DETAILED DESCRIPTION

[0022] Example 1

[0023] As Figs. 1-7 shown, a mechanical bearing oiling structure includes a support box 1, a workbench 2 is installed in the middle of the support box 1, a rotating support disc 3 is rotatably connected in the middle of the workbench 2, four fixed assemblies are arranged in an annular array on the rotating support disc 3, a driving assembly is arranged at the bottom of the rotating support disc 3, an oil injection assembly is arranged on the inner wall of one side of the support box 1, and a work window is formed on one side of the support box 1. Through the driving assembly, the oil injection assembly and the fixed assembly, the operator does not need to wait for one bearing to complete oiling before operating the next bearing, and seamless connection is achieved through multiple stations and the rotating support disc 3, the waiting time is reduced, and the bearing oiling efficiency is improved.

[0024] The fixed assembly includes four protective shells 4, the four protective shells 4 are arranged in an annular array on the same rotating support disc 3, a first electric telescopic rod 5 is installed in the protective shell 4, a support plate 6 is installed at the top of the first electric telescopic rod 5, a rotating shaft 8 is installed at the top end center of the support plate 6, two guide columns 7 are symmetrically installed at the bottom of the support plate 6, the fixed assembly further includes four fixed columns 9, the fixed columns 9 are rotatably connected to the top of the rotating shaft 8, four sliding groove plates 10 are arranged in an annular array in the fixed column 9, a spring telescopic rod 11 is installed in the sliding groove plate 10, a support block 12 is connected to the spring telescopic rod 11, an inclined surface is arranged on the support block 12, and the side of the support block 12 with the inclined surface faces the center of the fixed column 9;

[0025] During operation, the bearing is placed on the fixed column 9. The bearing's inclined surface on the support block 12 and the bearing's force facilitate the movement of the support block 12, allowing the four support blocks 12 to support the inner ring of the bearing. This makes it easy for the operator to position and install the bearing. The U-shaped sliding groove plate 10 can limit the movement of the support block 12. As the bearing pushes the support block 12, it retracts and moves towards the center of the fixed column 9, stretching the spring telescopic rod 11. The spring telescopic rod 11 generates an elastic clamping force, thus tightening the support block 12 within the inner ring of the bearing and fixing the bearing in place. This prevents the bearing from detaching during oil injection. After the bearing is installed, the drive assembly drives the rotating support disk 3 to rotate, so that the fixed part on the next fixed assembly is positioned in the working window. The bearing is then fixed on the fixed assembly again. The drive assembly rotates the rotating support disk 3 again, so that the first fixed bearing is positioned below the oil injection assembly. At the same time, the third fixed assembly rotates to the working window to place the bearing. This process is repeated, with bearings placed on the four fixed assemblies in sequence. Driven by the drive assembly, continuous operation is performed, improving oil injection efficiency.

[0026] Example 2

[0027] like Figs. 3-7 As shown, the oil injection assembly includes a support frame 13, which is installed on one side of the inner wall of the support housing 1. A first servo motor 14 is mounted on the support frame 13, and a drive shaft 15 is connected to the output shaft of the first servo motor 14. A fixing collar 16 is installed at the bottom of the drive shaft 15, and the diameter of the fixing collar 16 is equal to that of the inner ring of the bearing. The oil injection assembly also includes two second electric telescopic rods 17, the tops of which are mounted on the bottom of the same support frame 13, and the bottoms of which are mounted on the same oil injection collar 18. The oil injection collar 18 is slidably connected to the fixing... On the collar 16, an oil injection pipe 19 is installed on the oil injection collar 18. The end of the oil injection pipe 19 away from the oil injection collar 18 is equipped with a pipe interface 20. In use, the external lubricating oil feeding equipment is connected to the pipe interface 20 through its external pipe, thereby supplying lubricating oil to the oil injection pipe 19 to facilitate oiling the bearing. Two rubber scrapers 22 and two brushes 21 are symmetrically installed on the top of the inner wall of the oil injection collar 18. If it is viscous lubricating oil to be applied to the bearing, the rubber scrapers 22 will smooth the lubricating oil on the bearing, so that the brushes 21 can evenly apply it to the bearing.

[0028] When working, the first fixed assembly fixes the bearing below the oil injection assembly. The first electric telescopic rod 5 on the fixed assembly drives the support plate 6 to rise, so that the support plate 6 drives the fixed column 9 connected thereto and the bearing placed thereon to move upward, so that the bearing on the fixed column 9 rises to contact the bottom of the fixed sleeve ring 16, so that the fixed sleeve ring 16 is extruded with the first electric telescopic rod 5 to fix the inner ring of the bearing, and at the same time, the oil injection sleeve ring 18 is completely sleeved on the outer ring of the bearing. The first servo motor 14 drives the driving shaft 15 to rotate, and then the driving shaft 15 drives the fixed sleeve ring 16 connected at the bottom thereof to rotate, and the fixed sleeve ring 16 drives the bearing extruded at the bottom to rotate, and then the inner ring of the bearing drives the fixed shaft on the rotating shaft 8 on the support plate 6 through the support block 12 fixed thereto. When the bearing rotates, the oil injection pipe 19 injects lubricating oil into the oil injection sleeve ring 18, so that the lubricating oil falls on the bearing rollers between the inner and outer rings of the bearing, and then the brush 21 uniformly applies the lubricating oil on the bearing rollers. As the bearing rotates, the lubricating oil is applied on the bearing rollers, and the oiling of the bearing is completed. The first electric telescopic rod 5 drives the support plate 6 to reset. The close fit between the oil injection sleeve ring 18 and the outer ring of the bearing ensures that the lubricating oil can be accurately injected into the bearing, reducing the leakage or splashing of the lubricating oil.

[0029] Through the cooperation of the oil injection assembly, the rotating support disc 3 and the fixed assembly, the oil injection process can be continuously carried out without waiting, further improving the overall work efficiency. The bearing rotates under the drive of the fixed sleeve ring 16, and under the action of centrifugal force, the lubricating oil is uniformly injected onto the rollers between the inner and outer rings of the bearing through the oil injection pipe 19, ensuring that the lubricating oil can be uniformly distributed, avoiding local insufficient or excessive lubrication. The design of the brush 21 and the rubber scraper 22 can uniformly apply the lubricating oil on the bearing rollers, ensuring that the lubrication effect is more uniform and complete.

[0030] Example 3

[0031] As Figs. 1-2As shown, the driving assembly comprises a rotating main shaft 27 and a mounting box 25, the top of the rotating main shaft 27 is connected with the rotating support disc 3, and the bottom is rotatably connected at the top of the mounting box 25, one side of the mounting box 25 is rotatably connected with a connecting shaft 24, the connecting shaft 24 and the rotating main shaft 27 are both provided with a bevel gear 26 at the end of the mounting box 25, and the two bevel gears 26 are meshed with each other, the end of the connecting shaft 24 away from the mounting box 25 is connected with a second servo motor 23, and the second servo motor 23 is mounted on the support box body 1; during work, the second servo motor 23 drives the connecting shaft 24 connected therewith to rotate on the mounting box 25, the connecting shaft 24 drives the other bevel gear 26 meshed therewith to rotate through the bevel gear 26 thereon, and then drives the driving main shaft to rotate, the driving main shaft drives the rotating support plate 6 to rotate, and then the rotating support plate 6 drives the fixed assembly thereon to rotate, so that the bearings are conveniently fixed, oiled and removed one by one.
