Through the coordinated use of structures such as the bottom plate 1, the pickling tank 2, the cleaning tank 3, the mounting plate 5, the gear 7, the sleeve 9, the rack 12, the block 13 and the conveyor belt 20, the bearing can be transported after being placed in the placement screen frame 11, and the pickling, cleaning and unloading and collection work can be automatically completed during the transportation process, which saves time and labor, and has a high degree of automation, avoiding the problem that the bearing parts to be pickled need to be added to the placement screen frame 11 after the pickling, flushing and unloading of the bearing inside the placement screen frame 11 are completed, thereby improving the pickling efficiency of the bearing parts.

[0031] Two support frames 14 are fixedly connected to the two support plates 4, and the bottoms of the two support frames 14 are fixedly connected to the top of the base plate 1. The two sides of the cleaning pool 3 are respectively fixedly connected with a water inlet hose 15 and a drainage hose 16. The water inlet hose 15 and the drainage hose 16 are each provided with a valve 17. Through the arrangement of the water inlet hose 15, the drainage hose 16 and the valve 17, when clean water is used to clean the pickled bearings, clean water can be transported to the inside of the cleaning pool 3 again through the external water pump and the water inlet hose 15, and discharged through the drainage hose 16, thereby realizing the circulation of water source inside the clean water pool, avoiding the accumulation of a large amount of pickling liquid inside the cleaning pool 3 during the bearing cleaning process, which reduces the cleaning effect of the bearings.

[0032] The conveying assembly includes two conveying rollers 18 and a motor 19. The two conveying rollers 18 are rotatably connected between the opposite sides of the two support plates 4. A conveyor belt 20 is transmission-connected between the outer surfaces of the two conveying rollers 18. Several mounting plates 5 are fixedly connected to the outer surface of the conveyor belt 20. The motor 19 is fixedly mounted on one of the support plates 4, and the output end of the motor 19 is fixedly connected to one end of one of the conveying rollers 18.

[0033] The guide assembly includes a guide rod 21 , which is fixedly connected to the mounting plate 5 and movably connected to the connecting plate 8 .

[0034] The buffer assembly includes two dampers 22 fixedly connected to the top of the base plate 1, and the top ends of the two dampers 22 are fixedly connected to a grid plate 23. The outer surface of the damper 22 is sleeved with a spring 24. Through the setting of the buffer assembly, when the bearing is pickled and cleaned and is dropped and unloaded, the dropped bearing can be buffered, thereby reducing the damage to the bearing when it falls, thereby ensuring the quality of the bearing after processing.

[0035] Working principle: When in use, first place a collection frame for collecting bearings on the downward inclined end of the grid plate 23, add a proper amount of pickling liquid into the pickling tank 2, connect one end of the water inlet hose 15 with the water delivery end of the existing external water pump, open the corresponding valve 17 to add a proper amount of clean water into the cleaning tank 3, and then place the bearings to be pickled in the placement net frame 11 above the pickling tank 2 and away from the side of the cleaning tank 3, and start the motor 19 to drive one of the conveying rollers 18 to rotate. Under the cooperation of the other conveying roller 18, the conveyor belt 20 can drive several mounting plates 5, reciprocating screw rods 6, guide rods 21, sleeves 9 and placement net frames 11 to rotate synchronously, and at the same time make the placed bearings move synchronously. In the process of movement, the bearings to be pickled can be continuously placed in the subsequent placement net frames 11.

[0036] When the conveyor belt 20 drives the mounting plate 5, gear 7, placement screen frame 11 and the placed bearings and other structures to move synchronously, under the cooperation of the rack 12 on the far left, when it meshes with the corresponding gear 7, it drives the gear 7 to rotate, and the gear 7 drives the corresponding reciprocating screw 6 to rotate. Under the guiding and limiting action of the guide rod 21, the connecting plate 8 can drive the sleeve 9, the bracket 10, the placement screen frame 11 and the bearing to move synchronously along the axial direction of the reciprocating screw 6, so that the bearing moves down to the inside of the pickling tank 2 for pickling work, and in the process of continuing to move, under the cooperation of the subsequent multiple racks 12, the corresponding placement screen frame 11 can drive the bearing to move out from the inside of the pickling tank 2 and move down again to the inside of the cleaning tank 3. After the pickling liquid attached to it is cleaned, it can be moved up again and removed from the inside of the cleaning tank 3, realizing the automatic downward pickling, removal and cleaning and removal work;

[0037] When the bearing is pickled and cleaned, and removed from the cleaning tank 3, in the process of rotating with the conveyor belt 20, when it moves to one end of the conveyor belt 20 so that its mounting plate 5 and the placement screen frame 11 and other structures rotate synchronously and move upward in a circular manner, the placement screen frame 11 is continuously rotated, and after reaching a certain angle, the internal block 13 can no longer prevent the bearing from falling, and the bearing can be separated from the placement screen frame 11 and fall onto the mesh plate 23, impacting it. Under the contraction and squeezing action of the damper 22 and the spring 24, the impact force generated when the bearing falls can be absorbed and cushioned, thereby reducing the damage suffered by the bearing when it falls, and the bearing can be rolled to the inside of the collection frame for collection under the action of gravity.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
