A radial support device

Abstract

The invention discloses a radial supporting device, and belongs to the technical field of processing of annular thin-wall parts. The radial supporting device comprises a base and at least two supporting mechanisms fixed to the base, wherein an annular thin-wall part placing zone is arranged on the base; the at least two supporting mechanisms are arranged at intervals in the circumferential direction of the annular thin-wall part placing zone; the supporting mechanisms comprise brackets, screws, expansion blocks and guide pillars; the brackets comprise cross plates and vertical plates; the cross plates are fixedly connected on the base; the vertical plates are vertically fixed to the cross plates; through holes and threaded holes are formed in the vertical plates; the guide pillars are movably inserted into the through holes; first sides of the expansion blocks are fixed to one ends of the guide pillars; the screws are in threaded connection with the vertical plates through the threaded holes; one ends of the screws are propped against the first sides of the expansion blocks; and support surfaces propped against the side walls of the annular thin-wall parts are arranged on second sides of the expansion blocks. According to the radial supporting device, the annular thin-wall parts can be supported during the machining process, and coaxiality of flanges at the two ends of the annular thin-wall parts can be adjusted.

Description

technical field [0001] The invention relates to the technical field of processing annular thin-walled parts, in particular to a radial support device. Background technique [0002] Thin-walled parts are widely used in automobiles, aerospace and other fields. Gas turbine support shells, casings and streamline guides are all annular thin-walled parts. These parts have large diameters and thin walls, and their axial dimensions can reach 1.5 meters. Left and right, the rigidity of machining is poor. When manufacturing such annular thin-walled parts, the thin-walled parts are usually formed by high-speed spinning, rolling, rolling, expanding and other processing technologies, and then the two ends of the thin-walled parts are processed to ensure that the thin-walled parts The two ends of the welding flange meet the size requirements of the welding flange, and then use electron beam welding to weld the flange at both ends of the thin-walled part to form a ring-shaped thin-walled ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem of poor coaxiality of the flanges at both ends of the ring-shaped thin-walled parts, and the problems of vibration and deformation that are prone to occur during machining, the embodiment of the present invention provides a radial support device
