Description

Technical Field

[0001] The invention relates to the technical field of bearing production, in particular to a device for automatically coating a sealing agent on the surface of an outer ring of an insulating bearing. Background Art

[0002] Sealing agents can effectively prevent external impurities such as dust, moisture, and metal particles from entering the bearing, thereby ensuring the normal operation of the bearing and extending its service life. In addition, sealing agents can also prevent the leakage of lubricants, maintain the lubrication effect of the bearing, and further improve the working efficiency and stability of the bearing.

[0003] Currently, in bearing manufacturing, to maintain bearing stability and extend its service life during use, a sealant coating is required on the outer ring surface of the bearing. Conventional technology typically involves manually applying the sealant along the outer ring using a ruler. During the coating process, it is crucial to ensure uniformity and avoid bubbles or uncovered areas. However, manual application is difficult to achieve uniformity and is inefficient.

The second belt 54 is transmission-connected to a second driven wheel 55 fixedly connected to the threaded column 48, and the axis of the second driven wheel 55 is fixedly connected to a rotating column 56 rotatably connected to the sliding plate 44. The rotating column 56 is arranged to contact the protective cover 24, and a second tension spring 50 is installed between the second driven wheel 55 and the threaded block 47. The two ends of the second tension spring 50 are respectively rotationally connected to the second driven wheel 55 and the threaded block 47.

[0039] Working principle: When coating the bearing, the bearing sleeve is set on the outer side of the three groups of support columns 59, and the bearing is pushed to contact the limit plate 60. At this time, the bearing is positioned by the action of the three groups of electric telescopic rods 58, and then the sealing agent is transported to the inside of the docking tube 31. The sealing agent enters the inside of the outer tube 32 through the docking tube 31, and the second sealing tube 28 is moved by the extrusion of the sealing agent, thereby driving the sliding tube 27 to move. The movement of the sliding tube 27 causes the diverter tube 26 to drive the two groups of bent tubes 25 to move, thereby driving the distribution tube 10 to move. The movement of the distribution tube 10 causes the connecting tube 11 to drive the fixed sleeve 12 and The fixed tube 13 moves downward, and the feed tube 17 drives the connecting cover 7 and the coating sponge 8 to move downward, so that the coating sponge 8 first contacts and fits the surface of the bearing outer ring, and as the sealing agent continues to be squeezed in, the second sealing tube 28 drives the diversion tube 26, two sets of curved tubes 25, the feed tube 10, the connecting tube 11, the fixed sleeve 12 and the fixed tube 13 to continue to move downward. Since the coating sponge 8 that contacts and squeezes the bearing outer ring will not continue to move, when the second sealing tube 28 moves downward into the thickened tube 33, the fixed sleeve 12 and the fixed tube 13 also undergo relative displacement with the first sealing tube 14, so that the first sealing tube 14 enters the fixed sleeve 12.

[0040] Among them, after the second sealing tube 28 enters the thickened tube 33, the second sealing tube 28 is connected to the inner cavity of the thickened tube 33 through the second through hole 29, so that the sealing agent circulating in the docking tube 31, the outer tube 32 and the thickened tube 33 enters the interior of the sliding tube 27 through the second through hole 29, and is then transported to the diversion tube 26 through the sliding tube 27, and then transported to the distribution tube 10 through the bent tube 25, and then through the action of the distribution tube 10, the sealing agent enters the fixed sleeve 12 through multiple groups of connecting tubes 11.

[0041] Furthermore, after the first sealing tube 14 enters the interior of the fixed sleeve 12, the first sealing tube 14 is connected to the inner cavity of the fixed sleeve 12 through the first through hole 15, so that the sealing agent circulating in the fixed sleeve 12 enters the interior of the delivery pipe 17 through the first through hole 15, and then the sealing agent is transported to the coating sponge 8 through the action of the delivery pipe 17 and the connecting cover 7, and the bearing is coated through the coating sponge 8.

[0042] It is worth noting that, due to the different widths of the bearings, multiple groups of coating sponges 8 are provided in this solution. Only the coating sponges 8 that are in compression contact with the bearings will cause relative sliding between the fixed sleeve 12, the fixed tube 13, and the first sealing tube 14, thereby transporting the sealing agent into the coating sponges 8. The coating sponges 8 that are not in contact with the bearings do not have compression contact with the bearings, so the sealing agent will not be transported to the coating sponges 8 that are not in contact with the bearings. With this design, bearings of different specifications can be coated without having to replace the coating head, and there will be no dripping of the sealing agent, which would cause waste.

[0043] In the process of sliding tube 27 moving downward, protective cover 24 will also be driven downward, so that connecting column 35 drives sliding column 36 to move downward, and then sleeve 37 drives connecting frame 19 to move downward, and through the downward movement of connecting frame 19, rotating shaft 20 drives rotating roller 21 to move downward, and in the process of rotating roller 21 moving downward, it will contact with bearing, and through the action of sliding column 36, sleeve 37 and second spring 38, rotating roller 21 can contact with bearings of different specifications, after rotating roller 21 contacts with bearing, motor 40 is started, and the action of motor 40 makes first driving wheel 41 rotate, thereby makes first belt 42 rotate, and then makes two groups of first driven wheels 43 connected thereto rotate, and then makes two groups of rotating shafts 20 drive rotating roller 21 to rotate, and the bearing is rotated by the rotation of rotating roller 21, and then the outer ring of bearing is coated;

[0044] When the motor 40 is started and drives the first driving wheel 41 to rotate, the first driving wheel 41 will drive the transmission shaft 52 to rotate, thereby driving the second driving wheel 53 to rotate, and then driving the second driven wheel 55 to rotate through the second belt 54, thereby driving the threaded column 48 to rotate, and then the threaded block 47 drives the extrusion sleeve 46 to move, so that the extrusion sleeve 46 is squeezed onto the support platform 1, and the protective cover 24 can be squeezed by the reaction force to ensure the stability of the protective cover 24, so that the coating sponge 8 and the rotating roller 21 can always maintain the coating working state. It is worth noting that the motor 40 is always in the started state during the coating work, that is, the threaded column 48 is always rotating, so after the extrusion sleeve 46 is squeezed and contacted with the support platform 1, the threaded block 47 will be separated from the threaded column 48 on the outer side of the connecting shaft 49, and the second tension spring 50 is used to make the threaded block 47 always closely fit the threaded column 48, so when the threaded column 48 is always rotating, the threaded block 47 will not continue to move, but when the threaded column 48 is reversed, the threaded block 47 can move back and reset by the action of the second tension spring 50;

[0045] After the coating work is completed, the sealing agent is stopped from being supplied, and the sliding tube 27 and the coating sponge 8 are all reset to the initial state through the action of the first tension spring 34 and the first spring 16, thereby facilitating the coating work of the next group of bearings.
