What is the working principle of Dalian tightening machine?

As the core equipment of automated assembly, the working principle of industrial tightening machine revolves around "precise control of tightening process". Through the coordination of mechanical structure and intelligent system, it achieves efficient locking of bolts, nuts and other fasteners.

Its core components include four modules: power system, transmission mechanism, torque sensor, and control system. The power system usually uses servo motors or pneumatic motors to provide stable power for tightening actions: servo motors are suitable for high-precision scenarios and can accurately control the speed and output torque through current signals; Pneumatic motors are driven by compressed air and are suitable for operations in high-frequency and harsh environments.

The transmission mechanism is responsible for converting power into tightening action. Common gearboxes and planetary reducers can reduce the motor speed to the appropriate tightening speed while amplifying torque output. As a component that directly contacts fasteners, the batch head can adapt to various connecting parts such as bolts and screws by replacing them with different specifications, ensuring efficient transmission of power to the locking point.

The torque sensor is the key to ensuring accuracy, as it can monitor the torque value in real-time during the tightening process and convert the data into electrical signals for feedback to the control system. When the torque reaches the preset threshold, the sensor triggers a shutdown command to avoid over tightening or under tightening - this closed-loop feedback mechanism allows the tightening accuracy to be controlled within ± 3%, far higher than the error range of manual operation.

The control system is equivalent to the "brain" of the tightening machine. The operator sets parameters such as torque and speed through the touch screen. The system's built-in algorithm automatically optimizes the tightening curve based on the material and specifications of the fasteners (such as low-speed alignment, high-speed tightening, and pressure verification). Some high-end models are also equipped with visual recognition or force feedback modules, which can automatically correct bolt deviation and further improve assembly reliability.

Essentially, the Dalian tightening machine utilizes a closed-loop logic of "power output process monitoring intelligent control" to transform the empirical operation of manual tightening into standardized and data-driven industrial actions. This is also the core reason why it is indispensable in precision manufacturing fields such as automobiles and aerospace.
