Publication number: 20240035909Abstract: Method to check the correct functioning of a tightening tool, such as an industrial screwdriver, placed on a test bench. Said bench includes a plurality of hydraulic brakes (F1-Fn), to which the instrument is associated, suitably controlled by a hydraulic circuit. Each brake is equipped with measurement transducers (TR) capable of measuring the torque exerted and the angle of rotation on this brake, connected to an electronic driver card (SP), which also controls the hydraulic circuit. The bench also includes an electronic processing unit (U) which communicates with the card and which includes an adequate driving program memorized on it capable of regulating the braking capacity of the brakes through the hydraulic circuit according to a predetermined braking torque/angle of rotation curve of the brakes.Type: ApplicationFiled: December 2, 2021Publication date: February 1, 2024Applicant: ATLAS COPCO INDUSTRIAL TECHNIQUE ABInventors: MASSIMILIANO CATTANEO, GIANMARIA CELICO FADINI, ROBERTO GEROSA, DANIELE AZZONE

Patent number: 10935450Abstract: System for verifying the proper functioning of industrial screwdrivers placed on a test bench that has a plurality of hydraulic brakes (F), with which the screwdriver is associated, suitably controlled by a hydraulic circuit comprising one pump (P), which withdraws the fluid from a reservoir (T) and provides it to a pressure regulating valve (VP), which in turn provides it to the brakes. Each brake is provided with measuring transducers (TR), connected to an electronic driver board (SP). A computer (U) communicates with such card and comprises a suitable driving program stored thereon, the driving program, once an operator has selected the brake to be used for testing the screwdriver, being able to progressively increase the braking capacity of the brakes by adjusting the pressure, until reaching a complete stop of the electronic screwdriver.Type: GrantFiled: July 19, 2017Date of Patent: March 2, 2021Assignee: ATLAS COPCO INDUSTRIAL TECHNIQUE ABInventors: Massimiliano Cattaneo, Gianmaria Celico Fadini
