[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The utility model discloses a lightweight, precise and slender shaft, which comprises a hollow roller shaft. Two ends of the hollow roller shaft are respectively provided with a left plug and a right plug, which are arranged concentrically with the hollow roller shaft.

[0007] Furthermore, the left plug and the right plug are respectively interference fit with the two end surfaces of the hollow roller shaft.

[0008] Furthermore, a through hole for exhaust is opened at the center of the left plug.

[0009] Furthermore, a reinforced lining is installed in the hollow roller shaft.

[0010] The beneficial effects achieved by the utility model are: light weight, convenient disassembly and assembly, strong repeatability and consistency, high mechanical strength, high precision, long service life, etc., can be used at high speeds, greatly improve production efficiency, reduce manufacturing costs, and can be installed on a variety of equipment for operation.

[0014] In the figure: 1. hollow roller; 2. left plug; 3. right plug. DETAILED DESCRIPTION

[0015] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0016] Example 1

[0017] like Figure 1-2 As shown, a lightweight precision slender shaft comprises a hollow roller shaft 1, and two ends of the hollow roller shaft 1 are respectively provided with a left plug 2 and a right plug 3.

[0018] Assembly process: interference fit the left plug 2 on the left end assembly surface of the concentrically arranged hollow roller 1; heat the hollow roller 1, install the reinforced lining, and process the reference surface; then interference fit the right plug 3; use end face welding to reinforce the workpiece structure; after the assembly is completed, its accuracy is controlled by mechanical processing technology, and a through hole is reserved in the center of the left plug 2 as an exhaust hole; perform a dynamic balance test on the hollow roller 1; and finally the processing is completed.

[0019] It should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein by equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention. The terms used in the description of this application are only for describing specific implementations, and are not intended to limit the exemplary implementations according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and devices known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, the techniques, methods and devices should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0020] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0021] It should be noted that, in the description of the present application, the orientation or positional relationship indicated by terms such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise stated, these orientation words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present application; the orientation words "inside and outside" refer to the inside and outside relative to the contour of each component itself.
