[0037] Reference Figures 1 to 10 As shown, a bearing cleaning and oiling machine provided according to an embodiment of the present application includes a frame 100, an oiling component 200, four transfer components 300 and a loading ramp 400, and the frame 100 is provided with a rotating shaft 110.

[0038] The oiling assembly 200 includes a cleaning chamber 210, a first drying chamber 220, an oiling chamber 230 and a second drying chamber 240 arranged in sequence from top to bottom in the vertical direction. The tops of the cleaning chamber 210, the first drying chamber 220, the oiling chamber 230 and the second drying chamber 240 are all provided with a receiving channel 250, and the bottoms are all provided with a discharge channel 260. The bearings can enter the cleaning chamber 210, the first drying chamber 220, the oiling chamber 230 or the second drying chamber 240 through the receiving channel 250, and leave the cleaning chamber 210, the first drying chamber 220, the oiling chamber 230 or the second drying chamber 240 from the discharge channel 260 after cleaning, primary drying, oiling or secondary drying.

[0039] The transfer assembly 300 includes a fixed plate 310 fixed to the frame 100 and a turntable 320 coaxial with the fixed plate 310. The turntable 320 is located above the fixed plate 310 and is attached to the upper surface of the fixed plate 310. The turntable 320 is provided with a first feed hole 321, and the fixed plate 310 is provided with a second feed hole 311. The apertures of the first feed hole 321 and the second feed hole are slightly larger than the outer diameter of the bearing to be oiled. The second feed hole 311 is correspondingly connected to the top of the receiving channel 250, and three of the second feed holes 311 are correspondingly provided in the discharge channel 2 60, in other words, a transfer assembly 300 is respectively arranged above the cleaning bin 210, the first drying bin 220, the oiling bin 230 and the second drying bin 240, and the second discharge hole 311 of the fixed plate 310 in the transfer assembly 300 corresponds to and is connected with the receiving channels 250 of the four bin bodies in the vertical direction, and the three transfer assemblies 300 below also correspond to the discharge channel 260 of the cleaning bin 210, the discharge channel 260 of the first drying bin 220 and the discharge channel 260 of the oiling bin 230, respectively.

[0040] The turntables 320 of the four transfer assemblies 300 are each connected to the rotating shaft 110, which is connected to a drive motor 330. The drive motor 330 drives the rotating shaft 110 to rotate the turntables 320, thereby connecting the cleaning chamber 210, the first drying chamber 220, the oiling chamber 230, and the second drying chamber 240 through the first and second discharge holes 321 and 311. A loading ramp 400 is positioned toward the topmost turntable 320. The loading ramp 400 and the second discharge hole 311 of the topmost fixed plate 310 are spaced apart along the circumference of the fixed plate 310. The loading ramp 400 is arranged at an angle, with the end closest to the turntable 320 tilting downward. The end of the loading channel away from the turntable 320 is connected to an external loading device.

[0041] It can be understood that in the initial state, the loading ramp 400 is aligned with the first discharge hole 321 of the top turntable 320, and the angle between the first discharge hole 321 of the turntable 320 and the second discharge hole 311 of the fixed plate 310 in each transfer component 300 (in this embodiment, the angle between the first discharge hole 321 and the second discharge hole 311 is defined as the central angle between the line connecting the first discharge hole 321 to the center of the turntable 320 and the line connecting the second discharge hole 311 to the center of the turntable 320. Other characteristic angles appearing later may also refer to this definition. It is specially explained here to avoid misunderstanding) is equal and equal to the angle between the loading ramp 400 and the second discharge hole 311. After the loading ramp 400 transfers the bearing to be oiled to the first discharge hole 321 of the uppermost turntable 320, since the turntable 320 is located above the fixed plate 310, the fixed plate 310 can support the bearing in the first discharge hole 321 below the bearing, and the driving motor 330 drives the rotating shaft 110 to drive the uppermost turntable 320 to rotate, and the bearing rotates with the turntable 320 in the first discharge hole 321. When the first discharge hole 321 and the second discharge hole 311 of the uppermost transfer assembly 300 are aligned and connected, the lower The first discharge holes 321 and the second discharge holes 311 of the three transfer components 300 on the side are also aligned and connected. At this time, the three transfer components 300 below are respectively connected to the corresponding discharge channels 260, so that the cleaning bin 210, the first drying bin 220, the oiling bin 230 and the second drying bin 240 are connected in sequence from top to bottom. The bearing passes through the cleaning bin 210, the first drying bin 220, the oiling bin 230 and the second drying bin 240 in sequence from the first discharge hole 321 at the top, thereby realizing the bearing oiling step.

[0042] By setting up the oiling component 200 and the transfer component 300, individual bearings are allowed to enter the cleaning chamber 210, the first drying chamber 220, the oiling chamber 230 and the second drying chamber 240 one by one to complete the oiling treatment, and then be discharged through the discharge channel 260, thereby realizing the automated transportation of the bearing oiling treatment, effectively improving the convenience of the bearing oiling treatment, improving the production efficiency of the bearings, and reducing the labor cost.

