Large-diameter nonmetal skin turning device

Abstract

The invention relates to the field of large launcher tail section skin outer circle machining, in particular to a large-diameter nonmetal skin turning device. The large-diameter nonmetal skin turningdevice comprises a blank body, an upper end plate, a pedestal set, a bottom plate, an upper pressing plate set, a lower pressing plate set and a fastening device set. The blank body is of a hollow cylindrical structure which is vertically placed, and the upper end plate is of a circular plate structure and is concentrically fixedly mounted at the axial top end of the blank body. The bottom plate is of a ring structure and is concentrically fixedly mounted at the axial bottom end of the blank body, and the pedestal set is fixedly mounted on the connecting position of the blank body and the bottom plate. The outer wall of the blank body is wrapped with an outer skin structure, and the upper pressing plate set is fixedly mounted on the side wall of the top end of the outer skin structure. Thelower pressing plate set is fixedly mounted on the side wall of the bottom end of the outer skin structure, and the side wall of the outer skin structure is sleeved with the fastening device set. According to the large-diameter nonmetal skin turning device, the current impending technological problem of tail section skin outer circle turning is solved, and essential data and design thoughts are provided for machining tools needed in the subsequent new model development process.

Description

Technical field [0001] The invention relates to the field of external machining of a large-scale carrier rocket tail section skin, in particular to a large-diameter non-metallic skin turning processing device. Background technique [0002] The tail section of the large launch vehicle is made of non-metallic materials with four cylindrical structures with a centripetal angle of 90°, a diameter of Ф4996mm and a height of 2624mm. The turning method is the most reliable method for forming the outer circle of the tail section of the launch vehicle at this stage. This project is mainly aimed at the turning of the outer circle of the tail section of the large-scale launch vehicle, and the design of machining tooling. In view of the large diameter, small thickness, and easy deformation of the skin of the tail section of a large carrier rocket, the fixed tooling during the outer-circle turning of the skin not only needs to cooperate with the inner surface of the skin to prevent deformati...
