Abstract

The invention provides a quick-release inner support device, which comprises a mandrel arranged coaxially from the inside to the outside, an inner support ring of a strut, a middle support ring, and an outer support ring. One end of the strut is connected to the mandrel, and the other end It is connected with the inner support ring, and the middle support ring is surrounded by several middle support blocks. The middle support block and the inner support ring are connected by a telescopic device. The outer support ring includes an outer support arc block and a gap adjustment pad. The outer support arc block and the gap adjustment cushion block are arranged at intervals and respectively connected with the middle support block one by one to form the outer support ring, wherein the gap adjustment cushion block and the middle support block are detachably connected. The quick-release inner support device provided by the present invention controls the expansion and contraction of the middle support ring through the expansion and contraction device, thereby controlling the outer support ring to tighten and relax the inner cavity of the workpiece.

Description

technical field [0001] The patent of the present invention relates to a quick-detachable internal support device, in particular to a quick-detachable internal support device for butt jointing of large-diameter closed circular workpieces. Background technique [0002] In the field of aerospace, there is often the butt joint production of large diameter closed ring workpieces. This kind of workpiece has small wall thickness and large diameter, and the diameter / wall thickness ratio after proportional reduction even exceeds that of ordinary pop cans. Therefore, during docking production, if there is no effective rigid support in the inner cavity of the large-diameter closed annular workpiece, it is very easy to cause deformation of the workpiece and lead to scrapping. At the same time, the workpiece is a closed ring structure, and the internal operating space is narrow. After the docking production is completed, there is only one small window for the support device to enter and...
