Sažetak
The focus of this work is aimed on enhancing the present design solution of the measurement line that would provide more accurate results and increase the speed and reliability of the recalibrating process of torque tools. Tools considered here are operated by hand, thus subjected to the performance (skill, physical strength and knowledge) of the operator. Since the pulling speed and the force are difficult to maintain or repeat by manual handling results are scattered and differ from expected values. In order to improve this process as well as fulfil compliance with international norms electrically controlled actuating device is considered. Among several analyzed solutions one with gearbox and trapezoidal spindle is chosen to be manufactured and implemented. Device testing has shown enhanced repeatability of the measurement, ease of operation and suitability for implementing automation features.
