Description

Technical Field

[0001] The invention relates to the technical field of bearing ball cleaning equipment, and in particular to an automatic bearing ball cleaning system. Background Art

[0002] In modern industrial production, bearings are key components in mechanical equipment, and their performance directly affects the operating efficiency and life of the equipment. As the core component of the bearing, the surface cleanliness of the bearing ball has a vital impact on the overall performance of the bearing. Traditional bearing ball cleaning methods mostly use manual cleaning or simple mechanical cleaning, which have problems such as low cleaning efficiency, uneven cleaning effect, and easy damage to the ball surface.

[0003] Although manual cleaning methods are flexible, they are limited by the operator's skill level and work attitude, and the cleaning quality is difficult to guarantee. In addition, they are inefficient and not suitable for large-scale production needs. Simple mechanical cleaning methods, such as using a brush or a high-pressure water gun, improve cleaning efficiency, but because the cleaning force is difficult to accurately control, it is easy to scratch or damage the ball surface, affecting the service life of the bearing.

[0004] In addition, traditional cleaning methods often fail to completely remove oil and tiny particles on the surface of the ball. These residues may accelerate the wear of the bearing during operation, reducing the accuracy and reliability of the bearing. Therefore, the development of an automatic cleaning system that can be efficient, uniform, and cause little damage to the ball surface has become an urgent problem to be solved in the bearing manufacturing industry.

[0005] In recent years, with the development of automation technology, some automatic cleaning equipment has begun to be used in the cleaning process of bearing balls. For example, a Chinese patent (application number: 202010600673.6) discloses a surface rust treatment device for bearing steel balls for mechanical manufacturing, including a box body, the top outer wall of the box body is fixedly connected to a fixing frame, and the inner wall of the fixing frame is provided with a plurality of threaded holes, the inner wall of the threaded hole is threadedly connected with a nozzle, and the inclination angle between the nozzle and the fixing frame is 10°-80°, the top outer wall of the fixing frame is fixedly connected to a box cover, and the top outer wall of the box cover is provided with a feed port, the inner wall of the feed port is fixedly connected to a feed pipe, and the inner wall of the feed pipe is provided with a plurality of first barbs, and the outer walls on both sides of the feed pipe are fixedly connected with elastic bands. The present invention can make the bearing steel balls reciprocate on the guide plate, can effectively remove rust from the bearing steel balls, can improve the rust removal efficiency of the device for the bearing steel balls, can treat the stubborn rust on the rollers, and can prevent the bearing steel balls from gathering together and interfering with the rust removal of the bearing steel balls.

[0006] However, when the equipment is in use, the bearing balls may collide with each other, causing damage to the surface of the bearing balls, which will lead to increased material loss during the cleaning process. Summary of the invention

[0007] In order to solve the above problems, an embodiment of the present invention provides an automatic bearing ball cleaning system, which has a good cleaning effect and does not cause wear to the surface of the steel ball.

DETAILED DESCRIPTION

[0033] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0034] Example 1

[0035] See also Figure 1-9 The automatic cleaning system for bearing balls includes a lower hopper 1, a distributor 2, a conveying device and a scrubbing device which are sequentially installed. The distributor 2 includes a conveying roller 15 located between the lower hopper 1 and the conveying device. A plurality of circular distributor plates 16 distributed sequentially along the length direction thereof are installed on the outside of the conveying roller 15. A snap-fitting gap 27 is reserved between two adjacent circular distributor plates 16. A guide plate is installed between the lower hopper 1 and the distributor 2. A comb-shaped extension plate is provided at one end of the guide plate facing the distributor 2. The number and position of the extension plates correspond to the snap-fitting gap 27, which can prevent the material from falling during the falling process. An inner concave portion distributed along the circumferential direction thereof is provided at the edge position of each distributor plate 16. After the installation is completed, the inner concave portions on the plurality of distributor plates 16 form a groove 17 for placing the material. The distribution of the groove 17 and the rotation speed of the conveying roller 15 can be used to control the material discharge speed and the material discharge amount, so as to ensure that the bearing balls can fall evenly during the discharge.

