AI Technical Summary

Technical Problem

The repeated testing of the internal cord angle and cord thickness in the existing technology of air spring airbags results in low testing efficiency and poor consistency in the air spring airbag expansion diameter test.

Method used

An auxiliary testing device is provided, including an inflation component, a lifting component, a first robotic arm, and a second robotic arm. The device automatically assembles spring clamps and uses an inflation and pressure-holding device to inflate the airbag to a preset state, and directly measures the inflated diameter.

Benefits of technology

This improves the efficiency and consistency of testing the inflation diameter of air spring bladders, reduces dependence on cord angle and thickness, and achieves an automated and precise testing process.

Abstract

The application provides an auxiliary testing device for assisting in testing the inflation diameter of an air spring air bag, which can completely replace manual assembly of spring clamps to assemble and fasten the air spring air bag to the inflation joint by only using a first mechanical hand to clamp a first spring clamp and a second mechanical hand to clamp a second spring clamp to assemble and fasten two ends of the air spring air bag to the first air joint and the second inflation joint respectively, and then inflating the air spring air bag through an inflation pressure maintaining device to make the air spring air bag adapt to inflation, so that the inflation diameter of the air spring air bag can be directly tested by using a measuring tool such as a caliper, the manual test of the inflation diameter of the air spring air bag by using the measuring tool is assisted, the degree of automation is high, the air bag with the inflation diameter meeting the standard can be directly tested without repeatedly testing the cord angle and the cord thickness inside the air spring air bag, and the test efficiency of the inflation diameter of the air spring air bag is improved.
