AI Technical Summary
Technical Problem
Existing technologies make it difficult to effectively measure the impact resistance of C-shaped retaining rings.
Method used
A testing device was designed, comprising a connecting rod, an electromagnet mechanism, an impact hammer, a sensor, and an impact tip. The impact action of the impact hammer is controlled by energizing and de-energizing the electromagnet mechanism, and the impact resistance of the C-shaped retaining ring is measured by the sensor.
Benefits of technology
It enables automated measurement of the impact resistance of C-shaped retaining rings, allows for easy adjustment of the impact hammer height to suit different testing requirements, and displays the measurement results on the reading meter.
