A feeding mechanism 7 for conveying rollers and cages is installed on the top of the roller press-fitting mechanism 3. A steering mechanism 9 for changing the falling direction of the rollers is rotatably installed in the middle of the feeding mechanism 7. A horizontally arranged roller feeding cylinder 6 is fixedly installed on the side of the feeding mechanism 7, and a cage conveying mechanism 10 is arranged at the top of the feeding mechanism 7. A press-fitting cylinder 11 inclined at 45° is fixedly installed at the end of the roller press-fitting mechanism 3.

[0033] As a further solution in the present invention, the bearing rotating tray 14 includes an annular housing 141. A outer ring positioning ring 142 is fixedly installed on the top of the annular housing 141. A plurality of elastic pressing members 143 are arranged on the inner wall of the outer ring positioning ring 142. And the bearing outer ring 17 is inserted into the inside of the outer ring positioning ring 142. In the present invention, the bearing outer ring 17 is inserted into the inside of the outer ring positioning ring 142, and relies on a plurality of elastic pressing members 143 distributed in an annular array to hold the bearing outer ring 17, and is conducive to the thrust of the elastic pressing members 143 synchronously towards the center of the circle, so as to keep the bearing outer ring 17 and the bearing inner ring 18 coaxially installed.

[0034] As a further solution in the present invention, the inner ring positioning mechanism 12 includes a bakelite centering core 121 located in the middle. And a guiding groove 122 adapted to the roller pressing mechanism 3 is arranged on the side of the bakelite centering core 121. Fixed fasteners 123 connected by springs are arranged at both ends of the bakelite centering core 121. The bearing inner ring 18 is sleeved outside the bakelite centering core 121. A ball loading port 19 in a fan-shaped structure is arranged on the top of the bearing inner ring 18. And a ball filling block 20 is installed at the upper end of the ball loading port 19 by bolts. In the present invention, the bearing inner ring 18 is fixedly installed outside the bakelite centering core 121. The bearing outer ring 17 and the bearing inner ring 18 are engaged to form a bearing raceway with a cross-section of two 90° angle cones. And the ball loading port 19 on the bearing inner ring 18 faces the position of the guiding groove 122. When the roller pressing mechanism 3 descends, the bottom end thereof is inserted into the guiding groove 122 to complete the positioning operation of the roller pressing mechanism 3 and the ball loading port 19.

[0035] As a further solution in the present invention, the feeding mechanism 7 includes a bushing 71. And an inverted T-shaped roller feeding channel 72 is arranged inside the bushing 71. Inductive switches for controlling the feeding cylinder 6 are arranged in both the vertical section and the horizontal section of the roller feeding channel 72. A roller conveying pipe 8 is inserted into the top of the roller feeding channel 72. An outlet square hole 73 connecting the steering mechanism 9 and the roller pressing mechanism 3 is arranged at the bottom of the bushing 71. A feeding slider 16 connected to the front end of the feeding cylinder 6 is slidably installed in the horizontal section of the roller feeding channel 72. In the present invention, at the beginning of the cycle, the rollers fall into the roller feeding channel 72 from the roller conveying pipe 8 under the air flow transportation. The rollers trigger the inductive switches, and the feeding cylinder 6 horizontally pushes the rollers along the horizontal section of the roller feeding channel 72 into the steering mechanism 9. When two rollers are pushed in, the inductive switch in the horizontal section is triggered, and the feeding cylinder 6 will reset and stop. The second roller will push the first roller to the corner of two holes of the steering mechanism 9. The first roller freely falls from the round hole in a vertical posture into the outlet square hole 73 and then enters the roller pressing mechanism 3. When the first roller triggers the inductive switch at the entrance of the roller pressing mechanism 3, the steering mechanism 9 rotates counterclockwise by 90°. The second roller changes from a vertical posture to a horizontal posture and freely falls into the outlet square hole 73 and then enters the roller pressing mechanism 3.

