Screw data and screw data management
Screw data in general
Screw data and screw data management represent an extremely complex field of knowledge that goes far beyond the mere "tightening of bolts". Rather, technical terms such as tightening torque, torque, angle of rotation, preload force, friction, lubrication, screw locking, thread diameter or even thread depth play a special role? These terms are familiar to you and do not present you with any challenges? Then you are undoubtedly a specialist. Just like ATON, because screw data management is the daily business of ATON GmbH.
Quality and safety for your production
Screwdriving technology occupies a special position in automotive manufacturing, as even in an average mid-range vehicle several hundred safety-critical screwdriving joints have to be made. The number of non-safety-critical bolted connections even runs into the thousands. These bolted joints or the corresponding screwdriving processes must be standardised in automotive production in terms of both quantity and quality and defined in reproducible processes.
Let's first look at the safety-critical screw connections in automotive manufacturing, such as axles, engines, gearboxes, brakes, clutches, wheels, doors, airbags, seats, belts as well as the entire cockpit.
In addition to the design, the design-related dimensions, the materials used and the tightening forces are decisive for a successful bolted joint.
The torques that occur range from a few Newton metres for small brackets and hinges to several hundred Newton metres for engine, gearbox and chassis connections.
In order to ensure that the requirements for quality and safety rightly demanded by customers and supervisory authorities are met in a standardised manner, not only perfectly working nutrunner tools are required, but also perfectly working control systems that receive the production commands from the higher-level factory control system, prioritise them, control the nutrunner tools and receive the nutrunner results back from them after the nutrunner process has been completed.
The quality-relevant screwdriving results are documented accordingly at the request of quality assurance and stored in an audit-proof manner so that individual quality data of the produced vehicles can still be accessed on this screwdriving data even after many years.
