Pull-out test testing device of riveting piece

Abstract

The invention discloses a pull-out test testing device of a riveting piece. The pull-out test testing device comprises an upper installation device, an upper pull-out hook, a lower installation device, a lower pull-out hook, an upper riveting piece, and a lower riveting piece, wherein both the upper pull-out hook and the lower pull-out hook have an incomplete closed 'concentric-square-shaped' structure, the upper pull-out hook is arranged on the upper installation device, the lower pull-out hook is arranged on the lower installation device, the bottom edge of the upper pull-out hook is provided with a first opening, the top edge of the lower pull-out hook is provided with a second opening, the upper riveting piece and the lower riveting piece are in cross connection through a riveting part, an inner hook body at a first opening edge of the upper pull-out hook hooks two ends of the upper riveting piece and pulls the upper riveting piece upwards, and an inner hook body at a second opening edge of the lower pull-out hook hooks two ends of the lower riveting piece and pulls the lower riveting piece downwards. A traditional pull device cannot meet test demands. The invention solves theabove problem and improves operability and efficiency of pull force test of the riveting piece.

Description

technical field [0001] The invention relates to the mechanical performance test of standard parts, in particular to a riveted part pull-off test testing device. Background technique [0002] In the field of aviation, it is necessary to use some standard parts such as blind rivets and ring groove rivets with complex structures for riveting between different sandwich materials. For these rivets, in addition to the traditional mechanical performance testing, a very important mechanical index is also tested, which is to simulate the pull-off force of the rivets after riveting with different interlayer materials, so as to provide more reliable safety guarantee for the aircraft. Since the blind rivet is an assembly with a complex structure, the traditional tension device cannot meet the test needs, so a special rivet pull-off test device is needed for the pull-off test of various sandwich materials. Contents of the invention [0003] The invention provides a device for testing ...
