Abstract
Description
Technical Field
[0001] The utility model belongs to the field of mechanical manufacturing, and in particular relates to a vertebral body supporting tool with a locking function. Background Art
[0002] With the continuous development of the modern machinery manufacturing industry, thin-walled parts have been widely used in aerospace, automobile manufacturing and other fields due to their light weight and compact structure. Among them, there are a large number of thin-walled parts with extremely low rigidity in aircraft engine components, such as blades and casings. These parts are prone to deformation during processing due to their complex appearance. Therefore, special tooling is required for support during positioning, installation or maintenance to reduce the problem of thin-wall deformation and improve the accuracy of subsequent processing steps. For thin-walled parts with specific conical shapes, the existing support tooling is simple and easy to move the conical parts during the support process. At this time, the operator needs to manually adjust the parts and reposition them. At the same time, due to frequent adjustments, the tooling is prone to wear and failure, which increases the frequency of tooling replacement. Utility Model Content
[0003] To address the above-mentioned drawbacks, the present invention aims to provide a vertebral support fixture with a locking function. By introducing a locking mechanism, the fixture improves stability during use, reduces manual adjustments, and reduces wear and tear over extended use, thus reducing the frequency of fixture replacement.
[0004] In order to achieve the above technical objectives, the following technical solutions are adopted:
[0005] A vertebral support tool with a locking function, comprising an upper vertebral body, a lower vertebral body, a limiting screw, a clamping screw and a guide column; the upper vertebral body and the lower vertebral body are hollow frustum structures and the annular large end faces of the two are symmetrically arranged outward; multiple limiting screws are threadedly connected to the annular small end face of the upper vertebral body and their ends penetrate the annular small end face of the upper vertebral body and then press on the annular small end face of the lower vertebral body, which is used to limit the distance between the upper vertebral body and the lower vertebral body; multiple clamping screws are movable through the annular small end face of the upper vertebral body and then threadedly connected to the annular small end face of the lower vertebral body, and the upper vertebral body is pressed down by spirally rotating the clamping screw to tighten the processed parts; multiple guide columns are installed on the annular small end face of the lower vertebral body and pass through the annular small end face of the upper vertebral body.
[0006] Furthermore, the limit screw is provided with a matching fixing nut and a screw sleeve; the fixing nut is used to fix the maximum length of the limit screw that can be extended into the area between the upper vertebral body and the lower vertebral body; the screw sleeve is fixed on the annular small end face of the upper vertebral body and cooperates with the limit screw thread.
[0007] Furthermore, the outer conical surfaces of the upper vertebral body and the lower vertebral body fit the positioning surfaces of the processed parts.
[0008] The beneficial effects achieved by the utility model are:
[0009] The utility model vertebral support fixture connects the upper and lower vertebral support seats into a double vertebral structure support fixture by introducing a locking mechanism composed of a limit screw, a clamping screw and a guide column. The outer conical surfaces of the upper and lower vertebral support seats fit the positioning reference surface of the processed parts. During the installation or maintenance of the parts, a stable support frame or bracket is constructed to withstand and evenly distribute the force applied to the vertebral body. The introduction of the locking mechanism can ensure that the vertebral body remains stable and does not move during the support process, and the height of the fixture can be adjusted to accommodate vertebral parts of different sizes. It reduces the additional operating requirements for the operator and improves the convenience and efficiency of the operation. The user can adjust and fix the vertebral body more easily, eliminating the trouble of manual adjustment and repositioning. At the same time, it can reduce the wear and failure of the fixture during long-term use, and improve its durability and reliability. This design can ensure that the fixture can still maintain good working condition after long-term use, reducing the frequency of maintenance and replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The upper vertebral body 1 and the lower vertebral body 2 are hollow frustum structures, and the upper vertebral body annular large end face 12 and the lower vertebral body annular large end face 22 are symmetrically arranged outward. The outer conical surface 13 of the upper vertebral body and the outer conical surface 23 of the lower vertebral body are used to fit the positioning reference surface of the processed part 8. The reference surface is the same as that of the next process, and no repeated clamping is required during processing.
[0018] Multiple limit screws 3 are threadedly connected to the annular small end face 11 of the upper vertebra and their ends penetrate the annular small end face 11 of the upper vertebra and press against the annular small end face 21 of the lower vertebra, which are used to limit the distance between the upper vertebra 1 and the lower vertebra 2; the multiple limit screws 3 are also provided with matching fixing nuts 6 and screw sleeves 7; the fixing nut 6 is used to fix the maximum length of the limit screw 3 that can be extended into the area between the upper vertebra 1 and the lower vertebra 2; the screw sleeve 7 is fixed on the annular small end face 11 of the upper vertebra and is threadedly matched with the limit screw 3.
