AI Technical Summary
Existing fixtures that can quickly inspect metal structural components cannot simultaneously inspect multiple springs of varying lengths.
Design a multi-station switching testing device for metal structural components. The device uses a motor to drive a disc on a transmission shaft to rotate. Combined with independently liftable pallets and pressure plates, it can apply or release pressure on multiple springs of different lengths. The device uses a hydraulic cylinder to lift the pallets and pressure plates to perform fatigue testing on springs of different lengths.
It enables simultaneous fatigue testing of multiple springs of different lengths, improving testing efficiency. During the testing process, it can automatically identify and replace fatigued springs, maintaining testing continuity.
