Technical Field

The invention relates to the technical field of machining, in particular to a circular ring supporting device with adjustable diameter and size.

Background

For the ring structures (including a whole ring structure and an open ring structure) commonly used in the mechanical manufacturing industry, certain deformation can be generated after machining. For example, the stress release of each point is not uniform after the thin-wall large-diameter circular ring is machined, and the thin-wall large-diameter circular ring is easy to deform; particularly, in the structure of the open circular ring, the deformation amount is larger due to stress release after the circular ring is opened. In addition, the ring parts may be deformed by falling off due to improper protection. For parts with high requirements on dimensional accuracy, the parts can be assembled after being accurately corrected. The conventional correction mode is mostly cold correction, namely, deformation is generated by single-point pressure application so as to achieve the purpose of correction; thermal calibration may be incorporated if desired; however, the conventional correction method has low correction efficiency and poor correction quality, and is not suitable for parts with higher requirements on the dimensional accuracy of products, so that a circular ring supporting device with adjustable diameter size is provided.
