Abstract
The invention relates to a pressure riveting device. The pressure riveting device comprises a direct driving motor, a driving rod, nuts and a pressure riveting head assembly. The direct driving motoris provided with a stator and a rotor which are matched with each other, and the stator is located on the periphery of the rotor so as to be used for driving the rotor to rotate. The driving rod is provided with a driving portion fixedly connected to the rotor, and a lead screw portion located outside the direct driving motor; the driving rod is provided with a rotating axis, and the driving rod can be driven by the direct driving motor to rotate around the rotating axis. The nuts are operatively mounted to the lead screw portion of the drive rod, and is configured to axially move along the lead screw portion in response to the rotation of the driving rod around the rotating axis. The pressure riveting head assembly is fixedly connected to the nuts, and is configured to move along the axial direction of the lead screw portion along with the nuts, so that pressure riveting treatment is carried out.
Description
technical field [0001] The present application relates to riveting technology, and more specifically, to a riveting device. Background technique [0002] Pressure riveting is a riveting method that uses the static pressure generated by the riveting machine to upset the rivet rod to form an upset head. The riveted parts of pressure riveting have the characteristics of good surface quality, small deformation and high connection strength, so they are widely used in various mechanical processing fields, such as shipbuilding and automobile manufacturing. However, in some processing environments, the internal space of the workpiece to be processed is limited, and the traditional riveting device usually has a long axial length, so it is not suitable for operating in such a narrow working space. Contents of the invention [0003] The present application provides a riveting device with a relatively short axial length, which is suitable for operation in a narrow working space. [...
