Supersonic vibration spin riveting machine

Abstract

The invention discloses a supersonic vibration spin riveting machine. The supersonic vibration spin riveting machine comprises an upper riveting head (16) which is connected with an amplitude transformer (17). The supersonic vibration spin riveting machine is characterized in that the amplitude transformer (17) is connected with a high frequency transducer (18), and the high frequency transducer (18) is installed in an inner sleeve (21); the inner sleeve (21) is installed in a cylindrical lower bearing pedestal (11) and connected with a connecting end base (10), the connecting end base (10) is connected with the lower end of a main shaft (4), and the upper end of the main shaft (4) is connected with a motor (1); a first electricity collecting ring (7) is installed in the middle of the main shaft (4) and connected with a first wire (9) and an outer guide line through a carbon brush (8) and transmits high frequency electrical signals obtained from an ultrasonic generator; and a second electricity collecting ring (13) transmits the high frequency electrical signals of the first electricity collecting ring (7) to the transducer (18) through a second wire (12), so that the transducer (18) generates high frequency mechanical vibration to drive the amplitude transformer (17) to do high-frequency vibration. By means of the supersonic vibration spin riveting machine, the riveting force can be reduced, and the riveting efficiency can be improved.

Description

technical field [0001] The invention relates to a riveting device, in particular to a riveting device with movement in four directions, in particular to an ultrasonic vibration riveting machine. Background technique [0002] As an important mechanical connection method, riveting is widely used in modern industrial assembly. In recent years, with the development of the aviation industry and material science, the application of aerospace materials represented by titanium alloys has become more and more extensive. A distinctive feature of this type of material is that it is difficult to deform. Traditional riveting technology is riveting titanium alloys and When representing aviation materials, not only the riveting efficiency is low, but also the riveting quality cannot be guaranteed. [0003] The electromagnetic riveting technology proposed to solve the riveting problem of such difficult-to-machine materials belongs to adiabatic shear deformation. Due to the extremely short...
