One end of the first left-right moving cylinder 53 is installed on the side of the first slide rail 51 and is used to drive the first slide table 52 to move left and right.

[0018] Reference Figure 2 The flipping feeding assembly 6 includes a worktable 61, a second slide rail 62, a second slide table 63, a second left-right moving cylinder 64, a second front-back pushing cylinder 65, a second transfer plate 66, a cam divider 67, a flipping frame 68, and a bidirectional cylinder 69. The worktable 61 and the cam divider 67 are both fixed to the base 1. The second slide rail 62 is fixed to the base 1. The second slide table 63 is slidably connected to the second slide rail 62. One end of the second left-right moving cylinder 64 is fixed to the second slide rail 62 and is used to drive the second slide table 63 to move. The second transfer plate 66 is slidably connected to the second slide table 63. The second front-back pushing cylinder 65 is fixed to the second slide table 63 and is used to drive the second transfer plate 66 to move. 6 is set on the top of the workbench 61. The surface of the workbench 61 has a notch. The flipping frame 68 is set in the notch. The flipping frame 68 includes a side frame 681 and a top plate 682 and a bottom plate 683 fixed on the side frame 681. The bottom plate 683 is flush with the surface of the workbench 61. After the flipping frame 68 is flipped, the top plate 682 can also be flush with the surface of the workbench 61. The cam divider 67 drives the flipping frame 68 to rotate. The bidirectional cylinder 69 is fixed on the flipping frame 68. The piston rod end of the bidirectional cylinder 69 is fixed with a connecting rod 691. The side of the connecting rod 691 is fixed with a pressure block 692. The surfaces of the top plate 682 and the bottom plate 683 are both provided with relief grooves that are adapted to the pressure block 692. In order to avoid damaging the plane bearing, a rubber pad is fixed on the surface of the pressure block 692. The flipping feeding assembly 6 also includes a feeding cylinder 7, which is fixed on the base 1, and a push block 71 is fixed to the end of the piston rod of the feeding cylinder 7. The push block 71 is set corresponding to the bearing track 2.
[0019] Reference Figure 1 The machine housing is provided with a feed inlet and a discharge outlet at the ends of the two bearing rails 2 respectively. A receiving platform 8 is provided at the feed inlet. A feeding cylinder 9 is fixed on one side of the receiving platform 8. The receiving platform 8 can be used to connect to the feeding conveyor belt, which is convenient for connecting with different production lines.
[0020] The implementation principle of the self-locking snap-fit type flat bearing batch cleaning device in this application is as follows: The feeding cylinder 9 pushes the flat bearings on the receiving platform 8 into the bearing track 2 on one side in sequence, and the material transfer component 5 on that side transfers the flat bearings to the flipping feeding component 6. When the material transfer component 5 is working, the first left and right moving cylinder 53 pulls the first material transfer plate 55 to move the flat bearing body one position to the left. Then the first front and rear pushing cylinder 54 pushes the first material transfer plate 55 to lock the flat bearing. The first left and right moving cylinder 53 resets. The above actions are repeated in sequence, which can drive the flat bearings through the bearing track 2 on that side one by one. During this process, the lifting cylinder 41 in the cleaning component 4 drives the support frame 42 to move downward, so that the flushing head 43 is close to the flat bearing. The convex ring cavity 433 on the flushing head 43 extends into the middle of the flat bearing. The water spray holes 4331 on the periphery of the convex ring cavity 433 can rinse the roller needle holder in the radial direction. The bottom of the water storage pan 432 also cleans the flat part of the flat bearing. When the flat bearing passes through the bearing track 2, it has to undergo multiple spray cleaning. After the planar bearing enters the flipping feeding assembly 6, the second transfer plate 66 transfers the planar bearing to the flipping frame 68. The bidirectional cylinder 69 works to clamp the planar bearing through the pressure block 692. After that, the cam divider 67 drives the flipping frame 68 to rotate, which can drive the planar bearing to flip over. After the planar bearing flips over, the second transfer plate 66 transfers it to the bearing track 2 on the other side. Then, the feeding cylinder 7 pushes the planar bearing onto the bearing track 2. The above cleaning action is repeated. The whole process has a long cleaning time but a good cleaning effect.
[0021] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
