Embodiment Construction

[0050] The threaded blind rivet of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0051] Such as figure 1 , figure 2 As shown, the threaded blind rivet includes: a nail shank 1 with a limit cap 1c, a drive ring 3 threaded on the nail shank 1, and a sleeve set on the nail shank 1 and located on the limit cap 1c and the drive ring 3 between nail sets 2.

[0052] Such as figure 1As shown, there is a broken neck groove 1b on the nail rod 1, and one side of the broken neck groove 1b is the driving section 1a twisted off after installation (the length of the driving section 1a is L1), and the other side is the riveting section (the length of the riveting section L2), the limit cap 1c is located on the riveting section and adjacent to the broken neck groove 1b, and the end of the riveting section away from the limit cap has an external thread that matches the drive ring 3 .

[0053] During the riveting process, the drivin...

Abstract

The invention discloses a thread core-pulling rivet and a riveting method using the same. The thread core-pulling rivet comprises a rivet rod with a limiting cap, a driving ring mounted on the rivet rod in a threaded mode and a rivet sleeve arranged on the rivet rod in a sleeving mode and located between the limiting cap and the driving ring. A blocking head matched with the limiting cap in an abutting mode is arranged at one end of the rivet sleeve, and the other end of the rivet sleeve and the driving ring are matched circumferentially in a positioned mode. In riveting, the rivet rod rotatesrelative to the rivet sleeve, the driving ring and the limiting cap apply force to the rivet sleeve oppositely to enable the rivet sleeve to be deformed, and after riveting, a deformed part of the rivet sleeve and the blocking head abut against the two sides of a riveting part. The thread core-pulling rivet has high pre-tightening force, tensile strength and fatigue strength after being mounted and is easy to assemble, so that the manufacturing difficulty and cost are reduced.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to a threaded blind rivet and a riveting method thereof. Background technique [0002] At present, a large number of new composite materials are used in aircraft manufacturing in the world, but because composite materials will cause contact electrochemical corrosion with fasteners made of aluminum and steel, major aircraft manufacturers gradually tend to use Corroded titanium and titanium alloy fasteners. [0003] The single-sided riveted fasteners suitable for the closed parts of the aircraft mainly have two structural forms, one is the pull type, and the other is the thread type. Single-sided threaded blind rivets are specially designed for the assembly of composite structural parts. Compared with pull-out blind rivets, they have the advantages of high pre-tightening force, high tensile strength and high fatigue strength. Titanium alloy threaded blind rivets combine the above ...
