DETAILED DESCRIPTION

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] like Figure 1 , 2 As shown, a bearing ring cleaning device includes a workbench 1, and a plurality of sleeves 2 are provided in the circumferential direction of the workbench 1 surface. A turntable 6 is provided in each sleeve 2 of the workbench 1, and an annular space for spraying is reserved between the turntable 6 and the sleeve 2. Two external spray pipes 4 are symmetrically provided in the annular space. The external spray pipes 4 are vertically arranged, and the top of the external spray pipes 4 is closed. A plurality of spray holes are provided in the vertical direction on one side of the pipe wall facing the center of the turntable 6. The two external spray pipes 4 in each sleeve are connected to a transverse pipe 13 at the same time. The transverse pipe 13 is connected to a cleaning liquid storage tank after passing through the sleeve 2.

[0027] A bearing ring fixing structure is provided on the top surface of the turntable 6, and an inner spray pipe 3 is provided through the center of the turntable 6. The inner spray pipe 3 is vertically arranged, fixed relative to the workbench 1, and rotates relative to the turntable 6. The top of the inner spray pipe 3 is also closed, and a plurality of spray holes are provided in the vertical direction of the pipe wall. The inner spray pipe 3 is connected to the cleaning liquid storage tank, and the sleeve 2 is symmetrically provided with two cleaning mechanisms 5 for cleaning the outer wall of the bearing ring.

[0028] In the utility model, the rotation power source of the turntable 6 is a motor. There are various driving modes, and they are all prior art. Now, an example is used to illustrate. The turntable 6 is equipped with a gear shaft 12, which is rotatably connected to the workbench 1. The gear shaft 12 is a hollow shaft, and the inner spray pipe 3 passes through the center of the gear shaft 12. A rotating shaft 9 is provided at the center of the workbench 1. The rotating shaft 9 is provided with a transmission gear 8 meshing with the gear on the gear shaft 12. A driving motor is also provided below the workbench 1. A gear rotating structure 10 is provided between the driving motor and the rotating shaft 9. The motor power is transmitted to the rotating shaft 9 through the gear rotating structure 10, and then transmitted to the gear shaft 12 through the transmission gear 8, thereby driving the turntable 6 to rotate. The turntable 6 rotates, driving the bearing ring 7 on the turntable 6 to rotate, the inner spray pipe 3 washes the inner side of the bearing ring 7, the two outer spray pipes 4 wash the outer side of the bearing ring 7, and the two cleaning mechanisms 5 further wipe the outer side of the bearing ring 7 to achieve the cleaning of the bearing ring 7.

[0029] The structure of the cleaning mechanism 5 is as follows: Figure 3 As shown, it includes a fixing plate 57, a cleaning cotton layer 54, a screw 52 and a guide rod 55. The guide rod 5 and the screw 52 are parallel and both mounted on the fixing plate 57. The cleaning cotton layer 54 is arranged on the side of the fixing plate 57 away from the screw 52. The side of the cleaning cotton layer 54 away from the fixing plate 57 is a concave curved surface corresponding to the outer side of the bearing ring. The sleeve 2 is provided with a through hole corresponding to the screw 52 and a guide hole corresponding to the guide rod 55. The screw 52 movably passes through the through hole, the guide rod 55 movably passes through the guide hole, and forms a guiding and limiting structure with the guide hole to ensure that there is a gap between the screw 52 and the wall of the through hole. The outer end of the screw 52, ​​that is, the end away from the fixing plate 57, extends out of the sleeve 2, and a nut is corresponding to this part. The part of the screw 52 extending into the sleeve 2 is sleeved with a spring 53.

[0030] In this structure, the nut 51 limits the length of the screw 52 extending into the sleeve 2. After the bearing ring 7 is placed, the length of the screws 52 of the two cleaning mechanisms 5 extending into the sleeve is adjusted so that the cleaning cotton layer 54 is close to the outer side of the bearing ring 7. When the bearing ring 7 rotates, the cleaning cotton layer 54 wipes the outer side of the bearing ring 7. Two cleaning mechanisms 5 are symmetrically arranged in each sleeve 2. Even if the center of the bearing ring 7 and the turntable 6 are not concentric, and the bearing ring 7 is placed eccentrically, this structure can ensure that one of the cleaning mechanisms 5 can clean the bearing ring 7.

[0031] Bearing ring fixing structure Figure 4 , Figure 5As shown, it includes three magnets 61 arranged around the center of the turntable 6, and the top surfaces of the three magnets 61 are flush and protrude from the upper surface of the turntable 6. In order to ensure that the bearing ring and the turntable 6 are concentric after placement, three copper positioning pins 62 are arranged around the center of the upper surface of the turntable 6. The top of the copper positioning pins 62 is arranged higher than the top surface of the magnet 61, and the radius of the circle corresponding to the outermost end of the circumferential surface of the three copper positioning pins 62 corresponds to the inner diameter of the bearing ring. The three copper positioning pins 62 guide the placement of the bearing ring 7, and the bearing ring 7 is lowered along the three copper positioning pins 62. Since the three copper positioning pins 62 are arranged around the center of the turntable 6, the bearing ring 7 is guided by them until the bearing ring 7 abuts against the magnet 61, and the bearing ring 7 is fixed by the magnet 61, so that the bearing ring 7 is fixed, and the concentricity of the bearing ring 7 and the turntable 6 is ensured.

[0032] In the utility model, a guide hole is provided at the center of the workbench 1, a guide pipe 11 is provided in the guide hole, the rotating shaft 9 is a hollow shaft, the guide pipe 11 passes through the rotating shaft 9, a guide ring groove 102 is provided on the workbench surface corresponding to the annular space position, and a guide straight groove 101 is provided on the top surface of the workbench 1 for connecting the guide ring groove 102 and the guide hole. The cleaning liquid used by the sleeve 2 to clean the bearing ring 7 enters the guide straight groove 101 through the guide ring groove 102, and finally flows out through the guide pipe 11 and is collected.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
