[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 、 Figure 2, An embodiment provided by the present utility model: A feeding mechanism for a turntable of a bearing grinder, including a conveying box 1. A driving mechanism is arranged at the rear side of the conveying box 1. The driving mechanism includes a stepping motor 2. The stepping motor 2 can accurately control the rotation angle of its output shaft, facilitating the adjustment of the rotation speed and rotation angle of its rotating shaft, and can be adaptively adjusted according to different requirements, improving the accuracy of control. The stepping motor 2 is arranged at the rear side of the conveying box 1 and is fixed on an external platform to ensure the stability of the stepping motor 2 during operation. The front side of the output shaft of the stepping motor 2 is fixedly connected to a rotating shaft 3. The stepping motor 2 provides power to drive the rotating shaft 3 to rotate. A turntable mechanism is arranged inside the conveying box 1.

[0032] Refer to Figure 1 , Figure 4 , The turntable mechanism includes a circular plate 4. The circular plate 4 is fixedly installed on the front side of the rotating shaft 3. A pressing block 5 is fixedly connected to the front side of the circular plate 4. The central axis of the circular plate 4 and the central axis of the pressing block 5 are on the same straight line, improving the stability of the rotation of the pressing block 5. A diversion plate 6 is fixedly connected to the front side of the circular plate 4. The number of the diversion plates 6 is set to be multiple. The multiple diversion plates 6 are arranged at equal angular intervals in a ring on the circumferential surface of the pressing block 5. The continuous rotation of the diversion plate 6 driven by the rotation of the circular plate 4 transports the bearing housing from the bottom of the conveying box 1 to the top of the conveying box 1.

[0033] Refer to Figure 1 - Figure 3 , A pressing mechanism is arranged inside the conveying box 1. The pressing mechanism includes a pressing plate 7, a connecting rod 8, a slider 9, and a guiding block 12. The pressing plate 7 is slidably installed on the inner wall of the conveying box 1. The bearing housing is pressed against the inner wall of the conveying box 1 by the pressing plate 7, so that a reasonable pressure is maintained between the bearing housing and the inner wall of the conveying box 1, reducing the phenomena of deviation and dropping when the bearing housing is transported upward, and improving the stability of the bearing housing during transportation. The front side of the pressing plate 7 is hinged to the rear side of the connecting rod 8. The end of the connecting rod 8 away from the pressing plate 7 is hinged to the front side of the slider 9. The number of the sliders 9 is set to be multiple. The movement of the pressing plate 7 drives the multiple sliders 9 to approach or move away from each other through the transmission of the connecting rod 8.

[0034] Refer to Figure 2 , Figure 3, a chute 10 that matches the slider 9 is provided on the front side of the inner wall of the pressing plate 7. The slider 9 is slidably installed on the inner wall of the chute 10. The sliding direction of the slider 9 is left - right sliding. The slider 9 is elastically connected to the inner wall of the pressing plate 7 through a spring 11. By setting the spring 11, multiple sliders 9 have a tendency to approach each other. The guide block 12 is fixedly installed on the inner wall of the chute 10. Guide grooves 13 that match the guide block 12 are provided on the upper and lower sides of the slider 9. The guide block 12 slides on the inner wall of the guide groove 13. By setting the guide groove 13, the displacement directions of the guide block 12 and the slider 9 are guided, enabling the slider 9 to perform a more precise linear motion and improving the stability of the displacement of the slider 9. A cavity 14 for stabilizing the bearing housing is provided inside the conveying box 1.

[0035] Refer to Figure 1 , Figure 4 , a feeding box 15 for receiving the bearing housing produced in the previous process is fixedly connected to the left side of the conveying box 1. A feeding groove 16 is provided on the left side inside the feeding box 15. An inclined groove 17 is provided on the right side inside the feeding box 15. By setting the inclined groove 17, it is convenient for the bearing housing to roll to the bottom left side of the conveying box 1 under the action of gravity. A bevel edge 18 is provided inside the feeding box 15. By setting the bevel edge 18, the bearing housing can enter the inside of the conveying box 1 in a vertical state, ensuring the accuracy of the initial position of the bearing housing and facilitating the subsequent conveying work. A discharging box 19 for conveying the bearing housing to the next process position is fixedly connected to the right side of the conveying box 1.

[0036] Working principle: When in use, the bearing housing after being processed in the previous production process enters the inside of the feeding box 15, and through the way that the latter bearing housing squeezes the former bearing housing, multiple bearing housings move towards the direction close to the conveying box 1. When the bearing housing moves to the position of the inclined groove 17, under the action of the bevel edge 18, the bearing housing will vertically enter the inside of the inclined groove 17, and then roll towards the bottom of the conveying box 1 under the action of gravity, waiting for the turntable mechanism to work for conveying the bearing housing.

[0037] Then start the power supply of the stepping motor 2. The stepping motor 2 works to drive the rotating shaft 3 to rotate. The rotating shaft 3 rotates to drive the circular plate 4 to rotate. The circular plate 4 rotates to drive multiple flow - dividing plates 6 to rotate around the central axis of the extrusion block 5. The flow - dividing plates 6 move to push the bearing housing towards the top of the conveying box 1, and through the way that the lower bearing housing squeezes the lower bearing housing, multiple bearing housings can continuously displace towards the top of the conveying box 1, improving the automation and working efficiency of processing. Finally, the bearing housing will enter the working range of the next process from the discharging box 19, and the discharging direction and state of the bearing housing are accurate, which is beneficial to improving the accuracy and processing quality of the next process operation.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
