Analysis of core components of Dalian servo press fitting machine: how motors and sensors work together

The precise pressing ability of Dalian servo pressing machine relies on the efficient coordination between servo motors and various sensors. As the core of power output and data sensing terminal, the combination of the two forms a closed-loop link of "instruction execution feedback correction", which is the key to achieving high-precision and high stability press fit of the equipment. Starting from the functions of the components, analyze the inherent logic of their collaborative work.

The servo motor is the "power heart" of the servo press fitting machine, responsible for the core responsibilities of power output and precise driving. It receives pulse commands from the control system through a servo drive, which can accurately adjust the speed, torque, and steering, and then drive the ball screw to convert rotational motion into linear pressing action. Compared to traditional motors, servo motors have the advantages of fast response speed (in milliseconds), wide speed range, and the ability to switch power output modes according to the requirements of the pressing stage, providing a flexible power foundation for collaborative work.

Sensors are the "sensory nerves" of devices, mainly including pressure sensors and displacement sensors, responsible for real-time collection of key data during the pressing process. The pressure sensor is installed at the end of the pressure head or screw to accurately capture the dynamic changes of the pressing force; The displacement sensor monitors the stroke position of the pressure head in real time, and the two synchronously transmit the collected pressure and displacement data to the control system, providing data support for collaborative regulation.

The core of the collaboration between the two lies in "dynamic feedback adjustment": after the control system preset the pressing parameters, the servo motor starts and outputs power according to the instructions; During the pressing process, the sensor continuously uploads real-time data, and the system compares it with the preset parameters. If there is a deviation (such as excessive pressure or displacement offset), it immediately sends a correction command to the servo drive; The servo motor quickly responds and adjusts the speed and torque until the pressing parameters meet the standards. This collaborative mode of "power output data perception precision correction" ensures the precision and stability of the servo press fitting machine.
