Introduction and Application of Synchronous Tightening Strategy

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 is prone to elastic interactions between bolts, leading to a decrease in preload and even inconsistent torque. To solve this problem, the multi-axis synchronous tightening strategy has emerged.

Core Principle of Synchronous Tightening Strategy

The core of the synchronous tightening strategy lies in achieving synchronous waiting and stress elimination during the tightening process by synchronously controlling the tightening program nodes of multiple bolts. Specifically, during the tightening process, multiple bolts will simultaneously reach the preset torque or angle nodes, and pause at these nodes, waiting for other bolts to reach the corresponding nodes before continuing to tighten. This synchronous mechanism can effectively reduce torque decay and avoid inconsistent torque caused by different tightening sequences.

Application Advantages of Synchronous Tightening Strategy

In key components such as automotive engines, cylinders, and new energy drive motors, the synchronous tightening strategy has significant advantages. For example, in the assembly of engine blocks and cylinder heads, synchronous tightening can ensure that all bolts are evenly stressed, avoiding sealing problems or structural damage caused by local stress concentration. In the assembly of new energy drive motors, the synchronous tightening strategy can also ensure the connection quality of key components such as the motor housing, improving overall reliability and durability.

Application of Danikor Tightening Gun in Synchronous Tightening

With its high-precision control algorithms and various tightening strategies, Danikor tightening guns can be well adapted to the synchronous tightening strategy. The torque control accuracy of its sensor-type tightening gun can reach ±1.67%, with high angle control accuracy, meeting the high-precision assembly requirements of automotive engines, new energy drive motors, etc. In addition, Danikor tightening guns also have full-process data traceability function, capable of real-time uploading of tightening data to the MES system, achieving full-process monitoring and quality traceability of the production process.

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

The synchronous tightening strategy effectively solves the problem of inconsistent torque 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 its high-precision control and various tightening strategies, Danikor tightening guns provide reliable tool support for the synchronous tightening strategy, contributing to the high-quality development of the automotive manufacturing and new energy industries.
