Description

Technical Field

[0001] This utility model relates to the field of bearing steel ball processing technology, and in particular to an automatic feeding device for grinding bearing steel balls. Background Technology

[0002] Bearing steel balls are key components used in rolling bearings and are widely used in many fields such as machinery, automobiles, aerospace, and railways. They are typically made of high-carbon chromium steel or other special alloy steels, and undergo precision machining and heat treatment to ensure extremely high hardness, wear resistance, and fatigue resistance. These properties enable bearing steel balls to operate stably for extended periods under high-speed rotation and heavy load conditions, reducing friction and extending equipment life.

[0003] Bearing steel balls require continuous feeding during grinding. The current method is manual feeding, which is usually slow and unstable, making it difficult to match the efficient operation of automated equipment. This limits the overall production line capacity, and long-term repetitive manual operation can easily lead to worker fatigue, further reducing work efficiency.

[0004] Therefore, it is necessary to design an automatic feeding device for grinding bearing steel balls to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the above-mentioned shortcomings, the technical problem of this utility model is to provide an automatic feeding device for grinding bearing steel balls.

[0006] The technical implementation scheme of this utility model is as follows: an automatic feeding device for grinding bearing steel balls, including a feeding frame, a partition, a mounting frame, a first motor and a control plate. The feeding frame has an inclined structure, and a partition is fixedly connected inside the feeding frame. Multiple through holes are opened on the partition. A discharge port is opened on the left side of the feeding frame. A mounting frame is fixedly connected to the top of the feeding frame. A first motor is fixedly connected to the front of the mounting frame. A control plate is fixedly connected to the output shaft of the first motor.

[0007] Optionally, it also includes a liquid storage tank, an inlet pipe, a sealing cap, an inlet pipe, a water pump, an annular pipe, and nozzles. The liquid storage tank is fixedly connected to the bottom of the feeding frame. The liquid storage tank is connected to and communicates with the inlet pipe at the top. A sealing cap is threadedly connected to one end of the inlet pipe. Inlet pipes are connected to and communicate with both sides of the liquid storage tank. A water pump is connected to and communicates with both inlet pipes. An annular pipe is connected to and communicates with the upper ends of the inlet pipes. Multiple nozzles are connected to and communicated in an annular array on one side of the annular pipe.

[0008] Optionally, it also includes a liquid outlet pipe, which is symmetrically connected to and communicates with the left side of the feeding frame.

[0009] Optionally, it also includes a second motor, a rotating shaft, and a turntable. The second motor is fixedly connected to the right side of the feeding frame, and the rotating shaft is fixedly connected to the output shaft of the second motor. The bottom of the rotating shaft is fixedly connected to a turntable that is rotatably connected inside the feeding frame, and the turntable has a notch.

[0010] Optionally, the turntable is equipped with a ring array of multiple buffer bars.

[0011] Optionally, it also includes a third motor, a cleaning brush, an adsorption cylinder, a drive wheel, and a belt. The third motor is fixedly connected to the front of the feeding frame. The cleaning brush, which is rotatably connected to the output shaft of the third motor, is fixedly connected to the feeding frame. The cleaning brush abuts against the top surface of the partition. Two adsorption cylinders are rotatably connected to the left side of the feeding frame. The two adsorption cylinders are located to the left of the cleaning brush. A connecting wheel is fixedly provided on the cleaning brush and one of the adjacent adsorption cylinders. A connecting belt is wound around the two connecting wheels. A drive wheel is fixedly connected to both adsorption cylinders. A belt is wound between the two drive wheels.

[0012] The beneficial effects are: 1. This utility model uses a first motor to drive the material control plate to rotate, thereby automatically opening and closing the discharge port and completing the automatic feeding of bearing steel balls. The inclined feeding frame guides the steel balls smoothly into the grinding device, which improves production efficiency, reduces manual intervention, and ensures the safety and stability of operation. It is suitable for various automated production lines.

[0013] 2. This utility model uses a water pump to draw the grinding liquid from the storage tank into the delivery pipe, and then sprays it out from the nozzle through the annular pipe to achieve automatic spraying of the steel ball. The nozzle is pointed downwards to ensure uniform spraying, which pre-treats the steel ball for the next grinding process, improves production efficiency and reduces manual intervention.

[0014] 3. This utility model uses a third motor, whose output shaft drives the cleaning brush to rotate and remove impurities from the surface of the steel ball. Then, the two adsorption cylinders rotate synchronously through the connecting wheel, connecting belt, transmission wheel and belt to adsorb excess grinding liquid on the surface of the steel ball, which improves the cleaning and adsorption efficiency and ensures the cleanliness and quality of the steel ball surface.

Detailed Implementation

[0022] 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.

