摘要： PROBLEM TO BE SOLVED: To enhance the resolving power of fastening angle at the time of measuring angle by a screw fastening machine employing the angle method, and thereby heighten the accuracy of measured values of angles. SOLUTION: A sensor base 21 is fixed on the projected face of a ratchet shaft 14 of a preset type torque wrench head part, and a sensor gear 24 is journalled to the sensor base 21. Then, an angle sensor 27 which corresponds to the sensor gear 24, is fixed and a ring gear 28 on the outer peripheral surface of which a gear part 30 is formed, is journalled to the outside of the ratchet shaft 14 so that it is concentric with the ratchet shaft 14 and rotatable with respect to the ratchet shaft 14. The gear part 30 is gear-connected to the sensor gear 24 through a speed increasing gear, the gear ratio of which is smaller than that of the gear part.

摘要： PROBLEM TO BE SOLVED: To easily calculate a reference value using a snag torque generation point as a reference by mounting a geomagnetic sensor on torque equipment. SOLUTION: A geomagnetic sensor 13 receives a voltage wave form output and determines the direction of torque equipment with respect to a geomagnetic direction within an angle range of 0 to 360 degrees. A declination detection output from the geomagnetic sensor 13 is digitized by a converter 103 and supplied to a microcomputer system 110. Then, when an output from a torque sensor 17 is equal to a set output value by the snag point setter 101 of the setter 101, a gate 111 is closed and by the output of this time, the snag declination θ0 of the torque equipment with respect to the geomagnetic direction is stored in a memory 112.

摘要： PURPOSE:To accurately display a set torque value by comparing the voltage corresponding to the set torque value with the voltage appearing accompanying the falling and rising of torque and calculating the max. peak value among candidate values. CONSTITUTION:A strain gauge 11 converts torque into voltage and this voltage is amplified to voltage VA by an amplifier 13. This voltage signal VA is compared with the peak value VB stored in a peak holding circuit 15 by a comparator 111 to detect the width of a trough. The signal from a timing circuit 114 having prescribed timing DELTAt0 and the signal from a phase reversal circuit 112 are synthesized on the basis of the detection signal by a synthesizing circuit 115 to be stored in a memory 117. In the same way, signals VA, VB are compared by a comparator 119 and, when a trough is prescribed falling quantity DELTAT0, this quantity is stored in a memory 120. The signals stored in the memories 117, 120 operate gate circuit 16 through an AND circuit 118 and the signal VB of the circuit 15 is converted into a signal VC by a peak holding circuit 17 and the ridge value VP of torque is displayed on a display device 18. By this constitution, the max. peak value wherein the time required before dropped voltage rises to reach set torque voltage is a prescribed value or less and dropped voltage is the prescribed value or more among set torque candidates is set to a set torque value.

摘要： PURPOSE:To obtain a holding device for an axial force measuring sensor which is designed to enhance the measuring accuracy. CONSTITUTION:A measuring surface 15-1 of a sensor 15 held within a holding cylinder 11 is urged to project from an opening edge of the holding cylinder 11 when the sensor receives the elastic force of a spring 17. Therefore, when the opening edge of the holding cylinder 11 holding the sensor 15 is attracted to the top face of a bolt 20 by the attraction force of a magnet 12, the measuring surface 15-1 of the sensor 15 is brought in tight contact with the top face of the bolt by the elastic force of tone spring 17. Even if a foreign article is inserted between the opening face of the cylinder 11 and the top face of the bolt and the opening face of the cylinder 11 is inclined, the measuring surface 15-1 of the sensor 15 is kept in tight contact with the top face of the bolt by the elastic force of the spring 17. Accordingly, the reliability of the measurement is improved.
