[0002] The existing inner and outer rings of bearings and the corresponding holes and shafts all have high-requirement matching dimensions and high assembly requirements. Improper installation can easily cause surface damage to components. Deformable parts such as inner and outer rings of bearings may also cause uneven deformation due to uneven force, affecting the matching properties of components, the functional requirements of components, and the interchangeability of components. There are also certain safety hazards. Utility Model Content

[0003] In view of this, the utility model aims to propose a mounting structure and casting processing equipment for bearing installation, so as to solve the problem that improper installation of existing bearings can easily cause surface damage to parts, and deformable parts such as inner and outer rings of bearings may also cause uneven deformation due to uneven force.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A mounting structure for mounting a bearing comprises a plug and a bearing, wherein the center of the plug is matched and connected with the inner wall of the inner ring of the bearing, and the two ends of the plug are fitted with the top of the outer ring of the bearing.

[0006] Furthermore, the diameter of the central portion of the plug is smaller than the inner ring diameter of the bearing.

[0007] Furthermore, the diameter of the outer ring of the plug is smaller than the diameter of the outer ring of the bearing.

[0008] Furthermore, the plug adopts a convex structure.

[0009] Furthermore, the central raised portion of the plug is partially rounded.

[0010] Furthermore, there is a gap between the center of the plug and the inner ring of the bearing.

[0011] Furthermore, a casting processing equipment includes a mounting structure for mounting a bearing.

[0012] Furthermore, the bearing is installed in the casting.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. When assembling the utility model, the bottom of the casting and the pressure head of the plug are ensured to be parallel to the ground, so that the bearing can be pressed into the bearing hole along the axis during installation, and a higher assembly accuracy can be ensured.

[0015] 2. The diameter of the central part of the plug of the utility model is smaller than the inner ring diameter of the bearing. There is a gap between the center of the plug and the inner ring of the bearing, so that the plug can be easily pulled out after being inserted into the inner ring of the bearing, avoiding the formation of a closed gas compression space during the installation process, which makes it impossible to remove the tool.

[0016] 3. The rounded corner design of the central raised part of the plug of the utility model can easily guide the plug into the inner ring of the bearing without damaging the inner ring of the bearing.

[0017] 4. The diameter of the outer ring of the plug of the utility model is smaller than the diameter of the outer ring of the bearing, so that the bearing can be installed in a deeper bearing hole. Since a certain gap is formed between the outer ring of the plug and the hole, it is convenient to pull out the plug.

[0018] 5. The plug of the utility model has a simple structure, and the sizes requiring high precision are few. A set of assembly plugs corresponding to the bearing can be easily processed according to the standard inner and outer rings of the bearing, and the use cost is low.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely explain the technical solutions in the embodiments of the utility model. It should be noted that the embodiments and features in the embodiments of the utility model can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0023] See also Figure 1 The present embodiment is described as a mounting structure for mounting a bearing, characterized in that it includes a plug 2 and a bearing 5, wherein the center position of the plug 2 is matched and connected with the inner wall of the inner ring 4 of the bearing 5, and the two ends of the plug 2 are fitted with the top of the outer ring 3 of the bearing 5.

[0024] The diameter of the central portion of the plug 2 is smaller than the diameter of the inner ring 4 of the bearing 5 .

[0025] The diameter of the outer ring of the plug 2 is smaller than the diameter of the outer ring 3 of the bearing 5 .

[0026] The plug 2 adopts a convex structure.

[0027] The central raised portion of the plug 2 is partially rounded.

[0028] There is a gap 6 between the center of the plug 2 and the inner ring of the bearing 5 .

[0029] The plug 2 of the device adopts a convex structure design, which has a simple structure and is easy to process. It can be processed and used as a set with low cost. A certain gap 6 is formed between the center of the plug 2 and the inner ring 4 of the bearing 5 to facilitate the introduction of the plug 2 without damaging the inner ring 4. Since the gap 6 is formed during assembly, it will not be difficult to disassemble due to compressed enclosed air, which solves the problem that improper installation of the existing bearing 5 easily causes surface damage to components. The deformable parts such as the inner and outer rings of the bearing 5 may also cause uneven deformation due to uneven force, which affects the matching properties of the components, the functional requirements of the components, and the interchangeability of the components, and there are certain safety hazards.

[0030] The diameter of the central part of the plug 2 is smaller than the diameter of the inner ring 4 of the bearing 5. There is a gap between the center of the plug 2 and the inner ring 4 of the bearing 5, so that the plug 2 can be easily pulled out after being inserted into the inner ring 4 of the bearing 5, avoiding the formation of a closed gas compression space during the installation process, which makes it impossible to remove the tool. The outer ring diameter of the plug 2 is smaller than the diameter of the outer ring 3 of the bearing 5, so that the bearing 5 can be installed in a deeper bearing hole. Since a certain gap is formed between the outer ring of the plug 2 and the hole, it is convenient to pull out the plug.

[0031] The plug 2 has a simple structure, and the dimensions with high precision requirements are few. According to the standard inner and outer rings of the bearing 5, a set of corresponding assembly plugs 2 can be easily processed, and the use cost is low.

[0032] A casting processing device comprises a mounting structure for mounting a bearing, wherein the bearing 5 is mounted in a casting 1.

[0033] During assembly, ensure that the bottom of the casting 1 and the pressure head of the plug 2 are parallel to the ground, so that the bearing 5 can be pressed into the bearing hole along the axis during installation, which can ensure high assembly accuracy. When the pressure is large, use a hydraulic press to press it in, and when the size is small, use a bench vise to press it in.

The embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. According to the content of this specification, many modifications and changes can be made.
