An auxiliary machining device preventing cutting deformation of a thin-wall space curved face part is characterized by comprising a front end clamp head, a rear end clamp head, an auxiliary support assembly and an auxiliary support sample plate, wherein the front end clamp head and the rear end clamp head are combined with the auxiliary support assembly as a whole, and the auxiliary support sample plate is arranged on the auxiliary support assembly through a spring and a support. The auxiliary machining device has the advantages that machining of basin profiles and back profiles is carried out through one-shot clamping of a van, a vane program coordinate system and vane locating do not change, theoretically, errors of clamping standards do not exist, and machining position errors between a basin and a back do not exist. During machining, the profiles are not in a large-span hanging arm machining state. Therefore, rigidity is enhanced, deformation is controlled, and machining precision is greatly improved.
Description
[0001] technical field [0002] The invention relates to the field of mechanical processing, in particular to an auxiliary processing device for preventing cutting deformation of thin-walled space curved surface parts. Background technique [0003] At present, CNC machining of blades of aero-engines and gas turbine compressors mainly adopts CNC helical milling or one-way CNC milling of pots and backs. During processing, the blades are in a cantilever state, which has a great influence on cutting deformation, slow cutting speed, and low processing efficiency. , the existing support has poor ability to ensure the position accuracy between the blade basin and the back surface, and the processing and adjustment are time-consuming. Contents of the invention [0004] The purpose of the present invention is to provide an auxiliary processing device for preventing cutting deformation of thin-walled space curved surface parts in order to ensure processing accuracy and save man-hour...
