Description

Technical Field

[0001] The invention relates to the technical field of bearing assembly, and in particular to a bearing processing and assembly auxiliary structure. Background Art

[0002] The bearing is mainly composed of four basic components: steel balls, inner ring, outer ring and retaining frame. The steel balls are located between the inner ring and the outer ring. During manual assembly, the steel balls need to fit the inner ring and the inner wall of the outer ring during the installation process. Then the steel balls are placed at the largest gap between the inner ring and the outer ring. Then the inner ring is pushed so that the inner ring and the outer ring are coaxial. Then the retaining frame is placed in the gap between the inner ring and the outer ring to limit the steel balls.

[0003] However, since the steel ball slots on the retaining frame are arranged at equal distances, the steel balls are piled up in one place when the retaining frame is placed, which will cause the steel ball slots on the retaining frame to not correspond to the steel balls. At this time, the staff needs to move the steel balls so that the steel balls are distributed at equal distances along the inner ring. The operation is cumbersome and also reduces the processing and assembly efficiency of the bearing. Summary of the invention

[0017] Beneficial effects of the present invention:

[0018] 1. By setting an equidistant connector, the telescopic cylinder is extended to rotate the transmission shaft 180 degrees. During this process, the supporting frame is first moved upward, and then the second movable arc block and multiple first movable arc blocks are moved to the bottom of the multi-tube. When the steel ball falls from the multi-tube, the steel ball will fall to the inside of the groove. When the telescopic cylinder is contracted, the steel ball is first distributed equidistantly around the inner ring of the bearing as the second movable arc block rotates, and then the first movable arc block, the second movable arc block, and the positioning arc block are moved to the bottom of the outer ring placement frame, thereby achieving the effect of equidistant distribution of the steel balls.

When the rotation angle of the transmission coupling exceeds 90 degrees, the protrusion of the cam will face upward, and the supporting frame cannot move. In this process, the cam squeezes and guides the U-shaped bayonet pin through the guide annular groove, so that the U-shaped bayonet pin drives the third piston rod to move upward, so that the aqueous solution inside the cavity enters the rectangular connecting chamber due to the squeezing of the third piston rod, so that the rectangular plug rod drives the fixing plate to move in the direction away from the center of the positioning column, so that the inner ring placement frame drives the inner ring of the bearing to move, so that the outer wall of the inner ring of the bearing can be fitted with the inner wall of the outer ring of the bearing. Similarly, when the telescopic cylinder contracts, it will first drive the inner ring placement frame to recover, so that the inner ring of the bearing first limits the steel balls that fall between the outer ring and the inner ring, and then diffuses the steel balls between the outer ring and the inner ring, further improving the stability of the steel balls moving between the inner ring and the outer ring.

[0036] In this embodiment, the outer ring of the bearing is first placed on the inner side of the outer ring placement frame 2, and then the inner ring of the bearing is placed on the inner ring placement frame 3. At this time, the first movable arc block 606, the second movable arc block 607, and the positioning arc block 613 are moved upward by starting the equidistant connector, so that the first movable arc block 606, the second movable arc block 607, and the positioning arc block 613 are moved between the outer ring and the inner ring of the bearing, and then the first movable arc block 606, the second movable arc block 607, and the positioning arc block 613 are moved upward by starting the equidistant connector.

