摘要： An object is to provide a torque tool device which can positively identify which torque tool was used to tighten a bolt. Another object is to provide a torque tool device which can be provided with traceability from the torque tool to standards of torque.A torque wrench 1 transmits, after having tightened a bolt, a set of the manufacturer's serial number of the torque wrench 1 and tightening data such as a measured torque value to a processing terminal 20. The processing terminal 20 transmits the manufacturer's serial number and the tightening data to an externally connected device 30, so that the tightening data and data on the tightened bolt or the like are recorded by the manufacturer's serial number in the externally connected device. This makes it possible to identify the torque wrench 1 from the tightened bolt and maintain traceability.

摘要： An error of an axial force detection is reduced by tensioning a bolt with a tensioning device engaged with a part of the bolt, different from a shaft portion of the bolt. A tensioning device is configured to apply upward tension to a bolt fastened to a fastened member H, and fitted with a washer. A first male thread portion is formed on an outer circumferential surface of the washer. The tensioning device includes a connection member having a first female thread portion to be engaged with the first male thread portion, a tensioning mechanism for tensioning the connection member in a state where the first male thread portion is engaged with the first female thread portion, and a tension bearer which is disposed around an outer circumference of the connection member, and bears a reaction force applied from the fastened member H in tensioning performed by the tensioning mechanism.

摘要： A tightening tool such as a torque wrench is provided in which electric power can be fed to an electronic circuit with eliminating the need for a battery and achieving daily maintenance-free. In the tightening tool, when a tightening torque has reached a set torque value and a torque limiter is actuated, an electronic circuit unit that has obtained a detection signal outputted from a torque limiter actuation detection unit outputs a tightening completion signal. The tightening tool has a power generation unit for feeding electric power to the electronic circuit unit at least during the actuation of the torque limiter. The power generation unit performs photovoltaic power generation, electromagnetic induction power generation, power generation by conversion from mechanical energy into electrical energy, or temperature difference power generation.

摘要： An angle wrench has a simple structure and is capable of accurately measuring rotation angle. The angle wrench is used for tightening an object to be tightened by means of the rotation angle method, and includes a handle having a grip; a head section having a tightening head for tightening the object to be tightened, and a tail section that extends from the tightening head pivotally supported with respect to the handle via a head pin; torque-detecting mechanisms for detecting when the torque for tightening the object being tightened reaches the specified torque; and a rotation angle-measuring section for measuring the rotation angle of the angle wrench in a tightening action, on the basis of the angular velocity of the angle wrench around the axis of the object being tightened, after the torque-detecting mechanism has detected that the specified torque has been reached.

摘要： An object is to provide a torque tool device which can expedite tightening operations using a torque tool without requiring any other manipulation than the tightening. The device is also capable of performing tightening operations consecutively by determining instantly whether the tightening has been adequately performed.The torque tool device includes a torque tool 1 and an information processing terminal 20. The tool 1 is capable of measuring the torque value at which a bolt or the like was tightened and then transmitting the measured torque value via wireless communication means. The terminal 20 has information processing means for receiving the measured torque value and determining whether the torque value is acceptable. This arrangement eliminates the need of including a pass/fail test device in the torque tool 1, thereby allowing it to be reduced in weight. Additionally, the wireless communication using the ISM frequency band can allow the determination result to be instantly sent and received, thereby making it possible to expedite the tightening consecutively with the torque tool 1.