[0036] The conveying device includes a frame 18, and transmission chains 19 are installed on both sides of the upper part of the frame 18. A cross brace 20 is installed between the two transmission chains 19. The transmission chain 19 starts to run under the drive of the driving motor and the gear, thereby driving the cross brace 20 to move. The number of cross braces 20 is multiple, and the upper surface of each cross brace 20 is provided with a material blocking ridge 21. The material blocking ridge 21 includes a plurality of limit plates 24 distributed along the length direction of the cross brace 20. The limit plates 24 are triangular and the width gradually decreases from bottom to top. A flow gap 25 is provided between two adjacent limit plates 24. A through groove 26 corresponding to the position of the flow gap 25 is opened on the cross brace 20. The design of the flow gap 25 and the through groove 26 can facilitate the rapid falling of cleaning oil in the cleaning step to avoid the accumulation of cleaning oil on the conveying device. The material blocking ridge 21 between the two adjacent cross braces 20 forms a storage groove 22 for placing materials, which is used for limiting the ball bearing during the conveying process, and cooperates with the distributor 2 to control the moving speed of the material. To ensure that there is no accumulation when the material distributor enters the scrubbing device, guide plates 23 are installed at both ends of the frame 18. The guide plates 23 include a base plate 28. The base plate 28 is provided with a comb-shaped connecting extension plate 29 at one end facing the cross brace 20. The position and number of the connecting extension plates 29 correspond to the flow gap 25. Among them, the guide plate 23 near one end of the distributor 2 is provided with a comb-shaped extension plate corresponding to the position and number of the clamping gap 27. The design of the connecting extension plate 29 and the extension plate can reduce the transition gap at the connection of each device to avoid leakage at the transition gap during the transportation of the bearing steel balls. At the same time, the design of the connecting extension plate 29 and the extension plate can extend the conveying distance when the bearing steel balls are transferred to avoid the bouncing of the bearing balls during movement after the height difference occurs at the connection of the two connecting devices due to the rotation during the transportation process. The connecting extension plate 29 and the extension plate can be used to convey the bearing balls to the bottom of the groove 17 and the storage groove 22, thereby increasing the stability of material transportation.

[0037] A spray head 3 is installed above the conveying device, and a clean oil recovery bin corresponding to the position of the spray head 3 is installed below. The spray head 3 is used to rinse and moisten the material surface during the material conveying process. A circulation pipeline connected to the spray head 3 is installed on the clean oil recovery bin for the recovery and reuse of the clean oil.

[0038] The scrubbing device includes a rubbing roller 4 and a kneading device 5. The kneading device 5 includes a shell 7. An arc-shaped chamber 8 that matches the shape of the rubbing roller 4 is preset on the inner side of the shell 7. The circumference of the arc-shaped chamber 8 is greater than half of the circumference of the rubbing roller 4. The rubbing roller 4 is tilted downward when installed, that is, the opening at the feed end of the feed gap 6 is greater than the opening at the discharge end, which can extend the rubbing time of the material and enhance the cleaning effect. A feed gap 6 connected to the discharge end of the conveying device is reserved between the rubbing roller 4 and the inner side wall of the arc-shaped chamber 8. A driving device that drives the shell 7 to reciprocate is installed on the outer side of the shell 7. The driving device can drive the shell 7 to move back and forth along the axial direction of the rubbing roller 4 to achieve the scrubbing action of the material entering the feed gap 6. Pads 9 are provided on the side walls of the rubbing roller 4 and the arc-shaped chamber 8. The pads 9 are made of rubber or sponge material, which can increase the bearing ball when passing through. The friction force can extend the passing time of the material and improve the scrubbing effect. At the same time, it can also prevent the bearing steel balls from being damaged by hard friction with the equipment when passing through. The driving device includes a transmission rod 10 installed on the outside of the shell 7 and installed along its length direction. A motor 11 is provided at one end of the transmission rod 10. A driving disk 12 is provided at the output end of the motor 11. A connecting column is provided on the driving disk 12. The connecting column is installed on the radius of the driving disk 12. The connecting column and the transmission rod 10 are connected by a swing arm 13. Through the rotation of the motor 11, the swing arm 13 can drive the shell 7 to reciprocate. It should be noted that the length of the shell 7 is less than the length of the rubbing roller 4. In the initial working position, the shell 7 and the rubbing roller 4 are coaxially distributed. During operation, the left and right swing distance of the shell 7 is less than 1 / 2 of the length difference between the two, so as to prevent the material from falling from the edge position when the shell 7 swings.

