Titanium nail riveting device based on lateral ultrasonic energy field assistance and forming method thereof

Abstract

The invention discloses a titanium nail riveting device based on lateral ultrasonic energy field assistance and a forming method thereof. The titanium nail riveting device comprises a rack used for supporting; a clamp tooling module used for fixing objects is erected at the top end of the rack; a vertical mounting frame is arranged at one side of the clamp tooling module; the bottom end of the vertical mounting frame is connected with the rack; and the vertical mounting frame is laterally provided with an ultrasonic assistant module. The titanium nail riveting device based on the lateral ultrasonic energy field assistance is scientific and reasonable in structure and safe and convenient to use; through laterally arranging the ultrasonic assistant module, an ultrasonic generator can work normally under the riveting force of a titanium rivet instead of being abnormal under the excessive riveting force, and the maximum riveting force can be increased up to 30 KN to improve the riveting quality; and the ultrasonic energy field assistant riveting is generated through the action of the ultrasonic assistant module, and the volume effect and the surface area effect under the ultrasonic energy field are fully utilized to reduce the deformation resistance during riveting, so that the uniformity of the interference amount of riveting is effectively improved, and the riveting quality is improved.

Description

technical field [0001] The invention relates to the technical field of aircraft assembly, in particular to a titanium nail riveting device assisted by a lateral ultrasonic energy field and a forming method thereof.
