The ECR Angle Fixture Nut Runner, from AMT (ALfing Montagetechnik), is a powerful solution designed for automated, high-precision nut tightening in confined workspaces and at awkward angles.

Conquer Confined Spaces and Awkward Angles:

  • Angled Design: The nut runner boasts an angled output shaft, allowing for effortless access and secure fastening of nuts positioned at non-perpendicular angles or in tight areas.
  • Fixture-Mounted Precision: This nut runner integrates seamlessly into your dedicated fixture, ensuring consistent and accurate results for a specific fastening application.

Experience AMT’s Renowned Performance:

  • Fast Cycle Times: The ECR series excels in rapid operation, boosting your production output significantly.
  • Exceptional Precision: Integrated torque and angle sensors guarantee consistent and reliable fastening, minimizing errors and rework.
  • Durable Construction: Built to last, the ECR Angle Fixture Nut Runner delivers long-lasting performance within demanding industrial environments.

Benefits of Utilizing the ECR Angle Fixture Nut Runner:

  • Effortless Integration: Seamlessly integrate the nut runner into your existing assembly line or robotic system for a streamlined workflow.
  • Enhanced Efficiency: Fast cycle times and reduced rework contribute to significant productivity gains.
  • Improved Quality Control: Precision fastening minimizes errors and ensures consistent results, enhancing product quality.
  • Ergonomic Advantages: The angled design improves ergonomics for human operators or reduces stress on robots during automated fastening in tight spaces.

Ideal Applications for the ECR Angle Fixture Nut Runner:

  • Automotive assembly lines (engine compartments, chassis)
  • Aerospace component manufacturing (complex structures)
  • Electronics manufacturing (circuit board assembly)
  • Appliance assembly (tight internal components)
  • Any application requiring precise nut fastening at angles or in confined spaces

Powerful – Efficient – Intelligent

Short assembly times and the high availability of nut runners are indispensable in automatic assembly stations. That is why we only use maintenance-free and highly dynamic EC motors as drives.

Cost Reduction Through Modular Design

Fixture nut runners from AMT have modular constructions, which means individual components like the drive type or torque sensors can be combined as needed. The modular construction additionally reduces your costs for spare parts and repairs.

Integrated Data Chip

Our ECR Angle Fixture Nut Runner are also “intelligent”. They automatically transfer their specific data to our spindle controller and notify the user when preventive maintenance is necessary.

ACTION TORQUE SENSOR FOR THE HIGHEST PRECISION

Fixture nut runners from AMT stand for the highest precision during the assembly process. That is why we prefer to use an action torque sensor to record the torque in the control circuit. Here the torque is measured as close as possible to the hex of the bolt, this means directly on the drive shaft. Any changes in effectiveness in the angle or offset drives due to wear therefore do not influence the tightening torque. If the tightening torque is achieved, the assembly process will be executed securely independent of the mechanical condition of the drive.

Advanced Process Safety Through Redundancy

The VDI directive 2862 recommends the use of redundant torque sensors for category A fastening joints (direct or indirect injury and death hazard). AMT fixture nut runners record the values with these designs as follows:

Control Circuit:

  • Torque measurement through an action torque sensor
  • Angle recording through an angle sensor

Control Circuit

  • Torque measurement through a reaction torque sensor
  • Angle recording through resolver

The transmission and processing of the measurements by the control circuit is carried out independently until the final comparison. A deviation in the compared values leads to an NIO statement.

ECR Angle Fixture Nut Runner  Integrated Maintenance Management

Even the most reliable of nut runners are subject to natural wear. To make sure that this wear does not lead to a sudden failure of the tool, the tools from AMT automatically notify the user when preventive maintenance is required. A maintenance cycle counter integrated into the nut runner with a load-dependent evaluation ensures that necessary maintenance is reported on time. This increases the availability of the nut runner through a wear-dependent replacement of components.
