  • Publication number: 20240142214
    Abstract: There is provided a measuring device that is inexpensive and easy to use, yet provides sufficient accuracy and resolution in continuous scanning measurement to measure workpiece surfaces. A dial gauge includes a spindle provided to be movable reciprocatively in an axial direction through a main body case. The main body case includes a stem provided to protrude from a side face of the main body case. A ball bearing that bears the spindle is provided inside the stem. A workpiece and the dial gage are relatively moved while a contact point at the tip of the spindle is in contact with the surface of the workpiece, and continuous scanning measurement is performed to measure irregularities of the surface of the workpiece or the amount of runout of the rotating workpiece.

  • Publication number: 20240133667
    Abstract: A small-sized measuring device includes a position detector that is provided on a main body and detects the position of an object to be measured, a timer that measures time, and a central control unit that controls overall operation. The central control unit accepts a base-point setting standby time set by a user and stores the base-point setting standby time. The central control unit measures elapse of the base-point setting standby time after accepting an instruction to start measuring time from the user, performs a base-point setting step of setting the position of the object to be measured detected by the position detector as a base point after the base-point setting standby time has elapsed, and then measures the position of the object to be measured as a relative position from the base point.

  • Publication number: 20240133666
    Abstract: A small-sized measuring device includes a position detector that is provided on a main body and detects the position of an object to be measured, a photosensor, and a central control unit that controls overall operation. The photosensor is configured to function at least as an input device configured to accept a base-point setting instruction from the user. The central control unit, when accepting the base-point setting instruction from the user through the non-contact input sensor, performs a base-point setting step of setting the position of the object to be measured detected by the position detector as a base point, and performs a measurement step of measuring the position of the object to be measured as a relative position from the base point.

  • Patent number: 11499821
    Abstract: A gauge inspection jig for performing an inspection easily and accurately in a reverse posture with a contact point facing upward when a gauge is inspected. The gauge inspection jig includes a body portion and a coupling portion. The body portion holds a member mounted to a body portion of the gauge. This holds the gauge in the reverse posture. The coupling portion is coupled to the body portion. The coupling portion is couplable to a distal end of a measurement spindle disposed on a gauge inspector to be movable in a measurement axis direction.

  • Patent number: 11268797
    Abstract: A coupling portion has one end coupleable to a distal end of a measurement spindle. The measurement spindle is disposed on a gauge inspector and movable in a measurement axis direction. A cylindrical stem is insertable into a gauge holding member to hold the inserted stem. The stem slidably holds a spindle having a distal end on which a contact point of a gauge is disposed. A frame has a first end coupled to a second end of the coupling portion and has a second end to which the gauge holding member is mountable. The gauge holding member is held to the frame such that an axis of the stem runs along the measurement axis direction. As a result, inspection is performed easily and accurately in a reverse posture with a contact point facing upward when a gauge is inspected.
