DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The present utility model will be further described below by way of examples, but the present utility model is not limited to the scope of the described examples.

[0029] As Figures 1-5 shown, the double-loop feeding mechanism for the inner surface of a bearing ring grinding machine described above includes:

[0030] The silo 1 has an inclined bottom structure, one side of the silo 1 is rotatably connected to a lifting assembly, the lifting assembly is connected to a connecting plate 19 through a transmission assembly, the connecting plate 19 is fixedly connected to one end of a rotating rod 20, the rotating rod 20 is rotatably connected to the top of the silo 1, and the other end of the rotating rod 20 is fixedly connected to a baffle 21;

[0031] The guide rail 2 is fixedly installed to the top of one side of the silo 1, and the guide rail 2 extends to the inside of the silo 1 in an inclined state. A limiting component is fixedly installed at the bottom of the guide rail 2. The surface of the guide rail 2 is fixedly connected to the flange 3, and the surface of the flange 3 is fixedly connected with a guide block 4, and the guide block 4 is correspondingly arranged above the silo 1.

[0032] In the present technical solution, the lifting assembly includes a rotating drum 11, which is rotatably connected to the bottom of the silo 1. A gap for storing bearing rings is formed between the bottom of the silo 1 and the rotating drum 11. A plurality of evenly distributed magnets 12 are fixedly connected to the surface of the rotating drum 11, and the rotating drum 11 is correspondingly arranged on one side of the guide rail 2. When the rotating drum 11 rotates, the bearing rings inside the silo 1 are adsorbed by the magnets 12, and the rotating drum 11 rotates to achieve lifting, so that it rotates above the guide rail 2.

[0033] In the present technical solution, an arc-shaped guide plate 22 is fixedly installed inside the silo 1. The guide plate 22 is correspondingly arranged above the rotating drum 11, and the top of the guide plate 22 is located above the guide rail 2. The bearing ring rotating with the rotating drum 11 contacts the guide plate 22, and moves toward the side of the guide rail 2 during the rotation of the bearing ring, and forces it to separate from the magnet 12. At this time, it is no longer subject to adsorption force and falls exactly onto the surface of the convex edge 3, and part of the bearing ring falls into the inside of the guide rail 2. The inclined guide rail 2 can achieve slow transportation.

[0034] In the present technical solution, one end of the rotating drum 11 is coaxially fixedly connected to the transmission assembly, and the transmission assembly is located outside the silo 1. The transmission assembly is composed of a turntable 14. The edge of the turntable 14 is rotatably connected to the rotating rod 17, and the rotating rod 17 is movably connected to the connecting plate 19 through a connecting member 18. When the rotating drum 11 rotates, it drives the turntable 14 to rotate synchronously. The turntable 14 drives the rotating rod 17 to rotate and swing continuously, and drives the connecting plate 19 to move through the connecting member 18.

[0035] In the present technical solution, a variable frequency motor 15 is fixedly mounted on the outer wall of the silo 1, the output end of the variable frequency motor 15 and one end of the turntable 14 are fixedly connected to the pulley 13, and the two pulleys 13 are connected by a belt 16. The cooperation of the belt 16 and the pulley 13 enables the variable frequency motor 15 to drive the rotating drum 11 and the turntable 14 to rotate synchronously.

[0036] In this technical solution, the number of the rotating rods 20 is two and they are symmetrically distributed on both sides of the silo 1. The rotating rods 20 are in a bent structure, and a connecting plate 19 and a baffle 21 are respectively arranged between the two ends of the two rotating rods 20. When the connecting plate 19 moves, it drives the rotating rods 20 to rotate on both sides of the silo 1, thereby driving the baffle 21 to swing continuously. When the baffle 21 contacts the surface of the guide rail 2, at this time, the baffle 21 also contacts the driven rod 7, causing it to drive the top block 8 to contact the bearing race located inside the opening 6, lift it up and then continue to roll downward, and contact the baffle 21. When the baffle 21 is lifted, it separates from the driven rod 7, and the top block 8 moves out of the opening 6. The second bearing race falls into the opening 6 to limit the subsequent bearing races, while the first bearing race separates from the baffle 21 and continues to feed. That is, by rotating the turntable 14 one circle, the rotating rod 20 is controlled to swing once, thereby realizing the conveying of one bearing race. By adjusting the output power of the frequency conversion motor 15, the feeding interval can be controlled.

[0037] In this technical solution, the cross-section of the guide rail 2 is a U-shaped structure. Convex edges 3 extending into the interior of the silo 1 are provided on both sides of the guide rail 2. The convex edges 3 are used for the conveying of horizontally distributed bearing races, and the vertically distributed bearing races are conveyed by rolling inside the guide rail 2.

[0038] In this technical solution, the limiting assembly includes a driven rod 7. The driven rod 7 is in a bent structure and is rotatably connected to the bottom of the guide rail 2. The driven rods 7 are symmetrically distributed outside both sides of the guide rail 2. The two ends of the two driven rods 7 are respectively fixedly connected to both sides of the top block 8. An opening 6 is provided at the bottom of the guide rail 2, and the top block 8 is correspondingly arranged below the opening 6. The opening 6 is located on the lower oblique side of the baffle 21. When the baffle 21 fits the surface of the guide rail 2, both ends of the baffle 21 contact the bent parts of the driven rods 7. The driven rods 7 can rotate around both sides of the guide rail 2 and drive the top block 8 to move to lift the bearing race.

[0039] In this technical solution, the number of the guide blocks 4 is two and they are respectively located on both sides of the guide rail 2. The two guide blocks 4 are staggeredly distributed and are both provided with inclined edges for guiding the bearing race. The guide blocks 4 are used to guide the bearing race on the surface of the convex edge 3 so that the horizontally distributed bearing race falls back into the interior of the silo 1.

[0040] In this technical solution, the edge of the silo 1 is fixedly connected to the guide rail 2 through a retaining wall 9. Feeding ports 10 are provided at the top of the silo 1 on both sides of the guide rail 2. The bearing races are added through the feeding ports 10. The setting of the retaining wall 9 can prevent the bearing races on the convex edge 3 from falling.

[0041] The present utility model is not limited to the above embodiments. No matter what changes are made in its shape or structure, they all fall within the protection scope of the present utility model. The protection scope of the present utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principle and essence of the present utility model, but these changes and modifications all fall within the protection scope of the present utility model.
