Abstract: Combined with the factory testing requirements of the self-adjusting thread insert of automobile brake clamp,inspection platform is designed to inspect the high pressure gas tightness of self-adjusting thread insert,micro leakage detection of self-adjusting thread insert by using the method of internal pressure differential method,and using control mode of combinating with PLC and MCGS,completed the motion process control,data acquisition and processing,automatic analysis and display of test results.The test results show that the inspection platform can accurately detect the sealing performance and pressure resistance of the self-adjusting thread insert,and the detection efficiency is high.

Key words: the self-adjusting thread insert, gas tightness, MCGS industrial control configuration software , Programmable Logic Controller(PLC)
