Description

Technical Field

[0001] The utility model belongs to a tool fixture and particularly discloses a quick-change tool for processing large-scale thin-wall titanium alloy retaining ring series parts. Background Art

[0002] Large, thin-walled retaining rings have dimensions exceeding 370mm (Ø370mm) and a wall thickness of 3.8mm, representing 97 times the wall thickness. These large, thin-walled retaining rings are made of titanium alloy, making them challenging to machine. The aperture of such large, thin-walled rings is typically assembled with a counterpart and welded together to a tolerance of ±0.076mm. This exceptionally high precision is crucial to the part's assembly function and is a common feature of this product line.

[0003] Traditional processing methods for this characteristic mostly use three-jaws with a large contact area to clamp parts. These parts are prone to deformation during turning and require repeated correction of the center position of the parts before processing. This results in very low production efficiency and makes it difficult to ensure the stability of product quality. Summary of the Invention
