Abstract
The invention relates to the technical field of automobile automation test, specifically to a precise magnetic flux testing mechanism. The precise magnetic flux testing mechanism comprises a test platform for placing a measured object, a test assembly for testing the magnetic flux of the measured object, and a laser distance sensor for testing the accurate distance between a magnet and the measured object. The laser distance sensor can accurately measure and test the distance between the magnet and the measured object, and the real-time distance is fed back to a lifting motor through communication to accurately control the lifting speed and lifting height of the lifting motor. The test rate is accelerated, and the test accuracy is improved. The test steps are simplified, and the requirements on test workers are lowered. A vertical slide rail allows a tester to ascend and descend strictly following the vertical direction when driven by the lifting motor, so that the test data are more accurate.
