In the assembly of critical components such as automotive engines, cylinders, and new energy drive motors, the requirements for air tightness and residual torque during tightening operations are extremely strict. These areas typically involve the fastening of multiple bolts, and the traditional sequential tightening method can easily lead to elastic interactions between bolts, resulting in a decrease in preload and even inconsistent torque values. To address this challenge, the multi-axis synchronous tightening strategy has emerged.

Core Principle of Synchronous Tightening Strategy

The core of the synchronous tightening strategy lies in the synchronous control of tightening program nodes for multiple bolts, achieving synchronized waiting and stress relief during the tightening process. Specifically, during tightening, multiple bolts reach a preset torque or angle node simultaneously and pause at that node, waiting for the other bolts to reach their respective nodes before continuing. This synchronous mechanism effectively reduces torque decay and avoids torque inconsistency caused by different tightening sequences.

Application Advantages of Synchronous Tightening Strategy

In key areas such as automotive engines, cylinders, and new energy drive motors, the synchronous tightening strategy offers significant advantages. For example, in the assembly of engine blocks and cylinder heads, synchronous tightening ensures that all bolts are evenly loaded, preventing sealing issues or structural damage due to localized stress concentration. In the assembly of new energy drive motors, the synchronous tightening strategy also ensures the connection quality of critical components like motor housings, enhancing overall reliability and durability.

Application of Danikor Tightening Guns in Synchronous Tightening

Danikor tightening guns, with their high-precision control algorithms and multiple tightening strategies, are well-suited for synchronous tightening applications. The torque control accuracy of their sensor-based tightening guns can reach ±1.67%, with high angle control precision, meeting the high-precision assembly requirements of automotive engines and new energy drive motors. Additionally, Danikor tightening guns feature full-process data traceability, enabling real-time upload of tightening data to MES systems for complete production monitoring and quality traceability.

In practical applications, Danikor tightening guns ensure that multiple tightening spindles remain synchronized throughout the tightening process through multi-axis synchronous control functionality. For instance, in multi-axis tightening machines, Danikor tightening guns can achieve synchronous cap recognition, pre-tightening, and final tightening across multiple spindles. This synchronous control not only improves tightening quality but also significantly enhances production efficiency.

The synchronous tightening strategy effectively resolves the issue of torque inconsistency found in traditional tightening methods through multi-axis synchronous control, significantly improving the assembly quality of critical components such as automotive engines, cylinders, and new energy drive motors. With their high-precision control and diverse tightening strategies, Danikor tightening guns provide reliable tool support for synchronous tightening strategies, contributing to the high-quality development of the automotive manufacturing and new energy industries.
