Embodiment Construction

[0021] figure 1 A first variant of a vibratory riveting tool is shown.

[0022] Wherein, the vibration riveting tool 1 includes: a rivet container 2 for accommodating a rivet 3 and a driving unit 4 . The drive unit 4 generates a considerable purely mechanical static pressure 5 which acts substantially parallel to the longitudinal axis 6 of the rivet. In order to facilitate the process of pressing the rivet 3 into the component hole 7 in the component 8, vibration generators 9, 10 for generating mechanical vibrations 11 are arranged in the area of ​​the rivet container 2, the amplitude of which vibration is equal to the static pressure 5 overlay. exist figure 1 In the exemplary embodiment shown, the vibration generators 9 , 10 are arranged diametrically opposite one another in the region of the rivet container 2 . In principle, it is also possible to arrange the vibration generator 9 or the vibration generator 10 only on one side of the rivet container 2 . Furthermore, mor...

Abstract

The rivet tool (1) has a rivet retainer (2) and a drive unit (4), where the drive unit produces a static press-in force (5) in a direction of a rivet longitudinal axis (6). A vibration sensor (9) is provided for producing a mechanical vibration (11), and the static press-in force is overlaid by an amplitude of the mechanical vibration. The amplitude of the vibration runs parallel and / or transverse to the rivet longitudinal axis, and works in a direction of the longitudinal axis. A frequency of the vibration is steplessly adjustable, where the vibration sensor is a piezoelectric element. An independent claim is also included for a method for pressing and fastening of rivets into components drillings of components of aircraft.

Description

technical field [0001] The invention relates to a vibratory riveting tool for pressing and fastening rivets into component bores of components, in particular aircraft components, the vibratory riveting tool having a rivet container and a drive unit, the drive unit being positioned at the longitudinal axis of the rivet static pressure in the direction. Background technique [0002] Known embodiments of vibratory riveting tools and riveting hammers in aircraft construction use considerable mechanical force, especially acting in the axial direction of the rivet, to press the rivet into the rivet hole. In this case, the riveting tool must exert a force weighing up to one metric ton (approximately 10 kN). Due to the considerable force required to press rivets, riveting tools must be configured to be relatively large and heavy. Therefore, in the case of automated riveting for connecting components, riveting machines weighing up to one metric ton are required. [0003] More adva...
