摘要： A minimum value renewal holder (33) for renewing and displaying a detected value (D) detected by a displacement sensor (9) on a display (10) when a spindle is moving in an advancing direction relative to an anvil and for holding a displayed value on the display (10) when the spindle moves in a retracting direction relative to the anvil and a retraction amount thereof (D - Dm) is less than a set amount (α) , and a minimum value hold releasing potion (34) for releasing minimum value hold status when the spindle moves in the retracting direction relative to the anvil and the retraction amount (D - Dm) is not less than the set amount (α) are provided. Accordingly, the displayed value can be kept even when the anvil backs unpreparedly.

摘要： A micrometer includes: a main body having an anvil at one end thereof, a spindle having a screwed portion engaging an opposite end of the main body and being displaceable in an axial direction and with respect to the anvil in conjunction with rotation of the spindle, and an encoder detecting an axial displacement amount of the spindle from a rotation amount of the spindle, so that a measurement value based on an output signal of the encoder is digitally displayed. The micrometer includes a thimble provided on the opposite end of the main body and the thimble is rotatable about the axis of the spindle at a predetermined position in the axial direction of the spindle. The thimble is formed with a guide groove parallel with the axial direction of the spindle in an inner peripheral surface thereof. The spindle includes an engagement pin located in the spindle and slidably engaging with the guide groove of the thimble.

摘要： A main scale graduation, an auxiliary scale graduation or the like provided in a conventional micrometer is omitted, and a thimble 71 is provided at a regular position in the axial direction of the spindle 61 through a sleeve 51 in a frame 1 to rotate about the axis of a spindle 61. Between the thimble 71 and the spindle 61, a rotation transfer means 81 for transferring the rotation of the thimble 71 to the spindle 61 and allowing the spindle 61 to displace in the axial direction of the spindle 61. As the rotation transfer means 81, a ratchet system 82 is used.

摘要： The disclosed digital display micrometer comprises essentially a gun-like body (10) provided with a trigger (11) connected to a moving carriage (35) carrying a piston (38). A measurement part (13) may be adapted to a fixing head (12) provided with a surface plate (24) forming a reference surface. A thrust spring (45) connected to a slide (43) provides for the displacement of the carriage and the piston in order to act on a sliding rod housed inside the part to be measured.

摘要： The invention concerns a portable displacement measuring instrument, notably a micrometer, that comprises a body (11), an anvil (2), a spindle (3) moveable with respect to the body (11), an encoder (7) detecting an axial displacement of the spindle, a rotationally-mounted thimble (4) being actionable by a user for bringing the spindle (3) into contact with a workpiece and a transmission mechanism being provided between the thimble (4) and the spindle (3) for converting a rotation of the thimble in a translation of the spindle towards the anvil. The transmission mechanism comprises a constant force mechanism configured for disengaging the transmission mechanism when a movement of the spindle towards the anvil is opposed by a load being equal or surpassing a threshold load. The constant force mechanism (5) comprises an adjusting mechanism (51, 511, 52, 55) arranged for setting the threshold load within a predefined range.