[0043] Reference Figure 3 and Figure 4As shown, it should be supplemented that a gear set is provided between the rotating shaft 110 and the drive motor 330, and the gear set includes a first gear 340 fixed to the rotating shaft 110 and a second gear 350 fixed to the output shaft of the drive motor 330, and the second gear 350 includes a first sector gear 351 and a second sector gear 352, and the first sector gear 351 and the second sector gear 352 are arranged around the circumference of the output shaft and the first sector gear 351 is located above the second sector gear 352, and the central angle of the first sector gear 351 is equal to the angle between the loading ramp 400 and the second unloading hole 311, and the sum of the central angles of the first sector gear 351 and the second sector gear 352 is equal to 360°, and both the first sector gear 351 and the second sector gear 352 can engage with the first gear 340.

[0044] When the first sector gear 351 and the first gear 340 engage, the bearing rotates along with the turntable 320 in the first discharge opening 321. When the second sector gear 352 and the first gear 340 engage, the bearing is discharged through the discharge channel 260 of the second drying chamber 240, and the turntables 320 of the four transfer assemblies 300 return to their original positions. By providing the first sector gear 351 and the second sector gear 352, the rotation angle of the transfer assemblies 300 can be precisely controlled, ensuring alignment between the first discharge opening 321 and the second discharge opening 311, effectively improving the control accuracy of the transfer assemblies 300.

[0045] Optionally, the gear ratio of the first gear 340 to the first sector gear 351 is greater than the gear ratio of the first gear 340 to the second sector gear 352. This ensures that the rotational speed of the first gear 340 when the first sector gear 351 is meshed with the first gear 340 is lower than the rotational speed of the first gear 340 when the second sector gear 352 is meshed with the first gear 340. This allows the top transfer assembly 300 to smoothly transport the bearings and quickly return them to their original position, further improving bearing production efficiency.

[0046] Reference Figure 1 and Figure 5 As shown, it can be understood that the frame 100 includes two cross-shaped connecting frames 120 and four frames 130, and the two ends of the frame 130 are respectively connected to an axis of the two connecting frames 120, and the rotating shaft 110 is rotatably connected to the center of the two connecting frames 120. The bottom end of the rotating shaft 110 passes through the lower connecting frame 120 and is connected to the drive motor 330 for transmission. The fixed plate 310 is fixed between the four frames 130, and the cleaning chamber 210, the first drying chamber 220, the oiling chamber 230 and the second drying chamber 240 are respectively connected to the four frames 130.

[0047] Connecting the first drying chamber 220, the oiling chamber 230 and the second drying chamber 240 to the four frames 130 respectively can optimize the stress distribution of the all-in-one machine, make the center of gravity of the all-in-one machine fall on the rotating shaft 110, avoid excessive load on a single frame 130, and effectively improve the structural stability of the all-in-one machine.

[0048] It should be noted that since the cleaning bin 210, the first drying bin 220, the oiling bin 230 and the second drying bin 240 are respectively connected to the four frames 130, at this time, the first drying bin 220, the oiling bin 230 and the second drying bin 240 are arranged equidistantly along the circumference of the fixed disk 310, and the second discharge hole 311 of the fixed disk 310 corresponds to the position of the receiving channel 250 of the first drying bin 220, the oiling bin 230 and the second drying bin 240. At this time, the discharge channel 260 of the first drying bin 220, the oiling bin 230 and the second drying bin 240 will have a certain bending angle to ensure that the discharge channel 260 corresponds to the position of the second discharge hole 311.

[0049] Reference Figure 2 and Figure 5 As shown, it is understood that the bearing cleaning and oiling machine also includes a positioning assembly 500. The positioning assembly 500 is installed on the uppermost turntable 320 and is located on one side of the loading ramp 400 to position the bearing to be oiled. Optionally, the positioning assembly 500 can be a trough structure, a block structure, etc. provided on the turntable 320, and will not be described in detail here.

[0050] By providing the positioning assembly 500 , when the bearing enters the turntable 320 through the loading ramp 400 , the positioning assembly 500 can position the bearing so that the bearing falls accurately into the first discharge hole 321 , further improving the working stability of the transfer assembly 300 .

[0051] Furthermore, there are multiple first discharge holes 321, and the multiple first discharge holes 321 are arranged at circumferential intervals along the turntable 320. The angle between two adjacent first discharge holes 321 is equal to the angle between the loading ramp 400 and the corresponding second discharge hole 311. The positioning assembly 500 is arranged in a one-to-one correspondence with the first discharge hole 321 of the uppermost turntable 320.

[0052] Multiple first feed holes 321 are provided, and the angle between two adjacent first feed holes 321 is equal to the angle between the loading ramp 400 and the corresponding second feed hole 311. When one of the first feed holes 321 of the top transfer assembly 300 receives a bearing delivered from the loading ramp 400 and transfers the bearing to the second feed hole 311, the other unused first feed hole 321 also synchronously rotates to the feed ramp 700 and receives a new bearing. As the rotating shaft 110 continues to rotate, the multiple first feed holes 321 of the upper transfer assembly 300 sequentially transfer new bearings, while the other transfer assemblies 300 ensure that the new bearings can pass through the cleaning chamber 210, the first drying chamber 220, the oiling chamber 230, and the second drying chamber 240 in sequence, achieving continuous and rapid transmission of bearings, reducing reset time, and significantly improving the working efficiency of the all-in-one machine.

