Description

Technical Field

[0001] The utility model relates to the technical field of bearing production, in particular to an inner and outer ring sleeve device for bearing production. Background Art

[0002] A bearing is a precision mechanical component that converts the sliding friction between a rotating shaft and a shaft seat into rolling friction, thereby reducing friction losses. A bearing is generally composed of four parts: an inner ring, an outer ring, rolling elements, and a cage. The function of the inner ring is to cooperate with the shaft and rotate with the shaft; the function of the outer ring is to cooperate with the bearing seat to provide support. When producing bearings, the first step is to fit the inner and outer rings of the bearing together.

[0003] The scattered inner and outer rings of the bearing can be neatly arranged and transported, and then the inner and outer rings of the bearing can be grabbed and moved together by mechanical equipment, and then placed on a conveyor belt and transported to the next process. However, there are some problems in its use. For general equipment, the inner and outer rings of the bearing need to be moved to the specified positions respectively by different mechanical equipment, and then the inner ring of the bearing is pushed from the bottom to the top so that it is inside the outer ring of the bearing, and then the inner and outer rings of the bearing are pushed as a whole, and the operation steps are complicated.

The unloading mechanism includes a limit block 7, a movable shaft 8, a lever 9, a movable groove 10, a fixed block 11 and a fixed block 2 12, wherein the limit block 7 is fixed to the side wall of the second discharge trough 5, a through hole is provided on the top of the limit block 7, and a movable shaft 8 is installed in the through hole, and four groups of equidistant levers 9 are fixed to the outer wall of the movable shaft 8, and a movable groove 10 is provided on the outer wall of the second discharge trough 5 at a position corresponding to the horizontal height of the lever 9, and four groups of fixed blocks 11 are fixed to one end of the bottom of the movable groove 10, and a fixed block 2 12 is fixed to the side position of the U-shaped groove 3 on the surface of the turntable 2. When the turntable 2 drives the outer shaft ring 18 to rotate, the fixed block 2 12 on the surface of the turntable 2 can push the fixed block 11 to rotate as it rotates. When the fixed block 11 rotates, the movable shaft 8 drives the lever 9 to rotate together. The lever 9 passes through the movable groove 10 and pushes the inner shaft ring 19 to move through the side wall, so that the inner shaft ring 19 enters the discharge port 16 and falls into the outer shaft ring 18 in the U-shaped groove 3 from the discharge port 6. The side of each group of U-shaped grooves 3 is provided with a fixed block 2 12, so when the U-shaped groove 3 drives the outer shaft ring 18 to move to the bottom of the discharge port 6, the fixed block 2 12 can just push the fixed block 11 to rotate, so that the inner shaft ring 19 falls into the outer shaft ring 18, and the lever 9 blocks the subsequent inner shaft rings 19 while pushing the inner shaft ring 19 to prevent the inner shaft rings 19 from falling out of the discharge port 6 continuously.

[0028] A discharge trough 13 is provided on one side of the support plate 1, and the discharge trough 13 is located at the lower position of the second discharge trough 5. A second discharge port 14 is provided on the surface of the support plate 1 at a position corresponding to the discharge trough 13. When the turntable 2 moves the assembled outer shaft ring 18 and the inner shaft ring 19 to the second discharge port 14 through the U-shaped groove 3, the outer shaft ring 18 and the inner shaft ring 19 can pass through the second discharge port 14. A conveyor belt is provided below the discharge trough 13 to transport the assembled inner and outer shaft rings to the next process. A guide block 15 is fixed on the surface of the support plate 1 near the second discharge port 14. The guide block 15 is triangular in shape and extends outside the inclined support plate 1. A mounting groove 16 is provided in the middle of the turntable 2, and a slide groove 17 is provided at the bottom of the mounting groove 16 corresponding to the position of the support rod of the guide block 15. When the turntable 2 rotates, the support rod of the guide block 15 remains stationary in the slide groove 17, and the guide block 15 remains stationary in the mounting groove 16. When the U-shaped groove 3 moves the sleeved inner and outer shaft rings to the front of the discharge port 14, the side wall of the outer shaft ring 18 contacts the inclined surface of the guide block 15, so that the outer shaft ring 18 moves along the inclined surface of the guide block 15 when moving. The sleeved outer shaft ring 18 and the inner shaft ring 19 can be moved into the discharge trough 13 through the inclined surface of the guide block 15, ensuring that the completed sleeved outer shaft ring 18 and the inner shaft ring 19 are sent to the next program to prevent the shaft ring from continuing to rotate with the U-shaped groove 3.

[0029] Working principle: the outer shaft ring 18 is arranged and transported to the turntable 2 through the first discharge groove 4, and the inner shaft ring 19 is arranged and transported to the turntable 2 through the second discharge groove 5. When the outer shaft ring 18 enters the surface of the turntable 2, it is stuck in the U-shaped groove 3. As the turntable 2 rotates, it approaches the direction of the inner shaft ring 19. When the turntable 2 rotates, the fixed block 2 12 fixed on the surface of the turntable 2 pushes the fixed block 11 at the bottom of the movable shaft 8 to move, so that the fixed block 11 drives the movable shaft 8 to rotate. When the movable shaft 8 rotates, the lever 9 slides through the movable groove 10, and pushes the inner shaft ring 19 in the second discharge groove 5 to the lower material port 6. The inner shaft ring 19 falls into the U-shaped groove 3 through the lower material port 6, and then falls into the U-shaped groove 3. The outer shaft ring 18 and the inner shaft ring 19 are sleeved in the outer shaft ring 18, and the lever 9 is moved by the fixed block 12, and the fixed block 12 is arranged on the side of each U-shaped groove 3, so when the U-shaped groove 3 passes the discharge port 16, the lever 9 will push the inner shaft ring 19 to fall into the U-shaped groove 3 to ensure the matching of the outer shaft ring 18 and the inner shaft ring 19. The assembled inner and outer rings continue to be moved by the U-shaped groove 3. During the movement, the side wall of the outer shaft ring 18 fits the guide block 15, and the outer shaft ring 18 moves along the inclined surface of the guide block 15, so that the inner and outer rings gradually approach the discharge trough 13, and a conveyor belt is arranged below the discharge trough 13. When the inner and outer rings move to the discharge trough 13, they move to the next processing equipment through the transmission belt.
