What is the difference between Dalian servo tightening machine and ordinary tightening machine, and how to choose assembly selection

In the field of industrial assembly, Dalian servo tightening machine and ordinary tightening machine are mainstream locking devices, and many enterprises easily confuse the two when renovating production lines and purchasing equipment. The two have significant differences in control accuracy, locking stability, intelligent functions, and applicable working conditions. Accurately distinguishing differences and selecting according to needs can balance assembly quality and production costs.

The fundamental difference lies in the differences in core control principles. Ordinary tightening machines are mostly driven by pneumatic and fixed speed motors, relying on mechanical limit and clutch stop to control torque, without real-time data monitoring. The equipment has large torque errors and poor repeatability, making it prone to floating locks, overtightening, and slipping during operation. It is difficult to accurately control the locking force of each screw, and can only meet the basic locking requirements.

The Dalian servo tightening machine is equipped with servo motors and high-precision torque sensors, using a closed-loop control system to collect real-time torque, angle, and speed data, and dynamically adjust the tightening force and speed. The torque repetition accuracy can reach ± 3%, and the locking process is controllable and error correcting. It can automatically identify poor states such as missed twisting, virtual twisting, and slipping teeth, completely solving the assembly deviation problem between manual and ordinary equipment.

There is a significant gap between the two in terms of functionality and practicality. The ordinary tightening machine has a simple structure, low price, and easy maintenance, but lacks data storage and traceability functions, and is suitable for low precision requirements and large-scale assembly of ordinary workpieces. The servo tightening machine supports real-time data storage and integration with MES system, with intelligent error prevention and adaptive pressure and speed regulation functions, suitable for precision and high standard assembly scenarios.

Assembly selection can directly refer to the working condition requirements. Ordinary household appliances, general hardware and other ordinary assemblies with low precision requirements and no need for quality control traceability should prioritize the use of ordinary tightening machines to reduce equipment investment costs. Industries such as automotive parts, new energy, and precision 3C electronics that have strict requirements for torque accuracy, assembly consistency, and data traceability must use servo tightening machines to ensure product assembly stability and yield.