One side of the fan-shaped guide wheel 604 is provided with a fan-shaped annular groove 605 along the edge of the fan-shaped guide wheel 604. Both sides of the positioning column 5 are provided with guide connecting plates 623 located above the U-shaped frame plate 625. The end of the guide connecting plate 623 away from the positioning column 5 is plugged with a liquid storage cylinder 629. The liquid storage cylinder 629 is provided with a second piston rod 626 extending to the bottom of the liquid storage cylinder 629. The second The piston rod 626 is provided with a return spring 628 connected to the liquid storage cylinder 629, the bottom of the second piston rod 626 is provided with a card pin 624 slidably connected to the fan-shaped ring groove 605, and one side of the second piston rod 626 is provided with a plug rod 627 connected to the guide connecting plate 623, and a guide groove 609 is provided on the positioning column 5. The positioning column 5 is slidably connected to a support frame 610 located above the guide connecting plate 623 through the guide groove 609, and an inner link ring 611 is installed on the outer side of the support frame 610. The outer link ring 612 located on the outer side of the inner link ring 611 is provided on the support frame 610, and the top of the support frame 610 is rotatably connected to the positioning frame 610. The spur gear ring 618 outside the positioning column 5, the top of the spur gear ring 618 is installed with a positioning rod 616, the positioning arc block 613 is fixedly connected to the outer link ring 612, and a plurality of first movable arc blocks 606 are slidably connected between the inner link ring 611 and the outer link ring 612. A plurality of arc-shaped telescopic rods 615 are arranged between the positioning arc block 613 and the first movable arc block 606 and between the plurality of first movable arc blocks 606. The second movable arc block 607 is installed at one end of the positioning rod 616 away from the center of the spur gear ring 618 and is slidably connected to the inner link ring 611 and the outer link ring 612. The top of the supporting frame 610 is provided with an movable The plug cylinder 622 has a first piston rod 621 inserted into the inner side of the piston cylinder 622, and a second shifting spur rack 619 meshing with the spur gear ring 618 is arranged at one end of the first piston rod 621 away from the piston cylinder 622, and a conduit 620 connected to the liquid storage cylinder 629 is arranged at one end of the piston cylinder 622 away from the first piston rod 621, a telescopic cylinder 601 is arranged on the inner side of the support seat 1, and an output end of the telescopic cylinder 601 is connected to a first shifting spur rack 602 meshing with the transmission spur gear 603, a partition plate 608 is installed on the top of the first movable arc block 606, and a groove 614 is opened on the top of the first movable arc block 606.

[0038] In this embodiment, the telescopic cylinder 601 is started, and the first shifting spur rack 602 drives the transmission spur gear 603 to rotate 180 degrees through the extension of the telescopic cylinder 601. When the fan-shaped guide wheel 604 rotates with the transmission coupling shaft 617, the fan-shaped annular groove 605 guides the card pin 624, so that the card pin 624 is squeezed and guided by the fan-shaped annular groove 605 and moves upward, so that the card pin 624 drives the support frame 610 to move upward through the return spring 628 and the liquid storage cylinder 629, so that the first movable arc block 606, the second movable arc block 607, and the positioning arc block 613 move to between the outer ring of the bearing and the inner ring of the bearing as the support frame 610 moves upward. When the transmission coupling shaft 617 rotates forty-five degrees, the card pin 624 is pushed upward by the return spring 628 and the liquid storage cylinder 629. When the supporting frame 610 moves to the highest point at 90 degrees, the fan-shaped annular groove 605 continues to rotate, and the second piston rod 626 will move relative to the liquid storage cylinder 629. When the transmission shaft 617 rotates 90 degrees, the aqueous solution inside the liquid storage cylinder 629 completely enters the piston cylinder 622, so that the second piston rod 626 pushes the aqueous solution inside the liquid storage cylinder 629 into the piston cylinder 622 through the conduit 620, so as to move the first piston rod 621 away from the piston cylinder 622. In this way, the second shifting spur rack 619 can shift the spur gear ring 618 to rotate, so that the positioning rod 616 drives the second movable arc block 607 to move toward the positioning arc block 613, so as to make the second movable arc block 607 and multiple first movable arc blocks 607 move. The arc block 606 moves to the bottom of the multi-tube 4. When the steel ball falls from the multi-tube 4, the steel ball will fall to the inside of the groove 614. When the telescopic cylinder 601 contracts, the second piston rod 626 will first move downward relative to the liquid storage cylinder 629 under the action of the elastic restoring force of the reset spring 628, so that the positioning rod 616 drives the second movable arc block 607 to rotate and recover. At this time, the second movable arc block 607 drives the first movable arc block 606 to rotate through the multi-section arc telescopic rod 615. When the second movable arc block 607 recovers, the second movable arc block 607, the multiple first movable arc blocks 606 and the positioning arc block 613 are equidistantly distributed along the center of the outer ring 612. In this process, the partition plate 608 drives the groove 61 4 moves, so that the steel balls are equidistantly distributed around the inner ring of the bearing as the second movable arc block 607 rotates. As the telescopic cylinder 601 continues to contract, the second piston rod 626 will drive the liquid storage cylinder 629 to move downward, so that the supporting frame 610 drives the first movable arc block 606, the second movable arc block 607, and the positioning arc block 613 to move downward, so that the first movable arc block 606, the second movable arc block 607, and the positioning arc block 613 can be moved to the bottom of the outer ring placement frame 2, thereby achieving the effect of equidistant distribution of the steel balls. When the retaining frame is installed between the outer ring and the inner ring of the bearing, the slot therein can be quickly buckled on the outside of the steel balls to improve the transfer efficiency of the bearing.

