Abstract
The application belongs to the technical field of ferromagnetic part testing, and discloses a magnetic performance testing device and testing method for magnetic materials. The testing device comprises a testing table, which is provided with a plurality of testing holes and a sample placing hole. A proximity sensor and a testing block are arranged in the testing hole, and the testing block is an iron core block. A pressure sensor is arranged above the testing block. The testing device further comprises an analysis system, and data received by the proximity sensor and the pressure sensor is transmitted to the analysis system. The testing method comprises the following steps: placing a sample block to be tested into a limiting sleeve, placing a moving part on a fixed part, aligning the sample placing hole with the testing hole, transmitting data received by the proximity sensor and the pressure sensor to the analysis system, and completing the testing of the magnetic force intensity of the sample block to be tested; rotating the moving part to make the sample placing hole communicate with the testing hole, and judging the magnetic pole of the sample block by the approach or departure of the sample block and a standard magnetic part. The application can complete the testing of the magnetic performance by the attraction between the sample to be tested and the testing block.
