Dimension measuring instrument having a probe moving along a measuring axis. An elastic transmission element allows the probe to move under the action of the measuring force. If necessary, the probe can be coupled rigidly with the instrument, for example to perform profile measurements or tracings. The instrument is entirely protected by a casing from liquid projections and dust, and the probe can be locked without opening the casing or accessing its inside.

Dimension measuring instrument and height gauge

Touch probe including a fixed part (), designed to be fastened onto a measuring machine or a machine tool, and a contact feeler () that is mobile and orientable on two independent axes () along a multiplicity of directions indexed in space. An actuator () comprising antifriction rollers and a ball bearing allows the rotation axes () to be unlocked and any orientation to be selected with minimized friction. In locked position, the actuator () withdraws under the action of return springs () so as not to influence the indexing accuracy.

Probe for three-dimensional measurements

Tool-switching device for a machine for measuring coordinates wherein the tool is fastened on the tool-carrier and held by the action of elements exerting an axial force. The locking force is taken over symmetrically by the elements of a Boys connection, which increases the repeatability of the connection; in one embodiment, two pins or spheres are driven by a sliding bushing provided with two 'V'-shaped slits or with two lateral gorges. In the subsequent embodiments, the pins are replaced by spheres, by levers or by a stirrup.

Tool-switching device

A vertical length measuring device () is disclosed that comprises a vertical guide (), at least one carriage () that is led vertically by the guide (), and a driving organ () for the at least one carriage (). A housing () placed around the vertical guide (), the carriage () and the driving organ (), has a longitudinal opening (), and is fastened at a foot () of the length measuring device (). A measuring head () is placed outside the housing () and is connected with the carriage through the opening () of the housing (). The invention is characterized in that behind the opening () of the housing () inside the housing (), a baffle () is placed. This advantageously prevents penetration of oil, water and dirt from outside.

Height gauge

Reference gauge for calibrating measuring machines whose reference dimension can be measured both on its inner size and by its outer size, thus making it possible to keep the reference dimension less than 15 millimeters, even for calibrating measuring machines equipped with probe tips having a diameter greater than that dimension. The calibration method with the aid of such a reference gauge comprises in certain cases the measuring of the calibrated distance between two outer surfaces of a protruding volume.

Touch-triggered probe comprising a fixed part, designed to be fastened onto a measuring machine or a machine tool, and a mobile contact feeler that can be oriented on two independent axes along a multiplicity of spatial directions.

Adjustable probe

Touch-triggered probe comprising a fixed part, designed to be fastened onto a measuring machine or a machine tool, and a mobile contact feeler that can be oriented on two independent axes along a multiplicity of spatial directions. The two axes of the probe comprise each an actuator for unlocking and adjusting the axes. The operation force is reduced as compared with the high effective indexing force by a demultiplying mechanism having an increasing transmission ratio, for making easier the operation in unlocked position. The indication elements can easily be read whatever the feeler's orientation.

Column for measuring longitudinal dimensions

Trigger probe, constructed on the principle of the Boys connection, serving to detect the contact between the probe's stylus and a piece to be measured, comprising an electric circuit with at least one switch, whose contact elements are positioned by means of several connecting elements of the circuit.

Trigger probe and method for assembling a trigger probe

Height-measuring column comprising a supporting frame fastened to a base, said supporting frame determining the measuring axis, it being possible to regulate the perpendicularity between the supporting frame and the base and method for regulating the perpendicularity of a height-measuring column relative to a reference surface by regulating the perpendicularity between the supporting frame and the base of said height-measuring column.
