The press fitting process in industrial motor production requires high assembly precision. The interference fit of bearings, end caps, rotors and shafts needs stable and controllable force. Manual hammering or simple pressing cannot guarantee consistency and may damage parts. Taizhou Yufeng Intelligent Equipment Co., Ltd. plans production lines for motor companies and configures specialized press fitting machines to standardize key pressing processes.
Design points of the specialized press fitting machine
The specialized press fitting machine is designed with dedicated tooling and pressing heads. It uses servo or hydraulic drive, and the pressing force, speed and hold time can be set and recorded. The machine is equipped with force-displacement monitoring to detect the pressing curve in real time and alarm on abnormality. Different motor models switch through quick-change pressing heads and locating tooling to shorten changeover time.
Station division of the motor line
The motor production line is divided into stator assembly, winding treatment, rotor assembly, bearing pressing, integration, testing and packing stations. The bearing pressing station uses a specialized press fitting machine to control pressing force and position accuracy. The end cap pressing uses locating fixtures to ensure concentricity. The integration station completes the combination of stator, rotor and end caps, then performs rotation testing and electrical testing.
Press fitting quality control
Press fitting quality is controlled through force and displacement data. The system records the pressing curve of every motor and sets upper and lower limits for judgment. When an abnormality occurs, the line stops automatically with a prompt to prevent non-conforming products from flowing downstream. Press data is bound to the product number for traceability and statistical analysis.
Testing and factory verification
Before shipment, motors undergo insulation resistance, winding resistance, no-load current, withstand voltage and vibration testing. Test equipment sets parameters according to standards and records results automatically. For motors with load requirements, a load test bench verifies performance. Qualified products enter the packing stage.
Line planning and investment
Press fitting and test equipment are the core investment of a motor line. When planning, select equipment according to motor specifications, output and precision requirements, and optimize the layout with existing equipment. We provide equipment configuration, station design and cycle plans to help companies improve capacity and consistency within a reasonable investment.
