[0029] like Figure 1As shown, a bearing inner and outer ring assembly device comprises 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 arranged between the inner ring conveying mechanism and the outer ring conveying mechanism, the inner ring conveying mechanism and the outer ring conveying mechanism both comprise a conveying trough 1, the conveying trough 1 is a right-angle shape arranged relatively, the height of the conveying trough 1 of the inner ring conveying mechanism is less than the height of the conveying trough 1 of the outer ring conveying mechanism, the left end position of the conveying trough 1 is an overlapping position, the front end position of the conveying trough 1 is provided with a lifting mechanism for lifting the inner ring, and the front end of the conveying trough 1 is provided with a pushing mechanism; 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 trough 1, the pushing mechanism pushes the inner and outer rings of the bearing inward until the inner and outer rings of the bearing overlap, and the lifting mechanism lifts the inner ring and sleeves it in the outer ring, thereby realizing the automatic assembly of the inner and outer rings of the bearing and improving the efficiency.

[0030] like Figure 2 As shown, the driving mechanism includes a moving frame 3 that moves left and right, a moving plate 4 arranged on both sides of the moving frame 3, and a plurality of slots 5 arranged in parallel on the outside of the moving plate 4. The upper surface of the moving frame 3 is provided with planes of different heights, and the two moving plates 4 move on two planes respectively. The moving plate 4 and the moving frame 3 are connected by a guide rail slider. When the moving frame 3 is located at the rightmost end, the moving plate 4 is located at the outermost side, and the slot 5 clamps the corresponding bearing raceway ring. Then the moving frame 3 moves to the left, and the slot drives the raceway ring to move to the left, and moves to the left to the position axis. The moving plate 4 is retracted, and the moving frame 3 moves to the right, and moves back and forth, thereby realizing the leftward movement of the inner and outer rings of the bearing in sequence.

[0031] like Figure 4 As shown, the pushing mechanism includes a fixed frame 11, and push plates 12 arranged on both sides of the fixed frame 11 and moving inside the fixed frame 11. When the bearing raceway ring moves 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.
