Description

Technical Field

[0001] This utility model relates to the field of bearing ball processing technology, and in particular to a cylindrical polishing device. Background Technology

[0002] Bearings are indispensable core components in modern mechanical equipment. Their core functions are to support rotating bodies, reduce the coefficient of friction, and ensure rotational accuracy. From automobile wheel hubs to aerospace engines, from machine tool spindles to precision instruments, bearings convert sliding friction into rolling friction, enabling mechanical components to operate efficiently and smoothly. The balls are the core component of ball bearings. By rolling between the inner and outer raceways, they convert sliding friction into rolling friction, thus significantly reducing energy loss. During manufacturing, balls may develop scratches, pits, and microcracks. These defects can become stress concentration points, causing the balls to break under external forces during use, severely affecting bearing life. Therefore, polishing is necessary for bearing balls to ensure their precision and lifespan.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] See Figures 1-7 This utility model discloses a cylindrical polishing device for polishing bearing balls, including a support panel 1, a polishing box 2, a first transmission component 3, a closed door 4, a support structure 8, and a sealing component 5.

[0021] See Figure 1 and Figure 6As shown, the polishing box 2 is rotatably mounted on the support structure 8. Specifically, the support structure 8 includes a top frame 81, longitudinal connecting rods 82, and a bottom frame 83. There are four longitudinal connecting rods 82. The top frame 81 is formed by four steel rods enclosing each other end to end, and the bottom frame 83 is also formed by four steel rods enclosing each other end to end. The longitudinal connecting rods 82 are located between the top frame 81 and the bottom frame 83 to connect them. The steel rods have the advantages of high strength and good stability. An installation block 84 is provided between two adjacent longitudinal connecting rods 82 on the support structure 8. A support bearing 85 is provided on the installation block 84. A drive shaft 86 is rotatably connected inside the support bearing 85. The other end of the drive shaft 86 is fixedly connected to the polishing box 2. Specifically, the polishing box 2 is located between the top frame 81 and the bottom frame 83. The support structure 8 provides an installation area for the polishing box 2, and the support bearing 85 and the drive shaft 86 ensure the smoothness and reliability of the rotation process of the polishing box 2.

[0022] See Figure 2 , Figure 3 and Figure 7 As shown, in this embodiment, the interior of the polishing box 2 is hollow, forming a receiving space 21 for accommodating bearing balls. An opening 22 is provided on one side wall of the polishing box 2. The polishing box 2 is cylindrical and made of stainless steel, which has good wear resistance, corrosion resistance and sealing performance, and can withstand the friction and impact generated during the polishing process. As a polishing container for bearing balls, the polishing box 2 provides a stable polishing environment for the balls. Multiple polishing plates 9 are arranged at intervals along its circumference inside the polishing box 2. The bearing balls are polished by the polishing plates 9. The multiple polishing plates 9 can increase the contact area with the bearing balls and improve the polishing efficiency and quality.

[0023] See Figure 1 and Figure 2 As shown, in this embodiment, the sealing door 4 is detachably installed at the opening 22 of the polishing box 2 to either close or expose the polishing box 2. When the sealing door 4 is located at the opening 22 of the polishing box 2, the polishing box 2 is closed; when the sealing door 4 is at the opening 22 of the polishing box 2, the polishing box 2 is exposed. Closing or exposing the polishing box 2 facilitates the installation and removal of bearing balls. During the polishing process, the sealing door 4 prevents polishing debris from overflowing, ensuring a clean working environment. The material of the sealing door 4 is the same as that of the polishing box 2, which is stainless steel, to ensure its strength and sealing performance. Specifically, the closed door 4 includes a closed plate 41, a locking block 42, and a locking groove 43. Multiple locking blocks 42 are spaced apart along the outer periphery of the closed plate 41, and multiple locking grooves 43 are spaced apart along the outer periphery of the opening 22. The number of locking grooves 43 and locking blocks 42 are the same and they are locked in one-to-one. Fasteners 431 are inserted into the locking blocks 42 and locking grooves 43. The closed plate 41 is also provided with a push-pull handle 411 for easy operation.

[0024] Specifically, one end of the slot 43 is open, and its cross-section is U-shaped. The push-pull handle 411 rotates the closing plate 41 to make the locking block 42 rotate from the opening of the slot 43 into the slot 43 and abut against the other end of the slot 43 for fixation. The corresponding positions of the locking block 42 and the slot 43 are provided with slots. The fastener 431 is set through the slots of the locking block 42 and the slot 43. In this embodiment, the fastener 431 is a screw. Through the locking of the locking block 42 and the slot 43 and the fixation of the fastener 431, the closed door 4 and the opening 22 of the polishing box 2 are tightly connected. The connection method is simple and reliable, which facilitates the installation and disassembly of the closed door 4, and at the same time ensures the tightness of the seal and prevents the debris from overflowing during the polishing process.

