Blind rivet disassembling tool and disassembling method

Abstract

The invention belongs to aircraft riveting assembly techniques and relates to a raised-head blind rivet disassembling tool and a disassembling method thereof. The raised-head blind rivet disassembling tool is characterized in that a shaft is arranged inside an inner sleeve, a limiting block is arranged at the exposed end of the shaft outside the inner sleeve through a locking screw, an outer spring is wound on the shaft inside the inner sleeve, a self-lubricating gasket and a limiting gasket are mounted on the shaft and in the position close to upper port of the inner sleeve, the inner sleeve is arranged inside a limiting sleeve, a ring-shaped cavity is formed between the inner sleeve and the limiting sleeve, an inner spring is arranged inside the ring-shaped cavity, the limiting sleeve is arranged inside a hollow fine-adjustment sleeve, and a hollow drill bit is arranged at the bottom of the shaft and positioned inside the fine-adjustment sleeve. The hollow drill bit can disassemble the head of a blind rivet without damaging the structure and then push out the remaining rivet bar, so as to complete disassembly of the blind rivet. The tool can meet the requirements for disassembling different types and diameters of raised-head blind rivets, is simple and convenient to use, is adjusted rapidly, has high disassembly efficiency and good quality, and is suitable for massive disassembly work.

Description

technical field [0001] The invention belongs to aircraft riveting assembly technology, and relates to a disassembly tool and a disassembly method for a convex head blind rivet. Background technique [0002] Because a large number of convex head blind rivets are used in aircraft structure riveting, in the production process, due to riveting failures, structural repairs and other reasons, sometimes it is necessary to disassemble a large number of convex head blind rivets. Since there is no corresponding tool, workers can only use a drill to drill out the locking ring of the rivet ejector rod, and then use a punch to punch out the ejector rod, then use a drill to disassemble the nail head and punch the nail rod with a flat-head punch to disassemble a blind rivet. [0003] However, because the material of the shank of the blind rivet is very hard, it is relatively difficult to remove the locking ring of the blind rivet, and the operation of disassembling the rivet head is relat...

AI Technical Summary

Problems solved by technology

[0003] However, because the material of the shank of the blind rivet is very hard, it is relatively difficult to remove the locking ring of the blind rivet, and the operation of disassembling the rivet head is relatively prone to failure. For experienced workers, the disassembly quality is better due to experience and accurate techniques, but It is not easy for new workers to master, and when a large amount of decomposition work is performed, the efficiency is low and quality accidents are prone to occur.
