AI Technical Summary

Technical Problem

During the assembly process, existing rivet bolts suffer from gaps between the nut and the bolt, causing the bolt to tilt and become eccentric, which affects the connection accuracy and stability.

Method used

A high-precision positioning rivet bolt is designed. By setting a slider on the bolt part, it is made to fit or be close to the inner wall of the deformed part of the rivet nut, ensuring coaxial positioning during the riveting process. The axial guidance and limiting are achieved by the cooperation between the slider and the deformed part, reducing the eccentricity phenomenon.

Benefits of technology

It improves the coaxiality and assembly accuracy between bolts and nuts, ensures a smooth riveting process, enhances the stability and reliability of the connection, and has good maintainability and assembly capabilities.

Abstract

The utility model discloses a high accuracy positioning pull rivet bolt and connecting structure, including pull rivet nut, pull rivet nut includes main part and flange, the main part has pull rivet part and with pull rivet part connects deformation part, the flange is around and is located the outer peripheral surface of the end of deformation part away from pull rivet part, bolt part, the bolt part has the slider of can be opposite pull rivet nut along the axial movement, the inside wall of slider's outside wall and deformation part is close or adjacent arrangement, the first connecting part of slider's one end extension with pull rivet part is connected to pull rivet part, the second connecting part of slider's one end extension is opposite pull rivet part. High accuracy positioning pull rivet bolt and connecting structure of the utility model, the inside close of slider and deformation part, thereby make pull rivet nut in pull rivet process, bolt part is not easy to tilt, and then improve the position accuracy of pull rivet bolt.
