[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0033] A deep groove ball bearing cage cleaning device, the structure of which can be Figure 1-Figure 5As shown in the figure, in this embodiment, the deep groove ball bearing retainer cleaning device includes: a base 1, a carrier plate 3 and a flushing assembly. A liquid storage cavity 11 for storing cleaning liquid is provided inside the base 1, and a treatment cylinder 2 is provided on the top surface of the base 1, and the bottom end of the treatment cylinder 2 is connected to the liquid storage cavity 11. The carrier plate 3 is rotatably arranged inside the treatment cylinder 2, and the retainer 9 entering the treatment cylinder 2 can be supported and fixed by the carrier plate 3, and the retainer 9 can be driven to rotate during the cleaning process, thereby improving the cleaning efficiency. The flushing assembly includes: a cover 4, a flushing pipe 5 and a circulation pump 6, wherein the cover 4 is detachably arranged on the top of the treatment cylinder 2, the flushing pipe 5 is arranged on the cover 4, and the bottom end of the flushing pipe 5 is inserted into the treatment cylinder 2, a diversion cavity 51 is provided in the inner wall of the flushing pipe 5, and a plurality of diversion holes 52 connected to the diversion cavity 51 are also provided on the outer wall of the flushing pipe 5. During installation, the liquid inlet of the circulation pump 6 should be connected to the liquid storage cavity 11, and the liquid outlet of the circulation pump 6 should be connected to the diversion cavity 51 through the hose 61. During cleaning, the circulation pump 6 can pump the cleaning liquid stored in the liquid storage cavity 11 into the diversion cavity 51, and spray it to the retaining frame 9 in the treatment cylinder 2 through the diversion hole 52, so as to remove the pollutants attached to the retaining frame 9. Accordingly, the staff can also drive the carrier plate 3 to rotate during the flushing and cleaning process, so that each position of the retaining frame 9 can be well flushed, thereby improving the efficiency and effect of the cleaning work.

[0034] In addition, in order to facilitate the recycling of the cleaning liquid, a plurality of drainage cutouts 31 should be provided on the carrier plate 3. When the cleaning liquid is separated from the retaining frame 9, the cleaning liquid will flow into the liquid storage cavity 11 along the drainage cutouts 31 so that the circulating pump 6 can extract it for use again.

[0035] Optionally, in order to prevent the solid contaminants inside the liquid storage cavity 11 from affecting the normal operation of the circulation pump 6, a filter plate 12 may be provided inside the liquid storage cavity 11, and the filter plate 12 should be located between the carrier plate 3 and the liquid inlet end of the circulation pump 6. When the cleaning liquid is circulated inside the device, the filter plate 12 can intercept and filter the solid contaminants, thereby preventing the circulation pump 6 from malfunctioning due to the entry of solid contaminants.

[0036] It should be noted that the cleaning liquid in this embodiment can be a common bearing-specific cleaning agent (such as a water-based weak alkaline cleaning liquid), and the staff can also configure a special cleaning liquid according to the pollutant components on the retaining frame 9, thereby further improving the cleaning effect of the retaining frame 9.

[0037] Since the retainer 9 is provided with a plurality of slots for accommodating the rolling elements, it is easy to produce a cleaning dead angle on the retainer 9 during the cleaning process. Figure 4As shown, in this embodiment, a plurality of annularly arranged counterflow grooves 21 are provided on the inner side wall of the treatment barrel 2. When the cleaning liquid sprayed from the flushing pipe 5 contacts the counterflow grooves 21, the counterflow grooves 21 can cause the cleaning liquid to form turbulent flow inside the treatment barrel 2. Compared with the common flat flow state, the cleaning liquid in the turbulent flow state has a stronger ability to remove pollutants, so the cleaning effect of the retainer 9 can be improved.

