Based on ISO5393 standard, Danikor Intelligent Tightening Tool adopts self-developed high-precision algorithm, which makes its performance more stable and durable, and provides a variety of tightening strategies to adapt to the increasingly complex working conditions of new energy vehicle assembly. By monitoring the torque or angle of each step in the tightening process, abnormal tightening conditions such as floating lock and sliding tooth can be found in time. It has the functions of data acquisition, uploading and storage, which is convenient for timely analysis and optimization of tightening process. In addition, tightening data can be uploaded to MES system in real time to achieve traceability of tightening results. It provides a cost-effective intelligent tightening solution for the assembly of new energy vehicles, and helps the digital intelligent assembly of new energy vehicles to enter the "fast lane".
