Integrated detection and cutting tool for large aluminum alloy top cover component

The utility model provides an integrated detection and cutting tool for a large aluminum alloy top cover component. Wherein the central supporting ring (2), the peripheral supporting ring (3) and theplurality of intermediate supporting heads (5) are arranged on the main bracket and are used for supporting the convex surface of a top cover component (4) together; the central supporting ring (2) iscylindrical; the height of the central supporting ring and the height of the intermediate supporting head can be adjusted so as to adapt to top cover components with different forming precision, andan inner fixing hole (21) and an outer fixing hole (31) which are used for fixing the components are formed in the central supporting ring and the peripheral supporting ring respectively. The tool provided by the utility model is specially arranged for the top cover component with a hole in the center position and a spherical curved molded surface; the size error of the edges of the inner ring andthe outer ring can be measu