[0038] In addition, in order to further improve the turbulence of the cleaning liquid inside the treatment tube 2, a plurality of anti-flow strips 22 may be provided on the inner side wall of the treatment tube 2, and the plurality of anti-flow strips 22 should be arranged alternately with the plurality of anti-flow grooves 21. Since the anti-flow strips 22 and the anti-flow grooves 21 can guide the flow of the cleaning liquid in different directions, after the anti-flow strips 22 are provided, the cleaning liquid inside the treatment tube 2 will flow in a more chaotic form, thereby further improving the cleaning effect of the retainer 9.

[0039] In order to prevent the holder 9 inside the treatment cylinder 2 from moving abnormally during the flushing process, in this embodiment, a plurality of positioning members for fixing the holder 9 are further provided on the carrier plate 3, and the plurality of positioning members are arranged in a ring shape around the center of the carrier plate 3. Figure 3 As shown, the positioning member may include a positioning block 81 and a positioning rod 82, and the positioning rod 82 is arranged on the top surface of the positioning block 81. The carrier plate 3 is provided with a guide groove 33 arranged along the radial direction of the carrier plate 3, a bearing rod 34 is arranged inside the guide groove 33, and the positioning block 81 is slidably arranged on the bearing rod 34. When the holder 9 to be processed enters the inside of the processing cylinder 2, the staff can drive each positioning member to slide, so as to limit the inner side wall of the holder 9 with the help of the positioning rod 82 of each positioning member, and then fix the relative position of the holder 9 and the carrier plate 3, and ensure that the holder 9 rotates synchronously with the carrier plate 3. Correspondingly, when the diameter specification of the holder 9 to be processed changes, the staff can also flexibly adjust the position of each positioning member, so that the device can clean the holders 9 of different specifications.

[0040] Optionally, in order to ensure that the retaining frame 9 obtains a good tensioning and fixing effect, a spring 83 may be sleeved on the bearing rod 34, and one end of the spring 83 should be connected to the positioning block 81, and the other end should be connected to the inner wall of the guide groove 33. When the retaining frame 9 is fixed by the positioning member, the spring 83 will be compressed, and the elastic force generated by the compression of the spring 83 can make the positioning rod 82 of the positioning member press against the inner wall of the retaining frame 9, thereby improving the positioning effect of the retaining frame 9.

[0041] In addition, in order to facilitate the staff to drive the carrier plate 3 to rotate, the device may also include an operating rod 7. Specifically, the operating rod 7 is rotatably arranged in the flushing pipe 5, a connecting block 71 is arranged at the bottom end of the operating rod 7, and a connecting groove 32 for accommodating the connecting block 71 is arranged on the top surface of the carrier plate 3. When the cover 4 is installed on the top of the treatment cylinder 2, the connecting block 71 at the bottom of the operating rod 7 will be inserted into the connecting groove 32. Figure 5 As shown, the connecting block 71 in this embodiment can be set as a square protrusion, and the connecting groove 32 should be set as a square groove. When the operating rod 71 with the square protrusion is inserted into the connecting groove 32 of the square groove, the staff can rotate the operating rod 71 to make the supporting plate 3 rotate synchronously, thereby facilitating improving the cleaning efficiency of the retaining frame 9.

[0042] As an optional implementation of this embodiment, in order to prevent the cleaning liquid inside the device from overflowing, a sealing groove for accommodating the top of the processing tube 2 can be provided on the bottom surface of the cover 4, and a sealing gasket 41 is provided inside the sealing groove. When the cover 4 is installed on the top of the processing tube 2, the sealing gasket 41 can block the joint gap between the processing tube 2 and the cover 4, thereby improving the sealing effect of the joint gap and preventing the cleaning liquid from flowing out along the joint gap.

[0043] The effects of the above scheme are described below:

[0044] This embodiment provides a deep groove ball bearing cage cleaning device, which can fix the cage by a positioning member, and can rotate the cage by rotating the carrier plate, thereby improving the cleaning efficiency of the cage. Secondly, the device can form turbulent flow inside the treatment cylinder through the backflow strip and the backflow groove, thereby improving the cleaning effect of the cage. In addition, the device can also adjust the position of the positioning member according to actual needs, so as to adapt to cages of different diameter specifications.

[0045] 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.
