A positioning frame is installed on the inner wall of the conveyor shaft, located on the left side. The right end of the conveyor shaft is rotatably mounted to the left side of the positioning frame via a bearing. A feeding rod is rotatably mounted on the right end of the bottom support rod via a bearing. The feeding rod is fixedly mounted to the inner wall of the feed inlet, with ball bearings positioned above the bottom support rod. A screw hole is provided on the outer wall near the bottom of the conveyor shaft, and a first limiting rod is installed inside the screw hole via a thread. A first screening port is installed on the front side wall of the outer frame, located in front of the first limiting rod. A second screening port is installed to the left of the first screening port. A third screening port is installed on the front side wall of the outer frame to the left of the second screening port. A second limiting rod is installed on the outer wall of the conveying shaft to the rear of the second screening port. A third limiting rod is installed on the outer wall of the conveying shaft to the rear of the third screening port.

[0011] Preferably, the outer wall of the conveying shaft has a plurality of screw holes.

[0012] Compared with the prior art, this utility model provides a ball conveying device for bearing processing, which has the following advantages:

[0013] 1. This ball bearing conveying device, during conveying, allows smaller diameter steel balls that do not meet the required dimensions to fall directly downwards between the two bottom support rods when they land above the rods, thus removing the smaller steel balls. Then, the conveying shaft drives the conveying pusher to rotate, pushing the steel balls to the left. Simultaneously, the conveying shaft drives the first limiting rod to rotate, preventing oversized steel balls from passing through the gap between the first limiting rod and the conveying pusher. These oversized steel balls are then pushed forward by the cooperation of the first limiting rod and the conveying pusher, thus removing the larger-diameter steel balls that meet the required dimensions. Screening is completed during the conveying process, eliminating the need for a separate screening step.

[0014] 2. This ball bearing conveying device for bearing processing can adjust the size of the bearings during screening by adjusting the installation positions of the first, second, and third limit rods and the lateral distance between each rod and the surface of the conveying push plate on its right. This allows for the screening of multiple sizes in one operation, improving screening efficiency and effectiveness. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a ball bearing conveying device for bearing processing, including an outer frame 1. A power motor 2 is installed on the left side wall of the outer frame 1. A conveying gear 3 is installed on the left side wall of the outer frame 1 at a position slightly above the center. A transmission gear is installed at the output end of the power motor 2, and the transmission gear meshes with the conveying gear 3. A meshing gear 6 is installed on the left side wall of the outer frame 1 at a position slightly below the front of the conveying gear 3, and the conveying gear 3 meshes with the meshing gear 6. A conveying shaft is rotatably mounted on the left inner wall of the outer frame 1 via a bearing. 4. The left end of the conveying shaft 4 passes through the outer frame 1 and is installed on the right side wall of the conveying gear 3. A conveying pusher 5 is installed on the outer wall of the conveying shaft 4. A bottom support rod 7 is rotatably installed on the left side wall of the outer frame 1, directly opposite the meshing gear 6, via a bearing. The left end of the bottom support rod 7 passes through the outer frame 1 and is installed on the right side wall of the meshing gear 6. The right end of the bottom support rod 7 is installed on the right inner wall of the outer frame 1 via a bearing. A feed inlet 8 is opened on the right side wall of the outer frame 1. A positioning frame is installed on the inner wall of the feed inlet 8, located on the left side. 9. The right end of the conveying shaft 4 is rotatably mounted to the left side of the positioning frame 9 via a bearing. The right end of the bottom support rod 7 is rotatably mounted with a feeding rod 10 via a bearing. The feeding rod 10 is fixedly mounted to the inner wall of the feed inlet 8. The ball bearing 11 is locked above the bottom support rod 7. A screw hole is opened on the outer wall near the bottom of the conveying shaft 4. A first limiting rod 12 is installed inside the screw hole via a thread. A first screening port 13 is installed on the front side wall of the outer frame 1, located in front of the first limiting rod 12. The left side of the first screening port 13 is located on the front side wall of the outer frame 1. A second screening port 15 is installed at a certain position. A third screening port 17 is installed on the front side wall of the outer frame 1 at a position to the left of the second screening port 15. A second limiting rod 14 is installed on the outer wall of the conveying shaft 4 at a position to the rear of the second screening port 15. A third limiting rod 16 is installed on the outer wall of the conveying shaft 4 at a position to the rear of the third screening port 17. A discharge port 19 is installed on the front side wall of the outer frame 1 at a position to the left. A discharge push plate 18 is installed on the outer wall of the conveying shaft 4 at a position close to the left end of the conveying push plate 5.

