Products & services
Automated joining of bearings and shafts is essential for precise, reliable and efficient production. Conventional processes reach their limits due to tolerances, material properties and high manual effort.
Feinwerktechnik Otto Harrandt GmbH developed an innovative assembly station that structures and efficiently designs the entire joining process. It utilizes high-precision force-displacement monitoring, which enables detailed control of the joining process and immediately detects any deviations. The team solved a particular challenge: the double joining of both bearing shells using a clever mechanical layout and design. The developed assembly station not only offers advantages for the automotive industry, but can also be adapted to other industries and components. Thanks to its flexible control and precise force-displacement monitoring, the technology is suitable for applications in the aerospace, mechanical engineering, defense, and agricultural sectors. Components such as bearings, shafts, and other precision components can be assembled with the highest precision, increasing quality and efficiency across all industries. The introduction of the Harrandt machine led to a sustainable optimization of the assembly process. The precise control and monitoring of each individual joining process significantly increased process reliability, significantly reducing errors and scrap. This not only ensures consistently high quality of the assembled components, but also minimizes costly rework and material waste. Thanks to the integrated force-displacement monitoring, every production step can be precisely documented and evaluated. This creates complete transparency throughout the entire assembly process and enables predictive maintenance, thereby reducing unplanned downtime. This successful collaboration underscores the innovative strength of Feinwerktechnik Otto Harrandt GmbH and demonstrates how customized automation solutions contribute to increased efficiency in industrial production.
Precise torque control ensures stable connections, prevents material fatigue and mechanical failure. Automated sensor technology ensures consistent quality of the screw connections.
Präzise Drehmomentkontrolle für maximale Stabilität: Unsere Schraubsysteme gewährleisten durch präzise Drehmomentsteuerung die notwendige Klemmkraft, um eine sichere und stabile Verbindung zu garantieren. Vermeidung von Materialermüdung und mechanischem Versagen: Durch die exakte Kontrolle des Anziehprozesses werden Überbeanspruchungen vermieden, die zu Materialermüdung oder mechanischem Versagen führen könnten. Automatisierte Qualitätssicherung für gleichbleibende Schraubverbindungen: Unsere Systeme integrieren fortschrittliche Sensorik und Überwachungstechnologien, um eine konsistente Qualität der Schraubverbindungen sicherzustellen.
The assembly line developed by Harrandt enables the flexible assembly of up to 8 motor variants without set-up work. With its high precision, efficient cycle times and innovative test procedures, it stands for automation, quality and process reliability.
For the assembly line, which was designed, built, and successfully commissioned by Feinwerktechnik Otto Harrandt GmbH, we relied on components from leading manufacturers. The heart of the assembly line are the 30 workpiece carriers, on which a total of five different high-performance engines can be processed in one cycle time. The Harrandt assembly line is also capable of handling up to eight different engine variants without additional setup procedures or workpiece carrier changes. The servo axes offer highly dynamic motion sequences and guarantee precise positioning. The transfer system ensures a smooth material flow, while door safety switches and sensors guarantee maximum safety and precision. The safety components – fences and protective covers – and the pressure-sensitive mats provide the necessary safety precautions to meet the requirements of a modern production environment. A DMC scanner is used for optical quality control, enabling complete traceability and also checking the correct combination of piston and connecting rod. The entire system is controlled by the proven Siemens PLC, which, in conjunction with the high-precision gripper and all other components, ensures smooth automation. The system is rounded off by innovative lubrication systems.
Our robot-supported assembly lines offer sensor-monitored real-time error detection, precise joining processes for sensitive components and flexible integration of new components for maximum process reliability and efficiency.
Our assembly lines are equipped with advanced sensor systems that detect errors in real time, significantly increasing process reliability. This ensures consistently high quality and reduces scrap. Particularly sensitive components are joined gently through precise control of force, position, and speed to avoid mechanical overload and damage. Thanks to our modular, robot-assisted systems, new components can be quickly and flexibly integrated into the assembly process, enabling future-proof production. By using intelligent robotics solutions, we implement precise and fast pick-and-place processes that ensure optimal material feeding and increased production output. Our robot systems also integrate automated spot taping applications to reliably secure components, increase process reliability, and minimize manual effort. With our many years of experience in the development and implementation of automated assembly lines, we offer customized solutions for demanding manufacturing processes. From design and the integration of intelligent robotics to quality assurance, we focus on the highest levels of precision, efficiency, and process reliability to provide our customers with innovative and high-performance automation solutions.