[0036] As a further solution in the present invention, the steering mechanism 9 includes a rotating table 91 rotatably connected to the bushing 71, and a rotating table drive motor installed outside the bushing 71. A horizontal square hole 92 is provided on the side surface of the rotating table 91, and the square hole 92 is aligned with the roller feeding channel 72. A vertical round hole 93 is provided at the bottom of the rotating table 91, and the round hole 93 is aligned with the discharging square hole 73. The square hole 92 and the round hole 93 communicate with each other at a 90° angle. In the present invention, two rollers are both pushed into the square hole 92, and the second roller will push the first roller to the connecting corner of the square hole 92 and the round hole 93. The first roller freely falls into the discharging square hole 73 from the round hole 93 in a vertical posture, and then enters the roller pressing mechanism 3; the first roller triggers an induction switch at the entrance of the roller pressing mechanism 3, and the rotating table 91 rotates counterclockwise by 90°. The second roller changes from a vertical posture to a horizontal posture and freely falls into the discharging square hole 73, and then enters the roller pressing mechanism 3, completing the cross-feeding operation of the two rollers.

[0037] As a further solution in the present invention, a chute 74 adapted to the cage conveying mechanism 10 is provided at the top of the bushing 71, and a cage slideway 75 connecting the cage conveying mechanism 10 and the roller pressing mechanism 3 is provided at the bottom of the chute 74. In the present invention, two types of cage retainers in different directions are loaded in the cage conveying mechanism 10. By the reciprocating movement of the cage conveying mechanism 10 inside the chute 74, the two types of cage retainers are alternately made to fall into the roller pressing mechanism 3 in sequence, and the cage retainers and the rollers alternately fall into the bearing raceway.

[0038] As a further solution in the present invention, the cage conveying mechanism 10 includes an adjusting cylinder 101 installed on the bushing 71, and a movable seat 102 slidably installed inside the chute 74. The output end of the adjusting cylinder 101 is connected to the end of the movable seat 102. Two cage discharging holes 103 are provided in the middle of the movable seat 102, and cage conveying pipes 104 are inserted at the tops of the two cage discharging holes 103. In the present invention, the cage retainers in two directions are sequentially conveyed to the movable seat 102 through the cage conveying pipes 104. By the reciprocating movement of the movable seat 102 inside the chute 74, the cage discharging holes 103 and the cage slideway 75 are alternately overlapped, so as to alternately convey the cage retainers and the cross rollers to the bearing raceway, completing the loading operation of the rollers.

[0039] As a further solution in the present invention, the roller pressing mechanism 3 includes a pressing housing 31 with an L-shaped structure. A pressing part 32 corresponding to the ball filling port 19 is provided at the bottom of the pressing housing 31. Inside the pressing housing 31, a roller pressing groove 33, a cage pressing groove 34, and a roller pressing component 35 are sequentially arranged. The outlets of the roller pressing groove 33, the cage pressing groove 34, and the roller pressing component 35 are all arranged at the pressing part 32. In the present invention, during the filling operation, the roller pressing component 35 is in an extended state. The bottom end of the roller pressing component 35 is inserted into the bearing raceway. The rollers fall from the roller pressing groove 33 into the bearing raceway, and the cage of the corresponding direction falls from the cage pressing groove 34 into the bearing raceway. At this time, there is a gap between the rollers and the cage. After pressing in one roller and the cage, the bearing rotating tray 14 drives the bearing outer ring 17 to rotate clockwise by a certain angle first. The cage touches the roller pressing component 35 and thus converges towards the rollers, so that a negative clearance is formed between the rollers and the cage. Then the bearing rotating tray 14 drives the bearing outer ring 17 to rotate counterclockwise by a certain angle. The cage and the rollers pass through the ball filling port, making way for the next roller to be pressed in. The counting of the number of pressed rollers can be changed according to the requirements of the finished bearing.