[0025] See Figure 1 As shown, the support panel 1 is located on the side of the sealing assembly 5 away from the polishing box 2. The support panel 1 is set along the outer edge of the top frame 81, the longitudinal connecting rod 82 and the bottom frame 83. The support panel 1 is also made of stainless steel, which has good wear resistance, corrosion resistance and sealing performance. The support panel 1 is welded to the outer edge of the top frame 81, the longitudinal connecting rod 82 and the bottom frame 83 to ensure its overall firmness.

[0026] See Figure 1 and Figure 5 As shown, in this embodiment, a drive assembly 7 is also included. A drive member 71 is disposed on the bottom frame 83. The drive assembly 7 includes a drive member 71 and a second transmission member 72. The output end of the drive member 71 is connected to the second transmission member 72. The drive member 71 includes a drive motor 711 and a gearbox 712. The output end of the drive motor 711 is connected to the gearbox 712, and the output end of the gearbox 712 is connected to the second transmission member 72. A second clearance groove 12 for avoiding the second transmission member 72 is provided on the support panel 1. The drive assembly 7 provides power for the rotation of the polishing box 2 and drives the second transmission member 72 to rotate. The speed of the drive motor 711 is stable and easy to control, which can meet the requirements of different polishing processes.

[0027] See Figure 5 As shown, in this embodiment, the first transmission component 3 is fixedly arranged along the outer periphery of the opening 22. Specifically, the first transmission component 3 is fixedly connected to the side wall of the polishing box 2 by screws. The first transmission component 3 can drive the polishing box 2 to rotate. The support panel 1 is provided with a first clearance groove 11 for avoiding the closed door 4. The first transmission component 3 and the second transmission component 72 are connected in a transmission manner. When the drive motor 711 drives the second transmission component 72 to rotate, it drives the first transmission component 3 to rotate, thereby driving the polishing box 2 to rotate as a whole for polishing.

[0028] More specifically, in this embodiment, both the first transmission member 3 and the second transmission member 72 are gears. The first transmission member 3 and the second transmission member 72 are meshed together, and the power of the driving member 71 is transmitted to the first transmission member 3 through the second transmission member 72, thereby realizing the transmission and conversion of power. The gear meshing transmission method has the advantages of high transmission accuracy, high efficiency and smooth operation, which can ensure the stable operation of the polishing device.

[0029] See Figure 5 As shown, in this embodiment, a flange 6 is provided between the first transmission component 3 and the sealing component 5. The flange 6 is fixedly connected to the support panel 1. The first transmission component 3 and the sealing component 5 can rotate circumferentially relative to the flange 6. It should also be noted that, from the axial direction of the ring body 51 outward, a locking block 42, a locking groove 43, a second lip plate 53, a first lip plate 52, a flange 6, and the first transmission component 3 are arranged in sequence. This design ensures that when the drive motor 711 drives the first transmission component 3 to rotate, it will also drive the sealing component 5 to rotate synchronously, while the flange 6 does not rotate, achieving a dynamic sealing effect at the opening 22 of the polishing box 2.

[0030] See Figure 4 As shown, in this embodiment, the sealing component 5 is fixedly arranged along the outer circumference of the opening 22 of the polishing box 2. The sealing component 5 is used to separate the first transmission component 3 from the opening 22. The sealing component 5 includes a ring body 51, a first lip plate 52 and a second lip plate 53. The first lip plate 52 is disposed at one end of the ring body 51, and is bent away from the axis of the ring body 51 and then bent back towards the axis of the ring body 51. The second lip plate 53 is disposed at the other end of the ring body 51 and is bent towards the axis of the ring body 51. The first lip plate 52 abuts against the outer peripheral surface of the first clearance groove 11, the outer surface of the ring body 51 contacts the outer surface of the flange 6, and the second lip plate 53 is fixedly connected to the polishing box 2. Specifically, the fixed connection between the second lip plate 53 and the polishing box 2 is by welding or screw connection, which is not specifically limited here. This design separates the first transmission component 3 from the opening 22, preventing polishing debris from entering the first transmission component 3 and the drive assembly 7, thus protecting the equipment safety. At the same time, the sealing assembly 5 can also reduce the entry of external dust and impurities into the first transmission component 3. Moreover, the design of the first lip plate 52 and the second lip plate 53 increases the sealing effect, effectively preventing the leakage and entry of debris and impurities, and improving the reliability and service life of the equipment.

[0031] In this embodiment, it should also be noted that the second lip plate 53 is provided with a third clearance groove 531 for avoiding the card slot 43, which provides space for the installation of the card slot 43.

[0032] Specific implementation steps: First, the bearing balls are inserted into the polishing box 2 through the opening 22. The closed door 4 is closed by the engagement of the locking block 42 and the locking slot 43 and the fixation of the fastener 431 to ensure its airtightness. The driving component 71 is driven, which drives the second transmission component 72 to rotate. The second transmission component 72 drives the first transmission component 3 to rotate. The first transmission component 3 drives the polishing box 2 to rotate on the support structure 8. At the same time, the first transmission component 3 also drives the sealing component 5 and the closed door 4 to rotate to ensure its airtightness. During the rotation of the polishing box 2, the polishing plate 9 inside rubs against the bearing balls to achieve polishing treatment of the balls. After polishing is completed, the closed door 4 is opened and the bearing balls are taken out.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