[0039] Please refer to Figure 3 , Figure 8 The tops of the first movable arc block 606 , the second movable arc block 607 , and the positioning arc block 613 are all provided with grooves 614 and partitions 608 , and a buffer pad is laid on the inner side of the groove 614 .

[0040] In this embodiment, this structure is provided so that the steel ball is cushioned by the buffer pad when it falls to the inside of the groove 614, thereby preventing the steel ball from bouncing up after falling. At the same time, when the first movable arc block 606 and the second movable arc block 607 rotate, the partition plate 608 drives the balls on the first movable arc block 606 and the second movable arc block 607 to move, thereby improving the stability of the balls moving with the second movable arc block 607 and the first movable arc block 606.

[0041] Please refer to Figure 3 , Figure 4 The inner ring 611, the outer ring 612, and the positioning column 5 are coaxial in center, and the center of the multi-section arc telescopic rod 615 is coaxial with the center of the positioning column 5.

[0042] In this embodiment, when the positioning rod 616 rotates, the second movable arc block 607 is driven to rotate so that the second movable arc block 607 pulls the first movable arc block 606. As the second movable arc block 607 moves, the distances between the first movable arc block 606 and the second movable arc block 607, the distances between the second movable arc block 607 and the positioning arc block 613, and the adjacent first movable arc blocks 606 are equal, so that the first movable arc block 606, the second movable arc block 607 and the positioning arc block 613 are distributed at equal distances.

[0043] Please refer to Figure 3 , Figure 4 The width of the positioning arc block 613 is smaller than the distance between the outer wall of the inner ring 611 and the inner wall of the outer ring 612, and the curvature of the groove 614 is equal to the curvature of the bottom of the steel ball.

[0044] In this embodiment, this structure is provided so that when the second movable arc block 607 moves between the outer ring of the bearing and the inner ring of the bearing, only the bottom of the fallen steel ball is supported, thereby preventing the second movable arc block 607 from rubbing against the outer ring of the bearing and the inner ring of the bearing during movement.

[0045] Please refer to Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7The sequential moving unit includes a cam 702 installed on the transmission shaft 617 and located on the inner side of the U-shaped frame plate 625. Guide annular grooves 703 arranged along the edges of the cam 702 are provided on both sides of the cam 702. The inner side of the guide annular groove 703 is slidably connected with a U-shaped bayonet 707 located above the cam 702. A third piston rod 708 is installed on the top of the U-shaped bayonet 707. A cavity 706 located above the guide groove 609 is provided on the inner side of the positioning column 5. A rectangular connecting bin 701 is provided on the positioning column 5 and is connected to one side of the cavity 706. A rectangular plug rod 704 is inserted into the interior of the rectangular connecting bin 701. A fixing plate 705 is installed at one end of the rectangular plug rod 704 away from the rectangular connecting bin 701. The top of the fixing plate 705 is connected to the bottom of the inner ring placement frame 3.

[0046] In this embodiment, when the fan-shaped guide wheel 604 rotates 90 degrees with the transmission shaft 617, the U-shaped bayonet 707 cannot be squeezed by the cam 702. When the rotation angle of the transmission shaft 617 exceeds 90 degrees, the protrusion of the cam 702 will be upward. At this time, the support bracket 610 cannot move. During this process, the cam 702 squeezes and guides the U-shaped bayonet 707 through the guide annular groove 703, so that the U-shaped bayonet 707 drives the third piston rod 708 to move upward, so that the aqueous solution inside the cavity 706 is squeezed by the third piston rod 708. Into the rectangular connecting bin 701, so that the rectangular plug rod 704 drives the fixed plate 705 to move in the direction away from the center of the positioning column 5, so that the inner ring placement frame 3 drives the inner ring of the bearing to move, so that the outer wall of the inner ring of the bearing can be fitted with the inner wall of the outer ring of the bearing. Similarly, when the telescopic cylinder 601 contracts, it will first drive the inner ring placement frame 3 to recover, so that the inner ring of the bearing first limits the steel balls that fall between the outer ring and the inner ring, and then diffuses the steel balls between the outer ring and the inner ring, further improving the stability of the steel balls moving between the inner ring and the outer ring.

[0047] Please refer to Figure 4 , Figure 6 A through hole having a diameter larger than the bottom diameter of the third piston rod 708 is provided at the center of the supporting frame 610 .

[0048] In this embodiment, this structure is provided to prevent the supporting link 610 from rubbing against the third piston rod 708 when moving, thereby increasing the service life of the third piston rod 708 and the supporting link 610 .
