This paper presents a mechatronic device that finely corrects the fastening position of test standards and applies it to the automated testing procedure of metering current transformer.In the automated test, there is a certain deviation between the measurement transformer size and the standard size, and the actual small deviation will affect the contact area of the secondary crimping, which will affect the consistency and accuracy of the test results. In this paper,we design a corrective pushing component and a positioning clamp assembly structure, and used an adaptive control algorithm to effectively fix and correct the position of the tested transformer. The actual results show that the test position of the tested product is effectively calibrated, and the accuracy and stability of the automated test are greatly improved.
