[0002] In existing technologies, precision machining of bearing rings using a grinding machine is an essential process. To achieve automated feeding of bearing rings, most manufacturers use vibratory feeders. However, for bearing rings with similar diameters and heights but smaller dimensions, the existing vibratory feeder method cannot be used for automated feeding, requiring manual feeding. Due to their small size, manual feeding is slow and results in low production efficiency. Summary of the Invention

[0003] The purpose of this utility model is to provide an automatic leveling and feeding device for grinding machines, which can solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: An automatic leveling and feeding device for a grinding machine includes a feeding vibratory plate.

A feeding channel is formed inside the flexible threaded tube. The head of the flexible threaded tube is vertically positioned below the end of the feeding track. A curved feeding rod is provided between the head of the flexible threaded tube and the end of the feeding track. One end of the curved feeding rod extends into the feeding track, and the other end extends into the head of the flexible threaded tube. The tail of the flexible threaded tube has a discharge port opposite to the feed port of the grinding machine. The threaded feeding tube is driven to rotate by a drive mechanism.

[0005] Preferably, the tail end of the flexible threaded tube is inserted into a rotating shaft and rotates with the rotating shaft.

[0012] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0013] like Figure 1 , Figure 2 As shown, this utility model provides an automatic leveling and feeding device for a grinding machine, including a feeding vibratory plate 1. The feeding vibratory plate 1 is provided with a spirally rising feeding track 2. The end of the feeding track 2 is provided with a leveling track 3. The inner wall of the leveling track 3 is U-shaped. The end of the leveling track 3 is provided with a feeding track 4. The end of the feeding track 4 extends out of the feeding vibratory plate 1. A flexible threaded tube 5 is provided on the outside of the feeding vibratory plate 1. A feeding channel is formed inside the flexible threaded tube 5. The head of the flexible threaded tube 5 is vertically located below the end of the feeding track 4. A curved feeding rod 6 is provided between the head of the flexible threaded tube 5 and the end of the feeding track 4. One end of the curved feeding rod 6 extends into the feeding track 4, and the other end extends into the head of the flexible threaded tube 5. The tail of the flexible threaded tube 6 is provided with a discharge port and is opposite to the feed port of the grinding machine. The threaded feeding tube 6 is driven by a drive mechanism to rotate.

[0014] In use, a large batch of bearing rings are placed into the feeding vibratory feeder 1. The vibratory feeder 1 vibrates, causing the bearing rings to spiral upward along the feeding track 2. The feeding track 2 does not screen the bearing rings. When the bearing rings reach the leveling track 3, because the leveling track 3 is U-shaped, the bearing rings can only lie down in the leveling track 3 and be conveyed forward one by one. This is because upright bearing rings cannot stand upright in the U-shaped leveling track 3 and must lie down, otherwise they will fall out of the leveling track 3. The leveling track 3 achieves leveling and screening of the bearing rings. Then the bearing rings are conveyed to the feeding track 4. Because the bearing rings lie in the feeding track 4, they are strung on one end of the curved feeding rod 6 during forward conveying. Then they move along the curved feeding rod 6 and fall into the flexible threaded tube 5. Because the flexible threaded tube 5 is set perpendicular to the feeding track 4, and the curved feeding rod 6 is curved... The curved shape of the curved feeding rod 6 allows its middle section to rest on the edge of the feeding track 4 when there are no bearing rings on it. The upper end of the curved feeding rod 6 is slightly upturned, while the lower end rests against the upper inner wall of the flexible threaded tube 5. Furthermore, the relatively small diameter of the curved feeding rod 6 makes it easy for the bearing rings conveyed from the feeding track 4 to be fed onto it. Then, the bearing rings in front are pushed onto the curved feeding rod 6 one by one by the bearing rings behind them. Because the height and diameter of the bearing rings are similar, and the curved feeding rod 6 is thin and has a certain curvature, it does not hinder the movement of the bearing rings on the curved feeding rod 6. Then, the flexible threaded tube 5 rotates as a whole under the drive of the motor. Driven by the rotation of the flexible threaded tube 5, the bearing rings are conveyed forward along the flexible threaded tube 5 to the discharge port and enter the grinding machine through the feed port for processing. Because the bearing rings are relatively small, the rotation of the flexible threaded tube 5 effectively helps the bearing rings move forward.

[0015] Preferably, the tail end of the flexible threaded tube 5 is inserted into a rotating shaft 7 and rotates with the shaft 7. The rotating shaft 7 is mounted in a lower mounting base 8 via bearings. The lower mounting base 8 is mounted on a grinding machine. The driving mechanism includes a motor 9, the output end of which is provided with a driving pulley 10. The rotating shaft 7 is provided with a driven pulley 11, and the driving pulley 10 and the driven pulley 11 are connected by a transmission belt 12. When the motor 9 rotates, the driving pulley 10 rotates accordingly. The driving pulley 10 drives the driven pulley 11 to rotate via the transmission belt 12. The driven pulley 11 drives the rotating shaft 7 to rotate, thereby causing the flexible threaded tube 5 to rotate.

[0016] Preferably, the two ends of the rotating shaft 7 are provided with lower plastic sleeves 13. The tail of the flexible threaded tube 5 passes through the lower plastic sleeves 13 and rotates together with the lower plastic sleeves 13. The lower plastic sleeves 13 can prevent the flexible threaded tube 5 from wearing the rotating shaft 7. In this embodiment, the driven pulley 11 is provided at the end of the rotating shaft 7 and is integrally formed with the rotating shaft 7. The lower plastic sleeve 13 at one end is installed in the driven pulley 11.

[0017] Preferably, the head of the flexible threaded tube 5 is mounted on the upper mounting base 14 via a bearing. The upper mounting base 14 is mounted on the feeding vibratory plate 1 via a bracket 15, which facilitates installation. Specifically, the upper mounting base 14 is provided with an upper plastic sleeve 16, and the head of the flexible threaded tube 5 is mounted in the upper plastic sleeve 16 via a bearing. The upper plastic sleeve 16 can prevent the upper mounting base 14 from being worn due to the rotation of the flexible threaded tube 5.

[0018] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
