[0002] To remove microscopic unevenness and defects on the surface of steel balls, making the surface smoother, reducing surface roughness, and improving the service life and operational stability of bearings, grinding equipment is usually used to process the steel balls. For reference, see the relevant patent CN216098299U. Essentially, the grinding equipment drives the steel balls to be subjected to centrifugal force and friction, which produces an impact and grinding effect on the workpiece surface.

[0003] To explain the processing method of bearing steel balls: In the traditional grinding process, the grinding material will wear and break due to continuous collision, resulting in uneven particle size distribution. This may lead to uneven processing of bearing steel balls during the grinding operation. In order to ensure the surface finish and processing consistency of bearing steel balls, we provide a bearing steel ball grinding device based on multi-level gradient pressure adjustment to solve the above problems.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] The base unit includes a grinding base mounted on the top surface of the base plate, a grinding rotating plate rotatably connected inside the grinding base for grinding, and a limiting bracket fixedly mounted on the top surface of the grinding base for adjusting the grinding pressure.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a bearing steel ball grinding device based on multi-level gradient pressure adjustment. The steel ball to be ground and the grinding medium are placed inside the grinding base and located on the top surface of the grinding plate. Under the drive of the drive motor, the follower wheel is driven by the bevel gear to drive the grinding plate to rotate.

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] Example 1: As Figure 1-5As shown, this utility model provides a bearing steel ball grinding device based on multi-level gradient pressure adjustment, including a base plate 1, a base unit 2 for adjusting grinding pressure is provided on the top surface of the base plate 1, a step-type pressure applying mechanism 3 is provided on the top surface of the base unit 2, the base unit 2 includes a grinding base 21 installed on the top surface of the base plate 1, a grinding rotating plate 25 rotatably connected inside the grinding base 21 for grinding, and a limiting bracket 27 fixedly installed on the top surface of the grinding base 21 for adjusting grinding pressure, a bevel gear 22 rotatably connected inside the grinding base 21, and a drive motor 23 fixedly connected to one end of the top surface of the grinding base 21;

[0028] The output end of the drive motor 23 meshes with one end of the top surface of the bevel gear 22. A transmission belt 24 is movably connected to the outer surface of the output end of the drive motor 23. A follower wheel 26 is fixedly connected to the bottom surface of the grinding plate 25. The follower wheel 26 is rotatably connected to the inside of the bottom surface of the grinding base 21. The follower wheel 26 meshes with the bevel gear 22.

[0029] The drive motor 23 drives the transmission gear 33 to rotate through the transmission belt 24, which can ensure that the pressure during the grinding process increases as the grinding process progresses. The bevel gear 22 drives the grinding plate 25 to rotate through the follower wheel 26. By cooperating with the internal components of the pressure mechanism 3, the grinding operation of the steel ball is realized.

[0030] The limiting bracket 27 is internally connected to a movable locking block 28, and the outer surface of the movable locking block 28 is movably connected to a limiting spring 29, which is movably connected to the inside of the limiting bracket 27.

[0031] The limiting bracket 27 limits the movement of the clamping rod 36, ensuring that the movement trajectory of the clamping rod 36 is vertically downward. Under the push of the internal components of the pressurizing mechanism 3, the clamping rod 36 squeezes the movable clamping block 28 to retract. Through the multiple clamping blocks inside the movable clamping block 28, the clamping rod 36 is limited in a step-like manner, further realizing the step-like pressure on the top surface of the grinding plate 25.

[0032] In this embodiment, the steel balls to be ground and the grinding media are placed inside the grinding base 21 and located on the top surface of the grinding rotating plate 25. Driven by the drive motor 23, the follower wheel 26 is driven by the bevel gear 22 to rotate the grinding rotating plate 25. The grinding operation of the steel balls is realized through the cooperation of the pressure mechanism 3 and the base unit 2.

[0033] While the drive motor 23 drives the grinding plate 25 to grind the steel balls, it also drives the grinding plate 35 to press down. When the clamping rod 36 on the top surface of the grinding plate 35 contacts the movable clamping block 28, it will intermittently push the grinding plate 35 through the movable clamping block 28 and the internal components of the pressing mechanism 3, so as to satisfy the purpose of step-like pressure on the top surface of the grinding base 21.

