Analysis of the working principle of high-precision Dalian tightening machine

As the core equipment of industrial locking, high-precision tightening machines rely on a closed-loop working system of "power drive torque sensing intelligent control" for their precision and stability. This system deeply integrates mechanical transmission, sensing technology, and intelligent control to achieve precise control of the entire bolt locking process, adapting to diverse locking needs from micro electronic components to heavy mechanical parts.

The power drive system is the "power heart" of Dalian tightening machine, mainly composed of servo motor and reduction mechanism. The servo motor provides stable power for tightening action with high-precision speed control capability; The reduction mechanism converts the high speed of the motor into low speed and high torque output that meets the locking requirements through a gear set, avoiding bolt slippage or loose locking due to high speed. For bolts of different specifications, the system can achieve stepless adjustment of torque output by adjusting the motor current frequency, and is suitable for multi specification bolt locking such as M1-M50.

The torque sensing and feedback system is the core to ensure "precise locking". The device is equipped with a high-precision torque sensor that can capture subtle changes in torque during the locking process in real time, with an accuracy of up to ± 0.5%. When the bolt is in contact with the workpiece and enters the tightening stage, the sensor synchronously transmits torque data to the central control system. The system dynamically adjusts the motor output power by comparing the preset torque value. For example, in car cylinder head locking, when the torque approaches the preset threshold, the system will gradually reduce the speed to avoid instantaneous torque overload and damage to the workpiece.

The intelligent control system of Dalian tightening machine undertakes the function of "brain decision-making", integrating PLC controller and human-computer interaction interface. After the operator preset parameters such as torque, speed, and tightening angle through the interface, the system will automatically plan the locking process. At the same time, the system has data recording and fault diagnosis functions, which can store the torque curve data of each lock, facilitating quality traceability; If abnormal torque or motor overload occurs, it will immediately trigger shutdown protection and alarm to ensure operational safety. It is precisely the working principle of multi system collaboration that enables high-precision tightening machines to achieve the unity of precision and reliability.
