Technical Field

[0001] This utility model relates to the field of riveting equipment technology, and in particular to a device for facilitating the riveting of rear longitudinal beams. Background Technology

[0002] The chassis is the most important load-bearing component in a car, and the longitudinal beams of the chassis are one of the key parts. The longitudinal beams are usually stamped from low alloy steel plates, and the cross-sectional shape is generally channel-shaped, but some are made into Z-shaped or box-shaped cross-sections. The longitudinal beams can be divided into front longitudinal beams and rear longitudinal beams according to their distribution position. The rear longitudinal beams generally use channel-shaped or box-shaped cross-sections. In order to facilitate the installation of other components on the rear longitudinal beams, rivet nuts are riveted to the rear longitudinal beams by press riveting.

[0003] Currently available rear longitudinal beam riveting equipment can only rivet a certain type of rear longitudinal beam, and switching the riveting surface is quite troublesome, which reduces the efficiency of rear longitudinal beam riveting. At the same time, since different nuts are used for different riveting surfaces, workers are prone to making mistakes when riveting the rear longitudinal beam, which will reduce the quality of rear longitudinal beam riveting.

[0004] Therefore, there is an urgent need to provide a device that facilitates the riveting of the rear longitudinal beam to solve the above problems. Utility Model Content