[0040] As a further solution in the present invention, the roller pressing groove 33 has an L-shaped structure, and a roller pressing block 15 connected to the pressing cylinder 11 is slidably installed at the corner of the roller pressing groove 33. An induction switch for controlling the pressing cylinder 11 is provided at the corner of the roller pressing groove 33. In the present invention, the upper end of the roller pressing groove 33 is an inlet channel for arranging the rollers falling from the roller turning mechanism. The lower end of the roller pressing groove 33 is a pressing channel. The pressing channel intersects the inlet channel at 90°. An induction switch for controlling the pressing cylinder 11 is provided at the intersection position. The end interface of the pressing channel is connected to the ball filling port to ensure that the rollers smoothly enter the bearing raceway, and the pressing cylinder 11 presses the rollers into the bearing ball filling port.

[0041] As a further solution in the present invention, the roller pressing component 35 includes a pressing groove 352 provided on the side of the pressing housing 31. A U-shaped movable pressing block 353 is slidably installed inside the pressing groove 352. An insertion end 354 is provided at the bottom end of the movable pressing block 353. The roller pressing component 35 further includes a pressing cylinder 351 for driving the movement of the movable pressing block 353. The pressing cylinder 351 is installed on the pressing housing 31. In the present invention, during the roller pressing operation, the movable pressing block 353 moves outwards, and the insertion end 354 extends into the bearing raceway to form a baffle structure to fix the bearing inner ring 18. When the rollers and the cage are filled, the bearing outer ring 17 is rotated, which is beneficial for the insertion end 354 to block the newly filled cage and rollers, and circumferentially press the cage and the rollers.

[0042] In use, at the beginning of the cycle, the rollers fall from the roller conveying pipe 8 into the roller loading channel 72 under the air flow conveyance. The rollers trigger the induction switch, and the loading cylinder 6 horizontally pushes the rollers along the horizontal section of the roller loading channel 72 into the steering mechanism 9. When two rollers are pushed in, the induction switch on the horizontal section is triggered, and the loading cylinder 6 will reset and stop. The second roller will push the first roller to the corner of the two holes of the steering mechanism 9. The first roller freely falls from the round hole in a vertical posture into the discharge square hole 73 and then enters the roller pressing mechanism 3. The first roller triggers the induction switch at the entrance of the roller pressing mechanism 3, and the steering mechanism 9 rotates counterclockwise by 90°. The second roller changes from a vertical posture to a horizontal posture and freely falls into the discharge square hole 73, and then enters the roller pressing mechanism 3. The roller cage conveying mechanism 10 is loaded with roller cages in two directions. The cages in the two directions are sequentially conveyed to the movable seat 102 through the cage conveying pipe 104. Through the reciprocating movement of the movable seat 102 inside the chute 74, the cage discharging hole 103 and the cage slideway 75 are alternately overlapped, and the cages and the crossed rollers are alternately conveyed into the bearing raceway. During the loading operation, the roller pressing assembly 35 is in the extended state. The bottom end of the roller pressing assembly 35 is inserted into the bearing raceway. The rollers fall from the roller pressing groove 33 into the bearing raceway. The roller cages in the corresponding direction fall from the cage pressing groove 34 into the bearing raceway. At this time, there is a gap between the rollers and the cages. After pressing in one roller and one cage, the bearing rotating tray 14 drives the bearing outer ring 17 to rotate clockwise by a certain angle first. The cage touches the roller pressing assembly 35 and thus converges towards the rollers, so that a negative clearance is formed between the rollers and the cages. The bearing rotating tray 14 drives the bearing outer ring 17 to rotate counterclockwise by a certain angle again. The cage and the rollers pass through the ball filling port, making way for the next roller to be pressed in. The number of pressed-in rollers is counted. A certain number of rollers are arranged crosswise one by one and loaded into the raceway. Finally, the ball filling block 20 is installed and adjusted, and the operation of loading the rollers is completed.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
