211. The bottom of the rotating rod 6211 is provided with a gripping device 63. By providing a transmission belt 629 on the outer surface of the two rotating blocks 628, when the motor 625 drives one of the rotating blocks 628 to rotate, the connection function of the transmission belt 629 can ensure that the two rotating blocks 628 rotate synchronously, thereby improving transmission efficiency. At the same time, the robotic arm 6210 connected to the top of the rotating block 628 swings back and forth, driving the rotating rod 6211 movably connected to the other end of the robotic arm 6210 to rotate about its axis, so that the gripping device 63 fixedly connected to the bottom of the rotating rod 6211 can achieve multi-angle and azimuth adjustment, accurately grasping the formed bearing shell at the end of the conveyor device 5. The bottom of the rotating rod 6211 is fixedly connected to the top of the gripping device 63.
[0024] The clamping device 63 includes a polygonal block 631, the top of the polygonal block 631 is fixedly connected to the bottom of the rotating rod 6211, a threaded rod 632 is provided at the center groove of the polygonal block 631, and the center groove of the polygonal block 631 is movably connected to the two ends of the threaded rod 632, a first elliptical plate 633 is provided on the outer surface of the threaded rod 632, and the outer surface of the threaded rod 632 is movably connected to the center of the first elliptical plate 633, a second elliptical plate 634 is provided at the grooves at both ends of the first elliptical plate 633, and the grooves at both ends of the first elliptical plate 633 are movably connected to the two sides of the top of the second elliptical plate 634.
[0025] The bottoms of the two second elliptical plates 634 are provided with curved rods 635 on both sides, and the bottoms of the two second elliptical plates 634 are movably connected to the grooves at the tops of the curved rods 635. The bottoms of the two curved rods 635 are provided with clamps 636, and the bottoms of the two curved rods 635 are movably connected to one end of the top of the clamps 636. The other ends of the tops of the two clamps 636 are provided with third elliptical plates 637, and the other ends of the tops of the two clamps 636 are movably connected to the bottoms of the third elliptical plates 637. By setting the polygonal block 631 at the bottom end of the rotating rod 6211, the clamping device 63 can rotate with the rotating rod. 6211 achieves simultaneous height adjustment and angular swing, precisely locating the bearing to be grasped. When the motor 625 drives the threaded rod 632 to rotate, the first elliptical plate 633 connected to the outer surface of the threaded rod 632 moves upward axially, pulling the second elliptical plate 634, which is flexibly connected to the grooves at both ends, to rise synchronously. Because the second elliptical plate 634 is flexibly connected to the top of the curved rod 635, which has a 90° bend, its top rises, causing the bottom end to move horizontally toward the center. This then causes the clamp 636 connected to the bottom of the curved rod 635 to move toward the center, achieving an encircling grasp of the bearing. The tops of the two third elliptical plates 637 are flexibly connected to the bottom of the polygonal block 631.
[0026] The working principle of the present invention is as follows: First, the pushing mechanism 2 is activated to push the semi-finished bearing shell placed at the initial position to the pressing position above the mounting platform 3, completing the initial positioning and transfer of the bearing shell. The driving device 4 on the top of the mounting platform 3 then drives the internally connected pressing device to move in the vertical direction, applying pressure to the semi-finished bearing shell at the pressing position to form it. During the pressing process, the pressure and stroke of the pressing device are precisely controlled by the control system 7 to ensure the quality of the bearing shell forming. The finished bearing shell passes through the exit of the mounting platform 3 and enters the top of the conveyor 5, where it is transported to the rear end. At this point, the distribution device 6 begins operation. The pulley 611 in the conveyor 61 drives the bottom plate 612 and its top assembly, allowing the entire transport device 61 to move. Once the desired position is reached, the first gear 615 slides along the outer surface of the first rack 614, driving the rotation of the first rotating column 616. This, in turn, causes the second rotating column 626, connected to the first rotating column 616, to move together, adjusting the horizontal position of the lifting device 62. The second gear 623 in the lifting device 62 is driven by the motor 625 and slides up and down along the outer surface of the second rack 622. At the same time, the third roller 624 also rolls on the outer surface of the second slide rail 621 to ensure that the entire sliding process follows the preset track. Since the bottom end of the second gear 623 is connected to the motor 625, and the motor 625 is fixedly connected to the connecting rod 627, when the second gear 623 slides up and down along the outer surface of the second rack 622, the connecting rod 627 will move up and down synchronously along the outer surface of the second rotating column 626. Similarly, the motor 625 will also drive the two rotating blocks 628 to rotate. After the rotation, the 628 will make the mechanical arm 6210 and the clamping device 63 swing back and forth, so that the clamping device 63 can be rotated to the top of the bearing at the tail end of the conveying device 5 after adjusting the height. Driven by the motor 625, the threaded rod 632 in the gripping device 63 rotates, driving the first elliptical plate 633, which is movably connected at both ends, to move upward. Subsequently, the first elliptical plate 633 quickly pulls the second elliptical plate 634 upward synchronously, and the second elliptical plate 634 pulls the top of the curved rod 635 upward. Because the curved rod 635 is in a 90-degree folded state, its top end rises while its bottom end only deviates toward the center, thereby pulling the clamp 636 toward the center to grasp the bearing. After grasping the bearing, the transport device 61 and the lifting device 62 cooperate again to move the bearing to the next station, completing the bearing transfer.
[0027] During the entire assembly process, the intelligent detection unit monitors the operating data and bearing status of each link in real time, and feeds back the data to the control system 7. The control system 7 dynamically adjusts each actuator, such as the pushing mechanism 2, the driving device 4, the distribution device 6, etc. according to the feedback data to ensure that the automated assembly process of the bearing is carried out efficiently, accurately and stably.
[0028] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
