In the assembly of critical components such as automotive engines, cylinders, and new energy electric drive motors, the requirements for the airtightness and residual torque of tightening operations are extremely strict. These components often involve the fastening of multiple bolts, and the traditional method of tightening each bolt individually can easily lead to elastic interaction between bolts. This can cause a decrease in preload force and even result in inconsistent torque. To address this challenge, the multi-axis synchronous tightening strategy has been developed.

Core Principle of Synchronous Tightening Strategy

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

Application Advantages of Synchronous Tightening Strategy

In critical components such as automotive engines, cylinders, and new energy electric 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 caused by localized stress concentration. In the assembly of new energy electric drive motors, the synchronous tightening strategy also ensures the connection quality of key components such as the motor housing, enhancing overall reliability and durability.

Application of Danikor Tightening Systems in Synchronous Tightening

Danikor's tightening systems, with their high-precision control algorithms and multiple tightening strategies, can well adapt to the synchronous tightening strategy. The torque control accuracy of Danikor's sensor-based tightening guns can reach ±1.67%, and they have high angle control accuracy, meeting the high-precision assembly needs of automotive engines and new energy electric drive motors. In addition, Danikor's tightening systems are equipped with full-process data traceability functions, which can upload tightening data in real-time to the MES system, enabling full-process monitoring and quality traceability of the production process.

In practical applications, Danikor's tightening systems, with their multi-axis synchronous control function, can ensure that multiple tightening axes remain synchronized during the tightening process. For example, in the application of multi-axis tightening machines, Danikor's tightening systems can achieve synchronization of cap recognition, pre-tightening, and final tightening for multiple tightening axes. This synchronization not only improves tightening quality but also significantly increases production efficiency.

The synchronous tightening strategy, through multi-axis synchronous control, effectively solves the problem of inconsistent torque in traditional tightening methods and significantly improves the assembly quality of critical components such as automotive engines, cylinders, and new energy electric drive motors. Danikor's tightening guns, with their high-precision control and multiple tightening strategies, can provide reliable tool support for the synchronous tightening strategy, contributing to the high-quality development of the automotive manufacturing and new energy industries.
