The invention belongs to the technical field of material machining, and particularly relates to an ancillary supporting device for machining a thin-wall revolving member and a using method for the ancillary supporting device. At present, effective supporting of a revolving thin-wall composite material member is difficult to achieve, so that layered damage is extremely prone to generation at a manufactured hole outlet, and the machining accuracy is difficult to guarantee; according to the ancillary supporting device, effective supporting in the manufactured hole machining process of the thin-wall revolving member is achieved, and workpiece deformation caused by manufactured hole machining cutting force is prevented; and meanwhile, accurate supporting of a manufactured hole outlet zone is achieved, and the possibility of layering generated on the thin-wall revolving member made of a composite material is lowered. Ancillary supporting machining of holes in multiple positions of the revolving member in the peripheral direction is achieved through a machine tool revolving working table and an ancillary revolving working table. A measuring cell is adopted for measuring the cutting axial force and the supporting force, and accurate control over the supporting force of the ancillary supporting device is achieved.
Description
technical field [0001] The invention belongs to the technical field of material processing, and in particular relates to an auxiliary supporting device for processing thin-walled rotary components and a method for using the same. Background technique [0002] Thin-walled components have processing requirements in many fields, especially in the aerospace field, there are a large number of thin-walled rotary components. During the machining of thin-walled rotary components, the machining accuracy is usually difficult to guarantee because the structural parts are prone to serious machining deformation under the action of cutting force. [0003] In the field of aerospace, non-metallic components such as resin composite materials are increasing. The rigidity of non-metallic components is low, and the deformation problem during processing is more serious. Among the existing processing requirements, aerospace structural parts have a large demand for hole-making processing, and th...
