And the positioning shaft 12 is used for installing the bearing B to be cleaned, and the positioning shaft 12 is arranged in the installation hole in a penetrating mode and is in sealing connection with the installation hole, so that a space for containing liquid can be formed between the inner wall of the container 11 and the positioning shaft 12. The driving mechanism 2 is arranged below the container 11, and an output shaft of the driving mechanism 2 is in transmission connection with the positioning shaft 12 so as to drive the positioning shaft 12 to rotate under the driving of the driving mechanism. And the spraying mechanism 3 is connected to the container 11, and a liquid outlet of the spraying mechanism 3 points to the positioning shaft 12, so that liquid led out from the liquid outlet can be sprayed onto the bearing B to be cleaned.

The working process of the spraying device can be summarized as follows: the bearing B to be cleaned is placed on the positioning shaft 12 so as to accompany the synchronous rotation of the drive mechanism 2. In the process, the spraying mechanism 3 can spray the cleaning liquid with certain pressure on the bearing B, so that the oil stains attached to the bearing B are dissolved and fall to the bottom of the container 11 under the gravity, and the cleaning work of the bearing B is realized.

Through the technical scheme, the oil stain hidden at the dead angle of the bearing B can be effectively removed through the sprayed high-pressure cleaning liquid, and the bearing B can be effectively cleaned in an all-around way along with the high-speed rotation of the driving mechanism 2, so that the cleaning quality can be improved, the single cleaning time of the bearing B is shortened, the cleaning efficiency is effectively improved, and the practicability is better.

In an alternative embodiment, the drive mechanism 2 is configured as an electric motor. Alternatively, the drive mechanism 2 is configured as a combination of a motor and a speed reducer.

In the present disclosure, the positioning shaft 12 is provided with a positioning mechanism 4 for defining the position of the bearing B. The positioning mechanism 4 includes a positioning seat 41, a stop seat 42 and a locking pin 43.

The positioning seat 41 is detachably connected to the positioning shaft 12, and a first step used for abutting against the lower part of the bearing B is arranged on the positioning seat 41; a stopper seat 42 provided with a second step for abutting the upper portion of the bearing B; the locking nail 43 is provided with a stop seat 42, the locking nail 43 is in threaded connection with the positioning shaft 12, so that the stop seat 42 and the positioning seat 41 clamp the bearing B together, the position of the bearing B is fixed, and then the bearing B can synchronously rotate along with the driving mechanism 2, so that the cleaning liquid sprayed out from the spraying mechanism 3 can be comprehensively and thoroughly applied to the bearing B.

In addition, because the positioning seat 41 and the locking nail 43 are detachably connected with the positioning shaft 12, the maintenance and replacement of each part can be facilitated. Meanwhile, due to the fact that the types and specifications of the bearings B are different, the positioning seat 41 and the stop seat 42 with different specifications can be conveniently mounted on the positioning shaft 12, so that different bearings B can be effectively clamped, and the device has high flexibility and applicability.

Referring specifically to fig. 2 and 3, schematic positioning diagrams of two different specifications of bearings are shown. On the basis of the technical concept of the present disclosure, those skilled in the art can adapt the structure of the positioning seat and the stop seat.

The oil leakage disc 16 is provided with a plurality of oil leakage holes which are uniformly distributed, so that the thrown-off cleaning liquid and oil dirt can flow into the bottom of the container 11, and meanwhile, the liquid can be prevented from splashing to the upper part, and a certain isolation effect is achieved.

It should be noted that the height at which the spill plate 16 is located may be set as a warning line. Because oil is lighter than water, oil can float above water. Therefore, when the oil in the container 11 gradually approaches the warning line, the solution at the bottom of the container 11 needs to be discharged, so as to prevent the oil from causing secondary pollution to the bearing, and further ensure the cleaning effect.
