Abstract

The invention relates to a precise linear cutting clamping device for a titanium alloy weak-rigidity piece and a working method of the precise linear cutting clamping device, and belongs to the technical field of precise electric machining. The clamping device comprises an upper cover, an E-shaped lower cover, a positioning pin and a fixing screw. The invention provides a machining method of a modern process, which can effectively meet the requirements of the size precision, the surface roughness and the parallelism of the weak-rigidity titanium alloy thin-wall piece, and designs a precise clamping device which can be applied to slow-feeding wire cutting machining and can ensure the machining precision and the size requirement. The main content of the invention includes that the thin-wallpiece with the linear cutting allowance after a milling process is installed in the designed clamping device for a slow-feeding wire cutting process, and the technological process of thinning a wing plate of the thin-wall piece to 0.2 mm is completed. The machining precision and the surface roughness of the thin-wall piece are improved by the precise linear cutting clamping device for the titaniumalloy weak-rigidity piece; and the device is suitable for machining the special-shaped curved surface thin-wall piece which cannot be completed by a traditional process.

Description

Technical field[0001]The invention belongs to the technical field of precision electrical machining, and particularly relates to a precision wire cutting clamping device for titanium alloy weak rigid parts and a working method thereof.Background technique[0002]Thin-walled titanium alloy parts with complex structure and weak rigidity are widely used in precision instruments such as aerospace and medical equipment. Due to the poor machinability of titanium alloys, thin-walled parts with weak rigidity have low rigidity and are prone to deformation during mechanical micro-cutting. , Instability, vibration and other issues, and lead to a decline in processing accuracy. Titanium alloy thin-walled parts with weak rigidity are favored by the aerospace industry because of its high strength, good corrosion resistance, and high heat resistance.[0003]In the machining process, due to the direct contact between the tool and the part, cutting force is inevitably generated, which in turn causes the...
