  • Patent number: 11358027
    Abstract: A non-limiting example training instrument comprises a hollow main body formed of an aluminum alloy. The main body is constituted by two gripping portions opposite to each other with a space therebetween and a coupling portion coupling the two gripping portions. A load sensor is arranged in the coupling portion inside the main body. The load sensor is a load cell, a strain gauge affixed to an interior of the main body, and a part of the main body to which the strain gauge is affixed functions as a strain body. Therefore, if a user applies a force so as to bring the two gripping portions close to each other or a force so as to move the two gripping portions away from each other, a load thereof is detected by the load sensor.

  • Publication number: 20220152792
    Abstract: A screw-tightening tool includes a housing, a spindle, a motor, and a power-transmitting mechanism including a sun member, a ring member, a carrier member and a planetary roller. The power-transmitting mechanism is configured such that, when the ring member moves rearward to be closer to the sun member in response to rearward movement of the spindle, the planetary roller transmits power of the motor to the spindle owing to frictional force between the planetary roller and each of a first tapered surface of the sun member and a second tapered surface of the ring member. The sun member is configured to move from a first position to a second position, which is forward of the first position, when the frictional force reaches a threshold, and to move from the second position to the first position when the frictional force falls below the threshold.

  • Patent number: 11045861
    Abstract: A fastening tool includes a bolt-gripping part, an anvil, a motor, and a control part. When the bolt-gripping part grips an end region of a shaft part and moves relative to the anvil in a first direction of a longitudinal-axis direction, the anvil presses a collar fitted onto the shaft part in a second direction opposite to the first direction of the longitudinal-axis direction and inward in a radial direction of the collar, so that a hollow part of the collar is crimped to a groove while the workpiece is clamped between the collar and a head part, whereby swaging of a fastener is completed while the end region remains integrated with the shaft part. The control part completes swaging of the fastener by terminating a movement of the bolt-gripping part in the first direction relative to the anvil based on driving current of the motor.