[0053] It should be noted that when a plurality of first discharge holes 321 are provided, a plurality of first sector gears 351 may be provided correspondingly to ensure the working accuracy of the transfer assembly 300 .

[0054] Reference Figure 1 and Figure 2 As shown, it can be understood that the frame 100 is connected to a material discharge ramp 700 , and the material discharge ramp 700 is connected to the discharge channel 260 of the second drying chamber 240 .

[0055] Reference Figures 6 to 8 As shown, it can be understood that the positioning assembly 500 includes a positioning plate 510, a telescopic rod 520 and a spring 530. The telescopic rod 520 can be extended and retracted along the radial direction of the turntable 320. The turntable 320 is provided with a baffle 322. One end of the telescopic rod 520 is fixed to the baffle 322 on the turntable 320, and the other end is connected to the positioning plate 510. The spring 530 is sleeved on the telescopic rod 520, and the two ends of the spring 530 are respectively in contact with the positioning plate 510 and the baffle 322. The positioning plate 510 is located above the first discharge hole 321, and the positioning plate 510 is provided with an arc-shaped positioning groove on the side facing the loading ramp 400.

[0056] By providing the positioning plate 510, telescopic rod 520, and spring 530, when the bearing slides from the loading ramp 400 to the turntable 320, it impacts the positioning plate 510, which in turn compresses the spring 530. After the bearing falls into the first discharge hole 321, the positioning plate 510 is positioned by the wall of the positioning groove and presses against the bearing, preventing the bearing from shaking and falling out of the first discharge hole 321. This effectively improves the positioning accuracy of the bearing and enhances the transportation stability of the transfer assembly 300. Furthermore, the spring 530 absorbs the impact of the bearing on the positioning plate 510, reducing the recoil force on the bearing and ensuring the bearing's quality.

[0057] Reference Figure 8As shown, it can be understood that the bearing cleaning and oiling machine also includes an isolation component 600, which includes an L-shaped plate 610 and a torsion spring 620. The L-shaped plate 610 is rotatably connected to one end of the loading ramp 400 close to the turntable 320. One side of the L-shaped plate 610 is located between the exit of the loading ramp 400 and the turntable 320, and the other side is located above the loading ramp. The two ends of the torsion spring 620 are respectively fixed to the L-shaped plate 610 and the loading ramp 400.

[0058] By setting up the L-shaped plate 610, when the bearing is transferred from the loading ramp 400 to the turntable 320, the bearing impacts the L-shaped plate 610, causing the L-shaped plate 610 to rotate. After the rotation, the L-shaped plate 610, which was originally above the loading ramp, rotates to between the exit of the loading ramp 400 and the turntable 320, thereby isolating the bearing at the rear. The torsion spring 620 can reset the L-shaped plate 610, realizing continuous and sequential loading of the bearings, effectively improving the orderliness of the all-in-one machine.

[0059] Furthermore, the topmost turntable 320 is provided with an annular flange 323, and the flange 323 is provided with a notch for the bearing to pass through, and the notch is located between the positioning assembly 500 and the isolation assembly 600. When there are multiple positioning assemblies 500, the notches are provided in a one-to-one correspondence with the positioning assemblies 500.

[0060] By providing a flange 323 with a notch, the flange 323 can limit the bearing when the bearing is transferred from the loading ramp 400 to the turntable 320, preventing the bearing from running off track, and effectively improving the smoothness of the bearing's transition between the loading ramp 400 and the turntable 320.

[0061] Reference Figure 9 As shown, it can be understood that the uppermost fixed plate 310 is provided with a card slot 312 , and the card slot 312 is engaged with the loading ramp 400 .

[0062] Since the loading ramp 400 is tilted and corresponds to the turntable 320, the provision of the latching slot 312 allows the loading ramp 400 to be avoided, thereby preventing the loading ramp 400 from interfering with the uppermost fixed plate 310 and affecting the installation of the loading ramp 400. On the other hand, the latching of the loading ramp 400 with the latching slot 312 can effectively improve the installation stability of the loading ramp 400.

[0063] Furthermore, the fixed disk 310 is provided with an annular slide rail 313 , and the rotating disk 320 is connected to a slider 324 slidably connected to the slide rail 313 . There are at least two sliders 324 , and the at least two sliders 324 are spaced apart along the circumference of the slide rail 313 .

[0064] By providing the slide rail 313 and the slider 324 , the slider 324 guides the turntable 320 to rotate through the slide rail 313 , thereby effectively improving the rotation stability of the turntable 320 , improving the installation stability of the turntable 320 , and improving the overall structural tightness of the transfer assembly 300 .

[0065] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
