Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal surface treatment technology, specifically to a cleaning device for grinding bearing steel balls. Background Technology
[0002] In bearing manufacturing, steel balls are a key component, and their quality directly affects the bearing's service life and operational stability. Grinding is an important step in steel ball manufacturing, achieving the required dimensional accuracy and surface finish. However, after grinding, the steel ball surface will be contaminated with abrasive particles, metal shavings, and lubricating oil. If these residues are not thoroughly removed, they will negatively impact the overall performance of the bearing.
[0003] Traditional cleaning methods (such as high-pressure spraying or simple brushing) primarily rely on mechanical force and water jet impact to remove larger particulate contaminants from the surface of steel balls, such as large metal debris and coarse abrasive particles. However, these methods are significantly inadequate in handling microscopic contaminants, especially tiny abrasive particles, fine metal debris, and residual lubricating oil films, which are difficult to remove completely. These microscopic contaminants, due to their extremely small size and potential embedding in the micropores or depressions of the steel ball surface, cannot be completely removed by simple mechanical rinsing or brushing.
[0004] To address this issue, a special cleaning device for grinding bearing steel balls was designed to solve the aforementioned technical problems. Utility Model Content

[0011] Optionally, it also includes a reflux chamber, a reflux pump pipe, and a filter element. Each corner of the upper part of the sealed base is provided with a fixing column, and the reflux chamber is installed together between the fixing columns.

[0026] The embodiments of this utility model will be described below with reference to the accompanying drawings.
[0027] Example: A cleaning device for grinding bearing steel balls, such as... Figures 1-10As shown, the device includes a sealing base 1, which forms the main frame of the entire unit, providing a sealed working environment to prevent cleaning fluid leakage and isolate external vibrations. The sealing base 1 is typically made of metal or high-strength plastic. Various components are fixed inside or outside the device by bolts, welding, or snap-fits. A mesh frame 11 is installed in the upper part of the sealing base 1 to hold the steel balls to be cleaned. A transmission pipe 111 for transporting the steel balls is connected to the upper rear of the mesh frame 11. The portion of the transmission pipe 111 that penetrates the sealing base 1 is a through-hole, and this through-hole is designed at an angle to ensure even distribution of the steel balls. A discharge port is opened in the lower part of the mesh frame 11, and a cleaning brush assembly 12 is installed inside the mesh frame 11. The cleaning brush assembly 12 consists of a support frame and several brush rollers. It removes large particulate contaminants from the surface of the steel ball through mechanical friction. The support frame is fixedly connected to the upper part of the sealing base 1, while the brush rollers are rotatably connected to the lower part of the support frame and arranged symmetrically. A drive unit for rotating the cleaning brush assembly 12 is located on the upper part of the mesh frame 11. An ultrasonic isolation chamber 2 is installed in the lower part of the sealing base 1. The ultrasonic isolation chamber 2 provides an independent space and utilizes an ultrasonic generator to produce a cavitation effect, further removing microscopic contaminants from the surface of the steel ball. The outer wall of the ultrasonic isolation chamber 2 and the inner wall of the sealing base 1 have a gap for air circulation to reduce the impact of external vibrations. The mesh frame 11 is placed inside the ultrasonic isolation chamber 2. Both sides of the part are provided with a support frame 21, and an electric push rod 22 is installed on the upper part of the support frame 21. The telescopic end of the electric push rod 22 is provided with a baffle 23. The near end faces of the baffles 23 on both sides are in close contact. The support frame 21 supports the electric push rod 22, and the electric push rod 22 controls the opening and closing of the baffles 23, thereby precisely controlling the feeding process of the steel ball. A feeding regulator 24 is installed through the lower part of the sealing base 1. The feeding regulator 24 is used to control the feeding process of the steel ball from the mesh frame 11, ensuring that the quantity and timing of each feeding meet the requirements. The upper part of the feeding regulator 24 is connected to the lower discharge port of the mesh frame 11. The upper part of the feeding regulator 24 has shielding grooves on both sides. The baffles 23 on both sides slide and adapt to the corresponding shielding grooves. When the near end faces are in close contact, the feeding pipe of the feeding regulator 24 is closed. A cleaning liquid tank 3 is installed on the top of the sealing base 1. The high-pressure nozzle 31 at the bottom of the cleaning liquid tank 3 is placed on the upper part of the mesh frame 11. The cleaning liquid tank 3 stores cleaning liquid and sprays it onto the surface of the steel ball through the high-pressure nozzle 31. It works with the cleaning brush group 12 to remove contaminants. An addition pipe 32 is connected to the upper side of the cleaning liquid tank 3.

