DETAILED DESCRIPTION

[0040] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0041] Example:

[0042] See Figures 1 to 9 An embodiment of the present invention discloses a bearing cleaning device, which includes a machine tool 100, a turning structure 200, a first pushing structure 300, a second pushing structure 400, and a cleaning structure 500. The machine tool 100 is provided with a first aisle 110, a second aisle 120, and a third aisle 130 for bearings to pass through in sequence. The first pushing structure is used to push the bearings in the second aisle 120 into the turning structure 200, and the second pushing structure 400 is used to push the turned bearings in the turning structure 200 into the third aisle 130. The cleaning structure 500 can cover the first aisle 110 and the second aisle 120 at the same time and clean the bearings in the first aisle 110 and the second aisle 120 at the same time.

[0043] The bearing cleaning device disclosed in this embodiment can flip the bearing over through the cooperation of the first pushing structure 300, the second pushing structure 400 and the flipping structure 200. When the bearing passes through the first aisle 110, its first surface is cleaned, and when the bearing passes through the third aisle 130, its second surface opposite to the first surface is cleaned, thereby ensuring that all positions of the bearing can be cleaned. In addition, the cooperation of the first pushing structure 300, the second pushing structure 400 and the flipping structure 200 can realize automatic and continuous feeding of the bearing, which can improve its cleaning efficiency while ensuring that the bearing is clean.

[0044] See Figure 1 and Figure 2The machine tool 100 is provided with a first aisle 110, a second aisle 120, and a third aisle 130. The first aisle 110 and the third aisle 130 are both arranged perpendicular to the second aisle 120, and the first aisle 110 and the third aisle 130 are located on the same side of the second aisle 120. This allows the cleaning structure 500 to cover both the first aisle 110 and the third aisle 130 after being installed on the machine tool 100, thereby ensuring that the cleaning structure 500 can clean both surfaces of the bearing. The first aisle 110 is connected to the second aisle 120, and the second aisle 120 is disconnected from the third aisle 130. The flip seat 230 is located at the intersection of the extension line of the second aisle 120 and the extension line of the third aisle 130.

[0045] A first conveying structure is provided in the first aisle 110, and the first conveying structure can convey the bearings along the first aisle 110 into the second aisle 120. A second conveying structure is provided in the third aisle 130, and the second conveying structure can convey the bearings along the third aisle 130 into the next processing device of the bearing.

[0046] See Figures 1 to 4 The flip structure 200 includes a mounting base 210, a connecting shaft 220, a flip base 230, a first material stop plate 240, and a second material stop plate 250. The mounting base 210 is mounted on the machine tool 100. The flip base 230 is connected to the mounting base 210 via the connecting shaft 220, allowing the flip base 230 to rotate relative to the mounting base 210. The flip base 230 is located at the intersection of the second aisle 120 and the third aisle 130. The rotation axis of the flip base 230 is parallel to the second aisle 120. The flip structure 200 is used to flip the bearing.

[0047] The flip seat 230 includes a connecting plate 231, two clamping plates 232, two sliding plates 233, and two second elastic members 234. The connecting plate 231 is connected to the connecting shaft 220, and the connecting shaft 220 can drive the connecting plate 231 to rotate synchronously when rotating. The two clamping plates 232 are both located on the side of the connecting plate 231 facing the second aisle 120, and the two clamping plates 232 are arranged opposite each other on the connecting plate 231. The two sliding plates 233 are connected to the two clamping plates 232 in a one-to-one correspondence. The sliding direction of the sliding plates 233 is perpendicular to the axis of the connecting shaft 220, so that when the clamping plates 232 are aligned with the third aisle 130, the moving direction of the sliding plates 233 is parallel to the third aisle 130. The two second elastic members 234 are connected to the two sliding plates 233 in a one-to-one correspondence. The two ends of the second elastic member 234 are respectively connected to the clamping plate 232 and the sliding plate 233. The second elastic member 234 makes the sliding plate 233 have a tendency to move away from the third aisle 130.

[0048] The first retaining plate 240 is positioned below the tilting seat 230 and is arc-shaped. It is coaxial with the tilting seat 230. The first retaining plate 240 engages with the tilting seat 230 to prevent the bearing within it from falling out during the tilting seat 230's rotation. The second retaining plate 250 is pivotally connected to the first retaining plate 240 at one end facing the third passageway 130. The rotation axis of the second retaining plate 250 is parallel to the axis of the first retaining plate 240, and the second retaining plate 250 and the first retaining plate 240 have the same curvature. Since the bearing has already begun to move within the tilting seat 230 when it first tilts, if the first retaining plate is positioned too high, the bearing may not be able to properly enter the third passageway 130 under the propulsion of the second pushing structure 400. If the first retaining plate is positioned too low, the bearing may simply slip out of the tilting seat 230. The second retaining plate 250 effectively prevents this from occurring. In addition, the end of the first material stopper 240 facing the third aisle 130 may be aligned with or lower than the third aisle 130, while the end of the first material stopper 240 facing away from the second material stopper 250 may be higher than the third aisle 130. This can prevent the bearing from sliding off the side of the flip seat 230 facing away from the third aisle 130 when the flip seat 230 is about to complete its flipping process.

