With Control For Adjustment Means Responsive To Activator Stimulated By Condition Sensor Patents (Class 409/207)
  • Patent number: 11879805
    Abstract: A method for spin set bearing setting verification in a preload state on a shaft. An inertia wheel may be disposed on the shaft. The inertia wheel or the shaft is rotated. A first rotational speed is measured at a first time. The inertia wheel may decelerate over time to achieve a second rotational speed measured at a second time. The second speed is less than first speed. The change in time between the first time and the second time is measured. The bearing setting may be adjusted if the change in time is outside a predetermined time range. The bearing setting may remain unchanged if the change in time is within a predetermined time range.

  • Patent number: 8757941
    Abstract: A cutting plotter includes a medium supporter, a first guide rail, a second guide rail, a carriage, a work tool, a working controller, and a second direction displacement detector. The second direction displacement detector is configured to measure a second guide rail displacement amount. The second guide rail displacement amount indicates a magnitude of displacement of a moving path of the carriage from a predetermined moving path with respect to the second guide rail in a direction perpendicular to a second direction when the carriage is moved in the second direction along the second guide rail. The working controller is configured to execute a control in which a movement control of the second guide rail on the first guide rail is added so that the second guide rail displacement amount is corrected in a movement control of the carriage on the second guide rail.

  • Patent number: 8740523
    Abstract: By controlling an amount of preload applied to a rolling bearing that supports a spindle in accordance with the change of state of the spindle in actual machining, the rotation of the spindle is controlled in an optimal state, and the service life of the bearing is extended while the required stiffness of the spindle is ensured. When a corrected preload amount falls outside a range of a preload as a controllable region, the corrected preload amount is corrected so as to fall within the range of the preload. That is, an actually controlled preload is regulated to fall within the preset range of preload. Therefore, it is possible to ensure the stiffness of the rolling bearing or prevent heating and excessive increase in contact pressure of the rolling bearing.

The ultrasonic waves emitted by the first ultrasonic probe are transmitted to the work piece, and are transmitted back to the first ultrasonic probe, by a first column of liquid which is created by the first measuring arrangement and situated between the first ultrasonic probe and the work piece for measurement. The measurements are used for automatically adjusting the position of the tool relative to the work piece during machining the work piece.

    Abstract: The present disclosure teaches a process and related apparatus for longitudinal adjustment of tools for individual working spindles of a multiple-spindle automatically controlled machine tool. The tools introduced into the working spindles in the direction of their lengths to be adjusted are run in rapid advance in all cases against a measuring device which, on reaching a predetermined distance from the working part reference point, produces a first signal in which the rapid advances of the working spindles are switched off individually. The first signal from the measuring device finally reached by the tool involved switches on crawling speeds for all working spindles. The spindles are switched off individually on reaching the working-part reference points in all cases by a second signal from the measuring devices.

  • Patent number: 4178834
    Abstract: An improved machine tool includes an extendible ram or tool support arm. As the ram is extended, the outer end portion of the ram deflects downwardly under the influence of gravity. To compensate for the deflection of the ram, the angular orientation of the ram relative to upwardly extending tracks is changed to raise the outer end portion of the ram. This is accomplished by means of gibs or deflection compensation cams which are moved to rotate a carriage or saddle on which the ram is mounted. The extent of deflection of the ram varies as a function of the distance which it extends outwardly from the carriage. Therefore it is necessary to store data indicative of the deflection of the ram at various degrees of extension and to adjust the orientation of the ram in accordance with this data as the ram is extended. The data indicating the extent to which the ram deflects is stored by means of a cam mounted on the carriage. The cam is read by a transducer which moves with the ram.