[0021] Furthermore, there are two bottom support rods 7. The second bottom support rod 7 is installed on the right side of the transmission gear at the output end of the power motor 2. During conveying, when a steel ball with a smaller diameter that does not meet the size requirements falls above the two bottom support rods 7, it will fall directly downwards between the two bottom support rods 7, thereby removing the smaller steel ball that does not meet the size requirements.

[0022] Furthermore, the right end of the bottom support rod 7 is lower than the left end, and the conveying shaft 4 is parallel to the bottom support rod 7, so that when the ball is above the bottom support rod 7, it will roll to the right and stick to the left side surface of the conveying push plate 5, and then the ball is screened by the first limiting rod 12 and the bottom support rod 7.

[0023] Furthermore, the lateral distance between the third limiting rod 16, the second limiting rod 14, and the first limiting rod 12 and the surface of their respective right-side conveying push plate 5 gradually increases. As the conveying shaft 4 drives the conveying push plate 5 to rotate and push the steel ball to the left, the conveying shaft 4 drives the first limiting rod 12 to rotate. Steel balls that are too large cannot pass through the gap between the first limiting rod 12 and the conveying push plate 5, and are thus pushed forward by the cooperation of the first limiting rod 12 and the conveying push plate 5, thereby removing steel balls that are too large in diameter and meet the size requirements. The screening is completed during the conveying process, and no separate screening process is required.

[0024] Furthermore, the distance between the two bottom support rods 7 is less than the pitch of the conveying push plate 5, the balls are supported by the two bottom support rods 7, and the balls can pass through the gap of the conveying push plate 5.

[0025] Furthermore, there are several screw holes on the outer wall of the conveying shaft 4. By adjusting the installation positions of the first limiting rod 12, the second limiting rod 14 and the third limiting rod 16, and adjusting the lateral distance between each of them and the surface of the right-side conveying push plate 5, the size of the screening can be adjusted. This allows for the completion of screening and selection of multiple sizes at once, improving screening efficiency and screening effect.

[0026] During use, the balls roll to the left along the feeding rod 10 to above the bottom support rod 7. The power motor 2 drives the conveying gear 3 to rotate via the transmission gear, which in turn drives the meshing gear 6 to rotate. The transmission gear and meshing gear 6 then drive the two bottom support rods 7 to rotate, causing the balls to roll forward and backward above the two bottom support rods 7. Balls with too small a diameter will fall directly downwards through the gap between the two bottom support rods 7 and be screened out. Simultaneously, the conveying gear 3 drives the conveying shaft 4 to rotate, which in turn drives the conveying pusher 5 to rotate. The conveying pusher 5 pushes the balls to the left along the bottom support rods 7. When the balls reach the right side of the first limit rod 12, they are pressed tightly against the left side of the conveying pusher 5. If the diameter of the balls is larger than the first limit rod... The minimum distance between the first limit rod 12 and the left side surface of the conveying push plate 5 is such that the ball will simultaneously contact the left side surface of the conveying push plate 5 and the surface of the first limit rod 12. The ball is pushed forward by the conveying push plate 5 and the first limit rod 12, causing the ball to flip into the interior of the first screening port 13 and be discharged forward. The ball continues to move to the left by the first limit rod 12. Similarly, the ball is screened by the second limit rod 14 and the third limit rod 16. The screened ball rolls forward through the second screening port 15 and the third screening port 17. After triple screening, the conveying push plate 5 rotates and pushes the ball to the leftmost position. The conveying shaft 4 drives the unloading push plate 18 to rotate and push the ball forward, pushing the qualified ball into the unloading port 19 and discharging it forward.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
