Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of eccentric shaft processing, in particular to an eccentric shaft processing tool. Background Art
[0002] As an important mechanical transmission element, the eccentric shaft plays a key role in various types of mechanical equipment. However, due to the particularity of its structure with two sections of cylindrical eccentricity, the processing of the eccentric shaft has always been a technical problem. However, traditional eccentric shaft processing tooling often has problems such as complex structure, cumbersome operation, and low precision, which makes it difficult to meet the modern machinery manufacturing industry's demand for high precision and high efficiency. Therefore, the development of a new type of eccentric shaft processing tooling is of great significance for improving the processing quality of eccentric shafts, reducing production costs, and improving production efficiency. Defects and shortcomings of the prior art: Due to the structural characteristics of the lathe, ordinary CNC lathes can only process parts with the same rotation center, which must be consistent with the rotation center of the lathe spindle. How to change the rotation center of the spindle is the problem to be solved by this application. Summary of the invention
[0003] The utility model aims to provide an eccentric shaft processing tool, which is intended to solve the problem of eccentric shaft processing.
[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows:
[0005] An eccentric shaft processing tool comprises a columnar eccentric sleeve body, the eccentric sleeve body is provided with a through hole, the through hole is eccentrically arranged with respect to the eccentric sleeve body; the eccentric sleeve body is provided with a first through groove and a second deformation groove along the diameter direction of the through hole; auxiliary positioning columns are arranged on both sides of the through hole.
[0006] On the basis of the above solution and as a preferred solution of the above solution: two auxiliary positioning columns are symmetrically arranged.
[0007] On the basis of the above solution and as a preferred solution of the above solution: the end of the auxiliary positioning column has a tapered end.
[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the width of the first through groove and the second deformation groove is 2 mm.
[0009] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects: the eccentric sleeve body is provided with an eccentric through hole that matches the outer circle of the eccentric sleeve body, and the eccentric size is consistent with the eccentric size of the eccentric shaft; of course, in order to further realize the rapid positioning of the position of the eccentric shaft, an auxiliary positioning column is set, and one end of the eccentric shaft is inserted into the through hole, and the other end of the eccentric shaft is partially abutted on the auxiliary positioning column, so as to realize that the axis of the end of the eccentric shaft is coaxial with the eccentric sleeve body within the required tolerance range. The eccentric shaft is inserted into the through hole of the eccentric sleeve body, and after being positioned by the auxiliary positioning column, the eccentric sleeve body is clamped by a three-jaw chuck. Since the surface of the eccentric sleeve body is provided with a first through groove and a second deformation groove, the eccentric sleeve body will produce elastic deformation while being clamped and squeezed by the three-jaw chuck, and the through hole will clamp the eccentric shaft, thereby realizing clamping and positioning, so as to realize the precise positioning of the eccentric shaft.

[0016] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
[0017] See Figure 1-4As shown, the present application discloses an eccentric shaft processing tool, including a columnar eccentric sleeve body 10, a through hole 11 is provided on the eccentric sleeve body 10, and the through hole 11 is eccentrically arranged with the eccentric sleeve body 10; the eccentric sleeve body 10 is provided with a first through groove 12 and a second deformation groove 13 along the diameter direction of the through hole 11, and in this embodiment, the width of the first through groove 12 and the second deformation groove 13 is preferably 2 mm, while ensuring the strength of the eccentric sleeve body 10, the deformation size of 2 mm can fully ensure the deformation required during clamping. Auxiliary positioning columns 14 are provided on both sides of the through hole 11. In this embodiment, preferably, two auxiliary positioning columns 14 are symmetrically arranged. Through the two auxiliary positioning columns 14 cooperating with the through hole 11, after the first shaft section 21 of the eccentric shaft 20 is inserted into the through hole 11, the two auxiliary positioning columns 14 contact the outer peripheral surface of the eccentric portion 22 of the eccentric shaft 20 to achieve rapid positioning of the eccentric shaft 20, at which time the axis of the eccentric shaft section 23 coincides with the axis of the eccentric sleeve body 10, achieving rapid positioning of the eccentric shaft. It is further preferred that the end of the auxiliary positioning column 14 has a tapered end 141, and the tapered section 141 facilitates the eccentric portion 22 to be smoothly inserted between the two auxiliary positioning columns 14, thereby facilitating rapid positioning of the eccentric shaft 20.
[0018] Specifically, the working principle of the present application is as follows: the eccentric sleeve body is provided with an eccentric through hole that matches the outer circle of the eccentric sleeve body, and the eccentric size is consistent with the eccentric size of the eccentric shaft; of course, in order to further realize the rapid positioning of the position of the eccentric shaft, an auxiliary positioning column is set, and one end of the eccentric shaft is inserted into the through hole, and the other end of the eccentric shaft is partially abutted on the auxiliary positioning column, so as to realize that the axis of the end of the eccentric shaft is coaxial with the eccentric sleeve body within the required tolerance range. The eccentric shaft is inserted into the through hole of the eccentric sleeve body, and after being positioned by the auxiliary positioning column, the eccentric sleeve body is clamped by a three-jaw chuck. Since the surface of the eccentric sleeve body is provided with a first through groove and a second deformation groove, the eccentric sleeve body will produce elastic deformation while being clamped and squeezed by the three-jaw chuck, and the through hole will clamp the eccentric shaft, thereby realizing clamping and positioning, so as to realize the precise positioning of the eccentric shaft, and then facilitate the high-precision clamping and processing of the eccentric shaft by the lathe.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
