Deep analysis of the control system for the bolt tightening machine of Dalian 4-axis differential assembly
In the Dalian 4-axis differential assembly bolt tightening machine, the control system is like the "brain" of the equipment, playing a decisive role in tightening accuracy, production efficiency, and safety. It achieves precise control of the tightening process through precise software and hardware collaboration.
The hardware architecture of the control system is centered around an industrial grade PLC (Programmable Logic Controller), paired with high-performance servo drivers and sensor modules. PLC is responsible for receiving and processing various signals, and sending instructions to the servo driver according to the preset program to drive the precise action of the tightening shaft; High precision torque sensors and angle encoders collect real-time tightening data, feedback torque values and angle information to PLC, form closed-loop control, and ensure the accuracy of the tightening process. For example, when encountering resistance changes caused by bolt thread deviation or material differences, the system can quickly adjust torque output to avoid over tightening or under tightening.
Software functionality is the soul of a control system. Operators can set tightening parameters such as target torque, angle range, tightening sequence, etc. through the human-machine interface (HMI). The system supports saving multiple sets of parameters, making it easy to switch production tasks for different types of differentials. At the same time, the software has data statistics and analysis functions, which can automatically record the time and torque curve of each tightening, generate production reports, and facilitate quality traceability and process optimization. In addition, the software also integrates a fault diagnosis module, which can quickly locate the problem point and issue an alarm when abnormal signals are detected, such as sensor faults or torque deviations, guiding maintenance personnel to handle them in a timely manner.

The communication module endows the control system with the ability to "interconnect". Through communication protocols such as Ethernet and CAN bus, the tightening machine can exchange data with the workshop MES system and PLC control platform, upload production data in real time, receive production task instructions, and help achieve intelligent management and scheduling of the production line.
The control system of the 4-axis differential assembly bolt tightening machine, with its hardware configuration, intelligent software algorithms, and efficient communication capabilities, provides reliable and accurate technical support for differential assembly, promoting automotive manufacturing towards automation and digitization.