[0049] Since the second material baffle 250 needs to occupy space for movement when rotating, this causes the flip seat 230 to be unable to fit with the third aisle 130, which may cause the bearing to be unable to normally enter the third aisle 130 when the second pushing structure 400 pushes. Based on this, the present embodiment can provide a third elastic member 420 and a push block 410 for cooperating with the sliding plate 233 on the second pushing structure 400. The push block 410 is slidably connected to the second pushing structure 400, and the moving direction of the push block 410 is parallel to the third aisle 130. The two ends of the third elastic member 420 are respectively connected to the second pushing structure 400 and the push block 410. The third elastic member 420 makes the push block 410 have a tendency to move toward the third aisle 130, and the elastic force of the third elastic member 420 is greater than the elastic force of the second elastic member 234. In addition, a connecting rod 260 can be set on the second baffle plate 250, one end of the connecting rod 260 is rotatably connected to the end of the second baffle plate 250 away from the first baffle plate 240, and the other end of the connecting rod 260 is rotatably connected to the output end of the second pushing structure 400.

[0050] When the second pushing structure 400 is working, the second pushing structure 400 will first drive the second baffle plate 250 to rotate through the connecting rod 260 to prevent the second baffle plate 250 from affecting the movement of the bearing. At the same time, the pushing block 410 on the second pushing structure 400 will push the sliding plate 233 to drive the bearing to move toward the third aisle 130. When the sliding plate 233 is level with the third aisle 130, the second pushing structure 400 continues to work to push the bearing from the sliding plate 233 into the third aisle 130.

[0051] See Figure 1 、 Figure 2 and Figures 5 to 9 The first pushing structure 300 is mounted on the machine tool 100 and is connected to the flip structure 200 via the transmission structure 600. The first pushing structure 300 is located at the junction of the first aisle 110 and the second aisle 120. The working direction of the first pushing structure 300 is parallel to the second aisle 120. The first pushing structure 300 is used to push the bearing in the second aisle 120 into the flip structure 200.

[0052] The transmission structure 600 includes a control rod 610, a control ring 640, a first gear 620, and a second gear 630. The control rod 610 is connected to the first pushing structure 300. When the first pushing structure 300 is in operation, it can drive the control rod 610 to move synchronously. The outer peripheral wall of the control rod 610 is provided with a first helical surface 611. The control ring 640 is rotatably connected to the machine tool 100. The inner peripheral wall of the control ring 640 is provided with a second helical surface 642 that cooperates with the first helical surface 611, so that when the control rod 610 moves, it can drive the control ring 640 to rotate. Figure 2 and Figure 5 When the control rod 610 moves along Figure 2 When the control ring 640 moves to the right, Figure 5 When the control rod 610 is rotated in the counterclockwise direction; Figure 2 When the control ring 640 moves to the left, Figure 5 Rotate in clockwise direction.

[0053] The first gear 620 is mounted on the connecting shaft 220. The first gear 620 is coaxial with the connecting shaft 220 and can drive the connecting shaft 220 to rotate synchronously when the first gear 620 rotates. The second gear 630 is rotationally connected to the machine tool 100. The second gear 630 cooperates with the control ring 640, and the second gear 630 meshes with the first gear 620. A ratchet 641 is provided on the outer wall of the control ring 640. The inner side of the second gear 630 is provided with a mounting hole 634 and a clearance groove 631. The clearance groove 631 is connected to the mounting hole 634, and the control ring 640 rotates with the mounting hole 634. The second gear 630 is provided with a limit plate 632 and a first elastic member 633. The limit plate 632 is located in the clearance groove 631 and is rotationally connected to the second gear 630. The rotation axis of the limit plate 632 is parallel to the axis of the second gear 630. The first elastic member 633 has two ends connected to the second gear 630 and the limiting plate 632, respectively. The first elastic member 633 forces the limiting plate 632 to rotate out of the clearance slot 631. When the limiting plate 632 rotates out of the clearance slot 631, the control lever 610 rotates in the first direction, which in turn drives the second gear 630 to rotate synchronously. When the control ring 640 rotates in the second direction, the control ring 640 pushes the limiting plate 632 back into the clearance slot 631, thereby keeping the second gear 630 stationary.

[0054] Among them, see Figure 5 In this embodiment, the clockwise direction in the figure is the first direction, and the counterclockwise direction in the figure is the second direction.

[0055] In this embodiment, the first pushing structure 300 and the second pushing structure 400 can both be configured as linear reciprocating pushing structures such as electric push rods or hydraulic push rods.

[0056] The bearing cleaning device disclosed in this embodiment works as follows:

[0057] The processed bearings are put into the first aisle 110 one by one, and these bearings are moved toward the second aisle 120 in sequence under the power of the first conveying structure.

[0058] After the bearing enters the second passage 120, the first pushing structure 300 begins to operate. As the first pushing structure 300 extends, the control rod 610 moves rightward and drives the control ring 640 to rotate in the second direction. At this time, the rotation of the control ring 640 does not drive the second gear 630 to rotate. After the first pushing structure 300 pushes the bearing into the flipping structure 200, the first pushing structure 300 begins to retract. During the contraction of the first pushing structure 300, the control rod 610 moves leftward and drives the second control ring 640 to rotate in the first direction. At this time, the control ring 640 drives the second gear 630 to rotate, which in turn drives the flip seat 230 to rotate via the first gear 620 and the connecting shaft 220, thereby achieving the flipping of the bearing.

[0059] The second pushing mechanism 400 then begins to work. It first rotates the second baffle plate 250 via the connecting rod 260 to prevent the second baffle plate 250 from affecting the movement of the bearing. Simultaneously, the push block 410 on the second pushing mechanism 400 pushes the sliding plate 233, forcing the bearing to move toward the third aisle 130. When the sliding plate 233 is flush with the third aisle 130, the second pushing mechanism 400 continues to work, pushing the bearing from the sliding plate 233 into the third aisle 130. This completes the entire process of flipping the bearing and moving it from the second aisle 120 into the third aisle 130.

[0060] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
