Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0028] Reference Figure 1-4 A high-speed bearing ring production feeding structure includes a feeding track 1, a bracket 2 and a fixed frame 3. A workpiece 12 rolls on the inner wall of the feeding track 1, and a motor 4 is fixedly provided on the top of the fixed frame 3. The power output shaft of the motor 4 is fixedly connected to a screw 1 5, and the outer edge of the screw 1 5 is threadedly connected to a slider 6. The outer side of the slider 6 is fixedly connected to a connecting frame 7. The bottom of the bracket 2 is fixedly assembled with a cylinder 8, and the outer side of the fixed frame 3 is fixedly installed with a material blocking plate 11 by a screw 10. The bottom of the feeding track 1 is rotatably connected to a frame 13 through a hinge 17, and the side wall of the frame 13 is fixedly assembled with a motor 14. The power output shaft of the motor 14 is fixedly connected to a screw 2 15, and the outer edge of the screw 2 15 is threadedly connected to an adjusting block 16. The bottom of the feeding track 1 is provided with an inclined surface 18.

[0029] See Figure 4 The output end of the cylinder 8 is fixedly connected to the top of the connecting frame 7, the bracket 2 is fixedly connected to the equipment, and the connecting frame 7 is slidably connected to the outside of the fixed frame 3, so that when the cylinder 8 is running, the connecting frame 7 can be used to drive the fixed frame 3 and the material blocking plate 11 to move up and down automatically, thereby changing the distance between the fixed frame 3 and the material blocking plate 11 during movement.

[0030] See Figure 3 The inner wall of the fixed frame 3 is fixedly equipped with a bearing seat 9, and the end of the screw 5 away from the motor 4 is fixedly connected to the inner ring of the bearing seat 9. The slider 6 is slidably connected to the inner wall of the fixed frame 3, so that it can limit the position of the screw 5 during rotation, thereby ensuring that the screw 5 will not easily deviate or swing in position during rotation.

[0031] See Figure 1 and Figure 2 The top of the adjusting block 16 is sloped, and the top of the adjusting block 16 fits against the inclined surface 18, so that the adjusting block 16 moves along the bottom of the inclined surface 18 to adjust the inclination angle of the feeding track 1, thereby ensuring that the position of the workpiece 12 on the inner wall of the feeding track 1 can be moved without the use of power and manpower.

[0032] See Figure 1 and Figure 2 The inner wall of the frame 13 is fixedly equipped with a positioning ring, and the end of the screw rod 15 away from the motor 14 is rotatably connected to the inner wall of the positioning ring. The bottom of the adjustment block 16 is slidably connected to the inner wall of the frame 13, so that the screw rod 15 can be positioned during rotation, ensuring that it can rotate stably in a parallel state with the inner wall of the frame 13 and the motor 14, and thus can stably drive the adjustment block 16 to move on the inner wall of the frame 13.

[0033] See Figure 4 A threaded hole is provided on the inner wall of the material blocking plate 11, and the threaded hole passes through the inner wall of the fixed frame 3. The screw 10 is threadedly connected to the inner wall of the threaded hole, so that the material blocking plate 11 can be stably installed on the outer side of the fixed frame 3 using the screw 10. After removing the screw 10, it is easy to separate the material blocking plate 11 from the fixed frame 3, and then it is easy to replace the material blocking plate 11 with different inner diameters according to the diameter of the workpiece 12.

[0034] See Figure 1 and Figure 2 A limit plate is provided on one side of the feeding track 1 close to the material blocking plate 11, and the limit plate is extended downward, so that the material blocking plate 11 can drive the workpiece 12 to move accurately along the limit plate toward the fine grinding processing station, and can roll with the outer cylindrical surface of the workpiece 12 to ensure the processing quality of the workpiece 12.

[0035] Working principle: When using this device, first, the material blocking plate 11 can be used to drive the workpiece 12 to move stably along the limit plate toward the fine grinding processing station, and can roll with the outer cylindrical surface of the workpiece 12 to ensure the processing quality of the workpiece 12. At the same time, the motor 4 can be driven to drive the screw 5 to rotate, thereby adjusting the position of the slider 6 and the connecting frame 7, thereby facilitating the operation of driving the cylinder 8 to adjust the material blocking plate 11 to different height positions, thereby facilitating the movement of workpieces 12 with different inner diameters. By removing the screw 10, it is convenient to move the blocking plate 11 to a different height position. The material shift plate 11 is separated from the fixed frame 3, which makes it easy to replace the material shift plate 11 with different inner diameters according to the diameter of the workpiece 12. At the same time, the driving motor 14 drives the screw rod 15 to rotate, which can drive the adjustment block 16 to slide on the inner wall of the frame 13, so that the adjustment block 16 moves along the bottom of the inclined surface 18 to adjust the inclination angle of the loading track 1, thereby ensuring that the position of the workpiece 12 on the inner wall of the loading track 1 can be moved without the use of power and manpower, thereby ensuring the speed of the workpiece 12 when moving.
