[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 9As shown, a bearing ring cleaning device includes a chassis 1, a conveyor belt 2 is arranged above the chassis 1, and several groups of fixing mechanisms are installed at the bottom of the conveyor belt 2. The conveyor belt 2 is a synchronous belt, which is driven to move by a driving gear installed above the chassis 1. Each group of fixing mechanisms includes several fixing members 3, and a mounting plate 13 is installed on the rearmost fixing member 3, and a linkage rod 14 is movably installed on the mounting plate 13. Multiple groups of fixing mechanisms can act on the support platform 6 in turn to complete the cleaning of their respective bearing rings 41. A nozzle 4, a cleaning strip 5 and a positioning frame 18 are arranged in the chassis 1 along the moving direction of the conveyor belt 2. The nozzle 4 is installed on the front and rear side walls of the chassis 1, and the nozzle 4 is arranged obliquely, and the nozzles 4 on both sides are inclined in opposite directions. The inclined nozzle 4 allows the cleaning liquid to be sprayed toward the bearing ring 41 in an inclined direction, thereby driving the bearing ring 41 to rotate, so that the entire bearing ring 41 is rinsed. The cleaning strip 5 and the positioning frame 18 are installed on the rear side wall. The positioning frame 18 is located below the cleaning strip 5. A mounting rod 19 is installed in the positioning frame 18. The front end of the mounting rod 19 is connected to the support platform 6. A number of cleaning blocks 7 are installed on the support platform 6. A guide groove 22 is provided in the support platform 6. The guide groove 22 is inclined. The height of the left end of the guide groove 22 is lower than that of the right end. The right end of the guide groove 22 is connected to the right side wall of the support platform 6. A push rod 21 is movably installed at the left end of the guide groove 22. A boss 20 is provided on the side of the positioning frame 18 close to the support platform 6. The thickness of the boss 20 gradually decreases from left to right.

[0025] The linkage rod 14 can enter the guide groove 22, drive the support platform 6 to rise and move with the fixing member 3. Since the bearing ring 41 is in contact with the cleaning strip 5 and rotates, the cleaning block 7 can clean the lower end surface of the bearing ring 41, and the cleaning strip 5 can clean the outer periphery of the bearing ring 41.

[0026] The boss 20 can act on the push rod 21, thereby pushing the linkage rod 14 out of the guide groove 22, so that the linkage rod 14 no longer acts on the support platform 6, and the support platform 6 can return to its original position for cleaning the bearing ring 41 on the next set of fixing mechanisms. The linkage rod 14 can also continue to move with the fixing mechanism without being hindered.

[0027] Furthermore, a through hole 16 is provided on the mounting plate 13, and the linkage rod 14 is arranged through the through hole 16. The rear end of the through hole 16 is connected to a baffle 15. A spring 17 is sleeved on the through hole 16. One end of the spring 17 is connected to the rear side of the mounting plate 13, and the other end of the spring 17 is connected to the front end of the baffle 15. In the normal state, the linkage rod 14 partially passes through the mounting plate 13 under the action of the spring 17, and can be inserted into the guide groove 22 to drive the support platform 6 to move. When the top rod 21 is extended into the guide groove 22 again under the action of the boss 20, it can push the linkage rod 14, so that the linkage rod 14 is retracted into the through hole 16, and the linkage rod 14 is also disengaged from the guide groove 22. At this time, the linkage rod 14 can no longer drive the support platform 6 to move.

[0028] Furthermore, a mounting groove 23 is provided in the support platform 6 at a position on the side of the guide groove 22, and a stopper 26 is connected to the top rod 21. The stopper 26 is located in the mounting groove 23, and a spring 25 is connected to the rear side of the stopper 26. The other end of the spring 25 is connected to the rear side wall of the mounting groove 23.

[0029] Furthermore, a guide rod 24 is arranged in the installation groove 1 23 , and the guide rod 24 passes through the stopper 26 . A sealing block 27 is installed at the front end of the installation groove 1 23 , and a fixing hole 28 for inserting the guide rod 24 is opened on the sealing block 27 .

[0030] Under the action of the second spring 25, a part of the push rod 21 extends out of the guide groove 22, and at this time, the push rod 21 and the linkage rod 14 can both be in the guide groove 22. When the boss 20 acts on the part of the push rod 21 extending out of the guide groove 22, the push rod 21 is completely pushed into the guide groove 22, and at this time, the push rod 21 acts on the linkage rod 14 to push the linkage rod 14 out of the guide groove 22, so that the linkage rod 14 no longer acts on the support platform 6.

