Abstract: A tool is equipped with a torque sensor, suited for a tightening task of a fastening component of a device such as a fluid control system that requires a large number of fastening components for assembly and has a narrow space for access to the fastening components, and capable of automatically detecting a tightening torque. The tool includes a torque sensor capable of detecting a tightening torque for tightening a fastening component acting on a bit. The torque sensor initiates measurement of the tightening torque when the tightening torque detected exceeds a set threshold value, completes measurement when the tightening torque detected falls below the set threshold value and a set time elapses, and outputs torque-related data formed on the basis of measurement data from measurement initiation to measurement completion and including a measurement time. The torque-related data includes a peak value of the measurement data.

Abstract: The electric screwdriver apparatus control method is executed by an electric screwdriver apparatus. A processing module of the electric screwdriver apparatus loads a configuration data, and the processing module controls a motor module to accelerate a rotational speed to a target rotational speed. When a revolution number exceeds a first revolution number, the processing module controls the motor module to decelerate to a first rotational speed. When a torque value exceeds a first torque value, the processing module determines whether a fastening process of a screw ends with a hard stop or a soft stop according to the configuration data. If the fastening process ends with the hard stop, then the screw is additionally tightened for a hard stop angle, vice versa. The processing module tightens the screw according to the configuration data, the torque value and a rotational speed value, improving the process of fastening the screw.

Abstract: A method for measuring an axial-force of a bolt fastened to a component to be fastened, includes temporarily fastening the bolt to the component to be fastened with a temporarily-tightening torque, the temporarily-tightening torque being a torque which is determined in advance and by which a depression is formed on a head of the bolt, measuring a first axial force of the temporarily-fastened bolt, regularly fastening the bolt to the component to be fastened with a regularly-tightening torque, the regularly-tightening torque being torque which is determined in advance and larger than the temporarily-tightening torque, measuring a second axial force of the regularly-fastened bolt, and measuring an estimated axial force of the regularly-fastened bolt by using the torque with which the bolt is temporarily fastened, the torque with which the bolt is regularly fastened, and a difference between the first and second axial forces.

Abstract: A system for verifying proper functioning of industrial screwdrivers placed on a test bench is provided. The bench includes a plurality of hydraulic brakes, with which the screwdriver is associated, controlled by a hydraulic circuit including a pump, which withdraws the fluid from a reservoir and provides it to a pressure regulating valve, which in turn provides it to the brakes. Each brake is provided with measuring transducers connected to an electronic driver board, which also controls the regulating valve. A hydraulic distributor is present between the brakes and the regulating valve, the hydraulic distributor including solenoid valves able to select, operate and control the hydraulic pressure of each brake to which it is selectively connected. A computer communicates with the board and includes a driving program stored thereon capable of progressively increasing the braking capacity of the brakes according to a preset braking torque/brake rotation angle curve.

Abstract: A test device (10) for testing screwing devices, comprising a shaft (14) with an end (15) for connection to a screwing device and an opposite end (16) for connection to a joint to be screwed. The device (10) further comprises a first transducer (18) for detecting the rotation angle of the shaft (14) and a second transducer (19) for detecting the torque transmitted by the shaft (14) between the two ends (15, 16). The device (10) further comprises a control unit (20), an NFC communication module (31), a memory (30), and means (24, 31) for communication with the outside. The control unit stores in the memory (30) an identification code received from the NFC communication module (31) and associates it in the memory (30) with test data obtained from the first and second transducers (18, 19). Then the communication means (24, 31) send to the outside data obtained from the contents of the memory (30). A method for testing and managing the tests and a system which comprises in addition to the test device (10) also at least one NFC tag (33) are also described.
