[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown, the skeleton oil seal special installation tool of the utility model comprises a mounting frame 1, a hydraulic cylinder 2, a connecting assembly 3 and a skeleton pressing plate 4, the hydraulic cylinder 2 is arranged on the mounting frame 1, and the skeleton pressing plate 4 is adjustably arranged on the hydraulic cylinder 2 through the connecting assembly 3, wherein:

[0025] The mounting frame 1 comprises an upper pad 11, a bottom plate 13, an adjusting screw 14 and an adjusting nut 15. The adjusting screw 14 is symmetrically arranged at both ends of the bottom plate 13, and the upper pad 11 is adjustably arranged on the adjusting screw 14 through the adjusting nut;

[0026] The skeleton pressing plate 4 includes an upper pressing head 41 , a die base 42 and screws 44 , and the die base 42 is connected to the upper pressing head 41 via the screws 44 .

[0027] Furthermore, in the special installation tool for skeleton oil seal of the utility model, a mounting hole 12 is provided in the middle of the upper pad 11. After the output end of the hydraulic cylinder 2 passes through the mounting hole 12, it is fixed to the upper pad 11 by bolts, thereby effectively ensuring the installation of the hydraulic cylinder 2 and providing downward pressure through the hydraulic cylinder 2.

[0028] Furthermore, in the special installation tool for skeleton oil seal of the utility model, the connecting component 3 includes an upper hinge ear 31, a lower hinge ear 32 and a hinge shaft 33. The upper hinge ear 31 is welded to the output end of the hydraulic cylinder 2, and the lower hinge ear 32 is welded to the upper pressure head 41. The upper hinge ear 31 and the lower hinge ear 32 are connected by the hinge shaft 33, thereby ensuring fine-tuning between the upper pressure head 41 and the hydraulic cylinder 2 through the connecting component 3.

[0029] Furthermore, in the special installation tool for skeleton oil seal of the utility model, the adjusting screw 14 is threadedly engaged with the upper pad 11, and the adjusting nut 15 is distributed on the upper and lower sides of the upper pad 11. The adjusting nut 15 is threadedly engaged with the adjusting screw 14, thereby ensuring that the upper pad 11 can be adjusted in height, thereby being suitable for the installation of skeleton oil seals of more specifications.

[0030] Furthermore, in the skeleton oil seal special installation tool of the present invention, an annular boss 43 is provided at the bottom of the die base 42, and the diameter of the annular boss 43 matches the diameter of the skeleton oil seal, thereby ensuring that the skeleton oil seal is evenly stressed during installation and avoiding damage.

[0031] When assembling the skeleton oil seal, first, insert the skeleton oil seal into the die seat 42, and put the bearing gland into the center of the bottom plate 13, check to confirm that there are no burrs, sand, iron filings and other debris, and evenly apply lithium-based grease at the entrance of the bearing gland to reduce the friction resistance during the oil seal installation process. Select a die seat 42 that matches the skeleton oil seal, and install it on the upper pressure head 41 through screws 44. At this time, start the hydraulic cylinder 2 so that the output end drives the upper pressure head 41 to move downward through the connecting component 3. When the annular boss 43 at the bottom of the die seat 42 drives the skeleton oil seal into the gland, the lower hinge ear 32 is fine-tuned through the hinge shaft 33 to ensure that the annular boss 43 applies uniform pressure to the skeleton oil seal. Pay attention to observe that the oil seal cannot be tilted with the inner hole during pressing, and the oil seal is pressed into the bottom of the bearing gland at a uniform speed. When the bearing gland is too high, the adjusting nut 15 on the adjusting screw 14 can be turned to adjust the upper pad 11 upward, thereby increasing the distance between the upper pad 11 and the bottom plate 13, so that it is suitable for the installation of skeleton oil seals on bearing glands of various specifications.
