Patent Application
20160195120
The subject matter herein generally relates to an coaxial assembly and an assembly method using the same.
Mechanical assembly is important in machinery manufacturing. It is common that a plurality of components are required to be coaxial. A special fixture can be used to ensure that the components are assembled coaxially.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
The present disclosure is described in relation to an coaxial assembly and an assembly method using the same.
In at least one embodiment, the number of the position members 50 can be four, and the position members 50 can be evenly distanced from each other and along a circumference of the lateral wall of the second member 30. Each position member 50 can be substantially wedge-shaped and radially extending from the lateral wall 341 of the assembly portion 34. The position member 50 can include a guiding surface 52 and an abutting end 54 at one end of the guiding surface 52.
The guiding surface 52 can be inclined to the central axis 342 of the assembly portion 34, and a distance between one end of the guiding surface 52 away from the main body 32 and the assembly portion 34 is smaller than a distance between the other end of the guiding surface 52 adjacent to the main body 32 and the assembly portion 34. The abutting end 54 can be arranged at one end of the guiding surface 52 near the main body 32.
In at least one embodiment, the position member 50 can be coupled to the assembly portion 34 by casting, welding, adhesive joints, or other mechanical joint. The position members 50 can also integrally formed with the assembly portion 34. In other embodiments, the number of the position members 50 can be two or more than two, and the position members 50 can be evenly arranged at lateral wall 341 of the assembly portion 34.
Referring to
At block 501, the first member 10 with an assembly hole 14 can be provided.
At block 502, the second member 30 with an assembly portion 34 can be provided.
At block 503, at least two position member 50 can be provided. Each position member 50 can include the guiding surface 52 and the abutting end 54. The guiding surface 52 can be inclined with the central axis 342 of assembly portion 34, and the abutting end 24 can be formed at one end of the guiding surface 52.
At block 504, the at least two position members 50 can be evenly arranged at the lateral wall 341 along circumference of the assembly portion 34.
At block 505, the assembly portion 34 can be assembled into the assembly hole 14, and the abutting ends of the position members 50 can tightly abut the sidewall 141 of the assembly hole 14, thus the second member 30 can be coaxially mounted to the first member 10.
As the position members 50 can tightly abut the sidewall 141 of the assembly hole 14 or make an interference with the sidewall 141 of the assembly hole 14, the second member 30 can be coaxially mounted to the first member 10. The assembly is simple, and the assembly process is convenient. The first member 10 can be coaxial with the second member 30. The plurality of the position members 50 can have a same size and a same structure, thus the position members 50 can have a high manufacturing accuracy. Moreover, the position members 50 can be adapted to different kinds of the first member 10 and the second member 30, thus the production cost is low.
The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of an coaxial assembly and an assembly method using the same. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, especially in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
