  • Publication number: 20240035816
    Abstract: An automatic measuring device includes a micrometer including a spindle that moves forward and backward to be brought into contact with or away from a workpiece and a displacement detector unit that detects displacement of the spindle, and an automatic operation unit that automates the forward and backward movement of the spindle by power. The automatic operation unit performs a first forward-movement step of moving the spindle forward to bring the spindle into contact with the workpiece, and a contact determination step of determining the contact between the spindle and the workpiece in the first forward-movement step. In the contact determination step, the spindle is determined to be in contact with the workpiece when a change in a position of the spindle detected by the displacement detector unit in the first forward-movement step becomes equal to or less than a predetermined contact determination threshold.

  • Publication number: 20230324161
    Abstract: There is provided an inside-diameter measuring unit capable of automating inside-diameter measurement and a control method for automatic inside-diameter measurement. An inside-diameter measuring part is supported by a support frame part via a floating joint part. The floating joint part includes a rotation-allowing mechanism part and a translation-allowing mechanism part. A measuring head part of the inside-diameter measuring part is inserted into a hole by a robot arm part. The inside-diameter measuring part adjusts its position and posture autonomously by the reaction force when a contact point pushes against the inner wall of the hole to align the axis of the inside-diameter measuring part with the axis of the hole. An electric inside-diameter measuring unit can automatically measure the inside diameter of a hole.

  • Patent number: 11466971
    Abstract: There is provided an automatic measurement device that automates a contact type measuring instrument, which is inexpensive and good usability. An automatic measurement device includes a measuring instrument support base portion that supports a measuring instrument and a workpiece holding base portion that holds a workpiece in a measurement region of the measuring instrument. The measuring instrument support base portion includes a measuring instrument holder that holds a fixed element of the measuring instrument and an automatic operation unit attachable to and detachable from the measuring instrument. The automatic operation unit is configured to automate advance and retreat of the movable element of the measuring instrument by a power from a motor.

  • Patent number: 11260869
    Abstract: A control device for an automatic transmission includes: a failure diagnosis section for diagnosing whether or not a failure has occurred in a shift control system of the automatic transmission; a fail-safe control section for fixing the automatic transmission into a predetermined gear position in response to confirmation of the failure of the shift control system of the automatic transmission; and an oil temperature rise regulation torque reduction control section for outputting a torque reduction request to suppress torque of a vehicle driving source, based on temperature of transmission operating oil of the automatic transmission, and outputting the torque reduction request in response to satisfaction of an oil temperature condition that is set lower in oil temperature when the automatic transmission is fixed in a first gear position by the fail-safe control section than when the automatic transmission is not fixed in the first gear position.
