DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4 , the present utility model provides an auxiliary device for embedding a bearing dust cover, which includes a lower pressing handle 1 and an upper pressing handle 2. One ends of the upper pressing handle 2 and the lower pressing handle 1 are provided with a hinge assembly. One ends of the upper pressing handle 2 and the lower pressing handle 1 are movably connected through the hinge assembly. The hinge assembly includes a fixed tube 6 fixedly installed at one end of the upper pressing handle 2. A rotating shaft 7 is rotatably installed in the inner cavity of the fixed tube 6. A positioning ring 8 is fixedly installed at one end of the lower pressing handle 1. Both ends of the rotating shaft 7 are fixedly connected to the inner wall of the corresponding positioning ring 8.

[0020] In this embodiment, through the setting of the hinge assembly, the upper pressing handle 2 and the lower pressing handle 1 can be movably connected together. When the upper pressing handle 2 and the lower pressing handle 1 are separated, the bearing can be placed in the inner cavity of the positioning sleeve 3, or the bearing with the dust cover embedded can be taken out from the inner cavity of the positioning sleeve 3. When pressing the upper pressing handle 2 in the direction of the lower pressing handle 1, the pressing block 4 can be driven to move in the direction of the positioning sleeve 3, and the dust cover can be tightly pressed and embedded on the surface of the bearing through the pressing block 4.

[0021] Preferably, a positioning sleeve 3 for positioning the bearing is fixedly installed on the surface of the lower pressing handle 1. A pressing block 4 is provided at the bottom of the upper pressing handle 2 corresponding to the positioning sleeve 3. A pressing ring 5 adapted to the dust cover is fixedly installed at the bottom of the pressing block 4. One ends of the upper pressing handle 2 and the lower pressing handle 1 where they are hinged are both bent. When the upper pressing handle 2 and the lower pressing handle 1 are in a parallel state, the pressing block 4 is pressed into the inner cavity of the positioning sleeve 3 to embed the dust cover on the surface of the bearing. The top of the pressing block 4 is movably installed at the bottom of the upper pressing handle 2 through a movable connection assembly. The movable connection assembly includes a hinge member 14 fixedly installed at the bottom of the upper pressing handle 2. A connecting member 15 is movably installed at the bottom of the hinge member 14. The bottom of the connecting member 15 is fixedly connected to the top of the pressing block 4.

[0022] Through the coordinated use of the upper pressing handle 2 and the lower pressing handle 1, when it is necessary to embed the dust cover on the surface of the bearing, the user can open the upper pressing handle 2 and the lower pressing handle 1, then place the bearing in the inner cavity of the positioning sleeve 3 and place the dust cover on the top of the bearing. Then the user can press down the upper pressing handle 2. The movement of the upper pressing handle 2 will drive the movement of the pressing block 4, and the dust cover can be tightly pressed and embedded on the surface of the bearing through the pressing ring 5 at the bottom of the pressing block 4, thus completing the assembly work of the dust cover. In this embodiment, the pressing block 4 is movably installed at the bottom of the upper pressing handle 2 through a movable connection assembly.

[0023] Among them, a jacking assembly for facilitating the removal of the bearing with the dust cover assembled from the inner cavity of the positioning sleeve 3 is installed at the bottom of the positioning sleeve 3. The jacking assembly includes a jacking plate 9 slidably installed in the inner cavity of the positioning sleeve 3. A connecting rod 10 is fixedly installed at the bottom of the jacking plate 9. The bottom end of the connecting rod 10 penetrates through the positioning sleeve 3 and extends to the outside of the positioning sleeve 3. An elastic connection assembly is arranged between the bottom end of the connecting rod 10 and the bottom of the positioning sleeve 3. The elastic connection assembly includes a fixing plate 11 fixedly installed at the bottom end of the connecting rod 10. A tension spring 12 is fixedly installed on the top of the fixing plate 11 and outside the connecting rod 10. The top end of the tension spring 12 is fixedly connected to the bottom of the positioning sleeve 3.

[0024] Through the arrangement of the jacking assembly, during the process of pressing and embedding the dust cover on the surface of the bearing, the bearing will move towards the inner cavity of the positioning sleeve 3, thereby pressing the jacking plate 9. The movement of the jacking plate 9 will drive the fixing plate 11 to move through the connecting rod 10, and then the tension spring 12 will be pulled. After the dust cover is embedded on the surface of the bearing, the user can open the upper pressing handle 2. At this time, the pressing block 4 will be separated from the positioning sleeve 3. The reaction force generated by the stretching of the tension spring 12 will drive the jacking plate 9 to move upward through the fixing plate 11 and the connecting rod 10, thereby ejecting the top of the bearing from the positioning sleeve 3, so as to facilitate the user to remove the bearing from the inner cavity of the positioning sleeve 3.

[0025] It is worth noting that a through hole 13 adapted to the connecting rod 10 is opened at the bottom of the positioning sleeve 3. The surface of the connecting rod 10 is slidably connected to the inner wall of the through hole 13. In this embodiment, through the arrangement of the through hole 13, a moving space can be provided for the connecting rod 10, and the surface of the connecting rod 10 will slide in the inner cavity of the through hole 13 when it moves.
