Description

Technical Field

[0001] This utility model belongs to the field of bearing manufacturing, and in particular relates to a bearing ring cleaning device. Background Technology

[0002] Bearing races consist of an inner ring and an outer ring. Before assembling the bearing, the inner and outer surfaces of the bearing races must be cleaned to remove any impurities, thereby ensuring that the rolling elements of the raceway are not damaged after assembly.

[0003] Currently, bearing ring cleaning devices include ring fixing fixtures and flexible brushes or sponges. The ring fixing fixtures mostly use a three-jaw chuck structure, which clamps the inner or outer surface of the bearing ring with the jaws to fix it, so that the ring rotates with the chuck. During the rotation, the flexible brush or sponge is used to wipe and clean the inner and outer surfaces of the bearing ring.

[0004] However, during the cleaning process, it was found that because the clamps hold the bearing race tightly on the inner or outer surface, they occupy the surface area of ​​the bearing race, preventing the bearing race surface from being completely exposed for cleaning. This results in some areas being missed when cleaning with the flexible brush or sponge, meaning the cleaning is not thorough. The missed areas must be manually wiped clean afterwards, affecting the efficiency and effectiveness of the bearing race cleaning. Utility Model Content

[0005] In view of this, the present invention aims to provide a bearing ring cleaning device to achieve thorough cleaning of the inner and outer surfaces of the bearing rings, thereby improving the efficiency and effectiveness of bearing ring surface cleaning.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] like Figure 1 , Figure 2 As shown, a bearing ring cleaning device includes a barrel 1 with an open top, a cleaning mechanism disposed above the barrel 1, and a fixed disk 5 and a movable disk 2 disposed inside the barrel 1. The cleaning mechanism includes a push element 14 fixed relative to the barrel 1, a motor 11 disposed at the pushing end of the push element 14 via a connecting plate 13, and a rotating arm 10 driven by the motor 11. The push element 14 is preferably a pneumatic cylinder or a hydraulic cylinder. The rotation center of the rotating arm 10 is the central axis of the fixed disk. A U-shaped block 9 with an opening facing downward is disposed at the distal end of the rotating arm 10. Two flexible cleaning elements 8 are disposed opposite each other inside the U-shaped block 9. The flexible cleaning elements 8 are preferably sponges.

[0031] The fixing plate 5 is installed inside the bucket 1, and there is a distance between the fixing plate 5 and the bottom of the bucket 1. The structure of the fixing plate is as follows. Figure 3 As shown, a through hole 52 is formed at its center, and a positioning ring groove 51 for placing the bearing ring is formed around the center on the top surface. The width of the positioning ring groove 51 corresponds to the thickness of the bearing ring to position the placed bearing ring. Figure 4 As shown, the bearing race 17 is placed in the positioning ring groove 51, which positions it to ensure concentricity with the fixed plate 5. The fixed plate 5 has several radial clearance grooves 54, preferably four grooves 54 evenly arranged circumferentially. The clearance grooves 54 extend radially out of the positioning ring groove and vertically through the upper and lower bottom surfaces of the fixed plate 5. After the fixed plate 5 is inserted into the bucket 1, two flexible cleaning elements 8 are distributed on both sides of the positioning ring groove 51. The distance between the two flexible cleaning elements 8 is less than the thickness of the bearing race, ensuring that the two flexible cleaning elements 8 can closely adhere to the inner and outer surfaces of the bearing race for cleaning.

[0032] The movable disk 2 is located below the fixed disk 5 and directly opposite the through hole 52. The diameter of the movable disk 2 is smaller than the diameter of the through hole 52, preferably 10-15 mm smaller. A lifting element 16 is provided at the bottom of the bucket 1. The lifting element 16 is preferably a cylinder or hydraulic cylinder. The movable disk 2 is installed at the lifting end of the lifting element 16, which can drive the movable disk 2 to move upwards. Four connecting arms 3 are radially arranged around the periphery of the movable disk 2. Each of the four connecting arms 3 corresponds to a clearance groove 54. A magnet 4 is fixed to the far end of the top surface of each connecting arm 3. The magnet 4 is located directly below the positioning ring groove 51, and the width of the magnet 4 is smaller than the width of the positioning ring groove 51.

[0033] To improve the cleaning effect of the extraction ring, a spraying mechanism is installed inside the tank 1. The spraying mechanism includes an annular outer spray pipe 6 and an annular inner spray pipe 7. The outer spray pipe 6 is located on the inner wall of the tank 1 near the top and is connected to a high-pressure water source. Several spray holes are opened on the outer spray pipe 6 facing the positioning ring groove 51. The inner spray pipe 7 is fixed to the top surface of the movable plate 2 by a vertical rod 71. A pipe connector 72 is connected downward to the inner spray pipe 7. The pipe connector 72 is connected to a high-pressure water source through a hose. Several spray holes are opened on the inner spray pipe 7 facing the positioning ring groove 51.

[0034] The working state of this utility model is as follows: Figure 4 , Figure 5 As shown, the bearing ring 17 is first placed in the positioning ring groove 51, with the inner spray pipe 7 inside and the outer spray pipe 6 outside. The lifting element 16 is activated, causing the moving disk 2 and connecting arm 3 to move upwards. When the connecting arm 3 moves from the corresponding clearance groove 54 to the bottom surface of the bearing ring 17 in the positioning ring groove 51, the magnet 4 attracts the bearing ring 17 and fixes it to the connecting arm 3. The bearing ring 17 then moves upwards with the connecting arm 3 until it detaches from the positioning ring groove 51 and moves above the fixed disk 5. At this point, the inner and outer surfaces of the bearing ring 17 are fully exposed, and both the outer spray pipe 6 and the inner spray pipe 7 are connected to a high-pressure water source to spray and clean the inner and outer surfaces of the bearing ring 17. After spraying, the cleaning mechanism moves downwards, allowing the two flexible cleaning parts 8 to adhere tightly to the inner and outer surfaces of the bearing ring 17. The motor 11 is activated to drive the rotating arm 10 to rotate, causing the flexible cleaning parts 8 to wipe and clean the inner and outer surfaces of the bearing ring 17.

[0035] In this invention, several guide channels 53 are formed in the inner wall of the positioning ring groove 51. The guide channels 53 penetrate the wall of the through hole 52, and the bottom of the guide channels 53 is inclined. The spray water in the positioning ring groove 51 flows to the bottom of the bucket 1 through the guide channels 53, preventing water accumulation in the positioning ring groove. A drain outlet is formed on the side wall of the bucket 1 near the bottom of the bucket (shown in the attached figure) to facilitate the final discharge of the spray water.

[0036] In this utility model, a telescopic protective cover 15 is provided between the bottom surface of the movable disk 2 and the lifting element 16. The telescopic protective cover 15 extends and retracts synchronously with the push rod of the lifting element 16.

[0037] This invention enables thorough cleaning of both the inner and outer surfaces of the bearing race 17, improving the efficiency and effectiveness of bearing race surface cleaning.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
