Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical technology, and in particular to a pressing device for a retaining ring for a bracket bearing assembly. Background Technology
[0002] To reduce the assembly process for customers, bearings are trending towards integration, being integrated with other components in the application area, resulting in either one-piece or separate designs.
[0003] In a split design, retaining rings are required for fixation, such as in the combined bearings on existing drive shaft brackets (e.g.) Figure 1 As shown in the figure, the bearing and the bracket are fixed by a snap ring, and the installation usually relies on snap ring pliers for pressing. This requires workers to do a lot of hard work, and the timeliness is not good. The installation accuracy and efficiency are also difficult to guarantee.
[0004] Therefore, a tooling that can improve pressing efficiency and accuracy is needed. Summary of the Invention
[0005] In order to solve the problem that the installation accuracy and efficiency of existing bearing assembly methods are difficult to guarantee, this utility model provides a pressing device for snap rings that can improve pressing efficiency and accuracy.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a pressing device for a retaining spring for a bracket bearing assembly, including a bottom mold, an upper pressing mold above the bottom mold, a connecting rod fixed on the top of the upper pressing mold for connecting with a pressing device and driven by the pressing device to apply pressure to the bottom mold, an intermediate guide mold between the upper pressing mold and the bottom mold, the bottom mold for placing the bracket and providing positioning and support for the bracket, the intermediate guide mold placed on the bracket, the retaining spring placed in the intermediate guide mold and pressed into the retaining spring groove of the bracket by sliding the upper pressing mold downward.
[0007] Furthermore, a protective washer is fixed around the periphery of the intermediate guide mold, and the protective washer is in contact with the bracket.
[0008] Furthermore, the bottom shape of the intermediate guide mold matches the bracket.
[0009] Furthermore, a positioning block is also placed inside the bottom mold.
[0010] Compared with the prior art, the advantages of this utility model are:
[0011] It improves the automation level of snap ring pressing to a certain extent, reduces manual operation, reduces the labor intensity of workers, and improves the accuracy and efficiency of bearing installation through the positioning function of the bottom mold and positioning block. At the same time, the protective washer can also protect the workpiece to a certain extent. When some workpieces have coatings, it can protect the integrity of the coating, thereby improving the yield of bearings. Attached Figure Description

[0015] Figure descriptions: 1. Bottom mold; 11. Positioning block; 2. Intermediate guide mold; 21. Protective washer; 3. Upper pressure mold; 31. Connecting rod; 4. Snap ring; 5. Bracket. Detailed Implementation
[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0017] like Figure 1As shown, a pressing device for a retaining ring 4 for a bearing assembly includes a bottom mold 1. The bottom mold 1 is used to place the bracket and provide positioning and support for the bracket. The bottom mold 1 is fixed on a worktable and then positions and fixes the bracket 5 to ensure that the bracket 5 will not shift during the pressing process. An upper pressing mold 3 is provided above the bottom mold 1. A connecting rod 31 for connecting to the pressing equipment is fixed to the top of the upper pressing mold 3. The pressing equipment drives the upper pressing mold 3 to apply pressure to the bottom mold 1. The upper pressing mold 3 applies downward pressure to the bottom mold 1, pressing the retaining ring 4 into the bracket 5 placed inside the bottom mold 1. A positioning block 11 is also placed inside the bottom mold 1. The positioning block 11 can also adjust the positioning effect of the bottom mold 1 on the bracket 5 according to the different bearing sizes produced, thus accommodating bearings of different sizes. A space is also provided between the upper pressing mold 3 and the bottom mold 1. There is an intermediate guide mold 2, which is placed on the bracket 5. The retaining ring 4 is placed inside the intermediate guide mold 2 and pressed into the retaining ring groove of the bracket 5 by the upper pressing mold 3. The intermediate guide mold 2 guides the retaining ring 4 into the retaining ring groove, and at the same time, it can also provide a certain pressure buffer between the bottom mold 1 and the upper pressing mold 3, thereby providing a certain degree of protection for the workpiece and preventing damage to the workpiece, especially preventing coating wear. A protective washer 21 is fixed on the outer periphery of the intermediate guide mold 2. The protective washer 21 contacts the bracket 5 and is used to further enhance the protective effect of the intermediate guide mold 2 on the workpiece. The bottom shape of the intermediate guide mold 2 matches the bracket 5. This setting makes it easier for the intermediate guide mold 2 to enter the bracket, thereby reducing its own damage to the bracket and further ensuring the yield of bearings.
[0018] The scope of protection of this utility model includes, but is not limited to, the above embodiments. The scope of protection of this utility model is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
