AI Technical Summary

Technical Problem

Existing riveting equipment requires rotating a worm gear during riveting, which is cumbersome and makes it difficult to ensure that the riveting hole of the parts to be riveted is concentric with the rivet, resulting in poor riveting effect.

Method used

The self-centering assembly, including an elastic support assembly, a movable sleeve, an arc-shaped support plate, and a switch assembly, ensures that the riveting hole and the rivet are concentric through the elastic support of the elastic support assembly and the drive of the switch assembly, simplifying the operation and improving the riveting efficiency.

Benefits of technology

It achieves concentricity between the rivet hole and the rivet, improves the riveting effect, avoids riveting failure, and is simple and efficient to operate.

Abstract

A riveting pressing device includes a stamping platform, a stamping assembly, and a self-centering assembly. The stamping platform is equipped with the stamping assembly, and the self-centering assembly is located below the stamping assembly. The self-centering assembly includes an elastic support assembly, a movable sleeve, an arc-shaped support plate, and a switching assembly. The elastic support assembly is located on the stamping platform. The movable sleeve is movably mounted on the elastic support portion of the elastic support assembly. The movable sleeve is circumferentially arranged with arc-shaped support plates. The switching assembly is located on the movable sleeve, with its actuating end facing the stamping end of the stamping assembly. The pressing end of the switching assembly contacts the arc-shaped support plates, serving to drive all the arc-shaped support plates to move outward from the movable sleeve. By incorporating the self-centering assembly, the stamping assembly can simultaneously press downward and align the riveting hole on the workpiece with the rivet, improving the riveting effect and preventing riveting failure.