[0034] Example 2: As Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the pressurizing mechanism 3 includes a fixed frame 31 installed on the top surface of the transmission belt 24, a rack 32 slidably installed inside the fixed frame 31 for pressurizing, and a limiting rod 38 movably installed inside the fixed frame 31 to limit the rack 32. The side of the fixed frame 31 is movably connected to a transmission tooth 33 that meshes with the rack 32. The transmission tooth 33 is movably connected inside the transmission belt 24. A spring rod 34 is fixedly connected inside the bottom surface of the rack 32. A grinding plate 35 is movably connected to the bottom surface of the spring rod 34. A locking rod 36 is slidably connected inside the limiting bracket 27 and fixedly connected to the top surface of the grinding plate 35. The locking rod 36 is movably connected inside the movable locking block 28.

[0035] The transmission gear 33 is fixed to the side of the fixed frame 31. The side of the transmission gear 33 is driven by the transmission belt 24, so that the transmission gear 33 can drive the rack 32 to press down. The top of the side of the rack 32 is provided with a groove that matches the limiting rod 38. The size of the grinding plate 35 matches the opening on the top surface of the grinding base 21. The locking rod 36 on the top surface of the grinding plate 35 cooperates with the base unit 2 assembly to limit the grinding plate 35. When the rack 32 presses down, it will first drive the spring rod 34 to retract. When the rack 32 continues to press down, it pushes the locking rod 36 to squeeze the internal components of the base unit 2, driving the grinding plate 35 to pressurize the inside of the base unit 2.

[0036] The limiting lever 38 is engaged in the slot opened at the top side of the rack lever 32. A pull rod 37 is fixedly connected to the side of the limiting lever 38, and a clamping spring 39 is sleeved on the outer surface of the pull rod 37.

[0037] The limiting lever 38 moves within the inner groove of the fixing frame 31 and slides on the outer surface of the rack 32. The clamping spring 39 applies pressure to the limiting lever 38. When the rack 32 moves to its lowest point, the clamping spring 39 pushes the limiting lever 38 out and engages it in the side groove of the rack 32.

[0038] In this embodiment, driven by the transmission belt 24, the rotating transmission gear 33 drives the rack 32 to press down, and at the same time drives the grinding plate 35 to press down into the base unit 2. It cooperates with the internal components of the base unit 2 to realize the grinding operation of the steel ball. As the rack 32 continues to press down, the spring rod 34 will retract because the locking rod 36 is limited by the movable locking block 28. After the spring rod 34 retracts to its limit, the rack 32 will push the locking rod 36 to move inside the movable locking block 28, realizing the intermittent pressing of the grinding plate 35 and satisfying the purpose of stepped pressurization.

[0039] When the rack rod 32 is pressed down to its lowest point, the clamping spring 39 will push out the limiting lever 38 that is retracted inside the fixing frame 31, restricting the rack rod 32 to its lowest point and maintaining a continuous high pressure state inside the base unit 2.

[0040] The working principle of this bearing steel ball grinding device based on multi-level gradient pressure adjustment will be explained in detail below.

[0041] like Figure 1-5 As shown, the basic grinding operation of the steel ball is achieved through the cooperation of the base unit 2 and the pressurizing mechanism 3. At the same time, the pressurizing mechanism 3 will intermittently pressurize the inside of the base unit 2, and achieve a finer grinding operation of the steel ball through the step-like pressurization.

[0042] The steel balls and grinding media to be ground are placed inside the grinding base 21 and located on the top surface of the grinding plate 25. Driven by the drive motor 23, the follower wheel 26 is driven by the bevel gear 22 to rotate the grinding plate 25. Through the cooperation of the pressure mechanism 3 and the base unit 2, the grinding operation of the steel balls is realized.

[0043] Driven by the transmission belt 24, the rotating transmission gear 33 will drive the rack 32 to press down, and at the same time drive the grinding plate 35 to press down into the base unit 2. It will cooperate with the internal components of the base unit 2 to achieve the grinding operation of the steel ball. As the rack 32 continues to press down, the spring rod 34 will retract due to the limit of the locking rod 36 by the movable locking block 28. After the spring rod 34 retracts to its limit, the rack 32 will push the locking rod 36 to move inside the movable locking block 28, so as to achieve the intermittent pressing of the grinding plate 35 and meet the purpose of stepped pressurization.

[0044] When the rack rod 32 is pressed down to its lowest point, the clamping spring 39 will push out the limiting lever 38 that is retracted inside the fixing frame 31, restricting the rack rod 32 to its lowest point and maintaining a continuous high pressure state inside the base unit 2.

[0045] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all modifications or improvements made without departing from the spirit and concept of the present invention are within the protection scope of the present invention.