[0039] The size of the feed gap 6 can be achieved by adjusting the gap between the rubbing roller 4 and the inner wall of the arc-shaped chamber 8. Extension rods are welded at both ends of the rubbing roller 4. A mounting seat 14 is provided at the end of the extension rod. A slider is provided at the lower part of the mounting seat 14. A cylinder 30 is installed on one side of the slider. When in use, the cylinder 30 can drive the mounting seat 14 to move, thereby driving the rubbing roller 4 away from or close to the shell 7, thereby changing the size of the feed gap 6. It is suitable for cleaning materials of different diameters and specifications. At the same time, when the entire cleaning operation is completed, the program is set to enable the cylinder 30 to push the rubbing roller 4 away from the shell 7. The advantage of this operation is that it can avoid the phenomenon of material getting stuck between the rubbing roller 4 and the shell 7.

[0040] When in use: Step 1: Place the material to be cleaned (i.e., bearing balls) in the lower hopper 1;

[0041] Step 2: The steel balls fall onto the distributor 2, and the rotation of the distributor 2 and the grooves 17 formed on its surface are used to control the falling speed of the materials to ensure uniform material delivery;

[0042] Step 3: The material passes through the distributor 2 and enters the conveying device. During the conveying process, the material is sprayed with cleaning oil using the spray head 3 and then continues to be conveyed to the scrubbing device;

[0043] Step 4: After the material enters the scrubbing device from the feed gap 6, the scrubbing device 5 and the rubbing roller 4 are used to rub the material so that the impurities adhering to the surface of the material are loosened or fall off, and then the material leaves the scrubbing device;

[0044] Step 5: After leaving the scrubbing device, the material enters the next conveying device, on which the cleaning oil is sprayed again to remove loose impurities on the surface of the material after scrubbing and make them fall off from the surface of the material;

[0045] Step 6: Repeat steps 4 and 5, and set the number of cycles according to the material cleaning requirements;

[0046] Step 7: After the cleaning operation is completed, the cleaned material is transported to the recycling end.

[0047] Example 2

[0048] The same as Example 1 is not repeated here, except that Fig.10 As shown, the kneading device 5 is mounted on the base 34 and kept fixed, and the rubbing roller 4 is placed in the kneading device 5. One end of the rubbing roller 4 is provided with a rotating shaft 31 extending outward, and the end of the rotating shaft 31 is connected to the motor 11 to drive the rubbing roller 4 to rotate. The side wall of the rubbing roller 4 is provided with an adjusting plate 33 located below the rotating shaft 31 and arranged horizontally. One side of the base 34 is provided with a supporting plate for maintaining the height of the rubbing roller 4. The adjusting plate 33 is slidably connected to the supporting plate. One end of the adjusting plate 33 is provided with an L-shaped baffle, and the L-shaped baffle is installed with an electric push rod 32. The electric push rod 32 pushes the adjusting plate 33 to adjust the height of the rubbing roller 4. The section plate 33 moves laterally, thereby realizing the approach of the rubbing roller 4 to or away from the kneading device 5. In this embodiment, the motor 11 and the electric push rod 32 are designed on the same side. Without affecting the rotation and horizontal movement of the rubbing roller 4, the pad material can be easily replaced and disassembled on the other side, thereby improving the efficiency of equipment maintenance and inspection. At the same time, the electric push rod 32 in this embodiment has the same function as the cylinder 30 in Example 1, and their function is to adjust the gap between the rubbing roller 4 and the kneading device 5. Other driving methods or manual adjustment methods can also be selected to complete it.
