Detailed implementation manners

[0028] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Such as Figure 1As shown in the figure, a bearing inner and outer ring assembling device includes an inner ring conveying mechanism for conveying the inner ring and an outer ring conveying mechanism for conveying the outer ring. A driving mechanism for driving the inner and outer rings of the bearing to move synchronously is provided between the inner ring conveying mechanism and the outer ring conveying mechanism. Both the inner ring conveying mechanism and the outer ring conveying mechanism include a conveying groove 1. The conveying groove 1 is in a right-angled shape arranged oppositely. The height of the conveying groove 1 of the inner ring conveying mechanism is less than the height of the conveying groove 1 of the outer ring conveying mechanism. The left end positions of the conveying grooves 1 overlap, and a jacking mechanism for jacking up the inner ring is provided at the overlapping position at the front end of the conveying groove 1. A pushing mechanism is provided at the front end of the conveying groove 1. The inner ring conveying mechanism and the outer ring conveying mechanism respectively support the inner and outer rings of the bearing, and drive the inner and outer rings of the bearing to move synchronously to the left in sequence through the driving mechanism. When the inner and outer rings of the bearing move to the leftmost end of the conveying groove 1, the pushing mechanism pushes the inner and outer rings of the bearing inward until the inner and outer rings overlap, and the jacking mechanism jacks up the inner ring and sleeves it on the outer ring, realizing the automatic assembly of the inner and outer rings of the bearing and improving the efficiency.

[0030] As Figure 2 shown, the driving mechanism includes a moving frame 3 that moves left and right, moving plates 4 provided on both sides of the moving frame 3, and a plurality of card slots 5 arranged side by side on the outer sides of the moving plates 4. The upper surface of the moving frame 3 is provided with planes of different heights. The two moving plates 4 move on the two planes respectively. The moving plates 4 are connected to the moving frame 3 through guide rails and sliders. When the moving frame 3 is at the rightmost end, the moving plates 4 are at the outermost sides. The card slots 5 catch the corresponding bearing raceway rings. Then the moving frame 3 moves to the left, and the card slots drive the raceway rings to move to the left. When the leftward movement is in place, the moving plates 4 retract, and the moving frame 3 moves to the right, moving back and forth, thereby realizing the sequential leftward movement of the inner and outer rings of the bearing.

[0031] As Figure 4 shown, the pushing mechanism includes a fixed frame 11 and push plates 12 provided on both sides of the fixed frame 11 and moving within the fixed frame 11. When the bearing raceway rings move to the leftmost end of the conveying groove 1, the push plates 12 on both sides move inward synchronously, pushing the inner and outer rings of the bearing to the middle position respectively and making the center lines of the inner and outer rings overlap.

[0032] As Figure 6As shown in the figure, the lifting mechanism includes a lifting cylinder 16, a positioning rod 17 arranged at the piston rod end of the lifting cylinder 16, and a lifting plate 18 arranged on the positioning rod 17. The lifting plate 18 is a circular plate, and the lifting plate 18 is flush with the conveying groove 1 of the inner ring conveying mechanism. The position of the lifting plate 18 corresponds to the position of the round hole on the conveying groove 1 of the inner ring conveying mechanism. A compression spring 19 is arranged on the positioning rod 17, and a baffle 20 is arranged below the positioning rod 17. The lower end of the compression spring 19 contacts the baffle 20, and the upper end of the compression spring 19 contacts the lifting plate 18. After the push plate pushes the inner ring of the bearing onto the lifting plate 18, the piston rod of the lifting cylinder 16 extends, and the positioning rod 17 and the lifting plate 18 rise synchronously, lifting the inner ring of the bearing. The inner ring of the bearing passes through the round hole 2 until the lifting plate 18 contacts the conveying groove 1 of the outer ring conveying mechanism. At this time, the inner ring of the bearing and the outer ring are on the same plane. Then, the piston rod of the compression spring 19 continues to extend, and the positioning rod 17 continues to rise against the elastic force of the compression spring 19 to realize the positioning of the inner ring of the bearing.

[0033] As Figure 4 shown, round holes 2 are arranged at the overlapping positions of the two conveying grooves 1. The diameter of the round hole is smaller than the outer diameter of the outer ring to prevent the outer ring from falling. The diameter of the round hole 2 in the lower conveying groove 1 is larger than the diameter of the lifting plate 18. The diameter of the round hole 2 in the lower conveying groove 1 is larger than the diameter of the round hole 2 in the upper conveying groove 1. The diameter of the lifting plate 18 is larger than the diameter of the inner ring of the bearing, ensuring that the inner ring of the bearing will not fall from the lifting plate 18, and the lifting plate 18 can pass through the round hole 2 in the lower conveying groove 1 and will not pass through the round hole 2 in the upper conveying groove 1.

[0034] As Figure 2 shown, a double-acting cylinder 6 is arranged at the middle position of the moving frame 3. The piston rods on both sides of the double-acting cylinder 6 are respectively connected to the corresponding moving plates 4. By the telescopic movement of the piston rods on both sides of the double-acting cylinder 6, the two moving plates 4 are driven to move synchronously in the same or opposite directions.

[0035] As Figure 3 shown, a bracket 7 is arranged between the two conveying grooves 1. The moving frame 3 is arranged on the bracket 7 and moves on the bracket 7. Guide rods are symmetrically arranged front and back on the bracket 7. Guide sleeves cooperating with the guide rods are arranged at the lower end of the moving frame 3. A motor 8 is arranged inside the bracket 7. A driving rod 9 is arranged inside the motor 8. A guide groove is arranged at the lower end of the moving frame 3. A guide rod 10 cooperating with the guide groove is arranged at the outer end of the driving rod 9. When the motor 8 drives the driving rod 9 to rotate, under the action of the guide rod 10 and the guide groove, the moving frame 3 continuously moves left and right on the bracket 7, and at the same time, in cooperation with the opening and retraction of the moving plates 4, the inner and outer rings of the bearing are sequentially conveyed to the left.

[0036] As Figure 4As shown in the figure, a pushing cylinder 13 for driving the movement of the push plate 12 on the same side is provided on the side surface of the fixing frame 11. A guiding rod is provided inside the fixing frame 11. Guiding sleeves that cooperate with the guiding rod are provided on both sides of the push plate 12. The movement of the push plate is guided by the guiding rod and the guiding sleeves. The cylinder end of the pushing cylinder 13 is fixed to the side surface of the fixing frame 11, and the piston rod end of the pushing cylinder 13 is connected to the corresponding push plate 12.

[0037] As Figure 5 shown in the figure, when one side of the push plate 12 moves, the push plate 12 on the other side moves synchronously in the same or opposite direction under the action of the connecting mechanism. The connecting mechanism includes a rotating rod 14 provided at the upper end of the fixing frame 11 and rotatably connected to the fixing frame 11 at the middle position, and connecting rods 15 provided at both ends of the rotating rod 14. The inner end of the connecting rod 15 is rotatably connected to the corresponding end of the rotating rod 14, and the outer end of the connecting rod 15 is rotatably connected to the corresponding push plate 12. When one side of the push plate 12 moves, the push plate 12 on the other side moves synchronously in the same or opposite direction under the action of the connecting rod 15 and the rotating rod 14.

[0038] As Figure 6 shown in the figure, a clamping groove 21 is provided on the outer cylindrical surface of the lifting plate 18, and the clamping groove 21 cooperates with the circular hole 2 of the upper conveying groove.

[0039] As Figure 4 shown in the figure, a limiting rod 22 for positioning the position of the outer ring of the bearing is provided at one inner end of the upper conveying groove 1.