The wire mesh frame 44 supports the steel balls.
[0028] like Figure 5 As shown, the drive assembly includes a large gear 13, small gears 14, and a motor 15. The large gear 13 is rotatably connected to the center of the upper part of the support frame. The large gear 13 is connected to one of the corresponding brush rollers below it. Multiple small gears 14 are rotatably connected to the upper part of the support frame along the circumference, meshing with the large gear 13. The small gears 14 are also connected to the corresponding brush rollers below them. The motor 15 with its output shaft facing downward is installed at the center of the upper part of the sealing base 1. The output shaft of the motor 15 is connected to the large gear 13, and a stabilizing component is provided at the connection between the output shaft of the motor 15 and the large gear 13. The drive assembly drives the large gear 13 to rotate through the motor 15. The large gear 13 meshes with multiple small gears 14, driving the symmetrically distributed brush rollers to form a vortex motion, which enhances the cleaning effect.
[0029] like Figure 6 As shown, it also includes a limiting seat 42. The rear part of the drying chamber 4 is provided with a limiting seat 42 that abuts against the rear side of the second wire mesh frame 44. The limiting seat 42 is used to fix the position of the second wire mesh frame 44 to prevent it from moving or tilting during the drying process, and to ensure that the steel balls can be heated evenly. The limiting seat 42 adopts a planar contact or a design with a buffer material (such as a rubber pad) to reduce vibration and protect the second wire mesh frame 44.
[0030] like Figure 1 and Figure 2 As shown, it also includes a steam delivery pump pipe 5. Steam delivery pump pipes 5 are installed on both sides of the outside of the drying chamber 4. One end of the steam delivery pump pipe 5 extends into the drying chamber 4, and the other end is connected to the upper side of the sealing base plate, with its output interface facing upward. The steam delivery pump pipe 5 is used to discharge the steam generated during the drying process and maintain the dry environment inside the drying chamber 4.
[0031] like Figure 1 , Figure 2 and Figure 8As shown, it also includes a reflux chamber 6, a reflux pump pipe 61, and a filter element 62. Each corner of the upper part of the sealing base 1 is equipped with a fixing post, and the reflux chamber 6 is installed between these fixing posts. An isolation plate is located in the middle of the reflux chamber 6, and a two-way control valve is installed on the lower side of the isolation plate. The reflux chamber 6 is divided by the isolation plate into a temporary storage chamber and a filtration chamber. Reflux pump pipes 61 are connected to the lower parts of both sides of the reflux chamber 6. The reflux pump pipes 61 on both sides are staggered, and the end of the forward reflux pump pipe 61 passes through the sealing base. The bottom of the reflux chamber 6 is connected to the bottom of the ultrasonic isolation chamber 2. The end of the rear reflux pump pipe 61 passes through the upper side of the sealing base 1 and is connected to the upper side of the ultrasonic isolation chamber 2. A filter element 62 is installed in the rear of the reflux chamber 6. The cleaning liquid filtered by the filter element 62 is input into the ultrasonic isolation chamber 2 through the rear reflux pump pipe 61. The reflux chamber 6 is used to store and filter the cleaning solution. The reflux pump pipe 61 pumps the filtered cleaning liquid back into the ultrasonic isolation chamber 2. The filter element 62 removes contaminants from the solution.
[0032] like Figure 1 As shown, it also includes a controller 7, which is installed on the outer side of the sealed base 1 to control the operation of each electrical component.
[0033] The ground steel balls slide into the mesh frame 11 through the inclined transmission pipe 111. The inclined design of the transmission pipe 111 ensures that the steel balls are evenly distributed. After the steel balls enter the mesh frame 11, the cleaning liquid tank 3 injects a mixture of cleaning liquid and water through the addition pipe 32. The solution is sprayed out under pressure from the high-pressure nozzle 31, evenly covering the surface of the steel balls. The moving assembly starts, and the motor 15 drives the large gear 13 to rotate. The large gear 13 meshes with multiple small gears 14, driving the symmetrically distributed brush rollers to form a vortex motion. The brush rollers in the cleaning brush assembly 12 generate friction with the surface of the steel balls, and the high pressure... The solution sprayed from the high-pressure nozzle 31 removes abrasives and metal debris from the surface of the steel ball. After cleaning the steel ball, the solution flows into the ultrasonic isolation chamber 2, gradually accumulating to form a cleaning solution pool. The ultrasonic generator inside the ultrasonic isolation chamber 2 starts working, generating a cavitation effect in the solution to further remove microscopic contaminants from the surface of the steel ball. After ultrasonic cleaning is completed, the controller 7 instructs the electric push rod 22 to retract synchronously, the side baffles 23 separate along the shielding groove, opening the channel of the feeding regulator 24, and the cleaned steel ball falls into the feeding regulator 24. The steel ball falls into the drying chamber 4 and into the mesh frame 44. The heating device inside the drying chamber 4 is activated, and the sealing door 43 closes. At the same time, the air pressure lock or mechanical locking device on the outside of the sealing door 43 is activated to ensure that the sealing door 43 is tightly fitted to the drying chamber 4, forming a sealed space. During the drying process, the sealing door 43 remains tightly closed to prevent outside air from entering and internal heat from escaping, ensuring drying efficiency. After drying is completed, the controller 7 instructs the air pressure lock or mechanical locking device to release, and the sealing door 43 is opened automatically or manually, making it easy for the operator to remove the steel ball from the mesh frame 44. 4. The bottom contacts the buffer pad 41 to reduce the impact damage of the steel ball when it falls into the drying chamber 4. In addition, the steam generated during the drying process is discharged from the top through the steam delivery pump pipe 5 to maintain a dry environment in the drying chamber 4. The washed solution is transported to the return chamber 6 through the return pump pipe 61. The isolation plate in the return chamber 6 divides the solution into a temporary storage chamber and a filtration chamber. The bidirectional control valve regulates the flow of the solution. The solution is filtered by the filter element 62 to remove contaminants. The filtered clean solution is pumped back into the ultrasonic isolation chamber 2 through the return pump pipe 61 to realize the recycling of the solution.