[0031] Further, the positioning frame 18 is provided with an intermediate block 29, two transverse slide grooves 31 and two vertical slide grooves 32 are formed between the positioning frame 18 and the intermediate block 29, the two vertical slide grooves 32 are respectively located at the two ends of the transverse slide groove 31, the two transverse slide grooves 31 and the two vertical slide grooves 32 are connected, the mounting rod 19 is located between the positioning frame 18 and the intermediate block 29, two limit blocks 38 are connected to the mounting rod 19, the two limit blocks 38 are respectively located at the front and rear sides of the positioning frame 18, the two limit blocks 38 are pressed against the positioning frame 18 to limit the mounting rod 19, the rear side of the positioning frame 18 is connected with a fixed plate 39, the rear side of the intermediate block 29 is connected with a transverse plate 40, the connecting plate 30 is connected between the fixed plate 39 and the transverse plate 40, and a reset mechanism is provided at the lower part of the positioning frame 18. The transverse slide groove 31 and the vertical slide groove 32 are connected to form an annular slide groove, which is used to guide the movement of the mounting rod 19, thereby guiding the moving direction of the support platform 6.

[0032] Furthermore, a second mounting groove 33 is provided in the positioning frame 18, and the second mounting groove 33 is located below the lower horizontal slide groove 31. The reset mechanism includes a screw rod 34, and the screw rod 34 is rotatably provided in the second mounting groove 33. A push plate 36 is provided on the screw rod 34, and a trigger 37 is provided on the right side of the push plate 36. A motor 35 is provided in the second mounting groove 33, and the motor 35 drives the connecting screw rod 34.

[0033] Initially, the mounting rod 19 is located below the right vertical slot 32. As the fixing member 3 moves, the linkage rod 14 on the mounting plate 13 enters the guide slot 22. The linkage rod 14 acts on the guide slot 22. In addition, the vertical slot 32 limits the mounting rod 19. At this time, the mounting rod 19 rises in the right vertical slot 32, which also causes the support platform 6 to rise. When the linkage rod 14 reaches the left end of the guide slot 22, the mounting rod 19 moves to the upper end of the right vertical slot 32, and reaches the connection between the right vertical slot 32 and the upper transverse slot 31. At the same time, the support platform 6 rises to the highest position, and the cleaning block 7 can resist the lower end of the bearing ring 41. At this time, as the linkage rod 14 continues to move forward, due to the guidance of the transverse slot 31 on the mounting rod 19, the support platform 6 will move with the advancement of the fixing member 3. During the movement, the bearing ring 41 contacts the cleaning strip 5 and rotates, and the cleaning strip 5 cleans the outer periphery of the bearing ring 41 , while the cleaning block 7 cleans the lower end surface of the bearing ring 41 .

[0034] The support platform 6 continues to move forward with the fixing member 3 until the installation rod 19 reaches the connection between the upper horizontal slot 31 and the left vertical slot 32. The portion of the push rod 21 that exceeds the support platform 6 also moves along the inclined surface on the right side of the boss 20 to the point where its thickness is the largest, thus completely pushing the push rod 21 into the guide slot 22. The push rod 21 then acts on the linkage rod 14 to withdraw the linkage rod 14 from the guide slot 22. At this time, the continued movement of the fixing member 3 will not drive the support platform 6 to move. The support platform 6 first descends under the action of gravity, and the installation rod 19 slides down along the left vertical slot 32 to the connection between the left vertical slot 32 and the lower horizontal slot 31. In this process, the mounting rod 19 contacts the spring 17 on the push plate 36, so that the trigger 37 sends a signal to control the motor 35 to start, and the motor 35 drives the screw rod 34 to rotate, and the screw rod 34 drives the push plate 36 to move so that the push plate 36 pushes the mounting rod 19 to the connection between the lower horizontal slide groove 31 and the vertical slide groove 32 on the right, so that the support platform 6 returns to its original position. In the next round of processing, when the mounting rod 19 rises again along the vertical slide groove 32 on the right, it breaks away from the contact with the trigger 37 on the push plate 36, and the trigger 37 sends a signal to the motor 35 again, so that the motor 35 drives the screw rod 34 to reverse, driving the push plate 36 back to its original position.

[0035] Furthermore, the fixing member 3 includes a connecting block 8, the upper end of the connecting block 8 is connected to the conveyor belt 2, the lower part of the connecting block 8 is connected to a supporting block 9, the lower part of the supporting block 9 is rotatably provided with a rotating block 10, the lower part of the rotating block 10 is connected to a plurality of connecting arms 11, and the lower end of the connecting arm 11 is connected to a suction cup 12. The suction cup 12 adsorbs the bearing ring 41 to fix it.

[0036] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