[0023] Example: An automatic feeding device for grinding bearing steel balls, such as... Figures 1-5 As shown, the device includes a feeding frame 1, a partition 2, a mounting frame 4, a first motor 6, and a control plate 5. The feeding frame 1 is inclined, and the partition 2 is welded inside the feeding frame 1. The partition 2 has multiple through holes 3. A discharge port is located on the left side of the feeding frame 1. The mounting frame 4 is welded to the top right side of the feeding frame 1. The first motor 6 is mounted on the front side of the mounting frame 4 by screws. The output shaft of the first motor 6 passes through the mounting frame 4 and is welded to the control plate 5, which prevents steel balls from flowing out of the discharge port. Steel balls are poured into the feeding frame 1. When grinding is required, the device... When feeding, start the first motor 6. The output shaft of the first motor 6 drives the control plate 5 to rotate clockwise, thereby opening the discharge port. Since the feeding frame 1 is designed to be inclined, the steel balls will flow from the right end to the left end of the feeding frame 1 along the inclination angle, and enter the grinding device through the discharge port for grinding. When feeding is not required, the output shaft of the first motor 6 rotates counterclockwise, driving the control plate 5 to move to the discharge port position, completely blocking the discharge port, so that the steel balls cannot flow out. After use, the first motor 6 can be turned off.

[0024] like Figure 1 and Figure 3As shown, it also includes a storage tank 8, an inlet pipe 9, a sealing cap 10, an inlet pipe 11, a water pump 12, an annular pipe 13, and nozzles 14. The storage tank 8 is welded to the bottom right side of the discharge frame 1. The upper right side of the storage tank 8 is connected to and connected to the inlet pipe 9. The right end of the inlet pipe 9 is threadedly connected to the sealing cap 10. The front and rear sides of the storage tank 8 are both connected to and connected to the inlet pipes 11. Both inlet pipes 11 are connected to and connected to the water pump 12. The upper ends of the inlet pipes 9 are connected to and connected to the annular pipe 13. Multiple nozzles 14 are connected in a ring array inside the annular pipe 13. The water pump 14 is started. 2. The grinding fluid in the storage tank 8 is drawn into the infusion pipe 11, and then flows through the water pump 12 and the annular pipe 13 and is sprayed out from the nozzle 14. Since the nozzle 14 is facing downward, the grinding fluid can be sprayed onto the steel ball. Excess spray fluid will flow from the through hole 3 into the space between the partition plate 2 and the feeding frame 1. When the grinding fluid needs to be replenished, rotate the sealing cover 10 counterclockwise to open the inlet pipe 9, and then pour the grinding fluid into the storage tank 8 until the storage tank 8 is three-quarters full. Finally, rotate the sealing cover 10 clockwise to close the inlet pipe 9. If it is not necessary to spray the steel ball, turn off the water pump 12.

[0025] It also includes a liquid outlet pipe 7. The left side of the feeding frame 1 is symmetrically connected to the liquid outlet pipe 7. The two liquid outlet pipes 7 are connected to external pipes to export the grinding liquid in the feeding frame 1.

[0026] like Figure 1 and Figure 4 As shown, it also includes a second motor 15, a rotating shaft 16, and a turntable 17. The second motor 15 is installed on the top right side of the feeding frame 1 by screws. The rotating shaft 16 is welded to the output shaft of the second motor 15. The turntable 17, which is rotatably connected inside the feeding frame 1, is welded to the bottom of the rotating shaft 16. The turntable 17 has a notch. When steel balls are poured into the turntable 17, the output shaft of the second motor 15 drives the rotating shaft 16 to rotate, thereby rotating the turntable 17. The steel balls roll inside the turntable 17. Due to the centrifugal force, the steel balls will move along the edge of the turntable 17 to ensure that the surface of the steel balls is more evenly covered when the polishing liquid is sprayed. After the turntable 17 rotates once, the steel balls can flow out from the notch set on the edge of the turntable 17 and enter the feeding frame 1.

[0027] Multiple buffer strips are welded in a ring array on the inner bottom surface of turntable 17, which can slow down the rolling speed of the steel ball during the rotation of turntable 17.

[0028] like Figure 1 , Figure 5 and Figure 6As shown, it also includes a third motor 18, a cleaning brush 19, an adsorption cylinder 20, a transmission wheel 21, and a belt 22. The third motor 18 is screwed onto the front side of the feeding frame 1. The cleaning brush 19, which is rotatably connected to the feeding frame 1, is welded to the output shaft of the third motor 18. The cleaning brush 19 abuts against the top surface of the partition plate 2. Two adsorption cylinders 20 are rotatably connected to the top left side of the feeding frame 1. The two adsorption cylinders 20 are located directly to the left of the cleaning brush 19. Connecting wheels are welded to the cleaning brush 19 and one of the adjacent adsorption cylinders 20. Connecting belts are wound around the two connecting wheels. The two adsorption cylinders 20 are welded with connecting wheels. A drive wheel 21 is connected, and a belt 22 is wound between the two drive wheels 21. When the third motor 18 is started, the output shaft of the third motor 18 drives the cleaning brush 19 to rotate clockwise. When the steel ball flows in the feeding frame 1, the cleaning brush 19 can remove impurities from the surface of the steel ball. Then, under the action of the connecting wheel and the connecting belt, one of the adsorption cylinders 20 starts to rotate clockwise. Then, through the transmission of the drive wheel 21 and the belt 22, both adsorption cylinders 20 rotate clockwise at the same time, thereby adsorbing the excess grinding liquid on the surface of the steel ball. If cleaning and adsorption operations are not required, simply turn off the third motor 18.

[0029] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
