AI Technical Summary

Technical Problem

Existing door hinge quality inspection devices are unable to accurately control the impact force, resulting in inaccurate test results and the risk of door damage. They are also difficult to simulate actual usage conditions and cannot accurately evaluate hinge performance.

Method used

A quality inspection device for automobile door hinges was designed. The door is stabilized by a vacuum adsorption device, and combined with a swing and auxiliary buffer mechanism, the opening and closing action of the door is simulated to ensure that the door swings at a uniform and stable speed. The smoothness is observed to judge the hinge performance.

Benefits of technology

It improves the accuracy and reliability of test results, reduces damage to vehicle doors and equipment, and can more accurately measure the resistance and torque parameters of hinges at different angles, providing more reliable quality judgments.

Abstract

The present application relates to hinge quality inspection technical field, specifically, it is a kind of automobile door hinge quality inspection device. Including base, the upper side of the base is fixedly connected with bottom plate, one side of the bottom plate is fixedly connected with side plate, the side plate one side is provided with door, the side plate one side and door are fixedly connected by two hinge bodies, the present application is by vacuum force and is adsorbed in the one side of door by multiple suction cups, exerts a relatively stable force on door, ensure the accuracy of subsequent door swing angle, then swing door in different angle range by swing lever, truly simulate the opening and closing action of door in use, it can be directly judged whether hinge body can make door open and close smoothly, auxiliary device is to buffer the impact force generated in the process of swinging, make door swing in a relatively uniform speed, stable state, provide more reliable data support for judging whether hinge body quality is qualified.
