What is Dalian tightening machine? Detailed explanation of working principle, classification and core technology

Dalian tightening machine is a core equipment for industrial automation assembly, mainly used for precise locking operations of various bolts, nuts, and screws. It is widely used in industries such as new energy, automotive parts, home appliances, 3C electronics, and precision machinery. Compared to traditional manual electric batch locking, the tightening machine has higher precision and stronger consistency, which can completely solve the assembly problems of missing screws, floating locks, slipping teeth, and uneven torque. It is a standard equipment for modern intelligent production lines.

The core working principle of the tightening machine is torque closed-loop control. The device collects real-time locking process data through servo motors and torque sensors, and accurately outputs the set torque and speed. When doing homework, first align at low speed and feed quickly. After contacting the workpiece, automatically switch to precision tightening mode, monitor torque, angle, and speed changes in real time, and immediately stop and lock when the preset standards are reached. At the same time, automatically determine the tightening result, distinguish between qualified, missed, virtual, and over tightened states, and achieve standardized locking.

According to structure and function, Dalian tightening machines are mainly divided into two categories. Single axis servo tightening machine is flexible and portable, suitable for assembly of multiple categories and small batches of products, easy to debug, and has strong universality; The multi axis automatic tightening machine can achieve synchronous locking of multiple screws, with extremely high efficiency, and is suitable for large-scale fixed workstation operations such as shells and assemblies. In addition, it can be divided into fixed, handheld, and gantry tightening models to meet the needs of different production line layouts.

The core technology of the tightening machine focuses on high-precision control and data traceability. The equipment is equipped with high-precision torque sensing technology, with a torque repetition accuracy of ± 3%, ensuring uniform locking force for each screw. Relying on intelligent algorithms, it can adapt to different screw resistances and avoid problems such as slipping teeth and locking damaged workpieces. Simultaneously supporting full process data recording and uploading to MES system, achieving real-time storage, query and traceability of tightening data, meeting the strict production standards of industrial quality control, automotive and new energy industries.

In summary, the tightening machine, with its advantages of high precision, high efficiency, and traceability, completely replaces manual extensive assembly, effectively improves product assembly stability, reduces defect rates, and helps enterprises achieve automation and intelligent upgrading of assembly processes.
