- Electronics manufacturing (unevenly spaced components)
- Appliance assembly (internal components with limited access)
- Any application requiring precise nut fastening at angles or in confined spaces
PDFPowerful – 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 Offset 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
ECR Offset Fixture Nut Runner 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 nutrunners 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.
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.
